Description

Title: Wooden plank, and method for treating a wooden plank
The present invention relates to a method for treating wood, particularly surfaces of wooden planks or plates for use as floor covering or floor parts. This may involve solid parts or laminated parts.
5 Aim of the invention is to treat a wooden floor plank in such a way that the wood is protected well against influences of use or surroundings and/or the wood requires less maintenance. Furthermore, for some applications it is desirable that the wooden surface has an "old" or even 10 "antique" impression, and the present invention also aims to meet this desire.
To this end, according to the present invention, a main surface of a floor plank is treated by applying an irregular 15 pattern of mutually perpendicular and parallel grooves in the surface, wherein part of the grooves is arranged parallel to the grain of the wood and part of the grooves is arranged perpendicular to the grain of the wood, and wherein the grooves have depths distributed over the range of 0.1 - 5 mm 20 and have widths distributed over the range of 1 - 2 mm. A
filler is applied in the grooves, wherein the composition of the filler is: [a] a combination of an oil and a wax; or [b] a combination of an oil and an acryl varnish; 25 or [c] a combination of an oil and a wax and an acryl varnish; or [d] a combination of a wax and an acryl varnish; or [e] an oil.
30 Further, the present invention provides a floor plank comprising a main surface having therein an irregular pattern of mutually perpendicular and parallel grooves in the surface, wherein part of the grooves is arranged parallel to the grain of the wood and part of the grooves is arranged perpendicular 1037481 2 to the grain of the wood, and wherein the grooves have depths distributed over the range of 0.1 - 5 mm and have widths distributed over the range of 1 - 2 mm. The grooves are at least partly filled with a filler, wherein the composition of 5 the filler is: [a] a combination of an oil and a wax; or [b] a combination of an oil and an acryl varnish; or [c] a combination of an oil and a wax and an acryl varnish; 10 or [d] a combination of a wax and an acryl varnish; or [e] an oil.
Thanks to the features proposed by the present invention, a floor has a relatively large surface area with spaces for 15 micro-storage. These spaces can be filled with a finishing material such as an oil and/or a wax and/or a varnish. As compared to a flat surface, the micro-storage spaces can contain more of this finishing material. Consequently, spike heels, chairs and heavy objects will have an abrasive wearing 20 effect to a much lesser extent, and it will take longer before spilled water, wine or chemicals affect the wood surface. Further, a floor provided by the present invention requires less maintenance.
25 These and other aspect, features and advantages of the present invention will be further explained by the following description with reference to the drawings, in which same reference numerals indicate same or similar parts, in which indications "below/above", "higher/lower", "left/right" etc.
30 only relate to the orientation displayed in the drawings, and in which: figure 1 schematically shows a standard floor plank; figure 2 schematically shows a floor plank provided with grooves according to the present invention; 35 figure 3 schematically shows the floor plank according to the present invention in which the grooves have been filled.
Figure 1 schematically shows a floor plank 1 with a main surface 2. The main surface 2 is the surface that, in the 3 condition of use, when the plank is mounted, is visible, and will briefly be indicated as upper face. Such planks are manufactured by a sawing process and/or a scraping process, possibly followed by a s.anding process, having the result that 5 the upper face 2 is planar and that the fibers or hairs of the wood structure have been swept closed. When such surface would be treated with liquid agents, such as oil or varnish, only a small amount of liquid is deposited on and taken in by the wood. When pieces of furniture such as chairs are placed on 10 the wood, or when the wood is walked on, the small amount of protection agent only offers little protection. After a relatively short amount of time, bald places of wear emerge on the upper face, and another treatment is required again.
15 The present invention proposes to treat such a plank according to a two-step process. It is noted that the invention is applied advantageously in the manufacturing process of new planks, and can be added to an existing production line relatively easily, but the invention can also 20 be applied to already existing, older planks.
In a first step, the upper face is provided with a system of grooves or scratches.
The grooves/scratches may be applied in a direction 25 parallel to the longitudinal direction of the plank, or in a direction perpendicular to the longitudinal direction of the plank, or both. It is noted that the longitudinal direction of the plank typically coincides with the longitudinal direction of the grain of the wood, and grooves parallel to or 30 perpendicular to the wood grain seem "natural"; conversely, oblique grooves give the impression of a damage.
