Description

  The present invention relates to a knitting method of a multi-layer knitted fabric and a flat knitting machine and a yarn carrier used therefor, and particularly relates to preventing interference between a warp yarn and a yarn carrier.

  WO97 / 21860 discloses knitting a multi-layer knitted fabric in which a warp layer and a weft layer are joined with a knitting yarn by a flat knitting machine. In WO97 / 21860, the warp is supplied from the supply means above the weft knitting machine to the mouth of the weft knitting machine, and the weft and knitting yarn are supplied from the yarn carrier to the mouth.

  Here, the inventor paid attention to the fact that the yarn feeder at the tip of the yarn carrier interferes with the warp when the yarn carrier is moved. When the warp interferes with the yarn feeder at the tip of the yarn carrier, the warp shifts along the tooth mouth and easily comes into contact with the needles on the needle bed, resulting in difficult knitting. Even if it does not contact the needle, the position of the warp is shifted and the knitted fabric is disturbed.

Special table 2000-501792A (WO97 / 21860)

An object of the present invention is to knit a multilayer knitted fabric without interference between a warp yarn and a yarn carrier.
An additional object of the present invention is to prevent the warp from being damaged when the warp is guided by the guide member in order to prevent interference.
An additional object of the invention is also to allow the opposing yarn carriers to cross without being obstructed by the guide member.
An additional object of the present invention is to prevent warp warped by the guide member of the yarn carrier from interfering with the needle.
Another object of the present invention is to prevent warp warped by the guide member of the yarn carrier from wrapping around the back surface of another yarn carrier.

  In the knitting method of the multi-layer knitted fabric according to the present invention, the yarn for the inlay yarn moves along the tooth opening by supplying the warp by the supplying means to the tooth opening composed of the space extending from the tip of the needle bed to the opposite side of the needle bed. The inlay yarn is supplied from the yarn feeder at the tip of the carrier to the tooth mouth, the knitting yarn is supplied from the yarn feeder at the tip of the yarn carrier for the knitting yarn moving along the tooth mouth to the tooth mouth, and knitted by the needle of the needle bed. A knit is formed from the yarns to join the warp layer and the inlay yarn layer. In the present invention, at least one yarn carrier is provided with a guide member that protrudes from the yarn carrier toward the mouth side closer to the base of the yarn carrier than the yarn feeder, and warps to the side opposite to the yarn carrier when viewed from the mouth. Is guided by a guide member.

The flat knitting machine of the present invention has at least one needle bed, and uses a space extending from the needle bed tip to the opposite side of the needle bed as a mouth that forms a stitch by a needle that protrudes from the needle bed. A multi-layer knitted fabric comprising a plurality of yarn carriers that move along the line and supply knitting yarns or inlay yarns from the tip yarn feeder to the tooth mouth and supply means for supplying warp yarns to the tooth mouth is freely knitted. In the flat knitting machine according to the present invention, at least one yarn carrier is protruded from the yarn carrier toward the mouth side closer to the base of the yarn carrier than the yarn feeder, and the warp yarn passing through the mouth is viewed from the mouth. A guide member for guiding to the opposite side of the carrier is provided. The flat knitting machine of the present invention can be used for knitting that supplies only warp and knitting yarn and does not supply inlay yarn. In that case, not a multi-layer knitted fabric but a knitted fabric composed of warp and knitting yarn is obtained.

  In this invention, since the warp is bent to the opposite side of the tooth opening by the guide member of the yarn carrier, the yarn feeder at the tip of the yarn carrier does not interfere with the warp. Accordingly, knitting of the multi-layer knitted fabric is facilitated. The guide member is preferably provided on each yarn carrier, or is provided only on one yarn carrier in the left-right direction of the mouth and not on the other yarn carrier.

In the present invention, a pipe that is supported by a flat knitting machine so as to freely swing within a vertical plane and through which a warp passes is provided, and the pipe is swung in a direction to avoid the yarn carrier by the guide member. In this way, warp can be warped without being damaged.
Preferably , a member for biasing the pipe is provided so that the pipe is vertically downward. In this way, when the yarn carrier has passed, the pipe automatically returns vertically downward.

