Description

  The present invention relates to a method for retracting a knitting yarn and a flat knitting machine when knitting a knitted fabric while supplying the knitting yarn from above.

Conventionally, in a flat knitting machine, a knitting fabric is knitted by supplying a knitting yarn while driving a knitting needle arranged in parallel with a cam mechanism mounted on a carriage that reciprocates in the longitudinal direction of the needle bed. Yes. The knitting yarn is supplied from the yarn feeder at the tip of the yarn feeder that moves along with the carriage to the knitting needle that advances into the tooth mouth. As a method of supplying the knitting yarn to the yarn feeder, it is possible to feed the upper yarn through a cushioning mechanism called a top spring provided in the upper part of the flat knitting machine in the vertical direction, or horizontally from the top spring through the side of the flat knitting machine. There are side yarns that run in the direction. The yarn feeder travels along a traveling rail provided above the tooth opening.

FIG. 7 shows a configuration of a main part of a sock knitting machine 1 as an example of a flat knitting machine for upper yarn feeding. In the sock knitting machine 1, the front needle bed 2 f and the rear needle bed 2 b face each other with the tooth opening 3 interposed therebetween, and a total of four traveling rails 4 fu, 4 fd, 4 bu, 4 bd are provided above the tooth opening 3. Each traveling rail 4fu, 4fd, 4bu, 4bd is provided with one or a plurality of yarn feeders 5fua, 5fub, 5fd, 5bu, 5bd. Knitting yarns 6fua, 6fub, 6fd, 6bu, and 6bd are passed through the yarn feeders 5fua, 5fub, 5fd, 5bu, and 5bd from above. The carriage 7 can reciprocate in the longitudinal direction of the front and back needle beds 2f, 2b. A support stand 8 is provided above the carriage 7. From the support stand 8, the entrainment pin 9 appears and disappears to the side. The protruding entraining pin 9 can selectively feed, for example, the yarn feeder 5 fab to the carriage 7 and supply yarn to a knitting needle that performs a knitting operation by the carriage 7. Although not shown, the carriage 7 on the front needle bed 2f side includes another yarn feeder 5fua provided on the upper traveling rail 4fu on the front side and a yarn feeder 5fd provided on the lower traveling rail 4fd, respectively. It also has an entrainment pin that can be selected and entrained. Although the illustration of the carriage on the rear needle bed 2b side is omitted, the carriage is provided with entraining pins that can be selected and carried by yarn feeders 5bu and 5bd provided on the upper and lower traveling rails 4bu and 4bd, respectively.

In the sock knitting machine 1, socks are knitted in a tubular shape while circulating the front and back needle beds 2f and 2b by splicing the main yarn and the splicing yarn in parallel. In the splicing, the main yarn and the splicing yarn are fed from yarn feeders 5fua and 5fd provided on the two upper and lower traveling rails 4fu and 4fd, respectively (for example, see Patent Document 1) or one traveling. This is performed by feeding main yarn and splicing yarn from yarn feeders 5fua and 5fub provided on the rail 4fu (for example, refer to Patent Document 2). When the front upper yarn feeders 5fua and 5fub are used for the main yarn and the splicing yarn as in Patent Document 2, for example, the front lower yarn feeder 5fd is used for the knitting end unfastening yarn, and the rear upper yarn feeder 5bu is used. The rubber yarn and the lower lower yarn feeder 5bd are used for colored yarn, respectively.

In the following description, when the parts are collectively referred to, the suffixes such as f, b, fua, fub, fd, bu, and bd may be omitted and only the numerals may be indicated.
The sock knitting machine 1 has upper and lower traveling rails 4 of the yarn feeder 5 that are entrained by entraining pins 9 from the carriage 7 that are disposed on the front needle bed 2f and the rear needle bed 2b. In the sock knitting machine 1, the knitting yarn 6 is fed to the yarn feeder 5 by the upper yarn feeding, so that one yarn feeder 5 on the side entrained by the same carriage 7 passes over the other yarn feeder 5. Then, there is a possibility that the knitting yarn 6 fed upward to at least one of the yarn feeders 5 may interfere with the other yarn feeder 5 or the entraining pin 9 and be caught. If one yarn feeder 5 reciprocates and the other yarn feeder 5 continues to be in a resting state, the knitting yarn 6 is repeatedly caught, causing problems such as loosening, damage and cutting of the knitting yarn 6. Occur. The yarn feeder 5 is properly used as described above while the main yarn is knitted using the main yarn and the splicing yarn while the other yarn feeder 5 is retracted to the end of the needle bed 2 and the knitting yarn 6 and This is performed to make it difficult to receive interference with the yarn feeder 5.

