Definitions

  • the invention relates to an endless belt with a metal band body and an inner band side and an outer band side, wherein the band outer side has three-dimensional embossed structures in the form of valleys and ribs.
  • the invention relates to a device for producing decorative panels, wherein the apparatus comprises a double-belt press with at least two endless belts, of which at least one is designed as a press belt with embossed structures.
  • Press belts of the above type are usually used for the production of decorative panels, which in addition to an image also have a three-dimensional image-corresponding surface structure, in order to achieve a desired optical or haptic impression.
  • endless belts of the type mentioned above are used.
  • grains or pores of the wood surface are primarily represented by the three-dimensional embossed structures.
  • a carrier material provided with an image of a wood surface and impregnated is usually applied to a carrier plate and the corresponding three-dimensional structure is embossed by means of a press belt.
  • a method is for example from the AT 500 312 B1 known.
  • a relevant press belt or a method of manufacturing such a press belt is also known from the document EP1395443B1 known.
  • a disadvantage of the known press belts is that they have a constant degree of gloss over the entire surface, which has an unfavorable effect on achieving a depth effect in the patterns shown.
  • the decorative surfaces of decorative panels made with conventional press belts therefore give a two-dimensional impression despite the presence of three-dimensional structures.
  • a press belt of the aforementioned type according to the invention that the outside of the band in at least a first at least one valley and / or at least one rib region comprising a different gloss level than in at least a second at least one valley and / or at least one rib Has area.
  • the different gloss levels of the areas can be achieved by different roughness depths in the surface of the press belt.
  • the areas of different roughness depths are then transferred to the decorative surface and there also areas of different gloss levels result.
  • areas which are intended to convey a three-dimensional impression may be matted and have a lower degree of gloss than other areas of the decorative surface.
  • the at least one first area comprises a plurality of valleys and ribs, wherein a surface of the band outside in the at least one first area has a uniform gloss level.
  • the at least one second region comprises a plurality of valleys and ribs, wherein a surface of the band outside in the at least one second region has a uniform degree of gloss.
  • the at least a first region of a valley and the at least one second region is formed from a rib, wherein a bottom of the valley of the at least one first Area has a smaller roughness than a crest of the rib of the at least one second area.
  • the press belt has a different coating from a base material of the belt body coating, in particular a coating of chromium, through which in particular the ridges of the ribs are formed.
  • At least sections of the at least one first region and the at least one second region can also be arranged next to one another viewed in a transverse direction of the endless belt.
  • the ribs and valleys of the first region can be oriented in the same direction, preferably parallel to one another, the ribs and valleys of the second region at least partially not being in the same direction as the ribs and valleys of the first region, the second region has a lower gloss level than the first area.
  • the above object can also be achieved with a device of the type mentioned in the present invention in that the press belt is formed as a press belt according to one of claims 1 to 8.
  • a device for producing decorative panels for example laminates with wooden decorative surfaces or decorative tiles with a stone decor surface, can have a double-belt press 1.
  • carrier plates 3 On a lower belt 2 are here carrier plates 3, on which a impregnated with resin or similar paper 4, which carries a picture print arranged.
  • the precut paper 4 is placed on the support plates 3.
  • the paper 4 substantially completely covers the surface of the carrier plates 3 serving as a support surface on the carrier plates 3.
  • a press belt 5 which has embossed structures 6, which are pressed into the resin-impregnated paper 4 in order to obtain a corresponding three-dimensional surface structure in the decorative plate.
  • the embossed structures 6 of the press belt 5 can be spaced from one another by surface sections 7 referred to below as "gaps".
  • the gaps may have an intermediate structure that is different from the embossed structures 6 and that has a "neutral pattern" such as simple geometric structures such as straight parallel lines, grids, etc.
  • the intermediate structure is particularly preferably a pattern which has a high similarity with the basic pattern, but in contrast to this does not contain any prominent sites such as knotholes.
  • the press belt 5 has a belt inside 9 and a belt outside 10.
  • the embossed structures 6 are in this case arranged on the outside of the tape 9, wherein the tape outer side 9 has at least two regions 15 and 16 which have a different degree of gloss.
  • a plurality of regions 15 and 16 are provided. Alternating in the longitudinal direction of the tape.
  • the regions can also be arranged side by side in the transverse direction of the press belt 5, so the regions 15, 16 could be arranged, for example, like a checkerboard or any other order.
  • the press belt 5 a band body 8 made of metal.
  • the press belt 5 may optionally have a coating different from a base material of the belt body 8, for example a coating of chromium.
  • the embossed structures 6 in the form of valleys 11 and ribs 12 are formed.
  • Each of the regions 15 and 16 in this case comprises at least one valley and / or one rib.
  • both the first region 15 and the second region 16 comprise a plurality of valleys 11 and ribs 12, as shown in FIG Fig. 4 is shown.
  • the gloss level of the first region 15 and the second region 16 is different from each other in all embodiments. Within areas 15 and 16, the gloss level can be constant and uniform throughout the entire area.
  • the first region 15 is formed by a valley 11 and the second region 16 is formed by a rib, then a bottom of the valley 11 can have a smaller roughness depth than a crest of the rib 14 of the at least one second region 16.
  • the comb of the Rib 14 may be provided with a layer, for example a chromium layer.
  • the ribs 12 and the valleys 11 of the first region 15 in the same direction to each other, preferably parallel to each other, be oriented.
  • the ribs 14 and valleys 13 of the second region 16 can at least partially not run in the same direction to the ribs 12 and valleys 11 of the first region 15.
  • the second region 16 corresponds to a knothole and the first region 15 corresponds to a grain of a log.
  • the second region 16 corresponding to a knothole has a lower degree of gloss than the first region 15.
  • a mask-shaped coating can be applied to it, for example, wherein structuring of the belt surface is achieved in non-coated regions of the press belt 5 in a further process step, for example by etching or other removal or application of material.
  • a further step which may, however, also take place before a material removal or application, for example the surface can be partially irradiated with particles (eg sand, steel particles, ceramic particles, etc.) in order to achieve different degrees of gloss in the areas 15, 16 ,
  • particles eg sand, steel particles, ceramic particles, etc.
  • the areas 15 and 16 consist only of a single valley or a single rib, then a different roughness can be achieved, for example, that after a removal of material by etching the entire band outside 10 of the press belt 5 at a very shallow angle, for example Almost parallel to the surface of the band outside 10, is irradiated with a particle beam, since in this case the ribs 12, 14 are roughened more than the valleys 11, 13.
  • the production of the press belt 5 according to the invention also can be done in other ways than those described above.
  • the press belt 5 can in principle be effected by means of all suitable chemical, electrochemical, mechanical types of material removal or application.
