DEFINITION

Classification: 156/510

(under subclass 349) Apparatus combined with means to penetrate a workpiece for the purpose of severing or making

an opening therein.

(1) Note. The severing operation may take place before, during or after the laminating step and may be caused by means separate from the laminating means or the same means.

(2) Note. The severing may be, for example, to shape an article from stock, to trim off excess, to punch out workpiece from a stock strip, etc..

(3) Note. The severing is usually by means of a solid member. Cutting by means of a gaseous stream is provided for in subclass 497 above.
