Abstract

To capture a knitting yarn which is floating from a tip part and difficult to capture surely in the hook of a knitting needle. When a stitch loop (8) is transferred to the knitting needle (4) of a rear needle bed (2) in order to increase the stitch loop (8) formed by the knitting needle (3) of a front needle bed (1), the knitting yarn (7) is also fed to the hook (3a) of the knitting needle (3) from a yarn carrier (6) to form a new stitch loop. When the knitting needle (3) is pulled in to the front needle bed (1) side, the stitch loop (8) remaining in the knitting needle (3) raises a latch (3b) and displaces it to close the hook (3a). Sincethe knitting yarn (7) hanging down from the distal end of the feeder of the yarn carrier (6) extends in the direction perpendicular to the paper surface and passes through the open/close range of the latch (3b), the knitting yarn (7) can be captured in the hook (3a).

Knitting method of knitted fabric and design device

Technical field

[0001] The present invention relates to a knitted fabric for catching a knitting yarn hooked on a knitting needle by an intarsia pattern, floating knitting, etc., so that the knitting yarn is fed so as not to be hooked on the knitting needle and fed as a transition yarn. The present invention relates to a knitting method and a design apparatus.

Background art

Conventionally, in a flat knitting machine, a plurality of knitting yarns are switched on the same knitting course to knit a knitted fabric including an intarsia pattern (see, for example, Patent Document 1) o

The knitting yarn used for knitting the knitted fabric in the flat knitting machine is supplied to the knitting needle from a yarn supplying member such as a yarn carrier that moves along the mouth so as to be interlocked with the knitting operation of the knitting needle. The intarsia pattern to be knitted has a shape that fits into the ground knitted fabric. For this reason, yarn insertion and yarn extraction using knitting yarns different from the knitted fabric of the ground are performed at the start and end of the intarsia pattern.

[0003] When the knitting yarn to be inserted into the yarn becomes a transition yarn that is skipped without being hooked on the knitting needle, the yarn feeding position from the yarn carrier or the like is increased at the end of the knitting of the intarsia pattern or the like. Floating from the tooth opening makes it difficult to catch the knitting needle on the hook. Also, in the transition section that has become a transition yarn after the yarn has been unwound, there is a risk that the knitting needle that is knitting the knitted fabric may be accidentally hooked into the knitting needle and knitted into the knitted fabric, which may become an obstacle to the knitting operation. There is also. The problem that the crossover yarn floats from the mouth and becomes difficult to catch on the knitting needle occurs not only in the knitting of the Intarsia pattern, but also in the knitted fabric of the floating knitting. In order to prevent the crossover yarn from floating from the mouth in the crossover section and to make sure that the knitting needle catches the crossover yarn as the knitting yarn at the end of the knitting section, it is necessary to tack the knitted fabric in the crossover section with tack or the like. Processing such as knitting is performed to prevent the transfer yarn from floating from the mouth. However, if the crossover yarn is knitted into the knitted fabric, it will be necessary to remove the knitted crossover yarn in the subsequent process. [0004] There has also been proposed a yarn processing method and a knitting method in which a knitting yarn that becomes a transition yarn is temporarily captured using a knitting needle in a transition section, and the transition yarn captured after knitting of a plurality of courses is released. (For example, see Patent Documents 2 and 3.) However, if the interval between the knitting needles to be captured becomes long, the transition yarn floats from the mouth, so if the transition section becomes long, the number of knitting needles to be captured must be increased. A method is also disclosed in which the trapping of the transition yarn is guided and pressed below the hook without being hooked on the hook of the knitting needle (see, for example, Patent Document 4). This method is based on the premise that the operation of the knitting needle and the yarn supplying member can be individually controlled, and the yarn carrier is taken along with the yarn carrier while moving the carriage carrying the cam mechanism along the knitted fabric. A flat cam knitting machine must be equipped with a new cam mechanism.

Problems to be solved by the invention

[0005] An object of the present invention is to provide a knitting method and a design device for a knitted fabric that can surely capture a knitting yarn that floats from the mouth and becomes difficult to capture in the hook of the knitting needle.

Means for solving the problem

The present invention provides a flat knitting machine with a flat knitting machine in which at least a pair of front and back needle beds are provided so as to face each other at the mouth, and a number of flat needles are arranged as knitting needles on each needle bed. In the method of

A stitch that is held by the knitting needle of one needle bed that is used as a crossover yarn that is blown so that it does not catch on the knitting needle over a distance that is difficult to catch in the hook. The knitted fabric is characterized in that while the loop is increased to the knitting needle of the other needle bed, it is captured in the hook of the knitting needle of the one needle bed as a stitch loop newly formed by the knitting needle of the one needle bed. It is an organization method. [0007] Further, in the present invention, the knitting loop of the one needle bed is transferred to the knitting loop belonging to the other needle bed before the split increase, After the increase, the newly formed stitch loop is paid from the knitting needle of the one needle bed.

