8), after the secondary needle 4 is rotated and both needles 4 and 63 are combined, the latch engagement plate 78 is raised and both needles 4 and 63 are moved rearward in the combined state,
The stitches on the main needle 4 are transferred to the sub needle 63 (the third
8 Figure 6). The latch 4c of the main hand 4 is attracted to the permanent magnet 80 and held in an upright position. Thereafter, the sub needle 63 enters the needle groove 2 of the needle bed 1 and the latch removal operation is performed, and the latch engagement plate 7
8 is lowered to prevent the latch 63b of the secondary needle 63 from rotating in the closing direction (FIG. 38). Thereafter, the thread opening 76 is moved from the left side to the right side of the secondary needle 63, the knitting yarn Y is supplied to the secondary needle 63, the latch engagement plate 78 is raised, and the secondary needle 63 is moved to the knockover position. A new stitch is then formed using the secondary needle 63 (FIG. 38, 9 and 10). Subsequently, the latch engagement plate 78 is lowered and the sub-needle 63 is moved up and down, and then the sub-needle 63 is removed (FIGS. 12-14). Then, both needles 4, 63 are moved forward with the two needles 4, 63 being combined again, and the stitches on the secondary needle 63 are transferred onto the main needle 4 (Fig. 38, 15), and the stitches on the secondary needle 63 are transferred onto the main needle 4 (Fig. 4 and 63 are released, the main needle 4 moves rearward, and a back stitch is formed on the hook 4b of the main needle 4.

Knitting with end needles at the left end of the main needle 4 in a predetermined knitting stage
In other words, when performing a lay-down knitting using the main needle 4 located at the uppermost position in Fig. 39 1a, the second
As shown in FIG. 6, unlike when performing the back stitch, both electromagnets S2 and S8 are not excited. Therefore, as shown in FIG. 25b, the electromagnets S1 and S2
Based on the selective excitation of the armature A1 is disposed in the disengaged position and the armature A2 is disposed in the engaged position,
The cam contact pin 147a of the secondary needle actuating lever 147 is placed in the intermediate position shown in FIG. Further, as shown in FIG. 20b, based on the selective excitation of the electromagnets S7 and S8, the armature A7 is placed in the disengaged position.
The armature A8 is placed in the engagement position and the feed switching plate 93 is placed in the neutral position.

When the drive cam body 122 is rotated in this state,
As shown in FIGS. 19 and 20b, even if the feed plate 101 is moved back and forth according to the cam shape of the tenth drive cam 170, each ratchet wheel 90, 91
is not rotated, therefore, FIG.
As can be seen by contrasting FIGS. 1a and 2a and 1a and 2a of FIG. 38, no feed is applied to the carriage 8. Moreover, as shown in FIGS. 14 and 22,
The cam contact pin 14 of the secondary needle operating lever 147 is based on the cam shapes of the fourth and fifth drive cams 143 and 144.
The sub needle 63 is reciprocated back and forth via the needle 7a. Therefore, unlike when performing the back stitch shown in FIG. 38, the secondary needle 63 is not moved back and forth in FIGS. 11 to 14 based on the cam shape of the fifth drive cam 144, and the A new stitch is never transferred to the main needle 4. Then, as shown in FIG. 39, 17a, the stitches are suspended from the sub needle 63 at a position facing the main needle 4 at the left end.

Knitting with the main needle following the end needle Next, when performing the knitting with the main needle 4 following the main needle 4 at the left end, as shown in FIG. Unlike the previous version, both electromagnets S7 and S8 are excited, and Fig. 20a,
As shown in Figure 21a, armatures A7 and A8
is placed in the disengaged position, and the feed switching plate 93 is placed in the left position. Therefore, the drive cam body 12
With the rotation of 2, as shown in Fig. 40 1 and 2,
Due to the action of the tenth drive cam 170, the carriage 8 is moved to the right by one pitch of the main needle 4. As described above, in FIGS. 11 to 14, the secondary needle 63 is not reciprocated back and forth, and therefore, a new stitch on the secondary needle 63 is not transferred to the main needle 4, and as shown in FIG. As shown in 17 and 17a, a stitch is suspended from the sub needle 63 at a position opposite to the main needle 4 following the end needle.

