Abstract
An open-end spinning apparatus (1) has a spinning rotor (4) rotating in a vacuum-applied rotor housing (2) closed by a conduit plate (37) with a sliver opening device (51) delivering individualized spinning fibers into the rotor housing through a fiber guide conduit device (14) connecting the sliver opening device (51) to the conduit plate (37). The fiber guide conduit device (14) is replaceably supported in a connection bore (31) of the sliver opening housing (17). The fiber guide conduit device (14) is a cast part comprising a fiber guide conduit body (43) with a position fixing device (34) to assure a given mounting position with respect to the opening housing, a cylindrical foot having a groove (36) receiving an O-ring (35) for sealing with respect to the opening housing, and a contact shoulder (41) to support a hose nozzle (38) for sealing with respect to the conduit plate.
