- each stack aiming to secure by bonding the superimposed plates, and therefore the adjacent lamellae of the material obtained by cutting slices, according to the arrangements which have been explained above, is in any event less than the crushing of the fibers of the wood used (therefore, variable with the density of the species of wood) and is carried out at a temperature between room temperature and 120 ° C, and even more, according to the techniques used, although the values are a function of the type of glue used.
- the colored glue joints can be of the same color or of different colors, distributed among the different joints and even in the same joint, depending on the desired aesthetic effects, and produced from a rigid or flexible adhesive; in the case where the adhesive is flexible, it may be of the expanded type.
- ribs when the ribs are attached, they can be made, not only of wood, but also of cardboard or based on non-compressible synthetic or natural material (s).
- the depth of the recesses 25a is essentially limited by the resistance properties of the lamellae which are fitted with them.
- the thickness of the wooden strips can vary within a relatively wide range of values, for example between 1.5 and 100 mm and even more depending on the needs and the intended applications.
- the lower limit (not included in the range of values) for the thickness of the joint 3 of colored glue is constituted by the small thickness of glue which is applied to the ribs 5 and which remains after pressing the stack, of the order of 0.01 mm.

Description
La présente invention est relative à un procédé de fabrication d'un matériau en bois du type à coloration intégrée, ainsi qu'au matériau ainsi obtenu.The present invention relates to a method for manufacturing a wooden material of the integrated coloring type, as well as to the material thus obtained.
Un matériau en bois à coloration intégrée est constitué d'une pluralité de lamelles en bois adjacentes et séparées entre elles sur toute leur hauteur et sur toute leur longueur par une substance colorée, en matière synthétique ou naturelle, faisant fonction de colle et solidarisant les lamelles précitées entre elles.A wood material with integrated coloring consists of a plurality of adjacent wooden strips and separated from each other over their entire height and over their entire length by a colored substance, of synthetic or natural material, acting as an adhesive and securing the strips mentioned above.
Un matériau de ce type est déjà connu dans la technique depuis bien longtemps, comme le montre le Brevet US-2 062 590.A material of this type has been known in the art for a long time, as shown in US Patent 2,062,590.
Toutefois, jusqu'à présent, on a été incapable de maîtriser l'uniformité de l'épaisseur du joint de colle colorée entre lamelles, en sorte que l'épaisseur du joint coloré correspond à la mince pellicule de colle qui reste après serrage sous pression des plaques collées entre elles et à partir desquelles on obtient le matériau précité.However, until now, we have been unable to control the uniformity of the thickness of the colored glue joint between lamellae, so that the thickness of the colored joint corresponds to the thin film of glue which remains after tightening under pressure. plates bonded together and from which the above material is obtained.
La présente invention s'est donc donné pour but de pourvoir à un procédé de fabrication d'un matériau en bois du type précité, qui répond mieux aux nécessités de la technique que les matériaux du même type, visant au même but, antérieurement connus, notamment en ce que:
- l'épaisseur du joint de colle est susceptible de varier dans une plage de valeurs relativement étendues, tout en restant uniforme sur toute la longueur des lamelles qu'il solidarise entre elles,
- le coût de production est très fortement diminué du fait de la possibilité de contrôle de la quantité de colle à utiliser,
- les moyens mis en oeuvre pour réaliser l'invention permettent de rendre le matériau en bois également apte à exercer une fonction d'isolation sonore et/ou thermique,
- le matériau est susceptible d'adaptation à des surfaces galbées et d'absorber les dilatations et les rétractions du bois,dont il est composé , qui sont dues aux variations hygrométriques et thermiques, et ce sans se déformer et donc sans affecter l'effet décoratif recherché.The aim of the present invention is therefore to provide a method for manufacturing a wooden material of the aforementioned type, which better meets the requirements of the technique than materials of the same type, aiming at the same aim, previously known, in particular in that:
the thickness of the adhesive joint is liable to vary within a relatively wide range of values, while remaining uniform over the entire length of the strips which it fixes together,
- the production cost is very greatly reduced due to the possibility of controlling the quantity of glue to be used,
the means used to carry out the invention make it possible to make the wooden material also capable of exercising a sound and / or thermal insulation function,
- the material can be adapted to surfaces curved and absorb the expansions and retractions of the wood, of which it is composed, which are due to hygrometric and thermal variations, and this without deforming and therefore without affecting the desired decorative effect.
