Description

  The present invention relates to a method for forming an increased stitch on the inner side of the knitting width direction end of the knitted fabric when the knitted fabric is knitted with a flat knitting machine, and a knitted fabric on which such an increased stitch is formed.

  In the process of knitting the knitted fabric with the flat knitting machine, in order to knitted the knitted fabric into a desired shape, the additional stitches and the reduced stitches are performed. Here, two methods are known as a method of forming the additional stitches. One is a method of increasing the knitting width by forming a new stitch on an empty needle positioned outside the stitch at the end in the knitting width direction of the front knitted fabric portion or the rear knitted fabric portion (hereinafter referred to as increasing outside). Called). The other is to move the plurality of wale stitches at the knitting width direction end of the knitted fabric to the outside of the knitting width to generate empty needles in the knitting area of the knitted fabric, and form new stitches on these empty needles This is a method of increasing the knitting width (hereinafter referred to as “internal increase”).

  As a knitting method for performing the outside increase, for example, Patent Document 1 discloses. The knitting method disclosed in Patent Document 1 increases the outside while knitting the knitted fabric into a tubular shape by double system knitting in which two yarn feeders are knitted while being shifted in the longitudinal direction of the needle bed. Is going.

  Here, in the case of increasing outside, a wale is newly formed at the end of the knitted fabric in the knitting width direction every time an increased stitch is formed, so that the edge of the knitted fabric becomes uneven and the appearance is not very beautiful. On the other hand, with the increase in the inside, a new wale is formed at a place other than the edge of the knitted fabric. Therefore, a series of wales appear at the edge of the knitted fabric, and the boundary between the front and rear knitted fabric portions. The wale that sandwiches the line can be arranged in parallel and in a beautiful state.

  However, in any of the above-described methods for forming an additional stitch, an additional stitch is formed by feeding yarn to an empty needle having no stitch of the previous course. Accordingly, the newly formed stitch is pulled up by the stitch of the next course at the increased stitch forming portion, and there is a problem that a large hole is generated at the increased stitch forming portion and the appearance is deteriorated.

  Therefore, in order to solve the problem of the vacancy, the present applicant has proposed a method of forming an increase by increasing the number of the holes formed at the formation of the increase inconspicuousness (see Patent Document 2). In this method of forming an additional stitch, first, of the first needle and the second needle that are arranged opposite to each other on the front and back needle beds, the stitch that is locked to the first needle is transferred to the second needle. However, following the stitch transferred to the first needle and transferred to the second needle, a new stitch is formed on the first needle. By forming a new stitch on the first needle, the stitch transferred to the second needle becomes an additional stitch. Then, by moving the needle bed laterally by racking, providing a blank needle next to the first needle, and then transferring the stitch transferred to the second needle to the blank needle, An additional stitch is formed on the side of the stitch locked to the needle. In this additional stitch forming method, an increased stitch is formed by using transfer between needles provided on different needle beds on the front and rear sides, and the first stitch is split into two to form an increased stitch. It becomes a state (hereinafter referred to as “increase”).

Japanese Patent No. 3122833 Japanese Examined Patent Publication No. 62-52063

  When forming an increased stitch by increasing the split, the increased stitch is held by the stitch of the previous course, and is not pulled up by the stitch of the next course. Therefore, a knitted fabric having an increased number of stitches can be knitted with a very small opening, and a knitted fabric having a beautiful appearance can be provided.

  However, when an additional stitch is formed by increasing the split, the stitch that has already been formed is divided into two to form a new stitch. Therefore, when using a yarn that is prone to yarn breakage and knitting at a small degree, the additional stitches are smaller than other loops, making it difficult to perform knitting such as transfer, and missing stitches may occur. There is a risk of doing. Furthermore, if the eyes become too small, the strain on the yarn increases.

  Therefore, the present invention is easy to knit, less burden on the yarn, and further, a method of forming an increased stitch that can make the hole formed at the increased stitch formation location inconspicuous, and a knitted fabric having the increased stitch knitted by the method. The purpose is to provide the earth.

  The knitting method of the knitted fabric of the present invention includes a flat knitting machine having at least a pair of front and back needle beds, at least one of the front and back needle beds being rackable to the left and right, and capable of transferring stitches between the front and back needle beds Is a method of forming an increase inward from the knitting width direction end portion of the knitted fabric, wherein the increase is formed by the following steps.

