Abstract (en)
[origin: EP0788879A1] The rotary printing machine has the printing cylinders (16) at each printing station (1,2,3) directly driven by a vectorial asynchronous motor (26) controlled by an electronic circuit (101) regulating angular position. The set angular position is delivered over time from a central synchronisation controller. The assembly of cylinder, shaft and rotor is mobile in axial translation, to allow correction of lateral position of the printing plates or the cylinder. Reference marks printed by each station are monitored to determine the misalignment. Errors are corrected by an adjuster mechanism (35) driven by an electric motor (25). An angle encoder on each shaft provides rotational position information.
