Definitions

  • the invention relates to a process for the production of a metallic endless press belt with an embossed engraving, which is used for the production of laminates, particle boards, thermosetting and thermoplastic films and films with structured surfaces in double belt presses, in which rolled or galvanically deposited strip-shaped metal sheets by longitudinal and / or transverse welding be connected to form an endless belt and the material of the endless belt consists of a precipitation-hardenable metal alloy or one that can be changed in its crystal structure by heat treatment.
  • thermoset pressed laminates as well as plastic-coated hardboard, wood fiber board, chipboard, glass fiber board and the like.
  • the pattern is embossed with the help of embossing tools.
  • press plates are used in one-day presses, which are provided with an embossed engraving, which are mainly produced by an etching treatment of the press plates.
  • the laminates are pressed between two continuously running endless belts.
  • the press belt surface must be structured negatively in order to structure the plate surface.
  • the etching method as with the discontinuously operating machines. Since the endless belts are welded transversely or diagonally to the direction of travel, a structure that is different from the rest of the belt generally occurs at the weld seam, which allows the weld seam to emerge clearly after the etching and is thus embossed as a visible seam in the press laminate.
  • a method for installing a non-structured endless belt in presses which consists of a steel, the crystal structure of which can be changed by heat treatment.
  • This endless belt is used on presses in which the endless belt is placed around the circumference of a drum, so that the material to be pressed is pressed against the surface of the drum by the endless belt under tension.
  • the tape material is threaded into the machine and the two ends are welded with a welding wire with the same properties as the tape material. This is followed by heat treatment of the welded joint, so that tempering is achieved down to approximately the tensile strength of the remaining strip.
  • the strip material that can be heat-treated is stainless chromium steel with a high cobalt content or martensite-hardening nickel steel.
  • stainless chromium steel with a high cobalt content or martensite-hardening nickel steel are very brittle and susceptible to cracks given the high surface hardness required in continuous presses.
  • These steels are not suitable for the production of endless belts that are used in double belt presses.
  • the invention is based on the object of specifying a method in which the production of the surface structure of embossing tapes which are suitable for use in double-belt presses is simplified in such a way that an electroplated metal layer can be dispensed with.
  • a precipitation hardenable material is used as material in the manufacturing process for the embossing tape
  • Metal alloy namely a beryllium-copper alloy, a copper-cobalt-beryllium alloy or a copper-nickel-beryllium alloy is used, which after welding to an endless belt using a conventional method such as TIG, plasma, electron beam or laser welding process, is hardened to its final hardness by heat treatment, the structure above the weld seam matching that of the rest of the metal, after which the etching engraving is then introduced.
  • the procedure according to the invention has the advantage that the welding compound and the zone influenced by the welding have no structure deviating from the rest of the metal and thus have no different etching behavior compared to the embossing tape material during the etching. This means that the weld seam can no longer be imaged on the press laminate.
  • a further advantage of the invention is that a surface of the embossing tape which has been worn during operation can be reworked by etching without the fear of the weld seam then having to be feared on the laminate.
  • An alloy that is precipitation hardenable with the aid of heat treatment is selected as the strip material, namely beryllium-copper-wrought alloys and copper-nickel-beryllium alloys, which are sold, for example, by the company VAC in Hanau under the trade names BERYVAC and DURATHERM high tensile strength after curing.
  • the strip material namely beryllium-copper-wrought alloys and copper-nickel-beryllium alloys, which are sold, for example, by the company VAC in Hanau under the trade names BERYVAC and DURATHERM high tensile strength after curing.
  • VAC in Hanau under the trade names BERYVAC and DURATHERM
  • the precipitation hardening of the entire band takes place if the band was not yet fully hardened by the welding, or the area of the weld seam if the band material had already hardened before welding, with the help of a heat treatment, the temperature and duration of which is determined by the metal alloy used.
  • the etching engraving is made. Practically all known processes are suitable for this, such as, for example, photographic reproduction processes, a photosensitive layer being applied to the surface of the tape, which is then exposed and developed via a negative which represents the pattern. The remaining surfaces protect the tape from the etching attack; while the free areas are removed from the etching medium to the desired depth.
  • etch resist surfaces with pressure rollers
  • incomplete spraying or slurrying of such lacquers or similar methods which allow pattern-like coverage against the attack by etching agents or an embossed etching engraving, the strip surface being coated with a wax layer or a layer with similar properties , into which a profiled roller presses a pattern.
  • the areas in the tape surface that are exposed by the wax are attacked by an etching medium and removed to the desired depth.
  • the circumference of the embossing tape should be the same or an integral multiple of the circumference of the roller.
  • Fig. 1 shows a continuous working double belt press consisting of two endless belts
  • Fig. 2 shows one of the endless belts shown in Fig. 1 in the oblique view.
  • the double belt press 1 shown in longitudinal section in FIG. 1 has two endless belts 2, 3 driven synchronously by motors, which are tensioned by two rollers 4, 5 and run over heating plates 6. Between the heating plates 6 and the endless belts 2, 3 there are pressure cushions laterally delimited by seals 7, by means of which the reaction pressure is set. Instead of the pressure pads, support rollers can also be provided.
  • the preliminary product 8 fed to the inlet of the machine for example a wood chip cake soaked with synthetic resin, is pressed into a laminate 9 between the endless belts rotating in opposite directions.
  • the upper endless belt 2 or the lower endless belt 3 or both belts are provided with a negative etching engraving, which is embossed into the surface of the laminate during the production process and thus produces the desired positive surface structure.
  • the endless belts 2, 3 have widths between 700 and 2800 mm and thicknesses of 0.5 to 2 mm. As shown in FIG. 2, the two ends of the band are welded to one another transversely or diagonally. The weld seam 10 is ground and polished.
  • the embossing tape 2 consists of a tensile beryllium-copper alloy, which is a precipitation-hardening metal alloy.
  • the weld seam 10 has the same structure as the rest of the band due to the properties of the precipitation hardening metal alloy.
  • the negative embossing pattern 11 is worked into the surface of the embossing tape 2. All known methods described above are suitable for this. After the etching engraving and chrome plating has been completed, the endless belt 2 is ready for use in the double belt press 1.
