Abstract
Description
Assemblage Par couture de deux bords de toile synthétique se recouvrant et obiet notamment toile de tente, muni d'un tel assemblage.Assembly By sewing two edges of synthetic canvas overlapping and obiet in particular tent canvas, provided with such an assembly.
La présente invention concerne des perfectionnements apportés à l'assemblage par couture de deux bords de toile synthétique se recouvrant. The present invention relates to improvements made to the assembly by sewing of two overlapping edges of synthetic fabric.
Dans ce qui suit, on entend par "toile synthétique" aussi bien un tissu ou tissé ou toile tissée en un fil synthétique qu'un non tissé ou film constitué en une matière synthétique. Plus généralement, on entend désigner également les toiles simples ou à une seule épaisseur et les toiles à épaisseurs multiples (plusieurs épaisseurs d'un même type de toile, tissé ou non tissé ; plusieurs épaisseurs de toile de types différents, tissé et non tissé ; voire association d'une toile et d'un film souple métallique -aluminium notamment-). In what follows, the term "synthetic fabric" means both a fabric or woven or fabric woven from a synthetic yarn as a nonwoven or film made of a synthetic material. More generally, it is also intended to denote single or single-ply fabrics and fabrics with multiple thicknesses (several thicknesses of the same type of canvas, woven or nonwoven; several thicknesses of canvas of different types, woven and nonwoven; or even a combination of a canvas and a flexible metallic film - aluminum in particular-).
Dans un assemblage traditionnel par couture de deux bords 1 et 2 de toile synthétique disposés à recouvrement comme illustré très schématiquement à la figure 1 du dessin annexé (sur lequel les bords sont supposés assemblés par une double couture à deux rangs parallèles 3), chaque trou d'aiguille à travers la toile est géométriquement stable autrement dit, chaque trou d'aiguille conserve la dimension transversale correspondant au diamètre de l'aiguille traversant la toile, et il ne se produit pas de rétraction du matériau et de résorbtion du trou comme cela arrive lors de la couture de tissu en fibres naturelles. In a traditional assembly by sewing two edges 1 and 2 of synthetic fabric arranged overlapping as illustrated very schematically in Figure 1 of the accompanying drawing (on which the edges are assumed to be assembled by a double seam with two parallel rows 3), each hole needle through the fabric is geometrically stable in other words, each needle hole retains the transverse dimension corresponding to the diameter of the needle passing through the fabric, and there is no shrinking of the material and resorption of the hole like this happens when sewing natural fiber fabric.
I1 en résulte que, lorsqu'un tel assemblage reçoit une projection de liquide sur une de ses faces (cas notamment d'une toile de tente sous la pluie), chaque trou d'aiguille constitue une fuite. Un tel assemblage n'est pas étanche. I1 follows that, when such an assembly receives a projection of liquid on one of its faces (case in particular of a tent in the rain), each needle hole constitutes a leak. Such an assembly is not waterproof.
En outre, sous l'action des tensions mécaniques pouvant s'exercer sur les deux bords de tissu ainsi assemblés, les trous ont tendance à s'élargir progressivement, ce qui accroit le défaut d'étanchéité. In addition, under the action of mechanical stresses which can be exerted on the two edges of fabric thus assembled, the holes tend to widen gradually, which increases the sealing defect.
Pour tenter d'éliminer cet inconvénient, on a déjà proposé d'adjoindre, sur la couture, une bande 4 d'un matériau synthétique apposé (collage, soudage, thermosoudage) sur la face intérieure (c'est-à-dire la face non soumise à la projection de liquide) de l'assemblage, comme illustré très schématiquement à la figure 2 du dessin annexé. Une telle bande permet, certes, d'obturer les trous d'aiguille et devrait par conséquent être en mesure de procurer l'étanchéité souhaitée. In an attempt to eliminate this drawback, it has already been proposed to add, on the seam, a strip 4 of an affixed synthetic material (bonding, welding, heat-sealing) on the inner face (that is to say the face not subject to the projection of liquid) of the assembly, as illustrated very schematically in Figure 2 of the accompanying drawing. Such a strip certainly allows to close the needle holes and should therefore be able to provide the desired seal.
