Abstract

Paper tape, in roll or endless belt form, is prescored to provide a control tape that can be individually programmed by the user to perform a desired control operation. The prescores are removed by a stylus, without need for a paper tape punching device. The paper tape has timing track 1 defined by a plurality of equally spaced longitudinally extending notches and five data bit channels 2...6. Each of these comprise a prescore at predetermined index points transversely aligned with a corresponding one of the notches of track 1. The prescores are selectively removed to provide control according to a conventional five-bit code. The timing track can be eliminated and the number of data bit channels can be arranged for use with other conventional codes.
