Abstract

The lightweight corrugated roofing material, e.g. of a bitumen-impregnated cellulose material, a plastic such as PVC or of steel, is designed to be used on its own or as a support for flat or channelled tiles, and has corrugations (2) with transverse recesses (3) at intervals for the tiles to engage with. The amplitude and pitch of the corrugations are in a ratio of between 1 : 1 and 1 : 2, and the upper surfaces of their crests, which are slightly flattened, are roughened, having projections between 0.1 and 0.9 mm high and at a rate of between 1 and 100 per sq cm.

Description

L'invention est relative à un matériau de couverture. Ce matériau peut constituer une toiture légère ou être utilisé pour réaliser une sous-toiture destinée à un toit en tuiles rondes avec ou sans tenons ou en tuiles plates, dites « marseillaises ».The invention relates to a roofing material. This material can constitute a light roof or be used to make a roofing for a roof in round tiles with or without studs or in flat tiles, say "Marseille".

On connaít des sous-toitures réalisées en des matériaux profilés, notamment ondulés et présentant, dans certains cas, une alternance d'ondes et de zones plates. Le brevet FR-2 496 551 décrit des matériaux de ce type.We know roofing made of materials profiles, in particular corrugated and having, in certain case, alternating waves and flat areas. The patent FR-2 496 551 describes materials of this type.

Un tel matériau profilé peut également permettre de réaliser des toitures légères.Such a profiled material can also make it possible to make light roofs.

Par ailleurs, les matériaux de sous-toiture ondulés sont plus particulièrement destinés à des tuiles canal. Ils présentent de grandes qualités puisqu'ils rendent la toiture étanche, même si une tuile se déplace ou casse, et garantissent une ventilation naturelle de celle-ci.In addition, corrugated roofing materials are more particularly intended for channel tiles. They have great qualities since they make the waterproof roof, even if a tile moves or breaks, and guarantee a natural ventilation of it.

C'est pourquoi des plaques ondulées ont également été utilisées pour réaliser des sous-toitures destinées à des toits de tuiles plates.This is why corrugated sheets have also been used to make roofing for flat tile roofs.

Pour pouvoir accrocher les tuiles plates, il est tout d'abord nécessaire de fixer des liteaux sur la sous-toiture, les liteaux servant à l'accrochage des tuiles.To be able to hang the flat tiles, it's all first necessary to fix battens on the sub-roof, the battens used to hang the tiles.

La fixation de liteaux sur les plaques ondulées présente cependant des inconvénients. En particulier, le poids des liteaux et des tuiles est presque entièrement porté par le sommet des ondulations qui ont tendance à se déformer.The fixing of battens on the corrugated sheets has drawbacks, however. In particular, the weight of battens and tiles is almost entirely carried by the top of the undulations which tend to deform.

Ceci fragilise la sous-toiture. De surcroít, la déformation de la sous-toiture peut compromettre une bonne ventilation de la toiture et empêcher l'écoulement de l'eau, éventuellement infiltrée à travers une tuile défectueuse.This weakens the roofing. In addition, the deformation of the roofing can compromise good ventilation of the roof and prevent the flow of water, possibly infiltrated through a tile defective.

C'est pourquoi ont été conçus des éléments de support et de répartition de charges, destinés à être interposés entre les liteaux et la sous-toiture, à intervalles déterminés.This is why support elements have been designed and load distribution, intended to be interposed between the battens and the roofing, at intervals determined.

On peut citer, à cet égard, le brevet FR-2 658 848 qui décrit un élément de support et de répartition de charges constitué d'une entretoise tubulaire disposée dans une ondulation concave de la sous-toiture. Un tel élément permet de bien répartir les charges et de ne pas empêcher le passage de l'air de ventilation de la toiture.Mention may be made, in this regard, of patent FR-2 658 848 which describes a support and load distribution element consisting of a tubular spacer arranged in a concave undulation of the roofing. Such an element allows to distribute the loads well and not to prevent the passage of ventilation air from the roof.

