Abstract

A twisting member (31) of a splicing device includes a yarn splicing hole (34a) in which yarns to be twisted (Y, Y1, Y2) are set, groove portions (37, 37) as gas release portions (37, 37) formed in directions different from a longitudinal direction of the yarn splicing hole (34a), and air paths (34c, 34c) provided in a pair that form air injection ports (34b, 34b), respectively, in the yarn splicing hole (34a) and form whirling flows opposite to each other inside the yarn splicing hole (34a). A plurality of groove portions (37, 37) are formed, and the air injection ports (34b, 34b) formed by the air paths (34c, 34c) in the yarn splicing hole (34a) are positioned further outside than the plurality of groove portions (37, 37).

Description

technical field

[0001] The present invention mainly relates to a splicing device which applies a fluid such as compressed air to yarn ends in the untwisting direction and overlaps said yarn ends with each other and applies a fluid such as compressed air to said overlapping portions , to splice the yarn. Background technique

[0002] Such a splicing device is disclosed in Japanese Patent Application Laid-Open No. 2005-113314 (Document 1) previously submitted to the Japan Patent Office (JPO) by the applicant of the present invention. The splicing device in Document 1 has a twisting element that jets compressed air to which liquid is added to twist (splice) yarn ends. Thus, depending on the type of yarn, yarn splicing quality, appearance and yarn strength can be improved.

[0003] as document 1 Figure 10 As shown, the twisting element includes a yarn splicing hole, an air injection port and a slit-like groove, the yarn to be twisted is set in the yarn splicing hole, and the ...
