IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method for manufacturing a plywood layer, a method for manufacturing a beam-like wood block for manufacturing the plywood layer, and essentially by such A plywood layer and a beam-like wood block produced by the method and a device for carrying out the methods. Among these methods, a special adhesive mainly composed of a polyurethane can be used. [Prior Art] It is well known that the manufacture of plywood layers is a production technique for the manufacture of decorative, high-quality surface materials made of solid wood. Here, in the manufacture of a general plywood layer, the round material is peeled or peeled, and then the round material is sawn into two, three, four or other (commonly known as slats) and subsequently watered, usually It is for several days under the temperature increase to facilitate the subsequent cutting of the plywood layer, commonly known as planing. Then, the cutting process produces plywood layers of different thicknesses, for example, a plywood layer of about 0.5 mm thickness, depending on The cutting process, therefore, in the resulting product, we are able to be between the commonly known as the plywood layer (horizontal or vertical planing), commonly known as the peeled plywood layer (rotary planing) or the support (eccentric rotary planing) Identify. The most common planing, horizontal or vertical planing system illustrated in perspective is shown in Figures 15 to 17. Figure 15 illustrates a bisector 10 that is sliced along the direction of the wood fibers. On the other hand, Figures 16 and 17 disclose a planing transverse to the fiber direction. After the cutting process, a scrap board i 〇 is left, which is also referred to as "liner", as shown in Fig. 17. For technical reasons, the liner cannot be processed into a plywood layer because the brackets in the cutting equipment create 1128l2.doc • 6 - scrap that cannot be further processed. The resulting unprocessed plywood layer typically has a thickness of from about 0.45 mm to about 2.5 mm, preferably from 〇45 to 〇8, preferably (10). ◦ Dry for a few minutes. In the event of severe wrinkling or "bending", the plywood layer is otherwise subjected to a processing step. Subsequently, the dried unprocessed plywood layer is cut by size and classified by quality. For this size-based cutting, high material losses must be accepted, which can be as high as 60%. ', the mother of the package J cutter, and the size of the cut, can produce a (for sale) plywood layer with a surface area of about 0.6 m2. The problem of the manufacture of the plywood layer, which is complicated and wasteful, is even more serious because the raw materials are natural products "wood" and "tree". Here, it is often impossible to predict whether a round material used in the manufacture of plywood will produce a reciprocal final product plywood layer. If so, only experienced wood buyers can actually predict the quality of the end product. The inclusions, shoots and defects in the round material are often undetectable and thus cause defects in the plywood layer that cannot be further processed. Up to 85% material waste is produced in the plywood layer from round to final product, which is also acceptable in this process. A conventional subsequent process for making a complete surface is to assemble a plurality of plywood plies in an assembly plant or '-stacking factory" and to condition the surface of the assembled/stacked plywood layers. Typically, the assembly/stacking of plywood plies is accomplished by bonding individual ply plies, and in fact applying heat and pressure almost simultaneously using the so-called longitudinal and cross feed laminators. However, the 'hard-to-operate thin and sensitive plywood layer has been confirmed to be 112812.doc. It is noisy and can't make a line-type, thin straight-line layer, to achieve a proper bond. The plywood plies to be assembled shall have a maximum, J, and width. Furthermore, local application of heat can affect the properties of the wood (e.g., color), and excess glue must be removed in the bonded area. The resulting plywood layer can then be applied by bonding to a substrate, such as a sheet. The above process steps are included in the commonly known "European " or "North American Act" used to make plywood layers. In another technical method, commonly known as the Asian method, the unprocessed plywood layer is approximately (M mm to 〇.8 _ thickness. After the edge of the option is cut along the vertical:), < The wet plywood layer is applied to the substrate by bonding. The β-base material is usually a splint. Next, the customer purchases "fancy clips and cuts off the panel sections they want. This results in low throughput because the required dimensions do not exactly match the panel dimensions of the splint. This Asian style plywood layer manufacturing process requires an integrated process. The plywood layer after the slat/wood block is cut to have high humidity (the illusion at the fiber saturation point. Place the wood chip - the lower part will produce the mold layer of the mold and damage 7 can not be used. Long distance storage or transport It is not feasible. Only the plywood layer can be pressed onto the substrate. The product can be transported/treated. The value of the substrate is lower than that of the plywood layer. The plywood layer product is more economical than the fancy plywood product. This is especially important for increasing freight rates. Sex is only possible if the equipment can be made up to 45 pieces per minute of precision required to make these very thin plywood layers. 112812.doc 1327952 Furthermore, US 3,969,558 Uncovering the bonding of most of the short films of a wooden beam,

It can then be cut. Adhesives proposed in this patent, such as epoxy resins, phenolic resins, and resorcinol resins, are bonded. The goal of the 1;3 3,969,558 is to avoid the application of a heating/boiling process to the manufacture of a general plywood layer, and it is recommended to maintain the moisture of the wood permanently above the fiber saturation point throughout the process (iv). Furthermore, the patent suggests that there should be a heating and boiling process before cutting. Therefore, care must be taken during the entire process that the moisture of the wood is not reduced, nor is it short-term. Mostly, the plywood layer has a thickness between 〇π and ππη and a humidity greater than the saturation point of the wood fiber, which is overlaid and spotted onto a substrate. US 3,897,581 discloses the bonding of short beam-like wood chips and subsequent cutting, the bonding being carried out by applying a special polyurethane adhesive which also dries under this humidity.