La présente invention a pour objet un procédé de fabrication d'un matériau constitué d'une pluralité de lamelles en bois adjacentes séparées entre elles sur toute leur hauteur et sur toute leur longueur par un joint de colle colorée solidarisant les lamelles entre elles, lequel procédé comprend les opérations suivantes :
- superposition d'une pluralité de plaques en bois après avoir étalé une couche de colle colorée sur au moins une face de chaque plaque,
- pressage de l'empilage ainsi obtenu,
- découpage de cet empilage, de préférence perpendiculairement au plan défini par celui-ci, en tranches dont la largeur correspond à la hauteur des lamelles, de façon à obtenir le matériau précité,
et est caractérisé en ce que l'on pourvoit chacune des plaques de l'empilage précité, sur au moins une face de celles-ci, de moyens permettant d'obtenir une épaisseur de colle colorée entre plaques superposées de l'empilage susdit, et donc une épaisseur du joint entre lamelles adjacentes du matériau précité, qui présente une valeur prédéterminée variable dans une plage appropriée, et qui est uniforme sur toute la longueur des plaques, et donc des lamelles.The present invention relates to a method of manufacturing a material consisting of a plurality of adjacent wooden strips separated from each other over their entire height and over their entire length by a colored glue joint securing the strips together, which method includes the following operations:
- superimposition of a plurality of wooden plates after having spread a layer of colored glue on at least one face of each plate,
- pressing of the stack thus obtained,
- cutting of this stack, preferably perpendicular to the plane defined by it, in slices whose width corresponds to the height of the lamellae, so as to obtain the aforementioned material,
and is characterized in that each of the plates of the aforementioned stack is provided, on at least one face thereof, with means making it possible to obtain a thickness of colored adhesive between superposed plates of the above-mentioned stack, and therefore a thickness of the joint between adjacent lamellae of the aforementioned material, which has a predetermined value varying within an appropriate range, and which is uniform over the entire length of the plates, and therefore of the lamellae.
Selon un premier mode de mise en oeuvre préféré du procédé selon l'invention, les moyens précités sont constitués par au moins une pluralité de nervures longitudinales espacées entre elles, dont la hauteur est fonction de l'effet esthétique et/ou de l'économie de colle recherchés, à savoir de l'épaisseur du joint de colle colorée entre lamelles adjacentes, chaque couche de colle colorée étant étalée sur les nervures précitées et dans les rainures séparant deux nervures adjacentes.According to a first preferred embodiment of the method according to the invention, the aforementioned means consist of at least a plurality of longitudinal ribs spaced apart, the height of which depends on the aesthetic effect and / or the economy of glue sought, namely the thickness of the colored glue joint between adjacent lamellae, each layer of colored glue being spread over the aforementioned ribs and in the grooves separating two adjacent ribs.
Selon une disposition préférée de ce premier mode de mise en oeuvre, dans les rainures séparant deux nervures adjacentes sont ménagées des évidements plus profonds communiquant avec les rainures correspondantes et destinés à être remplis par une matière adhésive ayant également des propriétés d'isolation acoustique et/ou thermique.According to a preferred arrangement of this first embodiment, in the grooves separating two adjacent ribs are provided deeper recesses communicating with the corresponding grooves and intended to be filled with an adhesive material also having sound insulation properties and / or thermal.
Selon une modalité préférée de ce premier mode de mise en oeuvre et de cette disposition, chaque découpage en tranches est effectué de manière à supprimer les nervures et à inclure essentiellement une rainure ou gorge séparant deux nervures adjacentes, les nervures étant relativement étroites par rapport aux rainures ou gorges qui les séparent. De façon plus précise, lorsque les nervures sont supprimées lors du découpage, elles présentent une largeur qui est obligatoirement inférieure à la largeur de l'élément coupant de l'outil de coupe utilisé (notamment constitué par une scie circulaire).According to a preferred embodiment of this first embodiment and of this arrangement, each slicing is carried out so as to remove the ribs and to essentially include a groove or groove separating two adjacent ribs, the ribs being relatively narrow compared to the grooves or grooves between them. More precisely, when the ribs are removed during cutting, they have a width which is necessarily less than the width of the cutting element of the cutting tool used (in particular constituted by a circular saw).
