Abstract
Rubber blanket sleeve for a channel-free rubber blanket cylinder of an offset printing machine and process of producing rubber blanket sleeve. The rubber blanket sleeve includes an inner, dimensionally stable support sleeve arranged as a supporting layer, and a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm . The elastomer layer includes a rubber matrix having a tensile stress of greater than about 2.2 N/mm and less than about 15 N/mm with 100% elongation. An outer covering rubber layer is arranged as a printing layer. All of the layers are composed of seamless, cylindrical bodies and are coupled to one another. The process includes arranging an inner, dimensionally stable support sleeve as a supporting layer, and positioning a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm over the support sleeve. The elastomer layer includes a rubber matrix having a tensile stress of greater than about 2.2 N/mm and less than about 15 N/mm with 100% elongation. The process further includes arranging an outer covering rubber layer as a printing layer, such that all of the layers are composed of seamless, cylindrical bodies and are coupled to one another.
