Problems solved by technology

Knots formed at the front end of each spun yarn can be cut and shortened, but cannot be completely eliminated
[0004] The second prior art piecing method is a method of piecing spun yarns without forming knots by a splicer device.
[0007] In the second prior art piecing method, since the two spun yarns are overlapped and entangled in directions opposite to each other, the non-overlapping parts of the two spun yarns are further spliced, and there is a possibility that the outer diameter thereof becomes smaller. , the case where the strength of the obtained spun yarn is insufficient
Therefore, limit the spun yarn that can be pieced

Embodiment Construction

[0043] Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0044] Figure 1A ~ Figure 1D It is a front view of the knitting yarn for explaining the procedure of the piecing method according to the first embodiment of the present invention. according to Figure 1A ~ Figure 1D The order of the splicing sequence. The piecing method is a method for piecing the two knitting yarns 21, 22. The piecing method is used, for example, in the case of piecing a knitting yarn of a color different from that of the knitting yarn being knitted. In addition, the piecing method is also used in the case of piecing new knitting yarns to broken knitting yarns. In this embodiment, a method of joining two knitting yarns 21 and 22 will be described.

[0045] In the piecing method of the first embodiment of the present invention, first, two knitting yarns 21, 22 ( Figure 1A). Next, the front ends 21a, 22a of the knitting yarns 21, 22...

Abstract

The invention relates to a piecing method capable of securing the strength of a spun yarn obtained by the piecing, and omitting a protrusion treatment step for a fabric knitted by the spun yarn obtained by the piecing. Tip end portions (21a, 22a) of knitting yarns (21, 22) are overlaid in the same direction, and the knitting yarn (21, 22) are intertwined into each other to form a protruding portion (23) and a plurality of branched portions (51, 52) that are branched from the protruding portion (23). Then, the protruding portion (23) is overlaid on one branched portion (51) and the protruding portion (23) is fixed to the one branched portion (51).

Description

technical field [0001] The invention relates to a piecing method and a piecing device for piecing a plurality of spun yarns. Background technique [0002] The spun yarn used for knitting of knitted fabrics may break during knitting if excessive tension is applied. In this case, the broken spun yarn is spliced ​​with a new spun yarn to start weaving again. Piecing is performed not only for repairing cut spun yarns, but also when knitting knitted fabrics with an intarsia pattern with knitting yarns which are one type of spun yarns (for example, refer to Japanese Patent Application Laid-Open No. 6-2250). [0003] In the first prior art piecing method, ends of two spun yarns are joined by a knotting device to form a knot so that the two spun yarns are joined. In this case, the portion on the front end side of each spun yarn protrudes from the knot. After forming a knot at the front end of each spun yarn, it can be cut and shortened, but it cannot be completely eliminated. ...
