  • Publication number: 20010018872
    Abstract: A rotary printing press control method receiving a drive reference from a master control section, generating a phase correction based on dividing a length between a printing unit and a folding unit by an outer peripheral length of a printing cylinder of the printing unit, generating a drive reference speed signal based on the drive reference, generating a corrected drive reference phase signal obtained by correcting a drive reference phase based on the drive reference with the phase correction, generating a feedback speed signal and a feedback phase signal based on the operating condition of the printing unit, generating a phase difference signal based on a phase difference between the corrected drive reference phase and the feedback phase signal, and correcting the drive reference speed signal and the feedback speed signal to control a drive for the printing unit.