[0008] Further, in the present invention, the knitting yarn is used for knitting the inner region of the knitted fabric, and becomes a transfer yarn when the yarn is taken out of the knitted fabric,

The split increase is performed near the edge of the knitted fabric,

After the increase, the predetermined number of courses are knitted, and then the newly formed stitch loop is paid from the knitting needles of the one needle bed.

[0009] Further, in the present invention, following the above-described split increase, a stitch is formed on a knitting needle different from the knitting needle used for the split increase, and then newly formed by splitting the knitting needle on the one needle bed. It is characterized by paying a stitch loop.

[0010] Further, in the present invention, the stitch loop added to the knitting needle of the other needle bed or the stitch loop knitted following the stitch loop is transferred to the one needle bed side to be released. It is characterized by stopping.

[001 1] Further, in the present invention, the knitting yarn is threaded in a state of being a transition yarn from a portion knitted before a plurality of courses of the knitted fabric,

In the knitting course that performs the above-mentioned split increase, a portion where the knitting yarn intersects between the needle beds is formed near the end of the knitted fabric,

It is characterized in that the crossing portion is canceled after the passing yarn is threaded into and caught by the knitting needle that performs the split increase via the intersecting knitting yarn portion.

[0012] Furthermore, the present invention provides a knitted fabric with a flat knitting machine in which at least a pair of front and back needle beds are provided so as to face each other at the mouth, and each needle bed is provided with a number of flat needles as knitting needles. In a design device for a knitted fabric that generates knitting data for knitting, the knitting needle that performs the knitting operation alone is skipped over the distance that is difficult to catch in the hook, and is passed over to the knitting needle. For the knitting yarn

While the stitch loop held by the knitting needle of one needle bed is increased to the knitting needle of the other needle bed, the one needle is formed as a stitch loop newly formed by the knitting needle of the one needle bed. Capture in the hook of the floor knitting needle,

The knitting fabric design apparatus is characterized in that it generates knitting data for execution by a flat knitting machine.

The invention's effect

[0013] According to the present invention, a large number of spiral needles are arranged as a knitting needle on the pair of front and back needle beds, and the stitch loop is increased by increasing the split between the needle beds to the knitting needles of the opposing needle beds. Therefore, when the blade is closed in the mouth, the knitting yarn in the state of the transition yarn floating from the mouth is also guided into the hook, so that it can be surely captured and a stable knitted fabric can be knitted.

[0014] Further, according to the present invention, the stitch loop to be increased is transferred from the needle bed to which the knitted fabric belongs to the opposite needle bed, and the transferred stitch loop is The stitch loop can be returned to the original needle bed side. Since the new stitch loop is paid from the transferred knitting needle after the premium is added, processing of the newly formed stitch loop can be made unnecessary in the subsequent process.

[0015] Further, according to the present invention, even when the distance of the crossover yarn becomes long when the yarn is taken out, it is securely caught by the hook of the knitting needle near the end portion of the knitted fabric, and the predetermined course knitting is performed. The crossover thread can be kept from floating from the mouth

[0016] Further, according to the present invention, a stitch loop following the increased stitch loop is formed on a knitting needle different from the stitch loop used for the premium, and then the stitch loop is newly formed by increasing the stitch. Therefore, the stitches that are formed by a single knit knitting are returned to the knitted fabric before the transfer and the stitch loop is surely captured by using the additional warp. Can be equivalent to a loop.

[0017] Further, according to the present invention, it is possible to transfer the stitches back to the extra side without paying the extra stitch loop, and use them effectively to prevent the unraveling.

[0018] Further, according to the present invention, the state in which the knitting yarn that is inserted in the state of the transition yarn that does not hang on the knitting needle floats from the mouth is different in the position of the portion that has been used in the preceding knitting course. Depending on. Knitting yarn between needle beds before knitting course to use crossover yarn again Since the crossing part is formed, the passing yarn is fed to the knitting needle that performs the split increase through the crossing part. By forming the intersecting portion in the vicinity of the end of the knitted fabric, the condition for capturing the knitting yarn by the hook of the knitting needle can be surely captured by using the intersecting portion as the starting point of yarn insertion.

[0019] Further, according to the present invention, when the knitting yarn that is not applied to the knitting needle floats from the mouth and becomes a crossover yarn, the knitting data is obtained so that the hook of the knitting needle is reliably captured by increasing the knitting needle. Can be created.