  Preferably, in the side view of the flat knitting machine, the yarn carriers are arranged on both the left and right sides of the tooth opening, and the heights of the guide members are made different between the left and right yarn carriers. In this way, since the guide member does not interfere between the yarn carriers facing each other, the yarn carriers can be moved so as to cross. Therefore, for example, the yarn carrier can be moved with the yarn carrier for supplying inlay yarn as the leading and the yarn carrier for supplying knitting yarn as the trailing, so that the knitting efficiency can be improved. If the guide members interfere with each other, one course knitting is performed with the yarn carrier for supplying inlay yarn preceding and the yarn carrier for supplying knitting yarn following, and then the yarn carrier for supplying knitting yarn precedes and inlays in the next course. The yarn carrier for supplying yarn is followed. Further, in order to perform the reverse knitting, it is necessary to move the yarn carrier for supplying the knitting yarn so as to cross the yarn carrier for supplying the inlay yarn. For this reason, if the yarn carriers for inlay yarn and knitting yarn can be crossed, it becomes easy to knit a three-dimensional knitted fabric by turning back.

  A yarn carrier for inlay yarn and a yarn carrier for knitting yarn are arranged so as to face each other on the left and right sides of the mouth, and the guide member is provided only on one of the yarn carrier for inlay yarn and the yarn carrier for knitting yarn. The supply means is configured to supply the warp yarns while being biased from the center of the tooth opening toward the yarn carrier provided with the guide member. If the warp is supplied while being biased to the left or right from the center of the mouth, the interference between the yarn carrier on the opposite side in the left-right direction and the warp can be eliminated, and there is no need to provide a guide member on the yarn carrier on the opposite side in the left-right direction. When the warp is supplied through a pipe and guide members are provided on both the left and right yarn carriers, it is difficult for the yarn carriers to cross each other. Therefore, the above configuration is particularly effective when supplying warp yarn through a pipe.

  Preferably, the guide member includes a linear portion parallel to the longitudinal direction of the tooth opening at the center, and guide portions for guiding the warp to the linear portion on the left and right sides of the linear portion. The straight portion is not necessary for the inlay yarn carrier, and the guide portion of the inlay yarn carrier may have an arc shape or the like lacking the straight portion. If there is no straight part, the warp is inclined not only in the direction perpendicular to the longitudinal direction of the tooth mouth in the horizontal plane, that is, in the longitudinal direction of the tooth mouth, but also in the direction in which the needle protrudes and retracts. When the knitting yarn is supplied from the yarn carrier, the knitting yarn is captured by the needle in the needle bed immediately after the traveling direction of the yarn carrier to form a stitch. Here, when the warp is inclined in the longitudinal direction of the tooth opening, troubles such as the needle colliding with the warp or the needle capturing the warp occur. On the other hand, when a straight portion is provided at the center of the end face of the guide member of the yarn carrier for supplying knitting yarn, the warp to be guided does not incline along the longitudinal direction of the tooth mouth. Therefore, the above trouble can be solved.

  Further preferably, the guide portion has a shape in which the guide of the warp is started from a position farther from the mouth than the yarn carrier. To be away from the mouth means that the guide portion starts from a position farther from the mouth than the yarn carrier in a plan view at the height of the guide member with respect to the straight mouth. When a pair of front and back needle beds are provided, the center of the space between the needle beds is the tooth center line, and the guide is started from a position away from the yarn carrier with respect to the tooth center line. For this purpose, it is preferable to provide a retracted portion on the left and right sides of the guide member that extends to a position farther from the tooth opening than the back surface of the yarn carrier. In this way, the warp warped by another yarn carrier does not wrap around the back surface of the yarn carrier.

  In the following, an optimum embodiment for carrying out the invention will be shown. The scope of the present invention should be construed in consideration of the possibility of modification by well-known techniques in the description of the scope of claims.

