Abstract

See full text

An improved elastomer covered feed roll assembly (32R) for use in a feed/pull roll set combination (36) in a sheet finishing machine (12) comprises a roll core (50) having a cylindrical surface (60) with multiple longitudinally spaced and circumferentially offset elongated keyways (80, 82, 84, 86) each configured as a locking slot. Multiple replaceable flexible feed cover sections (52, 54, 56) each incorporating a flexible backing (120) and an elastomeric layer or coating (122) are removably mounted on the roll core by locking components (74, 76) on opposite ends (70, 72) of each of said replaceable flexible feed cover sections, the locking components of each replaceable flexible feed cover section engaging a locking slot (80, 82, 84, 86) corresponding to the feed cover section. The keyways draw together the opposite ends (70, 72) of corresponding cover sections to form corresponding end joints (96, 98, 100).
