Description

[Detailed Description of the Invention] [Subject of the Invention] The present invention provides a carriage for a hand knitting machine in which the butt passages for knitting needles necessary for pattern knitting such as lace knitting and two-color simultaneous knitting are configured in the same integral carriage. It is related to.

[Prior art]

Conventionally, in order to perform lace knitting by transferring a stitch loop suspended from a knitting needle to another knitting needle, the stitch loop is first transferred using a designated carriage that only performs stitch transfer, and then the stitch loop is transferred to a separate knitting needle. The formation was completed using the formation carriage. However, this method has the disadvantages described in the next section, and as a countermeasure, technical improvements
2-16356, JP-A-49-31950. Opening/closing 56-
134238, Japanese Patent Publication No. 56-134239) In other words, an integrated carriage is known which enables stitch transfer followed by stockinette knitting.

[Problems with the prior art and technical analysis thereof] The former method in the prior art required a great deal of time and effort to operate, and the work involved in organizing was extremely troublesome. Although the latter improved techniques mentioned above are designed to solve this problem and make the lace knitting itself easier, each of them has at least one or more of the following disadvantages.

(Disadvantages) That is, (11) While lace knitting can be easily performed, pattern knitting such as two-color simultaneous knitting is not possible or cannot be easily performed.

(2) In order to separate the sliding for stitch transfer and the stockinette stitch after transfer into separate courses, the knitting yarn must be taken in and out of the yarn opening for each course, which is extremely troublesome in operation. Accompany.

(3) Stockinette knitting is possible after stitch transfer, but pattern knitting such as two-color simultaneous knitting is not possible at all.

(4) Due to the configuration, the horizontal length of the carriage inevitably increases.

[Technical issues]

In order to solve the above-mentioned problems of the conventional technology, in this application, all the needle passages required for pattern knitting such as lace knitting and two-color simultaneous knitting are integrated into the same carriage without particularly increasing the left and right length of the carriage. The challenge is to configure it in an integrated manner.

[Technical means]

In the present invention, the above problem was solved by the following means. That is,
Sub-stockinette knitting paths are formed inward of the knitting cams and raising cams on the left and right sides of the carriage center, which act only during lace knitting, so that stockinette knitting is performed in the same sliding motion immediately after stitch transfer. Along with this, cam passages for stitch transfer were provided on the left and right outer sides of the cam. In this passage, various cams acting on the knitting needle butts are switchably arranged so as to provide a cam passage necessary for pattern knitting such as two-color simultaneous knitting.

Furthermore, one of a pair of removable knitting devices is installed on the front side of the carriage, depending on the case of lace knitting or pattern knitting such as two-color simultaneous knitting. .

[Effect of technical means]

A stitch transfer device provided on the carriage guides the selected knitting needles at each position into two different positions, and brings the selected set in each passage closer to the front part by lateral movement of the carriage. At the same time, by sliding both knitting needles back and forth, the stitch loops are directly transferred between the two knitting needles. Immediately after that, the knitting needles are slid back and forth, and in addition to the normal knitting action by the knitting cam and the raising cam, the sub-stockinette knitting path, which only works during lace knitting, allows the relative movement of the needle bed and carriage. Along with this, the stockinette section is performed, followed by the lace section all at once.

In addition, in pattern knitting such as two-color simultaneous knitting, this sub-stockinette knitting passage has a changed corresponding function by using it as a pattern cam.

Then, the course of the knitting needle bat is changed in the left-right direction of the knitting cam and raising cam to the entrance of the passage necessary for pattern knitting such as two-color simultaneous knitting, for stitch transfer and succession. It was made common by the action of various cams.

[Special effects produced by the present invention] Sub-stockinette knitting passages that act only during lace knitting are formed on the left and right inner sides of the knitting cam and the raising cam,
On the other hand, in pattern knitting such as two-color simultaneous knitting, this can be used as a pattern cam to change its correspondence, and many patterns can be knitted by working together with the knitting cam and the raising cam.

