ABSTRACT:
This invention relates to a device for distributing semi-rigid sheets, one by one, below or above a stop behind which said sheets are stacked. The device has no sheet-extraction system in front of the stop and no fixed surface in contact with the stack in the proximity of the stop. It comprises at least three cylinders adapted to entrain by friction the sheet with which they are in contact, the axis of the outlet cylinder being vertical with respect to the stop. Moreover, it comprises a device for synchronizing the cylinders so that, during distribution of a given sheet, on the one hand, each of the cylinders upstream of the outlet cylinder is decelerated after the sheet has left contact therewith and, on the other hand, the outlet cylinder is decelerated after the rear edge of the sheet has substantially gone beyond the vertical with respect to the stop, the cylinders upstream already being in stopped position.