[0022] Fig. 1 shows a state in which a knitting yarn is captured in a hook of a knitting needle by utilizing a knitting operation of increasing knitting in one embodiment of the present invention. In a flat knitting machine having a front needle bed 1 and a rear needle bed 2, for example, in order to carry out a knitting method as disclosed in Japanese Patent Publication No. 6 2-5 2 0 6 3, a preceding course A mechanism for driving the knitting needles 3 and 4 that can form a new stitch loop with the knitting needle on the stitch transfer side is prepared while transferring the stitch loop formed in step 1 between the needle beds. The front needle bed 1 and the rear needle bed 2 are opposed to each other with the tooth opening 5 interposed therebetween, and the leading ends of the knitting needles 3 and 4 can be advanced and retracted relative to the tooth opening 5. On the tip side of the knitting needles 3 and 4, hooks 3a and 4a and latches 3b and 4b are provided, respectively. A blade 3 c is provided in the middle of the knitting needle 3 in order to transfer the stitch loop from one of the knitting needles 3 and 4 to the other at the mouth 5. Above the mouth 5, a yarn carrier 6 is provided so as to be movable in a direction perpendicular to the paper surface, and the knitting yarn 7 is supplied from the yarn feeder at the lower end. When the knitting yarn 7 is supplied to the hooks 3a and 4a of the knitting needles 3 and 4 at the tooth opening 5, the stitch loop 8 is formed by the knitting operation of the knitting needles 3 and 4, and the knitting needles 3 and 4 as the knitting progresses. The stitch loop 8 coming off from the stitch forms a knitted fabric 9 and hangs down below the mouth 5 due to its own weight and various urging forces. When the stitch loop 8 formed by the knitting needle 3 on the front needle floor 1 is increased, when the stitch loop 8 is transferred to the knitting needle 4 on the rear needle floor 2, the knitting yarn from the yarn carrier 6 is also applied to the hook 3 a of the knitting needle 3. 7 is fed to form a new stitch loop.

[0023] Fig. 1 (a) shows a state in which the stitch loop 8 is held in the blade 3c portion of the knitting needle 3 of the front needle bed 1 and advanced into the mouth 5 and then the rear needle bed 2 is placed in the blade 3c portion. The state after the hook 4a of the knitting needle 4 of Fig. 1 is entered and the stitch loop 8 is hooked on the hook 4a is shown. When the knitting needle 3 is pulled to the front needle bed 1 side, the stitch loop 8 is hooked to the hook 4 a of the knitting needle 4 of the rear needle bed 2.As a result, the needle loop 3 comes off the blade 3 c and opens to the tip of the blade 3 b. Get closer. As shown in FIG. 1 (b), when the knitting needle 3 is further pulled to the front needle bed 1 side, the stitch loop 8 remaining on the knitting needle 3 raises the latch 3 b and is displaced so as to close the hook 3 a. The position of the yarn carrier 6 is shifted from the knitting needles 3 and 4 in the direction perpendicular to the paper surface, but the knitting yarn 7 hanging from the tip of the yarn feeder is on the paper surface. It extends in the vertical direction and passes through the open / close range of the blade 3b. As shown in FIG. 1 (c), when the blade 3 b closes the hook 3 a while passing through the stitch loop 8, the knitting yarn 7 supplied from the yarn feeder of the yarn carrier 6 is moved into the hook 3 a. Can be captured. When the knitting needle 3 is further pulled into the front needle bed 1, the portion of the stitch loop 8 that is hooked to the knitting needle 3 rotates around the tip of the knitting needle 3 along the outer periphery of the lever 3b that closes the hook 3a, Detach from knitting needle 3. The detached stitch loop 8 is hooked only on the hook 4 a at the tip of the knitting needle 4 and becomes a stitch loop on the rear needle bed 2 side.At the same time, the stitch loop newly formed with the knitting needle 3 is The old loop is knocked over.

FIG. 2 shows an example of a cam system 10 for performing a knitting operation on the knitting needle 3 of the front needle bed 1 that becomes the transfer side in the split operation shown in FIG. As will be described later, this cam system shows one of a plurality of sets mounted on the carriage along the tooth opening 5 with the mouth side facing up. In the following, when the upper and lower sides are shown with reference to the mouth, similarly, it may be stated that the side closer to the mouth is up and the side away from the mouth is down.

