A central timing device for controlling a plurality of working functions of a printing machine, includes a reference pulse generator, assembled to encoder discs connected to a cycle shaft of the printing machine to produce a sequence of angular increment pulses and at least one single synchronizing pulse. The reference pulse generator is connected to a pulse processing circuit which includes a first address coding device for producing binary coded addresses pertaining to angles of rotation of the machine. A second address coding device is coupled to the encoder for angular increments via a timing circuit including an AND-gate and a monostable multivibrator to produce binary coded addresses pertaining to the angle of rotation/rotary speed of the printing machine. The outputs of the first and second address generating devices are connected to addressing inputs of separate PROMs preprogrammed with desired timing signals.
A timing device for controlling the operation of a printing machine, including a reference pulse generator for generating a sequence of pulses related to a working cycle of the printing machine, the reference pulse generator including a first generator of pulses corresponding to incremental angles or rotation of a part of the printing machine, at least one second generator of singular synchronizing pulses corresponding to a present angular position of said part of the printing machine, and a pulse processing device comprising a first address coding device coupled to the first generator for producing binary coded address pertaining to said angles of rotation, a second address coding device coupled via a timing circuit to the first generator for producing binary coded addresses pertaining to angles of rotation/rotary speed of said part of the printing machine, and at least two programmable read only storing devices connected, respectively, to the first and second address coding devices to read out preset timing data stored at the addressed locations.
