Abstract

To produce a mattress, this new method starts with a raw slab of latex (1), whose dimensions are non-standard for a mattress. The new approach places the slab in a rigid frame of set dimensions, which is essentially a forming templet (3), and which causes slab compression. Over the upper surface, a covering (4) of greater stiffness is e.g. adhered. This maintains the width and/or length of the slab after it is pulled out, at a value corresponding to that of the templet frame (3), resulting in a mattress of standard width and/or length. Also claimed is a bedding mattress made as described.

Description

La présente invention concerne un procédé de réalisation d'un matelas à partir d'une plaque brute de latex, ainsi qu'un matelas de literie obtenu par un tel procédé.The present invention relates to a method of making a mattress from a raw plate of latex, as well than a bedding mattress obtained by such a process.

Les normes actuellement en vigueur imposent une tolérance de ±1 cm sur les dimensions des matelas finis de literie comportant une plaque interne de latex.The standards currently in force impose a tolerance ± 1 cm on the dimensions of finished bedding mattresses with an internal latex plate.

Cependant, les producteurs de plaques de latex destinées à la réalisation de matelas de literie ne peuvent actuellement garantir qu'une tolérance de ± 2 cm sur les dimensions de la plaque brute de latex.However, producers of latex plates intended to the production of bedding mattresses cannot currently guarantee that a tolerance of ± 2 cm on the dimensions of the raw latex plate.

Pour satisfaire ces conditions des normes actuelles, les producteurs sont contraints de recouper les plaques de latex lorsque les dimensions réelles de ces plaques sont telles que les dimensions du matelas ne répondent plus aux normes. De plus, comme la mesure des dimensions d'une plaque de latex est relativement difficile à effectuer puisqu'elle dépend de la manière dont est posée la plaque, il y a un risque réel de redécouper des plaques de latex alors que cela n'était pas nécessaire. Enfin, l'opération de redécoupage de la plaque de latex s'effectue en bordure de celle-ci, ce qui diminue le renfort de matière et occasionne un risque important d'affaissement des bords de la plaque.To meet these conditions of current standards, the producers are forced to cut the plates of latex when the actual dimensions of these plates are such that the dimensions of the mattress no longer meet Standards. Furthermore, like measuring the dimensions of a latex plate is relatively difficult to perform since it depends on the way in which the plate, there is a real risk of re-cutting plates latex when it was not necessary. Finally, the re-cutting operation of the latex plate takes place at the edge of it, which reduces the reinforcement of material and poses a significant risk sagging edges of the plate.

La présente invention a pour but d'éliminer les inconvénients ci-dessus en proposant un procédé de réalisation d'un matelas à partir d'une plaque brute de latex pouvant avoir des dimensions telles que celles du matelas ne répondent pas aux normes habituelles et qui est caractérisé en ce qu'il consiste à placer la plaque brute de latex dans un cadre rigide formant gabarit de dimensions prédéterminées telles que le cadre comprime la plaque brute de latex ; à fixer au-dessus d'une face supérieure de la plaque brute de latex comprimée, par exemple par collage, un revêtement de rigidité élevée de façon à maintenir au moins la largeur ou la longueur de la plaque brute de latex, lorsque cette dernière est retirée du cadre formant gabarit, à une valeur sensiblement égale à celle de la largeur ou de la longueur prédéterminée du cadre formant gabarit pour obtenir une largeur ou une longueur de matelas normalisée.The object of the present invention is to eliminate the disadvantages above by proposing a method of production of a mattress from a raw plate of latex which may have dimensions such as those of mattresses do not meet the usual standards and which is characterized in that it consists in placing the plate raw latex in a rigid frame forming a template predetermined dimensions such that the frame compresses the raw latex plate; to be fixed above a face top of the raw compressed latex plate, by example by gluing, a coating of high rigidity of so as to maintain at least the width or length of the raw latex plate, when the latter is removed from the template frame, at a value substantially equal to that of the width or the predetermined length of the template frame for get a width or length of mattress standardized.

