Abstract

An elastic bandage produced by weaving together elastic and inelastic warp yarns (1) and weft yarns (2), and remarkable in that the warp yarns (1) are selected in such a way that sufficient space (E) is left therebetween to enable an incipient tear to be achieved easily while preventing bunching of said warp yarns.

Description

Bande élastique adhéslve facilement déchlrable. Easily tear-off adhesive elastic band.
L'invention concerne les bandes dont certains fils de chaîne sont élastiques, l'une des faces de la bande étant recouverte d'une matière adhésive. Ce type de bande est par exemple utilisé pour l'immobilisation d'une articulation.The invention relates to bands of which certain warp threads are elastic, one of the faces of the band being covered with an adhesive material. This type of band is for example used for immobilizing a joint.
Le problème que se propose de résoudre l'invention est de permettre à l'utilisateur, d'appliquer la bande sans nécessiter l'emploi d'instruments tranchants du type ciseaux, pour couper la bande.The problem which the invention proposes to solve is to allow the user to apply the strip without requiring the use of sharp instruments of the scissor type, for cutting the strip.
Les techniques d'immobilisation des articulations nécessitent, de la part du praticien, une grande dextérité, étant donné que le bandage, pour réaliser l'immobilisation, doit être coupé fréquemment. D'une manière générale, la bande élastique adhésive est appliquée dans des conditions délicates. Il apparait donc important d'apporter au praticien, la possibilité d'utiliser la bande, sans avoir recours à un outil tranchant, lui permettant ainsi une disponibilité totale pour la pose, un gain de temps appréciable et une autonomie totale.Joint immobilization techniques require great dexterity on the part of the practitioner, since the bandage, to achieve immobilization, must be cut frequently. In general, the adhesive elastic band is applied under delicate conditions. It therefore appears important to provide the practitioner with the possibility of using the strip, without having to use a sharp tool, thus allowing him total availability for installation, appreciable time savings and total autonomy.
A ce jour, les seules bandes adhésives déchirables existantes, sont constituées par des produits du type sparadraps. Toutefois, ce type de produit est totalement différent d'une bande adhésive, tant au niveau de sa fonction, que de sa structure, étant donné que ce produit est non élastique. On peut citer par exemple, l'enseignement du brevet FRTo date, the only tear-off adhesive strips existing, are constituted by products of the adhesive plaster type. However, this type of product is completely different from an adhesive tape, both in terms of its function and its structure, since this product is non-elastic. We can cite for example, the teaching of the FR patent
2089820 qui propose d'imprégner le support textile avant l'enduction de la matière adhésive, d'un apprêt dont la fonction est de rigidifier ce support en lui donnant une certaine résistance pour faciliter son déchirement. Il apparait donc nécessaire de soumettre la bande à une opération supplémentaire. Ce problème de pouvoir facilement déchirer une bande est encore plus important dans le cas où la bande présente en chaîne notamment, des fils élastiques. En effet, si l'on essaye de déchirer un support textile comportant des fils élastiques en chaîne, on constate que les premiers fils ont tendance à se rassembler les uns contre les autres, formant une sorte de ficelle, augmentant ainsi leur résistance.2089820 which proposes to impregnate the textile support before coating the adhesive material, with a finish the function of which is to stiffen this support by giving it a certain resistance to facilitate its tearing. It therefore appears necessary to subject the strip to an additional operation. This problem of being able to easily tear a strip is even more important in the case where the strip has in particular a chain, elastic threads. Indeed, if we try to tear a textile support comprising elastic warp threads, we see that the first threads tend to come together against each other, forming a kind of string, thus increasing their resistance.
Cet état de la technique peut être illustré par l'enseignement du brevet WO 85/01660 qui divulgue une bande adhésive présentant des propriétés élastiques conférées par la présence de fils extensibles tissés. En ce qui concerne la déchirabilité de cette bande, et compte-tenu des problèmes liés à la présence des fils élastiques comme indiqué précédemment, il est nécessaire d'utiliser un agent fluide qui est répandu sur la bande, afin de faciliter le déchirement manuel, sous l'effet du raidissement produit par l'agent fluide.This state of the art can be illustrated by the teaching of patent WO 85/01660 which discloses an adhesive strip having elastic properties imparted by the presence of woven stretch yarns. With regard to the tearability of this strip, and taking into account the problems linked to the presence of the elastic threads as indicated previously, it is necessary to use a fluid agent which is spread over the strip, in order to facilitate manual tearing, under the effect of the stiffening produced by the fluid agent.
