Description

On sait qu'avant le retordage proprement dit de deux fils, on les assemble souvent juste avant leur introduction dans l'alésage central de l'axe de la broche à retordre. Pour ce faire, on dispose deux bobines l'une au-dessus de l'autre dans le pot de la broche et l'on fait dévider les deux fils ensemble. Mais cette disposition présente des difficultés de défilement du fil de la bobine inférieure.It is known that before the actual twisting of two wires, they are often assembled just before their introduction into the central bore of the axis of the twist spindle. To do this, we have two coils one above the other in the spindle jar and we unwind the two wires together. However, this arrangement presents difficulties in running the wire from the lower spool.

En effet, ce fil en se dévidant frotte sur le pourtour de la bobine supérieure de sorte qu'il est freiné. Par conséquent, il ne se place pas parallèlement à l'autre fil avec la même tension et il a en outre tendance à venir s'enrouler autour de l'axe de la broche en passant sous la seconde bobine ce qui entraîne, bien entendu sa rupture.Indeed, this wire in unwinding rubs on the periphery of the upper reel so that it is braked. Consequently, it is not placed parallel to the other wire with the same tension and it moreover tends to come to wind around the axis of the spindle while passing under the second reel which involves, of course its rupture.

De toute manière l'assemblage des deux fils ne s'effectue pas de manière satisfaisante de sorte que finalement on obtient un fil mal retordu.In any case, the assembly of the two wires is not carried out satisfactorily so that ultimately a poorly twisted wire is obtained.

La solution générale consiste à placer un disque en dessous de la bobine supérieure et au-dessus de celle inférieure. Mais celle-ci n'assure sa fonction que dans les limites d'un certain rapport entre son diamètre extérieur et le diamètre correspondant des bobines.The general solution is to place a disc below the upper spool and above the lower one. However, the latter performs its function only within the limits of a certain relationship between its outside diameter and the corresponding diameter of the coils.

De plus un tel disque ne permet pas de résoudre un autre problème posé lorsqu'on a affaire à des fils glissants par rapport aux bobines.In addition, such a disc does not make it possible to solve another problem posed when dealing with threads sliding with respect to the coils.

Dans ce cas en effet, les spires de la bobine supérieure qui ne sont pas retenues par le disque risquent de s'ébouler et de se rompre du fait de l'apparition d'un phénomène de cabestan autour de l'axe de la broche. Pour éviter le passage du fil en dessous du disque, la bobine est généralement posée sur une peau de mouton qui n'empêche pas les spires de s'ébouler.In this case, in fact, the turns of the upper coil which are not retained by the disc risk collapsing and breaking due to the appearance of a capstan phenomenon around the axis of the spindle. To avoid the passage of the wire below the disc, the spool is generally placed on a sheepskin which does not prevent the turns collapse.

On connaît par la demande de brevet allemand DE-A628 27 814 un disque dont la périphérie est pourvue de lamelles élastiques. Mais celles-ci ne peuvent se déformer que si la tension du fil est suffisante. De plus la déformation desdites lamelles n'est pas automatiquement fonction du diamètre de la bobine supérieure.We know from the German patent application DE-A628 27 814 a disc whose periphery is provided with elastic strips. However, these can only deform if the thread tension is sufficient. Furthermore, the deformation of said strips is not automatically a function of the diameter of the upper coil.

Dans la demande de brevet allemand DE-A 28 27 853, la périphérie du disque est orientable radialement et latéralement mais là encore la déformation n'est provoquée que par la tension du fil ; en outre, elle n'est pas automatiquement fonction du diamètre de la bobine supérieure.In German patent application DE-A 28 27 853, the periphery of the disc can be oriented radially and laterally, but here again the deformation is only caused by the tension of the thread; moreover, it is not automatically a function of the diameter of the upper coil.

Avec ces deux dispositifs il existe une réaction élastique antagoniste sur le fil qui risque de provoquer son usure voire sa rupture.With these two devices there is an antagonistic elastic reaction on the wire which risks causing it to wear or even break.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à ces inconvénients et à permettre la réalisation d'un dispositif propre à guider le déroulement du fil de la bobine inférieure en variant de diamètre au fur et à mesure de la diminution de celui de la bobine supérieure, indépendamment de la tension du fil et sans engendrer d'action antagoniste à son égard.The improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a device capable of guiding the unwinding of the wire from the lower spool, varying in diameter as the reduction in that of the upper coil, independently of the tension of the thread and without generating any antagonistic action towards it.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une vue d'ensemble d'un dispositif suivant l'invention placé à l'intérieur du pot d'une broche à retordre dans lequel se trouvent deux bobines superposées dont les fils doivent être assemblés avant d'être retordus.
  • Fig. 2 est une vue semblable à celle de fig. 1 mais montrant les bobines lorsqu'elles ne contiennent pratiquement plus de fil. On y a illustré la nouvelle position du dispositif suivant l'invention.
  • Fig. 3 est une vue par dessus du dispositif suivant l'invention représenté à l'état déployé.
  • Fig. 4 en est une vue de détail à plus grande échelle.
  • Fig. 5 à 7 illustrent de manière schématique les différentes positions du dispositif suivant l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is an overall view of a device according to the invention placed inside the pot of a twisting spindle in which there are two superimposed coils, the wires of which must be assembled before being twisted.
  • Fig. 2 is a view similar to that of FIG. 1 but showing the coils when they do not contain practically no more thread. The new position of the device according to the invention has been illustrated there.
  • Fig. 3 is a top view of the device according to the invention shown in the deployed state.
  • Fig. 4 is a detail view on a larger scale.
  • Fig. 5 to 7 schematically illustrate the different positions of the device according to the invention.