Step a in which the stitches already locked to the knitting needles forming the additional stitches are transferred to the empty needles of the opposing needle bed and the knitting needles forming the additional stitches are used as the empty needles a.
A knitting of the next course is performed from one end of the knitting region to the other end of the knitting area in a needle bed having knitting needles forming the additional stitches that are empty needles, and knitting is performed in the hooks of the knitting needles that form the additional stitches during the knitting. A step b of performing an empty needle knit for locking the yarn;
Step c of transferring the stitches locked to the needle on the knitting needle side adjacent to one of the knitting needles forming the additional stitch among the stitches knitted in Step b,
After the needle bed is racked so that the stitch transferred in Step c is separated from the stitch knitted in the empty needle, the stitch transferred in Step a and the stitch transferred in Step c are opposed to each other. Step d to move to the empty needle.

  In the method for forming an additional stitch according to the present invention, the stitch transferred in step a is locked among the stitches transferred in step d following step d of the method for forming the additional stitch. It is preferable to perform the step of knitting the next course from one end to the other end of the knitting region at least once while making a mistake with the knitting needle.

  In the method for forming an additional stitch according to the present invention, the next course is knitted from one end of the knitting region to the other end continuously between the stitches of the empty needle knit knitted in step b between step b and step c. It is preferable to organize so as to include a step of performing.

  In the method for forming an additional stitch according to the present invention, the above-described flat knitting machine further includes a first yarn feeder and a second yarn feeder, and knitting while performing double system knitting using these two yarn feeders. The present invention can also be applied to the case where an increased stitch is formed on the inner side of the end portion in the knitting width direction of the ground. When performing double system knitting, it is preferable to knit the knitted fabric in a cylindrical shape.

  By the way, when the knitted fabric is knitted by double system knitting, as shown in FIG. 9, the following second yarn feeder 5 is provided on the front side when viewed from the front side of the knitting machine, and the preceding first yarn feeder When 6 is provided on the back side and knitted into a cylindrical shape, there is a problem that two knitting yarns intersect at one of the end portions in the knitting width direction which is the reversal position in the traveling direction of the yarn feeder. At the intersection of the knitting yarns, the knitting yarn is pulled by the surrounding stitches, and a hole g as shown in FIG. 10 is generated at the boundary X between the front and rear knitted fabric portions. In Patent Document 1, knitting is performed so that the holes at the intersecting portions are not easily noticeable, but the holes are still not formed and the holes are still formed in the knitted fabric.

  Therefore, the method for forming an additional stitch according to the present invention is a front-rear boundary between the front knitted fabric portion and the rear knitted fabric portion when the increased stitch is formed while the knitted fabric is knitted into a tubular shape by double system knitting. It is preferable to form a boundary wale. This boundary wale is formed by continuously forming the stitches while twisting the stitches, and by winding and forming a knitting yarn different from the knitting yarn forming the twisted stitches. No holes are formed.

  By knitting the knitted fabric in which the increased stitches are formed on the inner side of the knitting width direction end of the knitted fabric by the above method, the knitted fabric that is already locked to the knitting needles to be formed with the increased stitches is deposited on the opposite needle bed. In the state where the knitting needle to be formed is a blank needle, the knitting yarn is locked in the hook of the blank needle, and the stitch is formed. In addition, the knitted fabric formed by the above method has a stitch that has been deposited on the opposing needle bed that is hidden between the increased stitch and the stitch adjacent to the increased stitch. A new stitch is formed following the stitch.

  It is preferable that the knitted fabric in which the increased stitches are formed inside the knitting width direction end portion of the knitted fabric of the present invention is a tubular knitted fabric.

  According to the knitting method of the knitted fabric of the present invention, with the stitches formed in advance on the knitting needles forming the additional stitches, the stitches are transferred to the opposite needle bed, and the stitches become empty needles. After forming an increased stitch on the knitting needle, the transferred stitch is returned to the next to the increased stitch. As a result, even if the holes are formed by the additional stitches, a part of the holes are blocked by the stitches returned by the transfer, so that the holes generated at the additional stitch forming portions are conspicuous. Can be difficult.

