  • the removable sleeve-shaped rubber blanket can be moved axially through the opening in the frame. Inside the in this writing described blanket cylinders are also provided air lines through which air the outer surface of the blanket cylinder is guided. From that with compressed air in this way, air flows to the inside of the blanket cylinder Inside of the rubber blanket so that it can be pushed onto the Blanket cylinder is stretched. After pushing the rubber blanket onto the The blanket cylinder can be switched off the compressed air supply. Thereupon contacted the blanket the outer surface of the blanket cylinder and encloses the Blanket cylinder firmly. To remove the rubber blanket, it is again with Compressed air is applied and removed manually.
  • a disadvantage of the printing press described in this document is that the The inside surface of the blanket or the outside surface of the blanket cylinder is dirty can be, for example, by printing ink or other substances that are on the The inner surface of the rubber blanket remains undetected. This will remove the Blanket by applying compressed air to the inside of the blanket axial pulling of the rubber blanket difficult. Furthermore, manufacturing-related Defects as well as the environmental conditions such as humidity and temperature Impact the removability of the blanket.
  • US 4,913,048 is a printing press with a sleeve-shaped, channelless Printing form or printing plate described, which can be provided with a print image.
  • This sleeve-shaped printing form is axially removable from the plate cylinder and can by Elongation of the printing form by printing a printing medium on the plate cylinder be applied. The sleeve-shaped printing form is then manually placed on the Plate cylinder pushed on and relieved of pressure.

  • the present invention can be used in particular in connection with axial removable rubber blankets such as those in US 5,429,048 and US 5,323,702 are described. Due to the compressibility of the outer layer of the rubber blanket a secure gripping of the rubber blanket achieved by the device without the inner sleeve of the rubber blanket is compressed, causing undesirable friction between the inner sleeve and the blanket cylinder would cause the Removing the rubber blanket is usually difficult. In addition, it is also possible that the device for removing the pressure sleeve the sleeve on the Rubber blanket engages opposite side of the sleeve to damage the Avoid blanket surface or to get a slightly smaller diameter.
  • the clamping arms preferably grip the outer surface of the pressure sleeve.
