DEFINITION

Classification: 72/375

Complementary:

(under subclass 374) Process using apparatus which includes opposed shaping tools whose work-engaging surfaces are generally of similar and mating or interdigitating form (allowing for the thickness of the work), so that a shape product corresponding to the tool shape and of generally uniform thickness results.

(1) Note. The patents found here are mainly directed to shaping (e.g., embossing) sheet metal.
