ABSTRACT:
A method and apparatus for blanking wide sheet materials into a plurality of pieces of predetermined shapes are disclosed. The apparatus comprises a blanking die press and first and second carriages movable in a predetermined, numerically controlled and programmable sequence along Y and X axes, respectively, relative to the blanking die press. The blanking die includes upper and lower die holders which are adapted to be automatically rotated approximately 180.degree. to reverse the die orientation and thereby more economically blank the sheet material with a minimum of wastage.
