Specification and German Patent Application Publication No. 420
From U.S. Pat. No. 8,079, a cleaning device for cleaning a cylinder covered with a rubber blanket is known. If desired, this known cleaning device can be applied to the blanket cylinder. In this case, the cleaning roller is wetted with a cleaning liquid containing a solvent and is guided along the rubber blanket while rotating in the opposite direction to the rotating blanket cylinder.
In the case of a web-fed rotary printing press with two printing devices, i.e. a paper web is guided between two blanket cylinders for the purpose of double-sided printing, the Federal Republic of Germany Patent Application No. 1

According to the method known from DE 53 18 886, the blanket cylinder and the impression cylinder can be cleaned simultaneously in a sheet-fed offset printing press. In this known method, the cleaning device is applied to the blanket cylinder towards the operating position after unrolling the cylinder. In this case, the printing device is operated without running the paper. After starting the cleaning device, the blanket cylinder is placed in the impression cylinder. At this time, the impression cylinder is cleaned via the blanket cylinder, which makes it possible to save the cleaning device dedicated to the impression cylinder for automatically cleaning the impression cylinder and the construction space required for this purpose. However, this known method has the disadvantage that the cleaning process is relatively time-consuming. This is because the blanket must first be cleaned while the blanket makes several revolutions, and only after that can the blanket be inserted into the impression cylinder. Furthermore, since the cleaning effect of the blanket cylinder is relatively small, the cleaning process requires a relatively long time also for this reason.

は、付加的な時間的手間は必要とならない。According to the present invention, two cylinders, for example, a blanket cylinder and an impression cylinder or an impression cylinder and a transfer cylinder can be cleaned simultaneously and in direct contact with the cleaning roller. In this case, it has been found that two cylinders can be cleaned with the device according to the invention in the time required to clean a single cylinder alone in the conventional manner. In this case, the required cleaning time is in each case for the cylinder with the most contamination. Therefore, no additional time is required to simultaneously clean the less polluted second cylinder.

This ensures a uniform application to both cylinders. The peripheral speed of the cleaning roller is preferably set higher or lower than the peripheral speed of both cylinders during the cleaning process. As a result, the cleaning roller can perform relative movement even with respect to the cylinder rotating in the same direction. The direction of rotation of the cleaning roller is advantageously set so as to have an opposite direction to the rotational movement of the more contaminated cylinder.
