Definitions

  • the present invention relates to an apparatus for producing a laminated panel.
  • Laminated panels are widely used in the building and construction industry.
  • wall panels are typically made from a core of hardened gypsum having sheets of paper attached to either side thereof.
  • These gypsum panels are usually made by pouring a gypsum slurry on to a lower sheet of paper, applying an upper sheet of paper to the gypsum slurry and drying the slurry by passing the panel through a drying oven.
  • Panels are also used in forming the ceilings, such as forming false ceilings in office buildings.
  • a ceiling support structure is suspended from the full immediately above and infill panels are placed on the ceiling support structure.
  • the infill panels typically comprise a gypsum panel or a foamed cementitious panel. These panels are relatively heavy, discolour with age and have little strength or resistance to water.

  • the first container may contain the first glue component and the apparatus may further comprise a second container for holding the second glue component.
  • the apparatus may further comprise a glue mixer for mixing the first glue component and the second glue component together.
  • the first glue component and the second glue component are suitably mixed together just prior to feeding the glue to the first glue applicator and the second glue applicator.
  • the apparatus is provided with a single glue mixer which feeds mixed glue to the first glue applicator and the second glue applicator.
  • the apparatus comprises a first glue mixer which feeds mixed glue to the first glue applicator and a second glue mixer which feeds mixed glue to the second glue update.
  • the first glue component is applied to the sheet of material and the second glue component is applied to the sheet of material, with the first and second glue component being mixed together on the sheet of material.
  • the first glue applicator may comprise a first component applicator for applying the first glue component to the sheet of material and a second component applicator for applying the second glue component to the sheet of material.
  • glue applicator may also comprise a similar arrangement. This is a desirable embodiment as the glue components mix externally of the glue applicators, thereby minimising or avoiding the risk of premature setting of the mixed glue in the glue applicators.
  • first glue component in the second glue component are mixed together in the first glue applicator and the second glue applicator.
  • the first glue component and the second glue component are suitably selected such that, when mixed, the mixed glue rapidly sets to ensure that the mixed glue sets shortly after it has been applied to the first sheet of material and the second sheet of material.

  • the skilled person would understand that there are a number of two component glues that can be selected for use in producing the panels, with the main requirements being that the two component glue sets quickly once mixed and that the two component glue is compatible for adhering the sheets of material to the panel of material.
  • the glue may be a filler glue in that it may fill any imperfections in the materials to which it is applied.
  • the glue may comprise a single component glue, such as a hot melt glue that is applied to the sheet of material.

  • the molten or liquid glue may be supplied to the inside of a porous roller such that the glue moves through the roller and onto the sheet of material travelling past the roller.
  • a hot melt glue may also be applied to the sheet of material using an applicator tube or applicator bar, as described above.
  • the apparatus also comprises pressure applying means for applying pressure to the sheet of material once the group has been applied thereto.
  • the pressure applying means maintains good contact between the sheets of material and a panel of material whilst the glue sets. This assists in ensuring that solid adhesion between the sheets of material and the panel of material is obtained.
  • the pressure applying means may comprise one set of rollers or a plurality of rollers or one or more pressure plates. Once the laminated material passes through the pressure applying means, the laminated material is cut to a desired length. Any suitable apparatus known to be capable of cutting a moving web of material may be used in the present invention.
  • the cutting means comprises a rotatable cutter wheel which may move transversely to the laminated material.

  • the cutter may be mounted on biasing means, such as a spring, such that when the cutter contacts the panel the movement of the panel causes the cutter to move along with the panel. When the cutter is disengaged from the panel, the biasing means moves the cutter back to a cutter starting position.
  • the cutter may be mounted to a drive means (such as a motor or a random) that moves the cutter along with the panel during cutting.

  • the sheets of paper are unrolled from paper rolls 34, 38.
  • the glue applied to the panels dries very quickly and, in practice, it dries in a matter of seconds. Therefore, by the time the laminated panels have left the main press section 22, the glue has dried. In order to complete the panels, they pass through an edge trimming section 21, where the panels are trimmed to the required width (the edge trimmers may be of conventional technology) and a cutting section 24, where the laminated panels are cut to the desired length. The cut panels then become stacked on accumulation table 26. The stacks of panels are then passed to side transfer conveyors 28 (see figure 2), where the stacks of panels are prepared for transport. In this regard, the stacks of panels may be bound with tape or other bindings, or wrapped in a shrinkwrap plastic.
