DEFINITION

Classification: 72/348

With additional metal deforming:

(under subclass 347) Subject matter further comprising organized apparatus or a method step of a type which itself constitutes subject matter for this class.

(1) Note. Any other claimed deforming operation, such as die forging, embossing, bending, etc., combined with an operation which qualifies as "deep drawing: is proper subject matter for this subclass. (Often a portion of a tool couple effects deep drawing, while other portions operate in other ways upon the same work, as for flanging, bending, embossing, etc.).