  When forming the additional stitches by the method of the present invention, the stitches that have already been formed are not divided into two to form the additional stitches. Even when knitting with, the additional stitches can be knitted easily and the burden on the yarn is small.

  Further, in the knitting following the step d, the next course is knitted from one end of the knitting region to the other end while making the knitting needle to which the stitch transferred at the step a is locked is missed. A new stitch that is continuous with the stitch transferred in step (b) is formed in the course following the course that forms a mistake. By the newly formed stitch, the stitch transferred at step a is pulled up, and the holes generated at the additional stitch forming portion can be made less noticeable.

  Further, when a new stitch is formed continuously from the stitch transferred in step a by knitting the next course in succession to the empty needle knit between step b and step c described above, The stitches transferred in step a can be pulled up to make the holes generated at the formation of additional stitches less noticeable.

  Moreover, according to the method of forming an additional stitch according to the present invention, when the additional stitch is formed while performing knitting with a double system, the knitting and transfer of two courses are performed while the carriage loaded with a plurality of knitting systems travels one course. It becomes possible. As a result, productivity can be improved while easily forming an increase in a large hole so as not to generate a large hole in an increase formation area.

  In the case of double system knitting, the knitted fabric is knitted into a cylindrical shape, thereby improving productivity. In addition, when knitting in a cylindrical shape with double system knitting, a boundary wale is formed as a front and rear boundary between the front knitted fabric portion and the rear knitted fabric portion, and this boundary wale is twisted while twisting the stitch. When the knitting yarn is wound around a twisted knitting yarn different from the knitting yarn forming the knitting yarn, the boundary wale does not cause a hole that has been generated conventionally. In addition, an appearance like a sewing stitch can be obtained by twisting and winding the knitting yarn, and a knitted fabric excellent in design can be produced.

  Next, preferred embodiments of the present invention will be described below in detail with reference to the drawings. This embodiment has a pair of front and back needle beds that extend in the left-right direction and face each other in the front-rear direction, the rear needle bed can be racked left and right, and the stitch transfer between the front and back needle beds is The knitted fabric is knitted using a possible four-bed flat knitting machine.

  In knitting the knitted fabric, the knitted fabric can be knitted using a two-bed flat knitting machine including a front needle bed and a rear needle bed. When a knitted fabric is knitted using a two-bed flat knitting machine, the knitted fabric is knitted in a state in which every other needle is provided. Further, when a two-bed flat knitting machine is used, a knitted fabric may be knitted by providing a transfer jack bed in which transfer jacks are arranged in a row above one or both of the front and back needle beds.

  The four-bed flat knitting machine includes an upper front needle bed and an upper rear needle bed in which a large number of knitting needles are arranged at the same pitch as the lower needle bed on the lower front needle bed and the lower rear needle bed. . Hereinafter, the lower front needle bed is simply referred to as FD, the lower rear needle bed as BD, the upper front needle bed as FU, and the upper rear needle bed as BU.

  In the present embodiment, the front body and the front knitted fabric portion of the left and right sleeves are knitted by the FD of the flat knitting machine having four beds, and the rear body and the rear knitted fabric portion of the left and right sleeves are knitted by the BD. I am doing so. The BU needle is used to transfer the stitches of the front body and the front knitted fabric portion of the sleeve. The FU needle is used to transfer stitches in the back body and the back knitted fabric portion of the sleeve.

  By using the above-mentioned FU and BU, it is possible to knitting a texture pattern in which front and back stitches such as lynx, garter, and rib are mixed, wrapping stitches, and stitching.

  The flat knitting machine used in the present embodiment further includes a second yarn feeder 5 slidably provided on a guide rail (not shown) located on the front side (front side) when viewed from the front side of the knitting machine, A first yarn feeder 6 slidably provided on a guide rail located on the side (rear side).

  In the flat knitting machine that performs the double system knitting according to the present embodiment, a carriage on which the cam system S2 and the cam system S3 used for knitting and the cam system S1 and the cam system S4 used for transferring are mounted is moved on the needle bed. Prepare. Hereinafter, the cam system S1, the cam system S2, the cam system S3, and the cam system S4 are simply referred to as S1, S2, S3, and S4. In the knitting process, the cam system from the leading side in the carriage traveling direction is always S1, S2, S3, S4.

