Embodiment Construction

[0024] The weft insertion nozzle 1 of the present invention is suitable for a fluid jet loom. 1 and 2 show the peripheral portion of a weft insertion nozzle (main nozzle) of an air jet loom in a fluid jet loom to which the present invention is applied.

[0025] The weft insertion nozzle 1 includes as main components: a nozzle main body 2 having an insertion hole 4, a yarn guide 3 inserted into the insertion hole 4, and a nozzle member 12 for accelerating air as a compressed fluid, and a weft yarn 9 and an air jet. Conduit 13 of the confluent hollow. Here, the insertion hole 4 forms a so-called through hole formed by coaxially connecting the first insertion hole 33 in which the nozzle member 12 is inserted and the second insertion hole 34 in which the conduit 13 is attached. The inner periphery near the opening is provided with an internal thread portion 31 for mounting the yarn guide 3 .

[0026] In addition, the material of each member is, for example, a metal material, but...

Abstract

The invention provides a weft insertion nozzle used in a liquid jet loom, which has simple structure, and which is capable of preventing weft yarn falling off from the nozzle when being cut off, without destroying stability of weft or quality of weft yarn; in the weft nozzle (1) in the liquid jet loom, a front end (1) at the side of downstream of the thread-carrier (3) is provided with a side part becoming narrow along advance of a downstream side terminal of flow direction of compacted fluid to the front end side and a protruding part (11) connected to the top of the front end, with a space of 6 to 30 numbers, being configured in circumference direction; the length a of the circumference direction of the top of the protruding pat (11) is less than the thickness t1 of the front end of thethread-carrier.

Description

technical field [0001] The present invention relates to preventing the weft yarn from bouncing back to the direction opposite to the weft insertion direction and falling off the weft yarn from the weft injection nozzle due to the rebound when the weft yarn is cut off in the weft injection nozzle used in a fluid jet loom (so-called nozzle fall off) technology. Background technique [0002] Patent Documents 1 and 2 disclose a method for preventing a nozzle of a weft insertion nozzle of a fluid jet loom from falling off. [0003] More specifically, the technology of Patent Document 1 is to embed a plurality of linear members such as fishing lines or metal wires in the weft insertion nozzle so that they are collected in the vicinity of the injection port of the weft insertion nozzle on the downstream side of the flow direction of the compressed fluid, This prevents the return of the weft yarn when the weft yarn is cut. [0004] However, according to the technique of Patent Doc...
