Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for forming a widening stitch in a process in which a knitted fabric knitted on both front and rear needle beds is knitted on a tubular knitted fabric continuous at its ends. Regarding the organization method.

[0002]

2. Description of the Related Art Recently, the left and right sleeves and the body are knitted in advance as a tubular knitted fabric, and the knitting width is changed to form a knitted fabric having a desired shape. Various knitting methods for knitting a knitted fabric having a shape close to a finished product on a knitting machine by knitting while connecting are being studied. As a means for forming a knitted fabric into a desired shape, widening stitch knitting for increasing the knitting width is generally performed by forming a new stitch on an empty needle located outside the knitting width of the knitted fabric. There is. However, since the widening stitch is newly formed on the empty needle that does not hold the stitch, the stitch formed by the widening stitch has less tightness than the normal stitch because the stitches of the previous course do not exist. There is a problem that it becomes a stitch and a hole appears to be formed in the widening area. The knitted fabric knitted by the knitting method described above does not require sewing work for joining the parts to each other, and the post-treatment after the knitting is completed can be largely omitted. When a hole is formed in the formed portion, it appears on the surface of the knitted fabric as it is, which causes a decrease in commercial value. As a method for solving the above problem, for example, in Japanese Patent Publication No. 3-51810, when knitting a tubular knitted fabric, the needle loops of the stitches forming the widening stitch are twisted during knitting of the next course. The knitting method for knitting so that the length of the knitted stitches is shortened and the adjacent knitting stitches of the knitting stitches are pulled in to prevent holes from forming in the knitting stitches. Is disclosed.

[0003]

However, in the knitted fabric knitted by the above-mentioned knitting method for widening stitches, the widening stitches may be knitted depending on the kind of knitting yarn used for knitting and the knitting conditions such as the size of stitches to be formed. Holes may occur at the formation site. In view of the above problems, the present invention is a method for forming widening stitches in the process of performing cylindrical knitting, and it is possible to form a clean widening stitch forming portion without forming a hole in the widening stitch forming portion. It is an object to disclose a new widening stitch knitting method.

[0004]

In order to solve the above-mentioned problems, in the widening stitch knitting method in the tubular knitting of the present invention,
Using a knitting machine that is arranged in at least a pair of front and rear, and one or both needle beds are configured to be slidable left and right,
In the first course, the knitting yarn is supplied to the knitting needle that holds the stitches of the first knitted fabric to knit the first knitted fabric, and the stitches that are the side edges of the first knitted fabric are locked. The knitting yarn is hooked on an empty needle located in the forward direction of the yarn feeder on the needle bed facing the existing needle bed, and the yarn feeder is reversed in the second course to make the same first knitted fabric as in the previous course. Knitting, and then, in the third course, the yarn feeder is reversed again, and the knitting yarn is supplied to the knitting needle holding the stitches of the second knitted fabric to knit the second knitted fabric and The knitting yarn is hooked on an empty needle located forward in the traveling direction of the yarn feeding port beyond the empty needle that hooked the knitting yarn on the course, and the yarn feeding port is reversed on the fourth course to make the same second knitting as on the previous course. Knitting the ground, and then hooking the empty needle knitted on the empty needle in the first course. To Transfer eyes to the soil of the knitting needle. As a result, the stitches forming the first knitted fabric and the stitches forming the second knitted fabric cross each other, and the front side knitted fabric and the back side knitted fabric form a tubular knitted fabric that is continuous at its ends. The stitches forming the first knitted fabric and the stitches forming the second knitted fabric are attracted to each other, and the intersecting stitches close the holes. At the place where the widening stitch is formed, the yarn feeder is reversed and the knitted fabric on the same side is
Since the course is knitted continuously, the widening stitches formed at the widening stitch knitting points are formed as twisted stitches, and the stitches around the widening stitch formation points are prevented from forming pull-in holes due to short stitches. .

The empty needle that hooks the knitting yarn in the third course is a knitting needle on the same needle bed as the needle bed on which the stitches that are the side edges of the second knitted fabric are locked.

Further, the empty needle hooking the knitting yarn in the third course is a knitting needle on a needle bed different from the needle bed on which the stitches which are the side edges of the second knitted fabric are locked, and When the stitches forming the first knitted fabric are transferred, at the same time, the stitches forming the second knitted fabric are also transferred to the knitting needles of the opposing needle bed. As a result, the stitches forming the widening stitches on both sides become short twisted stitches, pulling in the stitches around the widening stitch formation portion, and reliably preventing holes from being formed in the widening stitch formation location. .

