Abstract
A resilient roller is described having a rigid shaft and a flexible sleeve spaced apart by a resilient member to which axial pressure is applied. The axial pressure translates through the resilient member to become outward radial pressure. The roller of the invention is sufficiently resilient across its functional surface to maintain substantial contact and a substantially uniform nip width along its line of axial tangency with a cooperating surface.
Claims13
A cylindrical member which is sufficiently resilient across its functional surface to maintain substantial line of axial tangency with a rigid cooperating surface, said roller comprising a rigid central member, a flexible sleeve, and an elastic substance positioned between the flexible sleeve and the rigid member, in which said elastic substance is axially compressed.