The sock knitting machine 1 can be knitted by inserting a rubber yarn into a spliced knitted fabric at the mouth rubber part or the like. As described above, when the rear upper yarn feeder 5bu is used for supplying the rubber yarn, the rear upper yarn feeder 5bu is also entrained together with the front upper yarn feeders 5fua and 5fub. However, the movement of the rear upper yarn feeder 5bu does not cause interference even if the front upper and lower yarn feeders 5fua, 5fub, 5fd are at rest.

Further, the interference between the yarn feeder 5 and the knitting yarn 6 does not occur in a flat knitting machine that performs side yarn feeding. In a side knitting machine with a side feed yarn, a knitting yarn is supplied from a top spring to a yarn feeder via a side tension device provided at a side end of a needle bed (for example, see Patent Document 3).

In FIG. 8, the upper and lower portions 6 fdv of the knitting yarn fed from above to the lower yarn feeder 5 fd that is resting interfere with the yarn feeder 5 fua that reciprocates on the upper traveling rail 4 fu as indicated by a two-dot chain line. In order to prevent this, an example in which the yarn guide 10rl for relay is provided on the lower side to relay the knitting yarn is shown. In the yarn feeder 5fd, the knitting yarn is received by the yarn guide 10fd. Therefore, when relayed, as shown by the solid line, the knitting yarn can be supplied as the horizontal portion 6fdh from the relay yarn guide 10rl. The yarn supply to the relay yarn guide 10rl is performed at the upper and lower portions 6fdv. However, if the position of the upper and lower portions 6fdv indicated by the solid line is outside the movement range of the left row 5fual and the right row 5fuar of the yarn feeder 5fua, interference is caused. You can avoid repetition.
Japanese Examined Patent Publication No. 61-58577 Japanese Patent Publication No.61-58576 JP 2002-227064 A

  The yarn knitting can be performed by using yarn feeders provided on different traveling rails as shown in Patent Document 1, or by using yarn feeders provided on the same traveling rail as shown in Patent Document 2. Is possible. Therefore, the yarn feeder for supplying the spliced yarn with the main yarn in common is switched between the yarn feeder provided on the same traveling rail as that for the main yarn and the yarn feeder provided on a traveling rail different from that for the main yarn. Can be considered. However, when the lower yarn feeder is stopped, the knitting yarn fed upwards interferes with the upper yarn feeder.

When the upper and lower portions 6fdv of the knitting yarn to be fed interfere with the reciprocating upper yarn feeder 5fua as shown by a two-dot chain line in FIG. 8, the yarn is fed via the relay yarn guide 10rl as shown by a solid line. If the yarn is used, hooking by the upper yarn feeder 5fua will not occur. However, when the knitted fabric is knitted by reciprocating the lower yarn feeder 5fd, the yarn feeding from the yarn guide 10rl for relay to the yarn guide 10fd of the yarn feeder 5fd is performed from the lateral direction via the horizontal portion 6fdh. Therefore, there is a problem that the fluctuation of tension becomes large.

In the side yarn knitting machine, one of the reciprocating runs of the yarn feeder approaches the yarn feeding side, and the other moves away from the yarn feeding side. Pushing / pulling of the knitting yarn is caused by such approach / separation in accordance with the traveling direction, and variation in yarn tension increases. The variation in the yarn tension causes a variation in the size of the stitch to be knitted, and the stitch becomes difficult to be uniform. In Patent Document 3, the supply of the knitting yarn is controlled in accordance with the change in the direction and the demand amount so as to suppress the variation in the yarn tension. However, adding a device for controlling the supply amount of the knitting yarn and preventing tension fluctuations complicates the configuration of the knitting machine and increases the manufacturing cost.

  FIGS. 1-6 shows the schematic structure of the sock knitting machine 11 as one Embodiment of this invention. In the following description, portions corresponding to those in FIGS. 7 and 8 are denoted by the same reference numerals, and redundant description is omitted. Further, the description of the structure of the yarn feeders 5fua and 5fd described below also applies to other yarn feeders, but the description is omitted.