In addition, on the left and right sides of the knitting cam and the raising cam, a passage for stitch transfer and a passage for stitch succession for lace knitting are installed up to the entrance of the passage necessary for pattern knitting such as the two-color simultaneous knitting. Since the cams that guide the course change of the knitting needle hats are arranged in both the lace knitting passages, a part of the passage can be shared. This allows for a compact configuration without increasing the horizontal length of the carriage. In the carriage of the present invention, by switching the cam and using a pair of knitting auxiliary devices, pattern knitting such as lace knitting to two-color simultaneous knitting can be easily knitted with the same carriage.

〔Example〕

Reference numeral I designates a needle bed on which a large number of knitting needles 2 and comb teeth 3 are arranged.

Each of the knitting needles 2 is particularly capable of sliding back and forth, and its front portion can be curved in the lateral direction past the comb teeth 3 up and down to the position of an adjacent knitting needle.

A carriage 4 is mounted so as to be slidable left and right on the front and rear sliding legs 5 and 6 of the needle bed, and the following cams are formed and arranged symmetrically on the lower surface of the carriage. That is, 7 and 8 are the front and rear bulkheads forming the front and rear body passages, respectively, and the left and right intermediate portions between the two corner walls have partitions for making various knittings such as two-color simultaneous knitting. Along with the cams, stitch transfer cams are arranged on both the left and right sides of the cams.

Reference numeral 26 denotes a path switching cam provided inside the front guide cam 20, which is provided at the connecting portion between the knitting front path and the stitch transfer path, and which transfers the same stitch without changing the butt of the knitting needle in the stitch transfer path. It is arranged so as to be switchable between a state in which it is advanced to a private passageway and a state in which it is introduced into a rear formation passageway. Reference numeral 27 denotes a fixedly formed inner front guide cam, which has a generally four-sided shape, and has a bearing portion rotatably receiving the path switching cam 26 at its outer corner, and its front portion is connected to the front guide cam 27. A knitting needle butt passage is formed between the partition wall 7 and the rear side surface thereof. Further, a retreat passageway connected to the forward switching position of the knitting cam 15 is formed on the outer inclined surface, and a passageway through which the knitting needle butt is advanced forward by the knitting cam 9 is secured on the inner inclined surface. In addition, a passageway is also formed in the front inward direction, through which the auxiliary switching cam 16 can be retreated when switched forward. Reference numeral 28 denotes a switching cam that can be switched between two positions: a position for retracting the knitting needles that have inherited the stitches, and a path that connects to the front guide cam 27. Reference numeral 29 is for retracting the knitting needles that have inherited the stitches introduced by the switching cam 2B. Fixed rear guide cam. Next, regarding the needle selection device provided in this carriage, reference numeral 30 indicates a position where the knitting needle hats introduced by the knitting cam 9 and the raising cam 15 are introduced into the needle selection preparation position, and a position where the knitting needles are not introduced.
This is a needle selection selection cam that can be switched to a different position, and its rotation axis supports an introduction inclined surface 31 for lowering the butt part of the knitting needle to a locking member (not shown) of the S plate (needle selection member). and a protrusion 32 necessary for the existing needle selection device that provides the necessary margin to lock the rear shank portion of the knitting needle butt with the S plate while the butt is pressed down. Reference numeral 33 is a needle selection and selection cam that tilts from the front to the rear to remove the needle butts that have entered this passage horizontally outward from the protrusion 32, and the central part is for removing the low butt that has been lowered and locked by the protrusion cam 32. Let them pass sideways,
In addition, the high bat that is not locked has a height that cannot be passed through, and has a guide portion that guides the bat to the rear by its inclination.

