Abstract
The present invention relates to a device for the conveying of fibers from an opener roller (31) installed in a fixed opener roller housing (30) to the collection surface (43) of a spinning rotor (4) of an open-end spinning device (1). It is provided with a rotor lid mounted on a swivel pin which receives a fiber feeding channel (6). The fiber feeding channel (6) can be brought into contact with a first contact surface (62) surrounding its inlet opening (60) against a second contact surface (35) located on the opener roller housing. It extends until directly in front of the collection surface of the spinning rotor (4). A lid extension extends through an opening in the spinning rotor (4) into the spinning rotor. In the lid extension the fiber feeding channel (6) lets out into the spinning rotor (4). The contact surfaces are essentially tangential to the circumferential surface of the opener roller and parallel to the opening of the spinning rotor or are inclined towards the opening of the spinning rotor.