FIG. 1 shows a method of retracting the knitting yarn 6 in the sock knitting machine 11 of the present embodiment, corresponding to FIG. The arrangement of each part is basically the same as in FIG. The yarn feeder 5fd provided on the lower traveling rail 4fd is paused when the yarn feeder 5fua provided on the upper traveling rail 4fu is moved, and is retracted to prevent interference. Each yarn feeder 5fua, 5fd has support bodies 12fua, 12fd which are supported by the traveling rails 4fu, 4fd and which are slidably displaced. Yarn guides 10fua and 10fd for receiving the knitting yarn fed upward are attached to the supports 12fua and 12fd, respectively. When the yarn feeder 5fd pauses, the upper and lower portions 6fdv of the knitting yarn 6 that interfere with the yarn feeder 5fua are portions that face upward from the yarn guide 10fd as indicated by a two-dot chain line.

An entrainment piece 13 as a guide member is attached to the support body 12fua of the upper yarn feeder 5fua. Further, when the lower yarn feeder 5fd is stopped at one end side of the traveling rail 4fd or in the middle, a hook member 14 as a relay member is provided on the other end side of the traveling rail 4fd. The height of the entrainment piece 13 is lower than the hook member 14. Yarn feeders 15fua and 15fd are provided at the tips of the yarn feeders 5fua and 5fd, respectively. The yarn feeders 15fua and 15fd are suspended from the support bodies 12fua and 12fd by feeder rods 16aua and 16fd, respectively. The yarn guides 10fua and 10fd relay the knitting yarn fed upward to the yarn feeders 15fua and 15fd. The knitting yarn fed from the yarn feeders 15fua, 15fd to the side of the tooth mouth 3 is connected to the stitch loop in the knitted fabric or temporarily held by a looper or the like.

At the start of pause of the yarn feeder 5fd, the upper and lower portions 6fdv of the knitting yarn are in a position where interference occurs due to the movement of the upper yarn feeder 5fua, as indicated by a two-dot chain line. When the yarn feeder 5fua moves to the left through the state indicated by the broken line, the entraining piece 13 can guide the upper and lower portions 6fdv of the knitting yarn and be locked to the hook member 14 as indicated by the solid line. . The knitting yarn between the hook member 14 and the yarn guide 10fd of the yarn feeder 5fd to be stopped becomes a horizontal portion 6fdh and does not interfere with the yarn feeder 5fua that reciprocates. When the yarn feeder 5fd is used from the resting state, as will be described later, it is possible to unlock the knitting yarn only by moving the yarn feeder 5fd to the position of the hook member 14. Can be used in

FIG. 2 shows the overall configuration of the sock knitting machine 11 from the side. Feeder rods 16fua, 5fud, 5bud, 5bd of the yarn feeders 5fua, 5fd, 5bd are fed so as to feed the knitting yarns to the knitting needles 17f, 17b that advance from the yarn feeder 15 to the tooth ports 3 facing the front and back needle beds 2f, 2b. 16fd, 16fbu, and 16bd are inclined and supported by support bodies 12fua, 12fd, 12bu, and 12bd, respectively. Each support body 12fua, 12fd, 12bu, 12bd is supported by the traveling rails 4fu, 4fd, 4bu, 4bd, respectively. The selection of whether or not the yarn feeders 5fua, 5fd; 5bu, 5bd are to be taken along with the movement of the carriages 7f, 7b provided on the front and back needle beds 2f, 2b is as follows: Entrainment pins 9fua, 9fd provided on the support stands 8f, 8b; It is performed by the appearance of 9bu and 9bd. The knitting yarn fed from above is received by the yarn guides 10 fua, 10 fd; 10 bu, 10 bd provided on the respective supports 12 fua, 12 fd; 12 bu, 12 bd and guided to the yarn feeder 15. In the arrangement shown in FIG. 2, the yarn guides 10fd and 10bd of the yarn feeders 5fd and 5bd supported by the lower traveling rails 4fd and 4bd are outside, and the knitting yarn supplied to the yarn guides 10fd and 10bd from above. Inevitably interfere with the yarn feeders 5fua and 5bu supported by the upper traveling rails 4fua and 4bu, respectively.

In particular, the front upper running rail 4fu is provided with the yarn feeder 5fu of FIG. 7 which is not shown in FIG. 2 together with the yarn feeder 5fua, and one yarn feeder 5fua is used for the main yarn and the other yarn feeder 5fub is used. When the yarn feeder 5fd provided on the front and lower traveling rails 4fd is also used for splicing, interference becomes a problem. In socks in which the main portion is knitted with spliced knitted fabric, the amount of main yarn and spliced yarn is larger than that of other knitted yarns, and the frequency of use of the yarn feeders 5fua, 5fub, and 5fd is high. For the splicing, the lower yarn feeder 5fd is suspended and the upper main yarn feeder 5fua and the additional yarn feeder 5fab are reciprocated, or the upper yarn feeder 5fu is suspended. The yarn feeder 5fua for the main yarn and the yarn feeder 5fd for the lower yarn are switched by reciprocating movement. In the configuration shown in FIG. 2, when the lower yarn feeder 5fd is suspended, the knitting yarn supplied from above to the yarn guide 10fd of the yarn feeder 5fd interferes with the upper yarn feeders 5fua and 5fub that reciprocate. End up. As shown in FIG. 1, interference can be avoided by relaying with a hook member 14.

