    The invention relates to a method for influencing the visual appearance of a wood element as set forth in claim 1, and to a method for producing wooden floors or furniture panels according to claim 15 and the use of the inventive method for producing Hoizeiementen for the interior area, as in Claim 16 is given
    From DE 10 2008 012 391A1 it is known to provide a parquet-like floor element, which is provided with a soft cover layer, on the visible upper side with machine-introduced indentations in order to visually reinforce a natural wood grain of the cover layer. The indentations in the upper side are thereby introduced by a press ram or by a press roll. These indentations in the cover wood layer should have a relatively small depth of less than 0.5 mm. With these machine introduced imprints a floor element is to be achieved, which should have a high-quality, parquet-typical appearance even in a Deckhoizschlcht from a wood with little varied or relatively inconspicuous texture. Especially low-pore or in terms of grain relatively simple types of wood, such as beech, aolen be optically livelier designed by this embossing process. The disadvantage here is that the impressions produced by a press ram or a press roll in the cover layer have a regular, unnatural-looking character and will be repeated in certain sections with respect to arrangement or contouring or shaping. The degree of naturalness, which is achieved with these impressions, is thus unsatisfactory. In particular, natural-looking irregularities can not be achieved by the proposed embossing measures. 15/06/2011 16:13

    WO 2006/087155 A2 describes a method for the optical design of the surface of a Hofzschlcht According to this method, cracks or knotholes kn graze wood with a contrasting color, in particular with a filling in a contrasting color to the wood ausgefü The cracks or knotholes can also with a translucent or light-scattering filling material are filled, so that upon assignment of a light source for Bchtdurchlässlgen filling material illumination of the provided with the filling cracks The provided with a contrasting color filling cracks or knotholes emphasize the outline contours and also leads the filling compound to a closed, even Surface, whereby the wood layer is easier to clean Be) this known method, naturally occurring defects or defects in the wood by a contrasting colored filling compound quasi puttied and highlighted. The corresponding wood elements are sorted out of a batch or a lot of wood elements. The jeweMgen wood elements are evaluated by a professional quality and are those wood elements that have damaged areas sorted out and then repaired with contrasting color filling material.
    Furthermore, it is known to mill by means of manual milling operations groove-like, seeming like ruts or depressions in the surface of Holzdementen and to provide these groove-like depressions below with contrasting color filling material. However, the previously known methods are relatively uneconomical and unsatisfactory for mass production or for large-scale manufacturing.
    The present invention has for its object to provide a method for influencing or permanent change in the visual appearance of a Hoizelementes which generates as possible naturfich acting, in particular allocation-like irregularities in the visual appearance of the wood element or emphasizes and which miss at the same time should be as economically as possible, to be better suited for mass production or mass production.

    This object of the invention is achieved by the measures according to claim 1.
    An advantage of the measures according to the invention lies in the fact that wood elements are thereby processed whose optical appearance is markedly influenced, whereby the correspondingly treated or processed wood slats can be processed industrially or in the manner of a series production and this provision is also made in a relatively economical or cost-effective manner Scope is possible In particular, a defined or targeted production of wood elements is possible whose optical appearance is influenced by particularly naturally occurring or acting irregularities in the form of wood giant These irregularities are also visually emphasized, making many end users, inter alia, a particularly attractive, optical Appearance is built.
    However, a particular advantage of the measures according to the invention lies in the fact that even relatively poor quality wood, which has hitherto hardly been used as lumber, is increased in its utility value and virtually refined, and that due to the particular conspicuousness or non-distinctive character of the This means that the measures according to the invention can also be used to further process relatively inferior wood into high-quality wood elements, which also results in rejects due to damaged wood or due to second-hand wood Quality can be significantly reduced. Along with this, economic and ecological improvement requirements are better met.
    On the other hand, the given thicknesses or thickness dimensions of the processed hotelamelias result in an intensive and as far as possible distributed formation of cracks in relation to the surface or the subsequent visible surface wooden lamellas N2011 / 02800 15/06/2011 16:14

