Pneumatic spring roller bellows manufacturing method, involves providing roller bellows blank to be brought into vulcanization mold, where length of roller bellows blank exceeds double roller bellows length of roller bellows

摘要

The method involves providing a roller bellows blank (1) to be brought into a vulcanization mold (2) that has upper and lower mold halves (3, 4) coaxially arranged and placed relative to each other. The blank is fastened with ends (5, 6) at an upper end of the upper mold half and a lower end of the lower mold half. The blank is taken out from the vulcanization mold and is separated into two roller bellows of equal length by centric cutting. The roller bellows blank brought into the vulcanization mold exhibits a length, which exceeds the double roller bellows length of the roller bellows.
