Method for cutting stacks of sheet material

A method for transversely and longitudinally cutting rectangular starting stacks of sheet material using a single cutting machine to produce a plurality of finished partial stacks, comprising:

• positioning a starting stack of sheet material on a rear table portion of the cutting machine;
• pushing the starting stack forward under a cutting blade portion of the cutting machine at least once by a first pushing tool disposed in the area of the rear table;
• separating the starting stack into first and second partial stacks;
• pushing the first and second partial stacks back under the cutting blade using a second pushing tool;
• aligning the first and second partial stacks on the rear table to create a rectangular full stack disposed in a first stack orientation on the cutting machine;
• rotating the rectangular full stack a predetermined amount into a second stack orientation on the cutting machine that is perpendicular to the first stack orientation;
• pushing the full stack forward under the cutting blade at least once;
• separating the full stack into a plurality of finished partial stacks, transferring the plurality of finished partial stacks onto a receiving table disposed adjacent to an associated side of the cutting machine;
• and
• aligning the plurality of finished partial stacks to create a rectangular full finished stack.
