ABSTRACT:
The collating machine comprises a frame (10), a plurality of superposed trays (20) in the frame in order to be loaded with stacks of paper (28), each tray (20) being fitted with an individual sheet ejection device and a transfer device, and a vertical conveyor (26) adjacent to the transfer devices of the trays (20) to receive, by the intermediary of the transfer devices, sheets ejected from their trays and to move the same to a collating station. The ejection device comprises several endless perforated tapes (34) carried on two spaced bend rolls (36 and 38) and a vacuum chamber (46) surrounded by the tapes (34) and having apertures, for the passage of air, distributed in its lower wall which is adjacent to the internal surface of the lower run (34a) of the tape (34). The opposite surface of the lower run of the tape (34) is positioned opposite to the top sheet (28a) in the stack in parallelism to the latter and at a distance which is maintained essentially constant by a moving plate (22) carrying the stack (28). FIG. 2.
