Description

La présente invention concerne un dispositif et un procédé d'encollage d'éléments allongés profilés comportant une surface plane suivant l'axe longitudinal dudit élément.The present invention relates to a device and a method for gluing elongated profiled elements comprising a flat surface along the longitudinal axis of said element.

L'invention est particulièrement bien adaptée à l'encollage de moule-gorges servant à la fabrication de barres cintrées profilées en matériaux composites constituant les arbres creux flexibles.The invention is particularly well suited to the gluing of mold-grooves used for the manufacture of curved bars profiled in composite materials constituting the flexible hollow shafts.

Un procédé et un appareillage pour fabriquer ces barres à section profilée en matière réticulable armée sont décrits par exemple dans le brevet français FR-2.312.356. Dans ce procédé, qui utilise un moule-gorge de section correspondante à celle du profilé à obtenir, on enroule des éléments de renforcement imprégnés de résine réticulable sur un mandrin dans un moule-gorge. On procède ensuite à une réticulation de la matière réticulable avant de séparer du mandrin la barre cintrée profilée et armée. Dans certaines applications de ce procédé, le moule-gorge n'est pas séparé de la barre obtenue et il est même souhaitable qu'ils soient tous deux bien liés.A method and an apparatus for manufacturing these bars with a profiled section of reinforced crosslinkable material are described for example in French patent FR-2,312,356. In this method, which uses a groove section corresponding to that of the profile to be obtained, reinforcing elements impregnated with crosslinkable resin are wound on a mandrel in a groove mold. A crosslinking of the crosslinkable material is then carried out before the profiled and reinforced curved bar is separated from the mandrel. In certain applications of this method, the groove mold is not separated from the bar obtained and it is even desirable that they are both well bonded.

Le document GB-1.359.549 décrit un dispositif permettant d'appliquer un liquide visqueux sur la surface d'un élément à l'aide d'une roue, la quantité de liquide à déposer étant contrôlée par une chambre annulaire. Ce dispositif ne permet cependant pas d'encoller les parois internes d'un élément.Document GB-1,359,549 describes a device making it possible to apply a viscous liquid to the surface of an element using a wheel, the quantity of liquid to be deposited being controlled by an annular chamber. However, this device does not allow the internal walls of an element to be glued.

L'objet de la présente invention est par suite de fournir un procédé et un dispositif pour encoller les parois internes du moule-gorge, notamment les parois latérales.The object of the present invention is therefore to provide a method and a device for gluing the internal walls of the groove mold, in particular the side walls.

L'invention fournit un dispositif d'encollage d'un élément allongé profilé ayant un axe longitudinal, cet élément comportant au moins une surface latérale.The invention provides a device for gluing an elongated profiled element having a longitudinal axis, this element comprising at least one lateral surface.

Ce dispositif selon l'invention comporte une roue ayant un axe, ladite surface latérale étant sensiblement parallèle audit axe longitudinal au moins localement au voisinage de la roue, la roue étant animée d'un mouvement de rotation et comportant au moins une surface annulaire centrée sur l'axe de la roue, est caractérisé en ce que la surface annulaire a un pourtour extérieur et est adaptée à coopérer avec la surface latérale dudit élément au cours d'un déplacement de la roue relativement audit élément suivant un axe parallèle à l'axe longitudinal de l'élément, et en ce qu'il comporte des moyens d'enduction adaptés à déposer au moins sur le pourtour extérieur de la surface annulaire une quantité suffisante d'une colle permettant l'encollage de la surface latérale de l'élément allongé.This device according to the invention comprises a wheel having an axis, said lateral surface being substantially parallel to said longitudinal axis at least locally in the vicinity of the wheel, the wheel being driven in a rotational movement and comprising at least one annular surface centered on the axis of the wheel, is characterized in that the annular surface has an outer periphery and is adapted to cooperate with the lateral surface of said element during a movement of the wheel relative to said element along an axis parallel to the axis longitudinal of the element, and in that it comprises coating means adapted to deposit at least on the outer periphery of the annular surface a sufficient quantity of an adhesive allowing the gluing of the lateral surface of the element elongate.

