Roller assembly for a device for manufacturing a self-twist yarn and a method of manufacturing a self-twist yarn

摘要

The assembly to produce a self-acting twisted yarn, from at least two rovings, gives the yarn zones with alternating left and right twists. At least one deflection roller (5) leads one roving (3) from its path to a guide roller (6) to be combined with the other roving (2) and be twisted into a self-acting twisted yarn (1). The roller structure, with the guide roller and deflection roller and a further deflection roller (7) are mounted on a base plate (4) so that the axes of the guide and first deflection roller are parallel on one plane. The axis of the second deflection roller is at a gap from the plane.