No. 3,977,449 discloses a method for producing a plywood layer having a suitably designed wooden pattern of large area and mass production. In this method, the round material is ore-cut or cut into a plurality of strips which are smooth on the surface and adhered to the adhesive to form a composite strip. The composite strip 2 is then cut to form a wide plywood chip which can be bonded by an adhesive or a plywood layer. Throughout the process, all steps were carried out to maintain the humidity at or above the saturation point of the wood fiber. The moisture content of the resulting film laminate layer is also maintained at or above the fiber saturation point. / 〇 : ::: The manufacturing method of the slab layer, commonly known as the technical plywood layer ', white, when the plywood layer is manufactured, it should achieve a fixed quality and dimensional accuracy' to facilitate the prediction of the characteristics of the final product plywood layer . I128J2.doc 1327952 In this context, for example, previously prepared peeled plywood layers may be bonded to each other after pre-treatment such as dyeing or baking of the structure, and the resulting material may be subsequently cut. Here, the surface of a plywood layer can be produced to have a predetermined surface structure, and waste can be reduced. However, the resulting plywood surface cannot be compared to the plywood layer because the resulting end product has a hand-crafted aesthetic without a solid wood feel. At the same time, it is obvious that these methods are more complicated. SUMMARY OF THE INVENTION The present invention is based on the above problems to improve the method of manufacturing a conventional plywood layer, so that starting from the raw material wood initially used, the high-yield, high-quality final product plywood layer can be achieved with the lowest complexity. . Z. On the other hand, the method should be as simple as possible, and on the other hand, the further stepping of the resulting plywood layer should be beneficial to the user, for example, the furniture manufacturer. Furthermore, the beauty of the solid wood used should be maintained in the winning layer. In addition, it is standard equipment used in the European-style plywood manufacturing process, especially for cutters that allow more than 9-inch cutting speed per minute. This object can be solved by a method of manufacturing a plywood layer having an independent request and a device for implementing the method of claim 35. Furthermore, the solution of the second item comprises the manufacture of a beam-like block of the independent claim 29 for the manufacture-plywood layer and the independent request item 33 in accordance with the beam-like wood block of claim 3 or 32, respectively. Plywood layer. Particularly preferred embodiments of the invention are defined in the dependent claims. The wording of all the clear items is available for reference in this article. In the method of the present invention for producing a plywood layer, the plate-like planar wood 112812.doc 1327952 is first fully bonded by a glue/adhesive which is dried into a beam-like block under moisture. The wooden block is cut into a plywood layer along a defined section. According to the invention, the beam-shaped wood block is watered and/or warmed prior to cutting, and the watering and/or heating is preferably performed at a temperature rise. The implementation, preferably one is higher than the sensation, and the best is one at a temperature of 7 inches, especially 75 and 85. One of the temperatures between the 〇. Approximately 8 (TC temperature is most appropriate.

The watering and/or warming is preferably carried out for several days, especially for more than 2 days, especially 2 to 3 days. The plywood layer obtained by cutting (creating) the beam-shaped wood block is dried to reduce the humidity below the fiber saturation point of the wood. Preferably, the dry plywood layer has a humidity of 80% or less, preferably 6 % or less, more preferably less than or equal to N. In particular, the water content is below 2G%. An excellent plywood layer has a humidity between 5 and 20%. The saturation point of the fiber defines the wood that is free during the drying process.

The base "water only contains the point of "bonding" water. "Free radicals" water is located in the cell pocket of wood' and "bond" water is in the cell wall of wood. Humidity is based on DIN 52 183. Other methods can be used. You can use g1 g, 4_, J仗, for example, by electrical method (measurement of ohmic resistance value) or by infrared reflection.

The voice limiter recommends using the above DIN method as a calibration method to obtain comparable values. In a preferred embodiment of the invention, the method for making a plywood layer comprises the steps (1) to (iv): (!) using a binder to apply a plurality of plate-like planar shapes The wood chips are bonded into a beam 112812.doc 1327952 wood block, (u) the beam wood block is washed and/or warmed, (III) the beam wood block is cut into a plywood layer, (IV) The plywood layer obtained in step (in) is dried until its humidity is below the fiber saturation point. In the preferred embodiment, each of the cutters used in the step (in) is a spear.

A layer of plywood is obtained in step (iv), wherein a surface area is preferably from 1 to * m ', preferably from 1.5 to 3.5 m2. The preferred embodiment is substantially equivalent to the length of the block. The drying in the step (iv) is carried out at a temperature rise, and the 〇r ώ 乂 马 马 马 马 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 The drying is carried out immediately after the cutting in step (iii). In another preferred embodiment, the method further comprises the following steps (v)

To one or more of (VII): , J (V) before step (1): planing the plate-like planar shape A < at least one table; & @ (V1) before step (Η): Pressing the beam of wood; (vii) before step (v): stacking the beam of wood. The inventors have found that the method of the present invention can be used to 'pure a first-grade plywood layer. Advantageously, in this method, T is used in machines and devices that are commonly used. By requesting the feature of the feature of the ninth step, the cutting of the plywood layer is particularly smooth and the knife has a high quality 112812.doc 12, which can also be used for low thick sound A ^ BH ^ · 夕夕13 The slab is not broken. Here, in the context of the present invention, the basin η, you can maintain the humidity of the wood at the fiber saturation point (" private period between the entire system except the step (iv). In this way, the method of the present invention or the above, but not mandatory, such as the former technology simplification of the 'simultaneous', the method according to the invention of the ancient i σ @ ^ month 'plywood layer also has a Yurikou mouth quality and economy. By setting up the different brothers, the raw material wood-adhesive agent is dried and it is dried under the wetness of the brothers. Any number of wood chips is used. 1 is set without prior adjustment, you are like doing it in a dry room. Special, , ]