The front portion is shaped to introduce the butt of the stitch succession knitting needle that enters from the outside of the carriage to the switching cam 28 position. Reference numeral 34 denotes a path switching cam that can switch the butt of the knitting needle that inherits the stitch to two positions: a path necessary for stitch transfer and a path unrelated to the transfer. form. Reference numeral 35 denotes a fixed partition cam located in front of the convex cam 32 and whose front edge introduces the needle butt into the switching cam 28 position.

36 is a low butt release cam adjacent to the outside of the needle selection and selection cam 33, which lowers the low butt again to the side adjacent to the needle selection and selection cam 33, lowers the needle and shank again, and releases the S plate (needle selection and selection cam). board-
(not shown), and a rear slope that allows the knitting needle butt to return to its conventional high position after the S plate is released. Forming a passage introduced by the cam.

Next, on the front side of the carriage 4, there is installed a pair of auxiliary devices that can be replaced and removed depending on the case of lace knitting or pattern knitting other than lace knitting, such as two-color simultaneous knitting. So I will explain this. First, to explain the stitch transfer auxiliary body A used for lace knitting, 40 in the figure
is a board made of a sheet metal member bent into a substantially U-shaped cross section with an opening at the rear, and male screws 42 of tightening screws 41 provided on the left and right sides of the front of the carriage 4 at the rear end of the upper flat part. A pair of left and right fitting grooves 43 are provided so as to fit into each other. The substrate 40 can be attached to and detached from the carriage 4 by tightening screws 41, and an opening groove 44 that opens upward, downward, and forward is provided at the front side of the substrate 40 between the left and right sides. Reference numeral 45 denotes a yarn opening plate whose base end is fixed to the inner side of the left and right center of the substrate 40, and is provided with a supply hole 46 for supplying the knitting yarn T. Stitch passing devices are provided on the left and right substrates of the yarn opening plate 45, respectively. The stitch transfer device A includes a needle raising cam 47 that raises the front part of the knitting needle 2 in the stitch transfer path Y1 above the upper end of the comb teeth 3, and an opening of the knitting needle 2 raised by the needle raising cam 47. A slip-out prevention member 48 is provided which engages with the lower surface of the latch and prevents the stitches suspended above the latch from coming off. Also, the needle opening raising cam 49 that raises the front part of the knitting needle 2 in the stitch succession passage X1 to a position slightly above the upper end of the comb teeth 3, the needle raising cam 47, and the knitting needle under the action of the member 48 that prevents flatness from being pulled out. A needle bending member 50 is provided which curves the front portion of the knitting needle 2 until it intersects above the hook of the knitting needle 2 of the stitch succession passage X1 adjacent in the sliding direction of the carriage. In addition to this configuration, the front portion of the knitting needle 2 curved by the member 50 is connected to the inner step portion 51 of the needle raising cam 47.
By coming off and descending, the stitch inheritance passage X
The knitting needles 2 cross-joined to the hooks of the knitting needles 2 of 1 and in the stitch succession path X1 are advanced by the front inclined surface of the needle selection and selection cam 33. As a result, after the hook enters the stitch of the knitting needle 2 in the stitch transfer path Y1 from the rear, the front part of the knitting needle 2 in the stitch transfer path Y1 is again raised above the upper end of the comb teeth 3, and stitch succession is performed. It is constructed by providing a return cam 52 that moves the knitting needle 2 away from the hook in the passage xi and returns it to its original position. The above-described operation of the stitch passing device A is performed according to a known method, and the knitting needles 2 of the stitch transfer passage Y1 and the knitting needles 2 of the adjacent stitch succession passage X1 are connected to the corresponding course switching cam 26. ．． Inner guide cam27. It retreats through the passage formed by the raging cam 15.

