Definitions

  • the invention relates to a method and a device for the continuous production of surface-structured sheet webs and chipboard produced therewith, as well as an endless press belt for carrying out the method and a belt press equipped with such an endless press belt.
  • a separate embossing tape is to be inserted between the two endless press belts of a double belt press.
  • the surface structuring of the embossing tape can be produced by grinding, sandblasting, shot peening, thermal spraying of a metal alloy, molding a profiled roller or drum under pressure, etching, multi-stage etching and the like.
  • embossing tape means an increased outlay in terms of device and process technology. Furthermore, the surface structures that can be achieved with the known embossing tape on a particle board covered with a synthetic resin-impregnated paper web are not suitable for applying the fine structuring required to avoid a gloss or a surface smoothness that is too great, without also producing deeper impressions and other irregularities.
  • the aim of the invention is, in particular, to provide a particularly economical method which ensures universal surface structuring and a particularly varied degree of refinement of plate surfaces and which makes it possible to keep the mechanical and operational expenditure low.
  • the type of embossing of the endless belts according to the invention, which can take place on the belt press itself, is particularly advantageous.
  • the belt press thus simultaneously serves as part of the device for producing the endless belts. It is also advantageous that worn press surfaces of an endless press belt can be reworked at any time due to prolonged use.
  • the use of the belt press itself as part of the device for producing the surface structuring therefore has an advantageous effect not only in the first production of the press belt, but also in post-processing, for which the glass ball blasting device only has to be arranged again in the region of one of the deflecting rollers, while the endless belts do not have to be disassembled or specially prepared in any way.
  • Discontinuous process steps can follow the surface structuring which takes place continuously by means of the endless press belts, as a result of which a considerable increase in economy and a degree of refinement of plate surfaces can be achieved, which meets the highest demands.
  • Figure 1 shows in a highly schematic form a double belt press 16 with two endless press belts 13, 14, which are placed around deflecting rollers 19, 20 and form a press nip 15 with two debris located opposite one another at a short distance.
  • the two pressing and heating devices acting on the press nip 15 defining debris are indicated at 25, 26.
  • a fleece 12 composed of lignocellulosic and / or cellulose-containing chips or fibers is fed into the press nip 15 of such a double belt press 16, which is formed and pressed into a chipboard web 11 in the double belt press 16.
  • a synthetic resin-impregnated paper web 17 is introduced into the press nip 15, which is unwound from a suitably arranged supply roll 27.
  • the pressing surface 18 of the upper endless pressing belt 13 according to FIGS. 1, 2 and 3 is made by means of a glass ball blasting device 21 with a surface structure of a roughness depth of less than 100 ⁇ m.
  • the glass ball blasting device 21 is arranged above the upper left deflection roller 19 and has a ball jet nozzle 28 which is arranged directly above the pressing surface 18.
  • the ball jet nozzle 28 is sealed off from the surroundings by circular brushes 29 or the like which rest on the pressing surface 18.
  • glass balls 24 with a diameter of approximately 0.2 mm are conveyed within an air jet with a pressure of 3 bar to 5 bar into the nozzle 28, from where they reach the pressing surface at high speed 18 meet within the all-round seal formed by the brushes 29 and provide a characteristic fine surface structure there. Due to the high speed and the special jumping behavior of glass balls on a stainless steel surface, the glass balls snap back after hitting the pressing surface 18 and are sucked off by a suction pipe 31 provided on the side of the nozzle 28 and returned to the glass ball blasting device 21. The glass balls can be reused there.
  • the ball jet nozzle 28 has a circular cross section and is first placed in the area of one edge of the endless press belt 13, as is indicated in FIG. 3. Subsequently, the endless press belt 13 is then slowly rotated in the direction of the arrow p in FIG. 1, whereupon the glass ball blasting device 21 is put into operation. In this way, a strip 22 (FIG. 3) running around the endless press belt 13 is gradually structured in the desired manner.
  • the shot-peening nozzle 28 is displaced laterally approximately by its diameter in the direction of the arrow 32 in FIG. 3, whereupon an adjacent strip 23 is then shot-peened in a corresponding manner.
  • the pressing surface of the lower endless press belt 14 could also be structured on the surface, the ball jet nozzle 28 in the region of the deflecting roller 19 or 20 being placed somewhat obliquely from above onto the pressing surface.
  • the press belts initially supplied by a manufacturer are formed by laying around the deflecting rollers 19, 20 and welding their free ends together to form the endless press belts 13, 14.
  • the production is then continued by applying the surface structuring by means of the glass ball radiation.
  • the glass ball blasting device 21 After completion of the surface structuring on one or both pressing surfaces 18, the glass ball blasting device 21 is removed and the chipboard manufacturing process described at the beginning can now be started.
  • FIG. 4 shows a chipboard 11 according to the invention, which consists of a central part 33 made of wood shavings or wood fibers held together by a binder and is covered on both sides with a paper web 34 impregnated with synthetic resin.
  • a surface structuring 35 is present in the surface of the paper webs 34, which has been produced by the glass-ball-blasted pressing surfaces 18 of the belt press 16 according to FIG. 1 and has a characteristic formation due to the glass-ball radiation, which is a very fine and uniform fine matting or roughness can be described.
