Definitions

  • the invention relates to an inking unit with at least one ink compartment wedge for an ink fountain of a rotary printing press according to the preamble of claim 1.
  • the US-PS 41 65 688 shows an inking unit for a rotary printing press and with an ink fountain with color compartment wedges.
  • the ink compartment wedges work together with a recessed ink fountain roller and with a locked inking roller.
  • the color compartment wedges each have a longitudinal groove closed at both ends, into which a number of bores open, which are connected to a compressed air source.
  • the invention has for its object to provide an inking unit with an ink compartment wedge in an ink fountain of a rotary printing press with a smooth or also detented, i.e. to provide with ink cup roller (anilox), which is steplessly displaceable along the ink fountain roller and which allows thin, jammed printing inks to be kept apart, it must be possible that the ink fountain roller rotates at a peripheral speed which is equal to the paper speed.
  • ink cup roller anilox
  • a wear-free ink compartment wedge has been created which has no contact with the surface of the ink fountain roller.
  • several colors can be arranged side by side, and it does not have to depend on the surface quality of the ink fountain roller, for. B. grid surface, be taken into account. Also, e.g. B. can be changed from a normal newspaper page width to double width (panorama print).
  • Rotary printing press one or more ink compartment wedges 2 are arranged.
  • a driven, smooth or rasterized ink fountain roller 3 rotates at a peripheral speed which is equal to the paper speed, and is mounted in side frames in a known manner.
  • An approximately 6 mm wide and 2 mm deep groove 6 is machined into the end face 4.
  • the groove 6 is closed at both ends 5, 10.
  • a plurality of bores 7, which open into the groove 6, lead through the body of the ink compartment wedge 2. Ends 8 of the holes 7 are connected via hose connections 9, hoses 11 to a compressed air source 12, not shown.