FIG. 3 shows the configurations of the yarn feeders 5fua, 5fub, and 5fd used in the present embodiment as viewed from above. The yarn feeders 5fua, 5fub, and 5fd basically receive the knitting yarn that is fed upward to the guide holes 18fua, 18fub, and 18fd of the yarn guides 10fua, 10fub, and 10fd and guide them to the yarn feeders 15fua, 15fub, and 15fd. However, the lower yarn feeder 5fd accepts the knitting yarn relayed by the hook member 14 of FIG. The yarn feeder 5fua for the main yarn is provided with an entrainment piece 13 for guiding the knitting yarn fed upward to the guide hole 18fd of the resting yarn feeder 5fd to the hook member 14. The entrainment piece 13 is provided with an inclined guide portion 13a and a locking portion 13b at the back of the guide portion 13a.

FIG. 4 shows the knitting yarn 6fd fed upward to the guide hole 18fd of the yarn guide 10fd of the lower yarn feeder 5fd resting at one end of the front needle bed 2f, with the entraining piece 13 provided on the upper yarn feeder 5fua. A state immediately before guiding to the left is shown from above. When the yarn feeder 5fua is used for supplying the main yarn, the yarn feeder 5fu shown in FIG. 7 is also used for supplying the spun yarn and travels to the left at the same time. Omitted. When the yarn feeder 5fd pauses and the yarn feeder 5fua moves to the left, the entrainment piece 13 passes through the position of the guide hole 18fd. The entrainment piece 13 is formed with a guide portion 13a that is inclined so that the left side approaches the center side of the tooth mouth 3, and the position of the guide hole 18fd corresponds to the middle of the inclination of the guide portion 13a. Therefore, the knitting yarn 6fd fed upward to the guide hole 18fd is separated from the tooth opening 3 along the inclination of the guide portion 13a by the movement of the entrainment piece 13 relative to the guide hole 18fd to the left. To the locking portion 13b.

FIG. 5 shows a state in which the knitting yarn 6fd shown in FIG. FIG. 5A shows a state in which the yarn feeder 5fua for main yarn shown in FIG. 4 is moved until the position of the hook member 14 on the left end side of the front needle bed 2f is passed while knitting the spliced yarn. Indicates. The yarn feeder 5fu for splicing yarn moves together with the yarn feeder 5fua for the main yarn. The distance between the yarn feeders 5fua and 5fub is maintained so that a necessary distance is maintained between the yarn feeders 15fua and 15fu by splicing. When the yarn feeders 5fua and 5fub are moved to the left end for the first time by switching the splicing yarn supply to the yarn feeder 5fab, the yarn feeder 5fd rests outside the range shown in FIG. 5, such as the right end side of the front needle bed 2f. . The entrainment piece 13 provided on the yarn feeder 5fua passes through the front end of the hook member 14 by locking the upper and lower portions 6fdv of the knitting yarn fed from above to the yarn feeder 5fd to the locking portion 13b. As shown in FIG. 1, the entrainment piece 13 is provided at a position lower than the hook member 14. Therefore, if the locking portion 13 b moves to the left of the inclined portion 14 a at the tip of the hook member 14, the locking piece 13 is locked. The upper part of the upper and lower parts 6fdv of the knitting yarn can easily get over the inclined part 14a. In the guide hole 18fd of the yarn guide 10fd of the yarn feeder 5fd shown in FIG. 4 that is resting on the right side of the front needle bed 2f, following the upper and lower portions 6fdv of the knitting yarn locked by the locking portion 13b of the entrainment piece 13. Is continuous with the horizontal portion 6fdh of the knitting yarn. Since the horizontal portion 6fdh of the knitting yarn passes below the yarn feeders 5fua and 5fub, it is possible to prevent interference even if the yarn feeders 5fua and 5fu reciprocate to the left and right in the drawing.

