L'invention s'applique notamment au conditionnement de rouleaux en matériaux isolants fibreux.The invention relates to a burden of at least two layers of rollers of compressible material. In this burden, the rollers of each layer are placed side by side and in contact with each other, while the rollers of two superimposed layers are in mutual contact by their lower or upper generatrix. The burden further comprises two profiled plates adjoining the end layers of rollers, and two tying pieces bearing on the profiled plates and oriented orthogonally to one another. The invention is particularly applicable to the packaging of rolls of fibrous insulating materials.

Description

La présente-invention concerne un procédé et un dispositif pour réaliser des fardeaux de matériaux compressibles, notamment de matériaux isolants fibreux, qui se présentent eux-mêmes sous forme de rouleaux.The present invention relates to a method and a device for making burdens of compressible materials, in particular of fibrous insulating materials, which are themselves in the form of rolls.

On connaît différents emballages ou conditionnement de matériaux enroulés qui s'appliquent, soit à des rouleaux individuels, soit à des rouleaux rassemblés bout à bout. L'emballage est, dans ces différents cas, constitué généralement par une ou plusieurs feuilles de papier rabattues sur les extrémités du rouleau ou de l'assemblage, ou bien par des feuilles de matière plastique du genre feuille de polyéthylène, éventuellement rétractées par traitement thermique. Ces divers types d'emballage unitaires ne sont plus susceptibles de répondre d'une manière satisfaisante aux besoins des utilisateurs dans le domaine de la construction, car de très grandes quantités de produits sont manipulées depuis les lieux de production jusqu'à ceux de l'utilisation.Various wrappers or wrapping of rolled materials are known which apply either to individual rolls or to rolls assembled end to end. The packaging is, in these different cases, generally constituted by one or more sheets of paper folded over the ends of the roll or of the assembly, or else by sheets of plastic material of the polyethylene sheet type, possibly shrunk by heat treatment. . These various types of unit packaging are no longer capable of satisfying satisfactorily the needs of users in the construction field, because very large quantities of products are handled from the places of production to those of the use.

Dans le cas des matériaux légers, tels que les matériaux isolants, le volume couvert nécessaire au stockage de tels matériaux peut atteindre un tiers du volume de stockage total des matériaux de construction manipulés par les utilisateurs. Jusqu'à présent, la technique de la palettisation a permis de résoudre les problèmes posés par la manutention des matériaux lourds, tels que briques, ciments, etc..., mais l'emploi de palettes consignées, de même que celui de conteneurs consignés, impose une procédure de récupération de ce matériel, avec des risques de détérioration impliquant un partage de responsabilité, Cette solution n'a pas été retenue jusqu'ici pour les matériaux légers.In the case of light materials, such as insulating materials, the covered volume necessary for the storage of such materials can reach one third of the total storage volume of the construction materials handled by the users. Until now, the palletizing technique has solved the problems posed by the handling of heavy materials, such as bricks, cements, etc., but the use of returnable pallets, as well as that of returnable containers , imposes a procedure for recovering this material, with risks of deterioration implying a sharing of responsibility. This solution has not been retained so far for light materials.

En ce qui concerne les rouleaux de matériaux légers, il a été envisagé de regrouper plusieurs dizaines de rouleaux unitaires, tels que les rouleaux isolants individuels cités plus haut, de façon à constituer un fardeau, par exemple cubique, pouvant dépasser le volume de 15 m3 et un poids de plusieurs centaines de kilos. Mais ce volume et ce poids rendent difficile la manipulation de tels fardeaux, à moins d'employer des moyens de manutention spécifiques et coûteux, tant sur les lieux de production que dans les entrepôts de stockage et sur les lieux d'utilisation. C'est ainsi que des moyens de manutention construits à cet usage, tels que camions-grues ou chariots élévateurs, sont indispensables pour effectuer de telles manutentions ce qui conduit généralement à des investissements coûteux. En outre, ces fardeaux ont des dimensions telles qu'ils. ne peuvent pas être stockés dans les entrepôts courants, très souvent équipés de casiers, de râteliers ou de greniers de dimensions insuffisantes.With regard to the rolls of light materials, it has been envisaged to group together several tens of unitary rolls, such as the insulating rolls individuals mentioned above, so as to constitute a burden, for example cubic, which can exceed the volume of 15 m 3 and a weight of several hundred kilos. However, this volume and this weight make it difficult to handle such burdens, unless specific and expensive handling means are used, both on the production sites, in the storage warehouses and at the places of use. This is how handling means built for this purpose, such as crane trucks or forklifts, are essential for carrying out such handling, which generally leads to costly investments. In addition, these burdens have dimensions such as they do. cannot be stored in common warehouses, very often equipped with lockers, racks or attics of insufficient size.