Cependant, la présence des liteaux et des éléments de support et de répartition de charges allonge le temps de réalisation des toitures et intervient de façon non négligeable dans leur coût. Ils peuvent également bloquer, au moins en partie, le passage de l'air entre les tuiles et la sous-toiture, ainsi que l'écoulement de l'eau.However, the presence of battens and elements of support and load distribution lengthens the time realization of roofs and intervenes in a non- negligible in their cost. They can also block, at least in part, the passage of air between the tiles and the roofing, as well as the water flow.

Il est par ailleurs souhaitable de simplifier la réalisation des toitures en tuiles plates.It is also desirable to simplify the realization of flat tile roofs.

Il est également apparu nécessaire de rendre les matériaux profilés plus rigides, qu'ils soient destinés à être utilisés en tant que matériau de toiture ou de sous-toiture, pour accroítre la durée de vie de la toiture.It also appeared necessary to make the more rigid profiled materials, whether intended for be used as roofing or under-roofing material, to increase the life of the roof.

Un matériau de couverture présentant des ondulations est connu du document GB-A-613845. Ce matériau de couverture comporte, sur une de ses surfaces, des zones en creux dans la partie convexe des ondulations pour l'accrochage des tuiles.A roofing material with undulations is known from document GB-A-613845. This cover material has recessed areas on one of its surfaces convex undulations for hanging tiles.

L'invention est ainsi relative à un matériau de couverture présentant des ondulations et comportant, sur une de ses surfaces, des zones en creux dans la partie convexe des ondulations pour l'accrochage de tuiles. Ce matériau présente sur le sommet de la partie convexe des ondulations un état de surface rugueux obtenu par des aspérités avec les caractéristiques énoncées dans la revendication 1.The invention thus relates to a roofing material having undulations and having, on one of its surfaces, recessed areas in the convex part of the corrugations for hanging tiles. This material present on the top of the convex part of the corrugations a rough surface finish obtained asperities with the features set out in claim 1.

Ceci contribue à éviter le glissement des tuiles.This helps to prevent the tiles from sliding.

Ces zones en creux permettent l'accrochage des tuiles plates directement sur le matériau de sous-toiture. La présence de liteaux et d'éléments de support et de répartition de charges est ainsi rendue inutile.These recessed areas allow the hanging of the tiles flat directly on the roofing material. The presence of battens and support elements and burden sharing is thus rendered unnecessary.

L'économie de bois de charpente est estimée à environ 70 % du coût total.The lumber economy is estimated to be approximately 70% of the total cost.

De préférence, le rapport entre l'amplitude des ondulations et leur pas est compris entre environ 1/2 et Preferably, the ratio between the amplitude of the ripples and their pitch is between about 1/2 and

Ce matériau de couverture présente alors des ondes plus profondes, ce qui accroít sa résistance au fléchissement et la solidité des toitures dans lesquelles il est utilisé, qu'il soit utilisé en tant que sous-toiture ou directement pour réaliser une toiture légère.This covering material then presents more waves deep, which increases its resistance to sagging and the strength of the roofs in which it is used, whether used as an underlay or directly to make a light roof.

Ces ondes profondes permettent aussi un parfait drainage.These deep waves also allow a perfect drainage.

Les zones en creux sont avantageusement réparties selon des droites sensiblement perpendiculaires aux ondulations.The hollow areas are advantageously distributed according to straight lines substantially perpendicular to the undulations.

Par ailleurs, également sur la surface du matériau destinée à recevoir les tuiles, le sommet de la partie convexe des ondulations est, de préférence, légèrement aplati.Furthermore, also on the surface of the material intended to receive the tiles, the top of the game convex ripples is preferably slightly flattened.

