ABSTRACT:
A housing encloses a rotor, an opening roller, and a conduit communicating between the rotor and opening roller for the feeding of fiber from the opening roller to the rotor. The housing forms a trash removal chamber below the opening roller into which trash is discharged toward the bottom of the chamber during operation of the opening roller; the area of the opening roller where the trash is discharged is the trash outlet opening. The rotation of the opening roller creates an air flow draft in the direction of rotation. This air flow draft, taken in combination with suction applied in the rotor of the open-end spinning unit, creates an air flow suction draft from the chamber through the conduit in the direction of the opening roller rotation. An air flow is provided in the trash removal chamber in and from the chamber in a direction counter to the direction of the air flow draft rotating with the opening roller in the region of the trash outlet opening. A second air flow is also provided in the chamber for flow to and with the air flow suction draft.