  During one forward or backward movement of the carriage by these cam systems, knitting with the knitting yarn fed from the preceding first yarn feeder 6 and yarn fed from the subsequent second yarn feeder 5 are performed. Double system knitting is performed in which knitting with knitting yarn and transfer are performed.

  A sweater 1 knitted in this embodiment is a long-sleeved sweater 1 having a round neck, a body 2, a right sleeve 3, and a left sleeve 4, as shown in FIG. In this sweater 1, the body 2 is continuously knitted in a cylindrical shape at the front and back, and the left and right sleeves 3 and 4 are also knitted in a cylindrical shape. The body 2 and the sleeves 3 and 4 are knitted and joined to form one continuous cylinder. In the present embodiment, terms representing the body and the left and right of the sleeve, for example, the right and left of the right sleeve 3 and the left sleeve 4 are based on the wearer wearing the sweater 1.

  The left and right sleeves 3 and 4 are usually knitted with a knitting width gradually increased from the cuff side while knitting in a cylindrical shape. In order to increase the knitting width, in the present embodiment, the front knitted fabric portion and the back knitted fabric portion of the sleeves 3 and 4 are adjacent to the body 2 in the knitting width direction end portion, and the front and back knitted fabric portions An additional stitch is formed on the inner side of the fourth to fifth stitches from the front / rear boundary.

  Depending on the shape of the knitted fabric to be knitted, this additional stitch may be formed by one stitch every two courses, or by one stitch every four courses. 6 Each time a course is organized, one eye is formed at a time.

  In the sweater 1 of the present embodiment, the back body of the body 2, the back knitted fabric portion of the right sleeve 3 and the left sleeve 4 are knitted mainly using a BD in a full needle state without providing empty needles. The front body of the body 2 and the front knitted fabric portions of the right sleeve 3 and the left sleeve 4 are knitted mainly using the FD in a full needle state without providing empty needles.

  In the following, an embodiment of the method for forming an additional stitch according to the present invention will be described with reference to the loop diagram of FIG. 1 and the knitting process diagrams of FIGS. In the present embodiment, the knitting performed by the left and right sleeves 3 and 4 is the same as the knitting method except that the right and left sleeves 3 and 4 are reversed. Only the knitting in the case of forming will be described.

  The knitting structure of the body 2 and the sleeves 3 and 4 in the sweater 1 is plain knitted plain for convenience of explanation, and the hem part of the body 2 and the cuffs of the sleeves 3 and 4 are ribbed.

The knitted fabric loop diagram shown in FIG. 1 shows a state in which an increased stitch is formed on the front knitted fabric portion of the right sleeve 3. Alphabet H~K shown in FIG. 1 shows a needle F D. FIGS. 2 and 3 show a process chart in which an increased stitch is formed from a state in which a portion of the right sleeve 3 is knitted into a tubular shape by flat knitting.

  In the knitting process diagrams of FIGS. 2 and 3 and the knitting process diagram (FIG. 6) in the case of knitting the boundary wale described later, the number of stitches of the right sleeve 3 is the number used in the actual knitting for convenience of explanation. Less display. Alphabets A to R shown in FIG. 2 and FIG. 3 indicate FD, BD, FU, and BU needles arranged to face each other. In the knitting process diagram of FIG. 6, FU and BU are omitted. Further, the uppercase alphabets in the knitted fabric loop diagram correspond to the alphabets shown in the knitting process diagram. 2, 3, and 6, the leftmost numeral indicates the knitting block number.

  In each knitting block of FIGS. 2 and 3, the arrow in the rightmost column indicates the racking direction of the rear needle bed, and the number of pitches is indicated below the arrow. Furthermore, the arrow in the column adjacent to the left of the rightmost column indicates the knitting direction. In each knitting block in FIG. 6, the arrow in the rightmost column indicates the knitting direction.

  Step S shown in FIG. 2 shows a state before the formation of the additional stitch is started at the stage during the knitting of the right sleeve 3. Furthermore, in step S, the stitches are locked from the needles C to N of the FD and BD, and the right sleeve 3 is knitted in a cylindrical shape.