[0025] The carriage base plate 11 facing the needle bed includes a stitch forming cam lock 15 including a needle raising cam 12 and stitch cams 13 and 14, a stitch receiving transfer cam 16 and a transfer receiver. A stitch transfer cam lock 18 including a dual transfer cam 17 is provided. The stitch cams 13 and 14 can be displaced along the direction parallel to the inclined cam surfaces 1 3 a and 14 a to adjust the stitches. The needle raising cam 12 has a lower fixed portion 19 and an upper movable portion 20. The movable part 20 is a mechanism that is not shown in the figure, alternately with the transfer-use transfer cam 17, and with respect to the ground plane 11, so that if one is in the protruding state, the other is in the sinking state. To do. The movable part 20 is provided with a bat draft inner groove 20a. The bag guide groove 20 a is bent in a mountain shape with the central part approaching the mouth side, and is connected to the slope of the fixed part 19 through the horizontal shoulder parts 20 b on both sides.

[0026] In the center of the upper portion of the fixed portion 1 9 is a stitch cam transfer cam 1 6 Provided. The stitch receiving transfer cam 16 is symmetrical, and is inclined at both ends so that the portion near the center is deep.

[0027] The transfer cam for both ends 1 7 of the needle raising cam 1 2 is generally a mountain-shaped triangle in which two apexes are arranged, and guides the back of the knitting needle on the stitch transfer side on the upper edge side, Guide the knitting needle bag on the stitch receiving side on the lower edge side. A transfer guide cam 21 is provided above the transfer-use transfer cam 17 and a needle guide cam 22 is provided on both sides thereof.

[0028] When driving the knitting needle 3 on the stitch transfer side, move the movable part 20 of the needle raising cam 12 as shown in a two-dot chain line, as shown by the two-dot chain line, and as shown in FIG. Leave it out. The knitting needles 3 and 4 are provided with two bats that receive driving for knitting operation by the cam system 10, and the upper bat 2 3 receives the action of the stitch transfer cam lock 18, and the lower bat 2 4 receives the action of stitch forming cam lock 1 5. Assuming that the carriage equipped with the cam system 10 travels to the left in the figure, the upper bat 2 3 and the lower bat 24 on the transfer side knitting needle 3 are routed as shown by the two-dot chain line. Move. Note that the positions of the upper bat 2 3 and the lower bat 24 corresponding to (a), (b), (c) in FIG. 1 are 2 3 a, 2 3 b, 2 3 c; 2 4 a, 2 4 b , 2 4 c respectively. Further, the position indicated as the yarn carrier 6 indicates a position where the yarn supply of the yarn carrier 6 receives the knitting yarn supplied to the hook 3 a of the knitting needle 3.

[0029] FIG. 3 shows a state in which the knitting operation as the stitch receiving side is performed on the knitting needle 4 of the rear needle bed 2 using the cam system 10 of FIG. The In FIG. 3, the cam system 10 of FIG. 1 is mounted on the carriage of the front needle bed 1 while it is mounted on the carriage of the rear needle bed 2. It is shown to be symmetric with Figure 2. In FIG. 3, parts corresponding to those in FIG. 2 are given the same reference numerals, and duplicate descriptions are omitted. However, when the knitting needle 4 on the stitch receiving side is driven, the movable part 20 of the needle raising cam 12 is in the sunk state as shown by the two-dot chain line, and the transfer-use transfer cam 17 is in the extended state as shown by the solid line Keep it as [0030] Although not shown in FIG. 2, the knitting needle 4 is also subjected to the action of the pressers 25, 26, and 27. The cam system 10 is a position where the knitting needle 4 is subjected to the action of the pressers 25, 26, and 27, among the 3 positions, as disclosed in Fig. 1 in Japanese Patent Publication No. 2-10262. The needle is selected. The knitting needles 3 and 4 are basically the same as those disclosed in FIG. 2 of the Japanese Examined Patent Publication No. 2_010262.

[0031] The pressers 25, 26, and 27 can individually switch between action and non-action. When the knitting needle 4 is operated as the stitch receiving side, the intermediate presser 27 is kept inactive as indicated by a two-dot chain line. When the pressers 25 and 26 are applied to the knitting needle 4, the lower butt 24 of the knitting needle 4 is not affected by the fixing portion 1 9 of the needle raising cam 1 2, and is acted by the transfer cam 1 7 at the center. It rises to the mouth side. When the knitting needle 4 is raised, the upper butt 23 is transferred and comes into contact with the lower edge of the dual-purpose transfer cam 17 and descends along the guide surface formed at the lower edge. When the lower battery 24 comes into contact with the sloped force surface 1 3 a of the stitch cam 13, it is guided so as to descend along the cam surface 13 a. The positions of the upper bat 23 and the lower bat 24 corresponding to (a), (b), and (c) in Fig. 1 are indicated by 23 a, 23 b, 23 c and 24 a, 24 b, 24 c, respectively. .

