  • the mechanical properties are more relevant the materials of the elastic layer, so according to the preferred embodiment of the hose, which is not involved even in the process of receiving and dispensing of paint and / or paint, so far as the choice of materials is not limited.
  • a substrate 10 is conveyed from left to right.
  • the substrate 10 is, for example, a board of wood-based material or a plastic board of e.g. ABS or PVC.
  • the substrate 10 may be an article having a more or less complicated three-dimensional profile, such as a part of a window frame or the like. In the figures, the profile is not shown in detail for the sake of simplicity.
  • the promotion of the substrate 10 is carried out with a conveyor belt 12 which is driven by rollers 14.
  • the direction of transport corresponds to that indicated by the direction of rotation indicated by the arrows.
  • a basecoat which for example can be slightly colored, can be applied to the substrate in the transport path of the substrate (ie to the left of FIG. 1), in particular by spraying or rolling or the like.
  • a base coat is also a metallic paint into consideration. This preparation the substrate before its promotion in the first order station according to Figure 1 is not shown in the figures.
  • the application station according to FIG. 1 has a gravure printing roller 16, which is shown in section, for example, in FIGS. 4 and 5.
  • the pressure roller 16 has a surface 20.
  • the pressure roller 16 cooperates with a gravure cylinder 18.
  • Recesses are formed in the surface of the engraving cylinder 18, which correspond to the printed image to be produced on the substrate 10, that is to say recesses corresponding to a natural wood grain or also corresponding to a natural stone image, such as marble or granite.
  • the directions of rotation of the engraving cylinder 18 and the pressure roller 16 are indicated by arrows.
  • doctoring devices 22, 24 keep the surfaces of the cylinder or the roller clean, so that the ink appears only at the desired locations.
  • the substrate 10 moves in the direction of rotation of the pressure roller 16 with this in abutment, so that the printed image is transferred from the surface 20 of the pressure roller 16 to the substrate 10.
  • a second application station In the transport of the substrate 10 is a second application station according to Figure 2 with a paint applicator roll 26 and a paint metering roller 28.
  • a paint 32 is applied to the printed surface 30 of the substrate 10.
  • the directions of rotation of the rollers are again indicated by arrows.
  • the rollers will turn of doctor devices 34, 36 acted upon. Details of the roller 26 are described below with reference to Figures 4 and 5 in more detail.
  • the substrate 10 printed in the first application station according to FIG. 1 and painted in the second application station according to FIG. 2 is conveyed by the conveyor belt 36 to a third application station according to FIG. There, a further lacquer layer is applied to the printed and lacquered surface 40 of the substrate 10 by means of a conveyor belt 42, which is driven by rollers 44, and a pore pressure roller 46, which cooperates with a gravure cylinder 48.
  • a conveyor belt 42 which is driven by rollers 44, and a pore pressure roller 46, which cooperates with a gravure cylinder 48.
  • the directions of rotation of the rotating components are again marked with arrows. Details of the roller 26 are described below with reference to Figures 4 and 5 in more detail.
  • a gravure cylinder 48 which carries projections which correspond to the pores ultimately to be printed on the substrate 10.
  • the pore-pressure roller 46 is provided with a lacquer layer intentionally has small holes ("missing dots"), whose distribution corresponds exactly to the desired pore image of the reproduced wood surface. Doctor devices 50, 52 cooperate with the rollers.
  • FIGS. 4 and 5 schematically show exemplary embodiments of the pressure rollers 16, 26, 46 used above.
  • the roller 16 has a hard roller core 60 of, for example, metal, which is rotatable in a conventional manner about an axis of rotation.
  • FIG. 4 shows a radial section and FIG. 5 shows an axial section through the roller 16.
  • Each hose 62 has an inner hose wall 64 and an outer hose wall 66.
  • the inner hose wall 64 abuts the surface 70 of the roll core 60.
  • the outer hose wall 66 is important for the printing process. It supports radially inside an outer shell 68, which causes the printing process.
  • the sheath 68 extends across the entire width of the roller 16 between two end flanges 72, 74 which position both the hoses and the sheath.
  • a fluid for example a gas or a liquid
  • each of the hoses 62a, 62b, 62c, 62d may be selectively actuated via valves (not shown), and thus the pressure in each of the hoses may be adjusted individually, independently of the other hoses, such that the pressure with which the respective one of the hoses 62a, 62b, 62c, 62d
  • Hose sleeve 68 is supported, can be adapted to the respective profile of the object to be printed.
  • the shell 68 can specifically adapt to the profile of the object.
  • the outer shell 68 a material of greater hardness is chosen than for the tube 62.
  • the material of the outer shell 68 has a hardness greater than 40 Shore.
  • An advantage of the rollers described is that the outer shell 68 is easily replaceable when worn.
  • a softer material is chosen as the sheath 68, for example a silicone rubber having a thickness of 1 to 3 mm.
  • a hard rubber is suitable for the outer shell 68.
  • the embodiment described above may, in a simpler embodiment, be modified such that all hoses 62a, 62b, 62c, 62d are conductively connected so that the fluid pressure in them is equal.
  • the means (valves, lines) to adjust the pressure in the hoses are not shown in detail in FIG.
  • the conduits may pass through the roller core 60 and from there to the individual hoses.
  • the conduits may also extend in the space between the outer surface 70 of the roller core 60 and the sheath 68.
  • FIGS. 6 and 7 show exemplary embodiments of how a hose or several tubes can be supplied with fluid.
  • a single tube 62 is provided, which is supplied with fluid via a fluid line 76 which is formed in the roller core 60. Via a rotary seal, the fluid supply can also be carried out during operation, so that in particular the fluid pressure can be permanently monitored.
  • Figure 7 shows an embodiment with five hoses 62a, 62b, ...., 62e, which can be pressurized via fluid lines 78 either with fluid pressure, so that in each hose individually either a desired pressure is adjustable.
  • the fluid lines can be connected via a rotary seal in each case with a central fluid supply.
  • the lines run in an axial cavity 80 of the roller core 60, which is sealed by a plug 82.
  • the fluid lines 78 can be provided with the desired fluid pressure before the beginning of the printing process at standstill of the roller, whereupon then the lines are closed and the roller takes up the operation. No rotary seals are required. However, if the fluid pressure during operation is continuously monitored and adjusted if necessary, rotary seals for the leads 78 are required, which are known as such in mechanical engineering (hydraulics).
  • rollers described can be used not only in a printing arrangement according to Figures 1 to 3, but in general when transferring paint and / or paint on an object.
