ABSTRACT:
A belt feeding assembly for feeding paper sheets. The assembly includes: a pair of side frames; an upstream shaft and a downstream shaft mounted in the side frames; a first timing pulley and a second timing pulley each having a one-way clutch for mounting on the downstream shaft; a third timing pulley and a fourth timing pulley each having a one-way clutch for mounting on the upstream shaft; a first timing belt mounted on the first and third pulleys; a second timing belt mounted on the second and fourth pulleys; and a device for driving the first and second timing belts, whereby when the first and second timing belts are initially driven at the start of operation, the one-way clutches enable the timing belts to properly and precisely seat in the timing pulleys.
