Abstract

The invention relates to a method making it possible to stiffen cardboard and to give it better mechanical resistance qualities. It consists in injecting, under pressure, rigid expanded foam m into ribs which are closed and connected to the surface of the cardboard; these ribs are cardboard shapes c which are folded, channelled, cut out or shaped otherwise and arranged in parallel, in a radiating pattern, intersecting or in another pattern according to the aesthetic or technical requirement. The finished assembly has the form of: - reinforced cardboard panels with one face plane and the other ribbed; - reinforced cardboard panels with two plane faces; - reinforced cardboard profiled sections with varied cross sections. The method according to the invention makes it possible to produce high-performance cardboards for use in many fields and, in particular, in decorating, furnishing and construction.

Description

La présente invention concerne un procédé qui permet de rigidifier le carton et de lui donner des qualités de résistance à la flexion, la compression, la traction et la torsion. The present invention relates to a method which makes it possible to stiffen the cardboard and to give it qualities of resistance to bending, compression, traction and torsion.

Les procédés connus de ce genre sont:
- d'une part, le carton ondulé, composé d'I ou de 2 feuilles de carton formant le revêtement extérieur et d'l feuille de carton roulée et ondulée en cannelures et contrecollée à ces dernières
- et d'autre part, un matériau composé de 2 feuilles de carton planes enserrant une âme en mousse rigide expansée d'épaisseur constante.The known processes of this kind are:
- on the one hand, corrugated cardboard, composed of I or 2 sheets of cardboard forming the outer covering and of a sheet of cardboard rolled and corrugated in grooves and laminated to the latter
- and on the other hand, a material composed of 2 sheets of flat cardboard enclosing a rigid expanded foam core of constant thickness.

Si ces procédés donnent au carton une plus grande rigidité et de meilleures performances mécaniques que d'ordinaire, ses qualités ne demeurent pas moins médiocres et font limiter son utilisation presque exclusivement au domaine de l'emballage et de la maquette. If these processes give the cardboard greater rigidity and better mechanical performance than usual, its qualities are not less mediocre and limit its use almost exclusively to the field of packaging and models.

Le procédé selon l'invention permet d'obtenir des cartons ayant de bien meilleurs rendements dans ces domaines, il consiste
- - à préformer du carton ondulé(ou pas)par pliage, cannelage, découpe ou autres techniques.The method according to the invention makes it possible to obtain cartons having much better yields in these fields, it consists
- - to preform corrugated cardboard (or not) by folding, fluting, cutting or other techniques.

- à le rapporter sur un autre carton ondulé(ou pas)afin de former à la surface de ce dernier un réseau de nervures fermées. - to bring it on another corrugated cardboard (or not) in order to form on the surface of the latter a network of closed ribs.

- à placer l'ensemble dans une presse moulante afin de prévenir d'éventuelles déformations. - place the assembly in a molding press in order to prevent possible deformation.

- et à y injecter de la mousse expansée rigide qui a la propriété de remplir ces cavités de façon complète et homogène et de coller solidement et définitivement ces cartons entre eux. - And to inject rigid foam which has the property of filling these cavities in a complete and homogeneous manner and of firmly and permanently bonding these cartons together.

Ces nervures dont le nombre, la section et la forme sont calculés en fonction des efforts demandés, peuvent être parallèles, rayonnantes ou croisées ou devenir de véritables surfaces en relief selon l'exigence esthétique ou technique. These ribs, the number, section and shape of which are calculated according to the forces required, may be parallel, radiating or crossed or become real relief surfaces according to the aesthetic or technical requirement.

Ce matériau nouveau, réalisé à partir du procédé selon ltinvention, est un carton armé dont la peau est en carton et l'armature un cadre rigide, résistant et léger de nervures en mousse expansée solidifiée qui tend à s'opposer à toutes déformations du carton. This new material, produced from the process according to the invention, is a reinforced cardboard, the skin of which is made of cardboard and the frame a rigid, resistant and light frame of ribs of expanded solidified foam which tends to oppose any deformation of the cardboard. .

Ce matériau nouveau, réalisé à partir du procédé selon l'invention, se présente sous forme de:
- panneau avec une face plane et l'autre nervurée.This new material, produced from the process according to the invention, is in the form of:
- panel with one flat side and the other ribbed.

- panneau avec les 2 faces planes, les nervures étant alors de simples bandes de carton de largeur constante placées de chant entre 2 feuilles de carton et qui forment des cavités dans lesquelles est injectée la mousse expansée rigide. - panel with the 2 flat faces, the ribs then being simple strips of cardboard of constant width placed on edge between 2 sheets of cardboard and which form cavities into which the rigid expanded foam is injected.

- et par extension et suivant le même procédé, tous profilés en carton ondulé ou non avec une âme pleine en mousse expansée rigide. - and by extension and following the same process, all profiles of corrugated cardboard or not with a solid core of rigid expanded foam.

Les dessins annexés sont des vues en axonométrie illustrant les différents aspects que peut prendre ce matériau selon le procédé de l'invention. The accompanying drawings are views in axonometry illustrating the different aspects that this material can take according to the method of the invention.

La figure 1 illustre le cas du panneau avec une face plane et l'autre nervurée. Figure 1 illustrates the case of the panel with a flat face and the other ribbed.

La figure 2 illustre le cas du panneau avec 2 faces planes. Figure 2 illustrates the case of the panel with 2 flat faces.

La figure 3 illustre le cas des profilés. Figure 3 illustrates the case of profiles.

La lettre de référence C figurant sur les dessins désigne le carton, la lettre de référence M désigne la mousse expansée rigide. The reference letter C appearing on the drawings designates the carton, the reference letter M designates the rigid expanded foam.

Ces dessins ne sont donnés qu à titre d'exemples et ne limitent en aucun cas les formes, les tailles et disposition des nervures ainsi que les formes des profilés. These drawings are given only as examples and in no way limit the shapes, sizes and arrangement of the ribs as well as the shapes of the profiles.

Le procédé, objet de l'invention, peut être utilisé dans tous les cas où l'on exige un matériau léger, plan, rigide et indéformable et dont les résistances mécaniques doivent être supérieures à celles du carton traité selo##grocédés existants, par exemple dans le domaine de la décoration, de l'ameublement et de la construction.  The process which is the subject of the invention can be used in all cases where a light, flat, rigid and non-deformable material is required and the mechanical strengths of which must be greater than that of the existing treated selo ## cardboard, by example in the field of decoration, furniture and construction.