The grooves should have sufficient width and depth, but should of course not be too wide or too deep. Preferably, the depth is more than 0.05 mm, more preferably in the range of 35 0.1 mm to 5 mm. In any case, there is little sense in making the grooves deeper than 7 mm, and it is undesirable to make the grooves deeper than 10 mm. The width of the grooves preferably is in the range of 0.5 mm - 5 mm, more preferably in the order of 1-2 mm.
4
The length of the grooves is not critical.
Also, the mutual distance between the grooves is not critical: this may for instance lie in the range from 0.5 mm -20 mm, and in a possible embodiment the distance lies in the 5 range from 1-4 times the (average) groove width.
The grooves may be applied by making saw cuts in the upper face 2 using a rather coarse saw, for instance a circular saw, a band saw or a chain saw.
Alternatively, the grooves may be applied by selectively 10 sanding (or burning followed by sanding) the upper face, having the result that the softer parts of the wood are removed sooner and further than the harder parts. This may involve differences in hardness resulting from the annual growing process, but it may also involve the harder knots.
15 When the upper face 12 is provided with grooves in this manner, the product gives to an observer the impression that the product is worn in a natural manner.
Figure 2 schematically shows the result thus obtained in 20 the case of a floor plank 10 with a main surface 12. The grooves, which are preferably arranged in an irregular or random pattern, are indicated by the reference numeral 13. It is noted that the dimensions of the grooves 13 are shown exaggeratedly large for sake of clarity.
25 The figure shows that the grooves do not need to have mutually equal dimensions, and further it gives a more natural impression if there are differences. Further, the figure shows that the exact cross sectional contour of a groove is not critical.
30
In a second step, a protection agent or filling agent is applied in the grooves. This protection agent may precisely fill the grooves, but this is not necessary in practice, and the exact filling depth will in practice also depend on the •35 dimensions and the contour of the several grooves. Applying may for instance be done by spraying or by a brush. Applying may also be done by rubbing it in with a cloth, and/or one can apply a finishing treatment to the treated surface by rubbing with a cloth.
5
Figure 3 schematically shows a floor plank 10 thus manufactured according to the present invention. The filling agent or protection agent in the grooves 13 is indicated by the reference numeral 14..
5 It may be clear that the upper surface 12 provided with grooves 13 is capable of absorbing much more protection agent 14 as compared to the planar surface 2 as illustrated in figure 1. The grooves act as volume reservoirs where protection agent may remain and may be held by capillary 10 action. Further, the grooves accomplish an enlargement of the surface causing it to become easier for the protection agent to penetrate into the wood. Further, open wood fibers now end in the protection agent reservoirs again, causing the protection agent to penetrate into the wood easier and deeper 15 by capillary action.
The protection agent may have different compositions. The protection agent 14 may consist of oil, wax, or varnish, or a mixture of two or three of these components. The varnish may for instance be on the basis of acryl and/or polyurethane.
20 Further, pigment substances may be added to the protection agent if desired. If desired, the protection agent may be provided with metals and/or silicium and/or lime, and/or a chemical compound of said components.
When the protection agent 14 contains varnish, this 25 varnish will harden after some time. When the protection agent 14 is primarily on the basis of oil, the wood will hold the oil like a kind of sponge; when now a point load (such as the leg of a chair) is applied on the upper face 12, the oil will be pressed out of the wood (by pressing the open wood 30 structure closed) and form a thin protective layer on the wood. Therefore, it takes substantially longer before bald spots of wear emerge.
Thus, the present invention succeeds in providing a 35 wooden plank that requires less maintenance and has an antique character. It is noted that the planks may be applied carrying or non carrying, but if desired they may of course also be applied for manufacturing furniture such as cabinets, tables, chairs, etc. The planks may be solid wood, but it may also 6 involve thin wood laminate on a carrier plate, for instance fiber board.
It should be clear to a person skilled in the art that the present invention is not limited to the exemplary 5 embodiments discussed above, but that several variations and modifications are possible within the protective scope of the invention as defined in the appending claims.
Features described in relation to a particular embodiment can also be applied to other embodiments described. Features 10 of different embodiments may be combined to achieve another embodiment. Features not explicitly indicated as being essential may be omitted.
The reference numerals used in the claims only serve as clarification when understanding the claims with a view to the 15 exemplary embodiments described, and should not be interpreted in any way limiting.
