Description

L'invention a pour objet un nouveau procédé et une machine pour le bobinage des chutes résultant notamment du cisaillage des rives de tôles.The subject of the invention is a new process and a machine for winding off scrap resulting in particular from the shearing of the edges of sheets.

Dans les installations de laminage pour la fabrication de tôles il est nécessaire de réaliser un cisaillage des rives de celles-ci pour leur donner un bord rectiligne. Il en résulte la production de chutes en forme de rubans allongés qui doivent évidemment être récupérés et évacués. Des chutes du même genre sont également produites lorsqu'on effectue le refendage de tôles pour obtenir des tôles moins larges. Dans tous les cas, ces chutes minces et coupantes, et par conséquent dangereuses à manipuler, doivent être récupérées et évacuées.In rolling installations for the manufacture of sheets it is necessary to shear the edges thereof to give them a straight edge. This results in the production of falls in the form of elongated ribbons which obviously must be recovered and disposed of. Scraps of the same kind are also produced when splitting sheets to obtain narrower sheets. In all cases, these thin and sharp falls, and therefore dangerous to handle, must be recovered and disposed of.

Dans les installations classiques, les chutes sont récupérées au-dessous du plancher sur lequel est installée la machine de cisaillage ou de refendage. A l'endroit où est produite la chute en forme de ruban allongé, le plancher est en effet muni d'un orifice au-dessous duquel sont installés des moyens de guidage des chutes, par exemple une goulotte, qui amène le ruban jusqu'à une machine de bobinage.In conventional installations, the scraps are collected below the floor on which the shearing or slitting machine is installed. At the place where the drop in the form of an elongated ribbon is produced, the floor is in fact provided with an orifice below which are installed means for guiding the falls, for example a chute, which brings the ribbon up to a winding machine.

De telles machines comprennent généralement un mandrin constitué d'une tige s'étendant entre deux montants munis de parois latérales écartées l'une de l'autre et perpendiculaires à l'axe du mandrin. Celui-ci est muni d'autre part d'un organe d'accrochage de la chute.Such machines generally comprise a mandrel consisting of a rod extending between two uprights provided with side walls spaced from one another and perpendicular to the axis of the mandrel. This is provided on the other hand with a device for hooking the fall.

Au début du bobinage, un opérateur se trouve dans le sous-sol pour prendre l'extrémité du ruban arrivant par la goulotte d'amenée, et l'engager sur l'organe d'accrochage du mandrin. Celui-ci peut être entraîné en rotation autour de son axe mais est évidemment stoppé pendant cette opération.At the start of the winding, an operator is in the basement to take the end of the ribbon arriving through the feed chute, and engage it on the attachment member of the mandrel. This can be rotated around its axis but is obviously stopped during this operation.

Lorsque la chute est engagée sur le mandrin, l'opérateur s'écarte de la machine et referme une cage qui entoure celle-ci. Il peut alors, étant lui-même à l'abri, commander la rotation du mandrin sur lequel s'enroule la chute en forme de ruban allongé. Il se forme ainsi une bobine sur le mandrin dans l'espace limité par les deux parois latérales des montants et, généralement, un rouleau parallèle au mandrin et monté à l'extrémité d'un bras permettant de l'appuyer sur la bobine de façon à contrôler la formation de celle-ci.When the fall is engaged on the mandrel, the operator moves away from the machine and closes a cage which surrounds it. He can then, being himself sheltered, control the rotation of the mandrel on which the fall is wound in the form of an elongated ribbon. A coil is thus formed on the mandrel in the space limited by the two side walls of the uprights and, generally, a roller parallel to the mandrel and mounted at the end of an arm making it possible to press it on the coil so as to control the formation thereof.