Ceci permet d'assurer une surface de contact étendue entre les tuiles plates et le sommet des ondulations et d'éviter ainsi tout risque de déformation de la sous-toiture et de glissement des tuiles.This ensures an extended contact surface between the flat tiles and the top of the ripples and thus avoiding any risk of deformation of the roofing and sliding the tiles.

Pour réaliser des sous-toitures pour des tuiles canal, le matériau de couverture présente avantageusement une alternance de zones plates et d'ondulations. Les zones plates permettent de mieux caler les tuiles de courant ou les tuiles de couvert, quand les tuiles de courant sont supprimées.To make roofing for channel tiles, the covering material advantageously has a alternating flat areas and undulations. The areas plates allow better wedging of the current tiles or the roof tiles, when the current tiles are deleted.

Ce matériau est plus particulièrement destiné à la réalisation de toitures en tuiles plates. Il constitue alors une sous-toiture supportant directement les tuiles plates. Le tenon de chaque tuile plate est reçu par une zone en creux du matériau.This material is more particularly intended for the realization of flat tile roofs. He makes then a roofing directly supporting the tiles flat. The tenon of each flat tile is received by a hollow area of the material.

En référence à la figure 1, le matériau de couverture 1 présente la forme d'une plaque ondulée. Le profil de la plaque est une ondulation régulière sensiblement sinusoïdale. Il pourrait également présenter une alternance d'ondes et de zones plates. Par ailleurs, les ondulations pourraient être différentes, par exemple de type grec ou en V. Referring to Figure 1, the cover material 1 has the shape of a corrugated plate. The profile of the plate is a regular ripple substantially sinusoidal. It could also present an alternation waves and flat areas. In addition, the ripples could be different, for example of Greek type or in V.

Le matériau de couverture illustré à la figure 1 est plus particulièrement destiné à la réalisation d'une sous-toiture pour un toit en tuiles plates.The roofing material shown in Figure 1 is more particularly intended for the realization of an under-roof for a flat tile roof.

Il comporte, sur sa surface destinée à recevoir les tuiles, des zones en creux 3 qui sont ménagées sur la partie convexe 10 de chaque ondulation 2 et réparties selon des droites parallèles entre elles et perpendiculaires aux ondulations 2.It has, on its surface intended to receive the tiles, hollow areas 3 which are formed on the convex part 10 of each corrugation 2 and distributed according to lines parallel to each other and perpendicular to ripples 2.

Comme l'illustre la figure 6, ces zones en creux doivent permettre d'accrocher directement les tuiles plates sur la plaque ondulée 1. Leur profondeur est donc choisie pour pouvoir recevoir et retenir les tenons 7 des tuiles 6. Leur fond 9 est, de préférence, plat. Les faces hautes et basses de ces zones en creux sont avantageusement inclinées par rapport au fond 9, ces inclinaisons étant avantageusement symétriques par rapport à un plan perpendiculaire au fond de ces zones.As illustrated in Figure 6, these recessed areas must allow direct hanging of flat tiles on the corrugated plate 1. Their depth is therefore chosen to be able to receive and retain the studs 7 of the tiles 6. Their bottom 9 is preferably flat. The high sides and of these recessed areas are advantageously inclined relative to the bottom 9, these inclinations being advantageously symmetrical with respect to a plane perpendicular to the bottom of these areas.

La distance entre les zones en creux est adaptée au type de tuiles utilisé pour la toiture.The distance between the recessed areas is adapted to the type of tiles used for roofing.

La toiture est alors réalisée de la façon suivante :The roof is then carried out as follows:

Des plaques ondulées, comme la plaque 1, sont fixées sur la charpente 4 de façon à ce qu'elles se recouvrent partiellement et que les ondulations 2 soient placées selon la pente du toit. Tout moyen de fixation 5 approprié, placé de préférence sur le sommet des ondulations, peut être utilisé.Corrugated plates, like plate 1, are attached on frame 4 so that they overlap partially and that the corrugations 2 are placed according to the slope of the roof. Any suitable fastening means 5 placed preferably on the top of the undulations, can be used.