, ·,,, degree adjustment. By extension bonding, high quality and bonding of + & A I疋 can be produced without affecting the properties of the plywood layer (e.g., heating), and it is not necessary to remove excess glue in the joint zone. Furthermore, the 'plywood layer' can be produced in the same size as it is and can be adapted to subsequent processing' so waste can be minimized since trimming is no longer required. Last but not least, the method of this month also allows the manufacture of plywood layers of different structures, lines, thin, straight lines. Wood chips used herein as the starting material are commonly referred to as plates. However, for example, the respective thicknesses associated with the chips should not be limited as long as the length of the chips is greater than their thickness. This also applies to the beam-like blocks obtained in the practice of the method. Similarly, the size of each piece of wood should not be limited. Furthermore, it should be considered that in this paper the plywood layer is cut, not sawed or formed in a fiber removal (machining) process. This cutting is also often referred to as (four) cutting and forming a plywood layer with respect to the use of a tool, a knife or the like. In order to produce different surface patterns according to the invention, the wood block is cut along 112812.doc 13 1327952 into a plywood The cross section of the layer can be freely selected. The coupon is selected as h—the rotary section or the eccentric rotation method is applied to the section. The crane is used as the method of cutting along the direction, 4# &amp ; 丨β + Ρ + t is particularly perpendicular to a plane defined by the bond layer boundary. In addition or in addition, according to an embodiment of the invention, the face direction extends transversely to the fiber direction of the wood chip, in particular substantially: straight so that the cross section is preferably parallel to - including the longitudinal axis of the wood block The plane inside. Green • Widely, in the method of the present invention, any number of chips can be used. For example, the chips can be bonded to each other from different solid wood portions. However, the season of the wood chip is a solid board. These planks are typically cut sheets from different woods and are optionally flattened on one or two flat sides. As described above, the thickness or specification of the solid wood board is not critical to the method of the present invention. - Embodiments according to the present invention have proven to be particularly economical in that the plywood is a waste wood board produced during the manufacture of conventional plywood layers. This is commonly known as the "liner" coefficient millimeter thickness plate, but for technical reasons, the method is cut-stepped, although the plates are almost of high quality. This ruthenium print material can be easily used by the method of the present invention. The method of the invention is more advantageous if the material is from the center of the wood block because it is a high quality wood and in other processes it is possible to perform a suitable measurement on the generation of pith ray rays that are not present in the slab layer (eg Create a cut angle / section), otherwise it will reduce the economic value. / According to an embodiment of the present invention, 'the chips are separated from the center of the round material, or the round material is opened · · round wood", preferably at least three slaves, and some are not The advantage of using a round section is that the wood is still untreated on the basic 112812.doc 14 1327952, thus reducing the chance of material changes in subsequent processing 'eg soiling. Furthermore, the sections from the center of a round material are characterized by the special formation of pith ray rays in these sections, which is particularly evident in the conventional slab layer. In contrast, in the vane of the present invention, the semicircular section is cleaved - the central section of the round material can be made into a plywood layer by appropriate treatment with an appropriate cross section, wherein the pith beam is not easily seen or completely seen not see. In accordance with an embodiment of the present invention, preferably, the chips are substantially semi-circular segments that are separated from an edge region of a round material, preferably by splitting the round material into at least three segments. Basically, the semi-circular segments are bonded to each other on the side of the plane and subsequently cut 'preferably substantially parallel to the plane defined by the layers of adhesive. Fang &, 甘于.λ In this eight-series, one-piece, all-newness manufacturing process, in which the middle section of a round material is taken first and processed according to the above, and the edge sections of the other round material can be bonded to each other, so that the edge sections can be used It is known that the standard equipment of the plywood layer is manufactured with as little waste as possible. Preferably, in the method of the present invention, the chips used have a relatively high (relatively) wood moisture. This facilitates the subsequent cutting process in which the wood to be cut typically has a high wood moisture. Accordingly, the wood chips bonded in the method of the present invention particularly have a relative wood moisture at or above the fiber saturation point. The fiber saturation point is based on the type of wood. Change between. In this case, the wood is preferably a so-called unprocessed wood composition, i.e., a wood that has just been cut from unsaved trees, or a relatively short-lived storage. On average, this unprocessed wood has a relative humidity of about _. H2812.doc -15- ▲ In another method of the method of the present invention, the wood chips are spliced at a pole π H#' degree, for example, the high wood moisture can also be achieved by the water chips . In this case, we should assume a relative wood humidity of more than 5%, and Xiao is swimming. Between or with _ or even above. As described above, in the method of the present invention, the sheet-like planar chips are adhered to each other by an adhesive, preferably in a comprehensive manner. In this article, it is possible that the adhesive/adhesive needs to provide a solid solution between the bonded wood chips. Furthermore, as will be described later, the adhesive is subjected to the treatment of the wood block obtained by the bonding before the cutting (for example, watering treatment), and the treatment of the plywood layer obtained after the cutting (for example, drying treatment), finally, the adhesive needs to be used. Ensuring - reliable bonding 'for example if wood chips with a high wood moisture (wetting) are to be bonded to each other. Here, a series of adhesives are known, at least a part of which meets the above requirements and which results in a At least one satisfactory bonding. Particularly suitable for the method of the present invention is commonly known as a polyurethane adhesive, the adhesive can use a one-component adhesive and a two-component adhesive. Commonly known as hot polyurethane adhesive It is known that a one-component polyurethane adhesive is applied as a single product, so that the adhesive can be cured into a water-insoluble resin due to its inclusion isocyanate group, and the isocyanate group can be combined with Wood moisture and/or other polar groups contained in the wood. Two-component polyurethane adhesives are applied in two different compositions and are also cured by wood moisture. For example, commercially available one-component polyurethane adhesives Products for the Norwegian company's Prefere 6000 adhesive, or 112812.doc -16- Switzerland c〇Uan〇 Ag Company