  An example is shown in FIGS. In the figure, reference numeral 2 denotes a flat knitting machine, which includes, for example, a front needle bed F and a rear needle bed R. However, only the front needle bed F may be provided, or a larger number of needle beds such as four in the front and rear and up and down directions may be provided. A warp 4 is passed in the vertical direction between the front and back needle beds F and R, an inlay yarn (weft yarn) 6 is supplied by a yarn carrier 10, and a knitting yarn 8 is supplied by a yarn carrier 12. The tooth opening 3 is a space that continues from the tip of the needle bed to the opposite side of the needle bed, and here is a space between the needle beds F and R in plan view. The tooth opening extends at right angles in the horizontal plane with respect to the direction in which the needles of the needle beds F and R extend, and is parallel to the longitudinal direction of the needle beds F and R. When referring to the center of the mouth, it refers to the center of the mouth with respect to the direction of the needle. In addition, the center line of the mouth is at the center of the space between the needle beds F and R, and is a line parallel to the longitudinal direction of the needle beds F and R. The left and right with respect to the mouth is the direction connecting the center of the mouth and the needle beds F and R. The warp 4 is made of, for example, carbon fiber, glass fiber, aramid fiber, etc., and carbon fiber that is particularly strong and difficult to bend is preferable. The inlay yarn 6 is made of glass fiber or aramid fiber, and is particularly preferably an aramid fiber that can be easily refracted. The yarn carrier 10 supplies the inlay yarn 6, but the needle beds F and R do not perform the knitting operation on the inlay yarn 6, and press the inlay yarn 6 so that it does not rise from the mouth by a presser (not shown). . The knitting yarn 8 is supplied from the yarn carrier 12 and is subjected to the knitting operation by the needles of the needle beds F and R to become a stitch (needle loop) and a transition yarn (sinker loop), and the warp yarn 4 and the inlay yarn 6 are connected to each other. .

  FIG. 2 shows a jig 14 for supplying the warp 4, and the jig 14 is fixed to the flat knitting machine 2 at the upper part of the tooth mouth 3. The jig 14 has, for example, a large number of holes 15 through which the warp 4 passes from top to bottom and is supplied to the tooth opening 3. In the embodiment, the warp yarn 4 and the inlay yarn 6 are supplied as reinforcing fibers, but the reinforcing fiber can also be supplied obliquely. In this case, for example, the needle bed F, Supply to R. Alternatively, even if the knitted fabric is moved along the longitudinal direction of the needle beds F and R by transferring between the needle beds F and R and racking the needle beds, the reinforcing fibers can be passed diagonally. The plurality of parallel warp yarns 4 form a warp layer, and the plurality of parallel inlay yarns 6 form an inlay yarn layer, and when supplying the yarn diagonally, an oblique yarn layer is added to them. The slanted yarn is arranged in two directions, for example, a direction inclined 45 ° from the horizontal direction and a direction inclined 135 °.

  FIG. 3 shows the structure of the multi-layered knitted fabric. There are a warp 4 layer, an inlay yarn 6 layer, and a stitch 16 layer in order from the top to the bottom of the drawing. There is a layer of the inlay yarn 6 at a position closer to one side from the center of the tooth opening, and the layer of the stitch 16 is on the side farther from the center of the tooth opening than the layer of the inlay yarn 6. The transition yarn 18 between the stitches 16, 16 connects the warp 4 and the inlay yarn 6 to the stitch 16, and the stitch 16 and the transition yarn 18 join the layers of the warp 4 and the inlay yarn 6. Reference numeral 17 denotes a stitch one course before, and the stitch 16 is fixed to the lower side of the inlay yarn 6 in FIG. When the warp 4 is removed from the knitted fabric having the structure shown in FIG. 3, a kind of inlay knitted fabric is obtained. In a normal inlay knitted fabric, a stitch is formed with a knitting yarn even at the position of the warp 4 in FIG.

