ABSTRACT:
A relatively rigid horizontally extending supporting surface supports a layup of sheet material to be cut. Air is evacuated from between the sheets in the layup, and a sheet of air impervious material covers the layup to aid in compacting the layup. One of several blanking dies in a turret is adapted for vertical movement in a carriage mechanism, which is movable in at least one coordinate direction across the layup. Relative movement in the other coordinate direction is also provided for, and the turret is rotatable on a vertical axis normal to the supporting surface for orienting the die to be used. The blanking die turret is also indexable about a horizontal axis in order to locate its various dies for the blanking motion and thereby minimize waste from the layup of sheet material.
