DEFINITION

Classification: 493/142

Work advancing during pressing:

(under subclass 141) Method or apparatus wherein the workpiece is moved through the apparatus as the work portions are forced together.

(1) Note. Movement of a workpiece toward a working tool to effect a treating operation is considered to be work infeed rather than work advancing and is therefor not the concept of this subclass.
