Abstract
Servicing apparatus, such as rotor cleaning and yarn piecing apparatus, for servicing individual spinning assemblies of an open end spinning machine is provided. Operational disturbance responsive control equipment is provided for controlling the movement of the servicing apparatus to servicing positions at respective spinning assemblies where operational disturbances are detected. Step-by-step control equipment is also provided to control the servicing apparatus for sequential preventive maintenance servicing operations at the various spinning assemblies. In order to optimize preventive maintenance and disturbance response maintenance, a switch-over switch is provided for switching between the disturbance responsive control equipment and the step-by-step control equipment.
