Embodiment Construction

[0046] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The warp thread opening device 100 of the weft catching edge of the first embodiment is used as a fluid jet loom for a water jet loom or an air jet loom, and the planetary edge selvedge device installed on the side opposite to the weft insertion of the loom 110 are arranged contiguously.

[0047] figure 1 It is a front view showing the warp opening device 100 of the weft catching side seen from the center of the loom along the fabric width direction on the side opposite to the weft insertion (reverse weft entry side). In addition to the warp opening device 100 of the weft catching side, there are also Shown are the planetary edge selvedge device 110, the reed 50, the weft yarn cutting device 25 for cutting the weft yarn Y held by the warp thread C of the caught weft edge, and the false twist spindle device 26 for false twisting the warp thread C of the caught weft...

Abstract

The invention relates to a catchcord opening apparatus of loom, aims to provide a catchcord opening apparatus which doses not applies tension to the weft yarn end sharply, and reduces the possibility of texture disadvantage such as weft yarn retraction generated in fabric. The apparatus has: a first shaft and a second shaft disposed opposite wefting side; a plurality of first swing rods supported on the first shaft; and a plurality of second swing rods supported on the second shaft. each swing rod has a inserting hole for inserting warp yarn with actchselvedge, and the swing rods swing to opposite directions; the front ends of the second swing rods are arranged to move into and out from the spaces between the front ends of the first swing rods; the catchcords are arranged to perform an opening movement and intercrossed while clamping the weft yarn ends along with the swing of the first and second swing rods; thereby, in the catchcord opening apparatus of the fluid jet type loom on the catchcord holding weft yarn end, at least two of the first swing rods is inserted into the hole and reached to the cord position line at different times.

Description

technical field [0001] The present invention relates to the swing lever which is arranged on the opposite side of the weft insertion of the loom and has the insertion hole of the warp thread of the weft catching side to swing to make the warp thread of the weft catching side perform opening movement, and the warp thread of the weft catching side is held by the warp thread of the weft catching side along with the opening movement The warp opening device of the weft catching side of the fluid jet loom that applies tension to the weft yarn at the end of the weft yarn. Background technique [0002] In the fluid jet loom, since the weft yarn is loosened with the end of the threading, the fluid jet loom has a warp opening device with a weft catching edge on the opposite side of the weft insertion. The end of the weft yarn is held in a curved manner by moving along the shed, thereby suppressing the weft yarn from slack after passing and imparting tension to the weft yarn. [0003]...
