Definitions

  • the invention relates to a method for producing a printable single or multi-layer material web according to the preamble of claim 1 , and to a material web produced thereby according to claim 20 , and to an installation for producing a material web of this kind according to claim 22 .
  • printed paper specifically what are referred to as decorative films, is used within the context of industrial manufacturing.
  • this paper is generally printed by means of an intaglio printing process.
  • the print quality here, depends on various factors. As well as the quality of the printing material used, for example the paper printing web used, the quality primarily also depends on the surface structure of the printing rollers.
  • Decorative films of this kind which are often printed with imitations of wood, are used for producing printed or printable components of various kinds, specifically in particular for producing furniture applications, but also for producing floor, ceiling and/or wall applications. Furniture applications using decorative wood patterns are known for example.
  • corresponding decorative paper printed with imitations of wood and/or pre-impregnated decorative paper is glued to corresponding base panels which may consist, for example, of a medium-density or high-density fiberboard, in particular wood fiberboard. Since corresponding panels provided with decorative paper or pre-impregnated decorative paper, for example in the form of a furniture application or laminate flooring, have to withstand high stresses, laminate flooring must comprise an additional protective layer as the top layer, i.e. a corresponding plastics material layer, which is also referred to as an overlay layer.
  • PI-paper synthetic resin impregnation
  • material webs which for example comprise a plastics film layer as the top layer or consist of a plastics film.
  • the mentioned material webs to be printed can be not only single-layer but also multi-layer, it being possible for the bottom layer to consist for example of a decorative paper web and the layers positioned thereon to consist of other materials and to in addition comprise adhesive intermediate layers.
  • the top layer may consist of plastics material.
  • a category-defining method for producing a paper layer for a planar printed or printable component, for example in the form of a floor, wall, ceiling and/or furniture panel, is known from WO 2009/097986 A1 for example.
  • the printed decorative paper can then be resin-treated. This is generally and preferably carried out in that the printed decorative paper web is guided through an appropriate vat containing resin and subsequently dried under the influence of heat.
  • the printed paper web which has been treated and saturated with resin in this way can then be applied to wood panels by means of heating, for which reason a resin which can be re-activated under the influence of heat, such as amino resin, melamine resin or the like, is preferably proposed.
  • decorative paper is to be used which has not been resin-treated and which is to be coated on the printing side with a dye-absorbing material, subsequently printed and then saturated by means of resin.
  • the paper layer it should also be possible for the paper layer to be resin-treated from the underside prior to printing in a defined manner such that the upper region of the fibre structure having a low or no resin content preferably extends over a maximum of 30% of the thickness of the fibre structure.
  • the printed decorative paper web is preferably only resin-treated after the printing process has been carried out. If resin treatment occurs prior to printing, however, then only the underside of the decorative paper web should be saturated with resin, and specifically without resin reaching the printing side.
  • the dye-absorbing substance used can be applied to the decorative paper web by various methods. It is mentioned that the dye-absorbing substance can be applied separately or together with a sealing liquid, by means of rollers, sprays, doctor blades, blade coating methods, airbrushes, cast coating methods, film pressing methods, cloth pressing methods, curtain coating methods and/or by means of application using a slotted nozzle.
  • doctor blades for paper, cardboard, finishing or tissue machines is further known, for example, from WO 2008/037850 A1.

  • doctor blades of the kind described in WO 2008/037850 A1 can be used in various manners.
  • the described doctor blades can be used, for example, as scraper blades.
  • the doctor blade points counter to the direction of rotation of the roll.
  • the doctor blade described in the document can, however, also be used as a coating blade. In this case, the doctor blade points in the direction of rotation of the roll.
  • the object of the present invention is that of providing an improved method and an improved device for producing printable or printed single or multi-layer material webs, in particular for further processing to form printed base panels or construction materials, for example in the form of furniture, floor, ceiling and/or wall elements.
  • the present invention assumes, in the same way as the prior art, that the material web to be printed should be provided with a primer layer prior to printing.
  • a primer layer is applied, in an excess amount, to the printing side of the material web.
  • a doctor knife is used, which will also be referred to hereinafter as a doctor blade.
  • the spacing and preferably the orientation position of this doctor blade relative to the material web which is guided past can be adjusted such that the free-flowing or viscous material of the primer to be used runs onto this doctor knife and can be transferred in an adhesive manner from the doctor knife to the material web to be printed only in the desired pre-set layer thickness.
  • the excess material is then removed and collected.
  • the doctor blade, and particularly the tip thereof to be arranged for example between two rollers which are spaced apart (i.e. in general between two contact lines which are spaced apart and between which the material web is guided), such that the tip of the doctor blade lifts up from the coated material web, in the form of a hydrodynamic high pressure zone established between the doctor blade and the material web. Direct contact between the tip and the material web is thus interrupted.
  • the mentioned hydrodynamic high pressure zone which is similar to what is known as the aquaplaning effect, ensures an interruption-free start of the primer material on the entire width of the material web, in the exact pre-set layer thickness and at optimal quality.
  • the doctor blade does not interact with the surface of the material web 1 at the point at which the material web rests on the roller drum of a roller.
  • the doctor blade is arranged such that the tip thereof is spaced apart from the deflection rollers which may be present, i.e. outside what is known as the wrap region, on a roller on which the material web is in contact with the surface of a rotating roller.

