ABSTRACT:
A mobile service device is provided for servicing spinning assemblies of an open-end spinning machine. The servicing device carries cleaning apparatus including a cleaning brush, a drive motor for rotatably driving the cleaning brush around its support shaft, and a selectively movable lever mechanism for moving the brush into and out of a penetrating position in a spinning rotor. Preferred embodiments of the invention include cleaning brushes having a diameter smaller than the open side of a spinning rotor to be cleaned, with the cleaning brush and its support shaft being carried by a crank mechanism for moving the shaft and brush in a circular motion so as to assure engagement of the brush with the yarn collecting groove in the spinning rotor being cleaned.
