Technical Field
[0001] The present invention relates to a method for knitting a knitted fabric, a knitting program for causing a flat knitting machine to perform the knitting method for the knitted fabric, and a storage medium storing the knitting program. Background Technology
[0002] Patent Document 1 discloses a method for knitting a fabric to prevent the end yarns of the yarn inlet and outlet sections from coming loose. The yarn inlet section is the end of the knitted yarn that extends from the beginning loop of the knitted fabric section, which constitutes part of the fabric, toward the outside of the fabric. The yarn outlet section is the end of the knitted yarn that extends from the end loop of the knitted fabric section toward the outside of the fabric.

[0004] [Patent Literature]
[0005] [Patent Document 1] Japanese Patent Application Publication No. 2016-125162 Summary of the Invention
[0006] [The problem the invention aims to solve]
[0007] At the end of the knitting process on the flat knitting machine, the end yarn flies out towards the outside of the knitted fabric. This end yarn damages the appearance of the fabric. Previously, the end yarn was manually wrapped around the loops that make up the knitted fabric, making it less noticeable. However, this manual process was tedious and became a major reason for the reduced productivity of knitted fabrics.
[0008] In view of the above, one object of the present invention is to provide a knitting method for making knitted fabrics so that the end yarns can be wrapped around the fabric inconspicuously by a flat knitting machine. Another object of the present invention is to provide a knitting program for enabling the flat knitting machine to perform the above-described knitting method for the knitted fabric, and a storage medium storing the knitting program.
[0009] [Methods used to solve problems]
[0010] <1> The knitting method of the present invention uses a flat knitting machine to knit the fabric. The flat knitting machine includes a plurality of needle beds facing each other, a yarn feeder for supplying knitting yarn between the plurality of needle beds, and a movable clamp for holding the knitting yarn. The movable clamp is configured to move along the length of the plurality of needle beds. The knitting method of the knitted fabric includes: Step A: Weaving a first loop column that is part of the knitted fabric and connected to the end of the knitted yarn, i.e., the end yarn; In step B, before, during, or after step A, the end yarn is held by the movable clamp. Step C, before or after step A, involves using the end yarn to knit hook loops on an empty needle; Step D, following step C, involves weaving multiple segments of the second coil column connected in the longitudinal direction of the first coil column into the hook coil in a manner that allows them to be wound around the hook coil; and Step E, after step C, involves releasing the movable clamp from holding the end yarn. In step D, when knitting at least one segment of the multiple second loops using the yarn feeder, the yarn feeder is moved across the hook loop, and after the yarn feeder crosses the hook loop, the hook loop is moved toward the opposite needle bed, thereby winding the sinker arc of the second loop around the hook loop.
[0011] Here, the hook loop is a loop formed using a portion of the end yarn to process the end yarn, which would otherwise be a free end, on the flat knitting machine. Furthermore, the second loop column knitted in step D is directly or indirectly connected to the first loop column in the warp direction. That is, the second loop column can be knitted continuously in the warp direction of the first loop column, or at least one additional loop column can be knitted in the warp direction of the first loop column, and the second loop column can be knitted continuously in the warp direction of that additional loop column. Additionally, the relative needle bed in step D refers to the needle bed opposite to the needle bed where the hook loop is hooked before the yarn feeder traverses the hook loop.
[0012] Process E is preferably performed after processes A, B, and C, and before or during process D. The sequence of processes A through D, excluding process E, is as follows. The movable clamp can move independently of the yarn feeder, therefore process B, which uses the movable clamp, can also be performed during process A, which uses the yarn feeder.
[0013] • Process A → Process B → Process C → Process D
[0014] • Process A → Process C → Process B → Process D
[0015] • Process B → Process A → Process C → Process D
[0016] • Process B → Process C → Process A → Process D
[0017] • Process C → Process A → Process B → Process D
[0018] • Process C → Process B → Process A → Process D
[0019] <2> The above <1> The knitting method described can also include the following steps X and Y: Step X, following step A, involves continuously weaving additional coil columns in the longitudinal direction of the first coil column; In step Y, the movable clamp is moved in such a way that it traverses any one of the coils, i.e., the specific coil, in the additional coil array, and after the movable clamp traverses the specific coil, the specific coil is moved toward the opposite needle bed, thereby winding the end yarn around the specific coil.