De tels fardeaux volumineux pourraient être également stockés à l'air libre, mais alors ils devraient être étanches et résister à toutes les intempéries (gel, pluie et ensoleillement), ce qui augmenterait prohibiti- vement leur prix.Such bulky burdens could also be stored in the open air, but then they should be waterproof and withstand all weather conditions (frost, rain and sunshine), which would prohibitively increase their price.

Il a été envisagé'également de produire des fardeaux dans lesquels des produits isolants élastiques sont rassemblés sous forme comprimée. Des fardeaux de ce type sont connus, dans lesquels des panneaux isolants fibreux comprimés sont empilés les uns sur les autres (brevet français 2 216 811). D'autres fardeaux de ce type contiennent des produits fibreux tubulaires, tels que coquilles isolantes, empilées à l'état aplati les unes sur les autres (brevet U.S. 3 587 201). De tels modes de production de fardeaux ne sont pas réalisables à partir des matériaux isolants considérés, du fait que ceux-ci ne peuvent être réduits à un tel état de compression sans inconvénients.It has also been envisaged to produce bundles in which elastic insulating products are collected in compressed form. Burdens of this type are known, in which compressed fibrous insulating panels are stacked one on top of the other (French patent 2,216,811). Other burdens of this type contain tubular fibrous products, such as insulating shells, stacked in a flattened state on top of each other (U.S. Patent 3,587,201). Such methods of producing burdens cannot be made from the insulating materials considered, since these cannot be reduced to such a state of compression without drawbacks.

L'invention vise à remédier à ces inconvénients en proposant un nouveau type de fardeau de rouleaux d'une matière compressible, notamment de rouleaux d'isolants, dans lequel la matière compressible n'est soumise qu'à une compression limitée, en vue d'éviter sa déformation permanente, qui se prête à une manutention par des dispositifs usuels tels que des chariots à fourche et qui peut être gerbé pour le stockage.The invention aims to remedy these drawbacks by proposing a new type of roll burden of a compressible material, in particular of insulation rolls, in which the compressible material is only subjected to a limited compression, in order to avoid its permanent deformation, which lends itself to handling by conventional devices such as forklifts and which can be stacked for storage.

A cet effet, l'invention a pour objet un fardeau d'au moins deux couches de rouleaux d'un matériau compressible, les rouleaux de chaque couche étant placés côte à côte et au contact les uns des autres, tandis que les rouleaux de deux couches superposées sont en contact mutuel par leur génératrice inférieure ou supérieure, ce fardeau étant caractérisé en ce qu'il comporte :*

  • -- deux plaques profilées attenant aux couches extrêmes de rouleaux, et
  • - deux liages prenant appui sur les plaques profilées et orientées orthogonalement l'un par rapport à l'autre.
To this end, the invention relates to a burden of at least two layers of rollers of compressible material, the rollers of each layer being placed side by side and in contact with each other, while the rollers of two superimposed layers are in mutual contact by their lower or upper generatrix, this burden being characterized in that it comprises: *
  • - two profiled plates adjoining the extreme layers of rollers, and
  • - two bindings bearing on the profiled plates and oriented orthogonally to each other.

De préférence, une housse de papier ou de matière plastique étirable ou rétractable enveloppera les rouleaux, les plaques et les liages, pour protéger l'ensemble des intempéries et améliorer le frettage du fardeau.Preferably, a cover of stretchy or shrinkable paper or plastic will wrap the rolls, the plates and the tying, to protect all the weather and improve the shrinking of the burden.

Avantageusement, lesdites plaques profilées seront réunies par des panneaux transversaux pour former l'un desdits liages, tandis que des rubans ou feuillards en plastique constitueront le second liage, perpendiculairement au précédent.Advantageously, said profiled plates will be joined by transverse panels to form one of said tying, while ribbons or plastic strips will constitute the second tying, perpendicular to the previous one.