Selon une autre disposition avantageuse de ce premier mode de mise en oeuvre, chaque plaque comporte une première et une deuxième pluralité de nervures de largeurs différentes, chaque nervure de la première pluralité étant séparée, de part et d'autre, par deux rainures ayant la même profondeur ou des profondeurs différentes et séparant, conjointement, chaque nervure de ladite première pluralité de deux nervures de ladite deuxième pluralité.According to another advantageous arrangement of this first embodiment, each plate comprises first and second plurality of ribs of different widths, each rib of the first plurality being separated on either side by two grooves having the same depth or different depths and jointly separating each rib of said first plurality of two ribs of said second plurality.
Selon une modalité avantageuse de cette disposition, chaque découpage en tranches est effectué de manière à inclure essentiellement une nervure, appartenant à l'une desdites première ou deuxième pluralités et avant la largeur la plus grande, ainsi que les rainures qui la délimitent,tout en supprimant les nervures de largeur moindre.According to an advantageous modality of this arrangement, each slicing is carried out so as to essentially include a rib, belonging to one of said first or second pluralities and before the widest width, as well as the grooves which delimit it, while removing the narrower ribs.
Selon encore une autre disposition avantageuse de ce premier mode de mise en oeuvre, chaque plaque comporte une seule pluralité de nervures séparées par des rainures.According to yet another advantageous arrangement of this first embodiment, each plate has a single plurality of ribs separated by grooves.
Selon une modalité avantageuse de cette disposition, chaque découpage en tranches est effectué de manière à inclure essentiellement une nervure et une rainure.According to an advantageous modality of this arrangement, each slicing is carried out so as to essentially include a rib and a groove.
Conformément à l'invention, les nervures précitées sont continues ou discontinues sur toute la longueur des plaques.According to the invention, the aforementioned ribs are continuous or discontinuous over the entire length of the plates.
Egalement conformément à l'invention, lesdites nervures peuvent être réalisées d'un seul tenant avec la plaque qui les porte ou rapportées sur celle-ci.Also according to the invention, said ribs can be made in one piece with the plate which carries them or attached to it.
Encore également conformément à l'invention, le découpage par tranches longitudinales de l'empilage des plaques superposées et collées entre elles est effectué de manière à ce que chaque tranche comprenne, au moins en partie, lesdits moyens ayant servi à définir l'épaisseur de colle colorée et à en assurer l'uniformité sur toute la longueur, et ce notamment pour des raisons d'économie de colle colorée et/ou d'effet esthétique recherché. Le découpage peut être aussi effectué de manière à exclure ces moyens.Still also in accordance with the invention, the cutting into longitudinal slices of the stack of superimposed plates glued together is carried out so that each slice comprises, at least in part, said means having served to define the thickness of colored glue and ensuring its uniformity over the entire length, in particular for reasons of economy of colored glue and / or desired aesthetic effect. The cutting can also be carried out so as to exclude these means.
Outre les dispositions qui précèdent, l'invention comprend encore d'autres dispositions, qui ressortiront de la description qui va suivre.In addition to the foregoing provisions, the invention also comprises other provisions, which will emerge from the description which follows.