  The stitch locked to the FD is the stitch of the front knitted fabric portion of the right sleeve 3, and the stitch locked to the BD is the stitch of the rear knitted fabric portion of the right sleeve 3.

  The knitting block 1 shown in FIG. 2 moves the carriage to the left and first feeds the FD from the first yarn feeder 6 to knitting the front knitted fabric portion for one course in the preceding S2. Next, yarn is fed from the second yarn feeder 5 to the FD, and in the subsequent S3, the next course is knitted continuously with the stitch knitted in S2. Finally, in S4, among the stitches of the rear knitted fabric portion that has already been knitted, the stitches locked to the needles J of the BD are transferred to the needles J of the FU facing each other. By this transfer, the needle J of the BD becomes a blank needle.

  In the next knitting block 2, first, the BD is fed from the first yarn feeder 6 and the rear knitted fabric portion is knitted one course at the preceding S2. At this time, since the needle J of the BD is an empty needle, the knitting yarn is locked in the hook of the empty needle to perform empty needle knit. Next, yarn is fed from the second yarn feeder 5 to the BD, and in the subsequent S3, the next course is knitted continuously to the stitch knitted in S2. Finally, in S4, among the stitches of the rear knitted fabric portion knitted in S3, the four stitches locked to the BD needles K, L, M, N are opposed to the FU needles K, L, Move to M, N.

  In the next knitting block 3, after the rear needle bed is racked by one pitch to the left, first, the five stitches locked to the needles J, K, L, M, and N of the FU are opposed by the preceding S1. Transfer to BD needles K, L, M, N, O. By this transfer, the stitch transferred to the needle J of the FU by S4 of the knitting block 1 is locked to the needle K adjacent to the needle J of the BD on which the empty needle knit is performed, and the rear side Increased stitches are formed in the knitted fabric portion. Further, in S1 of the knitting block 3, the stitches of the front knitted fabric portion locked to the needle I of the FD are transferred to the BU needle J facing the BU.

  Similarly, in the knitting block 3, yarn is fed from the first yarn feeder 6 to the FD, and in the next S2, the front knitted fabric portion is knitted for one course. At this time, since the needle I of the FD is an empty needle, the knitting yarn is locked in the hook of the empty needle to perform the empty needle knit. Next, yarn is fed from the second yarn feeder 5 to the FD, and in the subsequent S3, the next course is knitted continuously with the stitch knitted in S2. Finally, in S4, among the stitches of the front knitted fabric portion knitted in S3, the BU needles K, L facing the four stitches locked to the needles J, K, L, M, N of the FD are opposed. , M, N, O.

  In the next knitting block 4 (see FIG. 3), after the rear needle bed is racked to the right by one pitch, first, it is locked to the BU needles J, K, L, M, N, and O by the preceding S1. The six stitches are transferred to the FD needles J, K, L, M, N, and O facing each other. By this transfer, the stitch transferred to the BU needle J by S1 of the knitting block 3 is locked to the needle J adjacent to the needle I of the FD on which the empty needle knit is performed, and the front knitting Increased eyes are formed in the ground.

  Similarly, in the knitting block 4, yarn is fed from the first yarn feeder 6 to the BD, and in the next S2, the rear knitted fabric portion is knitted for one course. At this time, the needle K of the BD makes a mistake. Next, the yarn is fed from the second yarn feeder 5 to the BD, and in the subsequent S3, the next course is knitted one course following the stitch knitted in S2. Also at this time, the BD needle K makes a mistake. Due to these mistakes, the stitches of the BD needle K remain engaged.

  In the next knitting block 5, first, the FD is fed from the first yarn feeder 6 and the front knitted fabric portion is knitted one course at the preceding S2. At this time, the needle J of the FD makes a mistake. Next, the yarn is fed from the second yarn feeder 5 to the FD, and in the subsequent S3, the next course is knitted one course following the stitch knitted in S2. At this time, the FD needle J makes a mistake. Due to these mistakes, the stitches remain locked on the needles J of the FD.

  In the next knitting block 6, first, the BD is fed from the first yarn feeder 6 and the rear knitted fabric portion is knitted one course at the preceding S2. Next, yarn is fed from the second yarn feeder 5 to the BD, and in the subsequent S3, the next course is knitted continuously to the stitch knitted in S2.

