Fluid jet type weaving machine

Abstract

The present invention provides a fluid jet type weaving machine having a planet selvedge apparatus and a catching side-warp opening device corresponding to high-speed running. The fluid jet type weaving machine having a planet selvedge apparatus and a catching side-warp opening device that are supported on one side reverse to picking of the weaving machine is provided with a driving shaft having a half speed ratio of a main shaft, a rotating shaft is driven by the driving shaft to rotate through a rotating transfer mechanism, and a swinging rod is driven by the driving shaft to swing through a sport changeover mechanism. The rotating transfer mechanism comprises a first toothed rotary part that is moveable in the direction of axial cord and is fixed on the driving shaft, and a second toothed rotary part having an identical number of teeth with the first toothed rotary part and being fixed on the rotating axle, and the rotating transfer mechanism is arranged to form that the connectionphase of the rotating shaft with the driving shaft is changeable. The sport changeover mechanism comprises a rotary part for making the swinging rod swing, the rotary part is moveable in the direction of the axial cord, is independent with the first toothed rotary part, is fixed on the driving shaft and is arranged to form that the connection phase of the rotating shaft with the driving shaft is changeable.

Description

technical field [0001] The present invention relates to a fluid jet loom having a planetary selvage device and a weft catcher warp opening device arranged on the opposite side of the weft insertion side of the loom. Background technique [0002] A fluid jet loom having planetary selvage devices on the weft insertion side and the opposite weft insertion side of the loom. Since the weft yarn becomes slack with the end of the threading, there is also a fluid jet loom which is adjacent to the planetary selvage device arranged on the opposite side of the weft insertion and has a weft catching side warp opening device, which is formed on the outside of the side warp opening. Catch weft side warp openings. [0003] In the fluid jet loom described in Patent Document 1 (Japanese Utility Model Publication No. 3-43261), the weft catching edge warp opening device has: a first shaft and a A second shaft; a first lever that is swingably supported on the first shaft; a second lever that ...

AI Technical Summary

Problems solved by technology

Therefore, the timing of the shedding movement of the side warp and the timing of the shedding movement of the weft-catching side warp deviate from the optimum timing based on the rotation angle of the main shaft of the loom, resulting in weft insertion errors, etc., and the operation of the loom will inevitably become unstable.