FIG. 5B shows a state in which the yarn feeders 5fua and 5fu are moved to the right from the vicinity of the hook member 14 to continue knitting splicing. The distance between the yarn feeders 5fua and 5fub is changed so that the yarn feeder 15fua of the yarn feeder 5fua for the main yarn is located on the right side of the yarn feeder 15fub of the yarn feeder 5fu for splicing yarn. This change in the interval is performed in the same manner as in Patent Document 2. When the yarn feeder 5fua for main yarn starts to move to the right, the entrainment piece 13 moves away from the hook member 14 to the right. The upper and lower portions 6fdv of the knitting yarn locked to the locking portion 13b of the entraining piece 13 in FIG. 5A are hooked to the hook portion 14b at the height of the hook member 14, and are engaged with the hook portion 14b. Stopped. On the right side of the yarn feeder 5fua, the accompanying piece 13 is separated from the upper and lower portions 6fdv of the knitting yarn, and the knitting yarn fed to the yarn feeder 5fd is relayed by the hook portion 14b of the hook member 14. As shown in FIG. 1, the horizontal portion 6fdh of the knitting yarn from the hook portion 14b of the hook member 14 toward the right side of the front needle bed 2f is located below the support 12fua and the entrainment piece 13 of the yarn feeder 6fua to avoid interference. be able to.

FIG. 6 shows a state where the relay by the hook member 14 shown in FIG. 5 is released as viewed from above. FIG. 6 (a) shows that while the upper yarn feeder 5fua is used for the main yarn and the lower yarn feeder 5fd is used for the splicing yarn and the first splicing is performed, the yarn feeder 5fua, A state in which 5fd is moved to the left until the position of the hook member 14 is passed is shown. The lower yarn feeder 5fd travels left together with the upper yarn feeder 5fua from the rest state shown in FIG. During this time, a horizontal portion 6fdh of the knitting yarn exists between the hook portion 14b of the hook member 14 and the guide hole 18fd of the yarn guide 10fd of the yarn feeder 5fd. 6fdh is knitted into the knitted fabric and the length decreases. When the locking portion 13b of the entraining piece 13 reaches the position of the hook portion 14b of the hook member 14 on the center side of the tooth opening 3, the knitting yarn 6fd locked by the hook portion 14b is moved to the locking portion 13b of the entraining piece 13. It will also start. As shown in the drawing, when the locking portion 13b of the entraining piece 13 moves to the left of the hook portion 14b of the hook member 14, the knitting yarn 6fd locked to the hook portion 14b is moved to the locking portion of the entraining piece 13. Move to 13b.

FIG. 6B shows a state in which the yarn feeders 5fua and 5fd are moved rightward from the vicinity of the hook member 14 to continue knitting splicing. The distance between the yarn feeders 5fua and 5fd is changed so that the yarn feeder 15fua of the yarn feeder 5fua for the main yarn is located to the right of the yarn feeder 15fd of the yarn feeder 5fd for splicing yarn. This change in the interval is performed in the same manner as in Patent Document 1. As the yarn feeder 15fua of the yarn feeder 5fua for the main yarn precedes to the right of the yarn feeder 15fd of the yarn feeder 5fd for the splicing yarn, the engaging portion 13b of the entrainment piece 13 is also connected to the lower yarn feeder 5fd. It moves away from the position of the guide hole 18fd provided in the yarn guide 10fd to the right. The position of the yarn guide 10fd in which the guide hole 18fd is provided is lower than the entrainment piece 13, as shown in FIG. Further, as shown in FIG. 6 (b), the position of the guide hole 18fd is closer to the center side of the tooth opening 3 than the position of the locking portion 13b of the entrainment piece 13, so the knitting yarn 6fd The portion that has been locked by the locking portion 13b moves away from the guide portion 13a and directly upwards from the guide hole 18fd while shifting to the center side of the tooth opening 3 along the inclination of the guide portion 13a. The relay at the member 14 can be released. Thereafter, splicing is continuously performed in which the main yarn is fed by the upper yarn feeder 5fua and the splicing yarn is fed by the lower yarn feeder 5fd. During this time, the upper yarn feeder 5fab rests on the right side of the front needle bed 2f. However, in the positional relationship of the present embodiment, even when the yarn feeder 5fu is stopped, there is no problem of interference with the yarn feeders 5fua and 5fd in which the knitting yarn fed upward is moved.