  In order to knit the knitted fabric of FIG. 3, for example, the warp 4 is supplied from the jig 14 so as to pass through the center of the mouth, and the yarn carrier for supplying the inlay yarn 6 is moved along the tooth opening in advance. The inlay yarn 6 is supplied. Next, the yarn carrier for supplying the knitting yarn is moved along the opposite side of the inlay yarn 6 as viewed from the warp yarn 4 (upper side in FIG. 3) in parallel with the tooth opening, and the stitch 16 is formed by the needles on the needle bed. . As described above, the yarn carrier 10 for supplying the inlay yarn precedes, and the yarn carrier 12 for supplying the knitting yarn follows. During one course of the carriage, the inlay yarn 6 can be supplied, the stitch 16 can be knitted, and the warp yarn 4 and the inlay yarn 6 can be knitted. Therefore, it can be efficiently organized. Further, the yarn carrier 10 for supplying inlay yarn and the yarn carrier 12 for supplying knitting yarn are arranged on the left and right sides of the center line of the tooth mouth so as to face each other in a side view of the flat knitting machine. For example, the stitch 16 is formed by selecting a needle on the needle bed and operating the needle between the warp 4 and the warp 4 without operating the needle in front of the warp 4. In addition, when the arrangement | positioning space | interval of a needle | hook is wide, all the needle | hooks can also be operated by arrange | positioning the warp 4 between a needle | hook.

  4 and 5 show the structure of the multilayer knitted fabric. In FIG. 4, the inlay yarn 6 layer is on the front needle bed F side of the warp yarn layer 4, and the stitch 16 layer is on the front needle bed F side. The crossover yarn 18 passes through the rear side of the warp 4, thereby joining the layer of the warp 4 and the layer of the inlay yarn 6 to the layer of the stitch 16. In FIG. 4, for example, a multilayer knitted fabric can be knitted only with the needles of the front needle bed F, and the knitting structure of the stitch 16 is a flat knitting.

  In FIG. 5, a multi-layer knitted fabric is knitted using a rib knitted fabric. There is a layer of warp 4 between the front needle bed F and the rear needle bed R, and a pair of inlay yarns 6 and 7 are arranged on both sides thereof. Further, a pair of knitting yarns 8 and 9 are used as knitting yarns, and these are knitted with ribs. The stitches 16 are formed on the front needle bed F side and the rear needle bed R side by the respective knitting yarns 8 and 9, and the warp yarn 4 and the inlay yarns 6 and 7 are formed in the layer of the stitch 16 by the transition yarns 18 and 19 therebetween. Join.

  In the embodiment, the warp 4 may interfere with the yarn feeder 25 provided on the tip 24 at the tip of the yarn carriers 10 and 12 in the vicinity of the mouth 3. That is, the warp yarn 4 passing up and down the tooth mouth 3 is carried in contact with the yarn carrier 10, 12, particularly the tip 24 at the tip of the yarn carrier 10, 12 in the vicinity of the yarn feeder 25, or The passing position may shift. When the position of the warp 4 is shifted, it may collide with a needle that advances from the needle bed or be captured by the needle, and even if it does not contact the needle, the knitted fabric may be disturbed. A mechanism for preventing the warp 4 from interfering with the yarn feeder 25 at the tips of the yarn carriers 10 and 12 is shown in FIGS.

  As shown in FIGS. 6 to 8, a plate-like guide member 26 is provided on the yarn carriers 10 and 12 to guide the warp 4. As shown in FIG. 6, the needles 20 and 21 protrude from the needle beds F and R, and form stitches by the knitting yarn 8 supplied from the yarn carrier 12. Further, the yarn carriers 10 and 12 have a tip 24 at the tip (FIG. 8), and the inlay yarn 6 and the knitting yarn 8 are supplied through the yarn feeder 25 of the tip 24. The guide member 26 is fixed to the yarn carriers 10 and 12 with a plate-like mounting portion 34 by means of a bolt 36 and a nut 38, and the fixing means is arbitrary. The guide member 26 includes a protruding portion 28 protruding from the yarn carriers 10 and 12 toward the center of the tooth mouth 3, and warps the warp 4 along the end surface of the protruding portion 28 when contacting the warp 4. As a result, the yarn carriers 10 and 12 can pass without causing the warp yarn 4 to interfere with the yarn feeder 25 of the tip 24 and the like.

