DEFINITION

Classification: 83/869

Edge trimming (e.g., chamfering, etc.):

(under subclass 861) Method or apparatus wherein the tool utilized functions to remove a portion of work defined by the junction areas of a thickness and a nonthickness face.

(1) Note. Excluded from this subclass is a patent for a process or apparatus for merely slitting such a junction area, as the operation of slitting itself is not considered to entail removal of a work portion. However, a patent may properly be placed herein where a plurality of slitters coact to remove a portion of edge material.

(2) Note. In general, the patent of this subclass discloses removal of a work portion planarly by a single tool. However, a patent directed to the formation of an edge furrow or channel, by either a single tool or multiple tools, would be admitted to this subclass.
