ABSTRACT:
The invention relates to an apparatus for the depositing of sheets at a stacking location. The apparatus has an overhead suspension arrangement 15 which is fed with blasted air and extends some way over the stacking location 2, 3. This overhead suspension arrangement 15 has an undulating profile, extending in conveying direction, which imposes on the conveyed sheet to be deposited an undulation improving its dimensional rigidity, so that it can no longer buckle or turn on striking the stop. To reduce the conveying speed of the sheets, the stacking location is preceded by an overlapping station 9, 10, which initiates the braking operation a great distance ahead of the stacking location 2, 3 and keeps the sheet at braked speed almost until the striking of the sheet against the stop 6 without the overlapping being hindered by this.
