.~ With abutment to position work being fed with respect to cutter {1}
269
.~.~ With slip between positioned work and feed means
DEFINITION
Classification: 83/269
(under subclass 268) Device wherein the feed means continues to move (and slips on the work), upon work contact with a stop element, the frictional driving engagement of the feed means with the work being overcome (interrupted) by the halting of the work in the feeding area.
(1) Note. Devices found in this subclass provide for slippage of the feed means on the blocked work rather than slippage at some point in the drive train.
SEE OR SEARCH THIS CLASS, SUBCLASS:
262, for continuously driven feed means and work clamp or stop, with no provision for slippage (work must buckle up or distort).
350+, for continuously fed work acted upon by a transversely moving tool, with no provision for slippage (work must buckle up or distort) and work movement is checked only momentarily as an incidental effect of contact therewith of the tool.
