Abstract

A tape punch machine in which several subassemblies are arranged for accurate adjustment and easy detachment; to assure accurate and reliable tape movement a stepping motor for feeding the tape receives two pulses for each spacing increment of the tape. The punches are selected by interposers which are not released if the same punch function is to be repeated in successive cycles of the machine.
