REMOVING OF SHRINKAGE PREVENTER OF SHRINKABLE TUBE

摘要

PURPOSE:To remove the shrinkage preventer from the inside of a shrinkable tube easily, by inserting a cylinder having a smaller diameter than a helical shrinkage preventer into the preventer which is fitted into the tube. CONSTITUTION:The cylindrical winding tube 3 having a little smaller diameter than the inside of the helical reinforcing shrinkage preventer 2 is inserted into the preventer 2 which is fitted into the shrinkable tube 1. The end of the preventer 2 is fixed to the periphery of the winding tube 3 by the tape 4, and the tube 3 is rotated in the decreasing direction of the helix diameter to wind the preventer 2 around the tube 3 and then taken out of the tube 1. The tube 3 is divided longitudinally from the split part, removed from the preventer 2, and assembled and reused.
