Description
La présente invention est relative aux ensembles stratifiés, ou laminés, qui comportent une première couche dont une face est solidarisée par contrecollage avec une première face d'une seconde couche à mailles comprenant des boucles libres qui font saillie de l'autre face de cette seconde couche.The present invention relates to assemblies laminates, or laminates, which have a first layer one side of which is secured by laminating with a first face of a second mesh layer comprising free loops protruding from the other side of this second layer.
L'invention s'applique en particulier à de tels ensembles qui sont souples et qui sont utilisés pour la confection, par exemple sous la forme de bandes, de la partie femelle d'une fermeture dite auto-agrippante, dont les boucles sont destinées à coopérer, dans une liaison séparable d'accrochage, avec des éléments mâles complémentaires, par exemple des crochets, des éléments filiformes à tête renflée ou analogues, etc. Ces parties femelles de fermeture auto-agrippantes sont utilisées notamment pour les couches-culottes.The invention applies in particular to such sets that are flexible and that are used for the making, for example in the form of strips, the part female of a so-called hook-and-loop closure, the loops are intended to cooperate, in a separable connection attachment, with complementary male elements, by example of hooks, filiform elements with bulging heads or the like, etc. These female hook and loop closure parts are used in particular for diapers.
Pour des raisons de prix de revient, on est amené à fabriquer la base de la seconde couche sous une forme légère et ouverte, c'est-à-dire à mailles, et donc d'une structure mécaniquement fragile et dimensionnellement instable, sans pour autant sacrifier la qualité des boucles qui constituent l'élément actif primordial dé la partie femelle de la fermeture auto-agrippante. Cette fragilité et cette instabilité de la base induisent des difficultés de mise en oeuvre, notamment pour positionner et fixer à grande vitesse cette partie femelle sur son support, ainsi que des difficultés d'utilisation, en raison des sollicitations d'arrachement relativement importantes auxquelles la base est soumise et qui proviennent de l'action des éléments mâles d'accrochage sur les boucles. For cost reasons, we are led to fabricate the base of the second layer in a light form and open, that is to say with mesh, and therefore of a structure mechanically fragile and dimensionally unstable, without however sacrifice the quality of the loops which constitute the primary active element of the female part of the Velcro closure. This fragility and this instability of the base induce difficulties in setting work, especially for positioning and fixing at high speed this female part on its support, as well as difficulties of use, due to stress relatively large pullout at which the base is subject and which come from the action of the male elements hooking on the loops.
On est donc conduit à renforcer la base en la contrecollant sur une couche de support plus résistante, par exemple une pellicule pleine, fine et souple. Cette couche de support peut être un support intermédiaire, l'ensemble stratifié étant ensuite fixé sur un article, ou bien il peut être l'article lui-même.We are therefore led to strengthen the base by laminating on a more resistant support layer, by example a full, thin and flexible film. This layer of support may be an intermediate support, the assembly laminate then being attached to an article, or else it can be the article itself.
Toutefois, on rencontre des difficultés, lors de la fabrication d'un tel ensemble stratifié, car les boucles ont tendance à se coller également sur la couche de support, à travers les mailles, conjointement avec la matière de la base, ce qui affecte leur pouvoir auto-agrippant du fait que leur sommet est fermement plaqué contre la base et/ou la couche de support et ne peut donc pas coopérer, dans la liaison d'accrochage- voulue, avec les éléments mâles. En effet, en général, pour réaliser ce laminage, on est amené à presser fortement les deux éléments de l'ensemble l'un contre l'autre, par exemple à l'aide de calandres.However, difficulties are encountered during the manufacture of such a laminate assembly, because the loops have tendency to stick also on the support layer, through the mesh, together with the material of the base, which affects their hook-and-loop power because their top is firmly pressed against the base and / or the support layer and therefore cannot cooperate, in the attachment link - desired, with male elements. In Indeed, in general, to carry out this rolling, one is brought to strongly press the two elements of the whole one against the other, for example using calenders.
Dans le document EP-A-0.278.866 (D1), qui concerne également une structure ajourée à boucles, on prévoit l'application d'une pellicule de résine synthétique qui forme un écran entre la structure à mailles et le support sur lequel l'ensemble sera ultérieurement collé. Pour éviter que, à son tour, la résine synthétique ne traverse la structure à mailles, on prévoit une résine d'une viscosité suffisante pour éviter une telle traversée. Cette technique impose l'utilisation d'une grande quantité de matière de résine puisque celle-ci doit constituer un écran.In document EP-A-0.278.866 (D1), which relates also an openwork structure with loops, applying a synthetic resin film which forms a screen between the mesh structure and the support on which the assembly will later be glued. To avoid that, in turn, the synthetic resin does not pass through the structure to mesh, a sufficient viscosity resin is provided to avoid such a crossing. This technique requires the use of a large amount of resin material since it must be a screen.
