Abstract
Description
L'invention concerne un profilé en U pliable et plus particulièrement un profilé en carton, son procédé de fabrication et une installation pour la mise en oeuvre du procédé.The invention relates to a foldable U-profile and more particularly to a profile cardboard, its manufacturing process and an installation for the implementation of the process.
Il est connu d'utiliser les profilés en U notamment pour l'emballage.It is known to use U-shaped profiles in particular for packaging.
Le brevet Européen 0 411 045 décrit par exemple un conteneur d'emballage pour emballer des articles longs et qui comporte deux profilés en U emboítés l'un dans l'autre.European patent 0 411 045 describes for example a packaging container to pack long articles and which has two U-shaped profiles fitted one in the other.
Pour fabriquer de tels profilés, il est en particulier connu de contrecoller des bandes de papier ou carton et éventuellement de les recouvrir d'une enveloppe constituée d'une matière résistante du type carton par exemple.To manufacture such profiles, it is in particular known to laminate strips of paper or cardboard and possibly cover them with a constituted envelope a resistant material of the cardboard type for example.
De même, il est également connu de contrecoller à la flamme des bandes de complexes carton-polyoléfines pour obtenir divers profilés et notamment en U.Likewise, it is also known to flame-tape strips of cardboard-polyolefin complexes to obtain various profiles, in particular U-shaped.
Parmi les méthodes de fabrication de tels profilés en U à partir de bandes de matières résistantes, la seule méthode connue consiste à contrecoller les bandes les unes aux autres à plat, puis par une succession de postes de profilage et de formage, à effectuer deux plis principaux sur le produit en bande plane, à exécuter l'opération de pliage progressivement de façon à obtenir en final un profilé dont la coupe transversale est en forme de U.Among the methods of manufacturing such U-profiles from strips of resistant materials, the only known method is to laminate the strips to each other flat, then by a succession of profiling and forming stations, to make two main folds on the product in flat band, to execute the operation gradually folding so as to finally obtain a profile whose cross section is U-shaped.
Lors de la mise en oeuvre de cette technique, les couches contrecollées sont rapidement liées les unes aux autres par des liaisons puissantes provenant, soit de l'action de la colle utilisée dans le cas de bandes de carton, soit de l'action collante du polyéthylène réchauffé à la flamme dans le cas de bandes de complexes carton-polyéthylène.During the implementation of this technique, the laminated layers are quickly linked to each other by powerful bonds coming either from the action of the glue used in the case of cardboard strips, or the sticky action of the flame-heated polyethylene in the case of strips of cardboard-polyethylene complexes.
Le profilé en U ainsi obtenu par cette technique est rigide et l'angle formé entre le fond du U et chacune de ses deux ailes latérales est généralement voisin de 90° et n'est pas modifiable dès la prise de l'agent collant. Après fabrication, une modification importante de cet angle et un écartement des ailes dans une direction perpendiculaire à l'axe longitudinal du profilé, entraíne une détérioration dudit profilé en forme de U, par délamination des bandes le constituant, et en conséquence, l'impossibilité de l'utiliser.The U-profile thus obtained by this technique is rigid and the angle formed between the bottom of the U and each of its two side wings is generally close to 90 ° and cannot be changed as soon as the tackifier is taken. After manufacture, a modification significant of this angle and a spacing of the wings in a perpendicular direction to the longitudinal axis of the profile, causes a deterioration of said U-shaped profile, by delamination of the bands constituting it, and consequently, the impossibility of use it.
Les profilés en U obtenus par cette technique sont difficilement empilables contrairement, par exemple, aux profilés en L. La seule technique connue pour les empiler de manière à minimiser l'encombrement consiste à disposer les profilés en U tête-bêche deux à deux, c'est-à-dire que chaque profilé chevauche l'une des ailes d'un autre profilé.The U-profiles obtained by this technique are difficult to stack unlike, for example, L-shaped profiles. The only known technique for stacking in order to minimize the space requirement consists of arranging the U-shaped profiles head to tail two by two, i.e. each section overlaps one of the wings of a other profile.
On comprend aisément que les profilés rigides fabriqués selon ces procédés connus sont particulièrement onéreux à transporter et/ou à entreposer généralement après mise sur palettes, étant donné le volume considérable des empilements obtenus par rapport à la matière proprement dite.It is easy to understand that the rigid profiles manufactured according to these processes known are particularly expensive to transport and / or store generally after placing on pallets, given the considerable volume of stacks obtained compared to the material itself.