On a représenté en fig. 1 une broche à double torsion 1 supportant comme à l'accoutumée un pot 2 dans lequel sont disposées, l'une au-dessus de l'autre, deux bobines 3 et 4 maintenues fixes par rapport à l'axe 5 de la broche 1. A partir des bobines partent deux fils 6, 7 qui sont engagés dans l'alésage central 5a de l'axe 5 de manière à être assemblés l'un avec l'autre avant le retordage. On aperçoit les deux fils réunis en dessous de la figure, à leur sortie de l'alésage 5a.There is shown in fig. 1 a double twist spindle 1 supporting as usual a pot 2 in which are arranged, one above the other, two coils 3 and 4 kept fixed relative to the axis 5 of the spindle 1 From the coils leave two wires 6, 7 which are engaged in the central bore 5a of the axis 5 so as to be assembled with each other before the twisting. We see the two wires joined below the figure, at their exit from the bore 5a.

On dispose sous la bobine supérieure 4 un dispositif suivant l'invention affecté de la référence générale 8, et qui coopère avec la périphérie de la base de la bobine 4.A device according to the invention is given under the upper coil 4, given the general reference 8, and which cooperates with the periphery of the base of the coil 4.

Le dispositif 8 a été représenté en fig. 1 dans la position qu'il occupe lorsque la bobine 4 est pleine alors qu'en fig. 2 sa position correspond à la fin du dévidage du fil des bobines.The device 8 has been shown in FIG. 1 in the position it occupies when the coil 4 is full while in fig. 2 its position corresponds to the end of the unwinding of the coil wire.

Le dispositif 8 comprend essentiellement d'une part un disque 9 immobilisé angulairement par rapport à l'axe 5 qui est lui-même stabilisé en rotation comme cela est bien connu dans les broches à retordre, et d'autre part une corolle 10. La périphérie du disque 9 comprend un épaulement 9a tourné vers l'extérieur et dans lequel est disposée une multiplicité de blocs 11 cylindriques comportant chacun des moyens de retenue des extrémités de deux arceaux 12 qui s'entrelacent pour former la corolle 10. L'ensemble des blocs 11 est retenu dans l'épaulement 9a du disque au moyen d'un jonc circulaire élastique 13 tel qu'un élastique, un ressort ou analogue qui est tressé par rapport aux arceaux 12 comme on le voit mieux en fig. 4. En fait le jonc 13 passe alternativement devant et derrière les extrémités des arceaux 12 associés à deux blocs 11 consécutifs.The device 8 essentially comprises on the one hand a disc 9 angularly immobilized with respect to the axis 5 which is itself stabilized in rotation as is well known in the twisting pins, and on the other hand a corolla 10. The periphery of the disc 9 comprises a shoulder 9a facing outwards and in which is arranged a multiplicity of cylindrical blocks 11 each comprising means for retaining the ends of two arches 12 which intertwine to form the corolla 10. All of the blocks 11 is retained in the shoulder 9a of the disc by means of an elastic circular ring 13 such as an elastic, a spring or the like which is braided with respect to the arches 12 as best seen in FIG. 4. In fact the rod 13 passes alternately in front of and behind the ends of the arches 12 associated with two consecutive blocks 11.

Comme cela est bien représenté, le jonc 13 coopère avec les extrémités des arceaux 12 et le dessus des blocs 11.As is well represented, the rod 13 cooperates with the ends of the arches 12 and the top of the blocks 11.

Les arceaux peuvent être réalisés au moyen de brins de matière plastique résistante telle que le "nylon" ou analogue et leurs extrémités peuvent être engagées dans des blocs 11 également en matière plastique par rapport auxquels elles sont soudées ou fixées autrement.The arches can be made by means of strands of resistant plastic material such as "nylon" or the like and their ends can be engaged in blocks 11 also made of plastic material with respect to which they are welded or otherwise fixed.

