ABSTRACT:
A sheet metal workpiece is deformed by embossing or shearing over a patterned die plate, by placing the workpiece on the die plate, a slab of rubber or other elastomer on the workpiece, and passing between spaced parallel driven rollers.
A characteristic of the invention is the use of load rollers adjacent and on each side of the lower roller to support a carriage which itself supports the die plate so that the resilient forces imposed by the rubber do not curve the carriage and die plate.
