Banda Profilée en mati.r..r.nth4t1que th.rmop1&.'iq'Í servant à contioctur deux touilles textiles,
La présente invention concerne une bande ou applique profilée en matière synthétique thermoplastique servant à connecter deux fouilles textiles recouvertes sur les deux cet'. de matière synthétique thermoplastique.
Des textiles très résistants recouverts sur les deux côté de matière synthétique thermoplastique sont utilisés de plus en plus car ils sont de loin supérieurs aux textiles non recouverts au point de vue de la résistance au récuras., de la résistance aux intempéries, de l'étanchéité aux gaz et à l'eau et analogues.
La formation de joints d'assemblage lorsqu'on place deux feuilles
<Desc/Clms Page number 2>
textiles l'une contre l'autre constitue un problème important,
Comme procédé pour la formation de jointe d'assemblage, on connaît la couture, l'agrafage, le collage, la vulcanisation à froid de matières de recouvrement appropriées,et la soudures
Tandis que la couture et l'agrafage par le fait que les feuillet de textiles recouvertes sont simultanément saisies, conduisent à des joint% de couture relativement solides, mail en général non étanches ou du moins à la formation de joints qui deviennent non étanches avec le tempe, on obtient par collage, vulcanisation ou soudure un joint étanche ; cependant la connexion /ne fait qu'en surface, de sorte que les textiles ne sont pas saisie en même tempe.
On peut en principe choisir la largeur de la connexion par soudure de telle manière que la résistance se rapproche à peu près de celle de toute la matière, mais dans la pratique cela est difficilement réalisable. A cela U faut ajouter que dans la plupart des soudure$ usuelles à recouvrement, en plus de la sollicitation au cisaille* ment on facilite la rupture au Joint obtenu par soudure, de telle sorte q'un moment de rotation se produit qui fait tourner l'en- droit de soudure même.
à l'égard de la direction de la traction et on produit ainsi un certain effet de coin au défaut du recouvrement*
Par la bande ou applique profilée en matière synthétique thermoplastique selon la présente invention on évite les inconvé- nient* qui se produisent dans les procédés de soudure connus. La bande profilée en matière synthétique thermoplastique selon la présente invention servant à connecter deux feuilles de tissu recouvertes est conformée de telle manière qu'elle entoure complè- tement les borde des deux feuilles qui doivent être connectées entre elles *et est soudée sur les deux côtés aux recouvrements thermo- plastiques.
De cette manière, le dimensionnement du Joint de soudure
<Desc/Clms Page number 3>
pour que les endroits soudée présentent la mime résistance que la feuille de tissu, est grandement facilite. De plus, par utili- sation d'une applique dont la section est celle d'un H étroit;, haut, en forme d'un H majuscule, les bords de la feuille textile dont entourée par les bras du H qui saisissent sur les deux côtés, et de cette manière on évite également le moment de rotation dans le joint de couture qui faciliterait la rupture. Bien entendu, d'autres formes de la section sont également possibles, Ainsi, la bande en matière synthétique peut présenter par exemple une forme en Z ou en S, ainsi que la forme d'un 3 ou d'un U.
Alors que dans de nombreux cas il est usuel de fabriquer en matières différentes les couche% de recouvrement interne et externe d'une feuille textile selon les conditions imposées au produit fini, les deux matériaux utilisés n'étant pas toudables entre eux sans prendre des mesures spéciales, une soudure de recouvrement est extraordinairement difficile. Pour cette raison, on a le plus souvent recours dans la pratique au collage.
Selon la présente invention une soudure est rendue possible ici aussi, notamment par le fait que l'on constitue la bande en matière synthétiquo en deux parti.. qui consistent chacune en la matière de recouvrement et on les colle l'une à l'autre au milieu ou par des dispositifs connus en sci, par exemple à queue d'aronde, d'une manière analogue à celle d'un bouton à pression. Lorsqu'une soudure des deux Couche% différentes entre elles est possible, on peut bien entendu souder les deux moitiés de la bande. La longueur des parties ou pattes qui entourent les bords de la bande textile est avantageusement de 43 à 15 fois l'épaisseur de la feuille textile.
