Definitions

  • the invention relates to a printing machine cylinder according to the preamble of claim 1.
  • a printing machine cylinder comprises at least one extending in the axial direction of the printing press cylinder channel, and wherein in the or each clamping channel in each case at least one clamping device is received to on a lateral surface of the Press cylinder at least one mold.
  • the or each on the press cylinder to exciting form has a leading end and a trailing end, wherein the leading end and the trailing end are each clamped by a clamping part of a clamping device in the respective clamping channel between the respective clamping part and a channel wall of the respective clamping channel.
  • the leading end is to be stretched between the clamping part and a leading channel wall of the respective clamping channel and the trailing end between the clamping part and a trailing channel wall of the respective clamping channel, where it is difficult in known from practice press cylinders, the leading end always between the clamping part and the leading Channel wall of the respective clamping channel and the trailing end to clamp between the clamping part and the trailing channel wall of the respective clamping channel. Rather, in known from practice printing machines when clamping a mold, the leading end between the clamping part and a trailing channel wall and the trailing end between the clamping part and a leading channel wall reach, in which case no proper clamping of the exciting shape is possible.
  • insertion tools are used in printing press cylinders known from practice, which ensure that the leading end of an exciting printing form between the clamping part and the leading channel wall of the respective clamping channel and the trailing end between the clamping part and the trailing channel wall the respective clamping channel is clamped.
  • a printing machine cylinder in which this can be ensured without the aid of special insertion aids.
  • the present invention has the object to provide a novel printing press cylinder.
  • the clamping part of each clamping device seen in the axial direction a plurality of insertion bevels, namely first Ein Scienceschrägen for the leading end of an exciting form and second Ein Switzerlandschrägen for the trailing end of an exciting form, seen in the axial direction alternately in succession or juxtaposed
  • the leading end of a to exciting shape and the trailing end of a too exciting form to form projections and recesses are contoured such that the projections of the leading end of an exciting shape with the first insertion bevels of a clamping member and the projections of the trailing end of an exciting form with the second insertion bevels of a clamping member cooperate such that the leading end of a too exciting form between the clamping part and a leading channel wall of the clamping channel and the trailing end of an exciting form between the clamping part and a trailing Kan Alwand the clamping channel is self-centering tensioned.
  • Fig. 1 shows a schematic section of a formed as a forme cylinder 10, according to the invention press cylinder in the region of a clamping channel 11 which extends in the axial direction of the printing press cylinder 10.
  • a clamping device 12 is added, by means of which a leading end and a trailing end of at least one pressure plate in the clamping channel 11 can be clamped.
  • the in Fig. 1 illustrated cylinder 10 comprises two 180 ° mutually offset clamping channels 11 with corresponding clamping devices 12, so seen in the circumferential direction on the forme cylinder 12, two printing plates can be stretched one behind the other.
  • the clamping device 12 of the clamping channel 11 is used for clamping adjacent ends of two different printing plates, namely the tensioning of a leading end 13 of a first printing form 14 and the tensioning of a trailing end 15 of a second printing form 16.
  • the respective other ends of these two printing plates 14, 16 are on the in Fig. 1 not shown, in the clamping channel 11 opposite clamping channel positioned clamping device clamped.
  • the accommodated in clamping channel 11 clamping device 12 has a clamping member 17, which is pressed by a spring member 18 in the radial direction of the forme cylinder 10 to the outside to ultimately clamp the leading end 13 of the printing plate 14 and the trailing end 15 of the printing plate 16 in the clamping channel 12.
  • a clamping member 17 which is pressed by a spring member 18 in the radial direction of the forme cylinder 10 to the outside to ultimately clamp the leading end 13 of the printing plate 14 and the trailing end 15 of the printing plate 16 in the clamping channel 12.
  • Fig. 1 shows, the leading end 13 of the printing plate 14 between the clamping member 17 and a leading channel wall 19 of the clamping channel 11 stretched, whereas the trailing end 15 of the printing plate 16 between the clamping member 17 and a trailing channel wall 20 of the clamping channel 11 is stretched.
  • Fig. 2 shows a schematic perspective view of the printing plate 14 in the region of the leading end 13 and trailing end 15 thereof, wherein, as Fig. 2 can be removed, the leading end 13 and the trailing end 15 of the printing forme 14 at two diametrically opposed clamping members 17 which are positioned in diametrically opposed clamping channels are clamped.
  • Each clamping part 17 has according to Fig. 2 seen in the axial direction over a plurality of chamfers, namely on first chamfers 21 for the leading end 13 of a printing plate 14 and second chamfers 22 for the trailing end 15 of a printing plate 14.
  • the different chamfers 21, 22 are seen in the axial direction alternately in succession or juxtaposed, with between each two first insertion bevels 21 each have a second insertion bevel 22 is positioned.
  • the leading end 13 of a too exciting printing plate 14 is contoured so as to form projections 23 and recesses 24, that the projections 23 of the leading end 13 of a compressible printing plate 14 with the first insertion bevels 21 of the clamping member 17 cooperate.
  • the trailing end 15 of a pressure plate 14 to be clamped to form projections 25 and recesses 26 is contoured such that the projections 25 of the trailing end 15 with the second insertion bevels 22 of the respective clamping member 17 cooperate.
  • the cooperating with the projections 23 of the leading end 13 first insertion bevels 17 of the clamping members 17 and cooperating with the projections 25 of the trailing end 15 second insertion bevels 22 of the clamping members 17 each form capture areas for the leading end 13 and trailing end 15 to be clamped printing form 14, so the leading end 13 of the exciting pressure form 14 between the clamping member 17 and a leading channel wall of the respective clamping channel and the trailing end 15 of an exciting pressure mold 14 between the clamping member 17 and a trailing channel wall of the respective clamping channel is self-centering tensioned without insertion aids must be used.
  • the contouring of the clamping parts 17 and the leading ends 13 and trailing ends 15 to exciting printing forms automatically or automatically causes the centering of the clamping plates in the clamping channel, so therefore a leading end 13 to be clamped printing plate between each of the clamping part and the corresponding leading channel wall and the trailing end of the same between the clamping part and the corresponding trailing channel wall is tensioned.
  • the axial width of the first insertion bevels 21 of the clamping parts 17 is adapted to the axial width of the projections 23 of the leading end 13 of the respective clamping part to exciting printing form.
  • the axial width of the second insertion bevels 22 of the clamping parts 17 is adapted to the axial width of the projections 25 of the trailing end 15 of the respective clamping part to exciting printing form.
  • Fig. 1 can be seen that seen in the axial projection, the alternately successively or juxtaposed positioned first Ein thoroughlyschrägen 21 and second Ein thoroughlyschrägen 22 of a clamping member 17 form a centering 27, on which a tool can be applied to the clamping member 17 against the spring element 18 provided Spring force to release a printing plate tension on the forme cylinder 10 to press down.
