Abstract
Description
L'invention concerne un élément de voiture autoportant préforme, et notamment un plafond de voiture, qui présente une structure de carton ondulé avec au moins une couche de carton ondulé et des couches de recouvrement, des bords de la structure de carton ondulé étant comprimés afin de réduire l'épaisseur du matériau. The invention relates to a preformed self-supporting car element, and in particular a car ceiling, which has a corrugated cardboard structure with at least one layer of corrugated cardboard and covering layers, edges of the corrugated cardboard structure being compressed so as to to reduce the thickness of the material.
On connait, pour l'habillage du côté intérieur de toits de voiture, des éléments profilés autoportants, appelés plafonds préfabriqués, qui comportent, en tant qu'élément porteur, une plaque de carton dur ondulée ou nervurée. Ces éléments peuvent être fabriqués à un prix avantageux, ils possèdent une bonne stabilité de forme grace à la structure de carton ondulé et ils sont néanmoins légers. Afin de raidir encore le plafond préfabriqué, il est en outre connu de renforcer principalement sa région médiane par une plaque supplémentaire. A cet effet, il est nécessaire de découper une autre plaque et de la poser dans la position correcte - après avoir appliqué au préalable une couche de colle. We know, for the covering of the interior side of car roofs, self-supporting profiled elements, called prefabricated ceilings, which comprise, as a supporting element, a corrugated or ribbed hard cardboard plate. These elements can be manufactured at an advantageous price, they have good shape stability thanks to the corrugated cardboard structure and they are nevertheless light. In order to further stiffen the prefabricated ceiling, it is also known to mainly reinforce its middle region with an additional plate. For this purpose, it is necessary to cut another plate and place it in the correct position - after having previously applied a layer of glue.
On connait, d'après la demande de brevet allemand nO 27 04 529, un élément de voiture autoportant, qui présente une couche de carton ondulé et des couches de recouvrement et dont le bord circonférentiel est comprimé lors du façonnage, de telle manière que l'élément fini présente, dans la région de son bord, une épaisseur plus petite qu'au milieu. Or il existe, dans la région du bord, qui présente les déformations les plus marquées, le risque de formation de plis et de fissures. A cet égard, ce sont les côtés ot la structure de carton ondulé est déformée dans la direction de l'ondulation qui posent le plus de problèmes. We know, from German patent application No. 27 04 529, a self-supporting car element, which has a layer of corrugated cardboard and covering layers and whose circumferential edge is compressed during shaping, so that the 'finite element has, in the region of its edge, a thickness smaller than in the middle. However there is, in the region of the edge, which presents the most marked deformations, the risk of formation of folds and cracks. In this respect, it is the sides where the corrugated cardboard structure is deformed in the direction of the corrugation which pose the most problems.
L'invention a pour but de perfectionner un élément de voiture du genre en question, de telle manière qu'il puisse être fabriqué économiquement avec une meilleure qualité. The invention aims to improve a car element of the kind in question, so that it can be manufactured economically with better quality.
Ce but est atteint par le fait qu'au niveau de deux cotés mutuellement opposés, la ou les couches de carton ondulé ne s'étendent pas jusqu'aux bords et forment des gradins paral lèles entre eux. This object is achieved by the fact that at two mutually opposite sides, the layer or layers of corrugated cardboard do not extend to the edges and form parallel steps between them.
Grace à la forme en gradin sur deux côtés opposés, on parvient à ce que le demi-produit pour l1élément de voiture peut être constitué par une pièce découpée dans une bande de carton ondulé fabriquée en continu. C'est-a-dire que lorsque la région médiane doit être renforcée, il n'y a pas, comme dans des modes de réalisation connus, a découper plusieurs plaques, a les réunir-et à les coller. Thanks to the stepped shape on two opposite sides, it is achieved that the semi-finished product for the car element can consist of a piece cut from a strip of corrugated cardboard produced continuously. That is to say that when the middle region must be reinforced, there is no need, as in known embodiments, to cut several plates, to join them together and to glue them.
Par rapport à un élément de voiture fabriqué dans un dispositif suivant la demande de brevet allemand nO 27 04 529, il existe le grand avantage qu'il n'y a pas a comprimer quatre, mais seulement deux bords et que, pour ce faire, on peut choisir les bords qui sont plus facilement déformables sans formation de plis (bords parallèles aux ondulations de la structure de papier ondulé). Compared to a car element manufactured in a device according to German patent application No. 27 04 529, there is the great advantage that there is not to compress four, but only two edges and that, to do this, you can choose the edges that are more easily deformable without the formation of folds (edges parallel to the corrugations of the corrugated paper structure).
I1 est particulièrement avantageux que les bords parallèles aux gradins soient formés d'au moins deux couches de recouvrement. La région du bord s'en trouve renforcée et, malgré cella, la possibilité de déformation n'est pas amoindrie. En comparaison d'une structure de carton ondulé comprimé , la région du bord n'est guère plus épaisse, pour une résistance à près égale, ce qui fait que cette région peut être insérée dans une bande de garniture, par exemple par serrage en position rabattue. It is particularly advantageous for the edges parallel to the steps to be formed from at least two covering layers. The edge region is reinforced and, despite this, the possibility of deformation is not diminished. Compared to a structure of compressed corrugated cardboard, the edge region is not much thicker, for almost equal resistance, which means that this region can be inserted in a strip of filling, for example by clamping in position folded down.
