Abstract
A sleeve-shaped printing element for mounting on a carrying cylinder in a printing unit of a web-processing rotary printing machine. The element includes a structure formed of material permitting radial expansion of the sleeve-shaped printing element, the carrying cylinder has an elongated axial extent and being formed with ducts for discharging an expansion medium. The ducts open on a circumferential surface of the carrying cylinder, and the expansion medium is pressurizable by a pressure source. The sleeve-shaped printing element is formed with an inner diameter increasing from one end to the other end of the printing element, and is formed with an at least approximately constant wall thickness; and a combination of the printing element and the carrying cylinder.

A sleeve-shaped printing element for mounting on a carrying cylinder in a printing unit of a web-processing rotary printing machine, comprising a structure formed of material permitting radial expansion of the sleeve-shaped printing element, the carrying cylinder having an elongated axial extent and being formed with ducts for discharging an expansion medium, said ducts opening on a circumferential surface of the carrying cylinder, and said expansion medium being pressurizable by a pressure source, the sleeve-shaped printing element being formed with an inner diameter increasing from one end to the other end of the printing element, and being formed with an at least approximately constant wall thickness.
A sleeve-shaped printing element serving as one of a transfer cylinder sleeve and a printing-form cylinder sleeve on a carrying cylinder of a web-processing rotary printing machine, comprising devices for radial expansion of the sleeve-shaped printing element as it is being mounted on the carrying cylinder, the sleeve-shaped printing element having material characteristics varying in a direction of mounting thereof on the carrying cylinder so that a drive-side end of the sleeve-shaped printing element is more readily expansible than an operating-side end thereof.