FIG. 4 shows a state in which the knitting needle 3 performs the knitting operation of the knee using the cam system 10 of FIG. At the knitting, the tip of the knitting needle 3 is once advanced into the tooth opening 5 until it reaches a clear position where the stitch loop 8 retracts from the bevel 3 b. The stitch loop 8 connected to the knitted fabric 9 remains near the tip of the front needle bed 1 because the knitted fabric 9 is biased below the tooth opening 5. Fig. 4 (a) shows a state in which the knitting needle 3 that has advanced into the tooth opening 5 to the clear position is pulled back to the front needle bed 1 and one yarn is supplied from the yarn carrier 6. As shown in FIG. 4 (b), when the knitting needle 3 is drawn into the front needle bed 1 and retracted from the tooth opening 5, the stitch loop 8 begins to close the spatula 3b. As shown in Fig. 4 (c), the blade 3 b closes the hook 3 a, and the knitting yarn 7 hangs down from the yarn feeder at the lower end of the yarn carrier 6 until the stitch loop 8 is released from the tip of the knitting needle 3. If the position is high, the knitting yarn 7 cannot be caught in the hook 3a and entrapped. As described in Patent Document 4 with reference to FIG. 2, the height of the knitting yarn 7 is high after a long unknitted section, and it is difficult to cause the yarn to bite in the knitting operation of the knit. Become.

FIG. 5 shows a switching state of the cam system 10 when the knit knitting operation as shown in FIG. 4 is performed. When the knitting needle 3 is driven by the knitting operation of the knit, the movable part 20 of the needle raising cam 1 2 is in the extended state as indicated by the solid line, and the transfer transfer cam 17 for the transfer is in the retracted state as indicated by the two-dot chain line Keep it as Even if the knitting needle 3 performs the knitting operation for transferring stitches in the state of FIG. 2, if the opposing knitting needle 4 does not perform the knitting operation for receiving the stitch in the state of FIG. 3, the knitting needle 3 is knit. A similar stitch loop is formed. Note that the positions of the upper bat 2 3 and the lower bat 24 corresponding to (a), (b), (c) in FIG. 4 are 2 3 a, 2 3 b, 2 3 c; 2 4 a, 2 4 b , 2 4 c respectively. The position indicated as yarn carrier 6 indicates the position at which the yarn 3 is supplied to the hook 3 a of the knitting needle 3 from the yarn feeder of the yarn carrier 6.

FIG. 6 shows a simplified example of the knitted fabric 9. In the X section in the wale direction, the pattern area 9 Xa of A is knitted, and in the Y section in the direction of wale, the pattern area 9 yb of B is knitted in each course in the pattern area 9 ya of A. To do. In the Z section in the wale direction, only the pattern area 9 z a of A is knitted. In such a knitted fabric 9, it is necessary to process the transition yarn when inserting the yarn at the end portion 28 of the pattern region 9 y b and when removing the yarn from the end portion 29.

FIG. 7 shows a schematic configuration of the flat knitting machine 30 for knitting the knitted fabric 9. The front needle bed 1 is provided with a carriage 31 equipped with a cam system that can be knitted, transferred, and increased. The carriage 31 reciprocally travels in the longitudinal direction of the needle bed by selectively entraining yarn carriers 6 a and 6 b that can travel along the yarn path rail 3 2 installed above the tooth opening. The pattern area A in FIG. 6 is knitted with the knitting yarn 7a fed from the yarn carrier 6a, and the pattern area B is knitted with the knitting yarn 7b fed from the yarn carrier 6b. In flat knitting machine 3 0, set up on thread stand 3 3 The knitting yarns 7 a and 7 b are fed from the cones 3 3 a and 3 3 b to the yarn carriers 6 a and 6 b with a substantially constant tension through the top spring device 3 4 and the yarn feeding device 35, respectively. To pay. At the start of knitting of the knitted fabric 9, the end of the knitting yarn is held by a dripper 36 provided at the end of the needle bed. When knitting the knitted fabric 9 in Fig. 6, even if the knitting of the X section in the wale direction is started, the end of the knitting yarn 7 b It is gripped by gripper 3 6. Accordingly, when the knitting of the end portion 28 is started, the position of the knitting yarn 7 supplied from the yarn carrier 6 b is a high position floating from the tooth opening 5. Therefore, in the knitting operation of the knit as shown in FIG. 4, it is difficult to capture the knitting yarn 7 in the hook 3a. However, the knit knitting operation as shown in FIG. As a result, the high knitting yarn 7 can be captured in the hook 3 a more reliably.

