Knitting method for knitted fabrics and device for distributing knitting data to the cam system of a flat knitting machine

Abstract

The present invention provides a knitting method for knitted fabrics and a device for allocating knitting data to a cam system of a flat knitting machine. Each piece of knitted fabric consisting of a plurality of tubular pieces is knitted in parallel on a needle bed of a flat knitting machine. For a row of a cam carriage in which the transfer of loops between needle beds is not performed, the knitting of the piece in front of the cam carriage in the direction of travel is allocated to the front cam system along the direction of travel, and the knitting of the piece in the rear of the cam carriage in the direction of travel is allocated to the rear cam system along the direction of travel. For a row of a cam carriage in which the transfer of loops between needle beds is performed, the knitting of all the pieces knitted in the row is allocated to one or more cam systems of the cam carriage. By shortening the stroke of the cam carriage, the knitting time of the knitted fabric is shortened.

Description

Technical Field

[0001] The invention relates to a method for knitting knitted fabrics on a flat knitting machine and a device for distributing knitting data. Background Art

[0002] For example, Patent Document 1 (Japanese Patent No. 4233409) discloses a knitting method in which a pullover consisting of left and right sleeves and a central front and back body is knitted as three tubes from the hem to the collar, and the sleeves are joined to the front and back body.

[0003] The flat knitting machine used for knitting has at least a pair of front and rear needle beds and a cam carriage running on the needle beds. The cam carriage operates the needles of the needle bed through a cam system, and the cam carriage has a plurality of cam systems dedicated to knitting and a cam system dedicated to stitch transfer, or a plurality of cam systems for both knitting and stitch transfer. Then, the knitting yarn is supplied to the needle from a yarn feeder running on a track above the cam carriage.

[0004] In Patent Document 1, one cam system and different yarn feeders are assigned to the right sleeve, front and back body pieces, and left sleeve. The knitting width of the left and right sleeves is increased in the middle of knitting, and the sleeves are joined to the front and back body pieces. Therefore, it is necessary to transfer the stitches, and a cam system different from that used for knitting is used for the transfer.

[0005] exist Figure 7 2 shows the stroke ST of the cam carriage in the above case. 2 is the pullover, 5 is the right sleeve, 6 is the left sleeve, 7, 8, 9 are the rib structure of the hem, 10a is the front neckline, and 10b is the front neckline. In addition, the sleeves 5 and 6 are joined to the front and back body pieces 4 at the armpit portion. The cam carriage 12 is provided with cam systems 14a, b, and c capable of knitting and transferring stitches, for example. In the conventional example, for example, the central cam system 14b is allocated to the front and back body pieces 4 and the left and right sleeves 5 and 6, so the stroke ST becomes longer.

[0008] [Patent Document 1] Japanese Patent No. 4233409 Summary of the invention

[0009] [Problems to be solved by the invention]

[0010] An object of the present invention is to shorten the knitting time by shortening the stroke of the carriage when knitting a knitted product such as a pullover.

[0011]

Methods for solving the problem

[0012] A method for knitting a knitted fabric of the present invention is characterized in that, on a flat knitting machine having at least a pair of front and rear needle beds and a cam system, wherein the cam system has a plurality of needles operating the needle beds along the length direction of the needle beds to form loops, each piece of a knitted fabric consisting of a plurality of tubular pieces is knitted in parallel on the needle beds, the knitting method comprising:

[0013] For the rows of the cam carriage that do not transfer stitches between needle beds, the knitting of the garment parts in the front direction of the cam carriage is assigned to the front cam system along the direction of travel, and the knitting of the garment parts in the rear direction of travel is assigned to the rear cam system along the direction of travel.

[0014] For a course of the carriage in which stitches are transferred between needle beds, knitting of all parts knitted in the course is allocated to one or more cam systems of the carriage.

