In the case of a bellows, the supporting frames must be connected to the cover in a firm, leaktight manner in order to ensure the required operating reliability and to be able to manufacture the bellows economically. According to the invention, the cover (1) is produced from a film of the same composition over its cross-section in order to ensure secure welding or bonding to the supporting frame (2). <IMAGE> |