[0036] It should be noted that the need to capture the high-level knitting yarn 7 in the hook 3a is not only in knitting the Intarsia pattern, but also in floating knitting where the knitting needles are kneaded after making mistakes in the knitting needle. This also occurs when a new knitting of an independent knitted fabric area such as a pocket is started in the knitted fabric. Even in such a case, the knitting yarn 7 can be surely captured in the hook 3a by using the split increase.

8, FIG. 9 and FIG. 10 show a state in which the knitted fabric 9 in FIG. 6 finishes the X section in the wale direction and performs the knitting of the heel and heel sections. The numbers shown as courses on the left side of each figure indicate the relative course numbers. In the odd course, the carriage is moved to the left, and in the even course, the carriage is moved to the right. The symbol shown as a system on the right side of each figure indicates which one is used when three cam systems 10 as shown in FIGS. 2, 3, and 5 are mounted for each carriage 31. FIG. However, S 1 is the leading system, S 2 is the intermediate system, and S 3 is the trailing system. Therefore, when the carriage is on the left, the left cam system 10 becomes S 1 and on the right, the right cam system 10 becomes S 3, whereas when the carriage is on the right, the right cam system 10 becomes S 1. The left cam system 10 becomes S3. The use of the cam system is an example. Also, as shown in Figure 9, course 7 and course 8 are repeated. The number after course 9 does not mean the 9th or later course based on course 1.

[0038] In course 1, using the yarn carrier 6a indicated by a and the system S1, the final course knitting in the X section in the wale direction with the knitting yarn 7a is performed on the front needle bed 1. At the same time, use system S 2 to transfer from the front needle bed 1 to the rear needle bed 2 within the pattern area of A. The purpose of this transfer is to form a portion intersecting with the knitting yarn 7 a in the tooth opening 5. The position where the intersecting portion is formed is preferably near the end of the knitting width of the knitted fabric 9. When the crossing part is formed in the pattern area of A by rib knitting, etc., or the knitted fabric 9 is knitted into a bag shape, and the knitting that connects the front needle bed 1 and the back needle bed 2 at the end If the yarn is present, there is no need to form another intersection.

[0039] From course 2, start the first course formation in the Y section in the wale direction. The yarn carrier 6 b for feeding the knitting yarn 7 b stands by on the left side of the front needle bed 1 as shown in FIG. However, if the X section in the wale direction has already been knitted and the pattern area of B is also knitted in the X section, the knitting yarn 7 b is not the gripper 3 6 from the yarn feeder at the lower end of the yarn carrier 6 b. It is connected to the end of the knitted pattern area of B. In this state, when the system S 3 is used and the yarn carrier 6 b shown as b is taken to the right, the knitting yarn 7 b is hooked at the intersection formed in the course 1 and then fed to the end 2 8 in FIG. It is threaded. At the end 28, extra knitting is performed. As described above, since the split increase is used, even if the position of the knitting yarn 7 b fed from the yarn carrier 6 b is high, the knitting needle 3 can be reliably caught in the hook 3 a.

[0040] If the configurations and specifications of the yarn carrier 6 and the cam system 10 are different, it may be difficult to carry out an additional increase while carrying the yarn carrier 6b in the carriage 31. In such a case, the yarn carrier 6 b is first moved into the pattern area 9 yb of B on the right side of the carriage 31 and stopped. Although the position of the knitting yarn 7 b fed from the yarn carrier 6 b at the end 2 8 of the handle area 9 yb becomes higher, the yarn carrier 6 b is left and the carriage is left on the empty course 3 1 The knitting course may be divided so that the carriage 3 1 is moved to the left and the carriage 3 1 is moved to the right and the knitting yarn 7 b is captured by the hook 3 a by increasing the number.

[0041] In the course 3, the yarn carrier 6 b is moved to the left, the system S 1 is used, and the extra stitches in the knitting needle 4 in the rear needle bed 2 at the end portion 2 8 which has been increased in the course 2 are added. The stitch formation following the loop and the stitching on the knitting needle 4 of the adjacent A pattern area 9 ya are performed. The stitch loop added to the knitting needle 4 of the rear needle bed 2 due to the extra in the course 2 is knocked over and becomes the old loop.

[0042] In course 4, the yarn carrier 6 b is taken to the right with the system S 1 and the hook on the rear needle bed 2 is transferred to the front needle bed 1 with the system S 2. By pulling the knitting yarn 7 b in the opposite direction with the system S 1 and transferring it with the system S 2 against the hook, the end of the front needle bed 1 on the side of the pattern area of A Can be formed.