  • FIG. 2 is an enlarged detail of the doctor knife in the orientation position thereof relative to the material web guided past said knife.
  • FIGS. 1 and 2 schematically show how a material web 1 to be printed can be coated with a free-flowing, i.e. at least viscous, material.
  • the material web 1 may be a film-like material web 1 of a pre-determined width.
  • the width corresponds to the use (not shown in the drawings) in typical printing cylinders of a printing press.
  • it may for example be an intaglio printing process, an inkjet printing process or another common printing process.
  • the detail of the press shown in the drawings may, in this case, be part of an entire printing press, since the method according to the invention can also preferably be carried out in what is known as an online process, i.e. the material web to be printed is continuously first coated and then correspondingly printed.
  • the material web to be printed is first appropriately pre-treated within the context of the invention, and then for example wound onto a winding station in order to be printed later, in a second separate step at a different time and optionally also a different location.
  • the mentioned material web may for example be a pre-impregnated paper web, specifically pre-impregnated decorative paper 1 ′.
  • a plastics film or plastics film web 1 ′′ can optionally also be used.
  • the material webs may be single-layer or multi-layer and, for example, the layer closer to the printing side 1 a may consist of or comprise decorative paper 1 ′ or a plastics film 1 ′′ and the other layers may consist of or comprise comparable or other materials.
  • a multi-layer decorative paper web can also comprise plastics film layers and, vice versa, a plastics film can comprise at least one paper layer on the side remote from the printing.
  • bonding agents or adhesive layers for example can also be provided between the individual layers. There are no restrictions in this respect.

  • decorative papers should be understood as meaning all pre-impregnates, film papers, thin films in a wide range of colour combinations, etc.
  • the material web 1 for example, in particular in the form of the decorative paper 1 ′, can be saturated using a wide range of resin solutions, for example melamine resins and urea resins in a wide variety of compositions, plastics acrylate compounds (e.g. Acronal, Acrodur mixed with various chemical additives), paper sized using starch sizing, AKD sizing or sizing agents in combination with acrylates etc.
  • resin solutions for example melamine resins and urea resins in a wide variety of compositions, plastics acrylate compounds (e.g. Acronal, Acrodur mixed with various chemical additives), paper sized using starch sizing, AKD sizing or sizing agents in combination with acrylates etc.

  • the application roller 2 is arranged above a primer vat 5 which is filled with the primer material 6 to be used. Said primer vat 5 is therefore located directly below the material web 1 in the removal direction A and in front of the doctor blade arrangement.
  • the mentioned scraper 4 is fixed to an adjustment mechanism 7 , by means of which a position and/or orientation of the scraper 4 can be adjusted, and thus in particular the doctor blade tip 44 can be correspondingly adjusted relative to the material web 1 .

  • good and adequate values are also achieved when the solids content is less than or equal to 70%, 65%, 60%, 55%, 50% or less than 45%.
  • a value of from approximately 45% to 55% is optimal in many cases.
  • the primer material used is miscible with or soluble in water.
  • a preferred primer material should be entirely miscible with water or soluble in water.
  • the primer material should have a low solvent content of less than 3%, in particular of less than 2%, 1% or even 0.5%. If the primer material in addition has a flash point of over 100° C., there are generally no problems even if the material has to undergo heat treatment prior to printing.
  • a primer material of this kind it is possible to print a printable material web 1 , in particular a printable pre-impregnated paper layer or pre-impregnated decorative paper in an optimal manner, which makes it possible to achieve far better printing results, in particular in an intaglio printing process (although an inkjet process or other printing processes can in principle also be considered).
  • the material web 1 which is pre-impregnated in particular on the printing side 1 a which web is in particular in the form of a pre-impregnated paper web 1 ′, has been coated with the mentioned primer, and once the primer has undergone at least an adequate drying or surface drying phase, the correspondingly pre-treated material web 1 can then be printed.
  • water-based intaglio inks having a solids content of from 5% to 35%, in particular of from 10% to 30% or of from 15% to 25% are used during the mentioned subsequent printing.
  • the preferably water-based intaglio inks should for example have a pH value of between 7 and 9, in particular a value of from 7.5 to 8.5.
  • Particularly good results can be achieved when the printing inks have a flow rate of from 13 seconds to 30 seconds according to DIN standard 53211/4, already described with reference to the primer material.
  • Preferred values are, for example, of between 18 seconds and 25 seconds.
  • the printing inks may further comprise binders.
  • the binder of the individual basic colours preferably consists of casein. Furthermore, a blend of the binder casein or other binders common in ink production can also be added to the printing inks.
  • the use of the primer ultimately makes it possible above all to also smooth the paper and/or film web to be printed.
  • this is also a layer which is applied and which smooths unevenness in the decorative paper web.
  • the material used is also a type of bonding agent, which acts as a bonding agent for the printing ink which is to be applied. The significantly improved printing results can thereby be achieved.