Les tuiles plates 6 sont ensuite directement posées sur la sous-toiture formée par les plaques ondulées, les zones en creux 3 recevant les tenons 7.The flat tiles 6 are then placed directly on the roofing formed by the corrugated sheets, the zones hollow 3 receiving the studs 7.

Les zones en creux évitent le glissement des tuiles, les liteaux étant supprimés. Elles simplifient également le travail du couvreur, puisqu'elles assurent un alignement parfait sans le recours à une corde. The recessed areas prevent the tiles from sliding, the battens being deleted. They also simplify the work of the roofer, since they ensure alignment perfect without the use of a rope.

Par ailleurs, le sommet 8 des ondulations 2 est, de préférence, légèrement aplati et le matériau 1 présente un profil semi-trapézoïdal, comme illustré par les figures 4 et 5.Furthermore, the top 8 of the undulations 2 is, of preferably slightly flattened and material 1 has a semi-trapezoidal profile, as shown in Figures 4 and 5.

Ce profil renforce la résistance du matériau selon l'invention et offre une surface de contact importante entre les tuiles plates et le sommet des ondulations. En particulier, le matériau n'est pas déformé lorsque l'on marche dessus, il résiste au poids des tuiles et soutient parfaitement la toiture.This profile strengthens the resistance of the material according to the invention and offers a large contact surface between the flat tiles and the top of the undulations. In particular, the material is not deformed when step on it, it resists the weight of the tiles and supports the roof perfectly.

Pour améliorer l'accrochage des tuiles sur le matériau, celui-ci comporte avantageusement un état de surface rugueux sur le sommet 8 de la partie convexe 10 des ondulations 2.To improve the fixing of tiles on the material, this advantageously comprises a state of rough surface on the top 8 of the convex part 10 of the ripples 2.

De façon avantageuse, le rapport entre l'amplitude de l'onde et le pas des ondulations est compris entre environ 1/2 et 1/1. A titre de comparaison, le rapport amplitude/pas pour un matériau profilé classique est de 36/95, soit environ 1/2,6.Advantageously, the ratio between the amplitude of the wave and the pitch of the undulations is between approximately 1/2 and 1/1. For comparison, the report amplitude / pitch for a conventional profiled material is 36/95, or approximately 1 / 2.6.

L'amplitude de l'onde est alors, pour un pas déterminé, supérieure à celle d'une plaque ondulée classique, du type décrit dans le brevet FR-2 496 551. La résistance au fléchissement de la plaque est ainsi également augmentée.The amplitude of the wave is then, for a determined step, superior to that of a conventional corrugated sheet, of the type described in patent FR-2,496,551. Resistance to sagging of the plate is thus also increased.

A titre d'exemple, lorsque le rapport amplitude/pas augmente d'environ 5,5 %, l'inertie du matériau augmente de 15,5 %.For example, when the amplitude / pitch ratio increases by about 5.5%, the inertia of the material increases by 15.5%.

Dans un matériau conforme à l'invention, l'amplitude de l'onde sera par exemple de 24 mm et le pas de 49 mm, pour une épaisseur comprise entre 2 et 3mm.In a material according to the invention, the amplitude of the wave will be for example 24 mm and the pitch of 49 mm, for a thickness between 2 and 3mm.

Un état de surface rugueux bien adapté pourra être réalisé par gaufrage. De bons résultats ont été obtenus avec des aspérités de quelques dixièmes de millimètre de hauteur ayant une base inscrite dans un cercle de diamètre compris entre 0,1 à 0,9 mm de côté. Ces aspérités sont avantageusement au nombre de 1 à 100 par cm2 (10-4 m2).A rough surface which is well suited can be produced by embossing. Good results have been obtained with roughness a few tenths of a millimeter in height having a base inscribed in a circle with a diameter of between 0.1 and 0.9 mm on a side. These asperities are advantageously 1 to 100 per cm 2 (10 -4 m 2 ).