Lorsque l'élément allongé comporte en outre une surface du fond de gorge différente d'une surface latérale et profilée selon l'axe dudit élément telle la surface du fond d'une gorge ou encore une surface sensiblement perpendiculaire à la surface latérale, la roue pourra comporter une surface osculatrice circonférentielle adaptée à coopérer avec la surface du fond de gorge. Les moyens d'enduction pourront être adaptés à déposer sur la surface osculatrice une quantité suffisante de colle permettant l'encollage de la surface du fond de gorge.When the elongated element also comprises a surface of the groove bottom different from a lateral surface and profiled along the axis of said element such as the surface of the bottom of a groove or else a surface substantially perpendicular to the lateral surface, the wheel may include a circumferential osculating surface adapted to cooperate with the surface of the throat bottom. The coating means may be adapted to deposit on the osculating surface a sufficient quantity of glue allowing the gluing of the surface of the throat bottom.

La surface de fond de gorge pourra être sensiblement inscrite sur un cone et éventuellement sur un cylindre dont l'axe est compris dans un plan perpendiculaire audit axe longitudinal, et la surface osculatrice pourra être conique.The throat bottom surface may be substantially inscribed on a cone and possibly on a cylinder whose axis is included in a plane perpendicular to said longitudinal axis, and the osculating surface may be conical.

La surface de fond de gorge pourra être sensiblement perpendiculaire à ladite surface latérale et la surface osculatrice pourra être sensiblement perpendiculaire à la surface annulaire.The bottom of throat surface may be substantially perpendicular to said lateral surface and the osculating surface may be substantially perpendicular to the annular surface.

La roue pourra comporter un revêtement de matériau antiadhérent sur les surfaces annulaire et/ou osculatrice adaptées à coopérer respectivement avec les surfaces latérale et/ou de fond de gorge de l'élément allongé.The wheel may include a coating of non-stick material on the annular and / or osculating surfaces adapted to cooperate respectively with the lateral and / or bottom groove surfaces of the elongated element.

L'élément allongé pourra être appliqué contre ladite roue par au moins un rouleau presseur.The elongate element can be applied against said wheel by at least one pressure roller.

Les moyens d'enduction pourront comporter deux rouleaux mélangeurs entre lesquels est disposée de la colle, l'un au moins des rouleaux étant enduit de colle sur une partie de sa surface extérieure, la roue étant en contact avec ledit rouleau enduit de colle.The coating means may comprise two mixing rollers between which glue is placed, at least one of the rollers being coated with glue on a part of its outer surface, the wheel being in contact with said roller coated with glue.

L'élément pourra comporter plusieurs surfaces latérales parallèles entre elles et la roue pourra comporter autant de surfaces annulaires latérales, adaptées à coopérer avec lesdites surfaces latérales de l'élément allongé, qu'il est nécessaire pour les encoller.The element may comprise several lateral surfaces parallel to each other and the wheel may comprise as many lateral annular surfaces, adapted to cooperate with said lateral surfaces of the elongated element, as is necessary for gluing them.

Au moins une des surfaces latérales de l'élément allongé pourra être plane et au moins une des surfaces annulaires, adaptées à coopérer avec les surfaces latérales de l'élément, pourra être plane et perpendiculaire à l'axe de la roue.At least one of the side surfaces of the elongate element may be planar and at least one of the annular surfaces, adapted to cooperate with the side surfaces of the element, may be planar and perpendicular to the axis of the wheel.

L'invention fournit également un procédé d'encollage d'un élément allongé profilé ayant un axe longitudinal, et comportant au moins une surface latérale et parallèle audit axe longitudinal. Ce procédé est notamment caractérisé en ce qu'il comporte les étapes suivantes :

  • on utilise une roue ayant un axe et ladite roue comportant au moins une surface latérale annulaire sensiblement perpendiculaire à l'axe de la roue et centrée sur ledit axe, ladite surface annulaire ayant un pourtour extérieur,
  • on déplace ledit élément allongé profilé relativement à la roue suivant un plan parallèle audit axe longitudinal dudit élément,
  • on enduit au moins ledit pourtour extérieur d'au moins une des surfaces annulaires de la roue avec de la colle, et
  • on applique la colle sur l'élément allongé profilé en faisant coopérer le pourtour extérieur de ladite surface annulaire et de ladite surface latérale de l'élément allongé.
The invention also provides a method of gluing an elongated profiled element having a longitudinal axis, and comprising at least one lateral surface and parallel to said longitudinal axis. This process is particularly characterized in that it comprises the following stages:
  • a wheel is used having an axis and said wheel comprising at least one annular lateral surface substantially perpendicular to the axis of the wheel and centered on said axis, said annular surface having an outer periphery,
  • said elongated profiled element is displaced relative to the wheel along a plane parallel to said longitudinal axis of said element,
  • at least said outer periphery is coated with at least one of the annular surfaces of the wheel with glue, and
  • the adhesive is applied to the profiled elongated element by making the outer periphery of said annular surface and said lateral surface of the elongated element cooperate.