[0020] <3> The knitting program of the present invention is a knitting program that can be read by a computer controlling a flat knitting machine. The flat knitting machine has a plurality of needle beds facing each other, a yarn feeder that supplies knitting yarn between the plurality of needle beds, and a movable clamp that holds the knitting yarn. The movable clamp is configured to move in a direction along the length of the plurality of needle beds. The knitting program of the present invention causes the flat knitting machine to perform the knitting method of the fabric described in <1> or <2> above.
[0021] <4> The storage medium of the present invention is a storage medium that stores the weaving program described in <3> above.
[0022] [Invention Effects]
[0023] In the knitting method of the present invention, after the hook loops are knitted using the end yarns, multiple segments of second loop rows are knitted while the end yarns are removed from the movable clamp. During the knitting of these multiple segments of second loop rows, the sinker arc of the second loop rows is wound around the hook loops, and the end yarns are wrapped around the second loop rows constituting the knitted fabric, making them inconspicuous. As shown in Embodiment 1 described later, as the number of second loop rows continuing in the warp direction increases, the hook loops unravel and the end yarns gradually elongate straight.
[0024] According to the knitting method of the fabric with process X and process Y, the end yarn is fixed by winding it around a specific loop, so the end yarn wrapped around the fabric is difficult to fall off the fabric.
[0025] According to the knitting program of the present invention, a flat knitting machine can implement the knitting method of the present invention for knitted fabrics. The computer executing the knitting program can be located on the flat knitting machine or connected to the flat knitting machine via wired or wireless means.
[0026] A flat knitting machine can implement the knitting method of the present invention by means of a storage medium storing the knitting program of the present invention. The storage medium can be equipped with the flat knitting machine when the knitting program is executed, or it can be connected to the flat knitting machine via wired or wireless means. The storage medium can also be a portable storage medium such as a USB memory. Attached Figure Description

[0051] Hereinafter, we will describe the knitting method, knitting procedure, and storage medium of the knitted fabric according to the embodiments based on the accompanying drawings.
[0052] <Implementation Method 1>
[0053] Knitted fabrics
[0054] Figure 1 The knitted fabric 5 of Embodiment 1 shown is a finger sleeve for a glove. A starting point 50 is formed at the fingertip portion of the finger sleeve. That is, the finger sleeve is knitted starting from the fingertip. The finger sleeve is knitted into a tubular shape using a flat knitting machine. The tubular knitted fabric 5 has a front knitted fabric portion 5F and a back knitted fabric portion 5B. Here, the knitted fabric 5 knitted by the knitting method of the present invention is not limited to finger sleeves, and can also be other tubular knitted fabrics. Other tubular knitted fabrics can be, for example, knitted items such as shorts or skirts, or industrial materials such as seat covers. The knitted fabric 5 is not limited to tubular knitted fabrics, and can also be a single-layer knitted fabric.
[0055] End yarn 3 extends from the beginning of the base 50. That is, in this example, end yarn 3 is the end yarn 3 of the yarn entry section. A cut end 30 is formed at the end of end yarn 3. The base 50 is composed of a first loop row 1 consisting of a series of loops connected to end yarn 3. End yarn 3 is concealed within the knitted fabric 5 and is inconspicuous. Based on Figure 2 The coil diagram illustrates the configuration of end yarn 3 in this example. Figure 2 Observe from the direction of the hollow arrow Figure 1 The diagram shows the loops of the knitted fabric 5, which is formed by the quadrilateral-enclosed portion. Separated by a single-dotted line, the left side represents the front knitted fabric portion 5F, and the right side represents the back knitted fabric portion 5B. The end yarn 3 extends straight along the warp direction (on the paper) of the knitted fabric 5, and is positioned to sew the knitted fabric 5 together. More specifically, regarding the end yarn 3, the following steps are repeated: at the position of the sinker arc connecting the front knitted fabric portion 5F and the back knitted fabric portion 5B, it passes from the outside to the inside of the tubular knitted fabric 5, and then at the position of the next sinker arc, it passes from the inside to the outside of the tubular knitted fabric 5. Unlike this example where the end yarn 3 is regularly positioned inside and outside the knitted fabric 5, the end yarn 3 can also be irregularly positioned inside and outside the knitted fabric 5.
[0056] Figure 2 The processing of the end yarn 3 shown is conventionally performed manually. The knitting method of the present invention allows this end yarn 3 processing to be performed on a flat knitting machine. Hereinafter, the structure of the flat knitting machine will be described first, followed by the knitting method of the present invention.
