Abstract: The dust proof sleeve comprises a rubber tubular bellows part (1) with an opening at both ends for sliding onto an element fitted with the dust proof sleeve. The bellows part (1) comprises an accordion-shaped undulated wall with circumferential peaks (2) and circumferential valleys (3). The dust proof sleeve further comprises at least one reinforcement (4), which is arranged at least along a part of the circumference of the bellows part (1) and adjoins the circumferential shape of the bellows part (1). The at least one reinforcement (4) is at least partly integrated in the bellows part (1) by vulcanization. The invention further comprises a dust proof sleeve production mould and a dust proof sleeve production method.