Toutefois, la tenue dans le temps de la fixation de cette bande, notamment thermosoudée, est médiocre et elle finit par se décoller, ce qui rend l'assemblage des bords de tissu non étanche comme dans le cas précédent. However, the resistance over time of the fixing of this strip, in particular heat-sealed, is poor and it eventually peels off, which makes the assembly of the edges of fabric not waterproof as in the previous case.
De plus, étant collée ou thermosoudée, la bande en matière synthétique ne renforce pas réellement l'assemblage sur le plan mécanique. In addition, being glued or heat-sealed, the plastic band does not really reinforce the assembly mechanically.
Enfin, la fabrication nécessite plusieurs étapes (couture des bords, collage ou thermosoudage de la bande) et se révèle longue, difficile et onéreuse. Finally, the production requires several steps (sewing the edges, gluing or heat-sealing the strip) and proves to be long, difficult and expensive.
L'invention a essentiellement pour but de remédier aux inconvénients précités des solutions actuellement connues et de proposer un assemblage perfectionné étanche, mécaniquement résistant, fiable dans le temps, simple et peu coûteux à fabriquer. The object of the invention is essentially to remedy the aforementioned drawbacks of currently known solutions and to propose an improved tight assembly, mechanically resistant, reliable over time, simple and inexpensive to manufacture.
A ces fins, un assemblage par couture de deux bords de toile synthétique se recouvrant se caractérise essentiel lement, étant agencé conformément à l'invention, en ce qu'une bande constituée en une matière apte à gonfler au contact d'un liquide, notamment d'eau, est disposée par dessus un des bords (non soumis aux projections de liquide) de toile et est cousue en même temps et dans la même couture que lesdits bords de toile se recouvrant. Avantageusement, la bande est constituée en une matière hydrophile. For these purposes, an assembly by sewing of two overlapping edges of synthetic fabric is essentially characterized, being arranged in accordance with the invention, in that a strip made of a material capable of swelling on contact with a liquid, in particular of water, is arranged over one of the edges (not subject to liquid splashes) of canvas and is sewn at the same time and in the same seam as said overlapping canvas edges. Advantageously, the strip is made of a hydrophilic material.
De préférence, la matière constitutive de la bande est du coton ou un polycoton, matériaux expansibles, hydrophiles et peu coûteux. Preferably, the constituent material of the strip is cotton or a polycotton, expandable, hydrophilic and inexpensive materials.
Grâce aux dispositions conformes à l'invention, la bande est solidarisée par couture, en même temps et par les mêmes coutures que les deux bords de tissu à assembler. On conserve donc l'avantage d'une étape d'assemblage unique, et le coût de la fabrication n'est pas sensiblement accru. Thanks to the arrangements according to the invention, the strip is joined by sewing, at the same time and by the same seams as the two edges of fabric to be assembled. The advantage of a single assembly step is therefore retained, and the cost of manufacture is not significantly increased.
Par ailleurs, en raison de l'accroissement de volume subi par la bande au contact du liquide passant par les trous d'aiguille, cette bande, retenue par ailleurs par le fil de couture, est plaquée contre les trous d'aiguilles et les obture de manière étanche en empêchant le liquide de s'écouler continuement sur la face correspondante de l'assemblage et de la toile. Furthermore, due to the increase in volume undergone by the strip in contact with the liquid passing through the needle holes, this strip, which is also retained by the sewing thread, is pressed against the needle holes and blocks them. sealingly by preventing the liquid from continuously flowing over the corresponding face of the assembly and of the fabric.
De plus, en ayant recours à un matériau hydrophile tel que le coton ou le polycoton, le peu de liquide qui parvient, à travers les trous, au contact de la bande est retenue par cette dernière. In addition, by using a hydrophilic material such as cotton or polycotton, the little liquid which reaches, through the holes, in contact with the strip is retained by the latter.