Selon un mode de réalisation, le procédé consiste à fixer le revêtement rigide précité directement sur la face supérieure de la plaque brute du latex comprimée ; à retourner la plaque brute de latex dans le cadre formant gabarit ; et à fixer directement sur la face inférieure de la plaque brute de latex, par exemple par collage, un autre revêtement de rigidité élevée, de façon à maintenir la largeur et la longueur de la plaque brute de latex, lorsque cette dernière est retirée du cadre formant gabarit, à des valeurs sensiblement égales respectivement aux valeurs de largeur et de longueur prédéterminées du cadre formant gabarit pour réaliser un matelas de dimensions normalisées.According to one embodiment, the method consists in fixing the aforementioned rigid coating directly on the face upper of the raw plate of compressed latex; at invert the raw latex plate in the forming frame template; and attach directly to the underside of the raw latex plate, for example by bonding, a other coating of high rigidity, so as to maintain the width and length of the raw latex plate, when the latter is removed from the frame forming gauge, at substantially equal values respectively at the predetermined width and length values of the frame forming a template for making a mattress standard dimensions.

Chaque revêtement rigide est collé sur toute la surface correspondante de la plaque brute de latex.Each rigid covering is glued over the entire surface corresponding to the raw latex plate.

Selon une variante, chaque revêtement rigide est collé sur la périphérie de la surface correspondante de la plaque brute de latex.According to a variant, each rigid covering is glued on the periphery of the corresponding surface of the raw latex plate.

Selon un autre mode de réalisation, le procédé consiste à encadrer la plaque brute de latex par des tronçons longitudinaux et transversaux, dont au moins les deux tronçons longitudinaux sont en un matériau plus rigide que le latex de la plaque brute ; à fixer, par exemple par collage, les deux tronçons longitudinaux aux bords longitudinaux correspondants de la plaque brute de latex et aux extrémités correspondantes des tronçons transversaux ; à placer l'ensemble ainsi formé dans le cadre formant gabarit ; à fixer le revêtement précité sous forme de bande transversale directement sur deux parois de faces supérieures correspondantes opposées respectivement des deux tronçons longitudinaux ; à retourner l'ensemble dans le cadre formant gabarit ; et à fixer, par exemple par collage, un autre revêtement de rigidité élevée sous forme de bande transversale directement sur deux portions de faces inférieures correspondantes opposées des deux tronçons longitudinaux de façon à maintenir la largeur et la longueur de la plaque brute de latex, lorsque cette dernière est retirée du cadre formant gabarit, à des valeurs sensiblement égales respectivement aux valeurs de largeur et de longueur prédéterminées du cadre formant gabarit pour réaliser un matelas de dimensions normalisées.According to another embodiment, the method consists in frame the raw latex plate with sections longitudinal and transverse, at least both of which longitudinal sections are made of a more rigid material than the latex of the raw plate; to fix, for example by gluing, the two longitudinal sections at the edges corresponding lengths of the raw latex plate and at the corresponding ends of the sections transverse; to place the assembly thus formed in the frame forming a template; to fix the aforementioned coating in the form of a transverse strip directly over two opposite corresponding upper face walls respectively of the two longitudinal sections; at return the assembly in the frame forming a template; and to attach, for example by gluing, another coating of high stiffness in the form of a transverse strip directly on two portions of lower faces opposite correspondents of the two longitudinal sections so as to maintain the width and length of the raw latex plate, when the latter is removed of the frame forming a template, at values substantially equal to the width and predetermined length of the template frame for make a mattress of standardized dimensions.

De préférence, les tronçons longitudinaux et transversaux sont en matériau mousse de polyéther haute densité.Preferably, the longitudinal and transverse sections are made of high density polyether foam material.

De préférence également, les revêtements rigides précités sont en un matériau intissé d'un gramage allant de 40 g/m2 à 100 g/m2 et d'un allongement inférieur ou égal à 2%.Preferably also, the abovementioned rigid coatings are made of a non-woven material with a weight ranging from 40 g / m 2 to 100 g / m 2 and an elongation less than or equal to 2%.

