DEFINITION

Classification: 83/724

(under subclass 722) Device including means to effect movement of the pusher elements away from the cutting plane.

(1) Note. The retraction of the pusher elements away from the cutting plane is generally for the purpose of preparing the devices for the receipt of a new work piece.

SEE OR SEARCH THIS CLASS, SUBCLASS:

714+, for a similar device wherein the means which advances the work toward the cutting plane (e.g., pusher element) physically retracts the work from the cutting plane as well.
