DEVICE FOR DELIVERY OF PAPER SHEETS, FOR USE IN APPARATUS FOR COUNTING PAPER SHEETS

摘要

Apparatus for counting the number of paper sheets has a pair of feed-out, or delivery, auxiliary rolls rotatably mounted at the bottom of a hopper for advancing paper sheets stacked in the hopper towards a payout rolls mounted adjacent the hopper outlet. Each auxiliary delivery roll has a frictional surface forming a portion of the roll periphery and a relatively slippery surface forming the remainder of the roll periphery. The frictional surface has a recessed peripheral zone, all points of which are spaced from the center of the roll by a distance less than that by which the periphery of a slippery surface, forming the remaining portion of the roll periphery, is spaced from the center of the roll. The paper sheets stacked in the hopper are moved vertically by the auxiliary rolls and advanced towards the payout roll with a larger force of friction by being contacted over a wider area by the frictional surface.
