Description

La présente invention concerne un procédé de fabrication de lames rainurées ou moulurées telles que lames de volets, moulures de menuiserie ou de bâtiment et le dispositif pour la mise en oeuvre du procédé.The present invention relates to a method of manufacturing grooved or molded blades such as shutter blades, carpentry or building moldings and the device for implementing the method.

La fabrication de lames rainurées ou moulurées est réalisée de manière connue à partir d'un bastaing que l'on débite lame par lame ou simultanément, chaque lame étant ensuite l'une après l'autre usinée sur une machine de rainurage ou de moulurage.The manufacture of grooved or molded blades is carried out in a known manner from a bastaing which is cut blade by blade or simultaneously, each blade then being machined one after the other on a grooving or molding machine.

Dans le cas de fabrication de lames de volets battants, celles-ci comportent sur leurs petits côtés longitudinaux une rainure et une languette obtenue par l'usinage précédent.In the case of the manufacture of hinged shutter blades, these have on their short longitudinal sides a groove and a tongue obtained by the previous machining.

L'assemblage des lames est du type rainure et languette. Il est connu afin de consolider les volets battants formés par cet assemblage de brocher entre elles les lames.The assembly of the blades is of the groove and tongue type. It is known to consolidate the shutters formed by this assembly of broaching the blades together.

A cet effet, après un usinage des lames, celles-ci sont rassemblées et percées et/ou entaillées perpendiculairement du petit côté usiné.To this end, after machining the blades, they are assembled and drilled and / or cut perpendicularly from the small machined side.

Les broches de consolidation passent donc dans les perçages ou entailles réalisés dans les lames et assurent donc leur serrage.The consolidation pins therefore pass through the holes or notches made in the blades and therefore ensure their tightening.

Il s'est avéré que ce procédé présente de nombreux inconvénients grévant la production et donc le coût des lames rainurées ou moulurées.It turned out that this process has many drawbacks affecting production and therefore the cost of grooved or molded blades.

En effet, les usinages se faisant indépendamment les uns des autres, ceci entraîne des reprises des pièces usinées nécessitant de nouveaux réglages sur les machines assurant les usinages suivants.In fact, the machining operations being carried out independently of each other, this results in resumptions of the machined parts requiring new adjustments on the machines ensuring the following machining operations.

Ces reprises et ces réglages amènent des pertes de temps et une baisse considérable du rendement de la fabrication.These rework and adjustments lead to loss of time and a considerable drop in production efficiency.

Cependant, il est connu dans le brevet européen EP-A-53835 de réaliser sur un bastaing une mise à longueur après le corroyage et d'effectuer des usinages de forme et des délignages ou sciages sans reprise.However, it is known in European patent EP-A-53835 to carry out a cutting to length after the bending and to carry out shape machining and edging or sawing without resumption.

Ce dispositif présente toutefois un inconvénient pour les réglages entre la position des outils de sciage et la position des outils de forme qui sont portés respectivement par des arbres différents sur une même machine.However, this device has a drawback for the adjustments between the position of the sawing tools and the position of the shaped tools which are carried respectively by different shafts on the same machine.

De plus, on connaît par le brevet DE-C-49372 un dispositif doté d'un arbre supérieur portant des outils de forme et d'un arbre inférieur portant des outils de forme et/ou des outils de sciage et qui est destiné à la fabrication de linteaux moulurés.In addition, patent DE-C-49372 discloses a device provided with an upper shaft carrying form tools and a lower shaft carrying form tools and / or sawing tools and which is intended for manufacture of molded lintels.

Les outils de forme de l'arbre supérieur sont pour certains dotés de parties saillantes réalisant une forme définissant une amorce de séparation.The tools for shaping the upper shaft are, for some, provided with protruding parts forming a shape defining a separation primer.

Cependant, la réalisation de cette amorce de séparation est limitée par l'épaisseur des planches à usiner et d'autre part, l'emploi de ce type d'outil ne permet pas une grande étendue de possibilités sur les formes puisque celles-ci sont liées à la présence d'amorce de séparation et à l'épaisseur des planches à usiner.However, the realization of this separation primer is limited by the thickness of the boards to be machined and on the other hand, the use of this type of tool does not allow a large range of possibilities on the forms since these are linked to the presence of separation primer and the thickness of the boards to be machined.