  In the next knitting block 7, first, the FD is fed from the first yarn feeder 6 and the front knitted fabric portion is knitted one course at the preceding S2. Next, yarn is fed from the second yarn feeder 5 to the FD, and in the subsequent S3, the next course is knitted continuously with the stitch knitted in S2.

  By knitting the knitted fabric as described above, an additional stitch as shown in FIG. 1 can be formed at a location where the additional stitch is formed near one end in the knitting width direction of the tubular knitted fabric. In the present embodiment, the stitches already locked to the knitting needles to be formed with the additional stitches are deposited on the needle bed facing the stitches. Next, even if a hole is formed in the area where the additional stitch is formed by knitting the additional needle forming knitting needle which has become an empty needle to form the additional stitch, the needle bed is formed so as to close the hole. The deposited stitch is returned to the original needle bed so as to be hidden between the increased stitch and the stitch adjacent to the increased stitch. Then, by forming a new stitch continuously with the submerged stitch, the submerged stitch is pulled up by the new stitch, and the hole at the increased stitch formation portion is reduced.

  In this embodiment, after making a mistake twice for a stitch that is hidden between the increased stitch and the stitch adjacent to the increased stitch, a new stitch that is continuous with the hidden stitch is formed. For this reason, the course on the fifth course is knitted from the course on which the submerged stitch is knitted while the submerged stitch is positioned on the same course as the course on the fourth course from the course on which the submerged stitch is knitted. The As a result, this submerged stitch is strongly pulled up by a new stitch on five courses following this stitch. As a result, it is possible to make the holes at the positions where the increased eyes are formed more inconspicuous. In the loop diagram of FIG. 1, the stitches hidden in order to make the knitting state easy to understand are formed long, but in practice, the hidden stitches are small like the image of the knitted fabric shown in FIG. 7. .

  As described above, in this embodiment, the double stitches are formed while the double system knitting is performed, so that the two courses can be knitted and transferred while the carriage travels one course. As a result, not only can the knitted fabric be formed so as not to generate a large hole at the additional stitch formation site, but it is not necessary to run the carriage only for transfer, and the productivity of the knitted fabric can be improved.

  In this embodiment, knitting is performed using two yarn feeders by double system knitting. However, when a yarn is fed from only one yarn feeder and knitted into a cylindrical shape, an additional stitch is formed in the same manner. Further, knitting that misses on the stitches for reducing the holes formed by the additional stitches can be performed. Furthermore, although this mistake was performed twice in the present embodiment, the mistake may be performed only once or may not be performed. Whether or not to make a mistake in this way, and the number of mistakes to be made when making a mistake, may be determined according to the type and material of the knitting yarn to be used. For example, if the knitting yarn has elasticity, there is no need to make a mistake. If the knitting yarn has low stretchability, the number of mistakes is increased, and the stitch is strongly pulled up by the upper stitch far from the hidden stitch.

  By the way, when a knitted fabric is knitted by double system knitting, both yarn feeders knive the tubular knitted fabric by feeding the needles on both front and rear needle beds in an annular shape. As a result, the knitting yarn fed from the preceding yarn feeder and the knitting yarn fed from the succeeding yarn feeder intersect each other at the knitting width direction end which is the reversal position of the yarn feeder in the traveling direction, As shown in FIG. 10, a hole g is formed in the boundary portion X between the front and rear knitted fabric portions.

  Therefore, in this embodiment, when forming an increased stitch while knitting in a cylindrical shape with double system knitting, the front and rear boundary portions of the front knitted fabric portion and the rear knitted fabric portion of the tubular knitted fabric are A boundary wale is formed as a boundary. The boundary wale is formed by forming a stitch while twisting and winding a knitting yarn different from the knitting yarn forming the twisted stitch around the twisted stitch.

  The boundary wale knitting method will be described with reference to FIGS. FIG. 4 shows a knitted fabric loop diagram on the body side, that is, on the inner side of the sleeve, in the boundary portion between the front knitted fabric portion FF and the rear knitted fabric portion BF of the right sleeve 3. In the present embodiment, the body side boundary portion of the right sleeve 3 is a side where two knitting yarns intersect in double system knitting. FIG. 5 shows a knitted fabric loop diagram on the opposite side of the body, that is, on the outer side of the sleeve, in the boundary portion between the front knitted fabric portion FF and the rear knitted fabric portion BF of the right sleeve 3. FIG. 6 shows a knitting process diagram for knitting the boundary wale.