Selon les données de construction et l'aspect extérieur voulu, il peut être également opportun de renforcer les régions bordantes de l'élément de voiture par application d'une couche supplémentaire. De ce fait, les régions bordantes sont dotées d'une rigidité suffisante et elles peuvent constituer en même temps un pare-soleil, si l'on utilise pour le renfort un matériau approprié et si celui-ci est place du côté dirigé vers l'espace intérieur. Depending on the construction data and the desired exterior appearance, it may also be advisable to reinforce the bordering regions of the car element by applying an additional layer. Therefore, the bordering regions are provided with sufficient rigidity and they can constitute at the same time a sun visor, if one uses for the reinforcement an appropriate material and if this one is placed on the side directed towards the interior space.
I1 est particulièrement avantageux que la couche de recouvrement supérieure soit faite d'un matériau clivable dans l'épaisseur (par exemple un papier deux couches). De la sorte, l'élément de voiture peut être collé et néanmoins détaché ultérieurëment sans difficulté. Le collage d'éléments fabriqués en carton ondulé est déjà effectué a la construction de la voiture, lors de la fixation d'un plafond sur le toit du véhicule. Pour détacher le plafond préfabriqué en cas de réparration, on chauffe la région du toit a une température d'environ 140 à 1600C, ce qui fait que la colle réactivable se ramollit et que le plafond préfabriqué peut être détaché. Mais cette méthode prend beaucoup de temps et n'est pas réalisable sans moyens auxiliaires (soufflante d'air chaud ; chambre à réchauffer).Si l'on utilise, conformément a l'invention, un papier clivable ou un matériau clivable analogue comme couche de recouvrement supérieure, le plafond préfabriqué qui est collé au toit de la voiture peut être détaché sans moyens auxiliaires. Dans ces conditions, il reste, sur le toit de la voiture, une couche du matériau qui constitue le support pour l'encollage, au moment où le plafond préfabriqué est remonté. It is particularly advantageous that the upper covering layer is made of a material which can be cleaved through the thickness (for example a two-layer paper). In this way, the car element can be glued and nevertheless detached later without difficulty. The bonding of elements made of corrugated cardboard is already carried out at the construction of the car, when fixing a ceiling on the roof of the vehicle. To detach the prefabricated ceiling in the event of repair, the area of the roof is heated to a temperature of about 140 to 1600C, which means that the reactivable glue softens and that the prefabricated ceiling can be detached. However, this method is very time-consuming and cannot be carried out without auxiliary means (blower of hot air; chamber to be heated). If, in accordance with the invention, a cleavable paper or a similar cleavable material is used as a layer overlap, the prefabricated ceiling which is glued to the roof of the car can be detached without auxiliary means. Under these conditions, there remains, on the roof of the car, a layer of the material which constitutes the support for the gluing, when the prefabricated ceiling is raised.
Pour la fabrication de l'élément de voiture suivant l'invention, l'utilisation d'une structure de carton ondulé, avec les combinaisons les plus diverses de couches de carton ondulé et de couches de recouvrement, est possible. Les couches de carton ondulé et les couches de recouvrement qui forment la structure de carton ondulé peuvent être réunies de façon continue en un demi-produit qui peut avoir 2000 a 3000 m de longueur. For the manufacture of the car element according to the invention, the use of a corrugated cardboard structure, with the most diverse combinations of layers of corrugated cardboard and covering layers, is possible. The layers of corrugated cardboard and the cover layers which form the structure of corrugated cardboard can be continuously joined into a semi-finished product which can be 2000 to 3000 m in length.
La longueur nécessaire peut être alors découpée dans ce demiproduit et transformée (formée), sans qu'il soit par exemple nécessaire d'appliquer au préalable une seconde couche de carton ondulé en une opération séparée.The necessary length can then be cut from this semi-product and transformed (formed), without it being for example necessary to apply beforehand a second layer of corrugated cardboard in a separate operation.
Les différentes couches de la structure de carton ondulé sont opportunément unies entre elles au moyen de colles réactivables, ce qui fait qu'un déplacement des couches lors du formage de l'élément de voiture est possible. The different layers of the corrugated cardboard structure are suitably joined together by means of reactivable adhesives, which makes it possible to move the layers during the forming of the car element.
Les éléments de voiture suivant l'invention peuvent constituer par exemple des habillages de paroi ou de porte, un couvercle de coffre ou un plafond préfabriqué. La fabrication d'un plafond préfabriqué est illustrée à titre d'exemple par les dessins et est décrite ci-après de façon plus détaillée. The car elements according to the invention can constitute, for example, wall or door coverings, a trunk lid or a prefabricated ceiling. The manufacture of a prefabricated ceiling is illustrated by way of example by the drawings and is described below in more detail.