L'invention sera mieux comprise à l'aide du complément de description qui va suivre, qui se réfère aux dessins annexés dans lesquels :
- la figure 1 représente un empilage de plaques superposées comportant chacune un premier type de moyens selon l'invention ;

La figure 1 illustre un empilage 1 de plaques en bois 2a, 2b, ... superposées l'une sur l'autre et solidarisées entre elles par une substance colorée 3 faisant fonction de colle (par exemple, une colle époxy colorée dans sa masse par des pates pigmentaires aqueuses).Figure 1 illustrates a stack 1 of
Chacune des plaques en bois est usinée de manière à comporter des nervures 5 (équidistantes dans le cas de la figure 1) ; il est facile de vérifier que ces nervures, de hauteur uniforme, constituent un moyen efficace pour que l'épaisseur de la couche de colle colorée 3 ait une valeur désirée (lorsque celle-ci est appliquée dans les espaces 4 séparant deux nervures adjacentes 5 et sur ces mêmes nervures),en principe variable dans une plage relativement étendue pouvant dépasser 3 mm et même plus, tout en assurant l'uniformité de cette épaisseur sur toute la longueur des plaques.Each of the wooden plates is machined so as to have ribs 5 (equidistant in the case of FIG. 1); it is easy to verify that these ribs, of uniform height, constitute an effective means so that the thickness of the layer of
Le matériau en bois obtenu à partir de l'empilage 1 de la figure 1 par découpage de tranches A-B,à savoir comprises entre les plans A et B, définis par les axes x-x′ et y-y′, est illustré à la figure 2 par la référence 14. Ces axes correspondent aux axes de l'élément coupant de l'outil de coupe, dont la largeur est supérieure à celle des nervures 5, qui sont donc supprimées lors du découpage, de façon à laisser apparaître, de part et d'autre des lignes de coupe, la substance colorée 3 sur les deux faces principales de l'élément 14. Ce dernier est formé d'une pluralité de lamelles 2′a, 2′b,... (5 dans le cas représenté à la figure 2) qui sont solidarisées entre elles par des joints 3 de colle colorée, dont l'épaisseur a la valeur désirée, qui est égale à la hauteur 3a des nervures 5 augmentée de la faible épaisseur 3b de colle appliquée sur ces nervures et restant après compression de l'empilage (visant à solidariser, par collage, les plaques superposées) et qui est sensiblement uniforme sur toute la longueur de l'élément 14. Le découpage de celui-ci se fait dans le sens du lignage, par tous moyens appropriés, par exemple à la scie circulaire ou à la scie à ruban.The wooden material obtained from the stack 1 of Figure 1 by cutting slices AB, namely between the planes A and B, defined by the axes xx ′ and yy ′, is illustrated in Figure 2 by the
La figure 3 illustre une variante de réalisation du procédé selon l'invention. Dans ce cas, les moyens visant à donner à l'épaisseur de colle entre lamelles adjacentes la valeur désirée et à la rendre uniforme sur toute leur longueur sont constitués par une pluralité de nervures 8 de hauteur uniforme, obtenues par usinage sur une des faces desplaques 6a, 6b,... dont se compose l'empilage 10. Une couche de colle colorée est appliquée entre deux plaques superposées de manière à remplir les rainures 7 séparant deux nervures consécutives et à s'appliquer sur ces nervures (ou méplats) 8.FIG. 3 illustrates an alternative embodiment of the method according to the invention. In this case, the means intended to give the thickness of glue between adjacent lamellae the desired value and to make it uniform over their entire length are constituted by a plurality of ribs 8 of uniform height, obtained by machining on one of the sides of the plates. 6a, 6b, ... which makes up the
Le découpage de l'empilage 10 par tranches selon les plans A et B, définis par les axes x-x′ et y-y′, permet d'obtenir l'élément 15 illustré à la figure 4 constitué par des lamelles adjacentes 6′a, 6′b séparées par des joints 9 de colle colorée,dont l'épaisseur est différente sur les deux faces principales de l'élément 15, tout en étant uniforme sur chacune de ces faces.Cutting the
Sur la face supérieure de l'élément 15, l'épaisseur du joint 9 est égale à la profondeur 9a des rainures 7 augmentée de la faible épaisseur 9b de colle qui est appliquée sur les espaces (nervures) séparant deux rainures adjacentes et qui reste après compression de l'empilage 10, alors que sur la face inférieure l'épaisseur du joint est constituée par cette faible valeur précitée 9b. Bien entendu, dans ce cas,seulement la face supérieure est destinée à être exposée.On the upper face of the
Il est en outre facile de vérifier que le mode de mise en oeuvre du procédé correspondant à la figure 3 correspond à la solution la plus économique en ce qui concerne la quantité de colle colorée à employer.It is also easy to verify that the mode of implementation of the method corresponding to FIG. 3 corresponds to the most economical solution as regards the quantity of colored glue to be used.