The corresponding cracks are particularly natural running and represent the viewer particularly randomly acting irregularities or Konturvertäufe. In addition, a lengthwise limited cracking is achieved by the relatively small volume or thin wooden slats and a völgge, longitudinal splitting of the wood elements or Holzlamelien held back , Nevertheless, the measures specified produce numerous cracks, some of which also extend over the entire thickness of the hotetail gaps, as a result of which it is also possible to achieve sufficiently maikant recognizable crack widths.
    An essential factor for achieving as natural as possible cracks is defined by the relatively high wood moisture of the Hoiziamelen immediately before the technical drying in particular intensive and reliable withdrawal of wood moisture from the wood slats an intense or reliable incoming yet controlled cracking in the wood slats achieved technically controlled and deliberately induced, natural-looking cracks are created in Spezielen in the course of technically assisted or accelerated drying of the wood slats, socfass also a large-scale industrial production or the most economical ready division of relatively lively acting or relatively heavily structured wood elements is possible
    By introducing a filler into the technically or artificially hostel-led and yet extremely natural acting rosse, the visual appearance of Hoizeiemente in a positive sense grazed influenced. In addition, the practicality of the wood element is increased by completing the high-speed, naturally-acting crack discharges with hardening filling mass. This, in turn, results in a much simpler cleaning or a longer-term hold-up and by avoiding sharp-edged furrows or by covering or embedding wood slants in the wood Area of the furrows or the surface of the hooves minimizes the risk of injuries to persons The correspondingly made wooden elements can therefore also be used without problems as floor coverings for the living area or interior area.

    Also advantageous are the measures according to claim 2, since such a FüB mass on a polyurethane basis in the flattened state offers a high mechanical strength and a very best connection or bonding with the wood material allows in particular relatively wide cracks can be completed quickly and reliably or poured out and leveled without the risk of later breaking out or Heraustellens of the filling material is present in particular, such a filler remains particularly durable in the cracks of Hoizefementes, so that even in the longer term no optical and use-technical impairments occur. In addition, the polyurethane-based filling compound offers a long-term, relatively low shrinkage and low stress crack bridging and a low degree of exotbermy in the course of the curing process. In addition, due to the quasi non-existent water absorbency of the filling compound, in particular by its high hydrophobicity, a use as a floor element or as a furniture element favors
    Also advantageous are the measures according to claim 3, since thereby a Oberquallen or Vorepringen of viscous filling material on the underside dm1 Hotzlamel - len is avoided. In addition, this can be done as complete as possible filling the cracks with the filling compound, after the carrier layer prevents unwanted discharge or outflow of viscous filling material Another advantage is that even relatively wide cracks can be filled with viscous or pourable filler In this way, the quality of the filling process using originally flowable or pasty filling material can be substantially increased and the time required for this filling process can be kept as low as possible without any gradual shrinkage or settling or flowing out of the filling compound in the course of the hardening phase.
    Also advantageous are the measures according to claim 4, since a good ratio in terms of weight and strength or stiffness of the correspondingly produced wood element is achieved. In addition, such a structured wooden element is relatively inexpensive to produce and a relatively thin wooden lamella is sufficient to provide a striking, vibrant appearance. 15/06/2011 16:16

    But also the adhesion or the Ausreißfestigkett the filling material is positively influenced, after a strong bonding or reliable connection to the present in the cracks of the wood elements filling material is achieved by the relatively open-pored wood structure of Trflger-Schlcht made of softwood or softwood Dies is particularly advantageous in over the entire thickness of the Holzlameilen extending, relatively wide cracks. In particular, crack widths of more than 5 mm or of up to 30 mm can thereby be easily and permanently bridged with the filling compound.
    Also advantageous are the measures according to claim 5, since such wood slats produce intensive, technical drying a relatively optimal or very attractive, varied crack pattern. In particular, in such wooden slats extremely natural-looking, over the width and length of the wood slats relatively well distributed cracks can be generated. A particular advantage of the use of leeks is that a high availability of such hardwood voriiegt and in such a wood, a visually interesting or lively crack pattern can be generated. In addition, a relatively economical procurement of such woods is guaranteed
    In particular, can be achieved by a high-temperature drying chamber, a relatively economical cracking in the Holzlamelien, creating a basis for a targeted production of such wood elements is particularly characterized by a achieved good continuity in the manufacturing process or a high Prozeßatebifität
    However, the measures according to claim 8 are also advantageous, since within a relatively short period of time a technically controlled or targeted Ries formation is achieved in the hoizirs and furthermore the economy of the process is relatively high due to the relatively short exposure time
    Also advantageous are the measures according to claim 9, since this will include a sufficiently high, naturally conditioned wood moisture in the Holzlameilen N2011 / 02600 15/06/2011 16:17
    No .: R223 P. 010/041 853 # «· · * * * * *:::::::::::::::. It is possible to do this without the need for costly technical measures. The minimum moisture content ensured or maintained by the specified measures favors intensive crack formation during the subsequent, relatively rapid, technically accelerated drying process. The economy of the manufacturing or influencing method according to the invention can thus be kept relatively high by at least one of the measures according to claim 9.
    Furthermore, the measures according to claim 10 are advantageous since this can be used to intensify the intensity or the degree of crack formation, in particular by conditioning or increasing the moisture content of the wood. In addition, it can also be raised to a higher moisture content by such wood slats, which, for example, by long-term storage or outdoor drying have unfavorably low wood moisture content, so as to achieve the best possible crack pattern generation. In addition, it is thereby made possible to achieve within a pile of wood to be processed Hoiztameüen a relatively uniform wood moisture of the individual wood slats and thus to achieve the most uniform cracking in relation to the total to be treated wood slats or in relation to this batch of wood slats.
    In addition, the measures according to claim 11 are advantageous because thereby the filling compound can be introduced into comparatively narrow or fine cracks and thus th possible vollzähliges and complete rolling the kunstiteh or technically caused Risae guaranteed in the wood surface is particularly by a spatula with the filler also relatively viscous or pasty and thus special shrinkage-free filling material are reliably introduced into relatively narrow or narrow cracks.
    Also advantageous are the measures according to claim 12, as this characterized those surface sections of Hofcdame, in which originally no cracks were contained, maintain their natural wood look or regain and thus the natural character of the wood surface of the wood element is guaranteed.

