DEFINITION

Classification: 242/522

With cutting, perforating, or notching:

(under subclass 520) Subject matter comprising an instrument (cutting device) to penetrate the elongated material to divide, score, or provide a permanent puncture in the material, after which at least part of the original material is wound onto the take-up.

(1) Note. Patents proper for this and the indented subclasses should claim a significant cutter and structure for subsequently winding the cut material; however, nominal cutting followed by significant winding is provided for later in this class, whereas unwinding to cutting structure is

provided for in other classes.
