ABSTRACT:
Method and apparatus are disclosed for feeding a continuous series of sheets step-wise to a treating machine wherein the rearward and forward edges of successive sheets are overlapped to provide a continuous supply to the treating machine. Each sheet is fed in a simultaneous step-wise manner by a feed member engaging the rear edge of each sheet. The improvement comprises the delivering of each sheet onto the last sheet on the sheet feeder such that the forward edge of the delivered sheet overlaps the rear edge of the last sheet by an amount at least as great as the prescribed overlap so that the feed member adapted to engage the rear edge of the delivered sheet will in the next feed step engage the rear edge of the delivered sheet and bring it into proper overlap position with the adjacent forward sheet which has been moved its prescribed step at the same time. In one of the embodiments the feed step is slightly greater than that desired and means are provided to retract the sheet so that its rear edge abuts a stop to assure exact positioning of the sheet with respect to the treating machine.
