Abstract
A gathering machine wherein a chain conveyor has pushers which advance below a row of platforms receiving sheets from discrete magazines. An orbiting arm in the region of each platform carries an elastic cap which engages a freshly delivered sheet to press it against the upper side of the respective platform and to accelerate such sheet in the direction of movement of the pushers so that the speed of sheets approximates or equals the speed of pushers not later than when the pushers engage and entrain accelerated sheets. Streams of compressed air are directed against the upper sides of sheets on the platforms by nozzles receiving compressed air through a valve which is closed while the platforms receive fresh sheets. The sheets which are removed from the platforms descend onto a stationary rail to form growing stacks, and such stacks are advanced by the pushers beyond the foremost platform where the fully grown stacks are removed or subjected to further treatment.