L'invention fournit aussi un dispositif d'encollage d'un élément allongé ayant un axe longitudinal et une surface du fond de gorge devant être encollée.The invention also provides a device for sizing an elongated element having a longitudinal axis and a surface of the bottom of the groove to be glued.

Ce dispositif est notamment caractérisé en ce qu'il comporte une roue et des moyens d'enduction, ladite roue ayant une surface circonférentielle osculatrice de la surface du fond de gorge, les moyens d'enduction comportant deux rouleaux mélangeurs adaptés à produire un film de colle et en ce qu'une partie du film de colle est transférée par la surface osculatrice sur la surface du fond de gorge, par le contact de la roue sur un des deux rouleaux mélangeurs.This device is particularly characterized in that it comprises a wheel and coating means, said wheel having a circumferential osculating surface of the surface of the groove bottom, the coating means comprising two mixing rollers adapted to produce a film of glue and in that part of the glue film is transferred by the osculating surface onto the surface of the groove bottom, by the contact of the wheel on one of the two mixing rollers.

L'invention sera mieux comprise et ses avantages apparaîtront plus clairement à la description qui suit d'un exemple de réalisation illustré par les figures annexées où :

  • la figure 1 est une vue de face du dispositif en cours de fonctionnement,
  • la figure 2 est une vue de dessus du dispositif selon l'invention,
  • la figure 3 est une vue de profil de la roue encolleuse.
The invention will be better understood and its advantages will appear more clearly on the following description of an exemplary embodiment illustrated by the appended figures where:
  • FIG. 1 is a front view of the device during operation,
  • FIG. 2 is a top view of the device according to the invention,
  • Figure 3 is a side view of the gluing wheel.

Sur la figure 1, l'élément allongé profilé 1 à encoller est pénétré par la roue encolleuse 2 et maintenu sur cette dernière par un rouleau presseur 3.In FIG. 1, the elongated profiled element 1 to be glued is penetrated by the gluing wheel 2 and held thereon by a pressure roller 3.

La roue encolleuse 2 est animée d'un mouvement continu de rotation, autour de l'axe 5, par contact avec les moyens d'enduction 4, alors que l'élément allongé est animé d'une translation de sens correspondant sensiblement à celui de la vitesse tangentielle au niveau du contact entre la roue 2 et l'élément 1.The gluing wheel 2 is driven by a continuous rotational movement, around the axis 5, by contact with the coating means 4, while the elongated element is driven in a direction translation corresponding substantially to that of the tangential speed at the contact between the wheel 2 and the item 1.

La roue 2 comporte deux surfaces annulaires latérales 6 planes sensiblement perpendiculaires à l'axe 5 de la roue. Une partie de ces surfaces annulaires 6 coopèrent avec des surfaces latérales planes 7 (Fig. 3) dudit élément 1, ces surfaces latérales planes s'étendant suivant l'axe longitudinal de l'élément 1.The wheel 2 has two flat annular lateral surfaces 6 substantially perpendicular to the axis 5 of the wheel. A part of these annular surfaces 6 cooperate with planar lateral surfaces 7 (FIG. 3) of said element 1, these planar lateral surfaces extending along the longitudinal axis of element 1.

Ces surfaces annulaires 6 sont placées de part et d'autre de la roue encolleuse 2 et les surfaces latérales planes 7 de l'élément sont placées en vis-à-vis.These annular surfaces 6 are placed on either side of the gluing wheel 2 and the planar lateral surfaces 7 of the element are placed opposite.

La surface extérieure de la roue 2, ou surface osculatrice circonférentielle 8, est adaptée à coopérer avec l'élément allongé profilé 1 suivant une surface 9 du fond de gorge disposée perpendiculairement aux deux surfaces latérales planes et formant avec ces dernières les parois intérieures d'une gorge en U de l'élément allongé.The outer surface of the wheel 2, or circumferential osculating surface 8, is adapted to cooperate with the elongated profiled element 1 along a surface 9 of the groove bottom arranged perpendicular to the two flat lateral surfaces and forming with the latter the inner walls of a U-shaped groove of the elongated element.

