ABSTRACT:
A clamp which spans a pair of endless chains grips the leading edge of a sheet to convey the same into engagement with a photoconductive drum of an electrostatic copying machine or the like. A primary feed roller is driven through one rotation to feed the top sheet from a stack into the bite of the clamp. A cam follower actuated by a cam integral with the primary feed roller moves a release member into engagement with the clamp to open the same and further disengages secondary feed rollers between which the top sheet passes from the stack to the clamp. At the completion of rotation of the cam, the cam follower disengages the clamp to grip the leading edge of the sheet and engages the secondary feed rollers to feedingly grip the sheet. The secondary drive rollers are interconnected with the chains for integral driving movement after the sheet is gripped by the clamp and secondary feed rollers.
