Abstract

A method of knitting a fabric capable of stabilizing knitting and reducing labor in a treatment step after the knitting by eliminating such a defect that a crossed yarn remains, in a loosened state, on a trick gap part in a non-knitted district. A knitting yarn (11b) is tacked and arrested by the knitting needle (9) of a needle bed (2) on a side not engaged in knitting. Also, the stitches of the fabric (10) are transferred to retain the crossed yarn near the end of the district. After the stitch transfer, the arrested knitting yarn (11b) is released from the knitting needle (9) of the needle bed on the rear side. In this stitch reduced state, the knitting yarn (11b) forming the crossed yarn is loosened since it is released in a pulled-in state at the time of arresting. The loosening of the loosened knitting yarn (11b) is removed by advancing a yarn carrier (5b) in the same direction as or the reverse direction to a moving direction.

Description

Knitting method of knitted fabric

Technical field

[0001] The present invention relates to a knitting method of a knitted fabric including a section where crossover yarn is generated using a flat knitting machine.

Background art

Conventionally, when a knitted fabric is knitted for each course with a flat knitting machine, a pattern knitted fabric such as an intarsia pattern or an argyle pattern can be obtained by using a plurality of knitting yarns in one course. Yes (for example, see Japanese Examined Patent Publication No. 61-51061). A multicolored pattern knitted fabric can be obtained by using different colors of knitting yarns for intarsia patterns. However, among the knitting yarns of multiple colors, there is a transition yarn that is not used for knitting in a section of one course, exists on the mouth of the mouth in a loose state, and floats on the knitted fabric force knitted in that section Arise.

In the section where the transition yarn remains floating, the knitting needle that performs the knitting movement at the mouth of the knitted fabric to knit the knitted fabric is accidentally knitted with the transition yarn hanging around it, or the knitting needle knitting operation is disturbed by the knitting needle There is a risk of becoming. In addition, when knitting of the knitted fabric that uses the knitting yarn that is used as the transition yarn after the section that becomes the transition yarn is started, it is necessary to ensure that the knitting needle for knitting the fabric is hooked. There is also. If the section where the crossover yarn floats is long, the position of the knitting yarn to be fed may go out of the range of the knitting needle.

In order to prevent such problems caused by crossover yarn, a method is known in which a knitting yarn that becomes a crossover yarn is knitted and fixed to a knitted fabric that is not originally used for knitting. In a flat knitting machine in which two needle beds are arranged opposite to each other, the transition yarn is not used for knitting, but is captured by the knitting needles on the heel side needle bed, and the movement of the knitting needles involved in the knitting of the knitted fabric is performed. There is also a method of evacuating from the area (see, for example, JP-A-7-310262 and JP-A-9-31802).

In Japanese Patent Laid-Open No. 7-310262, the transition yarn is generated in a section where the knitting needle on the side of the needle bed not used for knitting of the knitted fabric is used to catch the transition thread on the hook, and then at least the section Until the knitted fabric is knitted, a technique is disclosed in which the trapped transition yarn is retracted from the movement region in the knitting operation of the knitting needle related to the knitted fabric. Captured thread Is then removed from the knitting needle after the transition yarn is generated and captured. However, it is also described that the trapped jump yarn may be removed before the next trapping of the jump yarn. It is stated that it is preferable that the last transition yarn generated should continue to be caught until a harmful effect occurs even when knitting with a different yarn is started.

In JP-A-9-31802, as in JP-A-7-310262, a transition yarn is not used for knitting the knitted fabric, but is captured by the knitting needle on the side needle bed and becomes a transition yarn. After knitting the knitted fabric using the yarn using at least the first knitting needle, transfer some stitches of the knitted fabric to the empty needle near the knitting needle that captures the transition yarn. After pressing the crossover thread, remove it from the knitting needle that catches the crossover thread and scoops it. Next, the transferred stitch is returned to the knitted fabric. There is also a method in which the knitting needle that is not used for knitting the knitted fabric is advanced to the area where the crossover yarn is supplied, and the crossover yarn is caught and guided under the hook of the knitting needle without pressing the crossover yarn. This is disclosed (for example, see JP-A-9-31804).

