ABSTRACT:
The present invention relates to a pneumatic twisting spinning apparatus comprising a drafting device for forming a fleece, a deflection roller, a pneumatic twisting nozzle for injecting air into a twisting tube to form a swirling air stream, so that the fleece can be twisted into a yarn, a take-up roller for withdrawing the yarn, and a winding roller. The deflection roller is disposed adjacent to the front roller, for varying the direction of fleece travel and supplying the fleece along an outer peripheral wall of said front roller, and separating ends of peripheral fibers from the fleece as free fibers, which will be twisted by the pneumatic twisting nozzle so as to be wound around central main fibers, thereby forming a bundled yarn.