[0057] Flat knitting machine
[0058] Figure 3 This is a schematic diagram illustrating an example of a flat knitting machine 6 used to knit the aforementioned fabric 5. The flat knitting machine 6 is a two-bed flat knitting machine equipped with a pair of needle beds 6B arranged opposite each other in the depth direction of the paper. The pair of needle beds 6B are also referred to as the front needle bed (hereinafter referred to as FB) and the back needle bed (hereinafter referred to as BB), respectively. The flat knitting machine 6 is equipped with a transverse movement mechanism 65 that offsets the relative positions of FB and BB along the length of FB and BB. The transverse movement mechanism 65 can utilize a known structure. The flat knitting machine 6 used to knit the fabric 5 can also be a four-bed flat knitting machine equipped with a lower front needle bed, a lower back needle bed, an upper front needle bed, and an upper back needle bed.
[0059] Multiple knitting needles are arranged side-by-side on the needle bed 6B. These needles are driven by a cam system mounted on a cam carriage 6C that reciprocates on the needle bed 6B. The cam system includes a loop transfer mechanism 66, i.e., a loop transfer cam, that moves the loop between FB and BB. The knitting needles can be latch needles with opening and closing hooks, or composite needles with opening and closing hooks. The flat knitting machine 6 also includes multiple yarn feeders 6F that supply knitting yarn 6Y to a toothed opening formed between a pair of needle beds 6B. Each yarn feeder 6F is mounted on any one of multiple tracks 6R and travels along the tracks 6R. The multiple tracks 6R extend above the needle beds 6B and parallel to the needle beds 6B. The knitting yarn 6Y is supplied from the antenna assembly 6T to the yarn feeders 6F via a side tensioning device (not shown).
[0060] The end of the knitting yarn 6Y supplied from the front end of the yarn feeder 6F, i.e., the end yarn 3, is held by a fixing clamp 6H located on the outside of the needle bed 6B before new knitting begins. The end yarn 3 is held by the fixing clamp 6H, thereby drawing the knitting yarn 6Y out of the yarn feeder 6F when the yarn feeder 6F is moved. The knitting yarn 6Y drawn out from the yarn feeder 6F extends along the teeth between FB and BB. By hooking the knitting yarn 6Y extending along the teeth using a knitting needle, loops can be knitted on the needle bed 6B. In this example, the fixing clamp 6H is located at one end along the length of the needle bed 6B, but it could also be located at both ends.
[0061] The flat knitting machine 6 in this example includes a movable clamp 6G for holding the knitting yarn. The movable clamp 6G is configured to move along the length of the needle bed 6B. Therefore, the movable clamp 6G can move along the direction of the needle bed 6B while holding the knitting yarn 6Y. The movable clamp 6G can be a known movable clamp, such as the movable clamp described in International Publication No. 2009 / 084193. Alternatively, a cutting tool for cutting the held knitting yarn 6Y can be integrally formed on the movable clamp 6G.
[0062] The flat knitting machine 6 is equipped with a computer 60 for controlling the flat knitting machine 6. The control of the flat knitting machine 6 includes controlling the movement of the triangular carriage 6C, the movement of the triangular system mounted on the triangular carriage 6C, and the movement of the yarn feeder 6F.
[0063] Computer 60 includes processor 61 and storage medium 62. Processor 61 is any processor suitable for controlling computer 60. Processor 61 is, for example, CPU (Central Processing Unit), GPU (Graphics Processing Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), etc.
[0064] Storage medium 62 stores a knitting program for causing the flat knitting machine 6 to knit the fabric 5. In this example, the knitting program contains instructions for causing the flat knitting machine 6 to perform the knitting method described later. The processor 61, described above, causes the flat knitting machine 6 to perform the knitting operation by executing the instructions of the knitting program.
[0065] Unlike this example, the computer that controls the knitting machine 6 based on the knitting program in this example can also be another computer connected to the knitting machine 6 via a network such as LAN (Local Area Network), WAN (Wide Area Network), or the Internet.
[0066] [Knitting Methods for Fabrics]
[0067] based on Figure 4 and Figure 5 Weaving process diagram and Figure 6 The loop diagram illustrates the specific knitting method of fabric 5 using the aforementioned flat knitting machine 6. Figure 4 and Figure 5 In the diagram, FB and BB are indicated by thick lines. The uppercase letters outside the top column indicate the position of the knitting needles. "S + number" in the left column indicates the knitting sequence number. Straight arrows indicate the direction of loop movement or the direction of movement of the movable clamp 6G.