La figure 1 est une représentation schématique d'un dispositif de production pour la fabrication d'un demiproduit pour un plafond préfabriqué. Figure 1 is a schematic representation of a production device for the manufacture of a semi-product for a prefabricated ceiling.
La figue 2 montre la structure du demi-produit fabriqué dans le dispositif de production représenté sur la figure 1. Fig 2 shows the structure of the semi-finished product produced in the production device shown in Figure 1.
La figure 3 est une vue en coupe, suivant la ligne
III-III, du demi-produit de la figure 2, après qu'il a été mis sous la forme d'un plafond préfabriqué.Figure 3 is a sectional view along the line
III-III, of the semi-finished product of FIG. 2, after it has been put in the form of a prefabricated ceiling.
La figure 4 est une vue en coupe, suivant la ligne IV-IVdu demi-produit, également après qu'il a été mis sous la forme d'un plafond préfabriqué. Figure 4 is a sectional view along line IV-IV of the semi-finished product, also after it has been put into the form of a prefabricated ceiling.
D'après la figure 1, un dispositif pour la fabrication d'un demi-produit 5 pour un plafond préfabriqué comporte un tambour 7 garni de carton ondulé, pour la formation d'une couche de carton ondulé 9. Au moment où la couche de carton ondulé 9 déroulée atteint un dispositif 11, les sommets de ses ondulations sont enduits de colle sur les deux côtés, pu-is il est appliqué, sur chacune de ses deux faces, une bande de papier, ces bandes constituant des couches de recouvrement 17 et 19 pour la couche de carton ondulé 9. Les deux couches de recouvrement 17 et 19 sont pressées contre la couche de carton ondulé 9 par deux cylindres rotatifs 21 et 23. According to Figure 1, a device for manufacturing a semi-finished product 5 for a prefabricated ceiling comprises a drum 7 lined with corrugated cardboard, for the formation of a layer of corrugated cardboard 9. When the layer of corrugated cardboard 9 unwound reaches a device 11, the tops of its corrugations are coated with glue on both sides, then there is applied, on each of its two faces, a strip of paper, these strips constituting covering layers 17 and 19 for the layer of corrugated cardboard 9. The two covering layers 17 and 19 are pressed against the layer of corrugated cardboard 9 by two rotary cylinders 21 and 23.
Au moyen d'un tambour 25 garni de carton ondulé, une seconde couche de carton ondulé 27 est appliquée sur la couche de recouvrement 17, après que la couche de carton ondulé 27 a traversé un dispositif 29 qui enduit de colle les sommets des ondulations sur les deux cotés de la couche de carton ondule 27. Puis une bande de papier clivable à deux couches est appli quée à partir d'un tambour 33 sur la couche de carton ondulé 27 en tant que couche de recouvrement supérieure 31 et elle est pressée par deux cylindres 35 et 37 en rotation. Ainsi, le demi-produit 5 est achevé sous sa forme définitive. By means of a drum 25 lined with corrugated cardboard, a second layer of corrugated cardboard 27 is applied to the covering layer 17, after the layer of corrugated cardboard 27 has passed through a device 29 which coats the tops of the corrugations on the two sides of the corrugated cardboard layer 27. Then a strip of two-layer cleavable paper is applied from a drum 33 to the corrugated cardboard layer 27 as an upper covering layer 31 and is pressed by two cylinders 35 and 37 in rotation. Thus, the semi-finished product 5 is completed in its final form.
Aux cylindres 35 et 37 fait suite un dispositif de découpage 39 qui coupe les longueurs nécessaires pour la fabrication de plafonds préfabriqués. The cylinders 35 and 37 are followed by a cutting device 39 which cuts the lengths necessary for the manufacture of prefabricated ceilings.
La figure 2 montre, en une vue en perpective, les largeurs choisies pour les couches de papier ondulé et les couches de recouvrement. FIG. 2 shows, in a perspective view, the widths chosen for the layers of corrugated paper and the covering layers.
Au découpage fait suite le formage. Celui-ci peut etre effectué dans des dispositifs connus et, pour cette raison, on ne les a pas représentés en détail. La figure 3 est une vue en coupe de l'élément de construction formé, qui constitue maintenant un plafond préfabriqué, cette vue en coupe étant faite perpendiculairement a la direction de fabrication du demiproduit. La figure 4 est une vue en coupe du toit préfabriqué, faite parallèlement à la direction de fabrication du demiproduit 5. Afin de faciliter la fixation du plafond préfabriqué et réduire sa hauteur a l'étant monté, sa région bordante 41 est comprimée lors du formage. Cutting is followed by forming. This can be done in known devices and, for this reason, they have not been shown in detail. Figure 3 is a sectional view of the formed building element, which now constitutes a prefabricated ceiling, this sectional view being made perpendicular to the direction of manufacture of the semi-product. Figure 4 is a sectional view of the prefabricated roof, made parallel to the direction of manufacture of the semi-finished product 5. In order to facilitate the fixing of the prefabricated ceiling and reduce its height when it is mounted, its bordering region 41 is compressed during forming .
