  • Method and apparatus for attaching lagging material to a roller
    Patent number: 5205893
    Abstract: A method and apparatus for attaching a cover (C) to a roller (R) or other device to be covered. A tube (15), cylindrical section, or other shape of cover material is inserted in a fixture (3) and each end of the tube is sealed to the fixture. A wall (21) of the fixture and a wall (23) of the tube form a chamber (19) which is evacuated so the tube expands against the wall of the fixture. A roller or other device to be covered is inserted into the fixture. The vacuum is then removed. The tube wall falls away from the side of the fixture and collapses around the outer surface of the roller.
