DEFINITION

Classification: 83/703

(under subclass 401) Device including means for sequentially moving the work in two distinct directions, namely (a) work infeed motion along a path parallel to the plane of cut, and (b) transverse work motion in a direction generally perpendicular to the plane of cut; and wherein movements (a) and (b) are repeated.

(1) Note. For the purpose of this definition, the means which permits movement of the work transverse to the plane of cut must have structure which at least facilitates such movement, e.g., work pusher, or a guide-like groove or track.

SEE OR SEARCH THIS CLASS, SUBCLASS:

284+, for a cutting tool which moves in two directions, namely (a) perpendicularly toward the work, and (b) parallel to the direction of movement of the work ("flying cutter").