As described above, when a floating yarn with a knitted fabric force is generated, there is a possibility that the knitting of the knitted fabric may be hindered. When the crossover yarn is knitted into the knitted fabric by tack knitting, it is necessary to cut the crossover yarn and remove it from the knitted fabric in a subsequent process, which is troublesome.

In the methods disclosed in Japanese Patent Laid-Open Nos. 7-310262 and 9-31802, if the transition yarn is captured and then removed from the knitting needle, the removed knitting yarn is loosened. In paragraph [0021] of the specification of Japanese Patent Application Laid-Open No. 7-310262, the transition yarn is captured and held so that when the transition yarn is removed, the tension is easily moved in the winding direction of the knitted fabric. It is disclosed that it is preferable to lengthen the period. However, if the period for capturing and holding the transition yarn is lengthened, the knitted fabric following that period will be knitted. However, since it is necessary to continue catching the crossover yarn using a knitting needle, the knitting needles used for knitting the subsequent knitted fabric are limited, and the knitted pattern is restricted. In particular, when knitting the knitted fabric is automated, it is required to complete the process as a series of steps for each course of the knitted fabric to be knitted. This is because the knitting conditions for one course in the knitted fabric are not completed, and the knitting process for the subsequent course and the process for completing the incomplete course are complicated. In addition, the transition yarn may move upward (rising up) at the mouth according to the knitting operation of the knitting needle during the holding period of being captured by the knitting needle. JP-A-9 In the method disclosed in Japanese Patent No. 31802, the crossover yarn is caught! When the stitch that has been pressed by transfer and returned to the knitted fabric is returned to the knitted fabric, the crossover yarn is floated and near the mouth May cause problems in the organization of the next course.

In the method disclosed in Japanese Patent Laid-Open No. 9-31804, the operation of a yarn carrier that supplies a knitting yarn that becomes a transition yarn and the knitting operation that a knitting needle performs with respect to the supplied knitting yarn are combined with a normal knitting operation. Therefore, it is necessary to carry out at a timing different from the case where the knitting yarn is applied to the hook of the knitting needle. For flat knitting machines in which the carriage moves back and forth along the needle bed and the knitting needles perform knitting operations with cams mounted on the carriage and the carriage carries the yarn carrier force. Is difficult. In a flat knitting machine in which the yarn carrier can move independently of the carriage, or a flat knitting machine in which the knitting needles can be driven individually, the control is complicated even if the timing can be changed.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1A is a front view schematically showing a schematic configuration of a flat knitting machine 1 used for knitting a knitted fabric as one embodiment of the present invention, and FIG. 1B is an example of a knitted fabric to be knitted. Shown in simplified plan view. The flat knitting machine 1 is provided with a pair of front and back needle beds 2, which are opposed to each other with an intermediate tooth gap interposed therebetween. In the longitudinal direction of the needle bed 2, the carriage 3 reciprocates. Above the needle bed 2, a yarn path rail 4 is provided. Along the yarn path rail 4, a plurality of yarn carriers 5a, 5b, 5c (hereinafter, the components related to each yarn carrier 5a, 5b, 5c are indicated by reference numerals a, b, c respectively. In addition, when the components are collectively referred to, the reference marks are indicated by removing a, b, and c). The yarn path rail 4 is provided with a plurality of paths, and each yarn carrier 5a, 5b, 5c can run independently. Yarn carrier 5 is selectively entrained by carriage 3. In the figure, a state in which the yarn carrier 5b is carried by the carriage 3 is shown. The yarn carrier 5b is supplied with knitting yarn from the yarn feeding mechanism 6b. The yarn feeding mechanism 6b is supplied with knitting yarn from a cone 7b provided in the upper part of the flat knitting machine 1 or the like. Although not shown, the yarn carriers 5a and 5c are the same as the yarn carrier 5b.

