Problems solved by technology

However, if a T-type splicer is used, as in Japanese Patent Application Publication No. 2006-52485 Figure 4 As shown, since the yarn Y1 and the yarn Y2 form a "T" shape in which the overlapped part is a vertical line, the knot part remains in a kink (ヒゲ) shape (extending up and down of the yarns Y1 and Y2 in the figure). part)
Depending on the purpose of use of the yarn, this kink may cause problems in appearance

Abstract

The present invention provides a splicer nozzle (1) characterized in that a yarn splicing hole is divided, in an axial direction, into substantially two yarn splicing chambers (3, 4) formed at positions where axes (3h, 4h) of the yarn splicing chambers (3, 4) are displaced from each other, and a yarn splicing slit (2) common to the yarn splicing chambers (3, 4) is formed over the entire area of the yarn splicing hole, and in that an injection hole (5, 6) is formed for each of the yarn splicing chambers (3, 4) so that compressed air passing through the yarn splicing slit (2) to the axis (3h), (4h) of the yarn splicing chamber (3, 4) is injected through a corresponding one of the injection holes (5, 6), and an inner wall (3a, 4a) of each of the yarn splicing chambers (3, 4) located oppositean air outlet of the corresponding one of the compressed air injection holes (5, 6) is formed to be planar.

Description

technical field [0001] The present invention relates to a splicer nozzle for splicing two yarn ends overlapping in opposite directions by jetting compressed air. Background technique [0002] Conventionally, a splicer is known as a piecing device for piecing ends of two yarns. The splicer is a device that blows compressed air to the ends of two overlapping yarns and twists the ends of the two yarns together for jointing. There are two types of the splicer called the opposite type and the T-type. [0003] The opposing splicer untwises the ends of the two yarns, overlaps them in opposite directions, and twists the ends of the two yarns together by twisting backflow generated by compressed air. See, for example, Japanese Patent Application Publication No. 2-14267. [0004] On the other hand, the T-splicer overlaps the ends of two yarns in the same direction, and then uses compressed air to untwist and entangle the ends of the yarns. See, for example, JP-A-2006-52485. [00...