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings. In actual knitting, a large number of knitting needles are used for knitting, but here, for convenience of explanation, the number of needles used for knitting will be described as being smaller than the actual number.
1 to 4, FB indicates a front bed, BB indicates a rear bed, and arrows in the left and right directions in the drawings indicate a moving direction of the yarn feeder 1.
The up and down arrows indicate the transfer direction. In this embodiment, a pair of front and rear needle beds is provided, and a knitting needle is generally configured to be slidable forward and backward by a knitting cam and a transfer cam provided on a carriage (not shown) that slides left and right on the needle bed. Using a flat knitting machine, the odd-numbered knitting needles (indicated by capital letters of the alphabet) on the front and rear needle beds are used for knitting the front knitting fabric, and the even-numbered knitting needles (indicated by lower case letters of the alphabet) are knitting for the rear knitting fabric. An example will be described in which knitting is performed by using the above.

First, as shown in FIG. 1, in the course 1, the knitting yarns are supplied to the knitting needles A, B, C, D of the front bed FB to knit the front side knitted fabric, and then in the course 2, the yarn feeder 1 is reversed. The knitting yarn is supplied to the knitting needles d, c, b, a of the rear bed BB to knit the rear knitted fabric. Cylindrical knitted fabric in which the front side knitted fabric and the back side knitted fabric are continuous at their ends is formed by repeating the knitting shown in the course 1 and the course 2 by annularly supplying the knitting yarns to the knitting needles of the front and rear needle beds. To be done. Next, a widening stitch is formed on the knitting needle E of the front bed FB and the knitting needle e of the rear bed BB, and knitting is performed to increase the knitting widths of the front knitted fabric and the back knitted fabric by one stitch. First, in course 3, the knitting needles A, B, C, D of the front bed FB are supplied with knitting yarns to form stitches, and knitting needles E of the rear bed BB are knitted to form widening stitches on the front side knitted fabric. Hook the knitting yarn. At this time, knitting needle E
Since there is no stitch in the previous course, the supplied knitting yarn does not form a stitch and is in a state called a stitch of an empty needle knit locked in the hook of the knitting needle. Next, in the course 4, after reversing the yarn feeder, the knitting yarns are again supplied to the knitting needles D, C, B and A of the same front bed FB to form stitches. At this time, the stitches of the empty needle knit locked to the knitting needle E of the rear bed are in a twisted state. Next course 5
After reversing the yarn feeder, knitting needles a and b of the rear bed BB
The knitting yarn is supplied to c and d to knit the rear knitted fabric, and as knitting for forming the widening stitches on the rear knitted fabric, the knitting yarn is hooked in the course 1 and is passed over the knitting needle E to be knitted. The knitting yarn is supplied to the knitting needle e of the bed BB to hook the knitting yarn. At this time, since the knitting needle e does not have the previous course like the knitting needle E, the knitting yarn is in a state of being locked by the hook of the knitting needle. Next, in course 6, the yarn feeder 1 is reversed and again,
A knitting yarn is supplied to the knitting needles d, c, b, a of the rear bed BB to form stitches. At this time, the stitch of the empty needle knit of the knitting needle e of the rear bed BB is also twisted in the same manner as the stitch of the knitting needle E of the rear bed BB. Next, in course 7 shown in FIG.
The stitches of the empty needle knit, which are in a state of being locked by the knitting needles E of the rear bed BB, are transferred to the knitting needles E of the front bed FB, over the knitting yarns that are extending between the knitting needles d and e of the rear bed. As a result, the stitches of the empty needle knit of the knitting needle E of the rear bed BB that have been twisted are transferred to the knitting needles of the front bed FB.
With the above, one stitch each for the front knitted fabric and the back knitted fabric is completed.

Similarly, a widening stitch is also formed on the knitting needle F of the front bed FB and the knitting needle f of the rear bed BB. In the course 8, the knitting yarns are supplied to the knitting needles A, B, C, D of the front bed FB and the knitting needle E holding the stitches of the newly formed empty needle knit to form the stitches of the next course, and the front side As the knitting for forming the widening stitch in the knitted fabric, the knitting yarn is supplied to the knitting needle F of the rear bed BB to form the knitting stitch of the empty needle knit. As a result, the knitting yarn supplied to the knitting needle E of the front bed FB is held by the stitches of the empty needle knit formed in the previous course and forms a normal stitch. Next, in the course 9, the yarn feeder is reversed and the knitting yarns are supplied to the knitting needles E, D, C, B, A of the same front bed FB to form stitches. Next, in the course 10, after the yarn feeder is reversed, the knitting needles a, b, c, d of the rear bed BB and the stitches of the empty needle knit are held and the knitting needle e of the rear bed BB is held.
The knitting yarn is supplied to form the stitches of the next course,
As a knitting for forming a widening stitch on the back side knitted fabric, a knitting yarn is also supplied to the knitting needle f to form a stitch of an empty needle knit. As a result, after the stitches of the empty needle knit are locked, the normal stitches are locked on the knitting needle e of the bed BB. Next, in the course 11, the yarn feeder is reversed and the knitting yarns are supplied to the knitting needles e, d, c, b, a of the rear bed BB to form stitches. Next, in the course 12, the stitches of the empty needle knit, which have been locked to the knitting needles F of the rear bed BB, cross over the knitting yarns between the knitting needles e and f of the rear bed and the knitting needles F of the front bed FB.
Transfer to Thereby, from the state shown in FIG.
2 in each of front bed FB and rear bed BB
The formation of widening stitches is completed.

