That is, the respective convex portions of the sinker and the rocker base material are engaged with the respective concave portions of the rocker sheet base material and the sinker with a gap (claim 5).

Preferably, when the knitting of the pattern of one loop is completed, the sinker is moved to the advance position by the sinker control cam, and the swing sheet base material is maintained at the advance position (claim 6).

The present invention also includes a circular knitting machine provided with the control device for the jacquard fabric of any one of claims 1 to 6 (claim 7).

The present invention also includes the combination of the base material of the wobble plate and the sinker. The sinker has a first engaging portion provided at the rear end portion, and the swing piece base material has: a second engaging portion provided at the front end portion; at least one swing piece supported so as to swing freely; At least a pair of suction portions at both ends of the first engaging portion and the second engaging portion engage with each other with a gap (claim 8).

The base material of the swinging piece has: an upward concave portion provided at the front end portion; An upward convex portion provided adjacent to the concave portion; at least one swing piece supported to be swingable; and at least a pair of suction members provided at both ends of the swing piece. The downward convex portion and the upward concave portion are engaged with a gap in the sliding direction, and the downward concave portion and the upward convex portion are engaged with a gap in the sliding direction (claim 9).

The present invention also includes a method for manufacturing a jacquard fabric, which is a method for knitting a jacquard fabric using the circular knitting machine described in claim 7, which is implemented using at least two supply paths. The knitting method of the jacquard fabric is characterized by comprising a step of supplying the ground yarn by performing stitch selection, or stitch selection or tuck selection on all the cylindrical needles in the first supply path, and in the above-mentioned process. After the cylindrical needle is lowered to the position where the loop is about to be released by the cam, it is moved to the next process of the second supply path; and at this time, the sinker is pressed out toward the center of the circular knitting machine, and the bottom yarn is located on the top of the sinker. Inside the hook of the cylindrical needle, and in front of the second supply path, the sinker is retracted from the center of the circular knitting machine to the outer direction, and the bottom yarn is held at the position on the top of the sinker. The knitting method of a floral fabric further includes a step of supplying the pile yarn by causing the cylindrical needles to perform stitch selection or float selection in accordance with a desired pattern in the second supply path, and the sinkers according to the desired pattern. The desired pattern is subjected to the process of terry selection or non-terry selection (request item 10).

In addition, the present invention includes a method for knitting a jacquard fabric using at least one supply path and a method for knitting a jacquard fabric using the circular knitting machine described in claim 7. The knitting method of the jacquard fabric is characterized by including a step of catching all the cylindrical needles in the first supply path after stitch selection is performed as they descend. The process of the bottom yarn; then, the sinker for which the mesh selection has been carried out is not moved backward, and the bottom yarn is straddled on the nose of the sinker; The process in which the yarn straddles the nose of the sinker to form a larger loop; the sinker that has been selected for non-mesh is moved while being retracted, and the bottom yarn is kept straddled by the lowering of the cylindrical needle. In the state on the top of the sinker, the cylindrical needle is further lowered to the knock-off point by the loop cam, and the ground yarn straddles the top of the sinker to form a loop of normal size (claim 11).

With regard to the above method, it is preferable that in the first supply path, when the cylindrical needle is lowered from the stitch-forming position to the tuck position, the sinker throat of the sinker in the advancing position temporarily removes the needle from the latch. The detached old yarn loops are wound into the back side of the latch to maintain the looped state (claim 12).

In the above-mentioned "Knitting Tool Control Device in Circular Knitting Machine" of Japanese Patent Laid-Open No. 9-21042, an intermediate member is provided between the sinker and the base material of the swinging piece, and the intermediate member is advanced by the intermediate member ascending cam. In order to increase the moving amount of the sinker in this way, it is necessary to provide the intermediate member ascending cam. However, in the present invention, the sinker is moved to approximately the middle of the retreating position and the advancing position of the sinker before passing through the suction member for needle selection. The middle position of the sinker can be selected to maintain the position or retreat from the middle position, so that the operation can be completed with a small moving distance of the sinker before and after, thereby reducing the space in the circumferential direction and increasing the number of supply channels. , thereby increasing the yield of fabrics. In addition, the number of parts related to the intermediate member can be reduced, the length of the sinker dial in the radial direction can be shortened, and the miniaturization of the entire apparatus can be promoted.

In addition, in terms of other effects, the present invention can also prevent a needle selection error called a so-called "flower needle" (see FIG. 12 ) from occurring. "Flower needle" refers to the phenomenon in which the old yarn loop that was temporarily detached from the latch when the needle that has been selected for stitching is lowered and hangs on the latch again as it descends, and the yarn loop that should have been looped becomes a tuck . One of the usual functions of the sinker is to cause the old yarn loop to be wound into the back side of the latch to form a loop by pressing the old yarn loop from the latch when the needle is lowered by the sinker throat. In the above-mentioned "Knitting Tool Control Device in Circular Knitting Machine" of Japanese Patent Application Laid-Open No. 9-21042, the sinker cannot be arranged at this position. In order to avoid "flower needles", the needle has to be lowered after passing through the sinker selection part to wind the old loop around the back side of the latch, which also requires space and prevents an increase in the number of supply paths. In the first supply path of Example 1 and the first supply path of Example 2 of the present application, when the needle moves from the stitching position (refer to the X-X section in FIG. 1 : FIG. 11( a )) to the tucking position (refer to FIG. 1 ) The Y-Y cross section of Fig. 11(b)) The old yarn loop that was temporarily detached from the latch at the time of descending is wound into the back side of the latch by the sinker throat of the sinker at the advancing position to maintain the looped state. A mechanism that can prevent "flower needles".