Egalement, du fait même de son assemblage par couture avec les bords assemblés de tissu, la bande contribue à renforcer cet assemblage sur le plan mécanique et constitue un renfort qui participe à la solidité de l'ensem- ble. Elle reprend, au moins en partie, les efforts de tension auxquels peuvent être soumis les bords assemblés et empêche ainsi les trous de s'agrandir. Also, by the very fact of its assembly by sewing with the assembled edges of fabric, the strip contributes to reinforcing this assembly on the mechanical level and constitutes a reinforcement which contributes to the solidity of the assembly. It takes up, at least in part, the tension forces to which the assembled edges may be subjected and thus prevents the holes from growing.
Enfin, la fixation de la bande n'est pas altérable dans le temps. L'étanchéité et la solidité de l'assemblage sont donc fiables. Finally, the fixing of the strip is not alterable over time. The tightness and solidity of the assembly are therefore reliable.
L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode de réalisation préféré donné uniquement à titre d'exemple non limitatif, en référence à la figure 3 du dessin annexé qui illustre de façon très schématique un assemblage effectué conformément à l'invention. The invention will be better understood on reading the detailed description which follows of a preferred embodiment given solely by way of nonlimiting example, with reference to FIG. 3 of the appended drawing which very schematically illustrates an assembly carried out according to the invention.
Comme représenté à la figure 3 en conservant les mêmes références numériques que précédemment, une bande 5 constituée en une matière apte à gonfler au contact d'un liquide, notamment d'eau, et de préférence hydrophile, -tel que le coton ou le polycoton- est disposée par-dessus un des bords de toile (sur la toile 2 sur la figure 3), à savoir celui qui n'est pas soumis à une projection de liquide et que l'on désignera par "face intérieure" dans ce qui suit. As shown in FIG. 3, keeping the same reference numbers as above, a strip 5 made of a material capable of swelling on contact with a liquid, in particular water, and preferably hydrophilic, such as cotton or polycotton. - is arranged over one of the edges of the fabric (on the fabric 2 in FIG. 3), namely that which is not subjected to a projection of liquid and which will be designated by "inner face" in what follows.
La bande 5 est cousue en même temps que les deux bords se recouvrant des toiles 1 et 2 et est prise dans les mêmes coutures 3.The strip 5 is sewn at the same time as the two overlapping edges of the fabrics 1 and 2 and is taken in the same seams 3.
Dans l'exemple représenté à la figure 3, la couture 3 est double, avec deux rangs de couture parallèles prenant simultanément les deux toiles 1 et 2 et la bande 5. Bien entendu, le mode d'assemblage conforme à l'invention est indépendant du nombre de rang de couture mis en oeuvre. In the example shown in FIG. 3, the seam 3 is double, with two rows of parallel seams simultaneously taking the two fabrics 1 and 2 and the strip 5. Of course, the method of assembly according to the invention is independent the number of sewing rows used.
Les deux bords de toile 1 et 2 peuvent appartenir à un même morceau de toile refermé sur lui-même pour constituer un élément étanche fermé (cylindre, poche ou sac), ou bien appartenir à deux morceaux de toile distincts et adjacents réunis pour constituer un objet ou partie d'objet en toile de plus grande dimension, comme ctest le cas pour la fabrication d'une tente, et notamment d'un double toit de tente destiné à recevoir extérieurement la pluie. Les deux bords de toile 1 et 2 peuvent être identiques ou différents (tissu tissé en un fil synthétique, film en matière synthétique, association de plusieurs couches de même nature ou de natures différentes, voire association avec un film métallique tel que l'aluminium). The two edges of canvas 1 and 2 can belong to the same piece of canvas closed in on itself to constitute a closed waterproof element (cylinder, pocket or bag), or else belong to two separate and adjacent pieces of canvas joined together to constitute a larger object or part of an object made of canvas, as is the case for the manufacture of a tent, and in particular a double tent roof intended to receive rain externally. The two edges of the fabric 1 and 2 can be identical or different (fabric woven from a synthetic yarn, film made of synthetic material, association of several layers of the same nature or of different natures, or even association with a metallic film such as aluminum) .
Comme il va de soi et comme il résulte déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés ; elle en embrasse au contraire toutes les variantes. As is obvious and as already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, it embraces all its variants.