[0015] The device for allocating knitting data to a cam system of a flat knitting machine of the present invention is configured to allocate knitting data to the cam system of the flat knitting machine in the following manner in order to knit each piece of a knitted fabric composed of a plurality of tubular pieces on the needle bed in parallel on a flat knitting machine having a cam system including at least a pair of front and rear needle beds and a cam carriage, wherein the cam carriage has a plurality of needles operating the needle beds along the length direction of the needle beds to form a stitch:

[0016] For the rows of the cam carriage that do not transfer stitches between needle beds, the knitting of the garment parts in the front direction of the cam carriage is assigned to the front cam system along the direction of travel, and the knitting of the garment parts in the rear direction of travel is assigned to the rear cam system along the direction of travel.

[0017] For a course of the carriage in which stitches are transferred between needle beds, knitting of all parts knitted in the course is allocated to one or more cam systems of the carriage.

[0018] In the present invention, the stroke of the cam carriage can be shortened, so the knitting time is shortened. In this specification, allocating knitting of a course without stitch transfer to a cam system means allocating knitting of a part to a cam system that operates needles of a needle bed to form stitches.

[0019] Preferably, the cam carriage has two cam systems along the length direction of the needle bed, the knitted fabric is composed of two sleeves and front and back body pieces, and for the row of cams where the stitches between the needle beds are not transferred, the sleeves in the front direction of the cam carriage are allocated to the front cam system along the travel direction and knitted, the front and back body pieces are allocated to any one of the two cam systems and knitted, and the sleeves in the rear direction of the travel direction are allocated to the rear cam system along the travel direction and knitted. In this way, by using a flat knitting machine having two cam systems along the length direction of the needle bed, it is possible to efficiently knit a knitted fabric composed of two sleeves and front and back body pieces.

[0020] In addition, it is preferred that the carriage has at least three cam systems along the length direction of the needle bed, the knitted fabric is composed of two sleeves and front and back body pieces, and for a row of the carriage in which the stitches between the needle beds are not transferred, the sleeves in the front direction of the carriage are allocated to the front cam system along the travel direction and knitted, the front and back body pieces are allocated to the center cam system along the travel direction and knitted, and the sleeves in the rear direction of the travel direction are allocated to the rear cam system along the travel direction and knitted. In this way, by using a flat knitting machine having three cam systems along the length direction of the needle bed, it is possible to knit a knitted fabric composed of two sleeves and front and back body pieces particularly efficiently.

[0021] In the modified example, the following courses are performed for the carriage course with the stitches between the needle beds:

[0022] The operation of returning the loops of the rear knitted fabric from the front needle bed to the rear needle bed and the operation of transferring the loops of the front knitted fabric are performed simultaneously by one cam system capable of transferring the loops, and then the loops of the front knitted fabric transferred to the rear needle bed are formed into loops by the cam system capable of knitting;

[0023] The operation of returning the loop of the front knitted fabric from the rear needle bed to the front needle bed and the operation of transferring the loop of the rear knitted fabric are simultaneously performed by one cam system capable of transferring the loop, and then the loop of the rear knitted fabric transferred to the front needle bed is formed into a loop by the cam system capable of knitting.

[0024] In the modified example, the operation of returning the stitch and the operation of transferring the stitch are performed by the same cam system, so the knitting efficiency is improved. The modified example is particularly suitable for rib knitting.

[0025] In a variant, it is preferred to use a 4-cam system capable of transferring and knitting.

[0026] In the row of the carriage with the transfer of the stitches between the needle beds,

[0027] Along the traveling direction of the cam carriage, the front cam system is allocated to the transfer loop, the second cam system is allocated to the knitting of the garment piece in the front direction of the traveling direction, the third cam system is allocated to the transfer loop, and the fourth cam system is allocated to the knitting of the garment piece in the rear direction of the traveling direction.

[0028] Alternatively, along the traveling direction of the cam carriage, the front cam system is assigned to the knitting of the garment piece in the front direction of the traveling direction, the second cam system is assigned to the transfer, and the third cam system is assigned to the knitting of the garment piece in the rear direction of the traveling direction, and the fourth cam system is assigned to the transfer.

