ABSTRACT:
A device for aligning wefts of textile belts comprises four arched cylinders which are positioned so that they define a regular or irregular quadrilateral. The orientations of the axes and angular positions of the cylinders are adjustable. In other words, the cylinders are tiltably and rotatably mounted. The cylinder positions are adjusted so as to ensure that the textile belt to be aligned is able to contact only that part of the circumferential surface of the cylinders which has a predominantly widening effect on the textile belt. The mechanism of orienting the four arched cylinders includes two servomotors for driving gears and transmission chains in a manner which is effective for selectively tilting and/or rotating the cylinders so as to correct textile belts having arch-like and/or skewed wefts.