  As shown in FIG. 7, there is a linear portion 30 formed of a linear end parallel to the tooth opening at the center of the protruding portion 28, and a guide portion 31 that guides the warp yarn to the linear portion 30 on the left and right sides thereof. The length w of the straight portion 30 is about twice as long as the length of the section where the needle advances from the needle beds F and R by a carriage (not shown) for operating the needles 20 and 21, and is shorter. Also good. This length is the length along the tooth opening, and is determined by the product of the needle arrangement pitch and the number of needles that the carriage advances from the needle beds F and R simultaneously. Further, the left and right guide portions 31, 31 are provided with receding portions 32, 32 continuously from the projecting portion 28, and the receding portions 32 have teeth on the back side of the yarn carriers 10, 12 (the surface opposite to the mouth). It is away from the mouth. In the yarn carrier 10 for the inlay yarn 6, the straight portion 30 may not be provided.

  Returning to FIG. 6, the mounting heights of the guide member 26 are made different between the yarn carriers 10, 12 facing each other on the left and right sides of the mouth. For example, several yarn carriers 10 and 12 can be provided on the left and right sides of the row of warps 4 (the center of the mouth), and the yarn carriers on the same side as seen from the rows of warps 4 have the height of the guide member 26 increased. It may be common or different.

  As shown in FIG. 8, there is an entrainment portion 40 at the upper part (base) of the yarn carriers 10 and 12, for example, along the yarn carrier rail (not shown) by the toothed belt 41 and the driven roller 42. Move. The yarn carriers 10 and 12 may be carried by a pin or the like that protrudes and protrudes from a member that moves together with the carriage for operating the needle.

  The operation of the guide member 26 is shown. As shown in FIG. 7, when the yarn carriers 10 and 12 move, the warp 4 comes into contact with the guide portion 31 and is guided so as to warp to the opposite side of the tooth center line 39 as viewed from the yarn carrier, and the straight portion It is guided to the next guide portion 31 through 30. For this reason, as shown in FIG. 6, the contact between the tip 24 and the warp 4 can be prevented.

  When the warp 4 is guided by the guide member 26, the warp 4 is also shifted in the longitudinal direction of the tooth mouth at portions other than the straight portion 30. When the warp 4 is shifted in the longitudinal direction of the mouth, there is a risk of interference with the needles that advance from the needle beds F and R. Here, in the straight portion 30, the warp 4 does not shift in the longitudinal direction of the mouth and thus does not interfere with the needle. In general, several needles advance from the range immediately after the center of the yarn carrier 12 in the movement direction. This section is schematically shown as a semicircle in FIG. Therefore, if the length of the straight portion 30 is at least twice as long as the length of this section, there is no possibility that the warp 4 and the needle inclined in the longitudinal direction of the mouth are in contact with each other. If the tip of the needle does not advance to the vicinity of the tooth center line 39, the needle does not contact the warp 4, so the length of the straight portion 30 may be shorter. Since the needle does not advance below the inlay yarn carrier 10, the straight portion 30 may be provided only on the yarn carrier 12 for knitting yarn.

  When the warp 4 is guided by the straight portion 30, if the yarn carriers 10, 12 cross the opposing yarn carriers 12, 10, the warp 4 may be conveyed to the back of the opposing yarn carriers 12, 10. Therefore, when the left and right retreating portions 32 and 32 are provided so that the guide to the straight portion 30 of the warp 4 starts from a position farther from the center line 39 than the back surface of the yarn carriers 12 and 10, the warp 4 is It is not carried to the back surface of the carriers 12 and 10.

It is necessary to prevent the guide member 26 from colliding when the yarn carriers 10 and 12 facing each other cross. Therefore, the guide member 26 is attached to the yarn carriers 10 and 12 facing each other at different heights.

