Abstract
A method and apparatus for identifying and detecting the end of a wire segment in a computer controlled harness maker in which the wire is crimped twice in close proximity 90 degrees apart thereby forcing the wire next to the crimp to enlarge in size. The crimped wire is then pulled between two surfaces of the pinch mark detector which are spring loaded and rides at the nominal wire diameter until the crimp passes through the pinch mark detector depressing a plunger to activate a metal sensitive proximity switch providing an output signal representative of a pinch mark detect condition.
