ABSTRACT:
A document feed mechanism is disclosed for feeding documents from the bottom of a stack. Sheet separating rolls prevent the feeding of more than one sheet at a time through a nip formed by the separating rolls and feed rolls. Wear compensation means functions to uniformly distribute wear about the cicumference of the separation rolls. The wear compensation means additionally provides for axial shifting of the separator rolls relative to the feed rolls so that a constant gap or nip is maintained. Simplified means for adjusting the gap are also disclosed. The feed mechanism will accept documents having a relatively wide range of thicknesses without adjustment.