Selon une caractéristique importante de l'invention les plaques profilées attenant à deux faces opposées du fardeau comporteront chacune deux passages pour la fourche d'un dispositif de manutention, ces passages résultant du pliage ou du moulage du matériau constitutif de ces plaques. Bien entendu, les panneaux transversaux comporteront dans ce cas des perforations pour le passage de ladite fourche, ou des aires repérées déterminées que perforera ladite fourche lors de la manutention du fardeau.According to an important characteristic of the invention, the profiled plates adjoining two opposite faces of the load will each have two passages for the fork of a handling device, these passages resulting from the folding or molding of the material constituting these plates. Of course, the panels transver saux will in this case have perforations for the passage of said fork, or determined marked areas that perforate said fork during the handling of the burden.

L'invention a également pour objet un procédé de réalisation d'un tel fardeau, caractérisé en ce que :

  • - on dispose sur une plaque profilée une première couche de rouleaux placés côte à côte et au contact les uns des autres ;
  • ≈ on empile sur cette première couche au moins une autre couche constituée comme la première couche, les rouleaux de la seconde couche étant en contact par leur génératrice inférieure avec la génératrice supérieure des rouleaux de la première couche ;
  • - on pose une plaque profilée sur l'empilement et l'on comprime celui-ci entre les deux plaques profilées ; et
  • on lie l'empilement maintenu à l'état comprimé avec des liens prenant appui sur lesdites plaques et constituant deux liages orientés orthogonalement l'un par rapport à l'autre.
The subject of the invention is also a method for producing such a burden, characterized in that:
  • - a first layer of rollers placed side by side and in contact with each other are placed on a profiled plate;
  • ≈ at least one other layer constituted as the first layer is stacked on this first layer, the rollers of the second layer being in contact by their lower generatrix with the upper generatrix of the rollers of the first layer;
  • - A profiled plate is placed on the stack and it is compressed between the two profiled plates; and
  • the stack kept in the compressed state is linked with links bearing on said plates and constituting two links oriented orthogonally to one another.

De préférence, on enveloppe ensuite l'assemblage ainsi réalisé avec une housse en papier ou en une matière plastique étirable ou rétractable.Preferably, the assembly thus produced is then wrapped with a paper cover or a stretchable or shrinkable plastic material.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, ce dispositif étant caractérisé en ce qu'il comporte :

  • - une assise pour la plaque profilée inférieure et l'empilement des couches de rouleaux ;
  • - un plateau supérieur, mobile par rapport à ladite assise sous la sollicitation de moyens de compression ; et
  • - des butoirs latéraux constituant un gabarit de fardeau.
The invention also relates to a device for implementing this method, this device being characterized in that it comprises:
  • - a seat for the lower profiled plate and the stacking of the layers of rollers;
  • - An upper plate, movable relative to said seat under the stress of compression means; and
  • - side buffers constituting a burden gauge.

Ladite assise comportera de préférence des supports individuels pour les rouleaux de la première couche, lesdits supports individuels étant réglables en position les uns par rapport aux autres, en vue de s'adapter à des rouleaux de dimensions différentes. Ces supports auront de préférence un profil épousant la forme des rouleaux.Said seat will preferably include individual supports for the rolls of the first layer, said individual supports being adjustable in position relative to each other, in order to adapt to rolls of different dimensions. These supports will preferably have a profile matching the shape of the rollers.

Les butoirs latéraux constituant un gabarit seront eux aussi de préférence réglables en position l'un par rapport à l'autre. Avantageusement, ces butoirs comporteront des ouvertures pour le passage de feuillards ou d'organes similaires de liage.The side buffers constituting a template will also preferably be adjustable in position relative to each other. Advantageously, these buffers will have openings for the passage of strips or similar tying members.

Enfin, un dernier objet de l'invention est constitué par l'application desdits fardeaux au stockage de rouleaux d'un matériau compressible, par gerbage desdits fardeaux en piles de pluralités de fardeaux.Finally, a final object of the invention consists of the application of said burdens to the storage of rolls of compressible material, by stacking of said burdens in stacks of pluralities of burdens.

Les dessins annexés illustrent la mise en oeuvre de l'invention. Sur ces dessins :

  • la figure 2 est une vue en perspective de ce même fardeau ;
  • la figure 3 illustre le gerbage d'une pluralité de fardeaux de six rouleaux et de neuf rouleaux ;
  • les figures 4 et 5 sont deux vues en élévation, l'une .de face et l'autre latérale, d'un dispositif pour la mise en oeuvre de l'invention.
The accompanying drawings illustrate the implementation of the invention. In these drawings:
  • Figure 1 is an exploded perspective view of a burden of six rollers;
  • Figure 2 is a perspective view of the same burden;
  • Figure 3 illustrates the stacking of a plurality of bundles of six rolls and nine rolls;
  • Figures 4 and 5 are two elevational views, one facing and the other side, of a device for the implementation of the invention.