[0068] exist Figure 4 In step S1, it indicates that after the yarn is inserted, the bottom 50 is woven (refer to...). Figure 1 The first loop column 1 (corresponding to step A) is then continued in the longitudinal direction of the first loop column 1 to knit a tubular additional loop column 10 (corresponding to step X). The first loop column 1 is a serrated loop column (not shown) with loops alternately formed on FB and BB. In step S1, the first loop column 1 has been removed from the needle bed 6B. Here, yarn feeding refers to the operation of moving the yarn feeder 6F to introduce the knitting yarn 6Y from the outside of the knitting range of the starting bottom 50 toward the knitting range. In this example, the yarn is fed from the right side of the paper toward the left side to knit the first loop column 1 that constitutes the starting bottom 50.
[0069] In this example, at step S1, the movable clamp 6G holds the end yarn 3 connected to the first coil 1 during the yarn insertion process (equivalent to step B). After holding the end yarn 3 with the movable clamp 6G, the fixed clamp 6H is released. Figure 3 The end yarn 3 is held in place. Since the fixed clamp 6H holds the cut end 30 of the end yarn 3, the cut end 30 of the end yarn 3 is released from holding and becomes a free end. Unlike this example, if the movable clamp 6G has a cutter, the end yarn 3 can also be cut by the cutter of the movable clamp 6G.
[0070] In steps S2 to S5, the end yarn 3 is wound onto the end loop 4 of the additional loop column 10 hooked to the needle E of BB (equivalent to step Y). In this example, the end loop 4 is the end loop on the side where the end yarn 3 is located.
[0071] In step S2 of process Y, the specific loop 4 hooked on needle E of BB is moved towards needle F of FB. In step S3, the movable clamp 6G is moved to the left so that it passes through the specific loop 4. In step S4, the specific loop 4 is returned to needle E of BB. The end yarn 3 is wound around the outside of the specific loop 4. In step S5, the movable clamp 6G is moved to the right so that it passes through the specific loop 4. The end yarn 3 is wound around the inside of the specific loop 4. Through this series of processes, the end yarn 3 is wound around the specific loop 4.
[0072] In this example, steps S2 to S5 are repeated again. The result is a state where the end yarn 3 is wound twice on a specific loop 4. Based on... Figure 6 The coil diagram illustrates the state of end yarn 3 wound around a specific coil 4. Figure 6 The diagram only shows the portion of knitted fabric 5 woven in BB. The portion of knitted fabric 5 connected to the portion woven in FB is indicated by dashed lines. End yarn 3 is indicated by thicker yarn. The portion of end yarn 3 opposite to the cut end 30... Figure 1 The bottom 50 connection. For example... Figure 6 As shown, at the end of the second step S5, the end yarn 3 is wound around the specific coil 4 in a manner that surrounds the specific coil 4.
[0073] In this example, after step S5 in the second iteration, the process is repeated once more. Figure 4 The weaving of steps S1 to S5. The result is as follows: Figure 6As shown, the second additional loop train 10 is woven, and the end yarn 3 is wound onto a specific loop 4 of the second additional loop train 10. The more times the end yarn 3 is wound onto the specific loop 4, the more weaving steps there are, but the more firmly the end yarn 3 is fixed to the knitted fabric 5. As a result, the end yarn 3 is difficult to fall off the knitted fabric 5. The number of windings is not limited, but is preferably about 2 to 3 times. Of course, the number of windings can also be 1 time.
[0074] exist Figure 5 In step S10, the end yarn 3 is used as an empty needle to knit hook loop 33 (equivalent to step C). In this example, the hook loop 33 is knitted on an empty needle located outside the knitting range of the additional loop column 10 by moving the movable clamp 6G. More specifically, the movable clamp 6G is moved to knit a twisted loop 31 on needle F of BB, followed by a twisted loop 32 on needle G of BB, and finally the hook loop 33 is knitted by continuing in the longitudinal direction of the loop 31. The loop 32 is used to increase the size of the hook loop 33 by removing it from the needle bed in a later step, and is not necessary. If the hook loop 33 is large, it is easier to move the hook loop 33 between FB and BB.
