US Patent No: 6263654

Arrangement for a ring spinning machine for condensing a fiber strand and method of making same

---

Abstract

---

An arrangement for a ring spinning machine for condensing a drafted but untwisted fiber strand includes a drum which transports the fiber strand through a condensing zone. The drum is provided on its outer sleeve with a perforation. In order that the perforation can be particularly fine and close-meshed, the outer sleeve of the drum forms a supporting skeleton, which comprises openings, which are covered over by a thin sieve belt, preferably a woven tape. The sieve belt extends over a suction slit located in the condensing zone. The skeleton is so formed that in the area of nipping points, formed together with the drum, the skeleton is sufficiently resistant.