The movement of the carriage 3 is controlled by the control device 8 and is performed according to knitting data created in advance. A large number of knitting needles 9 are arranged on the needle bed 2 in parallel. Each knitting needle 9 is selectively driven by a cam mechanism mounted on the carriage 3. The selected knitting needle 9 advances to the tooth mouth and performs a knitting operation for knitting the knitted fabric 10. The knitting needle 9 performing the knitting operation is entrained in the carriage 3 and supplied with 1 lb of knitting yarn from the yarn carrier 5b. In the supply path of the knitting yarn l ib from the cone 7b to the yarn carrier 5b, a top spring mechanism 12b and a side tension mechanism 13b for applying an appropriate tension to the knitting yarn l ib are provided as the yarn feeding mechanism 6b. A gripper (not shown) is provided at the end of the needle bed 2, and holds the tip of the knitting yarn 1 lb supplied from the yarn carrier 5b. In the first stage of knitting the knitted fabric 10 using 1 lb of knitting yarn, 1 lb of knitting yarn extending from the gripper holding the tip to the yarn carrier 5b yarn feeder is applied to the knitting needle 9 at the tooth mouth near the yarn feeder. Knitting is performed on the hook. The knitted fabric 10 to be knitted hangs downward from the tooth opening every time the course is knitted.

FIG. 1B shows, in a simplified manner, an example of a knitted fabric 10 that is knitted using the yarn carriers 5a, 5b, and 5c. The knitted fabric 10 is divided into two ranges, X and Y, as the course formation progresses. Is organized. Among these, in the previous X range, the knitted fabric A is knitted using the knitting yarn supplied from the cone 7a through one yarn carrier 5a over the entire knitting width. In the latter Y range, the knitting width is divided into three sections, and each section is knitted fabric A, B using knitting yarns supplied from the cones 7a, 7b, 7c via the yarn carriers 5a, 5b, 5c, respectively. , C is organized. Even when the knitted fabric A and the knitted fabric C knitted in two separate sections in the Y range use the same knitting yarn, it is preferable to use the yarn carriers 5a and 5c separately. This is because if the same yarn carrier 5 is used, the processing in the middle section becomes complicated. Hereinafter, the knitted fabrics A, B, and C in the Y range are shown as sections A, B, and C, respectively.

As shown in Fig. 1A, when the yarn supply force at the lower end of the yarn carrier 5b is fed to the knitting needle 9 of the needle bed 2, the tip of the knitting yarn 1 lb is held by the gripper at the left end of the needle bed 2. In the Y range, the knitting yarn l ib becomes the crossover yarn in the A section. In addition, the knitting yarn supplied from the yarn carrier 5c becomes a transition yarn in the A section and the B section. Since such a transition yarn is present in the mouth of the knitted fabric 10 in a loosened state floating from the knitted fabric 10, there is a possibility that the above-described problems may occur when the knitted fabric 10 is knitted.

A knitted fabric 10 as shown in FIG. 1B is knitted mainly using one side of the front and back needle beds 2. In this embodiment, the knitting yarn that becomes the transition yarn is drawn in and captured by the knitting needle 9 of the needle bed 2 on the side that is not involved in knitting. For example, if the knitted fabric 10 is mainly knitted on the front needle bed and the knitting yarn l ib becomes a crossover yarn in the A section in the Y range, the knitting needle 9 on the rear needle bed is appropriately selected in this A section. Then, tap the knitting yarn l ib to catch it. Next, the stitches of the knitted fabric 10 locked by the front needle bed are transferred and the crossover yarn is pressed. The yarn carrier 5b that has supplied the knitting yarn l ib to the knitting needle 9 in this A section stops in a state where it has shifted to the next B section of this A section. Next, the captured knitting yarn l ib is released from the knitting needle 9 on the rear needle bed. The knitting yarn l ib that becomes the crossover yarn in this state of stitching is pulled and tensioned at the time of catching, so that it loosens when the pulling is released by stitching. Since the loose knitting yarn l ib may interfere with the knitting of the knitted fabric in this section A, the yarn carrier 5b that supplies the knitting yarn l ib is moved in the direction in which the crossover yarn is generated. The slack can be removed by moving it further in the same direction as or in the opposite direction. The yarn carrier 5b can be reciprocated to remove slack multiple times.