Il apparait donc que l'incorporation d'un agent raidisseur est indispensable pour permettre le déchirement manuel de la bande. Autrement dit, en l'absence d'un tel agent, la contexture de la bande ne permet pas son déchirement manuel, dans des conditions satisfaisantes et réellement utilisables.It therefore appears that the incorporation of a stiffening agent is essential to allow manual tearing of the strip. In other words, in the absence of such an agent, the texture of the strip does not allow its manual tearing, under satisfactory conditions and actually usable.
Dans ces conditions, le problème que se propose de résoudre l'invention, est de réaliser une bande élastique adhésive, conformée pour être déchirée transversalement à la main, sans outil de coupe, permettant ainsi de faciliter sa pose.Under these conditions, the problem which the invention proposes to solve is to produce an adhesive elastic band, shaped to be torn transversely by hand, without a cutting tool, thus making it easier to install.
L'introduction de fils élastiques. en chaîne, dans le support textile, nécessite donc une technique particulière de sélection et de disposition des fils, afin de pouvoir déchirer transversalement la bande, sans être obligé d'utiliser un agent raidisseur. Selon l'invention, la bande élastique adhésive est réalisée de sorte que le support textile non enduit, soit apte à être déchiré, de façon plus ou moins facile.The introduction of elastic threads. in warp, in the textile support, therefore requires a particular technique of selection and arrangement of the threads, in order to be able to tear the strip transversely, without being obliged to use a stiffening agent. According to the invention, the adhesive elastic band is produced so that the uncoated textile support is able to be torn, more or less easily.
L'application ultérieure de la masse adhésive permet d'améliorer la déchirabilité. Il est donc nécessaire d'appliquer la masse adhésive, d'une manière déterminée, afin d'améliorer la cohésion des fils composant le support textile.The subsequent application of the adhesive mass makes it possible to improve the tearability. It is therefore necessary to apply the adhesive mass, in a determined manner, in order to improve the cohesion of the threads composing the textile support.
Les fils de chaîne sont sélectionnés pour ménager, entre eux, un espace suffisant, permettant ainsi une amorce de déchirure aisée, tout en évitant le rassemblement des fils de chaîne.The warp threads are selected to provide sufficient space between them, thus allowing an easy tear to start, while avoiding the gathering of warp threads.
Pour résoudre le problème posé de pouvoir déchirer facilement la bande, directement à la main, les fils de chaîne sont soit en nombre réduit par rapport aux fils de trame, soit de diamètre inférieur au diamètre des fils de trame, afin de fragiliser la chaîne et de rigidifier en conséquence la trame.To solve the problem posed of being able to tear the strip easily, directly by hand, the warp threads are either in reduced number compared to the weft threads, or of diameter smaller than the diameter of the weft threads, in order to weaken the warp and to stiffen the frame accordingly.
La déchirabilité est définitivement obtenue par l'application d'une masse adhésive, de quelque nature que se soit. L'enduction s'effectue sur une face du support textile afin d'augmenter la cohésion et la liaison des fils de chaîne entre eux, évitant leur glissement et leur retrait au moment de déchirer la bande. La masse adhésive peut, par exemple être appliquée de façon homogène, sur toute la surface textile.The tear-off is definitively obtained by the application of an adhesive mass, of whatever kind. The coating is carried out on one side of the textile support in order to increase the cohesion and the connection of the warp threads with one another, avoiding their sliding and their withdrawal when tearing the strip. The adhesive mass can, for example, be applied homogeneously, over the entire textile surface.
Les fils étant immobilisés entre eux par la masse adhésive, il est possible de déchirer facilement à la main, la bande.The son being immobilized together by the adhesive mass, it is possible to easily tear by hand, the strip.
L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels : La figure 1 est une vue en perspective montrant le déchirement à la main, d'une bande de contention élastique et adhésive.The invention is set out below in more detail using the appended drawings, in which: Figure 1 is a perspective view showing the tearing by hand, of an elastic and adhesive bandage.
La figure 2 est une vue en plan à caractère schématique et à grande échelle, montrant un exemple de réalisation d'une bande adhésive élastique avec capacité de déchirement selon les caractéristiques de l'invention.Figure 2 is a schematic plan view on a large scale, showing an embodiment of an elastic adhesive strip with tearing capacity according to the features of the invention.
