Adjustment of the mutual position of the latitudinal parts of a fabric guiding device

Abstract

A fabric guiding device (1) for a face-to-face weaving machine, comprising a cutting knife (8) and an upper bridge (2) and a lower bridge (3) which are positionable at adjustable distances from one another and from the cutting knife (8) by means of drive means (4a; 4b). On the other hand, a method for displacing a lower bridge (3) and / or an upper bridge (2).

AI Technical Summary

Benefits of technology

The present invention provides a fabric guiding device for a face-to-face weaving machine that can automatically and accurately adjust both the position of the upper and lower bridges and their relation to a reference in the weaving machine, such as the cutting position. This device is simpler and more efficient than existing devices, but it allows for accurate and automatic adjustment of the upper and lower bridges. Additionally, the invention also allows for easy adjustment of the lower bridge when it is positioned in either its first or second position. By reducing the size and direction of the fabric and adjusting the yarn tension or moving the weaving frames into a more suitable position, the fabric guiding device can improve the weaving process and produce higher quality products.

Problems solved by technology

Providing adjusting spindles driven by electric motors on both the upper bridge and the lower bridge and optionally using the processor unit to reach the desired position, makes adjustment of the jaw easy and reduces the risk of errors and inaccuracies, but is a complicated and expensive solution for operations which only have to be carried out occasionally.