Un autre exemple de mise en oeuvre du procédé selon l'invention est illustré à la figure 5. Ici, les moyens précités, visant à obtenir des joints de colle colorée entre lamelles adjacentes qui aient une épaisseur donnée uniforme sur toute leur longueur,sont constitués par une première pluralité de nervures 12 et une deuxième pluralité de nervures (ou méplats) 13, les nervures de la première pluralité étant disposées alternativement avec les nervures de la deuxième pluralité et ayant une largeur moindre que celle de ces dernières. La couche de colle colorée appliquée entre deux plaques superposées 11a, 11b, ... remplit donc les deux pluralités de rainures 17 et 18,de profondeurs différentes, séparant deux nervures 12, 13 adjacentes de largeurs différentes et se trouve appliquée sur ces nervures. Le découpage de l'empilage 20 illustré à la figure 5 suivant les plans A-B, définis par les axes x-x′ et y-y′, permet d'obtenir l'élément 16 constitué par des lamelles 11′a, 11′b, ... et des joints 19 de colle colorée présentant sur les deux faces principales de l'élément 16 une épaisseur différente, tout en étant uniforme sur chacune de ces faces.Another example of implementation of the method according to the invention is illustrated in FIG. 5. Here, the aforementioned means, aimed at obtaining joints of colored glue between adjacent lamellae which have a given uniform thickness over their entire length, are formed by a first plurality of ribs 12 and a second plurality of ribs (or flats) 13, the ribs of the first plurality being arranged alternately with the ribs of the second plurality and having a width less than that of the latter. The layer of colored glue applied between two
Sur les faces supérieure et inférieure de l'élément 16, l'épaisseur du joint 19 est égale à la profondeur 19a et 19c des rainures 18 et 17, respectivement, augmentée de la faible épaisseur 19b de colle qui est appliquée sur les nervures 12 et 13, séparées par les rainures 17 et 18,et qui reste après compression de l'empilage 20. Entre les deux portions 19a et 19c du joint 19, celui-ci présente une épaisseur ayant la faible valeur précitée 19b.On the upper and lower faces of the
La solution illustrée à la figure 6 permet d'exposer l'une ou l'autre des faces principales de cet élément, selon l'effet esthétique désiré.The solution illustrated in Figure 6 allows to expose one or the other of the main faces of this element, depending on the desired aesthetic effect.
L'épaisseur du joint de colle qui apparaît sur la face supérieure de l'élément 15 de la figure 4 et sur les faces supérieure et inférieure de l'élément 16 de la figure 6 varie dans une plage de valeur relativement étendue qui peut dépasser 50 mm et même plus.The thickness of the adhesive joint which appears on the upper face of the
Encore un autre exemple de mise en oeuvre du procédé selon l'invention est illustré à la figure 7 où, sur chaque plaque, est ménagée une pluralité de nervures 22 séparées par une pluralité de gorges 25 à profil composite, notamment en forme de Ω inversé, qui sont remplies d'une substance adhésive 27 ayant aussi des propriétés isolantes du point de vue acoustique et/ou thermique, notamment constituée par du polyuréthanne souple.Yet another example of implementation of the method according to the invention is illustrated in FIG. 7 where, on each plate, a plurality of
Les gorges à profil composite 25 comportent une portion plus profonde 25a délimitée, de part et d'autre, par deux portions moins profondes 25c.The grooves with
