Abstract
Description
L'invention concerne plus particulièrement les bandes de contention adhésive et cohésive et plus généralement tout type de bande ayant des capacités d'adhérence. Ces bandes après avoir été découpées, par tous moyens connus et appropriés, en différents lés, sont conditionnées en rouleau.The invention relates more particularly to adhesive and cohesive compression bands and more generally to any type of band having adhesion capacities. These strips after having been cut, by any known and appropriate means, into different strips, are packaged in a roll.
De telles bandes sont enroulées sous tension sur un tube qui fait office de mandrin, ce qui engendre certains inconvénients. Outre le fait que le mandrin augmente le coût de la bande, il apparaît une certaine difficulté pour dérouler manuellement la bande au niveau dudit mandrin. En effet, au fur et à mesure du déroulement de la bande, son diamètre diminue, de sorte que le couple de déroulement exercé tend également à diminuer.Such strips are wound under tension on a tube which acts as a mandrel, which gives rise to certain drawbacks. In addition to the fact that the mandrel increases the cost of the strip, there appears to be a certain difficulty in manually unwinding the strip at the level of said mandrel. Indeed, as the strip unfolds, its diameter decreases, so that the unwinding torque exerted also tends to decrease.
Par ailleurs, au début de l'enroulement, la tension est plus forte, de sorte que sous l'effet de la masse adhésive, les parties en contact de la bande sont étroitement et fortement liées les unes aux autres, ce qui tend, encore, à rendre difficile le déroulement de la bande à ce niveau.Furthermore, at the start of the winding, the tension is higher, so that under the effect of the adhesive mass, the parts in contact with the strip are closely and strongly bonded to each other, which tends, again , to make it difficult for the tape to unfold at this level.
L'invention s'est fixée pour but de remédier à ces inconvénients, d'une manière simple, efficace et rationnelle.The object of the invention is to remedy these drawbacks in a simple, efficient and rational manner.
Plus particulièrement, l'invention se propose de résoudre simultanément le double problème, d'une part, de supprimer le mandrin d'enroulement et d'autre part, de pouvoir dérouler en totalité la bande sans difficulté particulière.More particularly, the invention proposes to simultaneously solve the double problem, on the one hand, of eliminating the winding mandrel and on the other hand, of being able to unroll the entire strip without particular difficulty.
Pour résoudre, d'une manière satisfaisante, chacun des problèmes posés, il en résulte un procédé particulier pour enrouler la bande. Selon l'invention, le procédé est remarquable par les étapes suivantes :To solve each of the problems satisfactorily, this results in a particular method for winding the strip. According to the invention, the process is remarkable by the following stages:
On saisit l'une des extrémités de la bande ; on rabat cette extrémité saisie pour l'appliquer en superposition sur ladite bande, selon une certaine longueur ; on enroule la bande à partir de cette extrémité rabattue.We grab one end of the strip; this captured end is folded down to apply it superimposed on said strip, along a certain length; we roll it up strip from this folded end.
L'extrémité de la bande est rabattue en superposition sur très sensiblement une longueur de 20 à 30 cm.The end of the strip is folded in superposition over a very substantial length of 20 to 30 cm.
D'une manière avantageuse, il apparaît que la bande enroulée, dans les conditions du procédé, ne présente pas de mandrin d'enroulement.Advantageously, it appears that the wound strip, under the process conditions, does not have a winding mandrel.
Le procédé peut être mis en oeuvre par tout moyen connu et approprié, automatique ou semi-automatique, en étant aptes à traiter simultanément une ou plusieurs bandes.The method can be implemented by any known and appropriate means, automatic or semi-automatic, while being capable of simultaneously processing one or more strips.
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 d'une bande enroulée sur un mandrin selon l'état antérieur de la technique.
- Les figures 2 à 5 sont des vues en perspective montrant les principales phases du procédé.
- La figure 6 est une vue en perspective de la bande selon l'invention.
- La figure 7 est une vue en coupe montrant schématiquement le principe du déroulement arrivé en fin de bande.
- Figure 1 is a perspective view of a strip wound on a mandrel according to the prior art.
- Figures 2 to 5 are perspective views showing the main phases of the process.
- Figure 6 is a perspective view of the strip according to the invention.
- Figure 7 is a sectional view schematically showing the principle of the unwinding at the end of the strip.