L'ensemble stratifié de ce document D1 est compliqué à réaliser, nécessitant l'utilisation d'une colle à propriétés variables en fonction de la température. En outre, au-delà de 50°, les boucles ont de nouveau tendance à se coller contre la couche de colle.The whole laminate of this document D1 is complicated to perform, requiring the use of a glue variable properties depending on the temperature. In addition, beyond 50 °, the loops again tend to get stick against the glue layer.
Dans le document EP-A-0.258.015 (D2), il s'agit de renforcer une structure souple fibreuse et poreuse portant des boucles. Pour cela, on applique au dos de cette structure une couche de résine thermoplastique. Cette résine a pour rôle d'ancrer les filaments de la structure fibreuse en renforçant la tenue des boucles. Ce document ne se préoccupe pas d'empêcher la traversée de la structure par la résine. In document EP-A-0.258.015 (D2), it is a question of reinforce a flexible fibrous and porous structure bearing curls. For this, we apply to the back of this structure a layer of thermoplastic resin. This resin has for role of anchoring the filaments of the fibrous structure in strengthening the hold of the curls. This document is not concerned not to prevent the crossing of the structure by the resin.
L'invention a pour but de remédier à cet inconvénient en fournissant un procédé de contrecollage qui permet, de manière fiable, simple et économique, de contrecoller la première couche, ou couche de support, sur la seconde couche à l'aide de colle sans que les boucles soient intéressées par la colle.The invention aims to remedy this disadvantage in providing a laminating process which allows, reliably, simply and economically, laminate the first layer, or support layer, on the second layer using glue without loops being interested in glue.
A cet effet, le procédé selon l'invention est tel que défini à la revendication 7.To this end, the method according to the invention is such as defined in claim 7.
Des modes de réalisation avantageux du procédé sont

Ainsi, dans le procédé selon l'invention, d'une part, la colle est déposée sur la seconde couche, et non pas sur la première couche, et, d'autre part, elle est déposée de telle façon que le voile ou pellicule de colle, initialement déposé sous une forme continue et pleine, se divise ou se désagrège de lui-même, par effet de tension superficielle, en dégageant la zone des mailles, pour que la colle ne soit retenue, par capillarité, que sur une partie au moins des éléments structurels de la base de la seconde couche, en général des fils du fait que cette seconde couche est d'habitude constituée par un tissu à boucles qui est tricoté ou tissé.Thus, in the method according to the invention, of a hand, the glue is deposited on the second layer, not on the first layer, and, on the other hand, it is deposited from so that the veil or film of glue, initially deposited in a continuous and full form, divides or forms disintegrates of itself, by surface tension effect, in clearing the mesh area, so that the glue is not retained by capillarity only on at least part of the structural elements of the base of the second layer, in general threads because this second layer is usually a loop fabric that is knitted or woven.
Avantageusement, la première face de la seconde couche est orientée vers le haut, en étant par exemple horizontale ou inclinée, pour la dépose du voile de colle.Advantageously, the first face of the second layer is facing up, being for example horizontal or inclined, for removing the adhesive veil.
On comprendra bien l'invention à la lecture du complément de description qui va suivre et en référence au dessin annexé qui fait partie de la description et dont la Figure 1 unique est une coupe transversale schématique illustrant la mise en oeuvre du procédé selon l'invention. The invention will be clearly understood on reading the additional description which follows and with reference to attached drawing which forms part of the description and the Single Figure 1 is a schematic cross section illustrating the implementation of the method according to the invention.
