DEFINITION

Classification: 493/201

With means to advance work or product:

(under subclass 200) Method or apparatus combined with use of means to transport a workpiece progressively from a remote location toward or through a treating station or to transport a formed receptacle away from a treating station.

(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.
