• a temperature-controlled printing form cylinder is known, the interior of which is completely filled with a liquid, the liquid passing through a first circuit running outside the printing form cylinder, a preferably coil-shaped cooling tube penetrating the liquid over the entire cylinder width, with a cooling medium flowing through the cooling tube and connected to a second circuit cools the liquid and thus the cylinder.
• DE 93 06 176 U1 discloses a cylindrical rotary body for printing presses which can be tempered by introducing water vapor and in which bores or lines are arranged close below its lateral surface along the rotary body, the bores or lines having a course deviating from the axial parallelism and thus a slope z. B. may have to the center of the rotating body.
• a temperature-controlled printing form cylinder which has in its interior casting core chambers which extend across the cylinder width and are closed by covers on the end faces of the cylinder body, a tube extending across the cylinder width being arranged in each chamber, wherein in a cylindrical pin in an axial bore, a sealingly displaceable tube unit connected to a rotary leadthrough for the supply and removal of a coolant is introduced, each tube being connected to the tube unit on the end face of the cylinder equipped with the tube unit via a radial bore, the feed unit being supplied with Coolant flows through the pipes and pours into the hollow casting core chambers in the area of the opposite end of the cylinder and is discharged from there via a radial bore connected to the pipe unit.
• EP 0 557 245 A1 discloses a temperature-controlled, approximately full-walled cylinder for a rotary printing unit which has a first line along its axis of rotation and a plurality of second lines connected to the first line, just equidistantly arranged in the circumferential direction and parallel to the axis of rotation, connected to the first line along its axis of rotation has, through which a liquid can flow for tempering the lateral surface.
• EP 0 652 104 A1 discloses a temperature-controllable cylinder for a rotary printing unit, which has a cylinder jacket tube, on the end faces of which a flange is arranged, a separating tube and an inflow tube extending inside the cylinder coaxially with its length, a cavity forms a cooling chamber between the separating tube and the cylindrical jacket tube, which is formed by a via the inflow tube supplied coolant is flowed through, the line in the separating tube being connected to the cooling chamber via connecting bores in one of the flanges.
• a sheet guide drum for sheet-fed rotary printing presses is known, a support plate, which is supported with a plurality of resiliently supporting elements or supports, being arranged on a transfer drum, the support elements or supports being inclined relative to the transfer drum, and with a circumferential direction of the Guide drum directed clamping of a jacket film lying on the support plate, a radial height of the support plate formed by the support elements or supports is adjustable, in particular can be reduced.
• a blanket cylinder for an offset printing machine is known, a blanket stretched on the blanket cylinder extending over a recess provided on the blanket cylinder as a relief device.
• the invention has for its object to provide rotary body of a printing press with a bale.
• FIG. 5 shows a rotary body of a printing press according to a variant of a third embodiment with a base body and a solid outer body applied thereon, wherein cavities covered by the outer body are introduced into the base body; 6a shows a rotary body of a printing press according to a fourth