Le matériau de couverture 1 est ainsi plus rigide, qu'il soit utilisé pour réaliser une toiture légère, avec une finition de surface adaptée, ou pour former une sous-toiture, pour un toit en tuiles plates ou canal.The covering material 1 is thus more rigid, be used to make a light roof, with a suitable surface finish, or to form an under-roof, for a flat or canal tile roof.

Le matériau de couverture selon l'invention peut par exemple être réalisé en une matière cellulosique imprégnée de bitume, en une matière plastique, du type PVC ou encore en acier. Les matériaux de couverture en plastique présentent une meilleure stabilité dimensionnelle et une résistance à l'humidité améliorée.The covering material according to the invention can by example be made of an impregnated cellulosic material bitumen, plastic, PVC type or in steel. Plastic roofing materials have better dimensional stability and improved moisture resistance.

Le matériau de couverture est avantageusement fabriqué à l'aide d'une machine ondulatrice formant les ondulations puis d'une machine de reprofilage pour la formation des zones en creux.The covering material is advantageously made using an undulating machine forming the undulations then a reprofiling machine for the formation of hollow areas.

En référence à la figure 7, la machine pour l'ondulation du matériau de couverture de l'invention comprend un bâti 101 dans lequel sont montées les barres ondulatrices 106.Referring to Figure 7, the machine for the corrugation of the covering material of the invention includes a frame 101 in which the bars are mounted inverters 106.

Le matériau à onduler 110 provient d'un système non représenté sur la figure. Il est guidé par des moyens appropriés 111 et 112 sur les barres 113 de la chaíne 114 du séchoir.The material to be corrugated 110 comes from a non-corrugated system. shown in the figure. He is guided by means suitable 111 and 112 on bars 113 of chain 114 of the dryer.

Il est généralement constitué par une feuille de matière malléable telle que carton humide ou feutre.It generally consists of a sheet of malleable material such as wet cardboard or felt.

En sortie de la machine à onduler, le matériau profilé est amené à l'entrée 115 du séchoir tunnel 116. Quand il sort du séchoir, le matériau profilé est retiré des barres du séchoir. Le sens de la circulation du matériau sur la chaíne 114 du séchoir est indiqué par la flèche F.At the outlet of the corrugating machine, the profiled material is brought to entrance 115 of tunnel dryer 116. When it comes out of the dryer, the profiled material is removed from the bars of the dryer. The direction of flow of the material on the chain 114 of the dryer is indicated by the arrow F.

Dans le bâti 101, sont montés deux paliers 102. Chacun des paliers est traversé par un arbre 103 entraíné en rotation par un moteur non représenté sur la figure. Les arbres 102 sont parallèles et entraínent en rotation une chaíne sans fin 105, par l'intermédiaire d'organes de transmission 145.In the frame 101, two bearings 102 are mounted. Each bearings is crossed by a tree 103 driven in rotation by a motor not shown in the figure. The shafts 102 are parallel and rotate endless chain 105, through transmission 145.

Des barres ondulatrices 106 sont fixées sur la chaíne par l'intermédiaire d'un support 107. Elles sont mobiles en translation par rapport au plan de la chaíne, comme cela sera décrit plus en détail au regard de la figure 8.Waving bars 106 are fixed on the chain via a support 107. They are movable in translation relative to the plane of the chain, like this will be described in more detail with reference to FIG. 8.

De préférence, l'ensemble constitué par la chaíne sans fin 105 et les barres ondulatrices 106 est fixé sur un bâti intermédiaire 108, lui-même fixé au bâti 101. Le bâti intermédiaire est monté coulissant sur des glissières.Preferably, the assembly constituted by the chain without end 105 and the waving bars 106 is fixed on a frame intermediate 108, itself fixed to the frame 101. The frame intermediate is slidably mounted on slides.

