DEVICE FOR THE HEAT SHRINKING OF THERMOPLASTIC SLEEVES ON GAS CYLINDERS

摘要

The device for the heat shrinking of sleeves on Gas Cylinders described herein is a piece of equipment that works by means of compressed air and steam. Basically it comprises two opposite twin units, each made up of a hemisphere (17, 8) driven by a piston (21) which pushes it against the other unit. Working simultaneously, at the point of contact the units grip and surround the cylinder, placed in the steam area, forming a chamber into which steam is injected at a given pressure, thus heat shrinking the sleeve placed in the cylinder beforehand.
