Abstract
The utility model provides a false twist spinning device with a tangential belt in straight and rotation composite motions. The device comprises the round tangential belt and a tangential belt transmission mechanism, and is characterized in that the tangential belt transmission mechanism carries out rotation motions with the axis of the tangential belt as a center while enabling the tangential belt to carry out axial straight motions, and namely the tangential belt carries out false twist and silver conveying for silver by means of the straight and rotation composite motions. The straight motions of the tangential belt drive the silver to roll around the center of the silver to produce the false twist degree, the rotation motions of the tangential belt enable the silver in axial motions and in contact with the tangential belt to be conveyed to a downstream due to self-rotation of the tangential belt, and therefore quality influences brought about by sliding friction between the silver in the axial motion and the tangential belt are eliminated or reduced.