Ceci permet de régler la distance entre les barres ondulatrices 106 et les barres 113 du séchoir.This allows you to adjust the distance between the bars corrugators 106 and the bars 113 of the dryer.

Sous les barres du séchoir, la machine à onduler comporte de préférence une autre chaíne sans fin 117. Elle est entraínée en rotation par l'intermédiaire de deux arbres 118 portés par des paliers 119, fixés sur le bâti 101. Les arbres 118 sont parallèles aux arbres 102.Under the dryer bars, the waving machine preferably includes another endless chain 117. It is rotated by two shafts 118 carried by bearings 119, fixed to the frame 101. The trees 118 are parallel to the trees 102.

Des barres de renfort 120 sont fixées sur la chaíne 117, parallèlement aux barres du séchoir.Reinforcement bars 120 are fixed on the chain 117, parallel to the dryer bars.

En référence à la figure 8, la feuille 110 de matériau à onduler est supportée par les barres 113 de la chaíne du séchoir. Elle est transformée entre les barres ondulatrices 106 et les barres 113. Le matériau 121 qui sort de la machine à onduler présente le profil correspondant à la machine et au réglage des barres ondulatrices.Referring to Figure 8, the sheet 110 of material to be waved is supported by the bars 113 of the chain of dryer. It is transformed between the waving bars 106 and the bars 113. The material 121 which leaves the corrugator has the profile corresponding to the machine and adjustment of the waving bars.

Dans l'exemple illustré à la figure 8, la machine à onduler comporte, en alternance, deux barres ondulatrices 106 de section ronde et une tige de maintien 122. Comme on le verra ultérieurement, les tiges de maintien permettent de former des zones plates. Le matériau 121 comporte ainsi une alternance de deux ondulations 123 et d'une zone plate 124. In the example illustrated in Figure 8, the machine waving has two waving bars alternately 106 of round section and a retaining rod 122. As is will see later, the holding rods allow to form flat areas. The material 121 thus comprises alternating two undulations 123 and a flat area 124.

Le fonctionnement de la machine ondulatrice est le suivant :The operation of the inverter machine is the next :

La feuille 110 de matériau à onduler est fournie en continu et vient se placer sur les barres 113 du séchoir qui défilent également en continu sur la chaíne 114 du séchoir.The sheet 110 of material to be corrugated is supplied in continuous and is placed on the bars 113 of the dryer who also parade continuously on chain 114 of dryer.

Une barre ondulatrice 106 est amenée par la chaíne sans fin 105 dans la partie 142 de la chaíne 105 où elle est en regard du plan des barres de support. Le support 107 de la barre ondulatrice est alors perpendiculaire au plan des barres 113 du séchoir. La barre ondulatrice se trouve en position haute et n'est pas en contact avec le matériau à onduler. Elle vient alors en regard d'une saillie 140 de la came, qui vient en appui sur l'élément 132.A waving bar 106 is brought by the chain without end 105 in part 142 of chain 105 where it is in look at the support bar plan. Support 107 of the wavy bar is then perpendicular to the plane of 113 bars of the dryer. The wavy bar is in high position and is not in contact with the material to be waving. It then comes opposite a projection 140 of the cam, which bears on element 132.

Du fait de la rotation de la came 135 autour de l'axe 136, la saillie 140 enfonce l'élément mobile 127 du support de la barre ondulatrice. La barre ondulatrice subit alors une translation, perpendiculairement au plan de la chaíne sans fin et à celui des barres de support et se trouve en position basse.Due to the rotation of the cam 135 around the axis 136, the projection 140 pushes the movable element 127 of the support of the wave bar. The wavy bar then undergoes a translation, perpendicular to the plane of the chain endless and to that of the support bars and is in low position.