    In addition, the risk of tearing the FOllmasse from the cracks, as would be the case, for example, Schab- or Schnappenvorgängen the fold, held back.
    By the measures according to claim 13 as complete and complete filling of the existing cracks would be achieved with the filling In addition, thereby relatively wide cracks, in which the filler tends to discernible shrinkage in the course of curing, relatively ebenftächig or flush to the visible surface of the wood element.
    By the measures according to claim 14, a visually appealing appearance is ensured and the caused by the lapse of the filling mass stains on the wood surface can thus be completely eliminated. The visual appearance of the wood surfaces as well as the filler-filled cracks are thereby positively influenced
    Finally, the invention comprises a method for producing wooden floors or furniture panels with a useful or decorative layer of wood, which Nutz- or decorative layer is glued on at least one carrier layer, as indicated in claim 15.

Some of the highly schematically represented method steps are optionally applicable and do not belong to the scope of the invention according to the process. It is essential that by a plurality of sequential or parallel operating procedures ultimately a schematically illustrated in Fig. 9, exemplary constructed wood element 1 is formed, whose visual appearance is significantly affected by various technical procedures So represents only an exemplary design of the wood element 1 produced by the method according to the invention.
    Naturally grown wood is used as the starting material for the production of a wood element 1 indicated in FIG. 9, which wood is present in the form of round wood 3 or in the form of so-called woodland blocks after the strike of corresponding tree species. Such roundwood 3 has a plurality of naturally-developed features, such as branch lugs 4, constrictions 5, thickening, scar-related growth or the like. In addition, naturally grown wood is for its typical, naturally formed, unique grain or texture N2011 / 02800 15/06/2011 16:19

    Such roundwood 3 is divided in a conventional manner in sawmills in individual posts 7 or cut out to Hotzbafeen. The corresponding posts 7 are either air-dried according to the prior art - Fig. 2 - o increasingly subjected to a technical drying to reduce the wood moisture of the posts 7 and the wood mainly for use indoors , in particular for furniture production, to make them suitable. The air drying or the technical drying is typically carried out in a stack of wood 8 from a plurality of juxtaposed and stacked posts 7 with interposed intermediate layers 9, in particular so-called stacking slats or Zwischengittem, which serve for better ventilation or air circulation in the vicinity of the post 7.
    According to the prior art, this wood drying, whether by outdoor drying or by a technical drying with Warmkiftumwälzung, as gently as possible or long-term, so that in the wood to be dried as possible, no cracks. Especially with a gentle or temperaturkon-controlled and long-term drying such as drying errors be-recorded cracks or splits of posts 7 or wooden beams can be avoided. In the illustrated in Fig. 2, classic Freflufttrocknung of wood roofing 10, such as covers or warehouses are typically provided to protect the wood to be dried from the weather, especially against rain or snow, largely and to achieve a gentle, anmähfi-che drying ,
    The posts 7 produced from the roundwood 3 typically have a thickness 11 of one inch or more. Usual are posts 7 made of hardwood with a thickness of 11 between 30 mm and 100 mm, with gradations range of 10 mm are typical. These posts 7 with a thickness of 11 between 25 mm to about 100 mm are then as gently as possible air-dried, to then as so-called N2011 / 02000 15/06 / 2011..16: 2ß

