Definitions

  • the invention relates to a method for manufacturing wooden elements, such as wall boards or floor boards, having an antique or rustic look at the side which is in view when the element is being used.
  • the invention furthermore relates to such wooden elements, particularly wall boards or floor boards.
  • Wooden elements such as floor boards used for assembling a rustic or antique looking piece of furniture, wall or floor, are known to be subjected to a lye treatment. Wooden elements, such as boards, are immersed in a bath of lye liquid. Subsequently the wooden elements are dried.
  • a further object of the invention is to provide an efficient and controllable process for treating wooden elements, such as wall boards or floor boards, with lye.
  • the invention provides a method for manufacturing wooden elements having an antique or rustic look at a/their side which is in view when the element is being used, wherein a sight side of wooden elements of planed new wood is treated with lye by applying a lye liquid on the surface of the sight side.
  • lye liquid such as a caustic soda solution
  • applying the lye liquid takes place by application, which can easily take place in a controlled manner.
  • the application can be immediately adjusted to the quality and the structure of the wooden elements to be treated. Drying times will thus become predictable.
  • the lye liquid is efficiently used, particularly because the other sides of the wooden element, such as the other main side of a board, do not have to be subjected to a lye treatment.
  • controllability of the process is further enhanced when the application takes place using manipulable or operable application means.
  • the application means and the wooden elements are moved with respect to each other during application.
  • the process is further enhanced and accelerated if the applied lye liquid is pressed onto the surface of the sight side.
  • the pressing takes place using the application means.
  • the lye liquid is thus optimally used.
  • the lye liquid is applied using application rollers along which the wooden elements are passed. The application then takes place while transporting the wooden elements.
  • the application rollers may partially extend into a lye liquid bath, wherein the sight side of the wooden elements is supported on the application rollers.
  • the application rollers are each time automatically moistened with lye liquid.
  • the side of the wooden elements opposite the sight side may be engaged by pressure rollers, preferably driven pressure rollers.
  • the pressure force is therewith also used for transport.
  • the pressure force can be set.
  • the sight side is treated with moisture, particularly water, in order to decelerate the lye-treatment process, particularly stopping the process.
  • moisture particularly water
  • This may for instance be done by rinsing, but preferably by sponging with water, because then the quantities of applied moisture can be properly controlled, so that the surface does not become too wet.
  • the surface may be struck off with a wiper or the like in order to achieve an as dry as possible surface.
  • the boards are subsequently dried.
  • Agents, such as vinegar may be added to the moisture or the water, in order to fully stop the lye-treatment process. In that case the wooden elements have been subjected to a single lye-treatment, and may then be referred to as red-lye treated.
  • the wooden elements are subjected to the lye-treatment at least twice consecutively.
  • a so-called double lye-treated or grey lye-treated wooden element may be obtained in this way.
  • the process of double lye-treatment is enhanced when a period of rest is put in between the first and second treatment of the wooden elements.
  • the process of double lye-treatment is further enhanced when in the period of rest the lye-treated sight sides of the wooden elements are kept against each other in pairs.
  • the process of double lye-treatment may be ended when after the lye liquid has been applied for the last time, the sight side after application of the lye liquid is treated with moisture in the above-mentioned manner, such as by wiping the surface with moisture, such as by sponging with water, to slow down the lye-treatment process on the wood, particularly stopping it, and is subsequently dried.
  • the sight sides of the wooden elements, after applying the lye liquid, are treated with a lime-water solution.
  • the concentration of the lye (for instance caustic soda) in the solution (water) is kept in the range of approximately 1:1 -1:5, in volume-ratio lye agent (dry substance) - water.
  • lime has been added to the lye liquid, preferably in an equal volume-ratio as in which the lye agent has been added to the water of the lye liquid.
  • the lime in the solution extracts moisture from the treated surface of the wooden elements as a result of which the drying over the entire surface will take place more quickly.
  • a method for manufacturing wooden elements having an antique or rustic look at an/their side which is in view when being used wherein a sight side of wooden elements of planed new wood is treated with lye using a combined lye/lime solution.