La roue encolleuse 2 comporte sur ses parois latérales deux flasques 10 destinés à maintenir et/ou guider la roue 2 pour assurer notamment sa bonne coopération avec l'élément 1, son bon entraînement et son bon encollage au niveau des moyens d'enduction 4.The gluing wheel 2 has on its side walls two flanges 10 intended to hold and / or guide the wheel 2 in particular to ensure its good cooperation with the element 1, its good drive and its good gluing at the level of the coating means 4.

Les moyens d'enduction 4 comportent deux rouleaux mélangeurs 11, 12 synchronisés en rotation par un train d'engrenages 13 (Fig. 2) et entraînés par un groupe moto-réducteur 14 (Fig. 2).The coating means 4 comprise two mixing rollers 11, 12 synchronized in rotation by a gear train 13 (Fig. 2) and driven by a geared motor group 14 (Fig. 2).

Au-dessus et entre ces rouleaux mélangeurs 11 et 12 tournant en sens contraire et à même vitesse, est disposée une masse de colle 15 destinée à l'encollage.Above and between these mixing rollers 11 and 12 rotating in opposite directions and at the same speed, is placed a mass of adhesive 15 intended for gluing.

Cette masse de colle 15, qui peut être liquide, pâteuse, voire solide, est maintenue à l'intérieur de l'espace supérieur inter-rouleaux par deux centreurs ou organes limite-gomme 16 (Fig. 2).This mass of glue 15, which can be liquid, pasty, or even solid, is maintained inside the upper inter-roller space by two centralizers or rubber-limiting members 16 (FIG. 2).

L'élément allongé flexible est débité à partir d'une bobine 17 (Fig. 2), acheminé vers la roue encolleuse 2, puis dégagé, une fois enduit, vers la bobine réceptrice 18.The flexible elongate element is delivered from a reel 17 (FIG. 2), conveyed to the gluing wheel 2, then released, once coated, towards the take-up reel 18.

Le procédé d'encollage des surfaces latérales planes 7 et de la surface du fond de gorge 9 du profilé, s'effectue comme suit : la masse de colle 15 placée entre les rouleaux mélangeurs 11 et 12 y est laminée par ceux-ci en une couche très fine qui adhère aux rouleaux. Une partie de la fine couche de colle est ensuite reprise par la surface osculatrice 8 de la roue encolleuse 2, éventuellement par une légère pression de contact entre la roue 2 et l'un des rouleaux 12.The gluing process of the flat lateral surfaces 7 and of the surface of the bottom of the groove 9 of the profile is carried out as follows: the mass of adhesive 15 placed between the mixing rollers 11 and 12 is laminated therewith in a very thin layer that adheres to the rollers. Part of the thin layer of glue is then taken up by the osculating surface 8 of the sizing wheel 2, possibly by a slight contact pressure between the wheel 2 and one of the rollers 12.

Il apparait sur les pourtours extérieurs des surfaces annulaires 6 un cordon cylindrique périphérique de colle 19 (Fig. 3) de quantité suffisante pour enduire les surfaces latérales 7 de l'élément profilé. Par la rotation de la roue 2, le cordon est ensuite acheminé vers les surfaces latérales 7 où il s'étale grâce aux surfaces annulaires 6 et aux mouvements combinés de la roue 2 et de l'élément 1.It appears on the outer edges of the annular surfaces 6 a peripheral cylindrical bead of glue 19 (Fig. 3) of sufficient quantity to coat the side surfaces 7 of the profiled element. By the rotation of the wheel 2, the cord is then conveyed to the lateral surfaces 7 where it spreads out thanks to the annular surfaces 6 and to the combined movements of the wheel 2 and of the element 1.

La taille du cordon résulte notamment de la combinaison de l'espacement des rouleaux mélangeurs 11, 12, définissant l'épaisseur du film de colle sur les rouleaux, de la nature et de la géométrie de la roue encolleuse, de sa pression de contact avec l'un 12 des rouleaux mélangeurs.The size of the bead results in particular from the combination of the spacing of the mixing rollers 11, 12, defining the thickness of the adhesive film on the rollers, the nature and the geometry of the gluing wheel, its contact pressure with one 12 of the mixing rollers.

La taille du cordon, comme les différentes vitesses relatives des éléments en mouvement et la géométrie de ceux-ci, détermine quant à elle l'épaisseur du film de colle sur les surfaces latérales 7 et du fond de gorge 9 de l'élément 1.The size of the bead, like the different relative speeds of the moving elements and the geometry of these, determines the thickness of the adhesive film on the lateral surfaces 7 and of the groove bottom 9 of the element 1.