    Carpenter wood can be further processed by furniture processing companies.
    The process steps or measures illustrated in FIGS. 1 and 2 serve to be able to provide the posts 7 or wooden elements, which are ultimately to be processed by a joinery, as dry and free of cracks as possible in order to prevent subsequent shrinkage and unraveling of the wooden components produced from the posts 7, which were processed, for example, to furnishings, to avoid or detain.
    In contrast, it is provided according to the method according to the invention to produce a plurality of cracks in the wood and thereby to ensure as natural as possible cracks. In particular, a targeted, technically supported cracking is sought, which ensures good reproducibility and creates a basis for production or provision on a larger scale
    In FIGS. 3, 4 process steps of the method according to the invention are schematically illustrated. According to these measures, a plurality of relatively thin wooden slats 12 are provided. These wooden slugs 12 form part of the final hoisting element 1, as exemplified in FIG. It is expedient to form the wood slats 12 of rough-sawn post 7. The posts 7 are divided in relation to their thickness 11 on several comparatively thin HotztameUen 12, which can be done for example with a band or circular saw. For example, with posts 7 having a thickness 11 of about 30 mm, a plurality of wooden slats 12 having a thickness 13 of about 7 mm can be produced by sawing splitting of such posts 7. In particular, by multiple sawing operations, for example from a post 7 or from a pre-cut Hotzbaken, several wooden slats 12 with a length 14 of at least 200 cm, a width 15 of at least 10 cm and a thickness 13 between 4 mm to 10 mm, preferably about 7 mm, are provided. Preferably, such wooden lamellae 12 are made of posts 7 or roughly pre-cut wooden beacons by means of a N201t / 02800 15/06/2011 16:21

    Ribbon or circular saw cut to size. Alternatively, it is sefestverständlich also possible to produce directly from the round timber 3, the respective wooden slats 12, in which case preferably band saw units are used. The provided wooden slats 12 may be trimmed or unhemmed and, depending on the dimension of the starting material or post 7, a width 15 between 10 cm and 25 cm, preferably of approximately 17 cm.
    A process-technically favorable length 14 of the wooden slats 12 is at least 200 cm or this length 14 can be between 200 cm and 500 cm, usually at about 300 cm.
    It is essential that the wood moisture of these Holzlameilen 12 is relatively high at least immediately before the technical drying This relatively high wood moisture of the wood slats 12 can be ensured by the natural wood moisture of the corresponding round timber 3. But it is also a natural or a technically controlled air conditioning possible by which a gradual drying is slowed down or the moisture content can be even increased by technical measures. It is expedient if the wood moisture of these Hoizla-mellen 12 more than 20%, in particular more than 40%, preferably between 30% to 70% A correspondingly high wood moisture can by direct further processing of geszNeutertem round wood 3, by technical humidification and / or slachgestettt or be achieved by suitable air conditioning.
    In FIG. 4, a wooden lamella stack 16 is exemplified, which comprises a plurality of juxtaposed and layered stacked wooden lamellae 12. These wooden slats 12 have a relatively high moisture content of wood after they were stacked in relatively short time interval after the strike of naturally grown wood or in a relatively short distance after cutting logs 3 to post 7 or to Holzlameilen 12 eodass by Air drying induced dehydration of the wood is still relatively low and a value of more than 20%, advantageously from about 40% to 50% in relation to the wood moisture of these Holzlamelien 12 voriiegt or guaranteed For example, by shading the wood slats 12 and Storage of the wood lamella 16 in a relatively humid environment, Ν2011ΛΒ800 15/06/2011 16:21

