Definitions

  • the description relates to a printing plate cylinder with a cylinder core made of metal, on which a carbon fiber-containing sleeve is arranged.
  • the print length is due to the effective diameter of the printing plate cylinder carrying the clichés. Not for a special cylinder with the respective associated printing length Bearing constructions are needed, it is known on the peripheral surface of the To slide on a replaceable sleeve called a sleeve, which then determines the effective diameter and thus the print length.
  • EP-A-0 732 201 a printing plate cylinder of this type is described in which the sleeve has a multilayer structure. Two layers from one composite material reinforced by carbon fibers form a gap, which is foamed with plastic. The inner surface of the sleeve lies full on the circumferential surface of the steel cylinder core, so the relatively high radial forces occurring during the printing process due to the relative soft foam layer of the sleeve through on the rigid Cylinder core can be transferred.
  • a disadvantage of this construction is that with the help of the sleeve only a limited increase in print length is achieved because larger ones Print lengths, the layer thickness of the sleeve would be so great that the necessary stiffness and dimensional accuracy of the outer surface of the sleeve is no longer guaranteed could be.
  • Another disadvantage is that the replacement of the sleeve is relatively labor-intensive, since the sleeve covers the entire surface rests on the cylinder core and thus when pushed on or pulled off high friction forces have to be overcome. To reduce these frictional forces it is known to introduce compressed air into the interior of the cylinder core, the via radial openings in the space between the cylinder core and Sleeve enters.
  • EP-A-0 769 373 describes a printing plate cylinder in which the sleeve, which determines the printing length with stub axles at both axial ends has a smaller diameter and is stored directly in the machine frame.
  • a steel shaft extending through the sleeve extending from the sleeve Distance is only used to change the sleeve when changing the sleeve lift out of the bearings and hold so that they are axially withdrawn from the shaft can be.
  • a paper clamping cylinder which passes through a sleeve is made of fiber-reinforced plastic and two washers that form the sleeve Complete at the ends and be traversed by an axis.
  • the sleeve is made of a plastic sheet, which is heated around a mold core and then closed into a tube.
  • the object of the invention is to provide a printing plate cylinder in which the print length varies by changing the sleeve over a wide range can be without affecting the print quality.
  • This object is the input in a printing plate cylinder mentioned type in that the sleeve is self-supporting and by im Area of both ends arranged at a distance from the circumferential surface of the Cylinder core is held and that the carbon fiber-containing material of the sleeve Carbon fiber composite material with a wound structure made of carbon fibers.
  • the term "self-supporting" in this context means that the sleeve has such a high degree of inherent rigidity that, although only at the ends is supported by the disks on the cylinder core, those that occur during printing Can withstand radial forces, so that occurring in the sleeve Deformations remain within the permissible tolerance limits. It has shown, that this property of the sleeve through the use of a carbon fiber Reinforced material can be achieved in which the carbon fibers form a wound scaffold.
  • the sleeve is relatively low, which has a favorable effect on the smooth running of the printing press and the manageability of the sleeve or the entire printing plate cylinder affects. Since the sleeve is at a distance from the circumferential surface of the cylinder core is held, the effective diameter of the sleeve is not as in conventional Sleeves determined solely by the layer thickness of the sleeves, but it is determined by the distance between the sleeve and the cylinder core certainly. This allows the use of sleeves with a relatively large size Diameters, so that correspondingly large print lengths can be achieved.
  • Another advantage of the invention is that the sleeve is essential can be removed more easily from the cylinder core, since they are only arranged at the ends Disks is supported on the cylinder core, so that only relatively small Frictional forces occur.
  • the two disks can be made from a different material from the sleeve Material, for example made of steel or aluminum. You can however, optionally also consist of the same material as the sleeve or even be formed in one piece with the sleeve. It is also possible to form these washers bearing pins with which the sleeve directly in the machine frame is stored.
  • the cylinder core is also one without the Sleeve insertable printing plate cylinder.