L'invention propose également un matelas de literie comprenant une plaque interne de latex et qui est caractérisé en ce qu'il comprend au moins un revêtement de rigidité élevée fixé au-dessus d'une face de la plaque interne de latex, par exemple par collage, de façon à maintenir au moins la largeur ou la longueur de la plaque de latex à une valeur normalisée de largeur ou de longueur du matelas. The invention also provides a bedding mattress comprising an internal latex plate and which is characterized in that it comprises at least one coating of high rigidity fixed above one face of the plate internal latex, for example by bonding, so that maintain at least the width or length of the plate latex to a standard width or length of the mattress.

Selon un mode de réalisation, le revêtement rigide précité est fixé directement sur la face correspondante de la plaque de latex et un autre revêtement de rigidité élevée est fixé directement, par exemple par collage, sur la face opposée de la plaque de latex, de façon à maintenir la largeur et la longueur de la plaque de latex à des valeurs de largeur et de longueur normalisées du matelas.According to one embodiment, the rigid coating above is fixed directly on the corresponding face latex plate and another stiffness coating high is fixed directly, for example by gluing, on the opposite side of the latex plate, so that maintain the width and length of the latex plate at normalized width and length values of mattress.

Selon un autre mode de réalisation, le matelas comprend des tronçons longitudinaux et transversaux d'encadrement de la plaque de latex, dont les tronçons longitudinaux sont fixés par collage aux bords longitudinaux correspondants de la plaque de latex et aux extrémités correspondantes des tronçons transversaux, les tronçons longitudinaux ayant une rigidité plus élevée que celle du latex, le revêtement rigide précité étant en forme de bande transversale fixée par collage directement sur deux portions de faces supérieures correspondantes opposées respectivement des deux tronçons longitudinaux et un autre revêtement en forme de bande transversale est fixé par collage directement sur deux portions de faces inférieures correspondantes opposées respectivement des deux tronçons longitudinaux de façon à maintenir la largeur et la longueur de la plaque de latex à des valeurs de largeur et de longueur normalisées du matelas.According to another embodiment, the mattress comprises longitudinal and transverse framing sections of the latex plate, the longitudinal sections of which are fixed by gluing to the longitudinal edges latex plate correspondents and ends corresponding cross sections, the sections longitudinal with higher rigidity than latex, the aforementioned rigid covering being in the form of transverse band fixed by gluing directly on two opposite corresponding upper face portions respectively of the two longitudinal sections and one other cross-shaped covering is attached by bonding directly on two portions of faces corresponding corresponding lower respectively two longitudinal sections so as to maintain the width and length of the latex plate at standard width and length values of the mattress.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaítront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant deux modes de réalisation de l'invention et dans lesquels :The invention will be better understood and other aims, features, details and benefits of it will appear more clearly during the description explanatory which will follow made with reference to the drawings attached diagrams given only by way of example illustrating two embodiments of the invention and wherein :

Les figures 1 et 2 représentent en coupe longitudinale deux plaques de latex respectivement alvéolée et perforée destinées chacune à la réalisation d'un matelas de literie.Figures 1 and 2 show in longitudinal section two latex sheets, respectively dimpled and perforated each intended for the production of a mattress bedding.

Les figures 3 et 4 représentent différentes étapes du procédé de l'invention permettant la réalisation d'un matelas de dimensions normalisées comprenant la plaque de latex de la figure 1.Figures 3 and 4 show different stages of the process of the invention allowing the production of a standard size mattress including the plate Figure 1 latex.

La figure 5 représente la plaque de latex de l'invention obtenue par le procédé des figures 3 et 4.FIG. 5 represents the latex plate of the invention obtained by the method of FIGS. 3 and 4.

La figure 6 est une vue semblable à celle de la figure 5 et représentant la plaque de latex de la figure 2 dont les dimensions précises sont obtenues par les étapes du procédé de l'invention pour satisfaire les dimensions normalisées du matelas comportant une telle plaque.Figure 6 is a view similar to that of Figure 5 and representing the latex plate of Figure 2 including the precise dimensions are obtained by the steps of method of the invention to satisfy the dimensions standard of the mattress comprising such a plate.