For yarn inserts that start knitting of the knitted fabric in section B using knitting yarn l ib, the yarn carrier Feed the yarn from 5b and knit the knitted fabric 10. The left end of the knitting yarn l ib is held down by the previously transferred stitch, so that the yarn feeding height at the first knitting needle 9 in the B section is an appropriate height, and knitting is performed with the yarn biting reliably performed. Can start. If there is no presser at the stitch, the left end of the knitting yarn l ib will be held by the gripper at the left end of the needle bed 2 and will be at a position away from the first 9 knitting needles in section B.

Since the lower end of the yarn carrier 5 is located above the range where the knitting needle 9 performs the knitting operation at the tooth opening, the yarn supplying force at the lower end of the yarn carrier 5 is supplied to the knitting yarn 11 immediately after being supplied. The position is too high to hook the hook at the tip of the knitting needle 9. The carriage 3 entrains the yarn carrier 5 so as to precede the moving direction of the knitting needle 9 that performs the knitting operation by the mounted cam mechanism. If the tip of the knitting yarn 11 that is also supplied with the yarn feed port force of the yarn carrier 5 and is only held by the gripper is held by the gripper, the knitting that extends to the force near the yarn feed port of the yarn carrier 5 as it moves away from the gripper The inclination angle of the yarn 11 becomes small, and the position of the knitting yarn 11 near the yarn feeder becomes high. If the crossover yarn is held by the stitches in section A, the inclined position of the knitting yarn 11 that extends to the yarn feeder of the yarn carrier 5 also increases, and the position of the knitting yarn 11 near the yarn feeder is lowered. be able to.

When knitting with the knitting yarn l ib in section B is started, the knitting yarn l ib supplied to the knitting needle extends from the knitting needle 9 forming the stitch of the knitted fabric 10 to the yarn feeder of the yarn carrier 5b. Thus, the next knitting needle 9 can be supplied at a sufficiently low position. After that, the stitches that were transferred in Section A are returned to the original knitting needles on the knitting side. After that, the organization will continue.

As described above, transition yarn processing in section B is performed in the following series of steps.

Capture → Transfer → Payout! ゝ → Remove slack

FIG. 2 and FIG. 3 show the transition yarn processing procedure when the knitted fabric 10 shown in FIG. 1B is knitted. a, b and c show the yarn carriers 5a, 5b and 5c in FIG. The X range is organized using only the yarn carrier 5a. It is assumed that the carriage 3 that selectively carries the yarn carriers 5a, 5b, and 5c is equipped with two systems of cam mechanisms that cause the knitting needle 9 to perform a knitting operation. Further, in the X range, the yarn carriers 5 b and 5 c that are not used for knitting are kept waiting at a position outside the knitting width of the knitted fabric 10. In step SI shown in FIG. 2, the final course in the X range is knitted with the knitting yarn supplied from the yarn carrier 5a using, for example, the knitting needle of the front needle bed. Next, in step S2, the first course organization in the Y range is started. First, threading in section C is performed. The yarn carrier 5c generates a cross yarn in the A section and the B section and moves to the C section. In Section A and Section B, use the knitting needles on the rear needle bed that have not been knitted in Step S1 as appropriate to tack, catch the transition yarn, and lower the tooth locus. In the vicinity of the end of section B, the knitted fabric force stitch locked to the knitting needle on the front needle bed is transferred to the rear needle bed, and the crossover yarn is pressed. It is preferable that the stitch to be transferred is close to the section where the yarn is inserted. However, if it is within the range of about 1 to 3, the cross stitch is surely pressed, and at the start of knitting in the next section, The knitting yarn can be reliably hung on the knitting needle.

Next, in step S 3, the stitching is performed to release the crossover yarn captured by the tack on the knitting needle on the back needle bed in step S 2. Since the crossover thread that has been perforated has been pulled down from the mouth by the knitting needle 9, loosening occurs. However, since the stitches are held by the transferred stitch, the tooth locus does not rise at least near this stitch. In the next step S4, the carriage 3 is further moved into the section C, the yarn carrier 5c is entrained, and the released transition yarn is pulled. Further, in step S5, the yarn carrier 5c is moved in the reverse direction by the carriage, and is repeated. Step S4 and step S5 may be repeated a plurality of times.