On the other hand, the passage for stitch succession is provided by the switching cam 28. Rear guide cam 29
Retreat through the passageway. In this case, the knitting needles in the stitch transfer path reach the rear end of the raising cam 15, thereby coming to a knockover position (a position where the stitch is removed from the hook forward) and removing the stitch. On the other hand, the knitting needle 2 that has passed through the stitch succession path holds in the hook two stitches: the stitch held before entering the carriage and the stitch transferred by the stitch transfer device A, and the stitch transfer operation is completed. In the figure, reference numeral 53 designates magnets fixed to the inner surfaces of the left and right sides of the substrate 40, which cause the latch of the knitting needle 2 of the stitch succession passage X1 to open in an upright position just before the flatness prevention plate 48. 54 is the clue #i! 45 and the stitch passing device A, the substrate 4
The inner magnet fixed to the inner upper part of the thread guide plate 4
The latch of the knitting needle that receives the yarn at the yarn opening 46 of No. 5 is opened and raised.

On the other hand, to explain the knitting auxiliary body used in pattern knitting such as two-color simultaneous knitting, reference numeral 60 in the figure is a support plate bent in a cross-sectional shape, and the rear edge of the upper plane part. A pair of left and right fitting grooves 43 are provided on the left and right sides of the screw 41 to fit into the male threaded portion 42 of the screw 41, and the screw 41 can be tightened and removed. Reference numeral 61 denotes a plate-shaped silk presser fixed to the left and right sides of the front lower surface of the support plate 60, which is close to the front edge of the comb teeth 3 to prevent the knitted fabric from advancing, and has a knitted fabric (not shown) on the lower surface thereof. Brush wheels and other equipment are supported to prevent entry. Reference numeral 62 denotes a yarn opening plate whose base plate is fixed to the upper and lower surfaces of the left and right center portions of the support plate 60, and at the left and right center portions of the lower plane portion, coloring knitting yarns T2 are attached to the hooks of the knitting needles 2 of the front knitting path W2. A front yarn opening 63 for supplying the ground knitting yarn T1 and a rear yarn opening 64 for supplying the ground knitting yarn T1 to the hooks of the knitting needles 2 of the rear knitting path 1 are provided. Reference numeral 65 is a brush fixed to the upper part of the support plate 60 on the right and left sides of the yarn opening plate 62, and opens the latches of the knitting needles 2 in the front knitting passage W1 and the rear knitting passage 1.

Next, lace knitting, two-color simultaneous knitting knitting, stockinette knitting,
How to perform patterns such as slip knitting and tuck knitting will be explained. First, starting with the race shown in Fig. 1, the auxiliary transfer body A is attached to the front side of the carriage 4 and fixed by tightening the screws 41, and the various cams on the bottom of the carriage 4 are tightened. They are placed at each position shown in FIG. Furthermore, the knitting needles 2 in the knitting section involved in knitting the knitted fabric are sorted into a knitting preparation position X1 and a needle selection position Y1 by a needle selection means to be described later. (In this case, the selection is made so that two or more knitting needles 2 at the needle selection position Y1 are not selected consecutively.) After this, by sliding the carriage 4 from the outside of the knitting section into the same section, The knitting needle at the selected position is Yl as shown in
At the same time, the knitting needles 2 at the knitting preparation position X1 are introduced into the stitch succession passage connected by the two-dot chain line indicated by X2. These knitting needles 2
By the time the butt is guided to the inner side of each passage, the stitches suspended from the knitting needles 2 of the stitch transfer passage Y1 are transferred to the adjacent stitch succession passage X1 on the front side in the carriage sliding direction according to a known method. is hung on the hook of knitting needle 2. After this, the stitch transfer path Y1 is moved backward by the 26 course switching cam 27 and the parallel raising cam 15, and the knitting needle 2 reaches the knockover position (the position where the stitch comes off the hook forward) and removes the stitch. Complete stitch transfer.

On the other hand, the knitting needle 2 that has entered the stitch succession path After merging, the stitch transfer of the knitting needles 2 on both roads is completely completed.

