Definitions
- An ink separation device between different color-promoting areas of ink rollers of printing machines is known e.g. B. become known from DE-PS 19 61 033.
- this ink separation device has the wax part that relatively wide ink-free areas are formed on the circumferences of the rollers. These pressure-free spaces continue through the following ink transfer rollers down to the print carrier.
- DE-OS 31 35 711 shows a flushing inking unit for a rotary printing press.
- the invention has for its object to provide an ink separation device between different ink-promoting areas of ink rollers of printing presses with a very narrow sealing surface between the ink separation device and ink roller.
- the advantages which can be achieved with the invention consist in particular in that no gaseous medium is required for sealing.
- the ink separation device can be made very thin, so that, despite the ink plate being buried in the inking roller, only negligible disturbances in the printed image are noticed when the ink separations are later shifted.
- the color division device adjusts itself automatically when worn.
- the color separation device is suitable for both oil-containing and aqueous Flexo inks and other low-viscosity printing inks. It can be used with ink rollers with a smooth as well as with a rastered surface. It is easy to replace the sheet-shaped color compartment sheets, they are also very easy and inexpensive to manufacture. Even with a high peripheral speed of the inking roller, the ink compartment plates heat up only slightly, so that special cooling of the ink compartment plates is not necessary.
- the ink division device according to the invention between different ink-promoting areas of ink rollers of printing presses is described in use in a flushing inking unit known from DE-OS 31 35 711.
- a driven anilox roller 1 is mounted in side frames (not shown).
- One or more ink application strips 2 are arranged on and off the anilox roller 1.
- An upper doctor blade 3 and a lower doctor blade 4 are attached to the ink application bars 2.
- the Ink application bar 2 is provided with a recess 7 opposite the outer surface 6 and extending over the entire length of the ink application bar 2. This Ausnenmung 7 is connected via a through hole 8 with an ink supply device.
- a guide plate 12 is screwed to a first end face 9 and a second end face 11 of each paint application bar 2.
- the guide plate 12 is provided with a guide recess 14.
- the guide recess 14 lies opposite the end faces 9 and 11 of the paint application bar 2, respectively.
- the guide recess 14 is closed at the top and bottom and dimensioned so that a thin F arbabteilblech 17 can be pushed into it and it is guided.
- the color compartment sheet 17 according to the invention is designed so that it can be easily pushed back and forth in the guide recess 14 and has a width 16 of z. B. 65 mm and a length 20 of z. B. 45 mm.
- a second end face 21 of the paint compartment plate 17 is preferably not curved.
- leaf springs 22, 23 ensure that the curved end surfaces 19 of the ink compartment plates 17 are always pressed against the outer surface 6 of the anilox roller 1.
- the ink compartment plates 17 rest on the end faces 9 of the doctor blades 3 and doctor blades 4.
- the thickness of the color compartment plates 17 can be between 0.1 mm and several millimeters thick.
- the ink compartment plate 17 is thick at an end 24 facing the anilox roller 1 over its entire width between 0.03 and 0.3 mm. If a guide part 26 of the color compartment plates 17 is thicker than the thickness 27 according to the invention of the front end 24 between 0.03 and 0.3 mm, a cut, e.g. B. be provided at a depth 18 of 3 mm, as shown in Figures 5 and 6. It is essential to the invention that the sealing surface 19 of the paint compartment plates 17 is made as narrow as possible.