Comme illustré en fig. 5 le jonc élastique 13 plaque les différents blocs 11 au fond de l'épaulement 9a du disque 9, cet épaulement affectant la forme la plus appropriée. On pourrait en vue de parfaire le maintien des blocs 11 par rapport à l'épaulement 9a leur faire comporter des picots centraux lla propres à s'engager dans des trous pratiqués dans des oreilles radiales 14a d'une couronne 14 associée au disque 9. L'épaulement 9a pourrait aussi être arrondi de manière à mieux coopérer avec la périphérie des blocs. Ceux-ci étant définis comme pivotant dans l'épaulement 9a, on comprend aisément que le jonc élastique 13 charge la corolle 10 en direction du haut de telle sorte que, comme illustré en fig. 1, elle vient porter contre la périphérie de la bobine 4, c'est-à-dire contre la nappe de fil qu'elle supporte. Au fur et à mesure que le fil 7 est déroulé de la bobine 4, la nappe en question diminue de diamètre et la corolle 10 du dispositif 8 se referme petit à petit en gardant le contact avec sa périphérie. Ainsi le fil 6 qui est déroulé à partir de la bobine inférieure 3 coopère-t-il avec la périphérie de la corolle et non point avec celle de la bobine 4 de telle sorte que la résistance à son défilement est pratiquement nulle. Ainsi le frottement sur la corolle ne risque pas d'engendrer sur le fil 6 des tensions qui nuiraient à son bon assemblage avec le fil 7 issu de la bobine supérieure 4.As illustrated in fig. 5 the elastic ring 13 plates the various blocks 11 at the bottom of the shoulder 9a of the disc 9, this shoulder affecting the most appropriate shape. One could in order to perfect the maintenance of the blocks 11 relative to the shoulder 9a make them have central pins lla adapted to engage in holes made in radial ears 14a of a crown 14 associated with the disc 9. L 'shoulder 9a could also be rounded so as to better cooperate with the periphery of the blocks. These being defined as pivoting in the shoulder 9a, it is easily understood that the elastic rod 13 loads the corolla 10 in the upward direction so that, as illustrated in FIG. 1, it comes to bear against the periphery of the coil 4, that is to say against the sheet of wire which it supports. As the wire 7 is unwound from the spool 4, the ply in question decreases in diameter and the corolla 10 of the device 8 closes little by little while keeping contact with its periphery. Thus the wire 6 which is unwound from the lower coil 3 cooperates with the periphery of the corolla and not point with that of the coil 4 so that the resistance to its running is practically zero. Thus friction on the corolla does not risk generating on the wire 6 tensions which would interfere with its proper assembly with the wire 7 from the upper coil 4.

On a illustré en fig. 7 et 2 la position de la corolle 10 lorsque les deux bobines sont pratiquement vides. On voit qu'à ce moment le jonc 13 fait porter la corolle 10 contre le socle 4a de la bobine 4, cette corolle étant alors en position pratiquement verticale. Lorsqu'on veut enlever l'âme centrale de la bobine 4 et charger une nouvelle bobine pleine, il suffit d'actionner la corolle de manière à la rabattre vers le bas, elle passe alors par un point d'équilibre instable pour venir en dessous de l'horizontale porter contre la périphérie 9b du disque 9, position dans laquelle elle est stable. Bien entendu cette position stable est rendue possible par l'action du jonc élastique 13 sur le corolle 10. Le dessus du disque 9 étant complètement dégagé, il est très facile d'y installer une bobine 4. Il va de soi que l'échange de la bobine 3 ne s'effectue qu'après démontage du dispositif 8 qui est remis en place dans le pot 2 après cette opération.Illustrated in fig. 7 and 2 the position of the corolla 10 when the two coils are practically empty. We see that at this time the rod 13 causes the corolla 10 to bear against the base 4a of the coil 4, this corolla then being in a practically vertical position. When you want to remove the central core of the coil 4 and load a new full coil, simply activate the corolla so as to fold it down, it then passes through an unstable equilibrium point to come below of the horizontal bear against the periphery 9b of the disc 9, position in which it is stable. Of course, this stable position is made possible by the action of the elastic ring 13 on the corolla 10. The top of the disc 9 being completely free, it is very easy to install a coil 4. It goes without saying that the exchange of the coil 3 is only carried out after disassembly of the device 8 which is replaced in the pot 2 after this operation.

Une fois les deux bobines replacées dans ce dernier, la corolle est à nouveau déformée manuellement en direction du haut pour repasser le point d'équilibre instable afin qu'elle vienne naturellement porter de manière élastique contre la périphérie de la nappe de la bobine 4.Once the two coils have been replaced in the latter, the corolla is again deformed manually in the upward direction to pass the unstable equilibrium point so that it naturally comes to bear elastically against the periphery of the web of the coil 4.

On note que la corolle 10 pourrait être réalisée par tout autre moyen que celui d'arceaux 12 associés à des blocs 11 ; on peut citer à titre d'exemple non limitatif une corolle composée de pétales se déployant ou se rétractant à la manière du diaphragme d'un appareil photographique.It should be noted that the corolla 10 could be produced by any other means than that of arches 12 associated with blocks 11; by way of nonlimiting example, a corolla made up of petals that deploy or retract like the diaphragm of a camera can be cited.
