ABSTRACT:
A collating machine for stacking sheets of paper fed seriatim thereto from a singulating feeder comprises a deck including a stacking area and a plurality of upper, endless, elastic belts, each of the belts moving around a pair of upstream and downstream pulleys suspended above the deck. A plurality of ramp guide blocks are adjustably secured to the deck between the pairs of pulleys, wherein a lower reach of each of the belts is lower than the highest section of the ramp guide blocks. There is structure for stopping each of the sheets at a downstream end of the stacking area which is a section of the deck between the stopping structure and the ramp guide block. Feeding structure is situated upstream from the pulleys for feeding each of the sheets over the ramp guide blocks toward the stacking area until a trail edge of the sheet moves from control of the feeding structure, wherein the belts convey the sheet to the stopping structure. A pusher transport squares the collation against the stopping structure and transports the collation from the stacking area.
