Definitions

  • the invention relates to a method for treating the surfaces of printing substrates in Printing machines.
  • the device for carrying out the method consists of a blown air supply duct, a suction air duct and / or a brush.
  • Printing machines also process substrates that are difficult to coat exhibit. These are in particular films made of plastic or coated with polyethylene Materials. Dusting substrates also cause problems with printing.
  • the components brushed off are suctioned off or one subjected to chemical treatment. That means, the detached particles are with a Washed off cleaning liquid containing detergent additives.
  • a device for removing the dust has become known from EP 0 520 145 A1. It is used to remove the bond between the dust and the substrate Discharge electrode used. The dust is then removed via appropriately dimensioned suction channels dissipated.
  • the object of the invention is a method and a device for implementation to develop this process by which the wettability of the surface these problematic substrates are increased with little effort.
  • the advantage of the solution according to the invention is that the intensity of the mechanical treatment can be reduced, which then saves overall leads to energy. Detergents with additives are unnecessary, so that an environmentally friendly Aspect.
  • the invention will be explained in more detail below using an exemplary embodiment.
  • the associated figure shows the device according to the invention in a schematic representation.
  • the printing material 1 guided on a printing cylinder 2 a combination bar 3 assigned.
  • the arrangement of the combination bar 3 advantageously takes place before the first pressure zone.
  • the combination bar 3 consists of a frame of the printing press, not shown arranged traverse 31, on which a corona electrode 33 is arranged.
  • the energy supply and the generator for operating the corona electrode 33 are not in the figure shown.
  • the traverse 31 is a blown air supply duct 34 and one via a holder 321 Brush 32 assigned.
  • the brush 32 is both alone and in combination with the Blown air supply duct 34 is conceivable.
  • the arrangement of the blown air supply channel 34 is also alone possible.
  • Both the blown air supply duct 34 and the brush 32 are in the direction of the Seen direction of movement of printing material 1 (see arrow) downstream of the corona electrode 33.
  • a suction air duct 35 is arranged upstream of the corona electrode 33.
  • the printing material 1 is passed through the printing cylinder 2 into the area of the corona electrode 33 guided.
  • the surface of the substrate 1 is bombarded with electrons. This have the effect that the long molecular chains of the plastic are broken and thus a large number of open valences is generated.
  • the free valences are subordinate other C-OH groups, which increases the surface energy and the wetting ability the surface rises considerably.
  • the following brush 32 (seen in the direction of movement of the printing material 1) loose particles, such as abrasion or dust particles, mechanically from the surface separated and by the air flowing in the direction of the arrows via the suction air duct 35 the area of the combi bar 3 dissipated. Through the suction air duct 35, the During the corona discharge, harmful ozone released and extracted from the area of Operator removed.