As shown in FIG. 1A, the supply path of the knitting yarn 11 is provided with a yarn feeding mechanism 6 such as a top spring mechanism 12 and a side tension mechanism 13 that apply tension to the knitting yarn 11. By reciprocating the yarn carrier 5 in step S4 and step S5, the wefted transfer yarn is surely tensioned and loosened by the yarn supplying mechanism 6.

Next, in step S6, the stitches in section C are knitted using the knitting yarn supplied from the yarn carrier 5c. At this stage, in the B section adjacent to the C section, the transition yarn is held by the stitch that has been transferred, so the position of the knitting yarn is lowered even near the yarn feeder of the yarn carrier 5c, and it is surely applied to the knitting needle 9. Can be in a state of thread-eating. In order to join the knitted fabric knitted in the C section with the knitted fabric knitted in the B section, the knitting yarn is applied to the adjacent knitting needles 9 in the B section and tacked before the knitting in the C section. The knitted fabric of section C is knitted. When one or more stitches in section C are knitted, they are transferred to section B for the purpose of ensuring thread evacuation. Therefore, in step S7, the stitch is transferred from the back needle bed back to the front needle bed.

Next, the process proceeds to step S8 in Fig. 3, and yarn insertion in the B section is performed using the yarn carrier 5b. Since the knitting yarn supplied from the yarn carrier 5b becomes a crossover yarn in the A section, it is appropriately tucked and caught by the knitting needles on the rear needle bed. The yarn carrier 5b is stopped at the position where it has shifted to section B. In addition, transfer the stitch of the knitted fabric that is locked to the front needle bed near the end of section A and press the crossover yarn. Next, in Step S9, the crossover thread caught on the back needle bed of the A section is perforated. Next, in step S10, the yarn carrier 5b is moved in the direction of section C, and the cross yarn is pulled to loosen it. In step S11, the yarn carrier 5b is moved so as to return to the direction of the section A, and is repeated. The pulling in step S10 and the turning back in step S11 may be performed in the same manner as in steps S4 and S5 in FIG. In the next step S12, the knitting yarn supplied from the yarn carrier 5b is tucked to the last knitting needle 9 in the A section, and then the B section is knitted. In the next step S13, the stitches transferred in order to hold the crossover thread in section A are transferred from the back needle bed to the front needle bed and returned. Next, in step S14, section A is knitted with the knitting yarn supplied from the yarn carrier 5a.

FIG. 4 shows a schematic procedure for knitting the Y range following the transition yarn processing in the yarn holders shown in FIGS. 2 and 3. In step S15, the knitted fabric 10 of one course including the A section, the B section, and the C section is knitted while the carriage 3 moves to the left. First, among the two-system cam mechanisms provided in the carriage 3, the knitted fabric of the C section is performed with the yarn carrier 5c in the leading side (L), that is, the system in which the carriage 3 is on the left side. In the system on the trailing side (T), the yarn carrier 5b is also accompanied by the standby position force, tucked to the last knitting needle 9 in the C section, and then the knitted fabric in the B section is knitted. The preceding system stops entrainment of the yarn carrier 5c when the formation in section C is completed. Yarn carrier 5c waits where the entrainment is stopped. When the leading system reaches the standby position of the yarn carrier 5a, the yarn carrier 5a starts entrainment and is tucked to the last knitting needle of the B section, and then the knitted fabric of the A section is knitted. The trailing system stops entrainment of yarn carrier 5b when section B ends. Yarn carrier 5b stands by where the entrainment is stopped.

In step S16, carriage 3 reverses and moves right, while sections A, B, and C Knit 10 knitted fabric of 1 course including the space. First, of the two-system force mechanism provided in the carriage 3, the knitted fabric of the section A is carried out with the yarn carrier 5a in the system on the leading side (L), that is, the right side in the figure. In the trailing side (T) system, the yarn carrier 5b is taken from the standby position, tucked to the last knitting needle 9 in the A section, and then the knitted fabric in the B section is knitted. The preceding system stops entrainment of the yarn carrier 5a when knitting in section A is completed. The yarn carrier 5a waits at the position where the entrainment is stopped. When the preceding system reaches the standby position of the yarn carrier 5c, it starts to bring the yarn carrier 5c, connects it with the last knitting needle of the B section, and then knits the knitted fabric of the C section. The trailing system stops entrainment of yarn carrier 5b when section B ends. The yarn carrier 5b waits at the position where the entrainment is stopped.

