ABSTRACT:
The invention relates to a device for supplying a shingled or overlapping sheet stream from a stack of sheets of a sheet feeder to a feed table of a sheet-processing machine with a belt table. The belt table is provided with at least one revolvingly driven suction belt, which is in operative connection with at least two suction boxes that can be acted upon by negative pressure. The invention can include a device for taking hold of the sheets. The invention also relates to altering a device so that, independently of the material to be processed, a last sheet of a sheet stream can be easily aligned. This objective is accomplished as follows: after the last sheet is detected and its front edge has been placed against the front guide stops, the operation of the suction belt is stopped.