La figure 7 est une vue en perspective d'un autre mode de réalisation d'une plaque interne de matelas de dimensions précises obtenues par le procédé de l'invention pour réaliser un matelas de dimensions normalisées.Figure 7 is a perspective view of another mode of realization of an internal mattress plate of dimensions precise obtained by the process of the invention for make a mattress of standardized dimensions.

La figure 1 représente en coupe longitudinale une plaque de latex 1 du type à alvéoles 2 destinée à réaliser un matelas de dimensions normalisées peuvant être, par exemple, de 190 cm en longueur et de 140 cm en largeur. Figure 1 shows a longitudinal section of a plate of latex 1 of the cell type 2 intended to produce a standard size mattresses which can be, for example example, 190 cm in length and 140 cm in width.

Les normes actuellement en vigueur en France imposent une tolérance de ± 1 cm sur les dimensions en longueur et en largeur des matelas finis et comme des producteurs de plaques de latex 1 ne peuvent garantir que des tolérances de ± 2 cm sur les dimensions en longueur et largeur de chaque plaque brute de latex, il est nécessaire de résoudre un tel problème.The standards currently in force in France impose a tolerance of ± 1 cm on the dimensions in length and in width of the finished mattresses and as producers of latex plates 1 can only guarantee tolerances ± 2 cm on the length and width dimensions of each raw plate of latex, it is necessary to solve such a problem.

Selon l'invention, comme représenté en figure 3, la plaque de latex 1 est placée dans un cadre rigide formant gabarit 3 de dimensions prédéterminées telles que le cadre comprime la plaque brute de latex 1. A titre d'exemple, le cadre peut avoir des dimensions de 187 cm en longueur et de 137 cm en largeur pour réaliser un matelas de dimensions réelles normalisées de 188 cm de longueur et de 138 cm de largeur, les dimensions ci-dessus mentionnées du matelas, c'est-à-dire 190 cm de longueur et 140 cm de largeur, étant en fait les dimensions commerciales. Du fait que la plaque de latex 1 a été découpée aux dimensions de 190 cm x 140 cm avec une tolérance de ± 2 cm, la mise en place de la plaque 1 dans le cadre 3 comprime la plaque. Une fois la plaque 1 mise en place dans le cadre 3, un revêtement indéchirable 4, de préférence en matériau intissé à un gramage allant de 40 g/m2 et 100 g/m2, est fixé par collage sur la plaque brute de latex comprimée 1. Comme représenté schématiquement, le revêtement 4 de rigidité supérieure à celle du latex, est fixé par collage sur la périphérie de la face supérieure de la plaque 1, mais bien entendu ce revêtement peut être collé sur toute la surface supérieure de celle-ci. Ensuite, l'ensemble de la plaque de latex 1 et du revêtement rigide 4 est retourné dans le cadre formant gabarit 3 et un autre revêtement 5 de rigidité élevée identique à celle du revêtement, de préférence en un matériau intissé de gramage allant de 40 g/m2 à 100 g/m2, est fixé par collage sur la face inférieure de la plaque de latex 1. Comme pour le revêtement 4, le revêtement 5 est fixé sur la périphérie de la face inférieure de la plaque de latex 2 mais il peut être également fixé sur toute la face inférieure de celle-ci.According to the invention, as shown in FIG. 3, the latex plate 1 is placed in a rigid frame forming a template 3 of predetermined dimensions such that the frame compresses the raw latex plate 1. By way of example, the frame may have dimensions of 187 cm in length and 137 cm in width to make a mattress of real standard dimensions of 188 cm in length and 138 cm in width, the dimensions mentioned above of the mattress, that is to say 190 cm in length and 140 cm in width, being in fact the commercial dimensions. Because the latex plate 1 has been cut to the dimensions of 190 cm x 140 cm with a tolerance of ± 2 cm, the positioning of the plate 1 in the frame 3 compresses the plate. Once the plate 1 has been placed in the frame 3, a tear-resistant coating 4, preferably of non-woven material with a grammage ranging from 40 g / m 2 and 100 g / m 2 , is fixed by bonding to the raw latex plate compressed 1. As shown diagrammatically, the coating 4 of rigidity greater than that of the latex, is fixed by gluing on the periphery of the upper face of the plate 1, but of course this coating can be glued on the entire upper surface of this- this. Then, the assembly of the latex plate 1 and of the rigid coating 4 is turned inside the frame forming a template 3 and another coating 5 of high rigidity identical to that of the coating, preferably in a non-woven material of grammage ranging from 40 g. / m 2 to 100 g / m 2 , is fixed by gluing to the underside of the latex plate 1. As for the covering 4, the covering 5 is fixed to the periphery of the underside of the latex plate 2 but it can also be fixed on the entire underside thereof.