Sur l'arbre inférieur du dispositif de ce brevet DE-C-49372 sont montés des outils de forme et/ou des outils de sciage.Shaped tools and / or sawing tools are mounted on the lower shaft of the device of this patent DE-C-49372.

Les outils de forme de l'arbre inférieur présentent un profil qui doit permettre la séparation de la planche en linteaux en réalisant une forme au droit de l'amorce de séparation précédemment obtenue par les outils de forme de l'arbre supérieur.The tools for shaping the lower shaft have a profile which must allow the separation of the board into lintels by making a shape in line with the separation primer previously obtained by the tools for shaping the upper shaft.

Ce double rôle des outils de forme limite à nouveau l'étendue des possibilités des formes et de plus dans le cas où les pièces à usiner sont très épaisses il n'est plus possible d'obtenir la forme et la séparation en même temps, ce qui constitue à nouveau une limitation dans le domaine d'utilisation.This double role of the form tools again limits the extent of the possibilities of the forms and moreover in the case where the workpieces are very thick it is no longer possible to obtain the form and the separation at the same time, this which again constitutes a limitation in the field of use.

La présente invention vise à obvier à l'ensemble de ces inconvénients en proposant un procédé de fabrication éliminant les reprises du produit pour l'usinage suivant et donc les réglages, en assurant de façon sûre le positionnement des surfaces usinées de la pièce les unes aux autres et en offrant un large étendue de possibilités dans les formes et les dimensions des pièces à usiner et en présentant un dispositif pour la mise en oeuvre de ce procédé.The present invention aims to obviate all of these drawbacks by proposing a manufacturing process eliminating the rework of the product for the following machining and therefore the adjustments, by ensuring in a secure manner the positioning of the machined surfaces of the part one against the other. others and by offering a wide range of possibilities in the shapes and dimensions of the workpieces and by presenting a device for the implementation of this process.

A cet effet, le procédé de fabrication de lames rainurées ou moulurées, de moulures de menuiserie ou de bâtiments selon l'invention à partir d'un bastaing corroyé et mis à longueur comporte un usinage avec un arbre rotatif inférieur et un arbre rotatif supérieur qui se trouvent transversalement par rapport à ce bastaing guidé et déplacé sur une place horizontale, les arbres portant des outils de coupe profilés dont les arêtes sont alignées les unes avec les autres pour que le bastaing soit profilé et simultanément partagé en plusieurs lames profilées et se caractérise en ce que les outils sont composés en série alternée par des fraises individuelles à arête profilée et des lames de scies circulaires.To this end, the method of manufacturing grooved or molded blades, carpentry moldings or buildings according to the invention from a bastaing wrought and cut to length comprises machining with a lower rotary shaft and an upper rotary shaft which lie transversely to this bastaing guided and moved on a horizontal place, the shafts carrying profiled cutting tools whose edges are aligned with each other so that the bastaing is profiled and simultaneously divided into several profiled blades and is characterized in that the tools are composed in alternating series by individual milling cutters with profiled edge and circular saw blades.

Le procédé de fabrication de lames rainurées ou moulurées, de moulures de menuiserie ou de bâtiment ou autres selon l'invention consiste à partir d'un bastaing corroyé à usiner des formes sur la face inférieure du bastaing 3 et à réaliser simultanément des sciages sur la moitié de la hauteur inférieure dudit bastaing entre deux usinages de forme et/ou entre un usinage de forme et un bord du bastaing 3 et à usiner des formes sur la face supérieure dudit bastaing et à réaliser simultanément des sciages sur la moitié de la hauteur supérieure du bastaing 3 entre deux usinages de forme et/ou entre un usinage de forme et un bord dudit bastaing et dans les mêmes plans que les sciages réalisés sur la moitié de la hauteur inférieure.The method of manufacturing grooved or molded blades, carpentry or building moldings or the like according to the invention consists of using a bastaing wrought to machine shapes on the underside of the bastaing 3 and to simultaneously sawn on the half of the lower height of said bastaing between two usi form swings and / or between a form machining and an edge of the bastaing 3 and to machine forms on the upper face of said bastaing and to simultaneously sawn on half of the upper height of the bastaing 3 between two form machining and / or between a form machining and an edge of said bastaing and in the same planes as sawn timber produced on half of the lower height.