Thereafter, the two needle paths merge, and the latch of the knitting needle 2, which is moved forward by the tuck cams 14 on both the left and right sides of the central guide cam 12 that overlaps the central front guide cam 11, and which has come loose on the way, is opened by the magnet 54, and the knitting needle 2 is opened by the magnet 54, and Board 45
The hook part reaches the bottom surface of the. (FIG. 4) Here, after the knitting yarn T is supplied to the hook portion of the knitting needle 2 through the yarn port 46, the butt portion is moved back by the inclined surface located at a high position of the one-way cam 17. Next, the needle butt is connected to the inner inclined surface of the intermediate wall 10, the movable retraction cam 13. The knitting needles 2 that have passed through the knitting cam 9 and the stitch succession path X1 reach the knockover position again and form a stitch. On the other hand, the knitting needles that have passed through the stitch transfer path Y1 are
With the knitting needle T still being supplied into the hook, a complete stitch has not yet been formed. After that, each butt part of the knitting needles 2 in both passages is introduced into the lowering cam 32 by the needle selection and selection cam 30, where all the needle butts are at a low position where the amount of protrusion from the groove plate is small, and the knitting needles 2 are The knitting needles are sorted and differentiated into knitting needles that are engaged with the S plate (needle selection plate - not shown) on the shank and knitting needles that are not, and after passing through the lowering cam 32, the butt height of the engaged knitting needles 2 is at a low position. is maintained.

On the other hand, the butt of the knitting needle 2 that is not engaged returns to its original high position. Thereafter, when passing through the needle selection and sorting cam 33, depending on the height of the wall that stands up, low butts pass through as is, while high butts cannot pass through, and the butt part retreats due to the inclined side wall.

As a result, the knitting needles 2 are selected by the needle selection device using a known selective selection method and reach the outside of the carriage 4, but these S plates (
Whether or not the needle selection plate (needle selection plate) moves to lock the shank of the knitting needle 2 in a uniformly lowered position is determined by the S installed at the rear of the groove plate.
A conventionally known method is used (not shown), with or without a hole for an inserted punch card in the driving device of the plate. However, here, the knitting needle 2 that has passed through the previous stitch transfer passage does not form a complete stitch loop with only the knitting yarn T hanging around its hook, so the return slide of the subsequent carriage 4 requires an additional stage of organization. Therefore, all the holes in the punched card are in the internal state (the state in which the S plate does not move for locking).
Assume that it is set to . However, all the butts that have passed through the protrusion 32 for pressing down the butts of the knitting needles 2 are placed at a high position with respect to the groove plate 1, so that they do not pass laterally through the upright wall of the needle selection and sorting cam 33 and are moved rearward. The tip of the course switching cam 34 is in spring pressure contact with the rear partition wall 8 at the rear, and the knitting needle is opened in the hat of the knitting needle 2, and the knitting needle is moved to the outside X2 of the carriage 4 shown in FIG. Once aligned, one sliding movement of the carriage is completed.