La figure 3 est une vue en coupe transversale considérée selon la ligne 3.3 de la figure 2.Figure 3 is a cross-sectional view taken along line 3.3 of Figure 2.
D'une manière parfaitement connue, la bande adhésive, selon l'invention, résulte d'un entrelacement de fils de chaîne (1) et de fils de trame (2). Les fils de chaîne (1) sont exécutés dans toute matière parfaitement connue pour un homme du métier, telle que l'élasthane, pour conférer à la bande, des propriétés d'allongement et d'extensibilité, afin de réaliser une bande dite élastique.In a perfectly known manner, the adhesive strip according to the invention results from an interlacing of warp threads (1) and weft threads (2). The warp threads (1) are made of any material perfectly known to a person skilled in the art, such as spandex, to give the strip, elongation and extensibility properties, in order to produce a so-called elastic strip.
Selon l'invention, la contexture de la bande et/ou le choix des fils de chaîne (1) et/ou de trame (2), sont déterminés et sélectionnés pour ménager entre les fils de chaîne (1), un espace ou écartement suffisant (E), afin d'éviter aux fils (1), de se rassembler lorsque la bande est soumise à un effort de traction transversal correspondant à son déchirement manuelAccording to the invention, the texture of the strip and / or the choice of warp (1) and / or weft (2) threads are determined and selected to provide a space or spacing between the warp threads (1) sufficient (E), in order to avoid the wires (1), coming together when the strip is subjected to a transverse tensile force corresponding to its manual tearing
(figure 1). Pour faciliter ce déchirement manuel de la bande, il est apparu nécessaire de réduire le nombre de fils de chaîne (1) ou de diminuer leur diamètre. Dans ces conditions, pour compenser cette diminution au niveau de la chaîne, il est nécessaire, soit d'augmenter le nombre de fils de trame, soit d'utiliser des fils de trame (2) d'un diamètre plus important, afin de donner à la bande une rigidité suffisante. Il apparait donc que le fait de fragiliser la chaîne et de rigidifier la trame permet de déchirer la bande relativement facilement, sans être obligé d'utiliser un agent raidisseur.(figure 1). To facilitate this manual tearing of the strip, it appeared necessary to reduce the number of warp threads (1) or to reduce their diameter. Under these conditions, to compensate for this reduction in the warp, it is necessary either to increase the number of weft threads, or to use weft threads (2) of a larger diameter, in order to give to the band sufficient rigidity. It therefore appears that the fact of weakening the chain and stiffening the weft makes it possible to tear the strip relatively easily, without being obliged to use a stiffening agent.
L'une des faces de cette bande reçoit par enduction ou tout autre procédé, une couche de matière adhésive (3), ce qui a pour effet de considérablement améliorer la déchirabilité. En effet, l'espace (E) garni de la matière adhésive (3), permet de lier les fils de chaîne (1) entre eux, en leur évitant, comme indiqué, de se rassembler et, par conséquent, de créer une section globale rendant impossible le déchirement manuel de la bande.One of the faces of this strip receives by coating or any other process, a layer of adhesive material (3), which has the effect of considerably improving the tearability. Indeed, the space (E) lined with the adhesive material (3), makes it possible to link the warp threads (1) together, avoiding them, as indicated, from gathering together and, consequently, from creating a section overall making manual tearing of the tape impossible.
La matière adhésive (3), est du type de celle généralement employée pour une bande adhésive. On peut citer par exemple, les colles acryliques, les solutions aqueuses ou solvantes, caoutchouc ou acrylique...The adhesive material (3) is of the type generally used for an adhesive strip. Mention may be made, for example, of acrylic adhesives, aqueous or solvent solutions, rubber or acrylic, etc.
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la possibilité de déchirer manuellement et facilement la bande adhésive, malgré l'incorporation dans la contexture de cette dernière de fils de chaîne élastiques, sans pour autant être obligé de l'imprégner préalablement d'un agent raidisseur. The advantages emerge clearly from the description, in particular the possibility of manually and easily tearing the adhesive strip is emphasized and recalled, despite the incorporation into the texture of the latter of elastic warp threads, without however being obliged to impregnate beforehand with a stiffening agent.
