D'autres caractéristiques ressortiroπt de la suite de la description .Other characteristics will emerge from the following description.
L'invention est exposée ci-après plus en détail à l'aide des dessins qui représentent seulement un mode d'exécu¬ tion :The invention is set out below in more detail using the drawings which represent only one mode of execution:
- la figure 1 est une vue à caractère purement sché¬ matique illustrant l'installation pour la mise en oeuvre du procéd , - la figure 2 est une vue en coupe transversale considérée selon la ligne 2.2. de la figure 1,- Figure 1 is a purely sché¬ matic view illustrating the installation for the implementation of the procedure, - Figure 2 is a cross-sectional view taken along line 2.2. of figure 1,
- les figures 3 et 4 sont, à grande échelle, des vues partielles en coupe longitudinale de la bande,FIGS. 3 and 4 are, on a large scale, partial views in longitudinal section of the strip,
- la figure 5 montre un échantillon d'un exemple de réalisation de la bande cohésive.- Figure 5 shows a sample of an exemplary embodiment of the cohesive tape.
Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative en se référant aux exemples de réalisation des figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.
La bande est obtenue a partir d'un tissu résultant de l'entrelacement des fils de chaîne (1) et des fils de trame (2) selon une armure donnée. Ce tissage peut être classique, c'est- à-dire entrelacement successif d'un fil de chaîne et d'un fil de trame (figure 3) ou bien ce tissage peut être exécuté sur un métier à crochet en réalisant un entrelacement successif d'un fil de chaîne (1) et de deux fils de trame (2) (figure 4). Plusieurs modes de tissage et de tricotage peuv être prévus quant à la nature des fils les composant, à savoThe strip is obtained from a fabric resulting from the interlacing of the warp threads (1) and the weft threads (2) according to a given weave. This weaving can be conventional, that is to say successive intertwining of a warp thread and a weft thread (Figure 3) or else this weaving can be performed on a hook loom by performing a successive intertwining d 'a warp thread (1) and two weft threads (2) (Figure 4). Several modes of weaving and knitting can be provided as to the nature of the yarns composing them, to savo
- chaîne composée de fils extensibles et trame fils non extensibles,- warp composed of stretchy threads and non-stretchable weft thread,
- chaîne et trame composées de fils extensibles,- warp and weft composed of stretchy threads,
- chaîne composée en alternance de fils extensib et inextensibles, trame en fils non extensibles,- warp composed alternately of extensible and inextensible yarns, weft of non-extensible yarns,
- chaîne composée en alternance de fils extensib et inextensibles, trame en fils extensibles.- warp composed alternately of extensible and inextensible yarns, weft of extensible son.
A titre d'exemple indicatif nullement limitatif, l fils composant le tissu, sont du coton, de la viscose et l'élasthane, dans les proportions suivantes :By way of nonlimiting example, the threads composing the fabric are cotton, viscose and elasthane, in the following proportions:
- coton : 21 %- cotton: 21%
- viscose : 78,2 %- viscose: 78.2%
- élasthane : 0,8 %- elastane: 0.8%
La figure 1 illustre un exemple d'installation pour la mise oeuvre du procédé.FIG. 1 illustrates an example of an installation for implementing the method.
Après tissage ou tricotage, la bande (B) est soumi à une rétraction préalable à la vapeur pour lui donner allongement compris entre 110 et 140 % . La bande est ensui conditionnée en rouleau.After weaving or knitting, the strip (B) is subjected to a prior steam shrinkage to give it elongation of between 110 and 140%. The strip is then packaged in a roll.
Le rouleau de conditionnement (R) de la bande e asservi à un organe de commande conformé pour assurer à ladi bande un déroulement positif correspondant à l'allongeme initial compris entre 110 et 140 % . A la sortie du rouleau conditionnement (R) , la bande (B) est soumise à un donne positif (D) pour lui conférer un allongement compris entre et 110 % . La bande est alors acheminée, au moyen d'un 'tap roulant (T) , dans une cabine de pulvérisation (C) pour soume tre l'une des faces seulement de la bande, à une projecti d'une emulsion aqueuse de gomme naturelle du type LATEX l quide,ou autre masse liquide adhesive de caoutchouc. A la sort de la cabine de pul érisation, la face é ulsionnée (Ba ) pas dans une cabine de séchage (S) puis est conditionnée sur rouleau de réception (RI) de sorte que ladite face émulsionné soit située du côté interne.The conditioning roller (R) of the strip is slaved to a shaped control member to ensure that the strip has a positive course corresponding to the initial elongation of between 110 and 140%. At the outlet of the conditioning roll (R), the strip (B) is subjected to a positive deal (D) to give it an elongation of between and 110%. The strip is then conveyed, by means of a rolling tap (T), in a spray booth (C) to support only one of the faces of the strip, to a spray of an aqueous emulsion of natural gum. LATEX type l quide, or other adhesive liquid rubber. At the end of the spray booth, the side (Ba) not in a drying booth (S) and then conditioned on receiving roller (RI) so that said emulsified face is located on the internal side.