[0043] In the course 5, the yarn carrier 6 b is advanced to the pattern area side of the A in the system S 1, and the stitch transferred to the knitting needle 4 in the rear needle bed 2 in the course 1 is further knitted in the front needle bed 1. Transfer to return to. When splitting is performed to form the intersection, the stitch loop formed on the knitting needle 4 of the rear needle bed 2 is released and released. Since this intersection functioned as the starting point for thread placement, it was not necessary after course 2 was over.

[0044] In the course 6, following the hooking on the end of the adjacent A pattern region, the course knitting of the B pattern region is performed with the yarn carrier 6b taken along the system S1. In system S 2, yarn carrier 6a is taken and the pattern area of A is knitted. Furthermore, using the system S 3, the stitch loop that was increased in course 2 and held by the knitting needle 4 of the back needle bed 2 at the end 2 8 of the pattern area of B is connected to the knitting needle 3 of the front needle bed 1. Move to.

[0045] With the yarn processing from the course 2 to the course 6, the end portion 28 can be unwound. This unblocking is performed by using a stitch loop that has been increased by increasing the warp, but the method of unblocking is an example, and other methods are possible. [0046] If the unwinding is not performed, an additional stitch loop can be paid. Simply paying an extra stitch loop results in the formation of a stitch loop similar to a normal knitting, which can be used when the yarn feed position becomes higher due to yarn insertion or floating knitting. In addition, after the yarn insertion, after the stitch loop is formed on a knitting needle different from the knitting needle used for the additional split in the same knitting course, the increased stitch loop can be paid.

[0047] Further, once the stitch loop is transferred, the stitch is increased, and when a stitch loop newly formed by the premium is paid, the state before the transfer is returned as a result. For example, at the time of thread insertion to start knitting of the pattern area of B, the stitch loop at the end of the pattern area of A is transferred to increase the split, and the same knitting course as the split increase or the subsequent knitting After forming a stitch loop in the pattern area of B in the course and then paying a newly formed stitch loop at the end of the pattern area of A, the stitch loop in the pattern area of A is in the state before transfer Returning to step B, the thread insertion for knitting the pattern area B can be performed reliably.

[0048] In course 7 and course 8, the pattern areas of A and B are repeated and organized as many courses as necessary while taking yarn carriers 6a and 6b with systems S1 and S2.

[0049] In course 9, the last course knitting is performed in which the carriage is moved leftward and the pattern area A and the pattern area B are switched and knitted in the same course. Finally, in the system S 3, the stitch loop at the end 29 of the pattern area B is transferred from the knitting needle 3 on the front needle bed 1 to the knitting needle 4 on the rear needle bed 2.

[0050] In the course 10, the yarn carrier 6 b is taken back to the pattern area B by the system S 1.

[0051] In the course 1 1, the yarn carrier 6 b is connected to the pattern area side of the A in the system S 1, and the knitting needle on the second front needle bed 1 from the end 29 in the pattern area of the B The stitches on 3 and the stitches on the knitting needle 4 of the rear needle bed 2 of the end 2 9 are formed.

[0052] In the course 1 2, in the system S 1, the stitch loop formed on the knitting needle 4 of the back needle bed 2 at the end 29 of the pattern area of B is transferred to the knitting needle 3 of the front needle bed 1 . course With the yarn processing from 9 to the course 1 2, it is possible to prevent the end 2 9 from which the thread is removed from coming off. This unlocking is also an example and is not limited to this method.

In the course 1 3, the system S 1 is used to transfer from the knitting needle 3 of the front needle bed 1 to the knitting needle 4 of the rear needle bed 2 near the end of the knitting width in the pattern area A.

[0054] In the course 14, the yarn carrier 6 b is returned to the pattern area B.

[0055] In course 1 5, the yarn carrier 6 b is moved out of the knitting width of the knitted fabric 9 so as to move away from the pattern area of B while moving from the position of the stitch transferred in the course 1 3. Split the stitch loop transferred in 3 to the knitting needle 3 side of the front needle bed 1 and increase it. As a result, it is possible to reliably catch the transition yarn generated by the yarn being pulled out from the end portion 29 of the pattern area B in the vicinity of the knitting end of the knitted fabric 9 and to prevent the yarn from floating at the mouth 5.

In course 16, the yarn carrier 6 b is returned to a position closer to the pattern area side of B than the position of the knitting needles 3 and 4 where the splitting is increased.