Une fois la plaque de latex 1 retirée du cadre 3, elle conserve pratiquement les mêmes dimensions que celles de ce cadre du fait que les deux revêtements 4, 5 ont une rigidité très élevée, c'est-à-dire des propriétés d'allongement en directions longitudinale et transversale extrêmement faibles, par exemple inférieures à 2%. Ainsi, la plaque de latex 1, grâce aux revêtements rigides 4 et 5 présente des dimensions de 187 cm x 137 cm pour des tolérances de ± 0,5 cm, ce qui permet de respecter les tolérances de réalisation des matelas selon les normes françaises actuellement en vigueur et établies à ±1 cm. La plaque de latex 1 ainsi réalisée permet de maítriser parfaitement et rapidement la réalisation et la finition du matelas. De plus, le procédé de fabrication de la plaque de latex 1 munie de ses revêtements rigides 4, 5, permet d'éviter des retours au service après-vente du matelas à plaque de latex ayant des côtes trop courtes et d'éviter également le retour de matelas au service après-vente à cause d'un affaissement des bords du matelas dus à une plaque de latex redécoupée.Once the latex plate 1 removed from the frame 3, it retains practically the same dimensions as those of this part of the fact that the two coatings 4, 5 have a very high rigidity, i.e. properties elongation in longitudinal and transverse directions extremely low, for example less than 2%. So, the latex plate 1, thanks to the rigid coatings 4 and 5 has dimensions of 187 cm x 137 cm for tolerances of ± 0.5 cm, which allows compliance with tolerances for making mattresses according to standards currently in force and established at ± 1 cm. The latex plate 1 thus produced makes it possible to control perfectly and quickly the realization and the finish of the mattress. In addition, the manufacturing process of the latex plate 1 provided with its rigid coatings 4, 5, avoids returns to the after-sales service latex plate mattress with too short ribs and also to avoid the return of mattresses to after-sales service due to sagging edges of the mattress due to a re-cut latex plate.

La figure 6 montre la réalisation d'une plaque de latex du type perforée telle que celle représentée en figure 2 réalisée dans les mêmes conditions que la plaque de latex 1 de la figure 1 pour fixer par l'intermédiaire du cadre formant gabarit 3 des revêtements de rigidité élevée 4, 5 afin de maintenir la longueur et la largeur de la plaque à des valeurs permettant la réalisation du matelas répondant aux normes actuelles. Figure 6 shows the realization of a latex plate of the perforated type such as that shown in FIG. 2 produced under the same conditions as the latex plate 1 of Figure 1 for fixing via the frame forming a template 3 of the high rigidity coatings 4, 5 to maintain the length and width of the plate to values allowing the realization of the mattress meeting current standards.

La figure 7 représente une variante de réalisation d'une plaque brute de latex 1 par exemple du type perforée et agencée de façon à réaliser des matelas de dimensions normalisées.FIG. 7 represents an alternative embodiment of a raw latex plate 1 for example of the perforated type and arranged to produce mattresses of dimensions standardized.