In the invention of the present application, when the terry selection is performed on the sinker, the sinker moves substantially in the circumferential direction, and the phenomenon that the sinker constantly moves in the front-rear direction as in the past does not occur. Depending on the required jacquard pattern, knitting may be performed with a reduced number of supply paths used. If the sinker is terry selected in the reduced supply path, the sinker does not perform unnecessary movement, so it is avoided that the It has an adverse effect on the fabric, and also reduces sinker wear.

The first adsorbed portion 5a of the swing piece 5 is moved by the lower surface of the swing piece retraction cam 10, and the sinker 2 is moved in a state in which the position selected by the loop is maintained.

(2)-2 In the B-B section of FIG. 4, when the sinker 2 is retracted (when the loop is not selected), a signal is sent from the controller to the first suction part 13a, so that the first suction part 13a is attracted to the first suction part 13a corresponds to the first adsorbed portion 5a of the swing piece 5. The first inclined side surface portion 5c of the rocking piece 5 is engaged with the retreating side surface 10a of the rocking piece retracting cam 10, and the rocking piece 5 is retreated together with the rocking piece base material 4, and the front end portion of the rocking piece base material 4 is upwardly convex. The engagement of the portion 4g with the downward convex portion 2g of the rear end portion of the sinker 2 causes the sinker 2 to also retreat. Then, the sinker 2, the rocking piece base material 4, and the rocking piece 5 move to the C-C cross section.

(3)-1 In the C-C section of FIG. 5 , when the sinker 2 is not retracted (when the loop is selected), the same as the state of the B-B section, the first sucked portion 5 a of the swing piece 5 is retracted by the swing piece cam 10 . The lower surface of the sinker 2 moves while maintaining the position selected by the loop.

(3)-2 In the C-C section of FIG. 6, when the sinker 2 is retracted (when the loop is not selected), the first inclined side surface portion 5c of the rocking piece 5 is engaged with the retreating side surface 10a of the rocking piece retracting cam 10, The rocking piece 5 retreats together with the rocking piece base material 4 to the lowermost part 10b of the rocking piece retreating cam 10, and the upward convex portion 4g of the front end portion of the rocking piece base material 4 and the downward convex portion 4g of the rear end portion of the sinker 2 are accompanied with this. The engagement of the convex portion 2g makes the sinker 2 Backward, the pile yarn PY does not straddle the sinker nose 2b and thus does not form the pile yarn PL.

(4) In the D-D section of FIG. 7 , all the sinkers 2 are advanced to the position where the old loop of the knitting needle is disengaged by the second sinker control cam 8, and the rear end portion of the sinker 2 is accompanied by this. The engagement of the downward convex portion 2 g with the upward convex portion 4 g of the front end portion of the rocking sheet base material causes the rocking sheet base material 4 to also advance together with the sinker 2 .

Hereinafter, the 1st supply path F1 and the 2nd supply path F2 are repeated, and the knitted fabric of the terry jacquard pattern of one loop is formed by one course. When the knitting of the pattern of one loop is completed, the sinker is moved to the advance position by the sinker control cam, and the aforementioned oscillating sheet base material is maintained at the advance position.

As shown in Fig. 9, when the sinker is selected by the loop, the pile yarn PL and the ground yarn GL are formed. On the other hand, when the sinker is selected as non-terry, a two-layer loop is formed by the ground yarn GY and the pile yarn PY. It should be noted that the loop formed by the needle is represented by the needle loop NL, and the loop formed by the sinker is represented by the sinker loop SL.

[Example 2]

The jacquard knitting method according to the second embodiment of the present invention will be described based on the action diagram of the cylindrical needle and the sinker in FIG.

In the first supply path F1 in FIG. 8 , the operating line N11 of the cylindrical needle indicates the stitch selection. In addition, the solid line of the operation line of the sinker 2 represents the non-mesh selection T22n, and the broken line represents the mesh selection T22m. In the 1st supply path F1, the mesh selection or non-mesh selection of the sinker is performed according to a desired pattern.

That is, in the first supply path F1, after stitch selection is performed on all the cylindrical needles, the bottom yarn GY is caught as it descends, and the sinker 2 on which the mesh selection T22m is performed thereafter is not moved backward, and the bottom yarn GY is caught. The yarn GY straddles the sinker nose 2b. The cylindrical needle is lowered to the knock-off point by the yarn bending cam, and the ground yarn GY straddles the sinker nose 2b to form a larger loop 17b. On the other hand, the sinker 2 on which the non-mesh selection T22n has been performed moves while being retracted, and the state where the ground yarn GY straddles the sinker top 2f is maintained as the cylindrical needle descends. The triangle is further lowered to the knock-off point, and the ground yarn GY straddles the sinker top 2f to form a normal size loop 17s.

Hereinafter, the pattern of one loop is formed by one course by repeating the first supply path. When the knitting of the pattern of one loop is completed, the sinker is moved to the advance position by the sinker control cam, and the oscillating sheet base material is maintained at the advance position.

Fig. 10 shows the yarn loops 17b larger than the usual size and the yarn loops 17s of the usual size formed by the first supply path. The sinker loop SL of the portion where the mesh selection is made becomes larger, and the loop 17b larger than the normal size is formed, and the sinker loop SL of the portion where the non-mesh selection is performed does not become larger, and becomes the normal size. 17s of yarn loops.

A jacquard fabric consisting of one thread is thus formed by the combination of the larger loops 17b and the generally sized loops 17s.

It should be noted that knitting may be performed by combining the first embodiment and the second embodiment.
