Method and device for manufacturing a bent rubber pipe.

摘要

A guide member (3) concentric with a mandrel (2, 402) is arranged to support a straight pipe like semi-finished rubber product (4) of unvulcanized or semi-vulcanized rubber. The semi-finished rubber product (4) is fitted on the mandrel (2, 402) by pushing the product by a head portion (7) mounted on a leading end of an arm (6). After vulcanization the bent rubber pipe (1) is extracted by having one end thereof gripped by a gripping member (10). By this, it is possible to fit and extract smoothly the semi-finished rubber product (4) and the pipe (1), respectively.
