  • Patent number: 4162556
    Abstract: A method and apparatus for removing trash and the like from an elongated collection chamber provided on an open-end spinning apparatus. The trash, after separation from the fibrous material, is deposited in the collection chamber. A conveyor belt running through the collection chamber removes the large, coarse trash particles therefrom. A pneumatically intermittently operated collecting device removes the finer trash particles from the collection chamber without adversely affecting the separation operation wherein the trash is initially separated from the fibrous material. In one particular embodiment, a stripper cooperates with the conveyor belt that is used for removing the coarse trash particles for successively positioning a stream of air through the collecting chamber for removing the finer trash particles therefrom. A mechanical stripper is utilized with the stream of air for removing the fine trash particles from the walls of the chamber.
