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.