Le coût de transport unitaire est d'autant plus important que les profilés présentent de grandes dimensions.The unit transport cost is all the more important as the profiles have large dimensions.
La présente invention a notamment pour but de pallier cet inconvénient et d'optimiser l'empilement des profilés, en supprimant ou réduisant au mieux les volumes morts quelles que soient les dimensions des profilésThe object of the present invention is in particular to overcome this drawback and to optimize the stacking of profiles, by eliminating or reducing as much as possible the volumes dead regardless of the dimensions of the profiles
Pour optimiser ainsi les empilements, l'invention propose un profilé en U comportant un fond et deux ailes latérales, qui est notamment remarquable en ce qu'il est pourvu dans son fond d'une ligne longitudinale de pliage, en particulier situé sensiblement au voisinage de la ligne médiane dudit fond, de manière que ce dernier puisse se plier vers l'intérieur en même temps que les ailes s'évasent, de telle sorte que le profilé peut prendre à volonté une forme sensiblement de W, facilitant ainsi son empilement notamment pour son stockage et/ou son transport.To thus optimize the stacks, the invention proposes a U-shaped profile. comprising a bottom and two side wings, which is particularly remarkable in that it is provided at its bottom with a longitudinal fold line, in particular located substantially in the vicinity of the center line of the said bottom, so that the latter can fold inwards at the same time as the wings flare, so that that the profile can take a substantially W shape at will, thus facilitating its stacking in particular for its storage and / or transport.
L'invention propose aussi un procédé de fabrication d'un tel profilé en U, qui est remarquable en ce qu'il consiste à prévoir au cours de la fabrication du profilé, une étape de formation d'une ligne longitudinale de pliage dans le fond dudit profilé.The invention also provides a method of manufacturing such a U-shaped profile, which is remarkable in that it consists in providing during the manufacture of the profile, a step of forming a longitudinal fold line in the bottom of said profile.
Avantageusement, la ligne de pliage est réalisée sur un produit semi-fini plan, avant de réaliser les ailes du profilé par pliage.Advantageously, the folding line is produced on a flat semi-finished product, before making the wings of the profile by folding.
Pour la fabrication d'un profilé à partir de bandes de matières contrecollées, notamment en carton ou en complexe carton-polyoléfines, l'invention propose de réaliser la ligne de pliage par une opération de rainurage.For the manufacture of a profile from strips of laminated material, in particular in cardboard or in cardboard-polyolefin complex, the invention proposes to produce the fold line by a grooving operation.
Cette opération de rainurage peut être effectuée, par exemple, par enfoncement sans enlèvement de matière, ou par fraisage avec enlèvement de matière, ou encore par incision sur la face interne du fond.This grooving operation can be carried out, for example, by driving in without removal of material, or by milling with removal of material, or again by incision on the internal face of the bottom.
Selon un mode de réalisation, la ligne de pliage est renforcée sur au moins l'une des faces du fond du profilé par une bande de renfort rapportée.According to one embodiment, the fold line is reinforced on at least one of the faces of the bottom of the profile by an added reinforcing strip.
Dans ce dernier cas et avec un rainurage par incision, l'invention propose de disposer la bande de renfort au-dessus de l'incision en ménageant à cet endroit un repli pour permettre le pliage du profilé. In the latter case and with incision grooving, the invention proposes place the reinforcement strip over the incision, leaving a folded down to allow the profile to be folded.
Selon encore un mode de réalisation, on enveloppe avec la bande de renfort une grande partie du profilé à l'exception d'au moins une partie de l'une des faces du fond dudit profilé à l'endroit de la ligne de pliage de ce dernier.According to another embodiment, it is wrapped with the reinforcing strip a large part of the profile with the exception of at least part of one of the faces of the bottom of said section at the fold line of the latter.
L'invention propose encore un autre procédé qui est remarquable en ce qu'il consiste à raccorder deux profilés en L raboutés l'un à l'autre par l'une de leurs ailes au moyen d'une bande de jonction fixée sur lesdites ailes.The invention proposes yet another method which is remarkable in that it consists of connecting two L-shaped profiles which are joined together by one of their wings by means of a connecting strip fixed on said wings.