Le fardeau conforme à l'invention représenté sur les figures 1 et 2 est constitué de six rouleaux 1 d'une matière compressible, par exemple d'un isolant thermique fibreux. Ces rouleaux sont regroupés en deux couches superposées de trois rouleaux, les rouleaux d'une même couche étant disposés en parallèle et en contact mutuel, tandis que les rouleaux de la couche supérieure reposent par leur génératrice inférieure sur la génératrice supérieure des rouleaux de la première couche.The burden according to the invention shown in Figures 1 and 2 consists of six rollers 1 of a compressible material, for example a fibrous thermal insulator. These rollers are grouped into two superimposed layers of three rollers, the rollers of the same layer being arranged in parallel and in mutual contact, while the rollers of the upper layer rest by their lower generatrix on the upper generatrix of the rollers of the first layer.

Les rouleaux de la couche inférieure sont supportés par une plaque 2.en matière plastique moulée ou en carton, qui a été profilé pour épouser la forme des rouleaux 1 et pour ménager des passages triangulaires 3 pour une fourche d'un dispositif de manutention.The rollers of the lower layer are supported by a molded plastic plate. or cardboard, which has been shaped to match the shape of the rollers 1 and to provide triangular passages 3 for a fork of a handling device.

De façon analogue, une plaque 2 identique coiffe les rouleaux de la couche supérieure.Similarly, an identical plate 2 covers the rollers of the upper layer.

Des panneaux 4, également en matière plastique ou en carton, sont disposés contre les extrémités des rouleaux 1 et sont rendus solidaires des plaques 2 par des rabats 5 contrecollés contre ces plaques. Les plaques 2 et les panneaux 4 forment ainsi un premier liage enserrant les rouleaux 1. Les panneaux 4 comportent des découpes 6 en regard des passages 3 des plaques profi~ lées 2.Panels 4, also made of plastic or cardboard, are arranged against the ends of the rollers 1 and are made integral with the plates 2 by flaps 5 laminated against these plates. The plates 2 and the panels 4 thus form a first binding enclosing the rollers 1. The panels 4 have cutouts 6 facing the passages 3 of the profi ~ lated plates 2.

Un second liage, orthogonal au précédent, est constitué par deux feuillards 7 de matière plastique, de polypropylène par exemple, qui enserrent les rouleaux 1 perpendiculairement à leur axe.A second bond, orthogonal to the previous one, consists of two strips 7 of plastic, polypropylene for example, which grip the rollers 1 perpendicular to their axis.

Enfin, une housse 8 en un matériau rétractable, par exemple du polyéthylène d'une épaisseur comprise entre 0,07 mm et 0,15 mm, enveloppe l'ensemble constitué par les rouleaux 1, les plaques profilées 2, les panneaux 4 et les feuillards 7.Finally, a cover 8 made of a retractable material, for example polyethylene with a thickness of between 0.07 mm and 0.15 mm, envelops the assembly formed by the rollers 1, the profiled plates 2, the panels 4 and the straps 7.

Le liage constitué par les plaques 2 et les panneaux 4 maintient le lot de rouleaux 1 et évite qu'il ne se déforme latéralement, tandis que le cerclage à l'aide des feuillards 7 prévient le glissement longitudinal des rouleaux. La housse 8 en matériau rétractable protège le fardeau contre les intempéries.The binding formed by the plates 2 and the panels 4 holds the batch of rollers 1 and prevents it from deforming laterally, while the strapping using strips 7 prevents the longitudinal sliding of the rollers. The cover 8 made of retractable material protects the burden from the weather.

Pour la manutention d'un tel fardeau à l'aide d'un chariot élévateur à fourche, il suffira de percer la housse 8 au moyen de la fourche et d'engager les dents de celle-ci dans les découpes 6 des panneaux 4 et les passages 3 des plaques 2. Il est ainsi possible de gerber facilement plusieurs fardeaux, identiques ou non, les uns sur les autres, comme on le voit sur la figure 3. On peut réaliser des fardeaux de six ou neuf rouleaux, ou même davantage. A titre d'exemple, la figure 3 montre une pile de fardeaux de six et neuf rouleaux.For the handling of such a burden using a forklift, it will suffice to pierce the cover 8 by means of the fork and to engage the teeth thereof in the cutouts 6 of the panels 4 and the passages 3 of the plates 2. It is thus possible to stack several burdens, identical or not, on top of each other, as seen in FIG. 3. Burdens of six or nine can be produced rolls, or even more. For example, Figure 3 shows a stack of burdens of six and nine rolls.