Cette variante de réalisation permet également de réduire les dimensions des plaques de latex en vue de diminuer les couts de latex, qui est une matière très chère.This alternative embodiment also makes it possible to reduce the dimensions of the latex plates in order to reduce the cost of latex, which is a very expensive material.

Comme représenté en figure 7, la plaque de latex 1 comporte des tronçons longitudinaux 6 et transversaux 7 encadrant la plaque 1 et dont au moins les deux tronçons longitudinaux 6 sont en un matériau plus rigide que le latex de la plaque brute 1. De préférence, les tronçons longitudinaux 6, comme les tronçons transversaux 7, sont réalisés en un matériau mousse de polyéther haute densité de gramage par exemple de 28 g/m2. Les tronçons rigides longitudinaux 6 sont fixés par collage respectivement sur les deux bords longitudinaux de la plaque de latex 1 et les deux tronçons transversaux 7, dont un seul est représenté en figure 7, sont fixés par collage, au niveau de leurs extrémités, entre les deux parties correspondantes de tronçons longitudinaux 6 en saillie de la plaque 1.As shown in FIG. 7, the latex plate 1 has longitudinal 6 and transverse 7 sections framing the plate 1 and of which at least the two longitudinal sections 6 are made of a more rigid material than the latex of the raw plate 1. Preferably, the longitudinal sections 6, like the transverse sections 7, are made of a high density polyether foam material, for example 28 g / m 2 . The longitudinal rigid sections 6 are fixed by gluing respectively to the two longitudinal edges of the latex plate 1 and the two transverse sections 7, only one of which is shown in FIG. 7, are fixed by gluing, at their ends, between the two corresponding parts of longitudinal sections 6 projecting from the plate 1.

Un revêtement 8 de rigidité plus élevée que le latex et indéchirable, de préférence en un matériau intissé ayant un gramage de 40 g/m2 à 100 g/m2, est réalisé en forme de bande transversale et fixé par collage directement sur deux portions de faces supérieures correspondantes opposées respectivement des deux tronçons longitudinaux 6. Un autre revêtement identique en forme de bande (non représenté) est également fixé par collage à la face opposée de la plaque de latex 1 directement sur deux portions de faces inférieures correspondantes opposées respectivement des deux tronçons longitudinaux 6. Chacun des deux revêtements rigides peut avoir une largueur d'environ 500 mm.A coating 8 of higher rigidity than latex and tear-resistant, preferably in a non-woven material having a weight of 40 g / m 2 to 100 g / m 2 , is produced in the form of a transverse strip and fixed by bonding directly on two portions of corresponding upper faces opposite respectively of the two longitudinal sections 6. Another identical coating in the form of a strip (not shown) is also fixed by gluing to the opposite face of the latex plate 1 directly on two portions of corresponding lower faces opposite respectively of the two longitudinal sections 6. Each of the two rigid coverings may have a width of approximately 500 mm.

Ainsi, les deux bandes de revêtement rigides assurent le maintien de la largeur de la plaque de latex à une valeur permettant de satisfaire la valeur de largeur normalisée d'un matelas, tandis que les deux tronçons longitudinaux rigides 6 permettent de maintenir la longueur de la plaque de latex 1 à une valeur permettant de réaliser un matelas de longueur normalisée.Thus, the two rigid covering strips ensure the keeping the width of the latex plate at a value to satisfy the standard width value of a mattress, while the two longitudinal sections rigid 6 maintain the length of the latex plate 1 at a value allowing a standard length mattress.

