Arc-shaped pressing bar device for selvedge suction device temples

Abstract

The invention discloses an arc-shaped pressing bar device for selvedge suction device temples. The arc-shaped pressing bar device for the selvedge suction device temples is characterized in that the temples are fixedly mounted in opening grooves in the upper end of a left temple base and the upper end of a right temple base of a selvedge suction device of a shuttleless loom through second screws. Holes are formed in tail handles of arc-shaped pressing bars, the thickness of the tail end of each arc-shaped pressing bar is larger than the thickness of the front end of the arc-shaped pressing bar, and one end of each arc-shaped pressing bar is connected with the corresponding tail handle into a whole so that one corresponding arc-shaped pressing bar can be formed. First screws are inserted in the holes of the tail handles, and the arc-shaped pressing bars are fixedly mounted on the bottom face of the left temple and the bottom face of the right temple respectively, so that the arc-shaped pressing bar device for the selvedge suction device temples is formed. Under the action of elastic force of the arc-shaped pressing bars, rough selvedges which are warped upwards on the fabric and wefts can be pressed, and the wefts are attached to the rough selvedges of the fabric; after the rough selvedges of the fabric are conveyed into a scissor opening, weft residues on the rough selvedges of the fabric are cut off, and the rough selvedges of the fabric are trimmed neatly.

Description

technical field [0001] The invention relates to a component of a shuttleless loom, in particular to an arc-shaped beading device for a side support of an edge suction device. Background technique [0002] In the prior art, when the shuttleless machine forms the fabric, the package yarn fixed by the weft yarn reel is weft inserted in one direction, so the two ends of each weft yarn are free ends, and the formed selvedge is also a burr. When the fabric is led to the take-up roller, the false yarn side yarn is cut and led away from the loom. In the prior art, an edge suction device is used to solve the problem of rough edges of shuttleless fabrics. The edge suction device is composed of left and right edge suction device temples and pulleys. After the scissors cut off the excess weft ends (false yarn edge yarn) at the 5cm~7cm of the ends of the weft yarn, the pulleys on the lower side of the edge suction device will guide the cut weft ends into the waste basket. However, the ...

AI Technical Summary

Problems solved by technology

However, the existing edge suction device cannot effectively cut off the false yarn side yarn due to the scissors of the left and right side suction devices. Yarn side yarn) can not run through the scissors mouth, resulting in the effect of the edge suction device can not be effectively played out, directly affecting the work efficiency and product quality of the whole machine