La Demanderesse a ainsi réalisé des fardeaux de rouleaux d'isolant thermique fibreux, présentant les caractéristiques suivantes :

  • Fardeaux de six rouleaux :
    • - diamètre des rouleaux : 500 à 550 millimètres,
    • - longueur du fardeau : 1 600 mm,
    • - largeur : (longueur des rouleaux) : 1 200 mm,
    • - hauteur du fardeau : 860 mm,
    • - poids du fardeau : environ 95 kg,
The Applicant has thus produced bundles of rolls of fibrous thermal insulation, having the following characteristics:
  • Loads of six rolls:
    • - roller diameter: 500 to 550 millimeters,
    • - length of the burden: 1600 mm,
    • - width: (roll length): 1,200 mm,
    • - burden height: 860 mm,
    • - burden weight: about 95 kg,

On peut gerber trois fardeaux de ce type, soit au total 18 rouleaux.We can stack three loads of this type, a total of 18 rolls.

Fardeaux de neuf rouleaux :

  • - diamètre des rouleaux : 500 à 550 millimètres,
  • - longueur du fardeau :.l 600 mm
  • - largeur : (longueur des rouleaux) : 1 200 mm,
  • - hauteur du fardeau : 1 280 mm
  • - poids du fardeau : 145 kg environ.
Loads of nine rolls:
  • - roller diameter: 500 to 550 millimeters,
  • - length of the load: .l 600 mm
  • - width: (roll length): 1,200 mm,
  • - burden height: 1280 mm
  • - burden weight: around 145 kg.

On peut gerber deux fardeaux de ce type, soit 18 rouleaux, comme dans le cas précédent.We can stack two loads of this type, 18 rolls, as in the previous case.

Dans la pratique, pour réduire le volume du fardeau et pour accroître sa résistance mécanique, les rouleaux 1 sont comprimés sous une pression inférieure à la pression que provoquerait leur déformation permanente, avant d'être assemblés par les liages orthogonaux.In practice, to reduce the volume of the burden and to increase its mechanical strength, the rollers 1 are compressed under a pressure lower than the pressure which their permanent deformation would cause, before being assembled by orthogonal tying.

Dans le cas des rouleaux d'isolant thermique dont les caractéristiques viennent d'être données, on comprime en général ces rouleaux de manière à provoquer une réduction de 10 à 25 % de leur diamètre, ce qui correspond à une pression de 1 000 à 2 200 Pa. A titre d'exemple, une pression de 1 550 Pa (correspondant à un effort de 250 kg) provoque une réduction de diamètre de 17 %.In the case of rolls of thermal insulation, the characteristics of which have just been given, these rolls are generally compressed so as to cause a reduction of 10 to 25% in their diameter, which corresponds to a pressure of 1000 to 2 200 Pa. For example, a pressure of 1,550 Pa (corresponding to an effort of 250 kg) causes a reduction in diameter of 17%.

Pour réaliser les fardeaux conformes à l'invention et pour comprimer les lots de rouleaux, on utilisera avantageusement le dispositif représenté schématiquement sur les figures 4 et 5.To make the burdens according to the invention and to compress the batches of rollers, the device shown diagrammatically in FIGS. 4 and 5 will advantageously be used.

Ce dispositif comprend une base 10, munie de supports 11 réglables en position, des parois latérales constituées par des plaques verticales 12 ou éventuellement des plaques 12' représentées en traits interrompus figure 5 séparées par des intervalles 13, et un plateau supérieur 14, parallèle à la base 10 et pouvant se déplacer par rapport à celle-ci sur un bâti 15 sous l'effet d'un vérin 16. Le plateau 14 est muni de blocs d'appui 17.This device comprises a base 10, provided with supports 11 adjustable in position, side walls formed by vertical plates 12 or possibly plates 12 ′ shown in broken lines in FIG. 5 separated by intervals 13, and an upper plate 14, parallel to the base 10 and which can move relative to the latter on a frame 15 under the effect of a jack 16. The plate 14 is provided with support blocks 17.