Lorsque la bobine est formée, la rotation du mandrin est arrêtée et on commande le coulissement de celui-ci le long de son axe de façon à le retirer de la bobine. A cet effet, le mandrin est monté en porte-à-faux sur un support mobile qui est placé sur le côté extérieur de l'une des parois , et ce support peut se déplacer parallèlement à l'axe longitudinal du mandrin entre une position d'enroulement d'une bobine pour laquelle le mandrin passe à travers un orifice ménagé dans la paroi placée à côté de lui et s'étend au travers de l'espace d'enroulement jusqu'à l'autre paroi et une position d'éjection de la bobine pour laquelle le mandrin, ayant coulissé de l'autre côté de la paroi, est écarté de l'espace d'enroulement et libère ainsi la bobine. Celle-ci, qui peut être coincée entre les parois, est éventuellement repoussée par un bras d'éjection et tombe sur un plan incliné qui permet de l'évacuer.When the coil is formed, the rotation of the mandrel is stopped and the sliding thereof is controlled along its axis so as to remove it from the coil. To this end, the mandrel is cantilevered on a movable support which is placed on the outside of one of the walls, and this support can move parallel to the longitudinal axis of the mandrel between a position d winding of a coil for which the mandrel passes through an orifice in the wall placed next to it and extends through the winding space to the other wall and an ejection position of the coil for which the mandrel, having slid on the other side of the wall, is moved away from the winding space and thus frees the coil. This, which can be wedged between the walls, is possibly pushed back by an ejection arm and falls on an inclined plane which allows to evacuate it.

Toutes ces opérations ne seraient pas dangereuses si elles étaient toujours réalisées comme il vient d'être décrit, l'opérateur n'approchant de la machine que lorsque le mandrin est à l'arrêt. Cepen- dans, l'expérience montre que les règles de sécurité ne sont pas toujours respectées et que des accidents peuvent se produire.All these operations would not be dangerous if they were always carried out as just described, the operator only approaching the machine when the chuck is stopped. However, experience shows that safety rules are not always followed and that accidents can occur.

L'invention a pour objet un nouveau'procédé et une machine perfectionnée permettant de réaliser toutes les opérations automatiquement sans intervention manuelle, l'opérateur étant àtout moment éloigné de la machine.The subject of the invention is a new method and an improved machine making it possible to carry out all the operations automatically without manual intervention, the operator being at all times distant from the machine.

Selon l'invention, le mandrin étant stoppé et placé dans une position de démarrage intermédiaire entre la position d'éjection et la position d'enroulement de la bobine, on laisse d'abord une certaine quantité de ruban s'accumuler jusqu'à formation d'un paquet enchevêtré à proximité du mandrin ; on applique alors ledit paquet contre le mandrin et l'on fait coulisser ce dernier jusqu'en position d'enroulement de telle sorte que l'organe d'accrochage s'engage sur le paquet enchevêtré, le mandrin étant alors entraîné en rotation pour l'enroulement de la bobine.According to the invention, the mandrel being stopped and placed in an intermediate starting position between the ejection position and the reel winding position, a certain quantity of ribbon is first allowed to accumulate until formation a tangled bundle near the mandrel; said package is then applied against the mandrel and the latter is made to slide up to the winding position so that the latching member engages on the entangled package, the mandrel then being rotated for the winding of the coil.

La machine de bobinage perfectionnée selon l'invention est caractérisé en ce que les moyens de déplacement du support du mandrin sont susceptibles de placer ce dernier dans une position de démarrage intermédiaire entre la position d'enroulement et la position d'éjection de la bobine, l'organe d'accrochage se trouvant, dans cette position intermédiaire, décalé du côté du support par rapport au centre de l'espace d'enroulement ; l'installation comporte un organe d'accumulation d'une certaine longueur de chutes avant le bobinage jusqu'à formation d'un paquet enchevêtré à proximité du mandrin et des moyens d'application dudit paquet contre le mandrin en position de démarrage, l'organe d'accrochage s'engageant sur ledit paquet enchevêtré au passage de la position de démarrage à la position d'enroulement, le mandrin étant à l'arrêt en position de démarrage et entraîné en rotation en position d'enroulement.The improved winding machine according to the invention is characterized in that the means for moving the support of the mandrel are capable of placing the latter in a starting position intermediate between the winding position and the reel ejection position, the latching member being, in this intermediate position, offset from the side of the support relative to the center of the winding space; the installation comprises a device for accumulating a certain length of scrap before winding until a tangled bundle is formed near the mandrel and means for applying said bundle against the mandrel in the starting position, the latching member engaging on said tangled packet when passing from the starting position to the winding position, the mandrel being stopped in the starting position and driven in rotation in the winding position.

Sur la figure 1, on a représenté schématiquement l'ensemble 2 de l'installation.In Figure 1, there is shown schematically the assembly 2 of the installation.

