Definitions

  • the invention relates to a web-fed printing machine, in particular an illustration printing machine, according to the preamble of claim 1 or 6 or 9.
  • a printing unit of an offset web press in addition to a forme cylinder, an inking unit and optionally a dampening unit further comprises a transfer cylinder, with the aid of the transfer cylinder ink can be transferred to a printing material to be printed.
  • the transmission cylinder is assigned a transmission system.
  • the form cylinder is assigned a printing plate system.
  • the invention relates to a web-fed printing press with transmission systems designed as rubber sleeve systems and / or to printing-plate systems designed as form-sleeve systems. Rubber sleeves are pushed onto a transfer cylinder in the axial direction and form sleeves are pushed onto a forme cylinder in the axial direction and therefore do not require any tension channels on the respective cylinder, which then enables rapport-free printing.
  • the transmission cylinder associated with the transmission system and / or the form cylinder associated pressure molding system in the axial direction of the respective cylinder in such a multi-part form that the transmission system has a plurality of axially positioned on the transfer cylinder rubber sleeves and / or the printing plate system having a plurality of axially positioned on the form cylinder Formsleeves ,
  • the transfer cylinder has at least two independent pressurized air systems and / or the forme cylinder has at least two independent pressurized air systems to assemble and disassemble the sleeves on the respective cylinder.
  • the present invention has the object to provide a novel web printing press.
  • the transfer cylinder has at least three independent compressed air systems and / or the forme cylinder at least three independent compressed air systems in order to mount the sleeves, namely the rubber sleeves and / or the printing form sleeves, on the respective cylinder, namely on the transfer cylinder and / or the forme cylinder to dismantle.
  • the first aspect of the invention as well as the second aspect and the third aspect of the invention can be used either alone or in combination of two aspects or even in combination of all three aspects with one another on a web press.
  • Fig. 1 and 2 show a transfer cylinder 10 of a printing unit of a web press according to the invention, in particular an illustration printing machine, wherein the transfer cylinder 10 is associated with a transmission system 11 which is disposed on an outer surface 12 of the transfer cylinder 10 and pushed onto this outer surface 12.
  • the rubber sleeve 13 is one of a Monatageseite 15 of the transfer cylinder 10 facing and therefore montageseiteiteitigen rubber sleeve and the rubber sleeve 14 is a stop side 16 of the Transfer cylinder 10 facing and therefore stop side rubber sleeve.
  • Fig. 1 shows the transfer cylinder 10 in a state in which both rubber sleeves 13, 14 are pushed onto the outer surface 12 thereof.
  • Fig. 2 on the other hand shows the transfer cylinder 10 exclusively together with the stop rubber side sleeve 14, namely when pulling or pulling it from the surface 12 of the transfer cylinder 10 in the direction of the double arrow 17th
  • Fig. 1 shown transmission system 11 is divided so that a joint 18 between the directly juxtaposed rubber sleeves 13, 14 in the middle of the printing-used width L of the transfer cylinder 10 and the transmission system 11 is located.
  • Each rubber sleeve 13, 14 thus has a printing width of 1 ⁇ 2 L.
  • the transmission system 11 of Fig. 1 is therefore seen in the axial direction of the transfer cylinder 10 is divided symmetrically.
  • the joint 18 between the two rubber sleeves 13, 14, which are positioned next to each other on the transfer cylinder 10 in the axial direction, is located at a non-printing location or a non-printing axial position of the transfer cylinder 10, in particular at an axial position of a longitudinal fold to be formed on the printed substrate and / or longitudinal section.
  • the transmission system 11 is made in two parts, it should be noted that the same in the axial direction of the transfer cylinder can be formed more than two parts.
  • each of the compressed air systems 19, 20 and 21 has in each case at least one air opening 22, 23 or 24, via which the respective compressed air system opens on the outer surface 12 of the transfer cylinder 10.
  • an air pressure p can be provided independently in each case in order to assemble and disassemble or remove the rubber sleeves 13, 14 between the surface 12 of the transfer cylinder 10 and the respective rubber sleeve 13, 14 a Build up air cushion.
  • the rubber sleeve 13 seals in the region of the mounting side 15 against air leakage from, so that an air cushion over the entire axial Length of the rubber sleeve 13 can be constructed by means of the compressed air system 19.
  • the relatively small distance A between the air openings 22 of the first compressed air system 19 and the mounting side end of the mounting side rubber sleeves 13 is typically in the order of between 5 millimeters and 10 millimeters.
  • the distance B is on the order of 20 millimeters to 30 millimeters. In this way it can be achieved that the mounting side end of the rubber sleeve 14 seals to the surface 12 of the transfer cylinder 10, whereby leakage losses avoided and also on the rubber sleeve 14, an air cushion can be safely constructed.
  • the transfer cylinder 10 In the transfer cylinder 10, whose transmission system 11 is divided symmetrically in the axial direction of the transfer cylinder 10 and whose air openings 22, 23 of the compressed air systems 19, 20 have a different distance from the mounting side ends of the corresponding rubber sleeves 13, 14, yet a safe mounting and removing the rubber sleeves 13, 14 to ensure the surface 12 of the transfer cylinder 10 is in the embodiment of Fig. 1 in addition to the first compressed air system 19 and the second compressed air system 20, the third compressed air system 21 is present.
  • the air openings 24 of the compressed air system 21 are preferably located in the axial center between the air openings 22, 23 of the compressed air systems 19, 20.
  • the or each air opening 24 of the third compressed air system 21 opens between the air openings 22, 23 of the compressed air systems 19, 20 on the surface 12 of the transfer cylinder 10. Since in the embodiment 1 ⁇ 2L ⁇ 1 ⁇ 2L + BA, can be ensured with the third compressed air system 21, that in each position of a rubber sleeve 13 on the transfer cylinder 10, the same at least one air opening 22 or 23 or 24 covers at least one of the compressed air systems 19 and 20 and 21 respectively. On the surface of the transfer cylinder 10 opening air holes 22, 23, 24 of the three compressed air systems 19, 20, 21 are spaced apart such that the axial distance of the air holes 22, 23, 24 is smaller than as the axial extent of the rubber sleeves.
  • the rubber sleeves 13, 14 thus have the same axial extent of each 1 ⁇ 2 L on.
  • the transmission system of the transfer cylinder has an asymmetrical division ratio, so that the rubber sleeves have different axial extents.
  • the Kunststoffsleeves 13, 14 have different axial dimensions, preferably the stop side rubber sleeve 14 has a greater axial extent than the mounting side rubber sleeve 13th In this case, can then be dispensed with the third compressed air system 21, since then it can be ensured that each of the rubber sleeves 13, 14 in each position one of the air openings 22, 23 of the compressed air systems 19, 20 covers.
  • the inventive concept is not limited to transfer cylinders and transmission systems, but the invention can also be used in the form of cylinders and printing forme systems.
  • the above explanations apply analogously to printing plate systems designed in several parts in the axial direction of a forme cylinder, in which case the printing plate systems preferably comprise a plurality of form sleeves positioned next to one another in the axial direction.
