摘要: 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.