Sur le plancher 1 de l'atelier est disposée une installation de refendage ou de cisaillage des rives d'une tôle 30 dont on a seulement représenté l'extrémité ; chaque chute 3 qui doit être récupérée se présente sous la forme d'un ruban allongé. La chute 3 tombe par un orifice 10, ménagé dans le plancher 1 à l'extrémité de la machine 2, dans une goulotte 4 qui la guide jusqu'à la machine de bobinage. Le bâti 5 de celle-ci est constitué essentiellement de deux montants 5l et 52 écartés l'un de l'autre et reliés entre eux par exemple par des profilés 53, l'ensemble formant ainsi une cage rigide délimitant un espace 6 à l'intérieur duquel sera réalisé le bobinage du.ruban 3.On the floor 1 of the workshop is arranged a slitting or shearing installation of the edges of a sheet 30 of which only the end has been shown; each fall 3 which must be recovered is in the form of an elongated ribbon. The chute 3 falls through an orifice 10, formed in the floor 1 at the end of the machine 2, in a chute 4 which guides it to the winding machine. The frame 5 thereof consists essentially of two uprights 5l and 52 spaced from one another and connected together for example by sections 53, the assembly thus forming a rigid cage delimiting a space 6 to the inside of which the ribbon will be wound. 3.

L'espace 6 est tiaversé par un mandrin 7 qui se compose d'une tige passant dans des orifices 54-55 ménagés dans les montants 51 et 52 et spécialement dans les parois internes des montants, respectivement 56-57 qui sont perpendiculaires à l'axe de la tige 7 et limitent l'espace d'enroulement 6.The space 6 is taversed by a mandrel 7 which is composed of a rod passing through orifices 54-55 formed in the uprights 51 and 52 and especially in the internal walls of the uprights, respectively 56-57 which are perpendicular to the axis of the rod 7 and limit the winding space 6.

Le mandrin 7 est monté en porte-à-faux, et de façon rotative autour de son axe longitudinal, sur un support 8 placé sur le côté extérieur du montant 51 c'est-à-dire du côté opposé à l'espace 6 par rapport aux montants. Le support 8 est déplaçable parallèlement à l'axe du mandrin 7 et, à cet effet, il peut être constitué par exemple d'un chariot monté sur des galets 81 roulant sur des rails 82 parallèles à l'axe longitudinal du mandrin. Le déplacement du chariot 8 peut être commandé par tous moyens, par exemple au moyen d'un vérin 83 dont le corps prend appui sur le socle fixe et dont l'extrémité de la tige est articulée en un point du chariot 8.The mandrel 7 is mounted in cantilever, and rotatably about its longitudinal axis, on a support 8 placed on the outside of the upright 51, that is to say on the side opposite the space 6 by compared to the amounts. The support 8 is movable parallel to the axis of the mandrel 7 and, for this purpose, it can consist for example of a carriage mounted on rollers 81 rolling on rails 82 parallel to the longitudinal axis of the mandrel. The movement of the carriage 8 can be controlled by any means, for example by means of a jack 83 the body of which bears on the fixed base and the end of the rod of which is articulated at a point on the carriage 8.

Le mandrin 7 est entraîné en rotation autour de son axe par un groupe motoréducteur 84 comprenant un embrayage et un frein qui permettent de contrôler la rotation du mandrin selon les besoins.The mandrel 7 is driven in rotation about its axis by a geared motor group 84 comprising a clutch and a brake which make it possible to control the rotation of the mandrel as required.

Les dispositions qui viennent d'être décrites sont bien connues et ne nécessitent pas de plus amples développements.The arrangements which have just been described are well known and do not require further development.

