DEFINITION

Classification: 83/254

(under subclass 253) Device provided with means to cause two or more stops to become effective in serial relationship to position the work for successive tool cycles.

(1) Note. The plurality of work stops are so disposed and/or moved that not all of such stops are brought into work-abutting and stopping position for any one tool cycle and the identity of stops in such position varies cyclically.

238+, for means to produce unequal work-feed increments in recurring series.

278, for some disclosures of work-moving pusher elements which are successively effective.

393, for work stopping abutment(s) with cyclic means to alter work-stopping position between tool strokes.
