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

elastic band adhéslve easily déchlrable.

The invention relates to strips of which some chain son are elastic, one of the strip surfaces being coated with an adhesive material. This type of band is for example used for the immobilization of a joint.

The problem is solved by the invention is to allow the user to apply the strip without requiring the use of sharp instruments like scissors to cut the tape.

Joints immobilization techniques require the part of the practitioner, great dexterity, since the bandage to realize the asset should be cut frequently. Generally, the elastic adhesive tape is applied in difficult conditions. It therefore appears important to bring the practitioner the ability to use the web, without using a cutting tool, allowing him total availability for laying a significant time savings and total autonomy.

To date, the only adhesive strips existing tearable, consist of products such plasters. However, this type of product is totally different from an adhesive tape, in terms of its function, as its structure, since this material is not elastic. These include for example, GB patent teaching

2089820 which proposes to impregnate the textile substrate prior to coating of the adhesive, a primer whose function is to stiffen the support, giving it a certain resistance to facilitate its tearing. It therefore appears necessary to submit the tape to an additional operation. This problem can easily tear tape is even more important if the band presents channel based, elastic son. Indeed, if one tries to tear a textile backing comprising elastic son chain, it is found that the first son tend to come together against one another, forming a kind of string, thereby increasing their resistance.

This prior art can be illustrated by the teaching of patent WO 85/01660 which discloses an adhesive tape having elastic properties imparted by the presence of woven stretch son. As regards tearability of this band, and in view of the problems associated with the presence of elastic son as indicated above, it is necessary to use a fluid medium which is poured on the tape, to facilitate the manual tearing, under the effect of stiffening produced by the fluid medium.

It therefore appears that the incorporation of a stiffening agent is essential to allow manual tearing of the tape. In other words, in the absence of such an agent, the texture of the tape does not tear his textbook, in satisfactory condition and actually usable.

In those circumstances, the problem to be solved by the invention is to achieve an adhesive elastic band configured to be torn transversely by hand, without cutting tool, thereby facilitating its installation.

The introduction of elastic son. chain, in the base fabric, therefore requires special technical selection and arrangement of the son, to transversely tear the tape, without being obliged to use a stiffening agent. According to the invention, the adhesive elastic band is performed so that the base fabric not coated or adapted to be torn, more or less easy.

The subsequent application of the adhesive composition improves the tearability. It is therefore necessary to apply the adhesive composition, a specific way in order to improve the cohesion of the textile component son support.

The warp son are selected to spare between them sufficient space, enabling easy tear notch, while avoiding the gathering of channel son.

To solve the problem can easily rip the band directly by hand, the warp son are either small number compared to the weft son, or smaller diameter weft son to weaken the chain accordingly to stiffen the frame.

The tearability is finally obtained by applying an adhesive of any kind whatsoever. The coating is effected on one face of the textile support in order to increase cohesion and bond the warp son between them, preventing their sliding and removal at the time of tearing the strip. The adhesive may for example be applied homogeneously over the entire fabric surface.

The son being fixed together by the adhesive composition, it is possible to tear easily by hand, the tape.

The invention is described hereinafter in more detail using the appended drawings, in which: Figure 1 is a perspective view showing the tear by hand, of an elastic and adhesive support bandage.

Figure 2 is a plan view in schematic and large-scale, showing an embodiment of an elastic adhesive strip with tearing capacity according to the characteristics of the invention.

Figure 3 is a cross-sectional view taken along line 3.3 of Figure 2.

In a perfectly known manner, the adhesive tape according to the invention results from a chain interleaving son (1) and weft son (2). warp son (1) are performed in any well known material for one skilled in the art, such as elastane, to impart to the strip, elongation properties and stretchability, to realize a so-called elastic band.

According to the invention, the texture of the strip and / or the choice of chain son (1) and / or weft threads (2) are determined and selected to be struck between the warp son (1), a space or gap sufficient (E) in order to avoid the son (1) to come together when the strip is subjected to a transverse tensile load corresponding to its manual tearing

(figure 1). To facilitate the manual tearing of the band, it has become necessary to reduce the number of warp son (1) or to reduce their diameter. In these circumstances, to compensate for this decline in the chain, it is necessary either to increase the number of weft son, or use raster son (2) of a larger diameter, to give to the strip sufficient rigidity. It therefore appears that to weaken the chain and to stiffen the frame allows to rip the band relatively easily, without having to use a stiffening agent.

One face of this strip receives by coating or any other method, an adhesive material layer (3), which has the effect of considerably improving the tearability. Indeed, the space (E) lined with adhesive material (3), used to link the chain son (1) therebetween, avoiding them, as shown, to come together and, therefore, created a section overall making it impossible to manually tear the tape.

The adhesive material (3) is of the type generally used for an adhesive tape. These include, for example, acrylic adhesives, aqueous or solvating solutions, rubber or acrylic ...

The advantages are apparent from the description, in particular, emphasized and recalled the ability to manually and easily tear the tape, despite the incorporation into the texture of that son of elastic string, without being forced to the previously impregnated with a stiffening agent.

Claims

-1- elastic band resulting from interleaving son of elastic and non-elastic warp (1) and weft son (2), characterized in that the warp son (1) are selected for household, among them, a sufficient space (E), thus allowing an easy tear initiator while avoiding the gathering chain son.
-2- strip according to claim 1, characterized in that an adhesive material (3) is applied so as to cover almost the entire width of the web to bond the warp son, in particular by filling the space (E ).
-3- strip according to claim 1, characterized in that the warp son (1) are reduced in number relative to the weft son (2).
-4- strip according to claim 1, characterized in that the chain son (1) are of smaller diameter than the diameter of the weft son (2).