[0029] In this case, in the knitting of the front knitted fabric and the knitting of the back knitted fabric, the cam system assigned to the transfer stitch and the cam system assigned to the knitting are opposite. In this way, the operation of returning the stitch and the operation of transferring the stitch can be performed by the same cam system, and the stroke of the cam carriage can be shortened.

[0030] In a modified example, it is preferred to use a three-cam system that can perform transfer and knitting.

[0031] In the row of the carriage with the transfer of the stitches between the needle beds,

[0032] When the cam carriage moves in the first direction, the front cam system is allocated to the knitting of the garment pieces in the front direction along the moving direction of the cam carriage, the second cam system is allocated to the transfer, and the third cam system is allocated to the knitting of the garment pieces in the rear direction.

[0033] Furthermore, when the cam carriage moves in the second direction, the front cam system is allocated to the transfer along the moving direction of the cam carriage, the second cam system is allocated to the knitting of multiple tubular knitted fabrics (knitting of all tubular knitted fabrics), and the third cam system is allocated to the transfer.

[0034] In this case, the cam system assigned to the transfer and the cam system assigned to the knitting are also opposite in the knitting of the front knitted fabric and the knitting of the rear knitted fabric. The first direction and the second direction are opposite directions, one direction is the knitting of the front knitted fabric, and the other direction is the knitting of the rear knitted fabric. In this case, the operation of returning the stitch and the operation of transferring the stitch can also be performed by the same cam system, and the stroke of the cam carriage can be shortened.

[0035] The target knitted fabric is a knitted fabric in which a plurality of tubular knitted fabrics are knitted in parallel, such as a pullover, trousers, and a sweater with an open collar. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] The best embodiment for carrying out the invention is shown below.

[0070] [Example]

[0071] Figure 1 The knitting method of the first embodiment is shown. In the figure, 2 is a knitted product, which is a pullover here, but it can also be a pair of left and right tubular knitted fabrics such as trousers. The knitted product 2 is a knitted product composed of a plurality of tubular garment parts. 4 is the front and back body parts, 5 is the right sleeve, and 6 is the left sleeve, all of which are tubular garment parts. The rib knitting structures 7, 8, and 9 at the hem are knitted, and the sleeves 5 and 6 are joined to the front and back body parts 4 at the armpit. 10a is the front neckline, 10b is the front neckline, and 11 is the shoulder.

[0072] The knitted fabric 2 is knitted on a flat knitting machine using a cam carriage 12 equipped with three cam systems 14a, b, and c. In addition, during knitting, the front and rear body pieces 4 and the sleeves 5 and 6 are knitted in parallel. The cam systems 14a, b, and c are cam systems that can perform knitting and stitch transfer. For knitting courses that do not require stitch transfer, the cam system 14a is assigned to the right sleeve 5, the cam system 14b is assigned to the front and rear body pieces 4, and the cam system 14c is assigned to the left sleeve 6. In this way, the front cam system is assigned in the same direction as the traveling direction of the cam carriage 12 to the front piece, the central cam system is assigned to the central piece, and the rear cam system is assigned to the rear piece.

[0073] Here, a knitting course is one movement of the cam carriage 12. In addition, knitting yarns are supplied to the sleeves 5 and 6 and the front and rear body pieces 4 from different yarn feeders. In addition, the cam carriage 12 is equipped with cam systems 14a, b, and c on the front needle bed and the rear needle bed. The cam system on the front needle bed knits the front knitted fabric of the tubular knitted fabric by operating the needles of the front needle bed, and the cam system on the rear needle bed knits the rear knitted fabric of the tubular knitted fabric by operating the needles of the rear needle bed. The cam system on the front needle bed and the cam system on the rear needle bed are arranged symmetrically in the longitudinal direction of the needle beds. The following shows the allocation of the cam system on the front needle bed side, and the cam system on the rear needle bed side is also allocated to the garment parts of the knitted fabric in the same way.