  Instead of providing the guide member 26, the inventor can also increase the width of the mouth 3 so that the warp 4 does not contact the tip 24 in the vicinity of the tip 24 attached to the tips of the yarn carriers 10 and 12. investigated. However, if this is done, a large stitch is formed, so that the stitch layer is loosened. Accordingly, the warp 4 is warped to the opposite side of the tooth opening by the guide member 26. Further, the inventor also examined rocking the jig 14 between the front needle bed F and the rear needle bed R. For example, when the inlay yarn 6 is supplied by the yarn carrier 10, the jig 14 is swung to the rear needle bed R side so as not to interfere with the warp yarn 14, and the yarn carrier 12 is supplied with the knitting yarn. In order to avoid interference with the warp yarn 4, the jig 14 was swung to the front needle bed F side. However, in this case, a mechanism for swinging the jig 14 in synchronization with the movement of the yarn carriers 10 and 12 is required, and the vicinity of the jig 14 is arranged so that the jig 14 can swing in the opposite direction. It is necessary to shift the passing time between the yarn carrier 10 and the yarn carrier 12. Therefore, the knitting efficiency is reduced.

  FIG. 9 shows a multi-layer knitted fabric knitted in a spiral shape. Here, braided yarns are used as warp yarns and inlay yarns because this is a trial knitted fabric. In FIG. 9, the braided yarn extending from the front and back of the multilayer knitted fabric is a warp yarn, and the braided yarn folded back along the lateral direction of the multilayer knitted fabric is an inlay yarn. The reason why the multi-layer knitted fabric is spiral is that the number of stitches is different between the inside and outside of the knitting width due to turn-back knitting, so the number of stitches is small inside the knitting width and many outside. For this reason, the multi-layer knitted fabric curls the side with few stitches inward and the side with many stitches outward, resulting in the form of FIG. The multi-layer knitted fabric of FIG. 9 has a spiral shape when it is long and a partial shape of the spiral when it is short.

  10 to 14 show two types of modifications. The same reference numerals as those in FIGS. 1 to 8 represent the same components, and are the same as those in the embodiment of FIGS. 10 to 13 show a first modification, 48 is a flat knitting machine, 50 is a yarn carrier for inlay yarn, 52 is a yarn carrier for knitting yarn, and 56 is a guide member. The warp 4 is supplied to the tooth opening 3 via a pipe 60, and a pipe guide 61 is provided below the jig 14. The jig 14 and the pipe guide 61 may be integrated. The structure of the pipe 60 and the pipe guide 61 is shown in FIG. The pipe 60 is provided with a tapered portion at the upper end and is swingably supported by a pipe guide 61. The means for swingably supporting may be other than the tapered portion.

  The pipe guide 61 includes, for example, a cylindrical body 62 having a rectangular tube shape and a longitudinal direction parallel to the longitudinal direction of the tooth opening 3. Round holes 67 are arranged on the upper surface of the cylindrical body 62 along the longitudinal direction of the tooth mouth 3. Long holes 66 extending in a direction perpendicular to the longitudinal direction of the tooth mouth 3 in a horizontal plane are arranged on the bottom surface of the cylindrical body 62 along the longitudinal direction of the tooth mouth 3. An elastic body 64 such as sponge-like foamed synthetic resin or rubber is disposed in the cylindrical body 62, and holes 69 are arranged in the elastic body 64 along the longitudinal direction of the tooth mouth 3. The pipe 60 passes through the pipe guide 61 vertically through the round hole 67, the hole 69, and the long hole 66, and is arranged along the longitudinal direction of the tooth mouth 3. The pipe guide 61 is fixed to a carrier rail (rail that supports the yarn carriers 50 and 52) of the flat knitting machine 48, and may be integrated with the jig 14. Instead of the elastic body 64, one end of a spring may be attached to the pipe 60, and the other end of the spring may be fixed to the cylindrical body 62, and the pipe 60 may be urged vertically downward. An important point in the pipe guide 61 is that the round holes 67 and the long holes 66 are arranged so as to overlap each other in a plan view, and the elastic body 64 is provided therebetween. Therefore, the pipe guide may be composed of two separate plates, such as a plate provided with a round hole 67 and a plate provided with a long hole 66.

