ABSTRACT:
The present invention is a bending machine for bending material such as steel to form cutting dies for products such as cloth, leather or the like. Coiled material is fed through a material washer, straightener and printer by a material feeder to a bending head. If required the material is forwarded through the bending head to a heating unit and retracted to the bending unit to aid in bending. A nicking tool is also provided ahead of the bending tool to nick the material. The nicks enable the cutting die to cut notches in the product being cut. A support surface at the output end of the machine supports the material as it is bent into the required form.
