Definitions

  • the invention relates to a metering meter for zone-wise metering of a color film of the type mentioned in the preamble of claim 1.
  • metering knives which consist of a resilient plate into which slots are incorporated, as can be seen from DE-A 22 28 625.
  • the slots have such a large width that they have to be filled with a soft, elastic sealing material in order to maintain a seal against the leakage of the paint.
  • the effort is relatively large, and an influence of the adjustment movement of one tongue on the adjacent, not to be adjusted tongue can not be excluded.
  • the invention has for its object to provide a meter of the type mentioned, which is simple and inexpensive to manufacture, which has sufficient tightness against the leakage of paint, without the need for additional seals, and an unrestricted adjustment of the individual zone widths Allows tongues over the entire setting range, without influencing the adjacent zone-ready tongues.
  • the width of the slots advantageously ranges from 0.01 mm to 0.03 mm. With such a width of the slot, the leakage for paints of higher viscosity is practically prevented, and nevertheless an adjustment movement of the individual zone-wide tongues is ensured without the slightest influence on their adjacent tongues. Slots with these required widths can be made in the plate, for example by laser cutting.
  • the slots In order to obtain an effective adjustment of the individual zone-wide tongues without the stress on the material or the adjustment forces to be applied being excessive, the slots have a length of approximately two thirds of the panel width, with a panel width of, for example, 8 cm.
  • the plate thickness is advantageously about one to three millimeters so that, on the one hand, the slot is not opened at maximum adjustment, but on the other hand, the required strength requirements are met.
  • the metering knife consists of a plate 1 which is screwed to the metering knife bar 2 in a known manner.
  • Each of the zone-wide tongues 3 of the plate 1 can be individually adjusted against the roller 5 via an actuator 4.
  • the gap 6, which is formed by the zone-wide tongue 3 and the roller 5, determines the thickness of the zone-wide ink film, which is delivered by the roller 5 to the inking unit, not shown, of the printing press.
  • slots 7 are made in the plate 1, which can be done, for example, by means of laser cutting.
  • the width b of the slots 7 is 0.01 mm to 0.03 mm.
  • the length 1 of the slots 7 is approximately 2 thirds of the width a of the plate 1. The slots 7 thus form the zone-wide tongues 3 of the metering knife.
  • Fig. 3 shows the adjustability of the zone-wide tongues 3 of the metering knife. From this it can also be seen that the maximum adjustment, as is the case with the zone-wide tongue 3 is shown, may be at most half the thickness d of the plate 1, so that the slots 7 are never opened and the leakage is practically excluded.
  • the metering knife practically no longer needs to be processed after the slots 7 have been introduced. Only the dosing edge is slightly ground, which underlines the simple and cheap manufacture of the dosing knife 1.
