ABSTRACT:
An open-end spinning unit having a one-piece fiber guide conduit inserted between the opening roller housing and the rotor housing is drawn from a steel tube and embodied as an interchangeable component. The fiber guide conduit can be releasably mounted at one end in the opening roller housing in a seating recess and at the other end in the rotor housing in a bore of a sealing plate that is attached to the rotor housing. The sealing plate maintains a low pressure condition created by a vacuum line attached to the rotor housing. This low pressure condition induces the pneumatic conveyance of opened fibers from the opening roller to the rotor through the fiber guide conduit. Sealing components, such as an O-ring in the opening roller housing and a sealing nozzle at the rotor housing assure that a sealed connection of the fiber guide conduit both with the opening roller housing and with the sealing plate is maintained for pneumatic conveyance.
