Abstract

A device for generating timing pulses for a rotary printing machine includes generators for generating synchronizing pulses and a pulse sequence corresponding to increments of angle of rotation of the machine. A pulse processing circuit includes address counters connected to the pulse generating means and being preset by an address presetting device. The output of the one address counter is connected to a PROM storing predetermined sequences of timing pulses. In order to provide for shifting of the stored timing pulse sequences in a negative direction, an inverting member is connected in the data bus between the rotary speed counter and the address presetting device of the one address counter. The inverting member can include either negators or storing means programmed with complementary values.