  FIG. 13 shows a guide member 56 according to a modified example. Due to the long hole 66, the pipe 60 can swing only in the direction perpendicular to the longitudinal direction of the tooth opening 3 in the horizontal plane. For this reason, it is not necessary to provide the linear member 30 shown in FIGS. In other respects, the guide member 56 is similar to the guide member 26.

  As shown in FIG. 10, when not in contact with the guide member 56, the pipe 60 is vertical. As shown in FIG. 11, when the guide member 56 comes into contact with the guide member 56, the pipe 60 swings along the long hole 66, and when the guide member 56 passes through the position where it comes into contact with the pipe 60, the force from the elastic body 64 vertically Return. In the modified example, since the guide member 56 does not contact the warp 4, the warp is not damaged.

  10 to 13, the yarn carriers 50 and 52 cannot be crossed at the position where the warp is supplied. FIG. 14 shows a modified example in which this point is improved. Reference numeral 70 denotes a yarn carrier for knitting yarn, which is not provided with a guide member, and only the yarn carrier 50 for inlay yarn is provided with a guide member 56. CL is the center line of the mouth 3, and the center of the pipe 60 and the pipe guide 71 in the left-right direction is offset from the center line CL of the mouth 3 toward the yarn carrier 50 for the inlay yarn. Therefore, the yarn carrier 70 for knitting yarn does not interfere with the pipe 60 or the warp 4 that is not guided by the guide member 56, and it is not necessary to provide the guide member 56 on the yarn carrier 70 for knitting yarn. Accordingly, the guide member 56 may be provided only on the inlay yarn carrier 50, and the yarn carriers 56 and 70 can be crossed even at the position where the warp 4 is supplied. When the pipe 60 is provided, if the guide members 56 are provided on the yarn carriers 50 and 70, the yarn carriers 50 and 70 cannot cross each other at the position where the pipe 60 is provided. In the modification of FIG. 14, the direction in which the pipe 60 swings is limited to the vicinity of the yarn carrier 70. Therefore, the pipe guide 71 is provided with the elastic body 74 only near the yarn carrier 74, and the elongated hole 76 of the cylindrical body 72 is provided. It is provided in a direction extending from directly below the round hole 67 to the yarn carrier 70 side.

  In the modification of FIG. 14, the center of the pipe guide 71 in the left-right direction is biased from the center of the tooth opening 3, but the pipe 60 is not in contact with the guide member 56. The pipe guide 71 does not necessarily have to be biased from the center in the left-right direction. Further, in the modification of FIG. 14, the guide member 56 is provided in the yarn carrier 50 for inlay yarn, and the guide member 56 is not provided in the yarn carrier 70 for knitting yarn. However, the guide member 56 is provided only for the yarn carrier 70 for knitting yarn. The member 56 may be provided so that the guide member 56 may not be provided on the inlay yarn carrier 50. In the embodiment of FIGS. 1 to 8, in order to provide the guide member 26 only on one of the yarn carriers 10 and 12, the hole 15 provided on the jig 14 is moved from the center in the left-right direction of the tooth mouth 3 to the one of the above-described ones. It may be biased to the side. If the yarn carriers 56 and 70 can be crossed even at the position where the warp yarn 4 is supplied, the knitting efficiency is increased and the back knitting is facilitated, so that the knitting of a three-dimensional knitted fabric becomes easier. The same applies to the embodiments of FIGS.

In the embodiment, the following effects can be obtained.
1) There is no possibility that the warp 4 interferes with the tip 24 in the vicinity of the yarn feeder 25.
2) The guide members 26 do not interfere with each other with the yarn carriers 10 and 12 facing each other.
3) When the straight portion 30 is provided, the needles that have advanced from the needle beds F and R do not contact the warp 4.
4) When the left and right retreating portions 32, 32 are provided, the warp 4 is not carried to the back surfaces of the yarn carriers 10, 12.
In the modification of FIGS.