Le procédé de fabrication est mis en oeuvre par usinage avec un arbre rotatif inférieur et un arbre rotatif supérieur qui se trouvent transversalement par rapport à ce bastaing guidé et déplacé sur une table horizontale, les arbres portant des outils de coupe profilés dont les arêtes sont alignées les unes aux autres pour que le bastaing soit profilé et simultanément partagé en plusieurs lames profilées.The manufacturing process is implemented by machining with a lower rotary shaft and an upper rotary shaft which lie transversely relative to this guided bastaing and moved on a horizontal table, the shafts carrying profiled cutting tools whose edges are aligned to each other so that the bastaing is profiled and simultaneously divided into several profiled blades.

Les outils sont composés en série alternée par des fraises individuelles à arêtes profilées et des lames de scies circulaires individuelles.The tools are composed in alternating series by individual cutters with profiled edges and individual circular saw blades.

Préférentiellement, dans le procédé selon l'invention avant le sciage et l'usinage de forme simultanés dans au moins un même plan et après le corroyage du bastaing est réalisé une mise à longueur dudit bastaing.Preferably, in the process according to the invention before simultaneous sawing and machining in shape in at least the same plane and after the bending of the bastaing, the bastaing is cut to length.

Les lames rainurées ou moulurées ou moulures obtenues par le procédé selon l'invention peuvent être utilisées dans des applications différentes.The grooved or molded blades or moldings obtained by the process according to the invention can be used in different applications.

Dans le cas où ces lames sont destinées à la construction par exemple d'un volet battant, l'assemblage de celles-ci est réalisé par l'intermédiaire de broches d'acier.In the case where these blades are intended for the construction for example of a beating shutter, the assembly of these is carried out by means of steel pins.

En conséquence, les lames en sortie de fabrication doivent comporter des orifices transversaux de passage de broches.Consequently, the blades at the end of manufacture must have transverse holes for the passage of pins.

A cet effet, le procédé selon l'invention de fabrication de lames rainurées ou moulurées de moulures de bâtiment ou de menuiserie et plus particulièrement de lames dont l'assemblage est réalisé par l'intermédiaire de broches pour former un volet battant ou autres, consiste à réaliser, après la mise à longueur du bastaing corroyé et avant les usinages de forme et les sciages simultanés, des perçages disposés suivant des lignes et des colonnes, ménagés perpendiculairement dans une grande face dudit bastaing et le traversant de part en part.To this end, the method according to the invention for manufacturing grooved or molded blades of building or carpentry moldings and more particularly of blades, the assembly of which is carried out by means of pins to form a swinging shutter or the like, consists to carry out, after the lengthening of the bastaing wrought and before the machining of form and the simultaneous sawing, of the bores arranged according to lines and columns, formed perpendicularly in a large face of said bastaing and crossing it right through.

Les lames rainurées ou moulurées destinées par exemple à la construction de volets battants, de planchers ou autres comportent sur leurs tranches un profil d'assemblage, par exemple une languette 30 et une rainure 31 respectivement sur chaque tranche (figure 5) et peuvent être obtenue par le procédé ci-dessus énoncé.The grooved or molded blades intended for example for the construction of swing shutters, floors or the like comprise on their edges an assembly profile, for example a tongue 30 and a groove 31 respectively on each edge (FIG. 5) and can be obtained by the method stated above.

Le procédé selon l'invention permet d'obtenir simultanément toutes les lames rainurées ou moulurées par usinage de forme et sciage simultanés.The method according to the invention makes it possible to simultaneously obtain all the grooved or molded blades by simultaneous shape machining and sawing.

Le dispositif pour la mise en oeuvre du procédé selon l'invention représenté en figure 1 comprend un poste de corroyage 1, un poste de mise à longueur 2 des bastaings 3 précédemment corroyés, des moyens de transfert 4 du poste de corroyage 1 au poste de mise à longueur 2, un ensemble de sciage et d'usinage 5 simultanés et des moyens d'amenage 6 des bastaings 3 entre le poste de mise à longueur 2 et l'ensemble de sciage et d'usinage simultanés 5.The device for implementing the method according to the invention shown in FIG. 1 comprises a working station 1, a working station 2 for the lengths of the bastaings 3 previously worked, transfer means 4 from the working station 1 to the work station cut-to-length 2, a simultaneous sawing and machining assembly 5 and means for feeding 6 the bastaings 3 between the length-cutting station 2 and the simultaneous sawing and machining assembly 5.