Collano RP 2501. , Polyamide M agent (commonly known as heat-soluble), for example, by the German company, the eight systems are applied in the form of heat and need to be processed quickly. Similarly, oralization occurs by wood moisture and/or other polar groups contained in the wood. In the curing process, the hot sol is changed from a thermoplastic to a thermosetting property. In the present invention, it is particularly excellent in the heat generated. A single-component polyurethane having a nitrile sulphate content is disclosed in U.S. Patent No. 3,897,, the disclosure of which is incorporated herein by reference. Preferably, the sulphuric acid vinegar prepared by reacting a suitable polyethylene glycol with a suitable polyisocyanuric acid vinegar is applied. Preferably, the reaction is carried out in a manner such that the polyisocyanuric acid is metered in a residual amount to form a salt-producing ester group content in the polyurethane, which can be adjusted to the properties of the wood to be bonded. Claim. Preferably, the polyethylene glycol is a polyethylene glycol or a polypropylene glycol. In particular, the polyethylene glycol is polypropylene glycol. Preferably, the polyisocyanuric acid vinegar is selected from the group consisting of hexamethylene dinitrile acid, benzodimethyl diisocyanate vinegar, toluene diisocyanate vinegar, diphenyl ketone diisocyanate diethylate Diisocyanuric acid vinegar, hydrogenated diphenylmethane diisocyanuric acid, gasified bismuth diisocyanate, hydrogenated phthalyl diisocyanate, and β Λ in the group of mixtures and mixtures thereof Phenyl ketone diisocyanuric acid vinegar and / or hydrogenated diphenyl methyl bismuth succinic acid s: the reaction product with - polyethylene glycol is particularly preferred, especially with polypropylene glycol. If you use a polyurethane adhesive containing diphenylmethane diisocyanate, you can get the excellent properties of II28I2.doc •17· 1327952 propylene glycol reaction . In a preferred embodiment, the diphenylnonane diisocyanate comprises diphenyl sulfonium 4,4,diisonitrite and diphenylmethane 2,4,diisodecanoate One of the mixtures. Preferably, the polyisocyanate of the preferred embodiment may optionally comprise: an adjusted type of bismuth sulphuric acid vinegar, such as hydrogenated diphenyl carbaryl diisotrophic acid S曰 or the same guess, sour vinegar. Φ Preferably, the isocyanate content in the polyurethane is in the range of between 5 and 25% by weight, based on the total amount of the adhesive, preferably between 1 and 2%, especially Between 1 3 and 16.6%. The above polyurethane adhesive types from Dynea or CoUano are based on diphenylmethane diisocyanate. Unprocessed wood or other wood which can be used in the process of the invention and which is sawn into a flat sheet of wood can have a humidity of about 8%. When bonding a flat sheet of wood having such a high humidity, the water contained in the wood adversely affects the bonding properties of the specific type of adhesive/viscose and the short opening time of the specific adhesive. Here, the adhesive/viscose does not react in the desired manner - and the viscosity in the resulting beam-like wood block does not exhibit the desired stability. Some points cannot be accepted when the plywood layer is made of the beam-like wood block. The humidity of the plate-like wood chips to be bonded should be less than 5%, preferably less than 50%. Plate-like wood chips having a _ below peach moisture are particularly suitable for short opening times for specific types and specific viscosities in the method of the present invention. A beam-like block suitable for use in the method of the present invention can be formed, which comprises the following steps: Method H28\2.doc 1327952 (j) A plurality of plate-like planar chips are placed on the needle. ^ i The bonded surface is cooled to 0. (: one of the following temperatures, (jj) heating the waiting bonding surface to evaporate the water present in the surface region of the household in the wood, (j jj) will then adhere Applying the agent to the treated surfaces, (jv) bonding the plate-like planar wood chips into a beam-like wood block. Preferably, in step (j), the surfaces and the face are cold-coated to A temperature between 0 C and -1 o °c, preferably between -2 ° c and -6 ° C pq ^ U, especially between -2 ° C and -4 ° C. Preferably The cooling process is carried out in a cooling chamber. The heating in the step (jj) can be carried out by means of a radiation, preferably infrared radiation or UV radiation, but it is also possible to apply hot air. - In a preferred embodiment, the novel method for making a plywood layer comprises the steps (v) and (iv) (viii) prior to step (1) to cool a plurality of plate-like planar shapes that are too κ~ not to be bonded to the surface to be bonded. One temperature below 0 ° C, (ix) the waiting adhesion surface is ..., to evaporate the water present in the surface region of the wood. After the cutting, the beam-shaped wooden block of the _U should have a relatively high humidity. According to the present invention, the beam-shaped wooden block has a greater than the relative wood humidity before cutting. A greater than apparent relative wood moisture should be achieved; the relative wood moisture between 6G and 8G% is particularly advantageous. It is apparent that the plywood layer embodiment obtained in the method of the invention is not only capable of being selected during the cutting process. However, in the scope of the present invention, the conversion pattern of the plywood layer can also be varied by the type of mutual adhesion of the wood chips. Therefore, according to L: the preferred embodiment, the plate shape The flat-shaped wood chips are bonded to each other, and the fibers are substantially parallel to each other. By this bonding, the lowest complexity and the highest accuracy of the plywood layer can be produced, which has a - plate type " or " thick "Flat flooring material" in the form of a wooden flooring material, 5, which is particularly preferably wood or to >, and some of the wood chips are bonded to each other with their edges. In the context of the present invention, Bonding to each other, mixed shape = Therefore, according to the embodiment of the present invention, in the plate-like planar chevron pattern, some of the wood chips are made; the second = the inlaid floor. The fiber directions of the chips are mutually intersected and Visual effect. The father produces again - the lowest complexity of the pleasure of the wood according to the type defined in claim 15 ^ ^ ^. a invading this way to produce different L1 patterns of plywood layers. In this case, especially The method of producing a line pattern and a thin layer may be referred to as a plywood layer pattern, which is not produced by the prior art, and is % industrially inlaid.":: The method of the invention may be changed in a preferred manner. So that the difference is as follows;:: Into or into the wood block obtained by clicking the wood chips. For example, the top or bottom of the wood core sheet is disposed at least - different from the thin layer, for example, basically, in this context, it may be different from the wood material of the wood section or the like. However, in particular, such materials may be no. 112812.doc 1327952 is the same as wood (solid) flat sheet ’ 'like wood chips' which may also be referred to as ''plate shape'. Similarly, the foil 'sheets and sheets of such materials that are different from those of the wood can be incorporated into the combination of the slabs by bonding, so that the pieces of wood and the pieces of the material that are not in the wood are The configuration method and the sequence can be arbitrarily changed. In this way, the innovative plywood layer material can be produced. It is not only composed of wood, but also contains composite wood of one or the right and the same material as the wood: The sizing is also carried out in a comprehensive manner, that is, not only the wood sheets are integrally bonded to each other by an adhesive, but also the materials which are different from the wood and the adjacent wood are also completely bonded to each other. Here, usually the adhesive can be applied to wood/wood (four), such as the above agent. Preferably, the above-mentioned material different from wood is a metal or a metal alloy. On the other hand, preferably, any type (4) different from the (four) of the wood material should also mention 'particularly a polyolefin, for example, polypropylene or a copolymer containing the polyolefin. In other preferred embodiments of the method of the present invention, a colored adhesive or a dyed adhesive may be used as the adhesive. In the manufacture of the plywood layer invented by the party, it has been known that a new decorative effect can be achieved by utilizing the color of the adhesive. On the other hand, in this way, the color of the adhesive can be adapted to the color of the wood chips used and the color of the material sheets. Here, the adhesive layer is not different from the thin layer, and it will cause confusion. On the other hand, the color of the adhesive can be ^^ 4Λ _ ~ and from the color of the wood chips and the color of the material sheet different from the wood, in the finished plywood layer, by the comparison, j is learned in eight Can 112812.doc make: decorative effect. For this purpose, an optional 'thicker point' may be required for the technical function of bonding. According to the present invention, it is apparent that the color concept of the adhesive can be extended to materials different from those used for the sheet of material to be colored or dyed. Accordingly, the materials used herein are not limited to their "original" colors, so that a decorative effect can be achieved. As described above, basically, the thickness/size of the planar shaped wood chips to be used for sizing is not critical. The same applies to the thickness/size of a sheet of material different from wood and which is a composite of wood. However, for processing, a flat shaped piece of wood or a piece of planar shaped material other than wood has a thickness/size greater than 5 and is defined herein. In the range, especially the thickness/size between 5 mm and 120 mm should be defined. This is helpful for the current processing of woodworking machinery. Please refer to the text for the length and width of the wood chips or the material sheets different from wood. The description of the size of the block made of wood chips/flakes (and the above). Accordingly, the size of the block obtained in the process of gluing and the like is not critical, that is, it can be reasonable. It can be changed in a wide range. However, in the same way, the size of the wood block which is convenient to handle, that is, the cutting/cutting of the machine used in the manufacture of the general plywood layer can be selected. Accordingly, the beam-shaped wooden block of the method of the present invention preferably has A length of more than 1,500 mm, preferably more than 25 mm. A beam of up to 5 2 mm can be processed on a general cutting machine/cutting machine without any problem. In particular, each piece has A length of about 2,800 mm. Preferably, the width of the beam-like block is greater than 60 mm, preferably greater than 12 mm, and in particular a width of about 15 mm should be defined. Advantageously, the beam-like wood The height of the block is greater than 200 112812.doc -22- 1327952 is preferably greater than 500 mm. Beams having a height of mm can be treated. In particular, a height of about 600 mm is particularly preferred. Further, in the method of the present invention, Preferably, the plywood layer obtained after cutting/shaping is dried. Preferably, it is carried out at a temperature rise, particularly at a temperature varying between 70 C and 100. (depending on the type of wood. When a temperature rise is applied, in particular a temperature of more than 9 Torr, usually a drying time of several minutes is sufficient to provide a satisfactory drying of the resulting plywood layer. In this case, according to the invention, it is preferred that the drying is in the cutting. The process is carried out immediately after the process. The inventors have discovered that before sizing, The treatment of the respective bonding surfaces of the plate-like planar wood chips is of considerable importance within the scope of the invention. Due to the background, according to another embodiment of the invention, the bonding surface is planed before the gluing. By applying a rotary processing tool. On the one hand, the hunting is achieved by the flat surface of the adhesive surface, which is pleasing to the eye because the naked eye can not see the joint, and there is a tight and long-lasting connection between the pieces. / This is particularly advantageous if the axis of rotation of the rotary machining tool extends substantially perpendicular to the treated bonding surface. With this arrangement, the disadvantages of the conventional rotary bed machine are avoided. Yes, any shape of the bonding zone can be avoided 'and the honeycomb structure of the wood is not easily damaged, and its formation is particularly suitable for the open honeycomb structure of the application agent, thus actually creating an invisible joint. . Furthermore, this tool is also particularly suitable for wet wood. Last but not least, the arrangement of the rotary machining tool = axis is substantially perpendicular to the adhesive surface to be treated for removal, so that multi-pattern processing can be avoided, which results in high durability and work. The flatter surface of the piece.

