ABSTRACT:
A movable cleaning device is provided for cleaning the individual rotors on spinning assemblies of an open-end spinning machine. In order to accommodate cleaning of the rotors, with the rotor shafts being out of driving contact with their operational drives, the cleaning device is equipped with braking and/or driving means for controlling the rotational speed of the spinning rotor during cleaning operations. In this manner, cleaning elements such as rotary brushes, can be held in one position, while the relative rotational movement of the spinning rotor and the brush effects cleaning of the rotor. In certain preferred embodiments, the cleaning brush itself serves to impart rotational movement to the spinning rotor, with the drive for the brush being controllable so as to assure differential velocity of the brush and spinning rotor rotation. In other preferred embodiments, separate drive mechanisms and/or brake mechanisms are carried by the cleaning device for selective engagement directly with the spinning rotor.