Dans le cas où le dispositif de mise en oeuvre du procédé selon l'invention est destiné à la fabrication de lames rainurées ou moulurées dont l'assemblage est effectué par l'intermédiaire de broches d'acier pour, par exemple, former des volets battants ou autres, ledit dispositif comporte entre le poste de mise à longueur 2 d'un bastaing 3 et l'ensemble de sciage et d'usinage simultanés 5, un poste de perçage 7.In the case where the device for implementing the method according to the invention is intended for the manufacture of grooved or molded blades, the assembly of which is carried out by means of steel pins in order, for example, to form shutters or others, said device comprises, between the lengthening station 2 of a bastaing 3 and the simultaneous sawing and machining assembly 5, a drilling station 7.

Avant ou après ce poste de perçage, le dispositif peut comporter des postes de mortaisage et/ou d'entaillage ou selon une autre forme de réalisation dépendant de l'utilisation des lames ou moulures le dispositif est doté entre le poste de mise à longueur et l'ensemble de mortaisage et/ou d'entaillage.Before or after this drilling station, the device can include slotting and / or notching stations or according to another embodiment depending on the use of the blades or moldings the device is provided between the cutting station and the set of slotting and / or notching.

Le poste de corroyage 1 du dispositif selon l'invention de type connu permet l'usinage des côtés et des grandes faces de bastaing 3 par fraisage et/ou rabotage pour leur mise à dimensions.The working station 1 of the device according to the invention of known type allows the machining of the sides and large faces of bastaing 3 by milling and / or planing for their dimensioning.

Les bastaings 3 sont disposés sur une table 8, de préférence mobile, du poste de corroyage et sont usinés en continu dans ledit poste.The bastaings 3 are arranged on a table 8, preferably mobile, of the wrought-out station and are machined continuously in said station.

A la sortie du poste de corroyage 1, les bastaings sont amenés vers le poste de mise à longueur 2 par les moyens de transfert 4.At the exit from the wrinkling station 1, the bastaings are brought to the lengthening station 2 by the transfer means 4.

Ces moyens de transfert sont de préférence constitués par un tapis sans fin 9 amenant le bastaing 3 contre une butée 10 et par une palette 11 actionnée en translation perpendiculairement au tapis 9 par au moins un vérin 12.These transfer means are preferably constituted by an endless belt 9 bringing the bastaing 3 against a stop 10 and by a pallet 11 actuated in translation perpendicular to the belt 9 by at least one jack 12.

Le bastaing 3 repose lors de son transfert sur deux barres 14 et est guidé par des plaques latérales 15 jusqu'au poste de mise à longueur 2.The bastaing 3 rests during its transfer on two bars 14 and is guided by side plates 15 to the lengthening station 2.

Ce poste de mise à longueur 2 comprend suivant une forme préférentielle de réalisation deux scies circulaires 13 ou autres espacées l'une de l'autre d'une valeur réglable égale à la longueur désirée du bastaing.This lengthening station 2 comprises according to a preferred embodiment two circular saws 13 or other spaced from each other by an adjustable value equal to the desired length of the bastaing.

Ledit bastaing est poussé entre ces deux scies par la palette 1 puis jusqu'aux moyens d'amenage 6 des bastaings vers l'ensemble d'usinage et de sciage simultanés 5.Said bastaing is pushed between these two saws by the pallet 1 and then to the means of feeding 6 of the bastaings towards the simultaneous machining and sawing assembly 5.

Les moyens d'amenage 6 sont de préférence également constitués par un tapis sans fin 16 ; mais il va de soi que tout autre type de moyens peut convenir.The feeding means 6 are preferably also constituted by an endless belt 16; but it goes without saying that any other type of means may be suitable.

Dans le cas où le dispositif est apte à produire des lames destinées à être assemblées par l'intermédiaire de broches d'acier, les moyens d'amenage 6 comportent au moins un moyen de manutention 17 des bastaings vers le poste de perçage 7.In the case where the device is capable of producing blades intended to be assembled by means of steel pins, the supply means 6 comprise at least one means of handling 17 of the bastaings towards the drilling station 7.

Ce moyen de manutention 17 est constitué selon une forme préférentielle de réalisation par un poussoir 17A agissant perpendiculairement au tapis sans fin 16.This handling means 17 is constituted according to a preferred embodiment by a pusher 17A acting perpendicular to the endless belt 16.

