.~.~> Including means to rotate both elements of tool pair {2}
DEFINITION
Classification: 83/491
(under subclass 469) Device provided with means to effect rotational movement of the cutter (either unidirectional or to-and-fro in the arc of a circle).
(1) Note. This subclass excludes patents in which one cutter is frictionally rotated by mere contact of the cutting edge of the cutter with the cutting edge of another cutter. For examples of this type of patent see subclasses 485+, 486+ and 487+.
(2) Note. Other patents which include means to rotate the cutter are to be found in subclasses 426+ in which the cutter is driven by or with the work moving means, and in subclasses 488 and 489 in which the cutter is rotated by or with the carrier moving means.
