Abstract

Abstract A workpiece is continuously indexed relative to a cyclically operable punch, programmed by a pattern control system to automatically control punch operations. A code pattern wheel is intermittently advanced while operation of the punch is interrupted, to generate pulse signals that space the locations on the workpiece at which punch operations are performed.
