.~.~.~ With undulant cutting edge (e.g., "pinking" tool)
DEFINITION
Classification: 83/333
(under subclass 331) Device provided with a cutter including a cutting edge on the periphery of said cutter, in which a development (in the sense of the term as used in descriptive geometry) of the cutting edge from said periphery into a plane forms a zigzag or sinuous line.
(1) Note. Included herein are rotatable circular cutters known in the art as "pinkers", "pinking wheels" and "pinking machines". The terms are so well known that the shape of the edge as defined above is rarely recited precisely; hence mere
recitation in the claim (s) of such art terms or similar terms is considered sufficient for classification herein.
(2) Note. Patents in which the cut is of the form known as "scalloped" will also be found herein.
SEE OR SEARCH THIS CLASS, SUBCLASS:
428, for a device which produces an undulant cut by reciprocating a slitting blade laterally of the direction of work-feed.
