Abstract
In a rotary printing machine the printing cylinder (1) is supported on a flexible band (6) under tension, printing ink being introduced into the gap (8) between the band (6) and the printing cylinder. This facilitates the hydraulic mounting of the printing cylinder (1) while reducing the load on the cylinder shaft journal mounting (2) and prevents deformation of the cylinder, and also ensures even ink coverage of the printing cylinder surface.
Claims15
A rotary printing machine having a printing cylinder (1), pressable relative to a counter roller (4), which is provided with at least one flexible band (6) and with an ink supplying apparatus (9) for supplying printing ink to the surface of the pressing cylinder (1), wherein the printing cylinder (1) is supported upon the at least one tensioned flexible band (6), and wherein printing ink is supplied into a gap (8) between the band (6) and the printing cylinder (1), with the printing ink being distributed, during the rotation of the printing cylinders (1), over the surface of the printing cylinder (1), at an engaging surface of the printing cylinder (1) upon the band (6), wherein, at the same time, hydraulic lubrication for bearing means of the printing cylinder (1) is formed upon the band (6).
