  • compressed air is supplied to the hollow body which, when the sleeve is applied to the body and / or when the sleeve is released, flows out of the body from openings in the lateral surface of the body. Between the outer surface and the inner surface of the sleeve creates an air cushion, which easily expands the plastic film, whereby the sleeve can be mounted with little effort on the body. After application of the sleeve, the compressed air supply is stopped, so that the inner surface of the sleeve rests on the lateral surface of the body.