By repeating step S15 and step S16 as described above, the knitted fabric in the Y range is knitted for each course. Therefore, in the present embodiment, in order to use the flat knitting machine 1 having a plurality of needle beds 2 and to knit the knitted fabric 10 including the section where the crossover yarn is generated, the capturing process, the pressing process, and the stitching process are performed. A process and a slack removal process are performed as a series of processes. In the catching process, the knitting yarn that becomes the transition yarn is captured by the knitting needle on the non-knitting side that is not involved in the knitting of the knitted fabric 10 in the section where the transition yarn is generated. It can be done so that it does not occur. In the above description, the knitted fabric 10 is knitted on the front needle bed and the cross yarn is captured using the knitting needles on the rear needle bed. However, when the knitted fabric is knitted on the rear needle bed, the front needle bed is used. The crossover yarn can be captured using the knitting needle. In the pressering process, the stitches of the knitted fabric that are locked to the knitting needles on the knitting side involved in the knitting of the knitted fabric are captured by the knitting needles on the non-knitting side needle bed near the end of the section. The position of the knitting yarn that extends to the yarn carrier that feeds the knitting yarn to the knitting needle that performs knitting of the knitted fabric that uses the transition yarn is determined by the knitting needle knitting. It is possible to prevent going out of the movement area in motion and perform stable knitting. In the stitching process, since the knitting needle force is released from the knitting needles captured by the knitting needles on the non-knitting side needle bed, the transition yarn processing is not completed as in the case of holding the transition yarn for a long time. There is no need to organize other courses. If the crossover yarn is held during knitting of another course, the knitting needle that holds the crossover yarn cannot be used in the knitting of another course, and the selection of the knitting needle to be used is restricted. In the loosening process, Since the loosening of the knitting yarn is removed, it is possible to prevent the crossover yarn from floating even if the crossover presser foot in the presser process is released. In this series of processes, the problem of remaining in the state of floating in the tooth gap is eliminated during the period when the crossover yarn is not knitted, so that the knitting is stable and the labor for the subsequent processing steps is reduced. Can do.

In the presser step, the stitches locked by the knitting needles on the knitting side needle bed are transferred to the knitting needles on the non-knitting side needle bed. The process can be realized easily.

In the presser process, the stitches locked by the knitting needles on the knitting side of the knitting side are described in Japanese Patent Publication No. 6-84583, page 4, left column, line 38 to page 5, right column. Disclose in line 27! / By such an increase knitting method, it is possible to hold the stitches on the non-knitting side while keeping the stitches on the knitting side needle bed and increasing the stitches, and press the transition yarns. This knitting method can be realized by a flat knitting machine using a compound needle capable of independently driving the needle body and the slider. The stitches used to hold the cross yarn by such a split increase and the above-mentioned transfer are returned to the state before use after loosening. Subsequent knitting to the knitted fabric locked on the knitting needle bed is performed on the returned stitch, so there is no problem even if it is temporarily used to hold the crossover yarn. .

Also, in the slack eliminating process, the yarn carrier that supplies the knitting yarn that becomes the transition yarn to the knitting needle is moved in the movement direction when generating the transition yarn in the interval and in the direction opposite to the movement direction. Pulling the transition yarn to remove slackness, or letting the slackness take place by a spring mechanism that applies tension to the knitting yarn.

Further, if a yarn feeding device capable of controlling the supply and drawing of the knitting yarn as disclosed in, for example, Japanese Patent Publication No. 2541574 is provided in the knitting yarn supply path, Since it is performed by using the pulling-in of the yarn feeding device, it is possible to remove the looseness of the transition yarn from the yarn feeding device side.

In addition, when the knitted fabric that follows the section is knitted on the knitting side needle bed using the transition yarn as a knitting yarn following the section in which the transition yarn is generated, the subsequent knitted fabric is provided after the loosening step. The knitting of at least the first part may be performed. This is because the knitting yarn, which was a transition yarn, can be hung on the knitting needle that knits the first part. Subsequent knitted fabric In the knitting of the knitted fabric following the first part, the knitted fabric is knitted on the needle bed on the knitting side in the section that becomes the transition yarn, and is knitted into the knitted fabric from the section that becomes the transition yarn. It is possible to smoothly switch the knitting yarns up to.

