Abstract
A stylus is mounted on a carriage which also supports a work plate adapted to be positioned beneath a punch. When the punch first strikes the work plate, the stylus is automatically retracted out of a hole in a template so as to free the carriage to shift forwardly in unison with the work plate as the punch continues through the plate.
