Abstract
A printing cylinder with a rubber coating for letterpress, flexography, rotogravure, and rotary offset. To reduce channel beat or engagement impact, the outer layer of the rubber coating is shorter at the tensioning-in edges than the inner layer and is at an angle of at most 90.degree. to it at both ends. It has a non-twisting tensioning mechanism with a narrowed introduction slot at the tensioning channel.