Ce mode de réalisation est avantageux puisqu'en prévoyant un encadrement à tronçons longitudinaux et transversaux de la plaque 1, cette dernière peut avoir des dimensions réduites, par exemple d'une longueur L de 180 cm et d'une largeur 1 de 120 cm au lieu de 190 cm et de 140 cm, soit une réduction de matière de latex de 18,8%, pour une largeur 11 d'un tronçon longitudinal 6 de 10cm et une largeur 12 de tronçon transversal 7 de 5 cm. De plus, la zone centrale de la plaque de latex habituellement renforcés par du latex plus dense pour affermir le matelas peut être assurée grâce à l'effet de renfort des deux revêtements 8 en bandes d'intissé collées sur les deux tronçons longitudinaux 6, ce qui diminue d'environ 3 à 4% la matière latex utilisée habituellement dans la zone centrale de la plaque 1, soit un gain total de latex supérieur à 20%.This embodiment is advantageous since by providing a frame with longitudinal and transverse sections of plate 1, the latter may have dimensions reduced, for example by a length L of 180 cm and a width 1 of 120 cm instead of 190 cm and 140 cm, i.e. a reduction in latex material of 18.8%, for a width 11 of a longitudinal section 6 of 10cm and a width 12 of transverse section 7 of 5 cm. In addition, the central area of the latex plate usually reinforced with denser latex to firm the mattress can be ensured thanks to the reinforcing effect of two coverings 8 in non-woven strips bonded to the two longitudinal sections 6, which decreases by about 3 at 4% the latex material usually used in the central area of plate 1, for a total gain in latex greater than 20%.

Bien entendu, la plaque 1 et ses tronçons longitudinaux 6 et transversaux 7 représentés en figure 7 est réalisée dans un cadre formant gabarit du genre représenté aux figures 3 et 4 pour permettre d'amener cet ensemble à des dimensions permettant la réalisation d'un matelas aux dimensions normalisées. Ainsi, la plaque 1 munie de ses tronçons longitudinaux 6 et transversaux 7 est placée dans le cadre formant gabarit dont les dimensions déterminées permettent de comprimer cet ensemble à des valeurs telles que lorsque l'ensemble est retiré du cadre formant gabarit, les dimensions de cet ensemble sont sensiblement égales à celles du cadre pour réaliser le matelas aux dimensions normalisées. Pendant que l'ensemble est comprimé dans le cadre, une bande transversale de revêtement intissé 8 est fixée par collage sur deux parties correspondantes des tronçons longitudinaux 6 en venant en contact sur la face supérieure de la plaque 1. Ensuite, l'ensemble est retourné dans le cadre pour coller l'autre revêtement en forme de bande en matériau intissé sur les deux parties correspondantes des tronçons longitudinaux 6.Of course, the plate 1 and its longitudinal sections 6 and transverse 7 shown in Figure 7 is made in a frame forming a template of the kind shown in Figures 3 and 4 to allow this set to be brought to dimensions allowing the realization of a mattress with standard dimensions. Thus, the plate 1 provided with its longitudinal 6 and transverse 7 sections are placed in the frame forming a template whose dimensions determined allow to compress this set to values such as when the assembly is removed from the frame forming a template, the dimensions of this set are substantially equal to those of the framework to achieve the mattress with standardized dimensions. While the assembly is compressed in the frame, a strip transverse non-woven covering 8 is fixed by bonding on two corresponding parts of the sections longitudinal 6 coming into contact on the face top of plate 1. Then the assembly is returned to the frame to glue the other coating in strip form of non-woven material on both sides corresponding to the longitudinal sections 6.

Ainsi, la géométrie parallélépipédique des dimensions précises de l'ensemble est respectée grâce à l'encadrement constitué des tronçons 6, 7 de rigidité plus élevée que celle du latex et grâce aux deux bandes transversales de matériau intissé collées sur les deux tronçons rigides longitudinaux 6 de façon à maintenir la longueur et la largueur de cet ensemble à des valeurs précises de faibles tolérances (± 0,5 cm) permettant la réalisation de matelas aux dimensions normalisées.So the parallelepiped geometry of the dimensions of the whole is respected thanks to the frame consisting of sections 6, 7 of rigidity higher than that of latex and thanks to the two bands non-woven material glued on both rigid longitudinal sections 6 so as to maintain the length and width of this set at values precise low tolerances (± 0.5 cm) allowing the production of mattresses with standardized dimensions.

De plus, les tronçons 6, 7, de résistance mécanique plus élevée que celle du latex, renforcent efficacement les bords du matelas.In addition, the sections 6, 7, of greater mechanical strength higher than that of latex, effectively reinforce edges of the mattress.
