DEFINITION
Classification: 83/917
Cutting one or more products from one edge of a workpiece, leaving portions of the original edge intact.
(1) Note. A notch is a nonlinear cut through the thickness of a workpiece, extending inwardly from one edge of the workpiece and returning to the same edge.
(2) Note. The notch may be cut in an exterior or an interior edge of work.
(3) Note. The severing of work along a desired line of cut by a succession of overlapping notches is called "nibbling",
for which see subclass 916 of this class; or, if done in the form of a nonlinear repetitive pattern which leaves none of the original edge intact, is called "pinking" or "scalloping", for which see subclass 918.
(4) Note. Key cutters (notchers) are found here, rather than in subclass 908.