  Alphabets L to N and B to D shown in FIGS. 4 and 5 indicate FD and BD needles. 4 and 5 indicates a boundary line between the front knitted fabric portion FF and the rear knitted fabric portion BF.

  Step S shown in FIG. 6 shows a state in which the stitches are locked to the needles C to N of the FD and BD, and the right sleeve 3 is knitted into a cylindrical shape during the knitting of the right sleeve 3. . In this knitting process diagram, in order to distinguish between the formation method of the increase eyes and the formation method of the boundary wale, the formation of the increase eyes is omitted. The stitch locked to the FD is the stitch of the front knitted fabric portion FF of the right sleeve 3, and the stitch locked to the BD is the stitch of the rear knitted fabric portion BF of the right sleeve 3.

  In the knitting block 1 of FIG. 6, the carriage moves to the left, and first, the yarn is fed from the first yarn feeder 6 to the FD, and the front knitted fabric portion FF is knitted one course at the preceding S2. Next, yarn is fed from the second yarn feeder 5 to the FD, and in the subsequent S3, the next course is knitted continuously with the stitch knitted in S2. In S3, the stitches at both ends in the knitting width direction form stitches one by one more than the number of stitches fed and knitted from the first yarn feeder 6 in S2. That is, stitches are also formed on the needle B and the needle O of the FD. Finally, in S4, among the stitches knitted in S3 of the front knitted fabric portion FF, the stitches locked to the needles O of the FD are transferred to the opposing needles O of the BD, and the needles B of the FD are engaged. The stitches that are stopped are transferred to the needle B of the BD facing the stitches. At this time, since the first yarn feeder 6 is arranged behind the second yarn feeder 5 in the stitch at the left end portion in FIG. 6, the stitch that is locked to the needle B of the FD is opposed to the BD. When the needle B is transferred, the knitting yarn fed from the second yarn feeder 5 goes over the knitting yarn fed from the first yarn feeder 6.

  In the next knitting block 2, first, the BD is fed from the first yarn feeder 6 and the rear knitted fabric portion is knitted one course in the preceding S2. At this time, a stitch is not formed on the needle B of the BD to which the stitch transferred at S4 of the knitting block 1 is locked, and a stitch is formed on the needle O of the BD. As a result of the knitting at S2, the stitches locked to the needle B of the BD are in a state where the knitting yarn fed from the first yarn feeder 6 is wound (knitting yarn a shown in the loop diagram of FIG. 5).

  Then, in the knitting block 2, the BD is fed from the second yarn feeder 5 to the BD, and in the subsequent S3, the next course is knitted continuously with the stitch knitted in S2. A stitch is formed on the needle B of the BD, and a stitch is not formed on the needle O of the BD. In the knitting in S3, the stitch transferred to S4 of the knitting block 1 and locked to the needle B of the BD is twisted (the stitch b shown in the loop diagram of FIG. 5). Further, a stitch is formed with the same knitting yarn (knitting yarn fed from the second yarn feeder 5) at the needle B continuously with the twisted stitch (the stitch c shown in the loop diagram of FIG. 5).

  In the knitting block 2, finally, in S4, the stitches of the BD needle O knitted by feeding from the first yarn feeder 6 in S2 are transferred to the opposing FD needle O, and in S3 the second yarn feeder The stitches of the needles B of the BD knitted by feeding from 5 are transferred to the needles B of the FD facing each other. By these transfers, the stitches locked to the needles B of the FD are twisted (the stitches c shown in the loop diagram of FIG. 5), and the stitches locked to the needles O are twisted. (The stitch e shown in the loop diagram of FIG. 4).

  The next knitting block 3 performs the same knitting as the knitting block 1. From the relationship of the knitting block 2, the state of the stitch formed at the end in the knitting width direction will be described. The knitting yarn is fed to the FD from the first yarn feeder 6 and the front knitted fabric portion FF is knitted one course at the preceding S2, but no stitches are formed on the needle O and the needle B of the FD. Therefore, a stitch is formed on the adjacent needle N following the stitch locked to the needle O formed in S2 of the knitting block 2. At this time, the knitting yarn fed from the second yarn feeder 5 is wound around the stitch locked by the needle O (knitting yarn d shown in the loop diagram of FIG. 4).