[0074] When knitting into a tubular shape, the stitches need to be transferred when knitting the rib knitted structures 7, 8, and 9. In addition, transfer is also required when increasing the knitting width of the sleeves 5 and 6 during knitting, joining the sleeves 5 and 6 to the front and back body pieces 4, etc. In a knitting course with transfer, different cam systems are required for knitting and transfer, so for example, the central cam system 14b is allocated to knitting, and the cam systems 14a and c on both sides are allocated to transfer.

[0075] exist Figure 1 In the embodiment of the present invention, for the knitting rows without transfer (rows consisting of the front stitches formed by knitting, the front stitches formed by tucking, and the floating stitches), the stroke ST of the cam carriage 12 is shortened. One end of the stroke ST is determined by the condition that the unillustrated needle selection device between the cam system 14a and the cam system 14b can select needles for knitting the right sleeve 5, and the other end is determined by the condition that the unillustrated needle selection device between the cam system 14c and the cam system 14b can select needles for knitting the left sleeve 6. As a result, the stroke ST of the cam carriage 12 is shorter than Figure 7 The situation is shorter, and the knitting time is reduced by, for example, several%.

[0076] Figure 2The second embodiment of the present invention uses a cam carriage 16 having two cam systems 14a and 14b for both knitting and transfer. Alternatively, a cam carriage having two cam systems for knitting and two cam systems for transfer may be used. In the second embodiment, for example, the cam system 14a is allocated to the right sleeve 5 and the front and back pieces 4, and the cam system 14b is allocated to the left sleeve 6. The stroke ST of the cam carriage 16 is shown in the figure. Figure 7 Of course, the gusset system 14a can also be distributed to the right sleeve 5, and the gusset system 14b can be distributed to the front and back body pieces 4 and the left sleeve 6.

[0077] Figure 3 The distribution algorithm for the triangular system of the first and second embodiments is shown. Figure 3 The processing is performed by a design system that converts the design data of the knitted fabric 2 into knitting data, or by a controller of a flat knitting machine. Alternatively, it can be performed by a computer that is independent of both the design system and the flat knitting machine.

[0078] Assume that knitting data for knitting the knitted fabric 2 is given in advance, and the knitting data is read from an appropriate memory in step S1. In the knitting data, for each knitting course, it is specified which yarn feeder is to be moved with what stroke, and which needle of the needle bed 21 is to be operated by the cam carriage 12, 16. However, which cam system 14a, b, c is used for knitting can be changed.

[0079] In the case of a stitch transfer operation including stitches in a knitting row, for example, the knitting (stitch formation) of all garment parts including the right sleeve 5, the front and rear body pieces 4, and the left sleeve 6 is assigned to one cam system (steps S2 and S3). However, it can also be assigned to multiple cam systems. In addition, stitch transfer and knitting are performed in other cam systems.

[0080] In the case of a loop transfer operation that does not include loops in a knitting row, the garment pieces in front of the traveling direction of the triangle carriage are assigned to the front triangle system along the same direction, and the garment pieces behind the traveling direction of the triangle carriage are assigned to the rear triangle system along the same direction (step S4).

[0081] For example, Figure 1In the case of , when the cam carriage 12 is moving from left to right in the figure, the left sleeve 6 is assigned to the cam system 14c, the front and rear body pieces 4 are assigned to the central cam system 14b, and the right sleeve 5 is assigned to the rear cam system 14a. When the cam carriage 12 is moving in the reverse direction, the assignment of the garment parts 4, 5, 6 to the cam systems 14a, b, c is not changed, which is the most efficient. That is, when the three cam systems 14a, b, c are assigned to the three garment parts 4, 5, 6, the left cam system 14a is assigned to the left garment part 5 on the needle bed, the central cam system 14b is assigned to the central garment part 4, and the right cam system 14c is assigned to the right garment part 6, which is the most efficient.

