Abstract

The subject of the invention relates to a sail for nautical craft, gliders and the like. It consists of the coating of the fabric by a lamination whose thickness varies between 5 and 50 microns. This lamination being obtained by an extrusion, adhesive bonding or calandering which makes a film of polypropylene adhere to the weft and warp weave, the coating being preferably of the same nature as the support. It is intended to equip sailboards, boats, gliders and the like with a floating, waterproof, light, flexible and elastic element.

Description

L'objet de l'invention concerne une voilure pour engins nautiques, planeurs et similaires. The object of the invention relates to a wing for nautical machines, gliders and the like.

11 est destiné à équiper les planches à voile, bateaux planeurs et similaires avec un élément flottant, imperméable, léger, souple et élastique. 11 is intended to equip windsurfers, gliding boats and the like with a floating, waterproof, light, flexible and elastic element.

Les voilures utilisées à ce jour pour engins nautiques voiliers et autres sont obtenues en fibres polyester dont a densité est supérieure à 1 et sont toutes immergeables. Cet état de chose présente de nombreux inconvénients pour les usagers, plus particulièrement en ce qui concerne les voiliers et les planches à voile, car leur relèvement après immersion est rendu plus difficile et pénible. De plus, en cas d'arrachement la voile est immergée, ce qui rend sa récupération parfois impossible. The sails used to date for nautical sailing ships and others are obtained from polyester fibers whose density is greater than 1 and are all submersible. This state of affairs has many disadvantages for users, more particularly with regard to sailboats and windsurfers, because their recovery after immersion is made more difficult and painful. In addition, in the event of tearing off the sail is submerged, which makes it sometimes impossible to recover.

Le produit obtenu suivant l'invention supprime ces inconvénients et permet la réalisation d ' un tissu souple et élastique, imperméable à l'air, à l'eau et à tous fluides ayant une densité inférieur à 1, c'est-à-dire donnant la possibilité à une voile de flotter en quelle condition que ce soit. The product obtained according to the invention eliminates these drawbacks and allows the production of a flexible and elastic fabric, impermeable to air, to water and to all fluids having a density less than 1, that is to say giving the possibility to a sail to float in any condition.

II est constitué par le revetement du tissu par un laminage dont l'épaisseur varie entre 5 et 50 microns. Ce laminage étant obtenu par extrusion, collage ou calandrage faisant adhérer au tissage trame et channe un film de polypropylène, 1 'enduction étant préférentiellement de meme nature que le support. It consists of the coating of the fabric by rolling, the thickness of which varies between 5 and 50 microns. This lamination is obtained by extrusion, gluing or calendering making the weft weave adhere to a polypropylene film, the coating preferably being of the same nature as the support.

Suivant un mode de fabrication donné à titre d ' exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention, on procède de la façon suivante
On utilise un tissu en fibres synthétiques qu'on revêt d'un laiidiinage d'une épaisseur variant entre 5 et 50 microns sur chacune de ses faces.According to a manufacturing mode given by way of nonlimiting example, of one of the embodiments of the object of the invention, the procedure is as follows
A synthetic fiber fabric is used which is coated with a fabric having a thickness varying between 5 and 50 microns on each of its faces.

Le laminage est obtenu par extrusion, par collage ou calandrage, de façon qutil adhère au tissu afin de bloquer les fils dans le sens channe et trame et à le rendre imperméable.  The lamination is obtained by extrusion, by gluing or calendering, so that it adheres to the fabric in order to block the threads in the warp and weft direction and to make it waterproof.

Ce tissu est lui-même en fibres de polypropylène pour le tissage, et une enduction en polypropylène liquide à chaud sur une ou deux de ses faces permet d'obtenir une parfaite cohésion par intégration moléculaire parfaite. This fabric is itself made of polypropylene fibers for weaving, and a coating of hot liquid polypropylene on one or two of its faces makes it possible to obtain perfect cohesion by perfect molecular integration.

Ce tissu est enduit à chaud. C'est donc bien par l'application sur les fils de chaîne et de trame d'un enduit de 5 à 50 microns de polypropylène qui s'intégre au tissu aussi bien mécaniquement que par effet de tension superficielle. This fabric is hot coated. It is therefore good by applying to the warp and weft threads a coating of 5 to 50 microns of polypropylene which integrates into the fabric both mechanically and by the effect of surface tension.

On obtient ainsi un tissu léger, flottant et imper méable quoique extremement résistant par sa texture armée, souple et élastique. A light, floating and waterproof fabric is obtained, although extremely resistant by its reinforced, flexible and elastic texture.

Le -procédé d'enduction peut varier, c'est ainsi qu'on peut utiliser la pulvérisation fractionnée ou l'atomisation pour le répandage du film sur les fibres formant des infractuosités d'ancrage réceptrices.  The coating process may vary, thus it is possible to use fractional spraying or atomization for spreading the film on the fibers forming receptive anchoring infructuosities.