Le déplacement de la chaíne 105 des barres ondulatrices et celui de la chaíne 114 du séchoir sont réglés l'un par rapport à l'autre, de façon à ce qu'une barre ondulatrice soit placée en position basse entre deux barres du séchoir. Le mouvement de la chape 130 comprime les moyens élastiques 134.The displacement of the chain 105 of the waving bars and that of chain 114 of the dryer are regulated one by relative to each other, so that a wavy bar is placed in the low position between two bars of the dryer. The movement of the yoke 130 compresses the elastic means 134.

Avant que le contact entre l'élément 132 du support de la barre ondulatrice et la saillie 140 ne prenne fin du fait du mouvement de rotation de la came 135, les roulements 132 viennent en contact avec la glissière 137, la barre ondulatrice étant entraínée par la chaíne sans fin 105 dans la direction de défilement du matériau à onduler.Before contact between element 132 of the support the wave bar and the projection 140 does not end at made of the rotation movement of the cam 135, the bearings 132 come into contact with slide 137, the wave bar being driven by the endless chain 105 in the direction of travel of the material to be corrugated.

La barre ondulatrice 106 est ainsi maintenue en position basse tant que les roulements 132 sont en contact avec la première zone 138 de la glissière, parallèle au plan des barres 113 du séchoir.The corrugator bar 106 is thus maintained in low position as long as the bearings 132 are in contact with the first zone 138 of the slide, parallel to the plan of the bars 113 of the dryer.

Ensuite, les roulements 132 s'engagent dans la deuxième zone 139 de la glissière. En sortie de cette deuxième zone, la barre ondulatrice 106 se trouve de nouveau en position haute.Then, the bearings 132 engage in the second zone 139 of the slide. On leaving this second zone, the corrugator bar 106 is again in position high.

La pression sur l'élément 132 se relâchant, le ressort 134, préalablement comprimé, se détend. L'élément mobile 127 subit alors un mouvement de translation qui l'éloigne du plan des barres 113 du séchoir. Le mouvement entraíne la remontée de la barre ondulatrice qui se trouve dégagée des barres du séchoir entre lesquelles elle pénétrait.The pressure on the element 132 relaxing, the spring 134, previously compressed, relaxes. The moving element 127 then undergoes a translational movement which moves it away of the plane of the bars 113 of the dryer. The movement is rise of the corrugator bar which is clear of bars of the dryer between which it penetrated.

La barre ondulatrice est ensuite entraínée par la chaíne sans fin.The corrugator bar is then driven by the endless chain.

Les positions de la came 135 et de la glissière 137 sont, de préférence, choisies de façon à maintenir les barres ondulatrices 106 en contact avec le matériau à onduler, tant que la chaíne 105 est parallèle au plan des barres du séchoir.The positions of the cam 135 and the slide 137 are preferably chosen so as to maintain the waving bars 106 in contact with the material to be undulate, as long as the chain 105 is parallel to the plane of dryer bars.

Ceci permet d'escamoter facilement les barres ondulatrices dont le support est perpendiculaire au plan du séchoir, tout en maintenant suffisamment longtemps les barres ondulatrices en contact avec le matériau à onduler pour former le profil de façon stable et diminuer les contraintes.This allows the bars to be easily retracted undulators whose support is perpendicular to the plane of the dryer, while keeping the corrugating bars in contact with the material to be corrugated to form the profile stably and decrease constraints.

En référence à la figure 9, la machine de reprofilage du matériau de couverture de l'invention comporte un premier bâti 201, supportant des barres 202 servant de formes pour reprofiler un matériau préalablement ondulé 203.Referring to Figure 9, the reprofiling machine of the covering material of the invention comprises a first frame 201, supporting bars 202 serving as shapes to reprofile a previously corrugated material 203.

La machine comprend également un deuxième bâti 204, sur lequel est monté un bloc 205, supportant des barres 206 servant de contre-formes. The machine also includes a second frame 204, on which is mounted a block 205, supporting bars 206 serving as counter-forms.

