Abstract
A composite nip roll or nip ring that is durable and requires minimal adjustment, and which accurately provides a constant gain. In accordance with an exemplary embodiment, the nip roll or ring has a rigid shaft, a resilient polymer inner material mounted on the rigid shaft, and a metal outer covering over the resilient polymer inner material. The metal covering can be rigid or flexible. The nip roll can also include limiting rings that limit deflection of the outer covering to a maximum amount.