  In S3 of the knitting block 3, among the stitches knitted by being fed from the second yarn feeder 5, the stitch knitted by the FD needle O at the end in the knitting width direction is fed from the first yarn feeder 6. The stitches knitted with the knitting yarns are continuously formed, and the stitches knitted with the needle B are continuously formed with the stitches knitted with the knitting yarn fed from the same second yarn feeder 5.

  In S4 of the knitting block 3, transfer is made to the needles B and O of the BD that face the stitches locked to the needles B and O of the FD. At this time, the stitch locked to the needle O of the BD is twisted (the stitch f shown in the loop diagram of FIG. 4).

  By knitting the boundary wale in this way, this boundary wale was continuously knitted while twisting the stitches, and further, a knitting yarn different from the knitting yarn forming the twisted stitch was twisted. It will be in the state wound around the stitch. As a result, this boundary wale prevents the holes that were previously generated by the double system knitting from becoming vacant, and the appearance of a sewing stitch is obtained by twisting and winding of the knitting yarn. Can also knitting excellent knitted fabric. Furthermore, since the stitches of the boundary wale are twisted and further knitted with other knitting yarns, the boundary portion of the knitted fabric can be made difficult to stretch.

  The loop diagrams shown in FIGS. 4 and 5 express the boundary wale stitches at positions corresponding to the respective needles for convenience of explanation, but when the stitches actually become stable, the images in FIG. As shown, the stitches of the boundary wales extend straight in the waling direction.

  In the present embodiment, the right sleeve 3 is configured such that two knitting yarns intersect each other inside the sleeve. Therefore, the boundary wales of the present invention may not be formed on the outer side of the sleeve on the side where the yarn does not intersect by the conventional double system knitting, and the boundary wales may be formed only on the inner side of the sleeve.

  Furthermore, when performing double system knitting, the yarn feeder for feeding two knitting yarns is provided with the second yarn feeder 5 on the front side and the first yarn feeder 6 on the back side in this embodiment, The first yarn feeder 6 was always preceded. However, the knitting method of the present invention can also be applied to the case where the first yarn feeder 6 on the back side is preceded on the forward path and then the second yarn feeder 5 on the near side is preceded on the return path. Furthermore, the present invention can be applied to the case where four yarn feeders are arranged on different guide rails and knitting with two yarns while switching the yarn feeders, and two yarn feeders are arranged on the same guide rail. It can also be applied when organizing. When such a yarn feeder is arranged, the manner of occurrence of yarn crossing is different from that of the present embodiment. For example, yarn crossing occurs at the end opposite to this embodiment, or yarn is formed at both ends of the knitting width direction. However, the method for forming a boundary wale according to the present invention can appropriately cope with a different state of yarn crossing.

  Furthermore, when the knitting method of the present invention is performed by double system knitting, it can be applied not only to knitting a knitted fabric in a cylindrical shape but also to knitting a knitted fabric by molding knitting. In addition, the knitted fabric in which the increased stitches are formed inside the knitting width direction end of the knitted fabric of the present invention is not limited to a molded knitted fabric or a tubular knitted fabric knitted by double system knitting.

  Further, among the stitches knitted one course so as to include the empty needle knit, the stitches on the empty needles on the needle bed facing the stitches locked to the knitting needles on the knitting needle side adjacent to one of the knitting needles forming the additional stitches are formed. The transfer operation can be applied to increase the knitting width or to increase or decrease the stitches and knitting with a constant knitting width. For example, when the knitting width is increased, all the stitches locked to one knitting needle with respect to the knitting needles forming the additional stitches are transferred to the empty needles on the opposing needle bed. In addition, when knitting with a constant knitting width, it may be increased and decreased in the knitted fabric, and the stitches locked between the knitting needles forming the decreasing stitches (multiple stitches) from the knitting needles forming the increasing stitches. Transfer and form a double eye.

  The method for forming an additional stitch according to the present invention is suitable for knitting a knitted fabric on which an additional stitch is formed while performing a double system knitting with good productivity.