  • the printing plate cylinder can be set to a minimum print length by simply using the Sleeve is omitted.
  • the clichés can then be on a conventional one Be arranged sleeve that is pushed onto the printing plate cylinder, however, they can optionally also directly on the peripheral surface of the cylinder core be stretched.
  • the cylinder core preferably has a compressed air line in a manner known per se lead from the radial openings to the peripheral surface.
  • a compressed air line When not used according to the invention of the cylinder core without a sleeve is the pushing or pulling one conventional sleeves easier.
  • the possibility in the space between the cylinder core and to generate an overpressure of the sleeve Through radial breakthroughs in the The sleeve can then also be pushed onto the conventional sleeve The outer circumference of the sleeve can be facilitated.
  • the compressed air system can also be used to preload the sleeve from the inside to the To influence the crown of the sleeve.
  • the printing plate cylinder shown in Fig. 1 has a cylinder core 10 which preferably formed by a conventional steel printing plate cylinder is and is provided at both ends with stub axles 12, the storage enable in a machine frame, not shown. Furthermore points the cylinder core 10, as is known per se in printing plate cylinders, one Axial bore 14 on, can be supplied via the compressed air, which then radial openings 16 emerge from the peripheral surface 18 of the cylinder core can.
  • the cylinder core 10 is surrounded at a distance by a cylindrical sleeve 20, which is formed by a tubular body made of carbon fiber composite material becomes.
  • a tubular body made of carbon fiber composite material have been used, for example as web guide rollers in printing machines or, if necessary also used as a printing plate cylinder for shorter printing lengths.
  • this tubular body is a scaffold made of diagonally wound carbon fibers, which a matrix of plastic are embedded.
  • the sleeve 20 is at both ends by flat washers 22 made of steel or aluminum completed and is supported only by these discs on the cylinder core 10 from.
  • the disks 22 are non-rotatably connected to the cylinder core 10, as symbolized in the drawing by wedges 24.
  • the sleeve 20 rotatably connected to the disks 22, so that the cylinder core 10 and the sleeve 20 together a rigid, bending and torsional stiffness Form the pressure plate cylinder.
  • Clichés not shown can refer to the outer Circumferential surface of the sleeve 20 are clamped.
  • the sleeve 20 but also a conventional sleeve can be slipped on, which in turn carries the clichés.
  • the sleeve 20 openings 26 with which those from the openings 16 of the cylinder core escaping compressed air to the peripheral surface of the sleeve can be forwarded.
  • the dimensions of the printing plate cylinder can be in a wide range vary.
  • By changing the sleeve 20 including the associated one Disks 22 can be especially the outer diameter of the printing plate cylinder change in a wide range. Because of the relatively small Wall thickness of the sleeve 20 and the low specific weight of this sleeve takes the total weight and the moment of inertia even with large outer diameters of the printing plate cylinder not significant.
  • the working width of the printing plate cylinder is about 800 to 2000 mm, the diameter of the cylinder core 10 about 100 mm, corresponding to a minimum print length of the order of magnitude not according to the invention of just over 300 mm, and the outer diameter of the sleeve 20 for example up to 400 mm.
  • the wall thickness of the sleeve 20 is in the On the order of 15 to 20 mm. Because of the carbon fiber reinforced This wall thickness is sufficient, the required inherent rigidity of the material Ensure sleeve 20. The one when printing on the outer surface of the sleeve Radial forces acting are introduced into the two disks 22 without that the sleeve 20 deforms significantly.
  • the disks 22 are flush with the ends of the sleeve 20, 2 shows an embodiment in which the disks 22 face each other the sleeve are slightly indented.
  • the discs 22 will have a better distribution of the support forces on the Length of the sleeve 20 and thus a significant reduction in printing reached bending moments acting on the sleeve 20.
  • they are bending moments acting on the cylinder core 10 slightly increased, but lift these effects do not affect each other, but the end result will be higher Bending rigidity of the pressure plate cylinder reached.