In particular, as described in the method of the present invention 5 to provide a colored or dyed adhesive to achieve additional visual effects, the sheet of material different from the wood may be optionally colored. Or dyeing. 112812.doc • 24- For other preferred characteristics of the wood block of the present invention, please refer to the respective explanations herein above and reference is made thereto. Finally, the present invention also encompasses the plywood layer itself, which can be used from The method of the invention is taken from a beam-shaped block by cutting along a defined cross-section. For the nature of the plywood layer of the invention, reference is also made to the above description and is hereby incorporated by reference.π The method of the invention, the wood block according to the invention and the plywood layer according to the invention all have a series of special advantages. For the solution of the invention, the prior art method described above is reversed, so that The surface of the plywood layer is defined before cutting/cutting, and then only cutting/creating. It is only necessary or completely unnecessary to complete one of the assembly/stacking of the product. Therefore, one of the advantages is that it is not necessary Depending on the nature of the resulting plywood layer, and the plywood layers need not be trimmed to the usable range. By using a sheet of material having visible properties and qualities and/or by a different material than wood, with the cross section Optionally, the plywood layer pattern and plywood layer quality can be predetermined. Many other decorative effects can be achieved by application of a colored or dyed adhesive and by application of a colored or dyed material sheet other than wood. Since a plywood layer is in fact cut from a defined size of wood, a layer of wood plywood having a defined size can be produced. The wood plywood layer thus has a plywood layer of almost pre-defined quality and pre-defined dimensions; that is, it is a technical plywood layer that is aesthetically similar to the surface of a naturally laminated plywood layer. From this, the result is that the product can be supplied directly from the process for the end user of the plywood layer. Further processing (selection, cutting, assembly /

