Abstract
A mechanically operating debris removal device for an open-end spinning machine 1 comprises a guide conduit arranged below the spinning units and enclosing a debris conveyor belt. The guide conduit comprises a base and a cover, which may be pivotable or detachable relative to the base. During spinning operation, the base and the cover form an essentially closed belt guide conduit. Debris passage openings are formed in the cover with associated air and debris guide deflectors to communicate with debris exit openings in the sliver opening devices. The upper run of debris conveyor belt creates a slight suction flow in guide conduit and at the debris passage openings to prevent fine debris from settling in the area of the debris passage openings and in the area of debris exit openings of the sliver opening devices.