Enfin, l'invention propose également une installation pour la mise en oeuvre du procédé qui est remarquable en ce qu'elle comporte, outre les postes connus de confection d'un profilé en U, un poste de rainurage aménagé pour réaliser une rainure longitudinale sur la partie du profilé devant constituer le fond dudit profilé en U.Finally, the invention also proposes an installation for the implementation of the process which is remarkable in that it comprises, in addition to the known stations of production of a U-shaped profile, a grooving station designed to make a groove longitudinal on the part of the profile to constitute the bottom of said U-shaped profile.
L'invention sera bien comprise à la suite de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels:
- la figure 1 représente schématiquement en coupe un empilement de profilés en U classiques,
- la figure 2 représente schématiquement en coupe un empilement de profilés selon l'invention,
- les figures 3, 4 et 5 représentent un profilé selon l'invention pourvu d'une ligne de pliage obtenue selon trois modes de réalisation,
- les figures 6, 7 et 8 représentent des postes pour des installations de fabrication de profilés selon l'invention, notamment pour réaliser des profilés selon les figures respectivement 3, 4 et 5.
- les figures 9 à 19 représentent en vue d'extrémité divers types de profilés selon l'invention, en position d'utilisation (lettre a) et en position d'empilement (lettre b), c'est-à-dire en forme de W,
- la figure 20 montre une des étapes de fabrication du profilé de la figure 16.

- FIG. 20 shows one of the steps for manufacturing the profile of FIG. 16.
La figure 1 montre schématiquement un empilement de plusieurs profilés en U classiques. Figure 1 schematically shows a stack of several profiles in U classics.
Les profilés sont associés ici par paire avec une disposition tête-bêche par chevauchement.The profiles are associated here in pairs with a head-to-tail arrangement by overlap.
On peut ainsi aisément constater l'énorme perte de place au stockage et/ou pendant le transport de tels profilés classiques.We can easily see the enormous loss of space in storage and / or during the transport of such conventional profiles.
Au contraire, la figure 2 montre un empilement de profilés selon l'invention et on peut voir comment de tels profilés permettent un empilement optimisé en assurant un gain très important de place.On the contrary, FIG. 2 shows a stack of profiles according to the invention and we can see how such profiles allow optimized stacking by ensuring a very significant gain in space.
Les figures suivantes vont permettre de décrire les particularités et la manière de fabriquer des profilés selon l'invention.The following figures will describe the features and the way to manufacture profiles according to the invention.
Les figures 3, 4 et 5 montrent trois modes de réalisation selon l'invention.Figures 3, 4 and 5 show three embodiments according to the invention.
Les profilés 1 représentés sur lesdites figures 3, 4 et 5 sont en forme de U et
sont constitués d'un fond 1a et de deux ailes latérales 1b et 1c.The
Comme le montrent bien les figures 3 à 5, le fond 1a présente au voisinage
de sa ligne médiane et sur toute sa longueur une ligne de pliage 2, 2', 2" destinée à se
comporter comme une charnière. Toutefois, il est clair que ladite ligne de pliage pourrait
être décalée par rapport à ladite ligne médiane.As FIGS. 3 to 5 clearly show, the
Chaque ligne de pliage représentée 2, 2', 2" se présente sur les figures 3, 4
et 5 sous la forme d'une rainure (mot à considérer dans son sens le plus large), la
rainure 2 de la figure 3 étant réalisée par enfoncement de la matière avec son côté
concave sur la face interne du fond 1a du profilé, la rainure 2' étant réalisée par enlèvement
de matière sur la face externe du fond 1a du profilé et la rainure 2" étant réalisée
par incision effectuée sur la face interne du fond 1a du profilé.Each fold line shown 2, 2 ', 2 "is shown in Figures 3, 4
and 5 in the form of a groove (word to be considered in its broadest sense), the
Les profilés sont fabriqués en partie de manière connue, par exemple à partir de bandes ou feuilles résistantes, notamment en carton ou sous forme d'un complexe carton-polyoléfines, qui sont contrecollées entre elles.The profiles are partly produced in a known manner, for example from strong strips or sheets, especially of cardboard or in the form of a complex cardboard-polyolefins, which are laminated together.
