ABSTRACT Apparatus for accumulating stacks of superimposed layers or piles of paper sheets has a horizontal platform which receives successive layers from a feeding unit and can open up to permit the properly oriented layer thereon to descend by gravity onto an elevator which is disposed at a level below the platform and at a distance only slightly exceeding the height of a layer. The elevator is then lowered by a step, and the platform receives and discharges the next layer in the same way so that the elevator supports two layers. The accumulation of layers on the elevator is repeated as often as desired in order to accumulate a stack of desired height. The elevator is then opened and permits the fully grown stack to descend through a chute and into a container (such as a carton which is disposed therebelow and is properly centered by a suitable receptacle). The descent of the stack is braked by the column of air which is pushed by the stack in front of it through the chute and into the interior of the carton. The platform comprises two panels which are movable laterally away from each other to permit a layer to descend from the platform onto the elevator or onto the topmost layer on the elevator.
