  • Method and apparatus for wrapping, crimping and heading paper rolls at a single station
    Patent number: 5642600
    Abstract: A method and apparatus for applying a wrapper to a paper roll, a turret mechanism has a crimper and an inside head holder on one side and an outside head applying platen on the opposite side, a drive for rotating the turret mechanism to place the crimper and inside head holder adjacent the paper roll end to place an inside head on the paper roll and crimp the wrapper over the inside head, and then rotating the turret mechanism to place the outside head applying platen adjacent the paper roll to place an outside head over the crimped wrapper all at a single station. The inside head holder has several retractable vacuum cups that can also apply positive air pressure to hold the inside head against the roll and during crimping. The vacuum cups are sequentially, independently retracted as a crimp approaches to clear the crimp as the paper roll is rotated.