[0082] In addition, although the efficiency is reduced, the left sleeve 6 can be allocated to the cam system 14c, and the front and rear body pieces 4 and the right sleeve 5 can be allocated to the cam system 14a. Similarly, although the knitting efficiency is reduced, the left sleeve 6 and the front and rear body pieces 4 can be allocated to the cam system 14c, and the right sleeve 5 can be allocated to the cam system 14a.

[0083] exist Figure 2 In the case of, when the direction of travel of the cam carriage 16 is from left to right in the figure, the left sleeve 6 is allocated to the cam system 14b, and the front and rear body pieces 4 and the right sleeve 5 are allocated to the rear cam system 14a. When the direction of travel of the cam carriage 12 is reversed, the allocation of the garment parts 4, 5, 6 to the cam systems 14a and b is not changed. In addition, even if the left sleeve 6 and the front and rear body pieces 4 are allocated to the cam system 14b, and the right sleeve 5 is allocated to the cam system 14a, the knitting efficiency is the same, and the allocation concept of the cam systems 14a and b is the same. In summary, on the needle bed, the left cam system 14a is allocated to the left garment part 5, the right cam system 14b is allocated to the right garment part 6, and either the left or right cam system is allocated to the central garment part 4.

[0084] In addition, when knitting a knitted product consisting of a pair of left and right tubular knitted fabrics, Figure 1 In the case of Figure 2 In the case of the above, the front tubular fabric is distributed along the same direction to the front cam system in the traveling direction of the cam carriage 12, and the rear tubular fabric is distributed along the same direction to the rear cam system.

[0085] The processes of steps S2 to S4 are carried out for all knitting courses, and when the allocation of the cam system is completed, the allocation result for each knitting course is output (steps S5 and S6).

[0086] Figure 4The figure shows a flat knitting machine 20 equipped with a distribution device 32 for distributing a cam system to parts of a knitted product. The distribution device 32 may be provided in a knitted product design system or may be an independent device.

[0087] The flat knitting machine 20 includes, for example, a front needle bed 21 and a rear needle bed (not shown), or may include other needle beds. The cam carriage 22 reciprocates on the needle bed 21 and the like via a driver 23, and includes, for example, two cam systems 24 for knitting and two cam systems 25 for transferring.

[0088] The cam carriage 22 is provided with cam systems symmetrically on the front needle bed 21 side and the rear needle bed side (not shown), and the front knitted fabric is knitted by the cam systems 24 and 25 on the front needle bed side, and the rear knitted fabric is knitted by the cam system (not shown) on the rear needle bed side. In addition, on the front needle bed side and the rear needle bed side, the cam systems at the same position along the longitudinal direction of the needle bed are allocated to the same garment parts.

[0089] A plurality of rails 26 are arranged parallel to the needle bed 21 above the needle bed 21, and a yarn feeder (not shown) travels to supply knitting yarn to the needles of the needle bed 21. In addition, the yarn feeder is supplied with knitting yarn from a yarn package (not shown) mounted on the top plate 27 via an antenna device (not shown).

[0090] The distribution device 32 includes a CPU 34 and memories 35 and 36, and stores the knitting data before the distribution of the cam systems 24 and 24 in the memory 35. For the knitting rows without transfer, the knitting rows are divided according to the knitting data. Figure 3 The algorithm allocates either the left or right triangle system 24, 24, and stores the allocation result in the memory 36. Figure 4 In the case of, the data of the memory 36 is output to a controller (not shown) in the flat knitting machine 20. In the case of providing the allocating device 32 in the design system, the data of the memory 36 is used in the design system to output the knitting data of the cam system that has been allocated.

[0091] Figure 4 The tripod slide 22 and Figure 2 as well as Figure 5 The cam carriage 16 is equivalent to the cam system 14a, b used for both transfer and knitting, which is equivalent to alternately having two cam systems 24 dedicated to knitting and two cam systems 25 dedicated to transfer.