La Figure représente un ensemble stratifié, par
exemple immédiatement avant l'opération proprement dite de
contrecollage, les deux couches constitutives de cet ensemble
stratifié étant donc représentées séparées. Cet ensemble
comporte une première couche 1 de support et une seconde
couche active 2 comportant, d'une part, un fond ou base 3 et,
d'autre part, des boucles 4 qui font saillie à partir de
l'une des deux faces de la base 3.The Figure represents a stratified set, by
example immediately before the actual operation of
laminating, the two constituent layers of this set
laminate therefore being shown separate. This set
has a first support layer 1 and a second
La première couche 1 de support ou de renforcement
est par exemple constituée par une fine pellicule souple, par
exemple en polypropylène. La base 3 de la seconde couche 2
présente une structure légère et ouverte à mailles, et elle
est en général constituée par l'entrelacement, par tricotage
ou par tissage, de fils longitudinaux 5 (fils de chaíne ou de
chaínette) et de fils transversaux 6 (fils de trame). Les
boucles 4 sont en général réalisées lors de la fabrication de
la base 3.The first support or reinforcement layer 1
is for example constituted by a thin flexible film, by
example in polypropylene. The
Les éléments structurels de la base 3, c'est-à-dire
les fils 5 et 6 dans l'exemple considéré, définissent des
mailles relativement grandes en raison du caractère ouvert ou
ajouré de la base 3, comme mentionné ci-dessus. Par exemple,
ces mailles peuvent avoir une dimension ou taille de 0,5 mm à
3 mm.The structural elements of
Le contrecollage des couches 1 et 2 se fait à
l'aide d'une colle qui, selon l'invention, est déposée sur la
face de la base 3 qui est opposée à la face portant les
boucles 4. La colle est déposée à partir d'une buse ou
analogue 7 qui s'étend transversalement et immédiatement au-dessus
de la couche 2 en déplacement. Pour cette dépose de
colle, la couche 2 est en position horizontale ou inclinée,
et sa face de réception de la colle est tournée vers le haut.The laminating of
La colle est déposée sur la base 3, initialement
sous la forme d'un voile 8 continu et plein. Les conditions
opératoires sont soigneusement contrôlées et prédéterminées
quant au débit et à la viscosité de la colle, en général une
colle thermofusible, pour que, après sa dépose, le voile 8 se
divise, se désagrège ou se disloque de lui-même, pour se
transformer en des cordons longitudinaux et/ou transversaux
correspondant, respectivement, aux fils 5 et 6. Cette
division, désagrégation ou dislocation s'explique par les
phénomènes de tension superficielle et de capillarité. En
effet, dans la zone libre ou dégagée des mailles de la base
3, les ponts de colle entre les fils ont tendance à s'amincir
et à se briser, de sorte que la colle se concentre par
capillarité seulement sur les éléments structuraux de la base
3, c'est-à-dire les fils 5 et 6, en formant des cordons de
colle longitudinaux et/ou transversaux qui définissent par
exemple un réseau, un quadrillage ou une grille, comme
schématiquement représenté en 9 en tirets. Selon le titre des
fils 5 et 6, la colle se concentre sur les fils de chaíne 5
ou sur les fils de trame 6, ou encore sur ces deux types de
fils.The glue is deposited on the
Dans l'exemple adopté, les deux couches 1 et 2
passent immédiatement après dans un poste de calandrage, dans
lequel elles sont pressées l'une contre l'autre, les cordons
de colle, qui se trouvent à la partie supérieure de la base
3, venant assurer la solidarisation des deux couches.In the example adopted, the two
Lors de ce calandrage, du fait que la colle active
est située, en quantité dosée, seulement sur les éléments
structuraux de la base 3 et à l'opposé des boucles 4, elle ne
peut pas interférer avec celles-ci, de sorte que les boucles
restent libres ou dégagées, c'est-à-dire qu'elles ne sont pas
collées et que, par conséquent, leur pouvoir accrochant reste
intact.During this calendering, because the active glue
is located, in quantity dosed, only on the elements
structural of the
Grâce au fait que les boucles ne sont pas affectées
par le collage, on peut réduire, par exemple jusqu'à 50 %, le
grammage de la couche 2 sans diminuer pour autant la capacité
d'accrochage des boucles, ce qui entraíne une réduction
avantageuse des prix de revient. Thanks to the fact that the loops are not affected
by gluing, you can reduce, for example up to 50%, the
weight of
Dans un exemple pratique de réalisation, on a
utilisé une pellicule 1 en polypropylène, une colle
thermofusible à base de polyuréthane, une buse transversale 7
d'une largeur d'ouverture de 0,4 mm, un tricot 2 polyester ou
polyamide d'une ouverture de mailles de 1,5 mm et d'un
grammage de 20 g/m2, et un débit de dépose de colle de 2
g/m2, sans observer le moindre collage des boucles 4.In a practical embodiment, a polypropylene film 1 was used, a polyurethane-based hot-melt adhesive, a transverse nozzle 7 with an opening width of 0.4 mm, a polyester or
Bien entendu, l'invention n'est pas limitée au mode
de mise en oeuvre qui a été décrit; on pourrait au contraire
concevoir diverses variantes sans sortir pour autant de son
cadre. Par exemple, l'opération proprement dite de
contrecollage pourrait être faite ultérieurement, sur le site
de fabrication de l'article lui-même. Dans ce cas, la couche
de support 1 peut être l'article lui-même. Quant à la colle
portée par la couche 2, ou bien on utilise une colle qui,
après séchage ou durcissement, est réactivable, par exemple à
chaud, ou bien, pour l'enroulement de la couche 2 en bobine,
on utilise une pellicule amovible de protection de la colle
qui reste active ou on applique sur les boucles 4 une
enduction d'agent anti-adhérent pour rendre l'adhésif inactif
par rapport aux boucles.Of course, the invention is not limited to the mode
of implementation which has been described; we could on the contrary
design various variants without departing from its
frame. For example, the actual operation of
laminating could be done later, on the site
of manufacturing the item itself. In this case, the layer
support 1 can be the article itself. As for the glue