The start of relaying at the hook member 14 and the release of relaying are as follows: entrainment of the upper and lower parts 6fdv of the knitting yarn in the entraining piece 13 as shown in FIG. 5 and guide hole 17fd of the yarn guide 10fd as shown in FIG. However, it is possible to provide a latch for opening and closing the hook portion 14b. If a latch that opens when the entrainment piece 13 or the yarn guide 10fd arrives is provided, the latch is opened when the entrainment piece 13 arrives at the time of relay, and the latching of the upper and lower parts 6fdv of the knitting yarn is started, and is latched when the entrainment piece 13 leaves. And the upper and lower portions 6fdv of the knitting yarn can be reliably locked at the hook portion 14b. To release the relay, if the yarn guide 10fd is brought along and arrives, the latch is opened, and the upper and lower portions 6fdv of the locked knitting yarn do not pass through the hook portion 14b and enter the guide hole 18fd of the yarn guide 10fd from above. This can be done directly.

In the above description, it is assumed that when the sock knitting machine 11 performs splicing, the splicing is switched. As the spliced yarn, twisted yarn made of elastic fiber such as polyurethane or wooly nylon obtained by shrinking nylon fiber is used to impart stretchability to the knitted fabric. Therefore, if the splicing yarn can be switched, portions having different stretchability can be formed on the knitted fabric. Such switching of the spliced yarn can be used not only for socks but also for various knitted fabrics knitted with gloves or flat knitting machines.

In the sock knitting machine 11, in order to knit the heel portion three-dimensionally, a picker as disclosed as a knitting needle increasing / decreasing device in Japanese Patent No. 2777862 is mounted on the carriage 7, and the number of knitting needles used for knitting is knitted. It can be increased or decreased continuously at the edge. Socks that are knitted using a picker with only one carriage should be fitted to the shape of the foot on the toe side as well as the toe side so that the toe side is large with 5 fingers or a round tip. Due to the difference, the left and right cannot be used together, and it is necessary to organize the left foot and the right foot separately. If the picker is mounted on both the carriage 7f for the front needle bed 2f and the carriage 7b for the rear needle bed 2b, the same sock knitting machine 11 can knitting the left foot and the right foot. However, the knitting of the buttocks is performed separately for the front needle bed 2f and the rear needle bed 2b, and as shown in FIG. 2, the knitting needles 16f and 16b advancing into the tooth mouth 3 are differently shown in FIG. It is necessary to switch the overtaking direction of the yarn feeder 15 shown in a), (b) and FIGS. The same yarn is fed by the upper yarn feeder 5fu and the lower yarn feeder 5fd. For example, the yarn feeder 15fu passes the side closer to the center of the tooth mouth 3 than the yarn feeder 15fua, and the yarn feeder 15fd By overtaking the side farther from the center of the tooth mouth 3 than the yarn feeder 15fua, the right and left socks can be knitted by switching the picker to be used.

Compared to the side yarn, the upper yarn can be knitted with a uniform stitch by suppressing fluctuations in the tension of the knitting yarn with a simple yarn feeding mechanism. If the traveling rails 4bu and 4bd on the side of the rear needle bed 2b are also retracted by relaying the knitting yarn, restrictions on the use of the yarn feeders 5bu and 5bd can be relaxed and the variety of knitted fabrics to be knitted can be increased. it can. Even when the traveling rails 4 are not vertically arranged, when a plurality of yarn feeders 5 are selectively carried from the support stand 8 on one side, interference with the knitting yarn supplied upward is inevitable. Interference can be avoided by applying the present invention and performing evacuation at rest.

It is the partial front view which simplifies and shows the retraction | saving method of the knitting yarn 6 in the sock knitting machine 11 as one Embodiment of this invention. It is side surface sectional drawing which shows the whole structure of the sock knitting machine 11 shown in FIG. It is a top view of the yarn feeders 5fua, 5fub, 5fd used for the sock knitting machine 11 of FIG. 1 is a partial plane showing a state immediately before guiding the knitting yarn 6fd fed upward to the yarn feeder 5fd to be paused to the left by the entrainment piece 13 provided on the upper yarn feeder 5fua in the sock knitting machine 11 of FIG. FIG. FIG. 5 is a partial plan view showing a state in which the knitting yarn 6fd shown in FIG. It is a partial top view which shows the state which cancels | releases the relay by the hook member 14 shown in FIG. It is the simplified perspective view which shows the schematic structure of the principal part of the conventional sock knitting machine 1. FIG. 8 is a partial front view showing an example of a configuration for supplying yarn so that the yarn feeding to the lower yarn feeder does not interfere with the upper yarn feeder in the sock knitting machine 1 of FIG. 7.