Next, the sliding movement of the carriage 4 in the opposite direction to the sliding direction described above will be explained based on FIG. 5. After the butt part of the tip of the course switching cam 34 passes through the opening in the carriage sliding direction, it returns to the rear partition wall 8 side again by the spring, and the butt of the knitting needles 2 aligned in X2 is moved forward, It passes through the stitch inheritance passage on the left and right sides opposite to that in FIG. 1 (in this case, there is no knitting needle at the i-needle position, so stitch transfer is not performed) and reaches the rear of the opened raising cam 15. Thereafter, the knitting needle 2 is moved forward by the tack cam 14, and when the butt of the knitting needle 2 reaches the central front guide cam 11, the thread end 4 of the thread end plate 45 is attached to the hook portion.
The knitting yarn T is supplied from 6 and reaches the rear of the knitting cam 9. Next, when the butt is pushed down by the needle selection cam 30 through the introduction slope 31 and the protrusion 32, the butt selectively receives the locking of the S plate (needle selection plate) and changes the height after passing through the protrusion 32. Generates a bat with height. Then, the high butt is moved backward by the needle selection and selection cam, and the low butt passes laterally and reaches the low butt release cam 36, where it is pressed down again and returns to the high butt after releasing the lock of the S plate. . Then, push the switching cam 21 forward against the spring and move it to Y3.
leading to. On the other hand, the knitting needles 2 that have been retreated by the needle selecting and selecting cam 33 rotate and push forward against the course switching cam 34 against the spring to reach X3. As described above, the butt of the knitting needle 2 is positioned at the knitting preparation position indicated by the two-dot chain line from X2 to X3 shown in FIG.
After the stockinette stitch is formed at the needle selection positions indicated by the two-dot chain lines from 2 to Y3, the needles are sorted and arranged, and the sliding movement of the carriage 4 is completed. In addition, regarding the correspondence of the S plate (needle selection plate) for needle selection at this time, the position of the punch card that instructs the correspondence of the S plate is set in the sliding direction of the carriage shown in Fig. 1 using a conventional known method. When changing from the sliding direction of the carriage shown in FIG. 5, the position changes to another pre-drilled arbitrary hole, depending on the arrangement of the holes (the presence or absence of holes). As described above (in correspondence with a needle selection instruction member such as a punch card, by sliding the main carriage 4, lace stitching can be easily performed by the action of the various cam groups arranged on the carriage and the stitch transfer auxiliary body A). In the case of lace knitting, such as once every three days or dice, it is sufficient to perform flat knitting after repeating the needle selection action and the stitch transfer action by reciprocating sliding of the carriage 4 a predetermined number of times.

It goes without saying that stockinette knitting may be knitted in one course or in three or more courses, depending on the silk fabric to be knitted.

Next, the two-color simultaneous knitting will be explained with reference to FIG. A knitting auxiliary body is fixed in advance to the front side of the carriage 4 in place of the transfer auxiliary body A by tightening the screws 41, and the butts of the knitting needles 2 in the knitting section are adjusted according to the pattern of the pattern. The needles are sorted into knitting preparation position V1 and needle selection position W1. After that, the colored thread T is attached to the front thread opening 63 of the thread opening plate 62.
2, the base thread T1 is inserted through the rear thread opening 64, and the cams on the lower surface of the carriage are arranged as shown in FIG. By sliding the carriage 4 in this state into the knitting section, the butt of the knitting needle 2 at the knitting needle position W1 at the needle selection position W1 once passes through the stitch succession passage, and then passes through the passage formed by the front partition wall 7 and the middle partition wall lO. Immediately after passing through the hook by pressing down the one-way spring 17, the colored yarn T2 is supplied into the hook and stitch knitting is performed. On the other hand, the butts of the knitting needles 2 at the knitting preparation position ■1 continue straight ahead, are moved forward by the raising cam 15 and the knitting cam 9, are guided by the front swinging cam 18 through the rear of the intermediate partition wall 10, and are guided to the center front. This leads to a passage formed by the rear of the cam 11 and the front edge of the central guide cam 12. Then, the ground yarn T1 is supplied to the hook, and stitches are knitted together by the knitting cam 9. Thereafter, both knitting needles 2 are introduced into the needle selection device section by the needle selection and selection cam 30, and then subjected to the action of the S plate according to the arrangement of the holes provided on the punch card V2. It is derived to the position of W2. Knitting from the next course onwards is performed in the same way by sliding the carriage 4 starting from each passage of ■2 and W2, and is led out of the carriage 4 to the knitting preparation position and needle selection position, and this process is repeated. Organize by.

Next, the tuck section will be explained with reference to FIG. In this case, the knitting yarn T is inserted only through the rear yarn opening 64, and the cams on the lower surface of the carriage 4 are arranged as shown in FIG. The butts of the knitting needles 2 within the embroidery section pressure are sorted into a knitting preparation position R1 and a needle selection position S1 according to the pattern of the pattern. By sliding the carriage 4 into the knitting section, the knitting needles 2 at the needle selection position S1 pass through the stitch succession passage, pass through the path switching cam 26, pass through the auxiliary switching cam 16, and then move to the central guide cam 1.
The knitting yarn T is supplied to the hook of the knitting needle 2 and knits a stitch.