[0075] The hook loop 33 needs to eventually unravel as described later. Therefore, the hook loop 33 needs to be independent of the loops constituting the knitted fabric 5, that is, it needs not to be connected to the loops constituting the knitted fabric 5 in the warp direction. Unlike this example, the hook loop 33 can also be formed at a position that overlaps with the knitting range of the first loop column 1. For example, in the case of pulling stitches in the first loop column 1, the hook loop 33 can also be knitted on an empty needle located between two adjacent loops in the first loop column 1.
[0076] In step S11, the loop 32 is removed from the needle bed, and the movable clamp 6G releases the grip on the end yarn 3 (equivalent to step E). In steps following step S11, for ease of observation of the accompanying drawings, the state of the end yarn 3 near the hook loop 33 is simplified.
[0077] In steps S12 to S14, with the movable clamp 6G releasing the grip on the opposite yarn 3, multiple segments of the second loop 2 connected in the longitudinal direction of the first loop 1 are woven over the additional loop 10 (equivalent to step D). In this example, two segments of the additional loop 10 are woven continuously in the longitudinal direction of the first loop 1, therefore the second loop 2 is woven continuously in the longitudinal direction of the second additional loop 10. Alternatively, unlike this example, the grip on the opposite yarn 3 of the movable clamp 6G may be released midway between steps S12 and S14.
[0078] In step S12 of this example constituting process D, the hook loop 33 of the needle F hooked to BB is moved toward the needle F of FB. In step S12, the yarn feeder 6F is further moved to the right to knit the second loop 2 that continues in the longitudinal direction of the additional loop column 10 hooked to BB. The yarn feeder 6F moves to a position that crosses the hook loop 33, that is, to the right of the hook loop 33.
[0079] In step S13, the hook loop 33 of the needle F hooked to FB is returned to the needle F of BB. In step S13, the yarn feeder 6F is further moved to the left to knit the second loop 2 continuing in the longitudinal direction of the additional loop column 10 hooked to FB. The yarn feeder 6F moves to a position traversing the hook loop 33, i.e., to the left of the hook loop 33. The sinker arc 20 connecting the right end of the second loop column 2 hooked to BB and the right end of the second loop column 2 hooked to FB is wound around the hook loop 33 in a manner that hooks onto the hook loop 33 and folds back. In other words, as... Figure 5 As shown, the hook loop 33 is disposed inside the tube of the second loop column 2, which is in the shape of a tube, that is, inside the tube-shaped knitted fabric 5.
[0080] Alternatively, unlike this example, in each of steps S12 and S13, the order of weaving the second loop 2 and moving the hook loop 33 can be reversed. Specifically, in step S12, the yarn feeder 6F moves to the right, weaving the second loop 2 on BB. At this time, the yarn feeder 6F moves to the right of the hook loop 33, whereby the knitting yarn 6Y crosses the FB side of the hook loop 33. Then, the hook loop 33 moves toward the needle F of FB. In the next step S13, the yarn feeder 6F moves to the left, weaving the second loop 2 on FB. At this time, the knitting yarn 6Y extending from the yarn feeder 6F crosses the BB side of the hook loop 33. Then, the hook loop 33 returns to the needle F of BB. In this case, the sinker arc 20 extending from the second loop 2 hooked on BB crosses the FB side of the hook loop 33 and wraps around the hook loop 33, then crosses the BB side and connects with the second loop 2 hooked on FB. That is, when viewed from above the toothed opening, the sinking arc 20 becomes a twisted ring shape, and a hook coil 33 is arranged on the inner side of the ring.
[0081] Through the above steps S12 and S13, one section of the second coil column 2 is woven, thus starting from the bottom 50 ( Figure 1 (It) descends downwards. For example... Figure 6 As shown, the end yarn 3 is connected to the bottom 50 and is pulled by the downward-moving bottom 50. The end yarn 3 is not held by the movable clamp 6G, so the hook loop 33 and the hanging loop 31 formed by the end yarn 3 begin to unravel.
[0082] In step S14, the second coil column 2 is woven around the yarn in a circular loop. Specifically, the yarn feeder 6F is moved to the right, and the second coil column 2 is woven in BB. Then, the yarn feeder 6F is moved to the left, and the second coil column 2 is woven in FB. The sinker arc 21 connecting the coil hooked to the right end of the second coil column 2 at BB and the coil hooked to the right end of the second coil column 2 at FB in step S14 is not wound around the hooked coil 33. Therefore, as Figure 6 As shown, the hook loop 33 is arranged on the outside of the tube of the second loop column 2 in the shape of a tube, that is, on the outside of the tube-shaped knitted fabric 5.