Comme indiqué, l'invention s'applique plus particulièrement à tous types de bande élastique adhésive ou cohésive, notamment pour la contention. D'une manière parfaitement connue, de telles bandes sont généralement exécutées en grande largeur et traitées pour âtre adhésives, puis découpées en lés (1) (figure 1).As indicated, the invention applies more particularly to all types of adhesive or cohesive elastic band, in particular for compression. In a perfectly known manner, such strips are generally executed in great width and treated for adhesive hearths, then cut into strips (1) (Figure 1).
Selon l'invention, pour enrouler la bande (1), on procède de la manière suivante :
- on saisit l'une des extrémités (1a) de la bande (figure 2) ;
- on rabat l'extrémité saisie (1a), pour l'appliquer en superposition sur la partie correspondante (1b) de la bande (figure 3), selon une certaine longueur ;
- à partir de cette extrémité rabattue et superposée (1a - 1b) , on procède à l'enroulement de la bande (figure 4) par tout moyen connu et approprié.According to the invention, to wind the strip (1), the procedure is as follows:
- one grasps one of the ends (1a) of the strip (FIG. 2);
- The gripped end is folded down (1a), to apply it superimposed on the corresponding part (1b) of the strip (Figure 3), along a certain length;
- from this folded over and superimposed end (1a - 1b), the strip is wound up (Figure 4) by any known and appropriate means.
Il est bien évident que les différentes étapes susindiquées peuvent être mécanisées par différents moyens pour automatiser le procédé selon l'invention. De tels moyens de mise en oeuvre ne sont pas décrits, car ils sont à la portée de tout homme de métier et peuvent faire l'objet de différentes variantes d'exécution.It is obvious that the various steps mentioned above can be mechanized by different means to automate the process according to the invention. Such means of implementation are not described, because they are within the reach of any person skilled in the art and can be the subject of different variant embodiments.
A titre indicatif, l'extrémité (1b) de la bande est rabattue sur une longueur de très sensiblement 20 à 30 centimètres.As an indication, the end (1b) of the strip is folded over a length of very substantially 20 to 30 centimeters.
Compte tenu des caractéristiques spécifiques d'enroulement, il en résulte, d'une manière particulièrement importante et avantageuse, d'une part, la suppression du mandrin et, d'autre part, une facilité d'utilisation de la bande qui peut être très facilement déroulée jusqu'à son extrémité finale. En effet, après avoir déroulée la bande, lorsque l'utilisateur arrive au niveau de l'extrémité (1a), il suffit qu'il saisisse manuellement cette extrémité pour l'écarter angulairement de la partie correspondante (1b) de la bande (figure 6). Cette opération peut s'effectuer sans difficulté compte tenu de l'effort que peut exercer l'utilisateur résultant du positionnement des parties (1a - 1b).Taking into account the specific winding characteristics, this results, in a particularly important and advantageous manner, on the one hand, the elimination of the mandrel and, on the other hand, an ease of use of the strip which can be very easily unwound to its final end. Indeed, after having unrolled the strip, when the user arrives at the end (1a), it suffices that he manually grasps this end to move it angularly away from the corresponding part (1b) of the strip (figure 6). This operation can be carried out without difficulty taking into account the effort which the user can exert resulting from the positioning of the parts (1a - 1b).
A noter que l'une des faces au moins de la bande peut présenter à proximité du bord transversal de l'extrémité (1a), tout moyen d'indication visuel (1c) pour permettre à l'utilisateur de repérer facilement et rapidement les parties d'extrémités superposées (1a-1b), au moment de la mise en place de la bande, en fin de déroulement. Par exemple, ce moyen d'indication visuel peut être réalisé par une marque de couleur diférente de celle du reste de la bande.Note that at least one of the faces of the strip may have, near the transverse edge of the end (1a), any means of visual indication (1c) to allow the user to easily and quickly locate the parts superimposed ends (1a-1b), when the strip is put in place, at the end of the unwinding. For example, this visual indication means can be produced by a mark of color different from that of the rest of the strip.
Les avantages ressortent bien de la description. En particulier, on souligne que la bande de contention, cohésive ou adhésive, est conditionnée en rouleau sans l'emploi de mandrin en étant très aisément déroulable en vue de son utilisation, jusqu'à son extrémité finale.The advantages are apparent from the description. In particular, it is emphasized that the compression band, cohesive or adhesive, is packaged in a roll without the use of a mandrel, being very easily unrollable for its use, until its final end.