Il2812.doc •25· and the like) can be completely omitted or simplified to a considerable extent. - The plywood layer obtained from the method of the invention can be converted from a plywood layer, for example, it is particularly advantageous to apply a suitably assembled plywood ply to a piece of furniture. In this way, half of the work is done: . It is obvious that different plywood layer types (different wood, wood can be customized according to the pattern, colored or dyed adhesive) can be made and changed according to customer requirements. The combination of wood and wood (four), the innovative surface pattern and the aesthetics of the surrounding material are produced, so that the application of the wooden plywood layer provides a method for manufacturing the plywood layer. Method 'The device has the characteristics of request item 30 to Jane #1疋.

The above rt is based on the cutting blade of the rotating plane of the rotating solid body. [Embodiment] The above-mentioned characteristics and other characteristics of the present invention are derived from the description of the text and the claims after the text. Here, individual characteristics can be achieved by combining = alone. Λ 早 早 or mutual 1128I2.doc -26- 1327952 In the following, a preferred embodiment of the apparatus 3 for manufacturing a plywood layer according to the present invention is described with reference to FIG. The processing sequence of the drawings is illustrated by the dotted line with the arrow = the button - the appropriate transport device can be continuous or segmented (not shown). Thus, within the scope of the present invention, device 30 should not be required to provide all of the equipment shown in FIG. First, the device 30 has a table of coarse planing devices 6 〇 'plate-like planar chips. (4) Here, it is roughly removed by, for example, a planer or the like. The apparatus incorporates a selection device 61 and a rim processing unit 62 such that a skilled person is typically employed at the arranging equipment to select a work piece suitable for further processing from the conveyor board. Further, the device 30 has a wound bed device 63 for flattening each of the plate-like planes: at least one surface &, in this embodiment, the planer device 〇糸-rotating tool 63" It is shown in the figure " in a perspective view. As can be seen from Fig. 14, the rotary machining tool 63, the axis of rotation 63, extends substantially perpendicularly to the surface of the chip 1() to be treated. Thereby, the rotary cutter has a rotary solid body 'the solid body has a plurality of cutting edges = the cutting edges each have a cutting edge which is substantially parallel to the plane of rotation of the body. Within the scope of the present invention, for example, Le-dinek-: rDelmenWSt's "heart*, system, which can be used as a tool for processing, although it is understood that the invention is not limited thereto. The 63-bond-surface drying apparatus 64 is achieved in the present embodiment by a UV light, hot air or infrared light source device. The UV light or infrared radiation device is configured to pre-dry the surface of each of the chips 1H flat surface H2812.doc -27-1327952. Furthermore, the device 30 has an application device 65 for applying an adhesive or adhesive force to the planar shape of each of the chips and selectively pre-drying, cooling and reheating the surface, the adhesive application device 65 It can be set up in different ways, for example, the roll containing the adhesive or the like. However, if the device 65 for applying the adhesive has a plurality of nozzles (not shown) for application Stickiness is more beneficial. • + Subsequent 'device 3' contains a stack of 66' so that the chips with the adhesive become a beam of wood. Here, for example, it may be a platform having a ring or the like. The stacking device 66 incorporates a pressing device 67 for each of the clamshells. The pressing apparatus can be operated with a liquid weight, for example, it can be designed as a rotary table or a line-type factory: a pressing device 67 in combination with an adjusting device 68 for washing and/or warming the pressed beam-shaped block. Adjustment device 68 can be, for example, a heated pool or a steam pool. • The device 68 is followed by a planer device 69 (slat planer) for smoothing one side of the beam-like block to facilitate its proper installation on the planing device 70. The apparatus 69 incorporates a cutting device 70 (plywood layer cutter) for cutting/shaping each of the pressed beam-shaped blocks into a plywood layer. Thereby, the cutting/creating device 70 can be designed in different ways' for example it can be used for a horizontal or vertical planing, for rotary planing or for eccentric rotary cutting. A drying device 71 is mounted downstream of the cutting/slicing apparatus, for example having a flow chamber through which hot air passes. 112812.doc -28 - Finally, in "18.1 to 18.3, the method of the invention is compared to the method of the invention shown in Figures i91 to 19.2. In the conventional method of Fig. 18, 1, a round material 50 is formed by a peeling machine 58 into a pair of skins, for example, by a band saw 59, which is cut in the longitudinal direction, and the two halves are also in water. The water is again supplied (adjustment device 68) and then passed through a planer device 69. The second half of the round is then cut. In Figures 191 to 192 of the method according to the invention, the wood board is planed from a bed and is preferably 63 (preferably using a planer from R〇t〇les). The resulting plate-like planar wood chip 10 is then passed through a surface drying apparatus 64 (e.g., UV, hot air or infrared radiation) and an application device 65 for application to the adhesive 2 . The plate-like planar wood chips having the adhesion agent are stacked in the stacking device 66 and pressed into one or more beam-like blocks 12 in the pressing device 67. Thereafter, the beam-like block is poured into an adjustment device 68 (e.g., a water tank) for 6 weeks to correct the correct humidity, and then planed with a planer 69 and cut into a plywood layer 14 in the planing device 70. The method for producing a plywood layer according to the method of the present invention after drying in the drying apparatus 71 is completed. Alternatively, the finished plywood layer can be trimmed in the longitudinal and/or transverse directions 74, 75 and processed by assembly 79. The new method changes the European style of plywood layer manufacturing, so for all surface patterns of planks, such as the appearance of wood, subsequent manufacturing steps (cutting/dressing of plywood layers and laborious assembly/stacking processes) It becomes old fashioned. At the same time, 'it doesn't need to be like the Asian style method. The surface of