DEFINITION

Classification: 83/350

(under the class definition) Device including a tool which is actuated in synchronism with advancing work, to cut such work while the latter is passing through the tool station; the tool, during its passage through the work, following a path which is substantially perpendicular to the direction in which the work is moving.

(1) Note. The portion of the work near the cutter may be blocked thereby during and incidental to the cut, causing a buckling or compression of the work. If, however, a patent contains a definite teaching that a dwell is caused in the work motion, such patent will be placed in subclasses 202+, particularly subclasses 262+. Usually the tool stroke* is rapid, and the work springs or falls back to its normal condition between tool strokes.

(2) Note. For a patent to be placed as an original copy in this and indented subclasses, it is not necessary that a work-feed means be claimed if it is evident (from the claimed subject matter) that work is in motion and that a definite timed relationship exists between the work motion and the tool actuation.

SEE OR SEARCH THIS CLASS, SUBCLASS:

202+, for a device in which a tool engages work during the dwell period between successive increments of work-feed, and subclass 262, indented thereunder, for a device wherein work-feed means is operated continuously, but the work is halted during cutting by engagement therewith by a clamp, abutment, or the tool itself, and see (1) Note, above.

284+, for tool having motion component in direction of moving

work, and in particular subclass 349, indented thereunder for rotary transverse cutter with axis offset from work-feed path. 401+, for a device to move work toward a tool station.
