Abstract
The invention concerns a cleaning apparatus for the cleaning of a spin rotor of a spinning station leaning head which can be insertably presented to the spin rotor and on which cleaning head are placed at least two scraper elements. In accord with the invention, the at least two scraper elements are pneumatically extendable, wherein the position of the two scraper elements are so secured on the outer circumference of the cleaning head, that the sum of the contact forces which are exerted from the scraper element in the radial direction onto the rotor is zero, or practically zero.