On the other hand, the knitting needles at the knitting preparation position R1 continue straight and reach the tuck cam 14, and the butt moves forward and the knitting yarn T is fed into the hook at the front edge of the central guide cam 12. (Stitches are not knitted) After this, the knitting needles 20 butts are introduced into the needle selection device by the needle selection cam 30 and R2,
It is derived in S2. For knitting from the next course onward, it is sufficient to repeat the needle selection action and the sliding movement of the carriage.

Next, the sliding perspective will be explained with reference to FIG. In advance,
At least two different colors of knitting yarns T are prepared, and the knitting yarn T of the -color is inserted into the rear yarn opening 64, and the cams on the lower surface of the carriage are arranged only in the tuck cam 14 in the case of the above-mentioned tuck knitting. Position the arrangement forward. By sliding the carriage 4 in this state to the selected knitting section, the knitting needles 2 at the needle selection position P1 receive the knitting yarn T from the yarn port 64 through the stitch succession passage to form eyelet knitting. On the other hand, since the knitting needles 2 at the knitting preparation position Q1 are guided to the non-knitting path from beginning to end, the knitting yarn T is not supplied, let alone stitch knitting. After this, all the butts of the knitting needles 2 are introduced into the needle selection device by the needle selection cam, and the butts of the knitting needles 2, which were at the needle selection position P1, are moved to the knitting preparation position Q2 according to the hole pattern of the punch card. The butt of knitting needle 2, which was Q1, is selected and derived at needle selection position P2 in a negative/positive relationship, respectively. Thereafter, the knitting yarn T is replaced with another knitting yarn T, and in this state, the carriage 4 is turned back and slid to perform knitting in the same manner as the previous course. Next, stockinette knitting when using knitting auxiliary bodies will be explained. This is carried out by placing the cams on the lower surface of the carriage in the state shown in FIG. 9, inserting the knitting yarn T only through the rear yarn opening 64, and sliding the carriage 4 in this state.

At this time, since the tips of the left and right needle selection and selection cams are rotated forward and opened, the knitting needles 2 are not introduced into the needle selection device by the movement of the carriage, and needle selection is not performed. As described above, in the present invention, in particular, a central front guide cam is provided at the left and right center of the lower surface of the carriage, and behind the central guide cam there is a forward position where the central guide cam overlaps the central guide cam, and a rear edge of the central front guide cam when the central guide cam is further retreated. A width is provided between the front edge of the center guide cam and the front edge of the central guide cam to allow the butt of the knitting needle to pass through. The hook portion of the knitting needle at this position can be supplied with knitting yarn by the yarn opening of the yarn opening plate, and various cams such as a tuck cam pivotally supported by the central guide cam and a movable retracting cam can also be arranged. Outside the left and right sides of the various cams (l
A carriage configuration was adopted in which a passage for stitch transfer and a passage for stitch succession were provided, and a needle selection device was provided behind each of these passages. On the front side of this carriage, there is a knitting auxiliary body that has both front and rear yarn openings for supplying knitting yarn to the hooks of each knitting needle separately, and a knitting fabric presser member that prevents the knitted fabric from advancing, and a knitting auxiliary body that is guided to the stitch transfer path. and a transfer auxiliary body having a stitch passing device for passing the stitches suspended from the knitting needles to the hooks of the specific knitting needles in the stitch succession path, each of which is supported separately so as to be interchangeable. . Therefore, by replacing the transfer auxiliary body and the knitting auxiliary body as appropriate and attaching the carriage, lace knitting and pattern knitting such as two-color simultaneous knitting can be performed using a needle selection support member such as a punch card. Knitting can be easily carried out by selecting needles by
