Abstract

The invention relates to a process for manufacturing a raised panel from a multi-ply panel. This process is characterised in that the outermost ply 2a, 2b of the panel is displaced at the desired location in order to obtain the raising. Moreover, before carrying out this operation, the plys 2a-4a corresponding to the depth of flattening E-e are incised in order to define the flattening zone. The invention also relates to a multi-ply raised panel which is characterised in that the raising (raised feature) is constituted by the outermost ply 2b being pushed in and in that the outermost 2b and innermost 3b, 4b are incised around the raising (raised feature). Application to producing raisings (raised features) on multi-ply panels.

Description

L'invention concerne les panneaux à platesbandes, par exemple les panneaux utilisés pour constituer des portes, des fenêtres ou des boiseries. The invention relates to flatbed panels, for example panels used to form doors, windows or woodwork.

Traditionnellement, les panneaux à platesbandes étaient fabriqués par usinage d'un panneau massif mais cette technique est actuellement réservée à des fabrications de haute gamme d'un coût très élevé. Traditionally, flatbed panels were manufactured by machining a solid panel, but this technique is currently reserved for high-end manufacturing at a very high cost.

On a cherché à mettre au point des techni ques de fabrication moins couteuses fournissant cependant des panneaux ayant un aspect aussi proche que possible de l'aspect traditionnel. Attempts have been made to develop less expensive manufacturing techniques, however, providing panels having an appearance as close as possible to the traditional appearance.

La Demanderesse a ainsi développé une technique de fabrication consistant à utiliser un panneau multiplis comportant un pli interne et un pli externe aussi identiques que possibles, ce panneau étant soumis à un enlèvement de matière pour dégager le pli interne à l'endroit de la plate-bande. Cette technique est décrite par exemple dans la demande de brevet français n0 84 00432 déposée le 12 janvier 1984. The Applicant has thus developed a manufacturing technique consisting in using a plywood panel comprising an internal ply and an external ply as identical as possible, this panel being subjected to removal of material to release the internal ply at the location of the platform. bandaged. This technique is described for example in French patent application No. 84 00432 filed on January 12, 1984.

Cette technique permet effectivement d'abaisser le coût de fabrication mais elle présente l'inconvénient de ne pas réaliser un aspect tout à fait satisfaisant car il n'est pas possible que le pli interne et le pli externe aient exactement le même aspect, notamment en ce qui concerne les veines. D'autre part, le pli interne est un pli onéreux et toute la partie de ce pli qui n'est pas dégagée, c'est-à-dire la majeure partie du pli interne,est inutilement onéreuse puisqu'elle n'est pas exploitée pour son aspect. This technique effectively makes it possible to lower the manufacturing cost but it has the drawback of not achieving a completely satisfactory appearance because it is not possible for the internal fold and the external fold to have exactly the same appearance, in particular in regards to the veins. On the other hand, the internal fold is an expensive fold and the whole part of this fold which is not released, that is to say the major part of the internal fold, is unnecessarily expensive since it is not exploited for its appearance.

La présente invention vise à fournir un nouveau procédé permettant d'éviter ces deux inconvénients.  The present invention aims to provide a new method making it possible to avoid these two drawbacks.

Selon l'invention, on réalise la plate-bande sans usinage, par un écrasement des plis, ce qui a pour conséquence de déplacer le pli externe au niveau de la plate-bande. According to the invention, the bed is produced without machining, by crushing the folds, which has the consequence of displacing the external fold at the level of the bed.

On obtient ainsi un aspect satisfaisant puisque la plate-bande présente exactement le même aspect que la partie qu'elle entoure et on fait l'économie du pli interne. This gives a satisfactory appearance since the flower bed has exactly the same appearance as the part it surrounds and the internal fold is saved.

Dans une réalisation préférée, avant de réaliser cet écrasement, on délimite par une incision des plis externe et internes les zones à écraser, ce qui procure des angles vifs en bordure de la plate-bande. In a preferred embodiment, before carrying out this crushing, the areas to be crushed are delimited by an incision of the external and internal folds, which gives sharp angles at the edge of the flower bed.