Dans de nombreux cas, par exemple pour les réservoir$
<Desc/Clms Page number 4>
flottants,il peut être nécessaire d'utiliser des bandes ou appliques en matière synthétique qui soient luminescentes, Cela peut être obtenu d'une manière simple en incorporant des matières luminescentes dans la masse d'injection,
Pour l'assemblage mécanique des feuillet il est avanta- geux d'utiliser autant que possible des appliques transparentes ou translucides , car alors on peut surveiller facilement l'in- sertion des bords jusqu'au fond, La bande peut être formée de 2 moitiés,
assemblées entre elles à ressort ou déclics
La bande synthétique thermoplastique selon l'invention sera maintenant expliquée de plus près en se reportant aux dessine oi-jointe qui montrent divers mode. de réalisation,
Dans ces dessins , les figures 1 et 4 montrent des formes simples de la bande en matière synthétique en forme de H,
Les figures 2 et 3 montrent deux formes ayant une autre section que la section en H.
La figure 5 montre une bande formée de deux bandes as- semblées! et . la figure 6 montre une forme collée ou soudée consistant en plusieurs partions
La bande en matière synthétique en forme de H selon les figures 1 et 4 consiste en une partie médiane 1;17 et en ré- glottes 2,3; 18,19, formant l'encoche qui doit recevoir les feuilles en matière synthétique à souder.
Les feuilles 4;5 en matière synthétique renforcées par les feuilles de textile 6;7 sont introduites dans les encoches forcées entre les réglettes et sont soudées, en utilisant des méthodes connues en soi,
<Desc/Clms Page number 5>
Cela peut se faire par exemple aux endroits montrés dans les dessins en traite en pointillé, mais peut faire également aur toute la surface de contact.
Ainsi qu'on peut le voir des figures 2 et 3, la bande en matière synthétique selon la présente invention peut présenter n'importe quelle section adapté. aux nécessités du moment. La figure 2 montre une section en forme de 2 dans laquelle la réglette médiane se trouvant placée entre les deux touilles en matière synthétique est connectée au moyen des éléments 11 et 12 avec les réglettes 9 et 10. Dans la figure 3 on a Illustré une bande h section en 3 dans laquelle le dos 13 présente trois réglettes 14,15 et 16.
Dans les cas ou pour le recouvrement de la feuille textile on doit employer deux matières différentes* il peut être avanta- geux de constituer la bande en matière synthétique en le* mômes matières, Selon la présente invention il existe pour cela deux possibilités préférentielles qui sont illustrées dans les figures 5 et 6. La bande en matière synthétique selon la figure 5 consis- té en une partie inférieure 20, 23 avec la latte 21 faisant saillie à la partie médiane 20, et la partie supérieure 22, 24 avec les enfoncements 25 présente dans la partie médiane 22 et correspondant aux lattes 21.
Après quel-éventuellement par une légère déformation de la partie supérieure-, les deux parties de la bande en matière synthétique ont été assemblées* on effec- tue l'introduction des deux feuilles en matière synthétique consistant en deux couches différentes de matière synthétique 26 et 27, ainsi que la soudure.
Une autre possibilité pour la formation d'aune bande en deux matériaux différents est montrée dans la figure 6. La bande
<Desc/Clms Page number 6>
en matière synthétique consiste en parties 28, 29, 30, et 31, où 26, 28 et 30, ou 27,29 et 31 sont respectivement constituées en une matière synthétique de même nature. Les parties 30, 31 ensuite 28 avec 30 et 29 avec 31 sont d'abord assemblées par collage ou soudure. Ensuite le travail se fait de la môme manière que dans les autres formes décrites,

EMI1.1
Banda profiled in mati.r..r.nth4t1que th.rmop1 &. 'Iq'Í serving to contioctur two textile stems,
The present invention relates to a strip or profiled applique in thermoplastic synthetic material serving to connect two textile excavations covered on both this'. of thermoplastic synthetic material.
Highly resistant textiles coated on both sides with thermoplastic synthetic material are used more and more because they are far superior to uncoated textiles from the point of view of scouring resistance, weather resistance, waterproofing. gas and water and the like.
The formation of assembly joints when placing two sheets
<Desc / Clms Page number 2>
textiles against each other is a significant problem,
As a method for forming joint seams, stitching, stapling, gluing, cold vulcanization of suitable cover materials, and welding are known.
While sewing and stapling by the fact that the covered textile leaflets are simultaneously gripped, lead to relatively strong seam joints, which are generally not waterproof or at least to the formation of joints which become leaky with the seam. temple, a tight seal is obtained by bonding, vulcanization or welding; however the connection / is only on the surface, so that the textiles are not gripped at the same time.