[0092] Alternatively, the tripod carriage 22 may be replaced by Figure 1 as well as Figure 6 The cam system 12. The cam carriage 12 has a total of three cam systems 14a, b, and c for both transfer and knitting.

[0093] In the embodiment, the reciprocating stroke ST of the cam carriages 12, 16, 22 is shortened to improve the knitting efficiency of knitted fabrics.

[0094] Modifications

[0095] Figure 8 A modification example related to the transfer of coils is shown. When knitting a knitted fabric that requires transfer of coils, such as a tubular ribbed fabric, it is necessary to perform rib knitting on the front knitted fabric after transferring the coils of the front knitted fabric to the rear needle bed, and then move the coils of the front knitted fabric after the transfer back to the front needle bed. In addition, it is necessary to perform rib knitting on the rear knitted fabric after transferring the coils of the rear knitted fabric to the front needle bed, and then move the coils of the rear knitted fabric after the transfer back to the rear needle bed. In the past, the transfer and return of coils were performed separately. Therefore, in the above-mentioned knitting, it is necessary to make the cam system perform a total of 4 actions for the transfer of coils, and a total of 2 actions for the knitting. If the same cam system is used to transfer and return the coils at the same time, the knitting efficiency is improved.

[0096] Figure 8 1) indicates the state before the start of ribbing knitting in draw-needle knitting. Figure 8 In the middle, ○ indicates the front stitch of the front knitted fabric, ● indicates the back stitch of the front knitted fabric, △ indicates the front stitch of the back knitted fabric, ▲ indicates the back stitch of the back knitted fabric, the upper needle bed is the back needle bed, the lower needle bed is the front needle bed, and the solid line between the stitches is the knitting yarn. Knitting can be implemented on a flat knitting machine with two needle beds, front and back, or on a flat knitting machine with a total of four needle beds, front, back, top and bottom.

[0097] In 2), the stitches are transferred to prepare for rib knitting, and in 3), one course of rib knitting is performed on the front knitted fabric. 1) to 3) can be appropriately changed in the preparation of the modified example.

[0098] In 4), the back loops of the front knitted fabric and the back loops of the back knitted fabric are transferred to the front needle bed using one cam system. That is, the back loops of the front knitted fabric after ribbing and the back loops of the back knitted fabric are transferred using the same cam system at the same time. Then, in 5), the back knitted fabric is ribbed for one row.

[0099] In 6), the back loops of the rear knitted fabric and the back loops of the front knitted fabric are transferred to the rear needle bed using one cam system. That is, the back loops of the rear knitted fabric after ribbing and the back loops of the front knitted fabric are transferred using the same cam system. Next, in 7) (same as 3), one row of rib knitting is performed on the front knitted fabric. Then, 3) to 6) are repeated. In 4) and 6), the back loops after ribbing and the back loops before ribbing are transferred using the same cam system, so the knitting efficiency is improved.

[0100] Fig. 9 Indicates that Figure 8 An example of a knitting method applied to an embodiment. The rib knitting structures 7, 8, and 9 of the front and back body pieces 4, the right sleeve 5, and the left sleeve 6 are knitted using a cam carriage having four cam systems 144a to d capable of knitting and transferring. The "front" on the central arrow indicates the rib knitting course of the front knitted fabric, and the "back" indicates the rib knitting course of the back knitted fabric.

[0101] In the knitting of the front knitted fabric, the first cam system 144a and the third cam system 144c are allocated to the transfer (the transfer of the loops of the rear knitted fabric and the transfer of the loops of the front knitted fabric), and the second cam system 144b and the fourth cam system 144d are allocated to the knitting. Then, the second cam system 144b is allocated to the knitting of the right sleeve 5 and the front and rear body pieces 4, and the fourth cam system 144d is allocated to the knitting of the left sleeve 6.