The present invention can be implemented in various other forms without departing from the spirit or main characteristic power thereof. Accordingly, the above-described embodiment is merely an example in all respects, and the scope of the present invention is shown in the claims, and is not limited to the text of the specification. Further, all modifications and changes belonging to the scope of claims are within the scope of the present invention.

Industrial applicability

According to the present invention, in order to use a flat knitting machine having a plurality of needle beds and knit a knitted fabric including a section where crossover yarn is generated, a capturing step, a pressing step, a weaving step, and slack removal The process is performed as a series of processes. In the trapping process, the knitting yarn that becomes the transition yarn is captured by the knitting needle on the non-knitting side that is not involved in the knitting of the knitted fabric in the section where the transition yarn is generated. It can be prevented from occurring. In the pressering process, the needle bed on the non-knitting side is locked near the knitting needle on the knitting side involved in the knitting of the knitted fabric! Press the crossover thread that is captured by the knitting needle. Therefore, the position of the knitting yarn extending from the holding yarn that has been pressed to the yarn carrier that feeds the knitting yarn to the knitting needle that performs knitting of the knitted fabric that uses the jumping yarn is the movement in the knitting operation of the knitting needle. You can prevent going out of the area and perform stable knitting. In the stitching process, the transition yarn captured by the knitting needle on the non-knitting side needle bed is released from the knitting needle, so that the transition yarn processing is a series of steps as in the case of holding the transition yarn for a long period of time. If you can't complete it, you can avoid the situation. In the loosening removal process, loosening of the knitting yarn, which becomes the transition yarn, is removed, so that even if release of the transition yarn by the presser foot is released, the transition yarn can be prevented from remaining loose in the mouth. . In such a series of completed processes, the transition yarn is slackened in the section where it is not knitted, and the trouble caused by remaining in the state of floating in the mouth is eliminated, thereby stabilizing the knitting, and the trouble in the subsequent processing process is reduced. Can be reduced.

According to the present invention, in the presser step, the stitches locked by the knitting needles on the knitting side needle bed are transferred to the knitting needles on the non-knitting side needle bed, so that the flat knitting machine having a transfer function Anyway In this case, the pressing process can be easily realized.

According to the present invention, the compound needle is used as the knitting needle. In the pressering step, the stitches locked by the knitting needles on the knitting side needle bed are added to the non-knitting side knitting needles. When releasing, it is possible to return to the original state simply by releasing the stitches added to the knitting needle on the non-knitting side.

Further, according to the present invention, in the slack eliminating step, the yarn carrier that supplies the knitting yarn that becomes the transition yarn to the knitting needle is moved in the direction in which the transition yarn is generated in the section and in the direction opposite to the movement direction. Since it is moved, it is possible to remove the slack by pulling the transition yarn and removing the slack, or by a spring mechanism that applies tension to the knitting yarn.

Further, according to the present invention, a yarn supplying device capable of controlling the supply and drawing of the knitting yarn is provided in the knitting yarn supply path, and the slack eliminating process is performed by using the drawing of the yarn supplying device. It is possible to remove the looseness of the cross thread from the thread side.

Further, according to the present invention, following the section in which the transition yarn is generated, when the transition yarn is used as a knitting yarn and the knitted fabric subsequent to the section is knitted on the knitting side needle bed, following the loosening step. Then, at least the first part of the succeeding knitted fabric is knitted, and the knitting yarn that was the transition yarn can be hung on the knitting needle that knitting at least the first part. After this, even if the stitch used to hold the crossover yarn in the presser process is returned to the state before use and the crossover yarn is not pressed, the crossover yarn is loosened at the mouth so that there is no buoyancy. The knitted fabric can be stably knitted in the section where the crossover yarn has been generated. Since the stitches used for holding the crossover yarn in the presser step are returned to the state before use, the knitting of the knitted fabric performed in the section where the crossover yarn is generated can be prevented.