A l'extrémité du tapis sans fin 16 est montée une butée 18. Lorsque le bastaing vient en contact avec cette butée, le poussoir 17A amène ledit bastaing vers le poste de perçage 7. Avantageusement, le dispositif selon l'invention est doté de deux poussoirs 17A agissant parallèlement et permettant le chargement de deux bastaings 3 sur le poste de perçage. Il va de soi que le dispositif selon l'invention comporte des guides entre le tapis sans fin 16 et le poste de perçage 7. Les bastaings sont mis en position et maintenus sous ledit poste de perçage 7 par les poussoirs 17A. Le poste de perçage 7 est constitué de préférence par au moins une perceuse verticale multi-broches permettant le perçage de tous les trous simultanément.At the end of the endless belt 16 is mounted a stop 18. When the bastaing comes into contact with this stop, the pusher 17A brings said bastaing towards the drilling station 7. Advantageously, the device according to the invention is provided with two pushers 17A acting in parallel and allowing the loading of two bastaings 3 on the drilling station. It goes without saying that the device according to the invention comprises guides between the endless belt 16 and the drilling station 7. The bastaings are brought into position and maintained under said drilling station 7 by the pushers 17A. The drilling station 7 preferably consists of at least one vertical multi-spindle drill allowing the drilling of all the holes simultaneously.

Les perçages sont alignés suivant des lignes et des colonnes. Le nombre de colonnes est fonction de la longueur des bastaings et de leur destination quant à leur utilisation. Le nombre de lignes est égal au nombre de lames rainurées ou moulurées délignées en sortie du dispositif selon l'invention. Avantageusement, les broches de la perçeuse peuvent être espacées l'une de l'autre de manière réglable et en fonction des paramètres précédemment énoncés.The holes are aligned in rows and columns. The number of columns depends on the length of the bastaings and their destination for their use. The number of lines is equal to the number of grooved or molded strips delineated at the outlet of the device according to the invention. Advantageously, the pins of the drill can be spaced apart from each other in an adjustable manner and according to the parameters set out above.

Les perçages sont réalisés sur une grande face horizontale du bastaing 3 et traversent celui-ci de part en part. Selon une autre forme de réalisation le poste de perçage peut comporter au moins une perceuse horizontale afin de réaliser des perçages sur les faces verticales du bastaing. Avantageusement le dispositif peut être doté d'au moins un poste de perçage et/ou de mortaisage et/ou d'entaillage. Après la réalisation des perçages et/ou entailles et/ou mortaises suivant la disposition sus-énoncée, les bastaings sont amenés vers l'ensemble d'usinage et de sciage simultanés 5 par le poussoir 17A.The holes are made on a large horizontal face of the bastaing 3 and pass through it right through. According to another embodiment, the drilling station may include at least one horizontal drill in order to make holes on the vertical faces of the bastaing. Advantageously, the device can be provided with at least one drilling and / or slotting and / or notching station. After drilling and / or notches and / or mortises according to the above-mentioned arrangement, the bastaings are brought to the simultaneous machining and sawing assembly 5 by the pusher 17A.

Préférentiellement, les bastaings 3 sont déposés sur un tapis sans fin 5A qui les amène vers ledit ensemble 5. L'ensemble d'usinage de forme et de sciage simultanés 5 du dispositif selon l'invention représenté en figure 2 comporte un bâti 19, une table mobile 20 à rouleaux 21 entrai- nés en rotation, une série de rouleaux supérieurs 22 alignés sur un plan parallèle à la table mobile 20 dont au moins un est entraîné et réglable en hauteur, un arbre inférieur 23 et un arbre supérieur 24 rotatifs. Les arbres supérieur 24 et inférieur 23 sont parallèles et préférentiellement décalés l'un par rapport à l'autre.Preferably, the bastaings 3 are deposited on an endless belt 5A which brings them towards said assembly 5. The assembly of simultaneous shape and sawing 5 of the device according to the invention shown in FIG. 2 comprises a frame 19, a movable table 20 with rollers 21 driven in rotation, a series of upper rollers 22 aligned on a plane parallel to the movable table 20 at least one of which is driven and adjustable in height, a lower shaft 23 and an upper shaft 24 rotatable. The upper 24 and lower 23 shafts are parallel and preferably offset from one another.