[0102] In the knitting of the back knitted fabric, the first cam system 144d and the third cam system 144b are allocated to the transfer of the stitches of the front knitted fabric and the transfer of the stitches of the back knitted fabric, and the second cam system 144c and the fourth cam system 144a are allocated to the knitting. Then, the second cam system 144c is allocated to the knitting of the left sleeve 6, and the fourth cam system 144a is allocated to the knitting of the right sleeve 5 and the front and back body pieces 4.

[0103] exist Fig. 9 In the case of , the stroke required by the cam system 144b becomes the stroke ST1, and the stroke required by the cam system 144d becomes the stroke ST2, and the stroke of the cam carriage is shortened as a whole. In addition, since one cam system is used to transfer and return the stitches at the same time, the cam system required for transferring stitches between the cam systems used for knitting can be one. That is, two of the four cam systems can be used for knitting.

[0104] In addition, the knitting of the front and rear body pieces 4 may be allocated to the cam systems 144d and 144c. In addition, the front and third cam systems in the traveling direction may be allocated to knitting, and the second and last cam systems may be allocated to transfer. Specifically, the front and second cam systems in the traveling direction may be allocated to knitting and transfer of the garment pieces in the front direction of the traveling direction, and the third and fourth cam systems in the traveling direction may be allocated to knitting and transfer of the garment pieces in the rear direction of the traveling direction. In either case, the allocation of the cam systems is reversed between knitting and transfer in the knitting of the front knitted fabric and the knitting of the rear knitted fabric.

[0105] exist Fig.10 In the process, a 3-cam system capable of knitting and transferring stitches is used to knit the rib knitting structures 7 to 9 of the front and back body pieces 4 and the left and right sleeves 5 and 6. The meaning of the symbols is the same as Fig. 9The same. In the knitting of the front knitted fabric, the foremost cam system 144a is allocated to the knitting of the right sleeve 5 and the front and rear body pieces 4. The second cam system 144b is allocated to the transfer (the transfer of the stitches of the front knitted fabric and the transfer of the stitches of the rear knitted fabric relative to the right sleeve and the front and rear body pieces, and the transfer of the stitches of the front knitted fabric and the transfer of the stitches of the rear knitted fabric relative to the left sleeve). The third cam system 144c is allocated to the knitting of the left sleeve 6.

[0106] In the knitting of the back knitted fabric, the front cam system 144c is allocated to the return of the stitches of the front knitted fabric and the transfer of the stitches of the back knitted fabric, and the second cam system 144b is allocated to the knitting of the left and right sleeves 5, 6 and the front and back body pieces 4. The third cam system 144a is allocated to the return of the stitches of the back knitted fabric and the transfer of the stitches of the front knitted fabric.

[0107] In the knitting of the front knitted fabric, the stroke required by the cam system 144a becomes the stroke ST1, and the stroke required by the cam system 144c becomes the stroke ST2. Fig. 9 The strokes ST1 and ST2 are substantially the same. In both the front and rear knitted fabrics, the stroke required by the cam system 144b is the stroke ST3. As a whole, the cam carriage connected with the cam systems 144a to c has a shorter stroke in both the knitting of the front and rear knitted fabrics. In addition, since the same cam system is used for the return and transfer of the loops, efficient knitting is possible.

[0108] In addition, in the knitting of the front knitted fabric, the knitting of the front and rear body pieces 4 may be allocated to the cam system 144c. In addition, in the knitting of the front knitted fabric, the two cam systems 144a and 144c may be allocated to the transfer and the cam system 144b may be allocated to the knitting, and in the knitting of the back knitted fabric, the two cam systems 144a and 144c may be allocated to the knitting and the cam system 144b may be allocated to the transfer. In either case, the allocation of the cam systems is reversed between knitting and transfer in the knitting of the front knitted fabric and the knitting of the back knitted fabric.

[0109] In the embodiment, the rib knitting of the hem is shown as the knitting course with transfer, but the rib knitting of the part other than the hem is also the same. The same is also true when knitting a knitted fabric in which the front stitch and the back stitch are mixed, such as a double purl structure.
