Abstract: On a lifter table (23) a pallet (2) is first deposited in a lower position and then following lifting of this table (23) the pallet (2) is precisely aligned by suitable apparatus (40). Thereafter reams of paper are deposited on the pallet (2) by a conveyor (50) and the topmost reams in each case precisely aligned relative to the pallet (2) by the same apparatus (40) in each case such that their edge faces are located set back relative to those of the pallet (2). Thereby precisely congruent stacks are achieved in fast operation.

Abstract: A device for processing ply material comprises a stationary device base; first and second transverse slides, first and second working units, and a controller. The first and second transverse slides are simultaneously displaceable in first and second contour directions on the device base, the second contour direction opposing the first contour direction and the contour directions oriented transverse to the length direction and parallel to a layer plane.

Abstract: The semiautomatic equipment included a pair of horizontal knives disposed mutually parallel, adjustable for height, and positioned a short distance from the edge of a stack of sheets for penetrating the depth of one ream, selected previously by hand. The knives are carried slidably by a beam suspended over the stack of sheets between the rails of a frame and are therefore capable of relative movement parallel with the width of the stack. The knives are movably attached to the beam by way of a carriage having guides which provide a degree of movement parallel with the length of the stack, such that an operator can bring about the initial insertion by hand before applying an actuator to lock the knives to the carriage when fully penetrated within the stack of sheets. The entire assembly of beam, carriage and knives is traversed along the frame by further actuators that are triggered to operate by a sensor mounted to the knives, and thus causing the separated ream to be moved forward to a wrapping station.
