Definitions

  • the present invention relates to a method according to the preamble of claim 1.
  • the present invention further relates to a production device according to the preamble of claim 5.
  • Laminate is a laminate which is formed by pressing, gluing and / or gluing at least two layers of the same and / or different material.
  • a laminate which can be used, for example, as a floor, as a wall or ceiling cladding, as a countertop or for the manufacture of furniture, has at least one carrier plate which is coated with at least one coating element, in particular with at least one decorative layer of decorative paper and thermosetting resin.
  • the support plate is usually a wood-based panel, for example a fiberboard, such as a high-density fiberboard (HDF) or medium-density fiberboard (MDF), or a chipboard or wood-based panel of oriented-scattered microfubers, a so-called O [riented] S [edge] B [oard].
  • a fiberboard such as a high-density fiberboard (HDF) or medium-density fiberboard (MDF), or a chipboard or wood-based panel of oriented-scattered microfubers, a so-called O [riented] S [edge] B [oard].
  • the decorative paper of the decorative layer can be printed with color and / or with a pattern or decor, for example with a wood or stone reproduction.
  • thermosetting resin such as melamine resin
  • overlay an abrasion-resistant layer
  • the overlay has thermosetting synthetic resin, for example melamine resin.
  • the overlay may further comprise fibrous, in particular cellulose-containing, material.
  • This fiber-containing synthetic resin layer may also be provided to improve its abrasion resistance with abrasion-resistant or abrasive substances, for example with corundum particles.
  • the overlay may consist of two transparent melamine resin-impregnated papers, between which a corundum layer is enclosed. Furthermore, corundum filled overlays are common.
  • a core or carrier paper layer of a plurality of papers impregnated with thermosetting synthetic resin, for example phenolic resin may be arranged on the side of the coating element facing the carrier plate.
  • This optional paper layer which preferably uses kraft paper as the paper, imparts additional hardness and impact resistance to the coating element and improves its staying power.
  • the underside of the carrier plate can be pressed with a so-called counter-pull, for example with a veneer or with another layer impregnated with thermosetting synthetic resin.
  • the various layers, so the decorative layer of decorative paper and thermosetting resin, the z. B. may be applied in the form of an overlay on the decorative paper, the carrier plate and the optional Backing in a single operation directly to so-called direct pressed laminate (D [irect] P [ressure] L [aminate]) pressed together.
  • z. B. in a first step from the decorative paper and the thermosetting resin, z. B. may be applied in the form of an overlay on the decor paper, and the optional core or backing paper layer produced a coating element.
  • the coating element is then pressed with the carrier plate.
  • the decor layer of decorative paper and thermosetting resin is produced in two separate operations on two separate production lines.
  • the decorative paper is printed on a first production line, the printing is usually done in the gravure printing process.
  • the printed decorative paper is rolled up again and transported to a second production facility for impregnation or coating with thermosetting synthetic resin.
  • the printed paper is then impregnated in a second operation or second method with the thermosetting synthetic resin and / or coated with the overlay.
  • the production of the decorative layer on two separate production lines or in two separate production methods is not very efficient, because the raw decorative paper has to be transported to two different production lines and inserted into each of them. It is thus spanned in the first production line for printing the paper, a first paper web of base paper and in the second production line for impregnating or for coating the paper, a second paper web of printed Stretched paper.
  • This production method is time-consuming and thus expensive.
  • two separate manufacturing plants require relatively much space.
  • a further disadvantage is that the two-time clamping of the paper web can lead to a change in the shape of the decorative paper and thus to a deformation or distortion of the printed pattern and to buckling and / or tearing of the decorative paper.
  • the object of the present invention is to further develop a method of the type mentioned at the outset and a production device of the type initially mentioned, such that the coating element can be manufactured efficiently, with kinks , Cracks or changes in shape of the printed fiber material or paper can be reliably avoided.
  • the present invention is fundamentally based on designing a series or inline production device, for example an inline production line, in which the fiber material or paper is printed in a first step and then further processed immediately by means of impregnation and / or coating. According to the present invention, therefore, the delivered fiber material or paper is printed in a production process and then impregnated and / or coated in the same production process.
  • the combination of printing and impregnation and / or coating in a production device or in a machine can be realized by arranging at least one impregnating and / or coating device in series or inline with at least one printing device.
  • the printing device can be arranged between at least one unwinding device designed for unwinding the fiber material or paper web and a first dip bath or a first coating device of the impregnating and / or coating device.
  • Unwinding device, printing device and impregnating and / or coating device are thus preferably arranged in series, for example on at least one production line or production line, for example on at least one impregnation channel.
  • the manufacturing device comprises the components of a conventional impregnating and / or coating device.
  • these components are arranged so that the stretched fiber material or paper web can be both printed as well as impregnated and / or coated.
  • the printing of the fiber material or paper web can be done by the method of gravure printing or by the method of digital printing.
  • the application of the method of digital printing is particularly advantageous because a digital printing device has a small footprint and thus can be easily integrated into conventional impregnation machines.
  • a digital printing device or a digital printing unit does not require expensive printing forms.
  • Other advantages of a digital printing device compared to a gravure printing device are lower investment costs and the possibility of simpler and less expensive decor change.
  • storage costs in the raw materials area can be reduced by means of a digital printing device, since a large number of decors need not be provided.
  • the fiber material or paper web is thus printed by means of at least one digital printing device.
  • This digital printing device fulfills the properties required for printing the fiber material or paper web and is preferably designed to print substantially the entire width of the fiber material or paper web.
  • Vorteihaft the digital printing device is designed to at least partially dry the printed fiber material or paper web.
  • the drying of the fiber material or paper web can take place by means of air and / or by means of ultraviolet radiation and / or by means of the method of near-infrared drying.
  • other drying methods such as UV drying and / or NIR drying can be used.
  • An advantageous embodiment of the printing device due to a comparatively low printing speed, has a comparatively short, for example a few meters, drying section.
  • the spanned fiber material or paper web in particular on its side facing away from the resin layer, be coated with at least one core or backing paper layer, wherein the core or backing paper layer at least one impregnated with thermosetting synthetic resin, for example with phenolic resin, fiber material, in particular Paper, such as kraft paper has.
  • thermosetting synthetic resin for example with phenolic resin
  • fiber material in particular Paper, such as kraft paper has.
  • the spanned fiber material or paper web of the coating element can thus also be applied to the carrier plate, for example to a wooden material plate, such as an MDF, HDF, in the same production process. , OSB or chipboard, or on a plastic plate.
  • the support plate on its side facing away from the coating element can still be coated in the same production process with at least one counter-pull, for example with at least one veneer and / or with at least one further thermosetting synthetic resin layer.
  • the coating element can be laminated to the carrier plate by means of a single-stage or by means of a two-stage process. From the coating element produced according to the invention, it is thus possible to use both D [irect] P ressure L [aminate] as H [igh] P ressure L [aminate] and C [ontinuous] P ressure L [aminate] as well as L [ow] P [ressure] L [aminate].
  • FIG. 1 shows a schematic representation of a first embodiment of a device according to the present invention, which operates according to the method of manufacturing laminate according to the present invention.
  • the production device 100 is designed to produce a decorative layer suitable for coating the carrier plate 60, wherein the decorative layer has at least printed decor paper and thermosetting synthetic resin.
  • This impregnation device 30 is designed to impregnate the clamped fiber material or paper web 50 with aminoplastic and thermosetting synthetic resin, namely with melamine resin. Furthermore, the impregnation device 30 could also be designed to coat the clamped fiber material or paper web 50 with a layer comprising resin, in particular melamine resin, ie with an overlay.
