Definitions
- 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 side.
- 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.
- 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.
- 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.
- the method according to the invention is characterized, as set out in the characterizing part of the claim 1, in that it consists in depositing a veil thin glue on the first side of the second layer in controlled flow and viscosity conditions of the sticks so that the applied veil divides itself into clearing the mesh area and transforming into longitudinal and / or transverse cords.
- 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.
- the first face of the second layer is facing up, being for example horizontal or inclined, for removing the adhesive veil.
- 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 active layer 2 comprising, on the one hand, a base or base 3 and, on the other hand, loops 4 which protrude from one of the two faces of the base 3.
- the first support or reinforcement layer 1 is for example constituted by a thin flexible film, by example in polypropylene.
- the base 3 of the second layer 2 has a light, open mesh structure, and it usually consists of interlacing, knitting or by weaving, of longitudinal threads 5 (warp threads or chain) and 6 transverse threads (weft threads).
- the loops 4 are generally produced during the manufacture of base 3.
- base 3 i.e. wires 5 and 6 in the example considered, define relatively large meshes due to the open character or openwork from base 3, as mentioned above.
- these meshes can have a dimension or size of 0.5 mm to 3 mm.
- the laminating of layers 1 and 2 is done at using an adhesive which, according to the invention, is deposited on the face of the base 3 which is opposite to the face carrying the loops 4.
- the glue is deposited from a nozzle or analog 7 which extends transversely and immediately above of layer 2 on the move. For this removal of glue, layer 2 is in a horizontal or inclined position, and its glue receiving face is facing up.
- the glue is deposited on the base 3, initially in the form of a continuous and full veil 8.
- Conditions are carefully controlled and predetermined as for the flow rate and viscosity of the adhesive, in general a hot-melt adhesive, so that, after its removal, the veil 8 is divides, breaks up or breaks up on its own, to transform into longitudinal and / or transverse cords corresponding, respectively, to wires 5 and 6.
- This division, disaggregation or dislocation is explained by the surface tension and capillarity phenomena.
- the glue bridges between the wires tend to become thinner and to break, so that the glue is concentrated by capillarity only on the structural elements of the base 3, i.e.
- wires 5 and 6 forming cords of longitudinal and / or transverse glue which define by example a network, grid or grid, like schematically represented in 9 in dashes. According to the title of wires 5 and 6, the glue is concentrated on the chain wires 5 or on the weft threads 6, or on these two types of son.
- the two layers 1 and 2 pass immediately after in a calendering station, in which they are pressed against each other, the cords glue, which can be found at the top of the base 3, ensuring the joining of the two layers.
- 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 polyamide knit 2 with a 1.5 mm mesh opening and a grammage of 20 g / m 2 , and an adhesive deposit rate of 2 g / m 2 , without observing the slightest sticking of the loops 4.
- 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.
- the layer support 1 can be the article itself.
- the glue carried by layer 2 or else an adhesive is used which, after drying or hardening, can be reactivated, for example at hot, or else, for winding layer 2 into a coil, we use a removable adhesive protection film which remains active or we apply to loops 4 a coating of non-stick agent to make the adhesive inactive compared to the loops.

Abstract
Description
Claims (7)
- Procédé de fabrication d'un ensemble stratifié comportant une première couche (1) dont une face est solidarisée à l'aide de colle avec une première face d'une seconde couche (2) qui présente une structure à mailles et qui porte sur sa seconde face des boucles libres (4) faisant saillie de cette seconde face, caractérisé en ce qu'il consiste à déposer un voile mince (8) de colle sur la première face de la seconde couche (2) dans des conditions contrôlées de débit et de viscosité de la colle pour que le voile déposé se divise de lui-même en dégageant la zone des mailles et en se transformant en des cordons longitudinaux et/ou transversaux (9).
- Procédé selon la revendication 1, caractérisé en ce que la colle est déposée sur la seconde couche (2) par une buse (7) sous la forme d'un voile (8) initialement continu et plein.
- Procédé selon l'une des revendications 1 et 2, caractérisé en ce que la seconde couche (2) est un tissu à boucles tricoté ou tissé.
- Procédé selon l'une des revendications 1 à 3, caractérisé en ce que les mailles présentent une dimension de 0,5 à 3 mm.
- Procédé selon l'une des revendications 1 à 4, caractérisé en ce que, pour la dépose du voile de colle (8), la première face de la seconde couche (2) est tournée vers le haut, en étant horizontale ou inclinée.
- Procédé selon l'une des revendications 1 à 5, caractérisé en ce que l'opération proprement dite de contrecollage est effectuée immédiatement après la dépose de la colle.
- Procédé selon l'une des revendications 1 à 5, caractérisé en ce que l'opération proprement dite de contrecollage est effectuée ultérieurement, la colle étant soit réactivée après séchage ou durcissement, soit protégée par une pellicule amovible, soit rendue inactive à l'égard des boucles, notamment par une enduction de celles-ci à l'aide d'un agent anti-adhérent.