Sans aucun caractère limitatif concernant la nature des éléments utilisés pour la mise en oeuvre du procédé, on pourra utiliser des rouleaux mélangeurs 11, 12, en acier ou en aluminium, des centreurs en téflon, une roue encolleuse 2 en caoutchouc silicone, téflon ou néoprène, renforcée par des flasques 10 métalliques pour encoller un élément allongé profilé en polyamide 11 (généralement désigné par la marque de fabrication Rilsan) avec par exemple la colle époxyde SCOTCH-WELD 2216 B/A qui est une marque déposée par la Société Minesota Mining and Manufacturing Co dans des proportions proposées par le fabricant.Without any limiting character concerning the nature of the elements used for the implementation of the process, one will be able to use mixing rollers 11, 12, in steel or aluminum, centralizers in teflon, a gluing wheel 2 in silicone rubber, teflon or neoprene , reinforced by metal flanges 10 for gluing an elongated profiled polyamide 11 element (generally designated by the manufacturing brand Rilsan) with for example the epoxy adhesive SCOTCH-WELD 2216 B / A which is a trademark registered by the Company Minesota Mining and Manufacturing Co in proportions proposed by the manufacturer.

Par exemple, un cordon de diamètre 1/10ème à 1/100ème de millimètre permet d'obtenir des épaisseurs de colle suffisante sur une largeur d'une des surfaces latérales planes de l'élément de l'ordre du centimètre.For example, a bead with a diameter of 1 / 10th to 1 / 100th of a millimeter makes it possible to obtain sufficient thicknesses of glue over a width of one of the flat lateral surfaces of the element of the order of a centimeter.

Lorsque la surface de fond de gorge 9 n'est pas plane, il est possible, avec un matériau de la roue adapté, de donner à la surface osculatrice 8 une forme adaptée pour que cette surface puisse coopérer, d'une part, avec la surface du fond de gorge 9 et, d'autre part, avec la surface extérieure du rouleau mélangeur 12 avec laquelle elle entre en contact. Ainsi, l'association du choix de la dureté de la roue et de la forme de la surface osculatrice 9, permet à cette dernière 9 d'épouser à la fois la surface cylindrique de révolution du rouleau 12 et la surface du fond de gorge 9 non cylindrique.When the groove bottom surface 9 is not flat, it is possible, with a suitable wheel material, to give the osculating surface 8 a suitable shape so that this surface can cooperate, on the one hand, with the groove bottom surface 9 and, on the other hand, with the outer surface of the mixing roller 12 with which it comes into contact. Thus, the association of the choice of the hardness of the wheel and the shape of the osculating surface 9, allows the latter 9 to match both the cylindrical surface of revolution of the roller 12 and the surface of the groove bottom 9 not cylindrical.

Dans le mode de réalisation décrit, l'élément allongé 1 comporte deux surfaces latérales 7 planes perpendiculaires à la surface du fond de gorge 9 et la roue comporte deux surfaces annulaires 6 planes. On ne sortira pas du cadre de la présente invention lorsque au moins l'une des surfaces latérales n'est pas perpendiculaire à l'axe de la roue et lorsqu'elle pourra coopérer au moins avec un pourtour extérieur d'une surface annulaire, soit sans déformation de la roue 2 et/ou de l'élément 1, soit avec déformation de l'un et/ou de l'autre, notamment lorsqu'ils sont élastiques.In the embodiment described, the elongate element 1 comprises two lateral flat surfaces 7 perpendicular to the surface of the groove bottom 9 and the wheel comprises two annular surfaces 6 flat. It will not depart from the scope of the present invention when at least one of the lateral surfaces is not perpendicular to the axis of the wheel and when it can cooperate at least with an outer periphery of an annular surface, ie without deformation of the wheel 2 and / or of the element 1, or with deformation of one and / or the other, in particular when they are elastic.

Ainsi, les surfaces latérales de l'élément pourront avoir tendance, soit à fermer l'élément, soit à l'ouvrir.Thus, the lateral surfaces of the element may have a tendency, either to close the element, or to open it.

