example 1

[0086] In the first untwisting pipe member 40A and the second untwisting pipe member 40B of the above-mentioned embodiment, an example formed of two cylindrical members, the first untwisting pipe 41 and the second untwisting pipe 43, has been described. However, it may be formed by three or more cylindrical members. In this way, by adopting a structure in which a plurality of cylindrical members are connected in the axial direction, it is possible to easily form untwisting tube members of various lengths, and it is possible to commonize the members.

Abstract

The invention provides a untwisted tube member and a connector device having the same. The first untwisted tube member (40A) (a second untwisted tube member (40B)) is arranged on a connector device (10) which connects the yarn ends of a pair of yarns; the first untwisted tube member uses an inner circumference surface (41,43a) of the untwisted tubes (41,43) which are axially connected to form an untwisted air flow path for loosening the twisting of the yarn end.

Description

technical field [0001] The present invention relates to an untwisting pipe member and a joint device including the same. Background technique [0002] Conventionally, a yarn winding machine such as a winder unit equipped with a yarn joining device for joining a yarn end of an upstream yarn to a yarn end of a downstream yarn is known. In the case of joining the yarn end of the upstream side yarn and the yarn end of the downstream side yarn, the two yarn ends are respectively sucked into the untwisting tube part, and the yarn end is blown with pressure air in the untwisting tube part (Pressure flow), loosen the fibers that make up the yarn end. [0003] A splicing device including such an untwisting pipe member is disclosed in, for example, Patent Document 1 (Japanese Patent Publication No. Sho 62-2202) and Patent Document 2 (Japanese Patent Laid-Open No. 2009-190853). In the piecing device of Patent Document 1, a flexible tube 62 is connected to the rear end of the untwisti...
