ABSTRACT:
An open-end spinning apparatus having a fiber conveying path between a fibrous material feed device and a spinning compartment. A trash separating device which includes an aperture and a dividing edge is provided for removing trash from the fibrous material as it is conveyed along the conveying path extending around an opening roller. A collection chamber is provided for receiving the trash from the trash separating device. Interposed between the trash separating device and collection chamber is an auxiliary chamber. A first aperture extends through a wall of the auxiliary chamber through which a stream of air flows for being introduced into the fiber conveying path. A second aperture is provided in an opposed wall of the auxiliary chamber through which a smaller stream of air is removed from the auxiliary chamber along with small particles of fly and trash. A controllable closing member is disposed between the auxiliary chamber and the trash collection chamber which is closed when air is used for removing the trash collected in the trash collecting chamber.