    According to an optional, particularly effective measure to ensure a minimum wood moisture, in particular to achieve the least possible dehydration of the wood or to increase the Holzfouchte of cut wood, in particular already produced wood slats 12, It is envisaged to use an active, technical moistening device 17, such this has been illustrated schematically in FIG. Such a moistening device 17 may comprise a distribution device 18 for water. This distribution device 18 can be defined in a simple manner by a sprinkler device which comprises a plurality of spray cans 19 for distributing natural water. The water, which is distributed as finely as possible or atomized via the moistening device 17 or via the distribution device 18, acts on it the wooden slats 12 a. In particular, water is applied to the wood lamella stack 16, for example sprayed on it, so that the wood moisture of the wood lamellae 12 is kept relatively high or above a lower limit, which is expediently about 20%
    However, active technical moistening by means of a moistening device 17, as has been schematically illustrated in FIG. 5, can also be dispensed with. This especially when relatively freshly felled wood is further processed or the gradual wood drying process, for example by air drying, is held back longer term. A long-term high wood moisture can be accomplished in particular by cool or shady storage of the round timber 3, the post 7 and / or the wood slats 12. Thus, a shading measure or an air conditioning device can be understood or used analogously to a moistening device 17 to ensure sufficient wood moisture in the wood slats 12. N2011 / 02800

    An essential measure of the inventive method is that the relatively moist, that is a relatively high, for example, almost the original wood moisture having Holziamellen 12 are subjected to a relatively rapid or intensive, technical drying, as this method measure in F. 6 exemplified and schematically illustrated. In this case, FIG. 6 outlines an exemplary embodiment of a so-called drying chamber, in particular a high-temperature drying chamber 20, for achieving rapid and intensive removal of moisture from the wood lamellae 12, which were typically introduced into the Hoohtomperatur drying chamber 20 in the form of a wooden lamella structure 16. Such a high-temperature drying chamber 20 preferably comprises at least one heat exchanger 21 for supplying heat energy into the interior of the drying chamber and at least one fan 22, for example an induced draft fan for circulating the heated drying air or the so-called vapors inside the drying chamber.

This cracking appears arbitrary or completely natural to the viewer, which positively affects the appearance of such a hoizbaut. Due to the relatively small thickness of the wood slats 12 is also achieved that a possible distributed arrangement of the cracks 23 in relation to the length 14 and width 15 of Hoiziameilen 12 is present. In contrast, would be relatively thick heating elements, for example, from a thickness of 20 mm, a rather concentrated cracking or a relatively poor crack distribution with respect to the surface of the wood element occur or even a Hoizspaltung occur. In addition, it is achieved by means of these relatively thin wooden lamellae 12 that individual, relatively wide cracks 23 can arise, which extend over the entire thickness 13 and thus breakthrough ozone darotollon. Zudom may include a relatively large oohmolor giant 29 ontotohon which extends only over part of the height or thickness 13 of the hoizemiles 12.

    It is particularly expedient in this case to select the filling compound 24 with respect to its coloration in such a way that it has a color that contrasts with the wood color or the wood lamellae 12. It is expedient for wood laths 12 made of a dark type of wood, for example moose, cherry, Teak, nut, or the like, to provide a comparatively light color for the filling compound 24. In contrast, it is expedient to use a relatively dark hue, for example, brown or black as a hue for the filling material 24 in wood species with relatively light wood color, such as ash, maple, birch or the like, so that the filling material 24 in contrast to the appearance of the wood strongly contrasting By a high-contrast color selection of the filling compound 24 against the wood color of the wood of the wood slats 12, the at least largely filled cracks 23 in the surface of the wood slats 12 are emphasized or highlighted.

The color of the filling compound 24 is expediently chosen such that the corresponding jointing or filling compound 24 is clearly contrasting with the color of the respective type of wood. For example, in the case of dark wood species, a relatively bedded filling compound 24 is used, for example in white and / or yellow-blue ones. and vice versa It is also effective to choose a hue that strongly contrasts with the natural wood color in the area of the basic or spectral colors, such as red, orange, yellow, green, blue, indigo or violet Special effects are also achievable if the filling compound 24 has metallic shades, such as e.g. gold, silver, aluminum, steel gray or the like.
    The paste-like or viscous filling material 24, which subsequently hardens gradually and fills the previously existing cracks 23 permanently, is preferably formed by a polyurethane-based filling compound 24. The filling capacity of the filling compound 24 is chosen such that cracks 23 with a mean width of more than than 2 mm, preferably of up to 20 mm can be filled permanently. This filling should be as far as possible ebenflflchchig or flush and free of pores with respect to the surface of the wooden slats 12. A filling compound 24 based on polyurethane allows this in voretetthafter way.