Le bloc 205 est monté coulissant sur des glissières fixées au bâti 204. Ceci permet de régler la distance entre les barres de reprofilage 202 et les barres de contre-forme 206.Block 205 is slidably mounted on slides fixed to the frame 204. This allows the distance between reshaping bars 202 and counter-form bars 206.

Le matériau est généralement constitué en carton humide, en feutre ou tout autre matière malléable.The material is generally made of cardboard damp, felt or any other malleable material.

Le matériau est amené, par un dispositif non représenté sur la figure, sur des barres de support 207. Les barres sont, de préférence, celles de la chaíne 208 du séchoir.The material is brought, by a device not shown in the figure, on support bars 207. The bars are, preferably, those of the chain 208 of the dryer.

Cette solution présente l'avantage d'éviter la manipulation des matériaux 209 qui sortent humides de la machine à reprofiler, avant leur entrée dans le séchoir tunnel 210.This solution has the advantage of avoiding the handling of materials 209 which come out wet from the reprofiling machine, before entering the dryer tunnel 210.

Ceci limite les risques de détérioration du produit et réduit les coûts de mise en oeuvre.This limits the risk of product deterioration and reduces implementation costs.

Les matériaux sont retirés des barres de support 207, lorsqu'ils sortent du séchoir 210. Le sens de la circulation des matériaux 209 sur la chaíne 208 du séchoir est indiqué par la flèche F.The materials are removed from the support bars 207, when they come out of dryer 210. The sense of circulation of materials 209 on the chain 208 of the dryer is indicated by the arrow F.

De façon générale, chaque barre de reprofilage 202 est fixée, par l'intermédiaire d'un support 214, sur une chaíne sans fin 211, entraínée en rotation par deux arbres 212 parallèles, par l'intermédiaire d'organes de transmission 248.Generally, each reshaping bar 202 is fixed, via a support 214, on a chain endless 211, driven in rotation by two shafts 212 parallel, via transmission devices 248.

Les arbres sont montés dans des paliers 213 fixés au bâti 201.The shafts are mounted in bearings 213 fixed to the built 201.

Les barres de reprofilage 202 sont parallèles aux arbres 212. Les supports 214 sont, dans l'exemple représenté, perpendiculaires à la chaíne 211 et mobiles en translation par rapport à cette dernière.The reprofiling bars 202 are parallel to the trees 212. The supports 214 are, in the example represented, perpendicular to the chain 211 and mobile in translation with respect to the latter.

De même, les barres de contre-forme sont fixées, par l'intermédiaire d'un support 215, sur une chaíne sans fin 216, entraínée en rotation par deux arbres 217 parallèles, par l'intermédiaire des organes de transmission 249. Similarly, the counter-form bars are fixed, by via a support 215, on an endless chain 216, driven in rotation by two parallel shafts 217, through the transmission members 249.

Les arbres 217 sont montés dans des paliers 218 fixés au bâti 201. Les barres de contre-forme 206 sont parallèles aux arbres 218. Les supports 215 sont, dans l'exemple représenté, perpendiculaires à la chaíne 216 et mobiles en translation par rapport à cette dernière.The shafts 217 are mounted in fixed bearings 218 to frame 201. The counter-bars 206 are parallel to the trees 218. The supports 215 are, in the example represented, perpendicular to the chain 216 and mobile in translation with respect to the latter.

Les barres de reprofilage et de contre-forme sont, par ailleurs, parallèles aux barres 207 du séchoir.The reprofiling and counterform bars are, for elsewhere, parallel to the bars 207 of the dryer.

Il faut souligner que le profil du matériau selon l'invention permet une bonne ventilation de la toiture, la vapeur d'eau pouvant facilement circuler.It should be noted that the profile of the material according to the invention allows good ventilation of the roof, the easily circulating water vapor.