Selon une forme préférentielle de réalisation, l'arbre inférieur 23 est décalé vers l'arrière par rapport à l'arbre supérieur 24 suivant le sens d'avancement des bastaings dans l'ensemble 5. Sur chacun des arbres supérieur 24 et inférieur 23 sont montés des outils de sciage 25 et des outils d'usinage de forme 26.According to a preferred embodiment, the lower shaft 23 is offset rearward relative to the upper shaft 24 according to the direction of advance of the bastaings in the assembly 5. On each of the upper 24 and lower 23 shafts are mounted sawing tools 25 and shaped machining tools 26.

Comme représenté aux figures 3 et 4, les outils d'usinage de forme 26 de chaque arbre 23 et 24 constituent des entretoises entre les outils de sciage 25. Les outils de sciage 25 sont constitués par des scies circulaires et sont disposés sur les arbres 23 et 24 suivant plusieurs plans parallèles perpendiculaires auxdits arbres.As shown in Figures 3 and 4, the shape machining tools 26 of each shaft 23 and 24 constitute spacers between the sawing tools 25. The sawing tools 25 are constituted by circular saws and are arranged on the shafts 23 and 24 along several parallel planes perpendicular to said trees.

Les outils de forme 26 sont constitués par exemple par des fraises présentant un profil correspondant à une moulure ou rainure, ou autres que l'on désire obtenir sur les lames.The shaped tools 26 are constituted for example by milling cutters having a profile corresponding to a molding or groove, or the like which it is desired to obtain on the blades.

Les outils de sciage 25 et les outils d'usinage de forme 26 de l'arbre inférieur 23 sont alignés suivant plusieurs plans parallèles perpendiculaires audit arbre aux outils de sciage 25 et aux outils d'usinage de forme 26 de l'arbre supérieur 24.The sawing tools 25 and the shape machining tools 26 of the lower shaft 23 are aligned along several parallel planes perpendicular to said shaft to the sawing tools 25 and to the shape machining tools 26 of the upper shaft 24.

Les outils de forme représentés aux figures 3 et 4 sont adaptés à réaliser une rainure 31 (figure 3) et une languette 30 (figure 4) mais il va de soi que tout autre outil peut être utilisé pour réaliser d'autres profils.The shaped tools shown in Figures 3 and 4 are suitable for making a groove 31 (Figure 3) and a tongue 30 (Figure 4) but it goes without saying that any other tool can be used to make other profiles.

Par exemple, les outils de forme peuvent présenter un profil apte à réaliser des moulures de menuiserie telles que représentées en figure 7.For example, the forming tools can have a profile capable of producing joinery moldings as shown in FIG. 7.

Dans l'ensemble de sciage et d'usinage de forme simultanés 5, le bastaing 3 est entraîné par les rouleaux 21 de la table 20 puis par au moins un rouleau 22 supérieur entre les outils de sciage 25 et d'usinage 26.In the simultaneous sawing and machining assembly 5, the bastaing 3 is driven by the rollers 21 of the table 20 and then by at least one upper roller 22 between the sawing 25 and machining tools 26.

Avantageusement, l'ensemble 5 comporte des moyens de mise en position des bastaings 3 par rapport aux outils et en fonction de la position des lignes de perçages.Advantageously, the assembly 5 includes means for positioning the bastaings 3 relative to the tools and according to the position of the drilling lines.

Ainsi les bastaings sont positionnés dans l'ensemble 5 de manière à ce qu'une ligne de perçages passe entre deux outils de sciage 25.Thus the bastaings are positioned in the assembly 5 so that a line of holes passes between two sawing tools 25.

Les bastaings 3 sont tout d'abord usinés sur leur face inférieure par les outils d'usinage 26 de l'arbre inférieur 23 et sont sciés sur la moitié de leur hauteur inférieure par les scies circulaires 25 de l'arbre inférieur simultanément à l'usinage et dans un même plan perpendiculaire à la face inférieure.The bastaings 3 are first of all machined on their lower face by the machining tools 26 of the lower shaft 23 and are sawn over half of their lower height by circular saws 25 of the lower shaft simultaneously with the machining and in the same plane perpendicular to the underside.