the plywood layer will be used and pressed immediately, because the plywood layer has been dried to - standard humidity (8-16% humidity) ^ dry the plywood layer to a low humidity 1128l2.doc •29· The surface of the H wooden surface is applied. It can be transported and stored before the __ substrate. In the new method of the present invention, there is no fight, always by survey and/or in the open market P "the wood of different humidity can be opened in the standard wood and the sawing under the standard wood / just saw the button / rose The inch is mixed with the same process, the wood raft / strip wood. In addition, 乂 will be different types (and use - the production of the slab layer can also be abundance of adhesives) while using the standard plywood layer to create a cut / drowning / adding and then stepping on the private π, 匕栝 ... and follow-up New Zealand process), and have a look at the new method to study the system, the birth of π brothers. _ ° ^The plywood layer that can be transported and stored, while providing a product that is significantly less expensive to manufacture than conventional methods. The other advantages of the new method are that the material layer pattern and the plywood layer size are selected before the cutting and the f is dried to obtain the modified wooden shell surface, and no other treatment is required before being applied to the substrate. . By the mixing of the steps of the method of the present invention, the limitation of the technique is limited. The heart of the (4) method can overcome the prior art and at the same time economically, the new method has a significant advantage. The total manufacturing cost including the raw material cost is at least 20% lower than the standard method (European style method). It provides the cutting quality that cannot be achieved without adjustment. The main shame has been greatly improved. Each stroke of the cutter produces approximately Dm's marketable product' instead of the traditional method. The cutting machine & gate f - up to five times. The cutting and drying equipment is obviously the most expensive, so the most important equipment from the forest to the entire manufacturing chain that makes up the furniture is used in the most efficient way. Since standard unprocessed wood can be used, the output from the high-efficiency hardwood industry can be used as a raw material, which is a significant increase in potential use of the plywood layer when used. I12812.doc -30· 1327952 source. In addition, the present invention can use the chopped and wood sizes that are less commonly used in the wood industry, thereby converting the waste into a high value decorative product. The most important advantage is that a real wood surface can be produced in a cost-per-square fashion, again competing with other alternative surface materials such as low-pressure memantine, high-pressure beauty and others. This is a major breakthrough in the surface material industry. The invention will be exemplified in the text. 1. EXAMPLES The operation of the apparatus of the present invention is more specifically a first preferred embodiment of the method of the present invention, and the product of the present invention will be described later with reference to Figs. 3, 4 and 13. First, provide a wooden board that has just been sawn from oak or beech wood, and its size (length X width X height) is 2,400 _ X 150 _ χ 1〇〇. The planks may be planed in the apparatus 60 for roughing the subsequent bonding surfaces and then picking them, for example by manual or selective equipment 61. Subsequently, the edge is implemented in a separate device 62, and the subsequent bonding surfaces are all planed in the planer device 63. Depending on the desired opening time of the adhesive, the subsequent bonding surface of the board can now be selectively applied within the surface drying apparatus 64 prior to application of an adhesive 2 to the bonding surface in the apparatus 65. The surface is pre-dried. For this reason, Dynea's prefere 6〇〇〇 product can be used as an adhesive. Here, it is a one-component polyurethane adhesive for wood structure, which has a polyurethane-based adhesive. For the manufacture of an adhesive, the adhesive is applied to the respective bonding surfaces of the boards. On one side. In this regard, a small piece of bamboo or a parent can be used at the nozzle. The applied dose of 112812.doc -31 · 1327952 is about 25 〇 g/m2 per wood surface. Subsequently, six pieces of wood boards 10 are stacked in a stacking device 66 into a beam-like wood block (produced in length x width: X: 400 mm X 150 mm X 600 mm), and are bonded to each other. Next, the drying of the adhesive is carried out in the pressing device 67, in this case, an approx! The N/mm2 pressure was applied for a pressing time of about 8 hours. The beam-like blocks 12 obtained from the bonded solid wood panels are - sufficiently rigid for subsequent processing steps. Subsequently, in the adjusting device 68, the bonded beam-like wood block is heated in water at a temperature of about 8 ° C for about 2.5 days, and then cut into a plywood layer 14 having a thickness of about 65 melons. Next, the cutting/shaping plane is selected to be perpendicular to the plane defined by the bonding layer 20, actually in the longitudinal direction of the wood block, thus producing a plywood layer having a width of 600 mm and a length of 2,400 mm. Here, the cutting direction is transverse to the wood fibers. The resulting plywood layer 14 is at about 140. (: The temperature is directly dried and dried for about 60 seconds. 2. Embodiments Hereinafter, the second embodiment of the method of the present invention or the product of the present invention will be described with reference to Figs. 1, 2 and 13. In principle, the first The second embodiment corresponds to the above method, but 'in this second embodiment, an oak (solid wood) scrap board (liner) which produces a thickness of 13 mm and a humidity of about 65% from the plywood layer is not Provided for extended storage time for the manufacture of the wooden block of the invention. Here, the 'individual wood board is cut into a fixed size of 2,4〇〇mm X 15〇mm in the lateral direction and the front side. 12 pieces of wood are provided for obtaining this. Invented wood block 12 112812.doc • 32- 1327952 required 13⁄4 degrees 1 5 6 mni. On the surface of the board - moderately created, on one side, an adhesive / adhesive 20 is made of - long strips Formally applied and applied with Lame U's adhesive (device LK5PUR). The adhesive used was a one-component polyurethane adhesive of & (10) 〇 AG, and the treatment time (opening time) was about 7 minutes. The adhesive contains diphenylmethyl diisocyanate, which is the opposite of polypropylene glycol. The product is applied the adhesive is about 15〇.