Bien entendu, lors de l'application de la colle colorée sur chaque face des plaques 21a, 21b, ... de l'empilage correspondant 30 de la figure 7, celle-ci remplit les gorges 25. Une pellicule de colle se trouve appliquée également sur les nervures 22 séparant ces gorges, en sorte que, par découpage de l'empilage 30 selon les plans A, B, définis par les axes x-x′ et y-y′, on obtient l'élément 23 illustré à la figure 8, constitué de lamelles 21′a, 21′b séparées par des joints 24 ayant l'épaisseur voulue 24c sur les deux faces principales de l'élément 23 (égale à la profondeur des rainures 25c,à profondeur moindre,des gorges 25 à profil composite augmentée de la faible épaisseur 24b de colle qui est appliquée sur les espaces 22 séparant les gorges 25 et qui reste après compression de l'empilage 30). Cette épaisseur est choisie en fonction de l'effet esthétique recherché,tout en assurant l'isolation appropriée grâce à la présence des portions de joints 24a remplissant les portions de gorge plus profondes constituées par les évidements 25a.Of course, during the application of the colored glue on each face of the
La figure 9 illustre la configuration d'une des plaques 28 d'un empilage (non représenté) susceptible d'être réalisé pour la mise en oeuvre d'un autre mode de mise en oeuvre du procédé selon l'invention.FIG. 9 illustrates the configuration of one of the
Sur cette plaque 28 a été usinée une pluralité de nervures 32,ayant la même largeur, séparées par deux pluralités de gorges de profondeurs différentes 29 et 31 destinées à être remplies d'une substance colorée différente, de façon à combiner les effets de décoration et d'isolation. Dans ce cas, le découpage serait effectué selon les axes x-x′ et y-y′.On this
La figure 10 illustre une vue en perspective d'un support 33 du type aggloméré ou de type dit MDF et pourvu de rainures et languettes d'emboîtement sur lesquelles sont appliqués plusieurs éléments 14 (bien que ceux-ci pourraient être remplacés par des éléments tels que les éléments 15, 16 et 23 précités) qui assurent un effet décoratif grâce aux joints de colle colorée 3.FIG. 10 illustrates a perspective view of a
Il est facile de vérifier que dans le cas de la figure 1, le découpage en tranches A-B est effectué de manière à supprimer les nervures 5, à savoir les moyens ayant servi à définir l'épaisseur du joint de colle colorée et en assurer l'uniformité sur toute la longueur ; par contre, dans les exemples illustrés aux figures 3 et 5, le découpage des tranches A-B est effectué de manière à inclure totalement ou en partie les moyens conformes à l'invention, à savoir les nervures (ou méplats) 8 et 13, respectivement.It is easy to verify that in the case of FIG. 1, the cutting into slices AB is carried out so as to remove the
Bien entendu, toutes les nervures illustrées aux figures 1, 3, 5, 7 et 9 peuvent être réalisées d'un seul tenant avec les plaques qui les portent (comme illustré aux dessins) ou rapportées; en outre, elles peuvent être continues ou discontinues sur toute leur longueur.Of course, all the ribs illustrated in Figures 1, 3, 5, 7 and 9 can be made in one piece with the plates which carry them (as illustrated in the drawings) or attached; in addition, they can be continuous or discontinuous over their entire length.
En ce qui concerne les plaques de bois utilisées pour réaliser les différents empilages 1, 10, 20, 30, etc... celles-ci peuvent être :
- de même essence ou d'essence différente,
- réalisées d'un seul tenant en bois massif ou constituées par juxtaposition suivant au moins deux directions, notamment perpendiculaires, d'une pluralité de plaquettes de bois massif collées entre elles, comme les plaques 11b de la figure 5 (bien entendu, la colle entre les différentes plaquettes juxtaposées n'est pas colorée comme la colle utilisée entre les plaques superposées),
- disposées avec les fibres parallèles ou perpendiculaires entre elles en passant d'une plaque à la plaque consécutive.Regarding the wooden plates used to make the
- of the same essence or of different essence,
- Made in a single piece of solid wood or formed by juxtaposition in at least two directions, in particular perpendicular, of a plurality of solid wood plates glued together, like the
- arranged with the fibers parallel or perpendicular to each other passing from one plate to the consecutive plate.
