Abstract: A container for a printing blanket comprises a cassette of dimensions sufficient at least to contain a printing blanket in wound form. The cassette comprising a casing of generally cylindrical shape having a longitudinal opening for sheet-form egression of a printing blanket from within the cassette. In one preferred embodiment, the cassette has a pressure slide attached to or integral therewith adjacent to the longitudinal opening, for pressing a printing blanket on a press cylinder when the blanket is fed onto the cylinder. The cassette is employed in the manipulation of large adhesive-backed printing blankets for web-feed offset printing presses.

Abstract: For use in a printing press cylinder (1) of the type having in its surface an axial cavity (2) produced for location of a lock-up device for a printing blanket on the cylinder, there is provided an adaptor fillet to adapt the cylinder for accommodation of a printing blanket without a lock-up device, the adaptor fillet comprising a fillet (3) of a shape for insertion into the cavity so as to bridge the cavity flushly with the cylinder surface periphery, said fillet having an arcuately curved bridge surface (10) of the same radius of curvature as that of the cylinder and having in its bridge surface a longitudinal slit (11) for guidance of a knife edge. In a preferred embodiment of the invention, the fillet is in two-part form, consisting of a lower part (4) securable in the cavity by a threaded fastener entering the cavity base, and an upper part (5) securable to the lower part and providing the arcuately curved bridge surface.