Le rouleau de réception (Ri) est alors positionné su le mandrin support du rouleau de conditionnement asservi a donneur positif (D) , pour acheminer dans les conditions indi quées précédemment, la bande (B) dans la cabine de pulvérisa tion afin de soumettre l'autre face (Bb) à la projection d Latex, puis à l'opération de séchage. On obtient donc un pluralité de bouclettes de LATEX susceptibles de s'enchevêtre lorsque deux parties de la bande sont mises en contact et e pression en lui conférant ainsi le caractère cohésif recherchéThe receiving roller (Ri) is then positioned on the support mandrel of the conditioning roller controlled by a positive donor (D), to convey under the conditions indicated above, the strip (B) in the spray booth in order to subject the 'other side (Bb) to the Latex projection, then to the drying operation. We therefore obtain a plurality of LATEX loops capable of becoming entangled when two parts of the strip are brought into contact and under pressure, thereby giving it the desired cohesive character.
A noter que la cabine de pulvérisation met en oeuvr des moyens parfaitement connus et conformés pour assurer un répartition constante et uniforme de l'emulsion aqueuse d gomme naturelle sur chacune des faces de la bande.Note that the spray booth implements perfectly known and shaped means to ensure a constant and uniform distribution of the aqueous emulsion of natural gum on each side of the strip.
D'une manière préférée, cette pulvérisation s'effec tue au moyen de deux buses d'injection jointives (Ca) et (Cb) De même, étant donné que la bande, pour des raisons évidente d'économie, est traitée selon de grandes largeurs, les buse d'injection sont assujetties à un support pour être déplacée transversalement et alternativement selon toute la largeur d la bande, au fur et à mesure de son déplacement.Preferably, this spraying is carried out by means of two contiguous injection nozzles (Ca) and (Cb) Likewise, since the strip, for obvious reasons of economy, is treated according to large widths, the injection nozzles are subject to a support to be moved transversely and alternately along the entire width of the strip, as it moves.
A la sortie de l'installation, après les différent traitements et étapes , la bande cohésive obtenue a un allonge ment compris entre 70 et 90 % . Les lisières sont supprimée pour autoriser un déchirement transversal de la bande de faço manuelle, sans l'emploi d'un outil de coupe quelconque.At the exit of the installation, after the various treatments and stages, the cohesive strip obtained has an elongation between 70 and 90%. The selvedges are removed to allow a transverse tearing of the strip of manual manner, without the use of any cutting tool.
De plus, l'imprégnation ainsi obtenue par pulvérisa tion d'une emulsion aqueuse de gomme naturelle, facilite l déchirement manuel de la boucle. Il est entendu que le lé de l bande est découpé selon différentes largeurs correspondant au largeurs de bandes normalisées.In addition, the impregnation thus obtained by spraying with an aqueous emulsion of natural gum facilitates manual tearing of the loop. It is understood that the strip of the strip is cut according to different widths corresponding to the standard strip widths.
De même, pour assurer un meilleur accrochage du late sur la bande, on prévoit d'exécuter toutes les trames en coton On renvoie à la figure 5 des dessins qui montre u échantillon de la bande cohésive selon l'invention. Il est b évident que 1 ' aspect de cette bande peut être différent présenter un effet plus ou moins aéré en fonction de l'arm du tissage ou tricotage de base.Similarly, to ensure better adhesion of the late to the strip, it is planned to execute all the cotton wefts. Reference is made to FIG. 5 of the drawings which shows a sample of the cohesive strip according to the invention. It is obvious that the appearance of this strip may be different, presenting a more or less airy effect depending on the weaving or basic knitting fabric.
La bande de contention cohésive résultant du procé conserve ses qualités thérapeutiques et est particulièrem recommandée dans le domaine de la phlébologie et des traumati mes sportifs. The cohesive compression bandage resulting from the process retains its therapeutic qualities and is particularly recommended in the field of phlebology and sports injuries.
