Patent ID: 8790228

Claim:
A stripper roller for use in a subassembly, the stripper roller comprising: a shaft having an axially extending length and an axis of rotation; a first core disposed around the shaft, the first core keyed to the shaft such that the first core is constrained to rotate around the shaft axis of rotation in rigid accompaniment with the shaft, the first core comprising a first core member and a second core member, the first core member comprising an axially extending shaft engagement surface, an axially extending core member mating surface configured to be disposed adjacent to a core member mating surface of the second core member, and an axially extending recess area disposed substantially opposite the shaft engagement surface of the first core member; a recess area insert having a proximal edge and a distal edge, the recess area insert proximal edge configured with an interlocking geometry disposed to slidably engage within the first core member recess area; a cap having a center hole configured to slidably engage around the shaft, the cap configured to engage the first core so that the cap holds the first core member mating surface adjacent to the second core member mating surface, the cap further configured to cover the end of the recess area, thereby containing the recess area insert within the recess area; and a stop configured to restrain the cap from sliding along the shaft.
