摘要:
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).

The invention relates to a cleaner device of a splicer apparatus which is disposed on the splicer apparatus and in which fibrous dust can be sucked and removed efficiently. A suction portion (5) is provided in a vicinity of a splicing nozzle (4) in which yarns are exposed to a compressed air flow that is a compressed fluid flow and pieced into each other, and they are covered with a cover member (70). Covering them with the cover member (70) results in formation of a closed space (71) in which the splicing nozzle (4) and the suction portion (5) are disposed at least during piecing yarns with the splicing nozzle (4). Fibrous dust produced during piecing is prevented from being scattered in a wide space, and is kept in the closed space (71) covered by the cover member (70). The suction portion (5) sucks fibrous dust in this closed space.

The invention relates to a splicer apparatus capable of being downsized and preventing an operation failure caused by fibrous dust. A yarn (12a) selected by a yarn selecting portion (3) among yarns (12), held by a yarn holder (13) is put in a groove (7a) of a splicing nozzle (7) by a yarn guide lever (14) and pieced into a currently used yarn (12b). Then, the currently used yarn (12b) is cut by a cutter (30) and switched over to another yarn. A yarn lint produced is sucked by a suction portion (19). A base (2) has a partition wall (100). First and second motors (4, 5) which drive the yarn guide lever (14) and the cutter (30), respectively, are disposed on the partition wall (100) on an opposite side of the yarn holder (13), the yarn guide lever (14), the splicing nozzle (7), the suction portion (19) and the cutter (30).
摘要:
A yarn splicing method in which a yarn lint treatment step for fabric that is knitted with spun yarns obtained by yarn splicing can be eliminated with sufficient strength of the spun yarns maintained. Two knitting yarns (21, 22) are disposed with their end parts (21a, 22a) superposed over each other while being oriented in the same direction, and the yarns are twisted around each other to form a projecting part (23) and branched parts (51, 52) branched from the projecting part (23). The projecting part (23) is superposed over and along one branched part (51) and fixed to it.

An objective of the present invention is to provide a yarn changing device for sequentially selecting any of plural types of yarns different in color or suchlike, andperformingyarnpiecing upon each supply to a yarn feeding device in a knitting machine. The present invention is directed to a yarn changing device for selecting a yarn between plural types of yarn supply packages different in color or suchlike and a yarn feeding device in a knitting machine, and feeding the selected choice yarn to the yarn feeding device in the knitting machine after piecing the choice yarn with a knitted yarn being knitted, the yarn changing device comprising: suctioningmeans 28 for collectively suctioning and holding a plurality of yarns; and clamping means 29 for collectively clamping the yarns between the suctioning means and the yarn supply packages, the clamping means including first and second clampers 29A and 29B disposed in two places along a yarn path and activated selectively.

The invention relates to a splicing head that can improve the strength of a pieced portion. A plurality of two-ply yarns (70, 71) that are to be pieced are untwisted by injecting a compressed fluid via an untwisting-nozzle hole (32) Subsequently, an impact is imparted to the plurality of two-ply yarns (70, 71) thus untwisted by injecting a compressed fluid via a piecing-nozzle hole (33). When the plurality of two-ply yarns (70, 71) are untwisted respectively, and then an impact is imparted to the plurality of two-ply yarns (70, 71) from a compressed fluid in this manner, the plurality of two-ply yarns (70, 71) themselves are complexly intertwined into each other, and fibers projecting from the plurality of two-ply yarns (70, 71) are complexly intertwined into each other. Accordingly, the strength of a pieced portion in a yarn obtained by piecing can be improved.