Immediately after the sizing, the formed wood block 12 was pressed in a press apparatus crucible at a pressure of 〇 8 N/mm for 6 hours. After the subsequent 12-hour stop time, the two wooden blocks formed are in the water bath of the large (four) t temperature for another hour (Luoqi). The chilled wood block 12 is then cut into a 〇 65 mm thickness (i.e., perpendicular to the longitudinal direction of the bonding plane) in a plywood layer cutting/creating device. The plywood layer 14 obtained from the plywood layer 14' is dried to a relative humidity of about 8% in a dry slap called temperature.

The resulting material, i.e., a technical plywood layer, has an appropriate plywood layer of suitable quality and which is distinguished from a commercially available long longitudinal structure, i.e., a strip of plywood. It can then be applied to a suitable substrate, such as a wood panel, using different bonding methods. For technical reasons, in the treatment of general plywood layers, it is not possible to assemble some of the purlin ply layers, and the aesthetics within the plywood layers can only be achieved by the method of the present invention. 1· Transformation type ^JS. ΊΓ". The beech wood begins, the method of the first embodiment is carried out, in which all <5 y , n. month beech wood boards are adhered to the 500 mm height wood 112812.doc of the present invention. 33- 1327952 block. The fixed-scale temple of the wooden boards is the same as the wooden board 10 of the first embodiment in the + size. After cutting, a technical plywood layer is obtained as a good horse material. The beauty is as simple as the simple assembly/stacking. Noisy on the surface of the board. For example, the enamel plywood layer is used for door panels or for furniture Ml 2. The transformation type is made of walnut and maple wood - the lining of the plywood layer has a thickness of 14 mm, and according to the second sinus The method of preparation, planing, optional cleaning and subsequent gluing. In the gluing step, the first three pieces are made of maple wood, one piece is made of walnut wood, the pile foundation is 丄, ^ ^ is the connector, three pieces are made of maple wood, and the piece is made of walnut wood and finally. 3 pieces of maple wood into the agricultural wind are all glued to the other. By the bonding of the 11 plates, a piece of height 154 mm is generated. Therefore, the wood of walnut and maple is awkward, and β is particularly good. Because maple and walnut have similar drying coefficients, the layer composition of the sister U is not easy to delaminate or crack. The technical plywood layer obtained according to this transformation pattern is aesthetically similar to a laminate bonded by a different material. Because in the manufacture of conventional plywood layers, these narrow strip plywood layers cannot be bonded for technical reasons, the aesthetics within the plywood layer can only be achieved by the method of the present invention. 3. The conversion pattern is in the conversion pattern, which is carried out according to the second embodiment. However, instead of the sixth layer of the oak board, a thin aluminum plate (thickness 〇8) is incorporated into the layer composition and is adhered. The composition is fixed by glue. In this way, it is conceivable to obtain a (wood) block of a height range of 3]_. The resultant may be a (4) JJ2812.doc -34- 1327952 plywood layer, in particular its aesthetics may be - a strong % longitudinal orientation (optical characteristics in the longitudinal direction) due to aluminum embedding. This conversion pattern has not been implemented. 3. Embodiments A third embodiment of the present invention will be described later with reference to Figs. In this embodiment ' it starts from approximately 2,800 mm X 150 mm X 60 mm ruler

The oak board is obtained by bonding a shorter oak sheet 10 which is a freshly sawn unprocessed wood and which is bonded to the end by a polyurethane adhesive (Dynea & prefere product). The resulting oak panel 10 was planed on both sides to a final thickness of 5 jaws and further processed in accordance with the method of the first or second embodiment. A beam-like block 12 having a height of 300 mm is provided in accordance with the present invention, whereby the oak sheets 10 of the sheet are bonded to each other. Next, cutting/cutting is carried out as described in the first or second embodiment.

With regard to its surface, the resulting material 'is a technical plywood layer 14 which is similar to the typical floor arrangement of an oak parquet floor. 4. Embodiments The fourth embodiment of the present invention will be described later with reference to Fig. (1). The feature of this embodiment is that the board 10 is bonded into a beam-like block 12 in a sub-shaped pattern, as shown in Figs. 8 and 9, where the adjacent boards 10 are respectively at their side surfaces. They are bonded to each other, and the front faces of the wooden boards are also adhered to the sides of the adjacent wooden boards 10. Then, as described in the first yoke, the yoke is pressed, turned, and sliced. 112812.doc -35- 1327952 5.
