Abstract

PROBLEM TO BE SOLVED: To provide a set-up method of a knitted fabric capable of knitting a set-up portion by split knitting using a flat knitting machine equipped with compound needles, each including a needle main body and a slider with two blades.SOLUTION: In the set-up method, split knitting is performed by forming new stitches a to c on knitting needles of one needle bed (BB) following target stitches A to C constituting a base end course formed on the one needle bed (BB) and by transferring the target stitches A to C to knitting needles of the other needle bed (FB). The target stitches A to C are transferred from the knitting needles of the FB to the knitting needles of the BB, and the new stitches a to c are transferred from the knitting needles of the BB to the knitting needles of the FB.

Description

  The present invention relates to a knitting fabric set-up method for knitting a set-up portion of a knitted fabric using a flat knitting machine including a compound needle having a needle body and a slider having two blades, and the set-up thereof. The present invention relates to a knitted fabric knitted by applying the method.

  Conventionally, a method for setting up a knitted fabric using a flat knitting machine including at least a pair of front and back needle beds is known. The simplest set-up method is a method of knitting a set-up portion of a knitted fabric by alternately supplying knitting yarn to the front and back needle beds. However, with this method, the crossover yarn between the front and back needle beds tends to be long, so that the set-up portion may become loose. In order to solve this problem, it has been proposed to knitting a set-up part using a split increase (see, for example, Patent Document 1).

  In order to knitting the set-up portion by using the split increase, first, the proximal course serving as the proximal end is knitted on one of the front and rear needle beds. Then, while transferring the stitch (target stitch) of the base course to the knitting needle of the other needle bed, a new knitting yarn is fed and the new stitch is pulled out from the stitch, and the knitting needle of one needle bed is pulled out. Forming on the knitting needle in which the target stitch to be transferred was originally locked is performed from one end side to the other end side in the knitting width direction. As shown in FIG. 4, the set-up portion knitted in such a manner becomes a set-up portion in which the sinker loops of the stitches locked to the front and back needle beds are intertwined with each other. In this set-up portion, the yarn length connecting the stitches does not become unnecessarily long, so that the set-up portion is tightened.

JP-A-4-73245

  However, the set-up method using the additional increase shown in Patent Document 1 is an effective method when the knitting needle of the flat knitting machine is a latch needle, and the knitting needle of the flat knitting machine is connected between the needle body and the needle body. This is an inappropriate method in the case of a compound needle (for example, see Japanese Patent No. 2917146) having a slider having two blades for opening and closing the hook. If the set-up method of Patent Document 1 is performed on a flat knitting machine having a compound needle, the stitches of the base course and the new stitches are not entangled as shown in FIG. The set-up part cannot be knitted. Needless to say, when the same procedure as in Patent Document 1 is followed, the composite needle cannot form the same set-up portion as in FIG. 4, and it does not mean that the composite fabric cannot be knitted.

  The above-mentioned problem is caused by the difference in structure for transferring stitches between opposing needle beds between a latch needle and a compound needle having a slider having two blades. In the case of the latch needle, since the blades on the side surface of the latch needle are used when transferring the stitches, the latch needles of the opposing needle beds are slightly shifted in the longitudinal direction of the needle bed. On the other hand, in the case of a compound needle having a slider with two blades, the configuration is such that the stitch held by the tongue at the tip of the blade at the mouth side of the blade is picked up by a hook of the compound needle facing the tongue. The hooks of the compound needles of the needle bed to be moved are not displaced in the longitudinal direction of the needle bed.

  As described above, it is a flat knitting machine using a compound needle having a structure different from that of the latch needle, and connects the knitting yarn that connects the stitches locked to the front needle bed and the stitches locked to the back needle bed. In order to knit the set-up part formed by entanglement with the knitting yarn, a completely new idea is required.

  The present invention has been made in view of the above circumstances, and one of its purposes is by using a flat knitting machine having a compound needle having a needle body and a slider having two blades, and by increasing the rate. An object of the present invention is to provide a knitting fabric setting method capable of knitting a set up portion, and a knitted fabric having a set up portion knitted by applying the method.

  The knitting method of the knitted fabric of the present invention is formed on one of the front and back needle beds using a flat knitting machine that includes at least a pair of front and back needle beds and can transfer stitches between the front and back needle beds. While forming a new stitch following the target stitch constituting the base course on the knitting needle of the one needle bed, setting up the knitted fabric by increasing the rate of transferring the target stitch to the knitting needle of the other needle bed This is a method for setting up a knitted fabric for knitting a part. In the knitting method of the knitted fabric of the present invention, the target stitch is transferred from the knitting needle of the other needle bed to the knitting needle of the one needle bed, and the new stitch is transferred from the knitting needle of the one needle bed to the other knitting needle. By transferring to the knitting needles of the needle bed, the target stitches and the new stitches in the opposing direction of the needle bed are replaced from the initial locking positions, and the target stitches are replaced by these locking positions. And the new stitch form the set-up portion. The knitting needle provided in the needle bed of the flat knitting machine used in the knitting method of the knitted fabric of the present invention is a composite needle having a needle body and a slider having two blades.