[0083] In step S14, a new second coil column 2 is also woven, thus the bottom 50 descends further downwards. Therefore, as... Figure 6 As shown, the end yarn 3 is pulled further downwards to loosen the hook loop 33 and the hanging loop 31.
[0084] Then, repeat steps S11 to S14 of the weaving process. As the number of the second loop column 2 increases, the hook loops 33 unravel, and the end yarn 3 gradually extends straight. Finally, as... Figure 2 As shown, the straight-extending end yarn 3 becomes wound around the knitted fabric 5. This state is achieved by the knitting of the flat knitting machine 6, eliminating the need for manual operation. Therefore, the productivity of the knitted fabric 5 is greatly improved.
[0085] <Variation Example 1>
[0086] The hook loop 33 in Embodiment 1 can also be formed during yarn feeding. Specifically, the yarn feeder 6F is moved toward the weaving range of the first loop column 1 to form the hook loop 33 (equivalent to step C), and then the yarn feeder 6F is moved to weave the first loop column 1 (equivalent to step A). Afterwards, if implemented... Figure 5 The weaving process shown is as follows: Figure 2 As shown, a knitted fabric 5 is formed by weaving straight, extended end yarns 3 around the knitted fabric 5.
[0087] Here, step B, in which the movable clamp 6G holds the end yarn 3, can be performed before step A, during step A, or after step C. If step B is performed before step A, weaving can begin while the end yarn 3 is being held by the movable clamp 6G instead of the fixed clamp 6H. That is, weaving can also begin after step B. In this case, the switching of the end yarn 3 from the fixed clamp 6H to the movable clamp 6G, as shown in Embodiment 1, is omitted.
[0088] <Implementation Method 2>
[0089] In Embodiment 1, an example was described of processing the end yarn 3 generated during yarn feeding using the knitting method of the present invention. The knitting method of the present invention can also be used to process the end yarn 3 generated during yarn exit. Based on... Figure 7 and Figure 8 Here is one example.
[0090] Figure 7 The knitted fabric 5 shown includes a first knitted section 51, a second knitted section 52, and a third knitted section 53 that are continuous in the warp direction. These knitted sections are knitted from different knitting yarns. The first knitted section 51 has an end yarn 3A at the yarn inlet and an end yarn 3B at the yarn outlet. The second knitted section 52 has an end yarn 3C at the yarn inlet and an end yarn 3D at the yarn outlet. The third knitted section 53 has an end yarn 3E at the yarn inlet and an end yarn 3F at the yarn outlet. The end yarns 3A, 3C, and 3E at the yarn inlet can be processed according to the knitting process of Embodiment 1. The end yarn 3F of the third knitted section 53 can be processed, for example, by hand. On the other hand, the end yarns 3B and 3D at the yarn outlet can be processed according to... Figure 8 The weaving process shown is performed.
[0091] Figure 8 This is a schematic diagram of the weaving process for processing the end yarn 3B of the yarn outlet. Figure 8 Observation methods and Figure 4 Same. However, in Figure 8 The diagram of the needle bed is omitted.
[0092] In step S20, the state of the first loop column 1, which is the final loop column of the first knitted fabric section 51, is indicated, which is the state of the end of process A. The knitting yarn 6Y extending from the last loop of the first loop column 1 to the yarn feeder 6F is the end yarn 3B of the yarn exit section.
[0093] In step S21, the movable clamp 6G holds the knitting yarn 6Y (step B) and cuts the held knitting yarn 6Y. The cutting of the knitting yarn 6Y can be performed by a movable cutter or by a cutter equipped on the movable clamp 6G. In the next step S22, the movable clamp 6G holding the yarn end 3 is moved to weave the hook loop 33 (equivalent to step C). In step S23, the movable clamp 6G releases its grip on the yarn end 3B (equivalent to step E).
[0094] After step S23, begin Figure 7 The second knitted section 52 is knitted. During the knitting of the second knitted section 52, the following is performed: Figure 5 The weaving process shown is equivalent to process D. That is, in embodiment 2, Figure 5 The second loop row 2 shown constitutes the second knitted fabric section 52. According to the knitting process of this example, the end yarn 3B of the yarn exit section is wrapped around the structure of the second knitted fabric section 52 and becomes inconspicuous.
