Abstract
Description
Le brevet principal auquel se rattache le présent certificat d'addition a pour objet un procédé de traitement de la surface du bois, notamment du bois sous forme de lames, essentiellement caractérisé par le fait que l'on effectue un cardagesillonage de la surface du bois. The main patent to which this certificate of addition relates relates to a process for treating the surface of wood, in particular wood in the form of blades, essentially characterized by the fact that carding is carried out on the surface of the wood. .
Le procédé selon le brevet principal avait pour but d'éviter les inconvénients du sablage utilisé traditionnellement pour modifier l'aspect traditionnel de la surface du bois, et permettait d'éviter les irrégularités sur la surface du bois, ces irrégularités se traduisant lors du cerusage ultérieur du bois par des épaisseurs de teintures différentes et des différences de tons. The method according to the main patent was intended to avoid the disadvantages of sanding traditionally used to modify the traditional appearance of the surface of the wood, and made it possible to avoid irregularities on the surface of the wood, these irregularities being reflected during cerusage. subsequent wood by different thicknesses of stains and differences in tones.
Dans la pratique les parements des lames en bois à effet décoratif, doivent subir une finition par ponçage. Cette finition est nécessaire pour supprimer les ondulations dues au rabotage. Or le ponçage mécanique, à l'aide de papier de verre, ne peut être appliqué sur les lames comportant une baguette car la bande souple de papier de verre mord alors sur la baguette et la déforme. In practice, the facings of wooden boards with a decorative effect must be finished by sanding. This finish is necessary to remove the ripples due to planing. However, mechanical sanding, using sandpaper, cannot be applied to the blades comprising a rod because the flexible strip of sandpaper then bites onto the rod and deforms it.
En outre on ne peut, dans la pratique, effectuer de ponçage mécanique sur des lames de bois trop résineuses car il se produit un encrassage trés rapide des bandes de ponçage. In addition, it is not possible, in practice, to perform mechanical sanding on overly resinous wooden blades because very rapid fouling of the sanding bands occurs.
La présente invention se propose de fournir un procédé permettant d'effacer dans une trés large mesure les défauts de sciage. Le procédé selon l'invention peut en outre être utilisé pour toutes les qualités de bois, y compris les bois trés résineux, et pour toutes les configurations de lames notamment celles comportant une baguette. The present invention proposes to provide a method for erasing sawing defects to a very large extent. The method according to the invention can also be used for all qualities of wood, including very softwoods, and for all blade configurations, in particular those comprising a strip.
La présente invention a pour objet un procédé de traitement de la surface du bois, notamment du bois sous forme de lames, dans lequel on effectue un traitement mécanique de cardagesillonage de la surface du bois caractérisé par le fait que l'on effectue ce traitement mécanique sur la surface de parement de la lame de bois brute de sciage. The subject of the present invention is a process for treating the surface of wood, in particular wood in the form of blades, in which a mechanical carding process is carried out on the surface of the wood, characterized in that this mechanical treatment is carried out. on the facing surface of the rough sawn wood blade.
Le procédé selon l'invention permet de façon remarquable d'éviter les étapes de rabotage et de ponçage précédemment nécessaires. I1 efface les défauts de sciage et en même temps permet de communiquer à la surface de la lame de bois un aspect esthétique original, caractéristique sous la forme de minuscules sillons longitudinaux dans la lame de bois. The method according to the invention remarkably makes it possible to avoid the planing and sanding steps previously necessary. I1 clears sawing defects and at the same time allows to communicate on the surface of the wooden blade an original aesthetic appearance, characteristic in the form of tiny longitudinal grooves in the wooden blade.
Ces sillons en général de faible profondeur, suivant le fil du bois ou d'orientation quelconque, peuvent être obtenus par toutes techniques conventionnelles, en particulier celles décrites dans le brevet principal, dans lequel le cardage peut par exemple s'effectuer à l'aide d'un ou plusieurs peignes métalliques ou à l'aide d'un ou plusieurs rouleaux munis de pointes. Dans cette dernière technique les rouleaux peuvent être des tambours de bois munis de scies à ruban multiples fixées a leur périphérie, les scies ayant une épaisseur moyenne par exemple de six dixièmes de mm et entant écartées les unes des autres d'environ 2 à 3 mm. De tels dispositifs de cardage sont par exemple utilisés dans l'industrie du traitement de la laine et du coton.On peut également utiliser dans cette technique plusieurs tambours décalés, les écarts entre les sillons formés étant alors réduits au minimum. These grooves, generally of shallow depth, along the grain of the wood or of any orientation, can be obtained by any conventional technique, in particular those described in the main patent, in which carding can for example be carried out using one or more metal combs or using one or more rollers fitted with spikes. In the latter technique the rollers can be wooden drums fitted with multiple band saws fixed at their periphery, the saws having an average thickness for example of six tenths of a mm and being spaced apart from each other by approximately 2 to 3 mm . Such carding devices are used, for example, in the wool and cotton processing industry. Several offset drums can also be used in this technique, the gaps between the grooves formed being reduced to a minimum.
I1 est également possible de communiquer à la surface du bois, en plus des sillons, par exemple des pointillés ou toute autre configuration géométrique, selon l'aspect particulier que l'on cherche à obtenir. It is also possible to communicate on the surface of the wood, in addition to the grooves, for example dotted lines or any other geometrical configuration, depending on the particular aspect that one seeks to obtain.
On constate de façon remarquable que l'invention permet de conférer au parement du bois brut de sciage un aspect original avantageux intermédiaire entre le raboté et le brut de sciage et ce, de manière particulièrement simple et économique. It is remarkably noted that the invention makes it possible to give the rough sawn wood facing an advantageous original appearance intermediate between the planed and the rough sawn, in a particularly simple and economical manner.
De plus, l'absence de l'opération de rabotage permet de réaliser des lames ayant une épaisseur de 12mm en évitant les pertes d'épaisseur dues au rabotage et qui ramènent l'épaisseur des lames rabotées à lame, ce qui offre de meilleures qualités d'isolation thermique et phonique. Si, par ailleurs, on cherche à réaliser des lames brutes de sciage de 10 min d'épaisseur, on peut réaliser deux lames dans un débit classique de 22mm d'où un gain de 18 % par rapport à l'utilisation d'un débit de 27mm nécessaire à l'obtention de deux lames conventionnelles rabotées de lOmm d'épaisseur. In addition, the absence of the planing operation makes it possible to produce blades having a thickness of 12 mm while avoiding the losses of thickness due to planing and which reduce the thickness of the planed blades to blade, which offers better qualities. thermal and sound insulation. If, moreover, it is sought to produce rough saw blades 10 min thick, two blades can be produced in a conventional flow of 22mm, resulting in a gain of 18% compared to the use of a flow of 27mm necessary to obtain two conventional planed blades 10mm thick.
Bien que l'invention ait été décrite en liaison avec une forme de réalisation particulière il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter diverses modifications sans pour cela sortir ni de son cadre ni de son esprit. Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be made various modifications without departing from its scope or its spirit. .
