    摘要: A sheet-representing signal is registered by successive shift-register stages in simulation of the travel of a sheet through a printing machine. Signal detectors connected to different register stages actuate moving units which in turn change the state of activation of the functional units of the printing machine. Upon a changeover from one-side to two-side printing, there arises a sheet travel path length change composed of a fixed component determined by machine geometry and a variable component determined by sheet length. Each moving unit moves cyclically and can move the associated functional unit only during a certain portion of the cycle. Upon a printing mode changeover, moving units undergo a phase shift of their cycles of motion and signal detectors are disconnected from certain register stages and reconnected to others, thereby compensating for the variable and fixed components of the sheet travel path length change.

    摘要: In first and second modes, the arrangement prints on only one side or on both sides of a sheet, respectively. A sheet is transported along a predetermined path through the arrangement and passes printing devices cooperating to effect printing of the sheet. Changeovers from one to the other mode alter a portion of the sheet transport path, changing its length. A control system for the arrangement includes a shift register. When a sheet arrives at a predetermined location along the path, a sheet-representing signal is applied to the shift register. Shifting pulses applied to the shift register in synchronism with sheet travel cause the sheet-representing signal to travel through the shift register in simulation of sheet travel. As the sheet-representing signal reaches preselected shift-register stages, it causes an actuator associated with such stage to actuate a respective printing device. Thus, the printing devices are controlled in dependence upon the arrival of the sheet at predetermined portions of the path. Upon a change of operating mode, a compensating unit is operable for at least partially offsetting changes in the correlation between shift register stages of the shift register and the associated portions of the path.
