DEFINITION

Classification: 225/96

(under subclass 94) Devices in which a nonbreaking tool partially separates the product from the work, as by perforating or scoring, or otherwise provides a line of lesser strength, which line intersects or coincides with a line of separation effected by the breaking means.

(1) Note. The preliminary weakener may be of a type not classified, per se, in this class; as for example, a cutting torch, a milling tool or a scoring device. Such tools in combination with a breaking device have been classified here because such other tool has been considered to effect a necessary or desirable preparation of the work for the breaking operation.

2, for corresponding methods.

95, for devices which initially contact the work with a sharp tool to begin a line of separation and complete a severance by a dull tool, which dull tool may be a breaking tool.
