Abstract
A condensing zone is arranged downstream of the front roller pair of a drafting arrangement of a spinning machine, in which condensing zone a drafted roving or a sliver is condensed. The condensing zone has a suction device which has a closed hollow profile and which serves as a sliding surface for a circulating sieve belt. The sieve belt transports the drafted fiber strand to a nipping roller, which presses the fiber strand and the sieve belt against the sliding surface at a nipping point. The fiber strand travels over an essentially in transport direction extending suction slit located in the condensing zone, which suction slit extends to the nipping point.
Claims6
A fiber strand transport belt configured for transporting a fiber strand over a suction slit of a hollow member while the fiber strand is condensed utilizing suction air applied at the suction slit,
- wherein the transport belt has plural openings disposed laterally adjacent one another which in use open to the suction slit to permit flow of suction air therethrough to facilitate condensing of a fiber strand transported thereby.