The knitted fabric having the widening stitch formed by the above-mentioned widening stitch knitting method is knitting needle E of the rear bed in the course 7 (12).
By transferring the stitches of the empty needle knit that have been held in (F) to the front bed over the knitting yarns between the knitting needles d (e) and e (f) of the rear bed BB, the front knitting is performed. The stitches of the empty needle knit forming the background and the stitches of the empty needle knit forming the back side knitted fabric intersect. Then, by forming the stitches of the next course on the knitting needles E of the front bed FB and the knitting needles e of the rear bed BB which hold the stitches of the empty needle knit in the courses 8 and 9, the knitting needles E of the front bed FB are formed. The formed stitches and the stitches formed on the knitting needle e of the rear bed BB are held in a state of intersecting each other. Thus, in the tubular knitted fabric in which the widening stitch is formed by the present invention, the stitches forming the front side knitted fabric and the stitches forming the rear side knitted fabric cross each other at the widening stitch forming location, and the state in which they are drawn to each other Therefore, the crossed stitches are in a state of closing the hole, and it is possible to form a clean widening area. In addition, since the yarn feeder is reversed at the place where the widening stitch is formed and the knitted fabric on the same side is knitted continuously for two courses, the widening stitch becomes a twisted state, so the stitch length is short. The stitch around the widening area is pulled in to prevent a hole from being formed in the widening area.

In the above embodiment, only the stitches forming the front side knitted fabric were formed by the knitting needles on the opposite needle beds.
As shown in course 1 to course 3 in FIG. 3 following course 4 in FIG. 1, the widening stitches forming the rear knitted fabric are attached to the front bed F.
The stitches of the empty needle knit formed by the knitting needle e of B and locked to the knitting needle E of the rear bed BB as shown in FIG.
It is also possible to transfer to the knitting needle E of B and to transfer the stitch of the empty needle knit locked to the knitting needle e of the front bed FB to the knitting needle e of the rear bed BB. In this case,
Since the stitch transferred to the knitting needle e of the rear bed BB also becomes a twisted stitch, it is possible to reliably prevent a hole from being formed in the widening stitch formation portion.

In the above-mentioned embodiment, only the knitting for forming the widening stitch is explained. However, as shown in the course 1 and the course 2 in the course where the widening stitch is not performed, the stitches of the front and rear needle beds are locked. The knitting may be performed by supplying the knitting yarn in an annular shape to the knitting needle. Further, in the above-mentioned embodiment, the case of using the flat knitting machine having only the front and rear needle beds is described as an example, but a four-bed horizontal bed having upper needle beds on the front and rear needle beds, respectively. The present invention can also be implemented in a knitting machine or the like. In this case, as shown in FIG. 4, the knitting needles A, B, C, D, E, and F of the front bed FB in FIG.

The knitting needles of the rear lower bed BD may be substituted for e and f to perform knitting (courses 1 to 5 in FIG. 4 correspond to courses 3 to 7 in FIG. 1).

[0013]

The knitted fabric knitted by the widening stitch knitting method in the tubular knitting of the present invention has the stitches of the empty needle knit formed as the widening stitches constituting the first knitted fabric and the second knitted fabric. The stitches of the empty needle knit that are formed as the widening stitches that form the crossover state are intersected, and the front knitted fabric and the back knitted fabric become a tubular knitted fabric that is continuous at their ends, and the first knitted fabric is When the stitches forming the second stitch and the stitches forming the second knit fabric are attracted to each other and the intersecting stitches close the holes, it is possible to form a clean widening area.

Further, since the stitches formed by the knitting needles of the opposing needle beds are transferred to the knitting needles of the opposing needle bed, the increased stitches are twisted, resulting in short stitch lengths and additional stitch formation. It is possible to pull in the stitches around the place and prevent a hole from being formed in the widening place.

Further, when the widening stitches of the front and rear knitted fabrics forming the tubular knitted fabric are formed on the needle beds facing each other and are transferred back, both knitted fabrics are formed. Since the stitches to be the widening stitches are twisted and have short lengths, it is possible to reliably pull in the stitches around the widening stitch forming portion and prevent holes from being formed in the widening stitch forming portion.
