<Desc/Clms Page number 1> <Desc / Clms Page number 1> L'invention concerne un dispositif pour l'envidage de fils, constitué par des cylindres entrainés qui peuvent être pressés contre des bobines ou tubes d'enroulement et entraîner ceux-ci en rotation. The invention relates to a device for unwinding son, consisting of driven cylinders which can be pressed against reels or winding tubes and drive them in rotation. Dans tous les tubes d'enroulement ou bobines de filage, entraînés par des cylindres de friction, il est pratiquement impossible de faire en sorte que, lors de l'application du fil, après le change- ment de bobines, le cylindre de friction et la bobine d'enroulement tournent à des vitesses périphériques absolument identiques. Dans le cas de tubes d'enroulement lisses et de cylindres de friction unis, tels qu'utilisés couramment, l'accélération du tube nouvellement mis en place donne lieu, jusqu'au moment où un synchronisme parfait des deux éléments est atteint, à un patinage relatif des aires latérales de ceux-ci, ce qui a pour effet de détériorer ou de déchirer le fil appliqué déterminant ainsi des perturbations dans,le bobinage. In all winding tubes or spinning coils, driven by friction rollers, it is practically impossible to ensure that, when applying the yarn, after changing the coils, the friction cylinder and the winding reel rotate at absolutely identical peripheral speeds. In the case of smooth winding tubes and united friction cylinders, as commonly used, the acceleration of the newly placed tube gives rise, until the moment when a perfect synchronism of the two elements is reached, in a relative slippage of the lateral areas thereof, which has the effect of deteriorating or tearing the applied wire, thus determining disturbances in the winding. On a constaté que cet inconvénient peut être éliminé lorsque les cylindres et/ou les bobines ou tubes sont munis à leurs extrémités ou c8tés en bout de bagues de roulement de préférence étroites, dont le diamètre extérieur ne dépasse celui de la partie de la bobine ou du cylindre, situé entre ces bagues, que d'une quantité telle que la différence des vitesses périphériques des deux diamètres soit inférieure, à 1 %. It has been found that this drawback can be eliminated when the cylinders and / or the coils or tubes are provided at their ends or end sides with preferably narrow rolling rings, the outside diameter of which does not exceed that of the part of the coil or of the cylinder, located between these rings, that of an amount such that the difference in the peripheral speeds of the two diameters is less than 1%. On obtient ainsi que le cylindre et la bobine ne soient en contact que par des surfaces étroites, voisines de leurs faces en bout:, tout en laissant un intervalle entre leurs parties cylindriques respectives, situées entre les bagues de rotation et appelées à former la zone de bobinage. Il s'ensuit que les premiers tours du fil appliqué dans la zone de bobinage n'entrent pas en contact avec la surface du cylindre, et cela jusqu'à l'institution du synchronisme de la bobine et du cylindre, le fil étant ainsi protégé contre toute détérioration. La différence entre les vitesses périphériques doit être inférieure à 1%, afin de maintenir les fluctuations de dévidage et de titre dans des limites admissibles. We thus obtain that the cylinder and the coil are in contact only by narrow surfaces, close to their end faces :, while leaving an interval between their respective cylindrical parts, located between the rotation rings and called to form the zone winding. It follows that the first turns of the wire applied in the winding zone do not come into contact with the surface of the cylinder, and this until the institution of synchronism of the coil and the cylinder, the wire being thus protected. against any deterioration. The difference between the peripheral speeds must be less than 1%, in order to keep the unwinding and titer fluctuations within acceptable limits. Les dessins annexés représentent schématiquement deux exemples d'exécution de l'objet de l'invention. La figure 1 montre la manière dont la bobine 1 est en prise avec le cylindre de friction 2. The accompanying drawings schematically represent two exemplary embodiments of the subject of the invention. Figure 1 shows how the spool 1 engages with the friction cylinder 2. La bobine est munie de bagues de roulement 3 de faible largeur, qui entrent en contact avec la surface du cylindre, tandis que la partie cylindrique de la bobine située entre les bagues 3, présente un diamètre inférieur au diamètre de celles-ci. On obtient ainsi un intervalle 5 entre le cylindre de friction et la bobine de sorte que le fil envidé 4 ne risque pas d'être comprimé et endommagé à cet endroit. The coil is provided with rolling rings 3 of small width, which come into contact with the surface of the cylinder, while the cylindrical part of the coil located between the rings 3, has a diameter smaller than the diameter of the latter. There is thus obtained a gap 5 between the friction cylinder and the spool so that the thread 4 does not run the risk of being compressed and damaged at this point. Comme montré dans la figure 2, l'intervalle au-dessus de la zone d'envidage peut aussi être réalisé en munissant le cylindre de friction 2 de bagues de roulement 3 d'un diamètre supérieur à celui de l'aire cylindrique restante de ce. cylindre, de sorte que la bobine cylindrique lisse 1 tourne seulement au contact des bagues de roulement 3 du cylindre de pression et qu'il existe un intervalle 5 pour les fils 4 entre le tube cylindrique lisse 1 et le cylindre de friction 2. **ATTENTION** fin du champ CLMS peut contenir debut de DESC **. As shown in figure 2, the gap above the emptying area can also be achieved by providing the friction cylinder 2 with bearing rings 3 of a diameter greater than that of the remaining cylindrical area of this. . cylinder, so that the smooth cylindrical coil 1 only rotates in contact with the bearing rings 3 of the pressure cylinder and there is a gap 5 for the threads 4 between the smooth cylindrical tube 1 and the friction cylinder 2. ** CAUTION ** end of field CLMS may contain start of DESC **.