Therefore, by continuing to knit with the end needles and the main needle 4 following the end needles, it is possible to reduce the number of stitches by two stitches.

Lace section When performing lace section at a specified formation stage,
Figure 41 1-17, 1a, 2a, 9a, 10a,
17a, the second main needle 4 from the top and the sub-needle 63 cooperate to perform a knitting operation similar to the above-mentioned lie-down knitting, and then the knitting operation shown in FIGS.
As shown in 2a, 9a, 10a, and 17a, backstitch knitting operation is performed by cooperation of the third main needle 4 from the top and the sub needle 63. That is, first of all, as in the case of knitting with the main needle following the end needle, the selective excitation state of each electromagnet S1 to S8 is set, and the main needle 4 is set as shown in FIGS. 1 to 17 in FIG. After the stitches on the main needle 4 are transferred to the sub needle 63 (FIG. 41, 6), the sub needle 63 and the like are operated.
The knitting yarn Y is supplied from the yarn opening 76 to the needle 3 (FIG. 41, 9), and a new stitch is formed on the sub needle 63 (FIG. 41, 17).

Next, each electromagnet S1 corresponds to the back stitch operation.
~The selective excitation state of S8 is set, and FIG.
17, the main needle 4, the secondary needle 63, etc. are operated, and the stitch of the third main needle 4 from the top shown in FIG. 42 2a is transferred onto the secondary needle 63, and the secondary needle 6
Two stitches are suspended on 3 (FIG. 42, 6).
Thereafter, the yarn is fed to the secondary needle 63 to form a new stitch (FIG. 42, 9 and 10), and the stitch is transferred from the secondary needle 63 to the main needle 4 to form a new back stitch (FIG. 42, 17a). ). As a result, Figure 42 1
As shown in 7a, the stitch is removed from the second main needle 4 from the top, and the lace knitting is completed.

Knitting operation when the carriage moves to the left Now, when performing various knitting operations with the moving direction of the drive cam 8 set to the left, as shown in FIG. ,S
7, the excitation state of S8 is reversed. For example, in order to change the moving direction of the carriage 8 from right to left when performing table stitching, electromagnet S7,
By switching S8 from the energized state to the de-energized state, as is clear from FIGS. 21a and 21b,
Each armature A7, A8 is switched from a non-engaged position to an engaged position, and the feed switching plate 93 is placed in the 20th position.
It is moved from the left position in Figure a to the right position in Figure 19. Furthermore, as the electromagnet S3 is switched from the non-excited state to the energized state, the armature A3 is switched from the engaged position to the non-engaged position, as shown in FIGS.
The cam contact pin 163b is switched from the upper position to the lower position. As shown in FIGS. 12 and 14, with this switching operation, the cam contact pin 1
63b separates from the large diameter portion 161a of the eighth drive cam 161 and is engaged with the tail portion 160c of the seventh drive cam 160. Then, the drive cam body 12
2, the cam contact pin 163b is introduced into the large diameter portion 160a of the seventh drive cam 160. Therefore, when feeding the yarn during surface knitting, regardless of the traveling direction of the carriage 8,
By the action of the seventh and eighth drive cams 160 and 161, the thread head 76 is moved from the side opposite to the direction of movement of the carriage 8 with respect to the main needle 4 toward the side in the direction of movement of the carriage 8 (see FIG. 34).

Effects As detailed above, the invention of this application is arranged such that the cam contact portion of the needle actuating body is movable to a plurality of different positions with respect to the drive cam, and the cam contact portion of the needle actuating body is moved to a plurality of different positions on the carriage in correspondence with the cam contact portion. is equipped with an electromagnet that is excited in accordance with an electric signal, and a control member is provided between the electromagnet and the cam contact part, and the control member and the cam contact part are capable of reciprocating within a certain range. By providing a switching member, it is possible to easily switch the arrangement of the cam contact part with respect to the drive cam according to a predetermined organization, and the configuration is simplified without requiring a complicated device to perform the switching operation. This has an excellent effect that not only can the switching operation be performed accurately, but also that the switching operation can be performed accurately without causing a shift in the switching timing.