In principle, the width of the solder connection can be chosen so that the resistance approximates that of the whole material, but in practice this is difficult to achieve. To this must be added that in most of the usual lap welds, in addition to the shear stress, the rupture of the joint obtained by welding is facilitated, so that a torque is produced which causes the joint to rotate. even weld place.
with respect to the direction of tension and one thus produces a certain wedge effect at the defect of the overlap *
The strip or profiled insert of thermoplastic synthetic material according to the present invention avoids the drawbacks which arise in known welding processes. The profiled strip of thermoplastic synthetic material according to the present invention for connecting two covered fabric sheets is shaped in such a way that it completely surrounds the edges of the two sheets which are to be connected together * and is welded on both sides. thermoplastic coverings.
In this way, the sizing of the weld joint
<Desc / Clms Page number 3>
so that the welded places present the same resistance as the sheet of fabric, is greatly facilitated. In addition, by using an applique whose section is that of a narrow H;, high, in the shape of a capital H, the edges of the textile sheet are surrounded by the arms of the H which grip on the two sides, and in this way it also avoids the torque in the seam joint which would facilitate breakage. Of course, other shapes of the section are also possible. Thus, the synthetic material strip may have, for example, a Z or S shape, as well as the shape of a 3 or a U.
While in many cases it is customary to manufacture the internal and external% covering layer of a textile sheet from different materials according to the conditions imposed on the finished product, the two materials used not being able to be touched together without taking measures. special, a lap weld is extraordinarily difficult. For this reason, gluing is most often used in practice.
According to the present invention, welding is made possible here too, in particular by the fact that the strip of synthetic material is formed in two parts .. which each consist of the covering material and they are glued to one another. in the middle or by devices known in sci, for example dovetail, in a manner analogous to that of a push button. When it is possible to weld the two different Layer% to each other, it is of course possible to weld the two halves of the strip. The length of the parts or tabs which surround the edges of the textile strip is advantageously 43 to 15 times the thickness of the textile sheet.
In many cases, for example for tanks $
<Desc / Clms Page number 4>
floating, it may be necessary to use strips or appliques of synthetic material which are luminescent, This can be obtained in a simple way by incorporating luminescent materials in the injection mass,
For the mechanical assembly of the sheets it is advantageous to use as much as possible transparent or translucent appliques, because then we can easily monitor the insertion of the edges to the bottom. The strip can be formed of 2 halves ,
assembled together with spring or clicks
The thermoplastic synthetic tape according to the invention will now be explained more closely with reference to the accompanying drawings which show various modes. realization,
In these drawings, Figures 1 and 4 show simple shapes of the H-shaped plastic strip,
Figures 2 and 3 show two shapes having a section other than the H section.
Figure 5 shows a strip formed by two joined strips! and. figure 6 shows a glued or welded form consisting of several parts
The H-shaped synthetic material strip according to Figures 1 and 4 consists of a middle part 1; 17 and sliders 2,3; 18,19, forming the notch which must receive the sheets of synthetic material to be welded.
The sheets 4; 5 of synthetic material reinforced by the textile sheets 6; 7 are introduced into the forced slots between the strips and are welded, using methods known per se,
<Desc / Clms Page number 5>
This can be done, for example, at the places shown in the dotted line drawings, but can also have the entire contact surface.
As can be seen from Figures 2 and 3, the synthetic material strip according to the present invention can have any suitable section. to the needs of the moment. Figure 2 shows a section in the form of 2 in which the middle strip located between the two synthetic material stirrers is connected by means of the elements 11 and 12 with the strips 9 and 10. In figure 3 a strip has been illustrated. h section in 3 in which the back 13 has three strips 14, 15 and 16.
In cases where two different materials have to be used for the covering of the textile sheet * it may be advantageous to constitute the strip of synthetic material from the same materials. According to the present invention there are two preferential possibilities for this which are illustrated in figures 5 and 6. The synthetic material strip according to figure 5 consists of a lower part 20, 23 with the slat 21 projecting from the middle part 20, and the upper part 22, 24 with the indentations 25 present in the middle part 22 and corresponding to the slats 21.
After which - possibly by a slight deformation of the upper part - the two parts of the synthetic material strip have been assembled * the two synthetic material sheets consisting of two different synthetic material layers 26 are introduced and 27, as well as soldering.
Another possibility for forming a strip of two different materials is shown in figure 6. The strip
<Desc / Clms Page number 6>
made of synthetic material consists of parts 28, 29, 30, and 31, where 26, 28 and 30, or 27, 29 and 31 are respectively made of a synthetic material of the same nature. The parts 30, 31 then 28 with 30 and 29 with 31 are first assembled by gluing or welding. Then the work is done in the same way as in the other forms described,