De même, la ou les surfaces annulaires ne seront pas nécessairement planes et pourront être tronconiques. Le sommet du cône sur lequel s'appuie la surface annulaire, qui est sur l'axe 5 de la roue 2 pourra être, soit d'un côté, soit de l'autre du plan dans lequel se trouve le contour extérieur de la surface annulaire.Likewise, the annular surface or surfaces will not necessarily be planar and may be frustoconical. The apex of the cone on which the annular surface rests, which is on the axis 5 of the wheel 2 may be either on one side or the other of the plane in which the outer contour of the surface is located. annular.

Le matériau de la roue pourra permettre une adaptation de la surface annulaire 6 à la surface latérale 7 par une déformation de la roue et/ou du profilé 1, notamment au niveau du contact de la roue 2 avec le profilé 1..The material of the wheel may allow adaptation of the annular surface 6 to the lateral surface 7 by a deformation of the wheel and / or of the profile 1, in particular at the level of the contact of the wheel 2 with the profile 1.

La surface annulaire pourra être composée de tronçons de cônes et pourra aussi revêtir des formes variées permettant son adaptation aux surfaces latérales du profilé.The annular surface may be composed of sections of cones and may also take various shapes allowing it to be adapted to the lateral surfaces of the profile.

Par exemple, lorsque le profilé comporte au moins une surface latérale 7 perpendiculaire à l'axe 5 et lorsque la roue comporte une surface annulaire 6 conique en creux (par opposition au relief), l'enduction de la surface latérale 7 s'effectuera par le contour extérieur de cette surface annulaire 6.For example, when the profile has at least one lateral surface 7 perpendicular to the axis 5 and when the wheel has a hollow conical annular surface 6 (as opposed to the relief), the coating of the lateral surface 7 will be carried out by the outer contour of this annular surface 6.

D'une manière générale, pour procéder à un bon encollage des surfaces latérales des profilés, il est nécessaire que les pourtours extérieurs des surfaces annulaires de la roue soient à toute proximité, voire même touchent, grâce à un serrage approprié, les surfaces latérales à encoller.In general, to glue the lateral surfaces of the profiles properly, it is necessary for the outer edges of the annular surfaces of the wheel to be very close to, or even touch, by means of appropriate clamping, the lateral surfaces to paste.

Selon le même procédé, on pourra encoller autant de surfaces latérales 7 que l'on désirera, comme cela peut être le cas pour un élément profilé comportant plusieurs gorges parallèles.According to the same method, it is possible to glue as many side surfaces 7 as desired, as may be the case for a profiled element comprising several parallel grooves.

On pourra aussi, en empêchant le pourtour de la surface annulaire 6 d'être alimenté par un cordon de colle 19, ne pas réaliser d'encollage sur une surface latérale de l'élément allongé.It is also possible, by preventing the periphery of the annular surface 6 from being supplied by a bead of glue 19, not to carry out gluing on a lateral surface of the elongated element.

On pourra utiliser des racloirs disposés sur les rouleaux mélangeurs pour concentrer ou disperser la colle au voisinage de la surface osculatrice de la roue ou des pourtours, de manière que le cordon ait des dimensions correctes.It is possible to use scrapers placed on the mixing rollers to concentrate or disperse the glue in the vicinity of the osculating surface of the wheel or the edges, so that the bead has the correct dimensions.

Les moyens d'enduction pourront exclure des rouleaux mélangeurs.The coating means may exclude mixing rollers.

On pourra encoller seulement la surface du fond de gorge de l'élément profilé et on pourra utiliser des rouleaux mélangeurs à cette fin.We can only glue the surface of the groove bottom of the profiled element and we can use mixing rollers for this purpose.

On pourra presser l'élément profilé contre la roue encolleuse par plusieurs rouleaux presseurs.The profiled element can be pressed against the gluing wheel by several pressing rollers.

Les rouleaux mélangeurs des moyens d'enduction pourront ne pas être synchronisés en rotation entre eux et/ou avec la roue encolleuse, ou être synchronisés à des vitesses différentes pour obtenir un effet de friction lorsqu'un tel effet a des conséquences bénéfiques.The mixing rollers of the coating means may not be synchronized in rotation with one another and / or with the gluing wheel, or may be synchronized at different speeds to obtain a friction effect when such an effect has beneficial consequences.

On pourra, notamment au niveau de son contact avec la roue encolleuse, guider transversalement l'élément profilé au moyen de rouleaux s'appuyant sur les faces latérales de l'élément.It will be possible, in particular at its contact with the gluing wheel, to guide the profiled element transversely by means of rollers bearing on the lateral faces of the element.
