Abstract
Apparatus for repeatedly cutting stacks of overlapping sheets has a first cutting machine from which large stacks are transferred to a loading station which is adjacent a transfer station where the stacks are loaded upon successive wheel-mounted pallets for transport into the second cutting machine. A feeding unit is provided to shift selected numbers of stacks on the pallet which is located in the second machine onto a working platform beneath the guillotine type knife and the hold-down device of the second cutting machine so that the pallet supports portions of stacks which are being severed. The stacks are oriented on the pallet at the loading station, and additional changes in orientation of the stacks can be carried out on the pallet and/or on the adjacent working platform in the second cutting machine.
