Definitions

  • the invention relates to a printing plate for a printing press according to the preamble of claim 1. Furthermore, the invention relates to a blanket plate for a printing press according to the preamble of claim 9.
  • Printing units of printing presses have a forme cylinder and a transfer cylinder, wherein on a forme cylinder at least one printing forme and on a transfer cylinder at least one transfer mold is arranged.
  • Printing plates are usually designed as printing plates and transfer forms as blanket plates, which is why a forme cylinder is also referred to as a plate cylinder and a transfer cylinder as a rubber cylinder.
  • Printing plates and blanket plates are mounted or clamped on the respective cylinder of a printing unit of a printing press, for which purpose the printing plates and blanket plates have the same angled leading and trailing ends with respect to a plate-shaped base body. Should z. B. a pressure plate are clamped on a forme cylinder, the leading end and the trailing end of the pressure plate are introduced into at least one clamping channel of the forme cylinder and clamped in the respective clamping channel via a clamping device integrated in the same.
  • leading end and the trailing end are angled such that they include a relatively acute angle of less than 45 ° with the main body.
  • a tensioned pressure plate to be changed and this with the leading end and the trailing end cooperating clamping devices are released, block the leading end and the trailing end in the clamping channel and then manually must be removed from the same. This affects an automated change of the printing plate and must be avoided. The same problem occurs even when blanket plates are to be changed automatically.
  • the present invention is based on the problem to provide a novel printing plate and a novel blanket plate for a printing press.
  • the leading end and the trailing end each include an angle between 85 ° and 90 ° with the side of the main body.
  • both the leading end and the trailing end with one side of the basic body include a defined angle between 85 ° and 90 °. This avoids that the leading end and the trailing end block in the chip channel during automated plate change. Rather, jump at such an angle, the leading end and the trailing end of a pressure plate from the respective clamping channel independently, so that no manual intervention to release the leading end and trailing end from the corresponding clamping channel is required.
  • leading and the trailing end in approximately identical leg lengths, namely leg lengths between 3 mm and 12 mm.
  • the blanket plate according to the invention is defined in independent claim 9.
  • Fig. 1 shows a highly schematic of a printing plate 10 according to the invention, wherein the pressure plate 10 has a plate-like base body 11 which serves as a subject carrier or print image carrier. At opposite ends of the pressure plate 10 has over the base body 11 angled portions, namely a so-called leading end 12 and a so-called trailing end 13. About the leading end 12 and the trailing end 13, the pressure plate 10 can be clamped or placed on a form cylinder, for this purpose the forme cylinder comprises at least one clamping channel with a clamping device integrated in the respective clamping channel.
  • the leading end 12 and the trailing end 13 are angled symmetrically with respect to the main body 11, in such a way that the leading end 12 and the trailing end 13 enclose an approximately identical angle ⁇ with one side of the main body 11.
  • the angle ⁇ is between 85 ° and 90 °.
  • the angle ⁇ is about 87 °.
  • leading end 12 and trailing end 13 ensures that when a tensioned on a forme cylinder pressure plate 10 is released, the leading end 12 and the trailing end 13 each automatically jump out of a clamping channel of the forme cylinder and do not block in the same.
  • the leading end 12 and the trailing end 13 have approximately identical leg lengths.
  • the leg length of the leading end 12 and trailing end 13 is in a range between 3 mm and 12 mm. Such leg length favors the automatic jumping out of leading end 12 and trailing end 13 of a clamping channel when releasing a tensioned on a forme cylinder pressure plate.
  • a printing plate The details of a printing plate described above are analogously transferable to a blanket plate, but a blanket plate is not clamped on a forme cylinder of a printing unit but rather on a transfer cylinder of a printing unit.
  • a blanket plate bears no printed image, but rather transfers depending on the subject on the printing plate applied ink on a printing substrate to be printed.
  • a printing plate according to the invention and a blanket plate according to the invention can extend over the entire axial width of a corresponding cylinder, in which case the printing plate width or blanket plate width corresponds to the usable axial extent of the respective cylinder.
  • a plurality of pressure plates or blanket plates can also be stretched axially next to each other on a cylinder, in which case the printing plate width or blanket plate width corresponds to an integer divisor of the usable width of the respective cylinder.
  • leading end 12 and the trailing end 13 are preferably marked with at least one mark, in such a way that the leading end and the trailing end are identifiable to avoid misplacing or clamping the printing plate on a forme cylinder.
  • the or each mark may be formed as a punching or deformation, which cooperates with a corresponding contouring of the respective cylinder or an automated plate changing device and prevents swapping of leading and trailing ends when clamping the pressure plate on the cylinder.
  • the or each mark can also be formed as by exposure or by printing applied coding, wherein it is in the coding z.
  • B. may be a text, an icon or a barcode.
  • a cylinder or an automated printing plate changing device can then be associated with a reading device, by means of which the coding can be read from the printing plate, so as to prevent interchanging of the leading and trailing ends when clamping a printing plate on a cylinder.
  • the or each mark can also be designed as contactlessly readable RFID tag, wherein then the cylinder or the plate changing device is associated with a reading device for reading the RFID tag.
  • FIG. 2 and 3 each schematically show a printing unit 14 or 15 of a web-fed rotary printing press with four printing units 16, each printing unit having a forme cylinder 17 and a transfer cylinder 18 having.
  • the printing unit 14 is designed as a so-called 8-cylinder printing unit, in which transfer cylinder 18 adjacent printing units 16 roll on each other and define a printing nip through which a printing substrate 19 is moved therethrough.
  • the printing unit 15 is designed as a so-called 9-cylinder printing unit, in which all transfer cylinders 18 roll on a satellite cylinder 20 and form with the same pressure column, through which the printing substrate 19 is moved therethrough.
  • all printing plates 10 can be supplied to the respective forme cylinder 17 in the horizontal feed direction. Without the risk of a geometrical collision with cylinders of other printing units 16 so-called panoramic printing plates can be stretched in the area of the printing units shown on the right side in FIGS. 2 and 3, which differ from the printing plates shown on the left side of FIGS 10 extend over the entire circumference of a corresponding forme cylinder 17.