  An outline of the method for setting up the knitted fabric of the present invention will be briefly described with reference to FIG. In addition, the short line in FIG. 1 shows the knitting needle of the front needle bed (hereinafter referred to as FB) or the rear needle bed (hereinafter referred to as BB).

  First, FIG. 1A shows a state in which the stitches of the base end course (target stitches A to C) formed following the stitches formed by the drawn yarn indicated by dotted lines are locked to the knitting needles of BB. . When the target stitches A to C are split, the target stitches A to C move to the knitting needles of the FB, and the new stitches a to c are locked to the knitting needles of the BB (FIG. 1 ( B)). In this state, the split stitches are increased using the compound needle, so that the knitting yarns of the target stitches A to C and the knitting yarns of the new stitches a to c are not intertwined. Therefore, in the set-up method of the knitted fabric of the present invention, the target stitches A to C are transferred from the FB to the BB, and the new stitches a to c are transferred from the BB to the FB (see FIG. 1C). As shown in FIG. 1C, the knitting yarns of the target stitches A to C and the new stitches a to c are obtained by exchanging the locking positions of the target stitches A to C and the new stitches a to c in the opposing direction of the FB and BB. The knitting yarn is intertwined.

  As one form of the set-up method of the knitted fabric of the present invention, it is preferable that after all the new stitches are formed, the locking positions of the target stitches and the new stitches are switched.

  As one form of the set-up method of the knitted fabric of the present invention, the flat knitting machine is a four-bed flat knitting machine provided with a pair of front and back needle beds further facing above the pair of front and back needle beds facing each other, and When the base course is knitted with total needles, the engagement positions of the odd-numbered target stitches and the new stitches are changed from one end side in the longitudinal direction of the needle bed, and the even-numbered ones are counted from the one end side. Preferably, the target stitch and the replacement position of the new stitch are changed separately. The proximal course knitted with total needle is a proximal course knitted in a state in which no empty needle is provided between adjacent target stitches in the proximal course.

If the engagement positions of the target stitch and the new stitch are switched, it is preferable to perform the replacement according to the following steps α to δ if the odd stitch is replaced with the even stitch. As a premise of steps α to δ, one of the stitch group composed of the target stitches and the stitch group composed of the new stitches is a first stitch group, and the other is a second stitch group.
[Step α]... The 4n + 1 (4n + 2) stitch of the first stitch group is deposited on the upper needle bed facing the needle bed where the stitch is locked, and the 4n + 3 ( The 4n + 4th stitch is deposited on the upper needle bed facing the needle bed on which the stitch is locked.
[Step β]... 4n + 3 (4n + 4) stitch of the first stitch group and 4n + 1 (4n + 2) stitch of the second stitch group are passed through the empty needles formed in the step α. The stitches are transferred to the upper needle bed on the same side as the needle bed to be locked.
[Step γ] The stitches deposited in the step α are transferred to the empty needle formed in the step β via the empty needle formed in the step α.
[Step δ] The stitches deposited in the step β are transferred to the empty needle formed in the step α.

  An outline of the set-up method of the knitted fabric of the present invention including the steps α to δ will be briefly described with reference to FIG. In FIG. 2, FD is a lower front needle bed, BD is a lower rear needle bed, FU is an upper front needle bed, and BU is an upper rear needle bed. In the description using FIG. 2, the new stitches a to c are the first stitch group, the target stitches A to C are the second stitch group, and the first (4n + 1; n = 0) new stitch a from the left side of the page. Only the movement of the target stitch A will be described as an example.

  First, in the process α shown in FIG. 2A, the new stitch a locked to the BD is deposited in the FU that is the upper needle bed facing the BD. Next, in the process β shown in FIG. 2 (B), the target stitch A to be locked to the FD is passed through the BD empty needle formed in the process α, and is the upper needle bed on the same side as the FD. Move to. Then, in step γ shown in FIG. 2C, the new stitch a stored in FU is passed through the BD empty needle formed in step α to the FD empty needle formed in step β. Transfer. Finally, in the process δ shown in FIG. 2D, the target stitch A that has been deposited with the FU is transferred to the blank needle of the BD formed by the process α. Here, although not illustrated in FIG. 2, for the 4n + 3rd stitch (the third stitches C and c from the left side of the drawing) defined in the steps α to δ, the stitch A is sandwiched by the dotted line that is the boundary between the front and back needle beds. , A and the movement of line symmetry.

  On the other hand, the knitted fabric of the present invention includes at least a pair of front and back needle beds in which a plurality of composite needles each having a needle body and a slider having two blades are arranged, and stitches can be transferred between the front and back needle beds. A knitted fabric including a set-up portion knitted using a flat knitting machine. The set-up portion of the knitted fabric of the present invention is knitted by the above-described knitting method of the knitted fabric of the present invention.
