Abstract
An improvement in a collating machine for stacking sheets of paper fed seriatim from a singulating feeder in the same order as the sheets appear in the singulating feeder. The collating machine includes at least one upper belt and one lower belt for frictionally engaging and transporting the sheets, and ramp structure for lifting a succeeding sheet of paper over and onto a preceding, stopped sheet to form a collation. The improvement comprises a device for stopping each of the sheets, including at least one straight, vertical member against which the leading edge of each sheet abuts while the collation is being accumulated. The ramp structure and the stopping device are the upstream and downstream ends of a stacking section in the collating machine. There is a device, adjacent the stopping device, for transporting the collation from the stacking section. The transporting device is engaged when a last sheet has been stacked to form the collation, wherein the stopping device withdraws to allow the collation to pass when the transport device is engaged.
