Adjustable upstream and downstream squaring devices are operative to square and center the stack in the cutting plane and a vertically reciprocable ram operates to move the stack and the supporting table downwardly past the blade against a table biasing force to slit the stack into two half-size stacks. The squaring device is operable to re-square the slit half-size stacks prior to conveyance out of the slitting station. The slitting run of the continuous blade operates in a rigid blade holder which is adjustable to compensate for blade wear and to maintain the cutting edge of the blade in a fixed plane.

Abstract: Apparatus for cutting stacks of sheets has a first cutting machine which subdivides large piles of overlapping sheets into elongated strip-shaped stacks. The stacks are accumulated on a platform which is moved into a second cutting machine wherein a selected number of stacks is pushed by a feeding device across the cutting plane of a guillotine type knife before the knife descends to separate smaller stacks which come to rest on a plate or enter a gap formed in response to retraction of the plate so that the severed portions of the stacks can be advanced to a processing machine. The stacks which are about to be severed are pushed by a biasing device against a stop which extends at right angles to the cutting plane in the second machine, and each such stack is further pushed by an aligning device so that it abuts the feeding device. This ensures that the stacks are properly oriented prior to severing by the knife in the second machine.
