DEFINITION

Classification: 83/276

(under subclass 202) Means including a member which engages and advances bodily with the work towards the cutter.

(1) Note. The work-feed means may reciprocate; i.e., travel along the same path on its return stroke as it traveled in its feeding stroke; or it may return from its feeding stroke along a different path (such as a "four motion" feed, or an endless belt conveyor).

(2) Note. The work engaging member may undergo a return movement after each feed increment, or after a succession of work-feed increments.
