Abstract

PURPOSE: To obtain a bellow type cylinder by setting a heat shrinking plastic tube in a bellow type male metal mold and heating the same.
CONSTITUTION: A tube suitable is one having a thickness of less than 2mm made of heat shrinking plastics such as polyvinyl chloride, polypropylene, bridge polyethylene or the like is set in a bellow type male metal mold 1, and heated thereby to subject the tube to heat shrinkage to mold the tube into a desired bellow type cylinder. The male metal mold 1 must have a structure removable from the molded cylinder (for instance, consisting of a combination of several parts).