    As appropriate, it has further been found to select the wood for the wood slats 12 from the plant family of beech plants, bisbesondere the wood from the genus of oaks are particularly well suited to achieve a harmonious, gutwetterverarbettbares crack pattern in the wood slats 12. A particularly suitable or preferred type of wood is formed by the Turkey oak, which occurs naturally in Central and Southeastern Europe and in addition to a good behavior with respect to the Rissbitdung in thermal action, also offers increased efficiency Alternatively, it is also conceivable in terms of texture relatively simple Wood species, such as hornbeam beech or beech by means of the method according to the invention to process, in particular a technically controlled induced Rissbüdimg.
    An intensive or relatively aggressive removal of moisture from the wood slats 12 is achieved mainly by using a Hocbtemperatur-drying chamber 20. It is expedient to apply the relatively high wood moisture in the high-temperature drying chamber 20 introduced wood slats 12 during a high-temperature drying phase with a temperature of more than 80 "C, in particular between 100 ° C to 200 ° C and below this Temperature effect to effect rapid drying of Holzlamelien 12. In particular, for a variety of wood species, particularly for the treatment of Turkey, it has been found that the corresponding HoizlameNen 12 at a temperature between 150 eC to 200 * C over a period of 4 to 8 hours to apply. The corresponding temperatures relate to the ambient temperature or to the air temperature in the area around the wood slats 12 to be dried.
    An effective thermal treatment to achieve an appealing and at the same processing-technically or process-technically favorable crack formation in the wood lamellae 12 comprises a process with three process stages. In a high-temperature phase while the wood to be treated or the temperature of the ambient air is heated to 150 eC to 200 ° C.

The atmosphere within the high-temperature T rockenkammer 20 is influenced or determined by the wood properties, in particular by the respective water content. On the other hand, during the third phase, which is defined by the cooling and conditioning phase for the wood grains 12, water is injected into the treatment chamber. During phase 1, especially during the start phase, the temperature in the high-temperature drying chamber 20 becomes 100 within a few hours C. The temperature is then increased to 120.degree. C. to 140.degree. C., whereby the moisture content in the wooden lamellae 12 rapidly decreases. In the second phase, which corresponds to a high temperature drying phase with intensive heat treatment, the temperature is lowered to 150.degree C increased to 200 ° C. A subsequent third phase, in particular a so-called cooling and conditioning phase, serves for cooling and humidifying, in particular for stabilizing the wood lamellae 12. In this cooling process, the temperature in the drying chamber becomes 80 ° C. to 90 ° C. lowered. At the same time, the moisture content of the wood slats is increased or maintained to about 4% by a moistening process takes place in the high-temperature drying chamber 20 over several hours. This moistening process can preferably be carried out by a moistening device 17, which contains a plurality of spray nozzles of water or drizzle into the high temperature As a product of this thermal and wetting treatment arise on the one Hoizfamellen 12, which with a variety of technically initiated, particularly natural-looking cracks 23 Obersät or are provided, and on the other vapors, which consist to a large extent of water vapor.

    In addition to this cooling or conditioning phase, which takes place immediately after the thermal treatment of the wood slats 12, it is also expedient to set a minimum wood moisture of the wood slats 12 before the technical drying. This can be done by wetting the HolzlameHen 12 with a spray or drizzle of water, as was indicated in Fig. 5 by way of example. Likewise, it is possible to ensure a minimum wood moisture of the wood slats 12 before the technical drying, by providing for a corresponding air conditioning of the wood slats 12. In particular, it is possible by shading the HolzlameHen 12 and / or by cutting the wood slats 12 from a larger or larger volume wood block, in particular wooden post 7, in a sufficiently short period before the technical drying or in a sufficiently short period after the Schlägerung of according Hotz, a favorable for the RissbHdung, relatively high wood moisture in the wood slats 12 to ensure.
    As can best be seen from the schematic representations according to FIGS. 8, 8, the filling compound 24 which has passed or diffused on the surface of the wood lamellae 12 in the course of the application or puttying process 25 is abraded after curing or after sufficient hardening. so that the wood surface is freed from the over the cracks 23 excess filler 24 and the filler 24 predominantly only in the relatively catch or wide, thermally initiated cracks 23 remains For grinding excess, surface-aged filling compound 24, it is expedient to use a belt grinder 31 , This belt grinding device 31 processes the final visible or useful surface on the utility or decorative layer 32 of the wood element 1 according to FIG. 9 such that the filling compound 24 remains as possible only in the cracks 23 with a width of more than 2 mm