En ce qui concerne la colle colorée, celle-ci peut être rigide ou souple, après polymérisation, le caractère de souplesse donnant,au matériau en bois selon l'invention, la flexibilité nécessaire pour s'adapter aux revêtements de surfaces galbées ainsi qu'aux dilatations et aux rétractions du bois, dont il est composé, qui sont dues aux variations hygrométriques et thermiques des lamelles de bois, notamment lorsque celles-ci sont disposées en bois dit "de bout".With regard to the colored adhesive, this can be rigid or flexible, after polymerization, the character of flexibility giving, to the wooden material according to the invention, the flexibility necessary to adapt to coatings of curved surfaces as well as to the expansions and retractions of the wood, of which it is composed, which are due to the hygrometric and thermal variations of the wooden slats, in particular when these are arranged in so-called "end" wood.
Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de mise en oeuvre, de réalisation et d'application qui viennent d'etre décrits de façon plus explicite ; elle en embrasse, au contraire, toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention. En particulier, en ce qui concerne la limite supérieure des joints de colle (notamment lorsqu'on utilise les nervures 5 et 22 comme moyens permettant d'obtenir une épaisseur prédéterminée pour ces joints qui soit aussi uniforme sur toute leur longueur) entre les lamelles adjacentes des éléments obtenus par le procédé selon l'invention, celle-ci est essentiellement imposée par les propriétés de cohésion de la colle utilisée ainsi que par la tenue dans le temps de ces propriétés. En outre, la compression de chaque empilage visant à solidariser par collage les plaques superposées, et donc les lamelles adjacentes du matériau obtenu par découpage de tranches, selon les dispositions qui ont été exposées plus haut, est en tout état de cause inférieure à l'écrasement des fibres du bois utilisé (donc, variable avec la densité des essences de bois) et est effectuée à une température comprise entre la température ambiante et 120°C, et même plus, selon les techniques employées, bien que les valeurs soient fonction du type de colle employé.As is apparent from the above, the invention is in no way limited to those of its modes of implementation, embodiment and application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the scope, or the scope, of the present invention. In particular, as regards the upper limit of the adhesive joints (in particular when the
Bien entendu, les joints de colle colorée peuvent être de la même couleur ou de couleurs différentes, distribuées parmi les différents joints et même dans un même joint, selon les effets esthétiques recherchés,et réalisés à partir d'une colle rigide ou souple ; dans le cas où la colle est souple, elle peut être du type expansé.Of course, the colored glue joints can be of the same color or of different colors, distributed among the different joints and even in the same joint, depending on the desired aesthetic effects, and produced from a rigid or flexible adhesive; in the case where the adhesive is flexible, it may be of the expanded type.
De plus, lorsque les nervures sont rapportées, celles-ci peuvent être réalisées, non seulement en bois, mais également en carton ou à base de matière(s) synthétique(s) ou naturelle(s) non compressibles.In addition, when the ribs are attached, they can be made, not only of wood, but also of cardboard or based on non-compressible synthetic or natural material (s).
En ce qui concerne l'utilisation du matériau obtenu à l'aide du procédé selon l'invention, il y a lieu de signaler la fabrication d'objets de parement, la décoration de surfaces planes ou galbées ainsi que la construction en général.With regard to the use of the material obtained using the method according to the invention, it should be noted the manufacture of facing objects, the decoration of flat or curved surfaces as well as construction in general.
Il y a aussi lieu de signaler que la profondeur des évidements 25a est essentiellement limitée par les propriétés de résistance des lamelles qui en sont équipées.It should also be noted that the depth of the recesses 25a is essentially limited by the resistance properties of the lamellae which are fitted with them.
En outre, l'épaisseur des lamelles de bois peut varier dans une plage de valeurs relativement étendue, par exemple entre 1,5 et 100 mm et même plus selon les besoins et les applications visées.In addition, the thickness of the wooden strips can vary within a relatively wide range of values, for example between 1.5 and 100 mm and even more depending on the needs and the intended applications.
Bien entendu, dans l'exemple de la figure 3, la limite inférieure (non incluse dans la plage de valeurs) pour l'épaisseur du joint 3 de colle colorée est constituée par la faible épaisseur de colle qui est appliquée sur les nervures 5 et qui reste après pressage de l'empilage, de l'ordre de 0,01 mm.Of course, in the example of FIG. 3, the lower limit (not included in the range of values) for the thickness of the
