    • A method for detecting registering errors for multi-color rotary presses in which register marks (6) are printed on a paper web (7) by each printing section (1), a light source (18) is caused to flash based on a reference signal generated by signal output means (23) operating in synchronism with the rotation of a predetermined plate cylinder (13) for outputting signals, the register marks (6) printed by all printing sections (1) are read as two-dimensional image data via reading means (17) operating in synchronism with the flashing of the light source (18), the two-dimensional image data are developed into matrix data, a first center of gravity is found as an approximate center of gravity of each register mark from the matrix data, a second center of gravity is found as a high-precision center of gravity of each register mark from the matrix data based on the first center of gravity, the second center of gravity of a predetermined register mark is used as a reference to find the relative positions of other register marks, a deviation of the resulting relative positions from the reference relative position is found, and the deviation is regarded as a registering error.

    • The apparatus for controlling, in a power failure, a rotary press (Fig.1) that separately drives a printing section (CT1,CT2) and a folding section (FD) with independent drive sources (M), pulls a printing material (W) that is being braked in a paper feeding section (SP1,SP2) at least by the folding section, brings a blanket cylinder (BC) of the printing section into contact with the printing material to produce printing impressions by changing over the braking of the printing material to a braking mode with a constant braking force upon interruption of power feeding due to a main power failure, detecting a voltage drop caused by the power failure to output a power failure signal, changing over to a battery power supply (12), separating a blanket cylinder that is at press from the printing material, and decelerating and bringing to a halt a printing material pulling mechanism (OT) at the folding section within a predetermined time.
    • 用于在电源故障中控制分别驱动具有独立驱动源(M)的打印部分(CT1,CT2)和折叠部分(FD)的旋转压力机(图1)的装置拉动打印材料(W )至少通过折叠部分在制纸部分(SP1,SP2)中被制动,使印刷部分的橡皮布滚筒(BC)与印刷材料接触以通过改变印刷部分的制动而产生印刷印模 在由于主电源故障而中断供电时以恒定的制动力将制动模式打印到制动模式,检测由电源故障引起的电压降以输出停电信号,切换到电池电源(12), 从打印材料中分离出被压制的橡皮滚筒,并在预定时间内减速并使折叠部分处的打印材料拉动机构(OT)停止。

    • It is an object of the present invention to prevent waste when printing is made on a paper web threaded through a detour web path from a printing unit to a folding unit via other printing units in such a manner that printing images are changed while the web is being transported by changing over a plurality of printing units through which the web is passed. The control section of each printing units having a detour web path is adapted so that it can produce a phase correction value so as to correct a drive reference speed signal with a signal relating to the difference between a drive reference phase and a corrected phase and a feedback speed signal.
