ABSTRACT:
An open-end spinning device (1) of the type having a sliver opening device (30) and a pneumatically operated debris removal device (34) is disclosed. The opening cylinder housing (11) of the sliver opening device (30) has a debris discharge opening (15) and a cover element (9) mounted for restricted pivoting movement on a pivot shaft (10). A debris collecting element (16) is affixed to the cover element at a spacing (33) beneath the debris discharge opening and is connected to a suction device (8) which is a part of the spinning machine. The clear space (33) between the debris discharge opening (15) and the debris collecting element (16) assures that an auxiliary air flow (29), which is effective in the area of the debris discharge opening (15) to control the transport of fibers for the spinning process, is not affected by a suction air flow (28) applied at the debris collecting element (16).