Généralement, on réalise la ligne de pliage selon l'invention en cours de fabrication lorsque le produit se trouve encore sous forme plane, c'est-à-dire avant la réalisation des ailes par pliage.Generally, the folding line according to the invention is produced during manufacture when the product is still in flat form, i.e. before the wings made by folding.
Pour réaliser les lignes de pliage selon les figures 3 à 5, on pourra utiliser des
postes de confection du type de ceux représentés sur les figures 6, 7 et 8, lesquelles
figures montrent l'usinage d'un produit semi-fini 3 en bande pris entre deux moyens
rotatifs respectivement 4, 5; 6, 7; 8, 9.To make the fold lines according to Figures 3 to 5, we can use
garment stations of the type shown in FIGS. 6, 7 and 8, which
figures show the machining of a
Les moyens 4, 5 de la figure 6 se présentent sous forme de rouleaux ou cylindres
qui comportent respectivement une saillie circonférentielle 4' pour l'un et une
gorge correspondante 5' pour l'autre de manière à permettre un enfoncement de la
matière afin d'obtenir un profilé selon la figue 3.The
Si les moyens 7 et 9 des figures 7 et 8 sont des rouleaux ou cylindres lisses,
le moyen 6 est un système de fraisage, c'est-à-dire avec enlèvement de matière, et le
moyen 8 un rouleau muni d'un couteau circulaire 8' destiné à faire une incision dans
l'épaisseur de la matière, les postes représentés sur les figures 7 et 8 étant destinés à
réaliser des profilés selon les figures respectivement 4 et 5.If the
Les postes de façonnage représentés sur les figures 6, 7 et 8 sont aménagés entre deux postes classiques de fabrication de profilés en U, tels que les postes de collage et de pressage des bandes, les postes pour mettre en forme (pliage des ailes), les éventuels postes pour envelopper, les postes de tronçonnage, etc.The shaping stations shown in Figures 6, 7 and 8 are arranged between two conventional U-shaped profile manufacturing stations, such as gluing and pressing strips, stations for shaping (folding the wings), any positions for wrapping, cut-off positions, etc.
Ainsi, l'invention concerne non seulement les profilés en U pourvus d'une ligne
de pliage 2, 2', 2" ménagée sur le fond 1a du profilé, mais donc aussi le procédé
de fabrication et les moyens pour sa mise en oeuvre.Thus, the invention relates not only to U-shaped profiles provided with a
On comprend aisément que les profilés ainsi obtenus peuvent prendre une
position de stockage et/ou de transport en W, comme représenté notamment sur la
figure 2, simplement en écartant les ailes 1b, 1c l'une de l'autre, tout en pouvant bien
sûr reprendre une position d'utilisation en U en vue, par exemple, de fabriquer un
conteneur d'emballage réalisé à partir de deux profilés en U imbriqués l'un dans l'au<
tre.It is easily understood that the profiles thus obtained can take a
storage and / or transport position in W, as shown in particular on the
Figure 2, simply by spreading the
L'invention propose de très nombreux modes de réalisation comme le montrent notamment les figures 9 à 20, les dessins notés (a) représentant, comme déjà dit, les profilés en position d'utilisation et les dessins notés (b) les profilés en position de stockage et/ou de transport.The invention proposes numerous embodiments as shown in particular Figures 9 to 20, the drawings noted (a) representing, as already said, the profiles in position of use and the drawings noted (b) the profiles in position storage and / or transport.
La figure 9 montre un profilé du type de celui de la figure 3 avec une rainure
par enfoncement (laquelle pourrait en outre être réalisée avec une concavité sur la
face externe du fond 1a).Figure 9 shows a profile of the type of that of Figure 3 with a groove
by sinking (which could also be carried out with a concavity on the
external face of the
La figure 10 montre un profilé du type de celui de la figure 4 avec une rainure réalisée par enlèvement de matière.Figure 10 shows a profile of the type of that of Figure 4 with a groove made by removing material.
La figure 11 montre un mode de réalisation voisin de celui de la figure 10 mais dans lequel la rainure a été réalisée sur la face interne du fond du profilé.Figure 11 shows an embodiment similar to that of Figure 10 but in which the groove has been produced on the internal face of the bottom of the profile.
