Abstract
A stream of successive sheets of paper, foil or the like is converted into a series of piles at a stacking station where successive sheets are caused to descend onto a pallet which is adjacent a monitoring device serving to transmit signals denoting the levels of successive uppermost sheets of a growing pile. Such signals are processed by a unit which controls one or more valves in a pneumatic elevator for the discharge end of the endless flexible conveyor which supplies successive sheets to the stacking station. The elevator ensures that the distance between the discharge end of the conveyor and the uppermost sheets of the growing pile remains within a preselected range. This contributes to the accuracy of stacking of sheets on their pallet.
