Abstract: A device for controlling a rotary press is provided. The device includes a main evaluation unit which is provided with a main signal inlet, at least a first main signal outlet and a first main transformation device. The device further includes a master generator which is capable of generating a master signal which represents a reference value of the rotary press, and a first interface which is capable of generating a first periodic signal in accordance with the master signal and transmitting this first periodic signal to the main signal inlet.

Abstract: The present invention relates to a safety system comprising at least two stationary detector elements each defining a respective first safety zone, said first safety zones not coinciding, a moving detector element, and a control unit connected to the stationary detector elements. The control unit is adapted to detect the presence of the moving detector element in one of the first safety zones. The invention is applicable to rotary printing presses.

Abstract: A rotary element of a printing press is provided, in particular in a folding apparatus of the printing press, including an encoder for generating a first periodic signal in response to rotation of the rotary element, the encoder being linked to an evaluation unit which has at least one synthesizer for generating a second signal having a resolution ratio, a frequency ratio, and a phase relation to the first signal. The possible uses of the signal generated by the encoder in response to the rotation of the rotary element are expanded and rendered flexible.