[0057] In course 1 7, in system S 1, yarn carrier 6 b is taken and knitted

Hook the outside of the 9 knitting width. By increasing the cost of course 1 5, the crossover yarn is securely captured by the knitting needle 4, so that the stitches can be made reliably. In the system S 2, the stitch loop newly formed by increasing the course 15 is paid from the knitting needle 4 of the rear needle bed 2. The removed stitch loop is absorbed as a knitting yarn that is threaded around the outside of the knitted fabric 9. In addition, the stitch loop that has become the old loop of the newly formed stitch loop is the stitch loop transferred in the course 13 and a part of this stitch loop is increased by the extra in the course 15 Since it is hooked on the needle bed 1 side, it is absorbed by the stitch loop of the knitting needle 3 of the front needle bed 1, and as a result, the transfer in the course 1 3 is restored in the course 1 7.

[0058] In courses 1 8 and 19, the knitting of the pattern area A is repeated as many times as necessary for the Z section in the wale direction. The necessary course is that until the final thread is pulled down from the tooth opening 5 together with the knitted fabric 9 and no longer rises from the tooth opening 5 even if the outer stitch formed on the course 20 is removed. . [0059] In addition, after performing the extra increase in course 15 and then performing the knitting of the required number of courses and then paying the stitch loop from the knitting needle 4 of the back needle bed 2, the course 17 There is no need to form hooks and pay for course 20.

[0060] FIG. 11 shows the effect of forming an intersection in course 1 of FIG. FIG. 11 (a) shows a state in which the carriage 31 is traveling leftward on the course 1 with the yarn carrier 6 a. The yarn carrier 6 b supplying the knitting yarn 6 b stands by outside the knitting width of the knitted fabric 9. When the pattern area of B is knitted on the knitted fabric 9 in advance, the knitting yarn 7b is a crossover yarn from the yarn feeder at the lower end of the yarn carrier 6b.

[0061] FIG. 1 1 (b) shows a state in which the carriage is accompanied to the right by the yarn carrier 6 b in the course 2 after forming an intersection by transfer in the course 1 in FIG. The knitting yarn 7 b serving as a transition yarn is supplied for knitting the end portion 28 in FIG. 6 starting from the intersecting portion 40. In the case where the starting point 40 is not provided, at the time of knitting the end portion 28, the passing yarn is directly supplied from the end portion of the pattern area of B which has been knitted first. Since the position of the pattern area of B knitted earlier can be changed variously according to the needs of the knitted fabric 9 such as 9 b 1 and 9 b 2, the knitting conditions of the end portion 2 8 where the yarn is inserted also change. End up. If the starting point 40 is provided, the positional relationship of the transition yarn 7 b 0 from the starting point 40 to the end portion 28 is determined according to the positional relationship of the transition yarn 7 b 1, 7 from the handle region 9 b 1, 9 b 2 to the starting point 40 b Stabilizes even if the position of 2 changes, and can keep the knitting conditions constant

[0062] FIGS. 12 and 13 are schematic procedures of the concept of performing the trapping of the transition yarns as described above, and a design apparatus for generating knitting data including the procedures. The schematic structure is shown. As shown in FIG. 12, when the knitted fabric 9 shown in FIG. 6 is knitted by the flat knitting machine 30 shown in FIG. 7, it is input as pattern data in step s 1. In step s2, it is determined whether or not there is a section in which the knitting yarn 7 becomes a crossover yarn. When it is judged that there is a crossover thread, the crossover thread is captured by adding a split in step s3. If it is not judged in step s 2 that there is a crossover yarn, a regular knitting is performed.

[0063] As shown in FIG. 13, the design device 50 is connected to a general-purpose computer 51. It is realized by installing software for designing the knitted fabric. The installation can be performed by downloading via the communication device 54 or by attaching a recording medium to the external recording device 55. This software should also include a program that generates knitting data that captures the crossover yarn using the splitting procedure shown in Fig. 12. The computer 5 1 includes an input device 5 2 such as a keyboard, digitizer, and mouse, a display device 5 3 such as a graphic display, and a communication device 5 4 that can communicate with the outside via a LAN or the like. An external recording device 55 or the like to which a medium can be attached or detached is connected. The operator inputs the design data to the input device 52, and designs the knitted fabric 9 while observing the design result displayed on the display device 53. The operator gives an instruction to increase if the section to be used as the transition yarn becomes longer and it is difficult to catch the knitting needles 3 and 4 on the hooks 3a and 4a in a normal knitting operation. In response to this instruction, the computer 51 adds extra organization data. The knitting data to which the extra is added is transmitted to the flat knitting machine 30 via the communication device 54, or recorded on a recording medium such as a disk or USB memory from the external recording device 55, then the flat knitting. Input to machine 30 and knitting of knitted fabric 9 is performed.
