Abstract: A device and method for applying a flexible layer to rollers, as used in graphics machines, such as printing presses or coating machines, whose roller bodies consist of a carrying tube (3). A tubular, flexible body (14) is provided which is pushed over a support tube (1) that is axially connected to a transition piece (2) and a carrying tube (3). In the area of the transition piece (2), compressed air is admitted and is discharged at a discharge force, to generate an air cushion (15) between the tubular, flexible body (14) and the carrying tube (3), over which the tubular, flexible body (14) is pushed.

Abstract: A method and device for adhesive rolls for a roll-reversing mechanism of web-processing machines, particularly w-fed [rotary] printing presses. A flexible tube-shaped piece (14) consisting of a soft elastic material is shifted onto a support tube (1), which is axially joined with a transition piece (2) and a tube support (3). In the region of transition piece (2), compressed air, which has been introduced, flows out, to creates an air cushion (15) between the flexible tube-shaped piece (14) and the tube support (3) onto which the flexible tube-shaped piece (14) is shifted.

Abstract: A rotary printing machine, in particular in a reel-fed newspaper offset rotary press is provided with a device for correcting the web width. A rotatively mounted rotational body configuration is arranged in the path of the web between two print printing nips (2, 3) on one side of the web. The rotational body configuration (5; 6) has a wave-like profile that is transverse to the running direction of the web.

Abstract: A rotary body for compensating the fanout in a printing press. The rotary body forms alternatingly foot sections and head sections projecting over the foot sections by radial height differences along an axis of rotation. The rotary body is a torsion-proof connection of parts or is a one piece structure. The radial height differences increase in the circumferential direction from minima, which they have along a first straight line offset in parallel to the axis of rotation, to maxima, which they have along a second straight line offset in parallel to the axis of rotation.

Abstract: A fanout compensator for a printing press, which comprises a rotary body formation, which has foot sections and head sections alternatingly next to each other along a longitudinal axis. The foot sections and head sections form a wave-shaped surface in order to deform a web to be printed on. The web wraps around the rotary body formation, in a wave-shaped pattern at right angles to the direction of conveying of the web. Fluid channels, which open on the surface of the rotary body formation, are formed in the rotary body formation. The rotary body formation has a fluid connection connected to the fluid channels in order to guide a pressurized fluid to the fluid channels and through the fluid channels to the surface of the rotary body formation.
