DEFINITION

Classification: 72/331

Severing (e.g., subdividing):

(under subclass 326) Subject matter, note provided for in preceding subclasses, comprising the detachment of a discrete piece of material from stock, work, or a product of metal deformation.

(1) Note. This subclass accommodates shearing operations by composite tool in which metal deformation is accompanied by cutting for such purposes as (a) reduction of scrap, (b) subdividing a multiple product, (c) notching, (d) detaching product from end of stock, or (e) squaring or trimming a rough blank, etc., as distinguished from the blank detaching from stock in subclass 330 above.

338+, for metal deformation with associated severing by means other than shears.
