Abstract
Abstract In a control device for a cyclically operating printing machine, operative for generating time pulses or signals for activating functional units of the printing machine and comprising a pulse generating device, the pulse generating device is formed by an angular encoder connected to a cycle shaft of the machine, and the pulse processing circuit includes a circuit for generating binary addresses corresponding to a rotary speed of the cycle shaft storing predetermined time signals and having addressing inputs, and a PROM memory connected to the circuit for generating binary addresses.
