Claim Text:
1. A contact nip roll, comprising: a shaft having an axis, wherein the shaft passes through a first end plate on a first end of the shaft and a second end plate on a second end of the shaft opposite the first end thereof, and wherein each of the first and the second end plates are secured to and in direct contact with the shaft, a first compliant material, having a first Young's modulus, in annular contact with the shaft and between the first end plate and the second end plate; a plurality of stacked annular rings stacked together along surfaces normal to the axis of the shaft and arranged between the first end plate and the second end plate, wherein the annular rings have a Young's modulus greater than the Young's modulus of the first compliant material, each annular ring comprising: an inner edge at least partially in contact with the first compliant material; and an outer edge concentric with the axis; and wherein the plurality of stacked annular rings comprise a first outer annular ring in contact with the first end plate, and a second outer annular ring in contact with the second end plate, respectively, and wherein the first and second end plates maintain a longitudinal force parallel to the axis of the shaft to compress together the plurality of annular rings.
