  • Multiple durometer pressure roller
    Patent number: 5967450
    Abstract: A multiple durometer pressure roller for winding a web of deformable material onto a core, particularly for reducing air entrainment in the wound roll. The pressure roller includes a rigid cylindrical shaft, a resilient central sleeve supported by the shaft, and two end sleeves supported at each end of the resilient sleeve. The end sleeves have a lower durometer than the resilient sleeve. In a preferred embodiment, the end sleeves and the resilient sleeve are covered by an outer cover having a higher durometer.
    Type: Grant
    Filed: February 3, 1998
    Date of Patent: October 19, 1999
    Assignee: Eastman Kodak Company
