The spacer assembly includes at least two axially engaged components, one of which is reversible endwise relative to the other in order to change the overall axial length of the spacer assembly to thereby shift the roll axially through an appropriate distance to make use of additional grooves on the work roll.

Abstract: A nip roll is disclosed having an inner substantially rigid cylindrical member and an outer cover member of a generally incompressible substantially resilient material positioned about the inner member with reinforcing means embedded within the outer cover member having a tensile modulus greater than the modulus of the generally incompressible resilient material. The reinforcing means are so oriented with respect to the inner member that upon positioning the roll in nipped relation with a rigid roll which is externally driven, depending upon the direction of rotation, portions of the outer cover member are displaced and recoiled at the entrance and exit to the nip to provide resulting forces on web materials passed therethrough, the forces being controllable for treating such web materials. Depending upon the direction of rotation, the web material will either be compacted or elongated. A method is disclosed for producing the inventive nip roll.
