DEFINITION

Classification: 83/259

(under subclass 202) Device which functions to move work by gripping engagement between a surface of the work and a surface of a continuously rotating reciprocating or oscillating member, the dwell being caused by separation of the frictionally engaged surfaces.

(1) Note. Subclass 260, indented hereunder, includes patents disclosing mutilated feed rolls to cause the intermittent feed.

(2) Note. This subclass includes feed grippers which during their advancing motion, release the work to effect the dwell as the grippers continue to reciprocate or oscillate between advanced and retracted positions.

SEE OR SEARCH THIS CLASS, SUBCLASS:

259, for dwell caused by directly clamping or blocking the work.

260, and see (1) Note above.

269, for slippage of feed means on work, after work has engaged a stop or abutment.