Pour mettre en oeuvre le procédé de l'invention, on utilise une presse dont le poinçon présente la forme voulue pour réaliser la plate-bande. To implement the method of the invention, a press is used, the punch of which has the desired shape for producing the flower bed.

Dans le cas des plates-bandes doubles, lloutil- lage de presse permet de former les deux empreintes, soit en une seule opération, soit en deux. In the case of double beds, the press tool makes it possible to form the two impressions, either in a single operation or in two.

Les plis internes du panneau sont réalisés en bois d'essences présentant une bonne compressibilité, le taux d'écrasement étant de l'ordre de 50%. The internal folds of the panel are made of essence wood with good compressibility, the crushing rate being of the order of 50%.

Le pli externe est réalisé en placage dont l'épaisseur se situe entre 3/10 et 221îo mm. The outer ply is made of veneer, the thickness of which is between 3/10 and 221 mm.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre ainsi que sur la figure qui lui est annexée. Other characteristics and advantages of the invention will appear during the description which follows and in the figure which is annexed to it.

Cette figure représente en une vue de coupe, une plate-bande réalisée selon le procédé conforme à la présente invention. This figure shows in a sectional view, a bed produced according to the method according to the present invention.

Comme le montre cette figure, le panneau 1 d'épaisseur E sur lequel on désire réaliser une platebande lb d'épaisseur e, est un panneau du type multiplis. As this figure shows, the panel 1 of thickness E on which it is desired to make a plate 1b of thickness e, is a panel of the plywood type.

Ce panneau comporte un pli externe supérieur 2a, différents plis internes 3a-7a et un pli externe inférieur 8a.This panel comprises an upper external fold 2a, different internal folds 3a-7a and a lower external fold 8a.

Afin de délimiter la zone à écraser qui formera la plate-bande lb, on incise verticalement les plis 2a-4a du panneau d'une épaisseur E-e qui est celle de l'écrasement. L'incision 9 ainsi pratiquée, démarque la zone à écraser et préserve les plis supérieurs 2a,3a et 4a de toute déformation due à l'écrasement. In order to delimit the zone to be crushed which will form the flower bed lb, the folds 2a-4a of the panel are cut vertically with a thickness E-e which is that of the crushing. The incision 9 thus made, demarcates the area to be crushed and preserves the upper folds 2a, 3a and 4a from any deformation due to crushing.

On écrase ensuite le panneau 1 à l'aide d'une presse qui agit selon une force F (représentée par une flèche verticale dirigée vers le bas) jusqu'à réduire l'épaisseur de la zone à écraser de l'épaisseur E du panneau 1 à l'épaisseur désirée e de la plate-bande lb
Cette action a pour conséquence de comprimer les plis 2b-8b du panneau i au niveau de la plate-bande lb. Panel 1 is then crushed using a press which acts according to a force F (represented by a vertical arrow pointing downwards) until the thickness of the area to be crushed is reduced by the thickness E of the panel 1 at the desired thickness e of the flower bed lb
The effect of this action is to compress the folds 2b-8b of the panel i at the level of the bed 1b.

L'incision préalable 9 permet d'obtenir un angle vif 10 en bordure de la plate-bande et limite la déformation des plis aux plis inférieurs 5a-8a. The preliminary incision 9 makes it possible to obtain a sharp angle 10 at the edge of the flower bed and limits the deformation of the folds to the lower folds 5a-8a.

La plate-bande est ainsi réalisée, présenté un pli externe supérieur 2b rigoureusement identique dans son aspect, notamment en ce qui concerne les veines, au pli externe supérieur 2a du reste du panneau la. The flower bed is thus produced, presented with an upper external fold 2b which is strictly identical in appearance, in particular as regards the veins, to the upper external fold 2a of the rest of the panel 1a.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit mais s'étend à toutes les variantes conformes à son esprit.  Of course, the invention is not limited to the embodiment described but extends to all the variants in accordance with its spirit.
