摘要： Apparatus for singulating paper sheets. The apparatus includes: a deck for supporting a plurality of paper sheets; a device for feeding the plurality of paper sheets along the deck; a retarding roller situated above the deck for retarding the plurality of paper sheets; and a feeding roller situated below the retarding roller for feeding the lowermost of the paper sheets past the retarding roller, which has a metal sleeve with a grit coating having a hardness on the Rockwell "C" scale of at least 60 and a grit size according to the U.S. Standard System between 10 and 320.

摘要： 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.
