摘要： Printing press cylinders are washed with a washcloth which is selectively wound forward and backward between a rotatable supply drum and a rotatable takeup drum. The washcloth is thereby cyclically pressed against a surface of a respective cylinder of the printing press in the washing operation and it is transported onward onto the takeup drum. The washing operation is controlled by detecting, with a sensor system, a transport distance of the washcloth and furnishing, with the sensor, a transport distance signal. The system is initialized by checking whether or not the insert is present and/or whether or not the insert carries enough fresh washcloth. This is done by winding the washcloth forward and back by a given distance. During the ongoing washing operation the transport speed of the washcloth is continously determined from the transport distance signal and comparing with a predetermined lower value and a predetermined upper value. When these thresholds are met or exceeded, the washing operation is terminated or the printing press is stopped.

摘要： A device for guiding signatures between signature-guiding cylinders in a folding apparatus of a rotary printing press includes a guide member extending over the length of the signature-guiding cylinders for receiving signatures thereon, the guide member being disposed relative to the signature-guiding cylinders so as to facilitate a reversal of transport direction of the signatures, a support member whereon the guide member is rotatably supported, at least one conveyor belt for driving the guide member, and a device for applying negative pressure, during rotation of the guide member, to peripheral regions of the guide member and between the guide member and a respective signature received thereon.