Les figures 12 et 13 correspondent respectivement aux figures 10 et 11 mais
dans ces modes de réalisation, la ligne de pliage a été renforcée par une bande de
renfort 10, 10' appliquée sur la face du fond du profilé qui est opposée à la face pour>
vue de la rainure formant la ligne de pliage. Figures 12 and 13 correspond respectively to Figures 10 and 11 but
in these embodiments, the fold line has been reinforced by a strip of
Comme le montrent bien les figures 12 et 13, la bande du renfort 10 est appliquée
sur une partie seulement de la largeur du fond, mais elle pourrait être appliquée
sur la totalité de la largeur dudit fond.As Figures 12 and 13 clearly show, the strip of
La figure 14 qui correspond à la figure 13, présente toutefois une enveloppe
11 qui vient renforcer la ligne de pliage, tout en enveloppant une grande partie du profilé
à l'exception de la face du fond pourvue de la rainure, un tel enveloppement pouvant
en outre avoir un effet de rigidification et/ou un but esthétique.Figure 14 which corresponds to Figure 13, however shows an
La figure 15 montre un profilé du type de celui de la figure 5 avec une ligne de pliage ou rainure réalisée par incision.Figure 15 shows a profile of the type of that of Figure 5 with a line of folding or grooving made by incision.
Les figures 16 et 17 montrent des profilés pourvus de rainures effectuées aussi par incision mais avec des bandes de renfort respectivement 12, 12' appliquées sur la face du fond pourvue de l'incision (figure 16) ou respectivement la face opposée à celle pourvue de ladite incision (figure 17) d'une manière correspondant dans ce dernier cas à la figure 13.Figures 16 and 17 show profiles with grooves made also by incision but with reinforcement strips respectively 12, 12 'applied on the bottom side with the incision (figure 16) or on the opposite side, respectively to that provided with said incision (Figure 17) in a corresponding manner in this last case in figure 13.
Dans le mode de réalisation de la figure 16 toutefois, l'invention propose une particularité intéressante.In the embodiment of FIG. 16, however, the invention proposes a interesting feature.
Pour permettre un pliage aisé (voir la vue b de la figure 16), la bande de renfort
12 présente au niveau de la rainure par incision un repli.To allow easy folding (see view b of Figure 16), the reinforcing
Pour obtenir le repli susmentionné (c'est-à-dire un double pli en zigzag), on peut utiliser bien sûr tout moyen convenable pour plier et fixer ladite bande après avoir effectué l'incision comme le montre plus en détail la figure 20.To obtain the abovementioned fold (i.e. a double zigzag fold), we may of course use any suitable means to fold and secure said strip after having make the incision as shown in more detail in Figure 20.
La figure 18 montre un profilé muni d'une rainure comme celles des figures 15 à 17 et correspond à la figure 14 quant à l'enveloppe référencée ici 13.Figure 18 shows a profile with a groove like those in the figures 15 to 17 and corresponds to FIG. 14 as for the envelope referenced here 13.
La figure 19 quant à elle, propose un mode de réalisation tout à fait particulier,
dans lequel le profilé en U est obtenu à partir de deux profilés 1', 1" en L réunis
par la tranche de l'une de leurs ailes au moyen d'une bande de jonction 14 rapportée
par exemple par collage sur l'une des faces desdites ailes, comme le montre bien la
figure 19.FIG. 19, for its part, proposes a very particular embodiment,
in which the U-shaped profile is obtained from two 1 ', 1 "L-shaped profiles joined together
by the edge of one of their wings by means of an attached joining
Par ailleurs et pour compléter ce dernier mode de réalisation, on peut en outre prévoir dans ce cas un joint de colle et/ou de latex et/ou de silicone, ou autre, ménagé entre les tranches desdites ailes et représenté ici en pointillé en vue d'améliorer l'effet charnière de ce mode de réalisation.Furthermore, and to complete this latter embodiment, it is also possible in this case provide a glue and / or latex and / or silicone, or other, joint provided between the edges of said wings and shown here in dotted lines in order to improve the pivotal effect of this embodiment.
L'invention concerne bien sûr d'autres modes de réalisation possibles que ceux représentés, tels que, par exemple, le mode de réalisation de la figure 9 avec une bande de renfort, le mode de réalisation de la figure 19 avec une bande de jonction plus enveloppante, etc.The invention naturally relates to other possible embodiments than those represented, such as, for example, the embodiment of FIG. 9 with a reinforcing strip, the embodiment of FIG. 19 with a joining strip more enveloping, etc.