Une plaque 2 préalablement profilée reposant sur les supports 11, dont la position a été réglée pour que chacun d'entre eux soit à l'aplomb d'un rouleau 1, on empile les différentes couches de rouleaux et l'on coiffe la dernière avec une plaque 2 identique à la précédente. A l'aide du plateau 14 et du vérin 15, on comprime alors légèrement le lot de rouleaux jusqu'au volume désiré et l'on maintient le plateau 14 dans cette position.A previously profiled plate 2 resting on the supports 11, the position of which has been adjusted so that each of them is in line with a roller 1, the different layers of rollers are stacked and the last is capped with a plate 2 identical to the previous one. Using the plate 14 and the cylinder 15, the batch of rollers is then slightly compressed to the desired volume and the plate 14 is maintained in this position.

Il est alors possible de cercler les rouleaux au moyen des feuillards 7 en faisant passer ces feuillards dans les intervalles 13 qui séparent les plaques 12..On colle enfin les rabats 5 des panneaux 4 sur les extrémités des plaques inférieure et supérieure 2. On peut aussi procéder à ce collage avant d'effectuer le cerclage des rouleaux.It is then possible to encircle the rollers by means of the strips 7 by passing these strips in the intervals 13 which separate the plates 12. Finally, the flaps 5 of the panels 4 are glued to the ends of the lower and upper plates 2. It is possible to also do this bonding before strapping the rollers.

On retire alors le lot de rouleaux du'dispositif de compression et on l'enveloppe d'une housse 8 en polyéthylène rétractable, avant de faire passer l'ensemble dans un four de rétraction.The batch of rolls of the compression device is then removed and it is wrapped in a cover 8 of shrinkable polyethylene, before passing the assembly through a shrink oven.

Du fait de la compression des rouleaux, préalablement à leur assemblage, les plaques profilées 2 et les panneaux 4 travaillent en traction, lorsqu'on supprime la pression exercée lors de la constitution du fardeau, en même temps qu'un effet de raidissement est exercé par les panneaux 4 sur l'empilement. Cette précompres- sion rend aussi les plaques 2 et les panneaux 4 particulièrement aptes à travailler en compression, lorsque les fardeaux sont gerbés et qu'ils supportent le poids d'autres fardeaux.Due to the compression of the rollers, prior to their assembly, the profiled plates 2 and the panels 4 work in traction, when the pressure exerted during the constitution of the load is removed, at the same time as a stiffening effect is exerted by the panels 4 on the stack. This precompression also makes the plates 2 and the panels 4 particularly suitable for working in compression, when the loads are stacked and that they support the weight of other loads.

Naturellement, on pourrait substituer aux panneaux 4 tout autre moyen connu dans la technique et apte à remplir les mêmes fonctions.Naturally, the panels 4 could be replaced by any other means known in the art and capable of fulfilling the same functions.

L'invention propose donc un procédé particulièrement simple pour la constitution de fardeaux de rouleaux d'une matière compressible, notamment de rouleaux d'isolant thermique, qui favorise la manutention et le stockage de ces fardeaux sans qu'il soit nécessaire de recourir à des palettes et à de grandes surfaces de stockage.The invention therefore provides a particularly simple method for forming bundles of rollers of a compressible material, in particular rolls of thermal insulation, which promotes the handling and storage of these burdens without the need to resort to pallets and large storage areas.

On notera qu'il est facile, pour l'utilisateur, d'extraire les rouleaux des fardeaux qui viennent d'être décrits et que les matériaux constitutifs de ces fardeaux sont peu volumineux, peu coûteux et facilement destructibles après utilisation.It will be noted that it is easy for the user to extract the rollers from the bundles which have just been described and that the materials constituting these bundles are not very bulky, inexpensive and easily destructible after use.

Le procédé conforme à l'invention est transposable à des articles de matière compressible ne se présentant pas sous la forme de rouleaux, par exemple à des blocs sensiblement parallélépipédiques de mousse de matière plastique, ou encore à des paquets de matériaux thermiquement isolants, à condition que la forme de ces articles permette d'utiliser des plaques externes profilées, comportant des passages pour les dents d'une fourche d'un dispositif de manutention.The process according to the invention can be transposed to articles of compressible material which are not in the form of rolls, for example to substantially parallelepipedal blocks of plastic foam, or to bundles of thermally insulating materials, provided that the shape of these articles allows the use of profiled external plates, comprising passages for the teeth of a fork of a handling device.

Une telle application de ce procédé entre dans le cadre de la présente invention.Such an application of this method is within the scope of the present invention.