Lorsque les bastaings arrivent à la hauteur de l'arbre supérieur 24, la face supérieure est usinée et le sciage est achevé simultanément et dans le même plan perpendiculaire à la face supérieure par les scies circulaires travaillant la moitié supérieure de la hauteur dudit bastaing.When the bastaings arrive at the height of the upper shaft 24, the upper face is machined and sawing is completed simultaneously and in the same plane perpendicular to the upper face by circular saws working the upper half of the height of said bastaing.

Préférentiellement, le dispositif selon l'invention comporte immédiatement après le dernier arbre portant les outils de sciage et d'usinage de forme au moins une paire de série de rouleaux de forme 32 parallèles, inférieure et supérieure entraînées en rotation afin d'assurer la translation et le maintien de chacune des lames L dans le sens de la hauteur.Preferably, the device according to the invention comprises immediately after the last shaft carrying the sawing and machining tools of form at least one pair of series of rollers of shape 32 parallel, lower and upper driven in rotation in order to ensure translation and maintaining each of the blades L in the height direction.

Ces séries de rouleaux de forme 32 sont fixées chacune sur un arbre supérieur et sur un arbre inférieur entraînés en rotation et parallèles l'un à l'autre.These series of form rollers 32 are each fixed on an upper shaft and on a lower shaft driven in rotation and parallel to each other.

Les rouleaux de chaque série sont alignés avec les outils d'usinage de forme et présentent le même profil que le profil obtenu par l'outil de forme avec lesquels ils sont alignés. Avantageusement, le dispositif selon l'invention est doté de deux paires de séries de rouleaux de forme 32 inférieures et supérieures.The rollers of each series are aligned with the shape machining tools and have the same profile as the profile obtained by the shape tool with which they are aligned. Advantageously, the device according to the invention is provided with two pairs of series of lower and upper form rollers 32.

Ces rouleaux de forme 32 permettent en les maintenant chacune d'éviter aux lames L de se déplacer les unes par rapport aux autres et évitent le vrillage desdites lames afin d'éliminer les risques de coincement des outils de sciage.These shaped rollers 32 make it possible, by holding each of them, to prevent the blades L from moving relative to one another and avoid the twisting of said blades in order to eliminate the risks of jamming of the sawing tools.

Ainsi comme représenté en figure 5, lorsque le bastaing sort du dispositif selon l'invention, toutes les lames L sont débitées et usinées simultanément.Thus, as shown in FIG. 5, when the bastaing leaves the device according to the invention, all the blades L are cut and machined simultaneously.

L'ensemble de sciage et d'usinage comporte avantageusement des moyens d'aspiration de préférence sur chaque outil, des moyens d'entraînement des arbres inférieur et supérieur ainsi que des moyens d'entraînement des rouleaux, des éléments de réglage de leur position en hauteur par rapport à la table mobile 20.The sawing and machining assembly advantageously comprises suction means preferably on each tool, means for driving the lower and upper shafts as well as means for driving the rollers, elements for adjusting their position in height from movable table 20.

Avantageusement, les arbres inférieur 23 et supérieur 24 peuvent être disposés l'un par rapport à l'autre et dans le plan horizontal de manière variable afin que l'ensemble 5 accepte toutes les hauteurs de bastaings.Advantageously, the lower 23 and upper 24 shafts can be arranged with respect to each other and in the horizontal plane in a variable manner so that the assembly 5 accepts all the heights of bastaings.

Selon une forme préférentielle de réalisation les arbres 23 et 24 sont guidés dans des doubles paliers (non représentés).According to a preferred embodiment, the shafts 23 and 24 are guided in double bearings (not shown).

Le dispositif pour la mise en oeuvre du procédé selon l'invention est avantageusement automatique, afin de pouvoir travailler en continu.The device for implementing the method according to the invention is advantageously automatic, in order to be able to work continuously.

Il va donc de soi que ledit dispositif comporte sur les différentes butées des moyens de transfert et sur ces différents postes de travail des contacts émettant des informations aux organes moteurs.It therefore goes without saying that said device comprises on the different stops transfer means and on these different workstations contacts transmitting information to the drive members.

Le procédé et le dispositif pour sa mise en oeuvre selon l'invention permet de produire de manière continue et rapide des lames rainurées ou moulurées sans qu'il soit nécessaire d'effectuer des réglages sur les différents postes de travail après chaque opération.The method and the device for its implementation according to the invention makes it possible to continuously and quickly produce grooved or molded blades without the need to make adjustments on the various workstations after each operation.
