摘要

A marker for signalling cutting line sensing means is placed on a pattern piece a predetermined distance ahead of a salient corner or a notch. In response to such signal, an alternate cutting tool program control circuit is actuated to substitute for the normal control circuit to effect preprogrammed movement of the cutting tool to cut such corner or notch and then to traverse the tool forwardly until the sensing device has been reoriented to again take over cutting tool control.
