Abstract

The device (3) has a chamber (4) filled with an adhesive. A fiber tail pipe (5) guides a reel (2), where length of the pipe is 2.5 cm and internal diameter of the pipe is 0.40 mm. An extrusion machine comprises an adhesive supply (6) continuously supplying the chamber. An optical fiber transmission (1) is rolled up in a layer presenting spaced adjacent whorls, where a space between the adjacent whorls is filled with the adhesive. An independent claim is also included for a method for winding an optical fiber transmission on a reel.

Description

DISPOSITIF D'ENDUCTION DE COLLE SUR UNE FIBRE DE TRANSMISSION OPTIQUE L'invention concerne un dispositif d'enduction de colle sur une 5 fibre de transmission optique et un procédé d'enroulement d'une fibre de transmission optique sur une bobine au moyen de ce dispositif. Il est recherché un procédé d'enroulement qui permette un déploiement libre de la fibre optique, sans perturbations mécaniques de type création de noeud ou équivalent et également sans perturbations 10 de transmission du signal traversant la fibre optique. Il est connu d'enduire en continu la fibre de colle lors de son bobinage au moyen d'un réservoir rempli de colle liquide et présentant deux orifices en vis-à-vis par lesquels passe la fibre horizontalement. La fibre traverse donc le réservoir de colle, avant d'être enroulée sur la 15 bobine. Si une telle enduction permet un bon maintien de la fibre, elle n'assure pas un dépôt régulier de la colle qui permette son dévidage et son déploiement régulier, des performances de transmission optiques fiables et une bonne stabilité quant à l'influence de la température. 20 Pour résoudre ce problème, l'invention propose un dispositif d'enduction en continu de colle sur une fibre optique destiné à être enroulée sur une bobine, comportant une chambre remplie de ladite colle, caractérisé en ce qu'il comporte une buse de sortie de la fibre destinée à assurer son guidage à proximité de ladite bobine. 25 Grâce à cette buse, le dispositif peut être disposé à proximité de la bobine lors du bobinage de la fibre. En effet, il est important que le bobinage soit effectué avec précision afin d'assurer un dévidage correct et que la quantité de colle appliqué autour de la fibre soit la plus constante possible. 30 Selon un mode de réalisation préféré, le dispositif est constitué d'une extrudeuse et comporte une alimentation continue en colle de ladite chambre. Le renouvellement de la colle est ainsi effectué automatiquement.The invention relates to a device for coating glue on an optical transmission fiber and a method for winding an optical transmission fiber on a coil by means of this method. device. It is desired a winding method that allows a free deployment of the optical fiber, without mechanical disturbances of the node-creating type or equivalent and also without disturbances 10 of transmission of the signal passing through the optical fiber. It is known to continuously coat the glue fiber during its winding by means of a reservoir filled with liquid glue and having two orifices vis-à-vis through which the fiber passes horizontally. The fiber thus passes through the glue reservoir, before being wound on the spool. If such a coating allows a good maintenance of the fiber, it does not ensure a regular deposit of the glue that allows its unwinding and regular deployment, reliable optical transmission performance and good stability in the influence of temperature . To solve this problem, the invention proposes a device for continuously coating adhesive on an optical fiber intended to be wound on a coil, comprising a chamber filled with said adhesive, characterized in that it comprises an outlet nozzle. fiber for guiding near said coil. Thanks to this nozzle, the device can be placed near the coil during the winding of the fiber. Indeed, it is important that the winding is carried out accurately to ensure proper unwinding and that the amount of glue applied around the fiber is as constant as possible. According to a preferred embodiment, the device consists of an extruder and comprises a continuous supply of glue from said chamber. The renewal of the glue is thus performed automatically.

Par ailleurs, il est possible de régler parfaitement le débit de colle qui doit être régulier, l'objectif étant que l'espace entre spires adjacentes soit rempli de colle. Ladite buse est de préférence d'une longueur d'environ 2,5 cm. L'invention concerne également un procédé d'enroulement d'une 10 fibre de transmission optique sur une bobine au moyen d'un dispositif d'enduction tel que précisé ci-dessus, caractérisé en ce que ladite fibre est enroulée en plusieurs couches présentant des spires adjacentes espacées d'une distance non nulle inférieure à deux diamètres de la fibre, l'espace entre spires adjacentes étant rempli de colle 15 L'invention est décrite ci-après plus en détail à l'aide d'une figure ne représentant qu'un mode de réalisation préféré de l'invention. La figure unique est une vue en coupe d'un dispositif d'enduction, selon l'invention. Selon l'invention, telle que représentée sur la figure 1, le procédé 20 de bobinage d'une fibre de transmission optique 1, d'un diamètre de l'ordre de 0,25 mm, sur une bobine 2 comprend le bobinage de plusieurs couches présentant des spires adjacentes espacées d'une distance non nulle inférieure à deux diamètres de la fibre, l'espace entre spires adjacentes étant rempli de colle. 25 La fibre 1 est enduite de colle en continu lors de son bobinage, grâce au dispositif conforme à l'invention. Ce dispositif d'enduction 3 en continu de colle sur la fibre optique 1 comporte une chambre 4 remplie de la colle et une buse de sortie 5 de la fibre, destinée à assurer son guidage à proximité de la 30 bobine.Moreover, it is possible to perfectly adjust the glue flow rate which must be regular, the objective being that the space between adjacent turns is filled with glue. Said nozzle is preferably of a length of about 2.5 cm. The invention also relates to a method of winding an optical transmission fiber on a coil by means of a coating device as specified above, characterized in that said fiber is wound in several layers with Adjacent turns spaced by a non-zero distance of less than two diameters of the fiber, the gap between adjacent turns being filled with glue The invention is hereinafter described in more detail with the help of a figure representing only a preferred embodiment of the invention. The single figure is a sectional view of a coating device according to the invention. According to the invention, as represented in FIG. 1, the method of winding an optical transmission fiber 1, with a diameter of the order of 0.25 mm, on a coil 2 comprises the winding of several layers having adjacent turns spaced at a non-zero distance of less than two diameters of the fiber, the gap between adjacent turns being filled with glue. The fiber 1 is coated with glue continuously during its winding, thanks to the device according to the invention. This coating device 3 continuous glue on the optical fiber 1 comprises a chamber 4 filled with glue and an outlet nozzle 5 of the fiber, intended to ensure its guidance near the coil.