  • the invention provides a wooden element, such as a board, particularly a floor board, obtained using the method according to the invention, treated with lye at a sight side only.
  • the used wooden elements are preferably made of hard hardwood, such as oak.
  • the lye-treatment station I shown in cross-section in figure 2, comprises a tank 4 in which a lye liquid 5 is present.
  • An -optionally driven- application roller 6 extends in the lye liquid 5, the surface of which application roller is provided with circumferential grooves 8 (figure 2), which between them leave cylindrical circumferential planes 9.
  • a transport and pressure roller 7 driven by an electromotor 14 is positioned, which transport and pressure roller 7 can be adjusted as to height in the direction G, in order to set the pressure force exerted on the board 1.
  • the board 1 By driving the transport roller 7, the board 1 is pulled in longitudinal direction through the intermediate space between rollers 6 and 7, wherein the lower side, the sight side 2, comes into pressed contact with the surfaces 9 of the application roller 6. There is lye liquid on said surfaces 9 and in the grooves 8, which lye liquid is taken along when the roller 6 rotates through the lye liquid 5.
  • the sight side 2, which is at the bottom, is provided with a layer 20 of lye liquid over its full surface under pressure force.
  • the board 1 After the entire board 1 has been passed in the direction A, between both rollers 6, 7, the board 1 is rotated about its centre line in the direction D, so that the sight side 2 faces up. In that orientation the board 1, supported in station II on a (driven) roller path 10, is transported over it in the direction B. Meanwhile the lye-treated surface 20 of the sight side 2 is sponged using a water moisturised sponge 11, that is reciprocated in the directions E, as a result of which the lye-treatment process is stopped there. After that, in station III, the board 1 with the sight side 2 facing up is placed on a basis 12. Here the board is dried, for instance for 24 hours. Alternatively the boards may be dried standing up, for instance placed in a rack, the advantage being that puddles on the surface are prevented. After that the dried boards that are single or red lye-treated, are discharged in the direction C to a storage.
  • FIG 3 the process for double or grey lye-treatment of the boards 1 is shown.
  • the boards first go through station I, and are subsequently stacked in a station IV, supported on a basis 12, wherein the boards 1 are placed in pairs with the sight sides 2, on which the lye layer 20 is present, against each other.
  • the stack 13 is sufficiently high or the wanted drying time has passed (for instance one quarter of an hour) the stack 13 is turned in the direction F, so that the boards placed first are now on top. From the top down boards 1 are taken away and they are passed again through station I. In this sequence of steps it is achieved that the boards 1 will approximately have the same drying time in station IV.
  • the boards 1 After passing through station I again, the boards 1 pass through the stations II and III, in order to be subsequently discharged as well in the direction C to a storage.
  • the boards 1 have only been provided with a lye layer 20 at the sight side 2.
  • the lye layer may be thinner than 1 mm.
  • the boards after passing through the lye-treatment station I can be treated in a subsequent station (not shown) with a lime-water solution.
  • Said lime-water solution may be applied in any suitable manner, for instance using a sponge or a roller.
  • the lime extracts moisture from the treated surface of the boards, which accelerates the drying over the full surface.
  • the concentration of the lye (for instance caustic soda) in the solution (water) may advantageously be kept relatively low, preferably in the range of approximately 1:1 - 1:5, in volume ratio lye agent (dry substance) - water.
  • the lye-treatment process will cause white stains on the wood surface, which give the lye-treated surface a special effect.
  • lime is added to the lye solution, so that a lime-lye solution is used.
  • the lime on the surface of the wooden element extracts moisture again from the wooden element, due to which drying over the full surface may be speeded up.
  • the lime in combination with the lye-treated surface, also provides a particular colour effect.
  • the lime may for instance be added to the water of the lye solution in an equal volume ratio as in which the lye agent has been added.
  • the manner of applying the lye solution may be diverse, such as pouring, brushing, sponging, spraying, rolling.
