ABSTRACT:
A self-adjusting resilient roller, particularly for use with a feed roller, to provide for a self-adjusting system whereby the self-adjusting roller will conform to various thicknesses of sheet material between the self-adjusting roller and the feed roller without adjusting the position of the rollers, the self-adjusting roller formed of resilient material having a central axial pasageway for a shaft, and a plurality of smaller generally circular openings surrounding the central passageway and characterized further by a generally triangular opening toward the outer periphery of the self-adjusting roller and between each smaller circular opening, so as to provide a generally uniform wall thickness of resilient material surrounding each of the circular openings in the self-adjusting roller, whereby uniform resiliency under compression is imparted to the roller.
