(under subclass 1) Processes which include a step of
providing a line of lesser strength in the work, and then severing the work on a line which intersects or coincides with the line of lesser strength.
(1) Note. The preliminary weakening may be of a type not classified, per se, in this class; as for example, perforating, milling, cutting by a torch or scoring. Such steps in combination with breaking or tearing steps have been classified here because such other step has been considered to effect a necessary or desirable preparation of the work for the breaking or tearing operation.
