Abstract

A mobile servicing device is provided for servicing spinning assemblies of an open-end spinning machine. The servicing device includes several cleaning elements carried on a drive member which is rotatably driven by a drive motor. The cleaning elements are selectively movable into and out of a penetrating position in a spinning rotor. The cleaning elements are connected to the drive member by way of spring members which accommodate radial movement of the cleaning elements during cleaning operations. In preferred embodiments, the cleaning elements are supported on leaf springs which permit movement of the cleaning elements in the radial direction in response to centrifugal forces during rotation of the drive member. Preferred embodiments also include vacuum means as well as cleaning nozzles, with the cleaning nozzles being carried by the rotatable drive member.