Dans les machines connues, le mandrin peut prendre deux positions. Tout d'abord pour l'enroulement, le mandrin est placé dans la position représentée sur la figure 2 où il s'étend entre les deux montants 51 et 52. Il est muni sur sa paroi d'un organe d'accrochage sur lequel on engage manuellement l'extrémité de la chute 3, le mandrin étant à l'arrêt. Lorsque l'extrémité du ruban est engagée le mandrin est mis en rotation jusqu'à former une botte ou bobine 9. A la fin de l'enroulement, le support 8 est ramené en arrière de façon que l'extrémité du mandrin se trouve à la hauteur du montant 51, en dégageant l'espace 6. La bobine 9 tombe alors sur un plan incliné qui l'évacue.In known machines, the mandrel can take two positions. First of all for winding, the mandrel is placed in the position shown in FIG. 2 where it extends between the two uprights 51 and 52. It is provided on its wall with a hooking member on which manually engages the end of the chute 3, the mandrel being stopped. When the end of the ribbon is engaged, the mandrel is rotated until it forms a boot or coil 9. At the end of the winding, the support 8 is brought back so that the end of the mandrel is at the height of the upright 51, clearing the space 6. The coil 9 then falls on an inclined plane which discharges it.

Selon une caractéristique essentielle de l'invention; le vérin 83 donnera au support 8 une position intermédiaire entre la position d'enroulement et la position d'éjection de la bobine.According to an essential characteristic of the invention; the jack 83 will give the support 8 an intermediate position between the winding position and the reel ejection position.

Sur les figures 4a, 5a, et 6a, on a représenté les trois positions du mandrin correspondant aux différentes phases du procédé, les figures 4,5, 6 donnant les positions des organes essentiels de la machine perfectionnée selon l'invention.In Figures 4a, 5a, and 6a, there are shown the three positions of the mandrel corresponding to the different phases of the process, Figures 4,5, 6 giving the positions of the essential organs of the improved machine according to the invention.

En effet, comme on le voit sur ces figures, selon l'invention, la goulotte 4 est prolongée à son extrémité par un organe 11 en forme de cuillère constitué essentiellement d'un fond 11 encadré par deux parois latérales 12 qui, dans la position représentée sur la figure 1, constituent une section de goulotte venant se placer dans le prolongement de la goulotte 4, et dont l'extrémité 13 passe au-dessous du mandrin 7 et est incurvée en forme de secteur cylindrique d'axe parallèle à celui du mandrin et entourant partiellement celui-ci. La cuillère 11 est articulée sur un axe 14 et un vérin 15 permet de la faire tourner autour de cet axe de façon à prendre les positions représentées sur les figures 4,5 et 6.Indeed, as can be seen in these figures, according to the invention, the chute 4 is extended at its end by a spoon-shaped member 11 consisting essentially of a bottom 11 framed by two side walls 12 which, in the position shown in FIG. 1, constitute a section of chute coming to be placed in the extension of the chute 4, the end of which 13 passes below the mandrel 7 and is curved in the form of a cylindrical sector with an axis parallel to that of the mandrel and partially surrounding the latter. The spoon 11 is articulated on an axis 14 and a jack 15 makes it possible to rotate it around this axis so as to assume the positions represented in FIGS. 4,5 and 6.

Pour permettre la rotation de la cuillère 11, le plan incliné sur lequel est évacuée la bobine 9 après son achèvement est constitué d'un volet 21 qui est articulé sur un axe 22 et dont la rotation autour de cet axe est commandée par un vérin 23 qui permet soit de placer le volet 21 en position haute au-dessous du mandrin 7 et de la bobine 9 lorsque la cuillère 11 est rabattue comme on l'a représentée sur la figure 6, soit de le rabattre pour permettre le passage de la cuillère 11, comme on l'a représenté sur les figures 4 et 5.To allow the spoon 11 to rotate, the inclined plane on which the coil 9 is discharged after its completion consists of a flap 21 which is articulated on an axis 22 and the rotation of which around this axis is controlled by a jack 23 which allows either to place the flap 21 in the high position below the mandrel 7 and the coil 9 when the spoon 11 is folded down as shown in FIG. 6, or to fold it down to allow the passage of the spoon 11, as shown in FIGS. 4 and 5.

Enfin, le bâti 5 est muni, de façon connue, d'un rouleau compacteur 24 monté à l'extrémité d'un bras articulé sur le bâti 5 et permettant de contrôler la formation de la bobine 9, et d'un bras éjecteur 26 qui repousse la bobine lorsque, par exemple, celle-ci est coincée entre les parois 56 et 57 et ne tombe pas d'elle-même sur le plan incliné 21 lorsque le mandrin est retiré à la fin de l'enroulement. Le bras 25 du rouleau compacteur et le bras d'éjection 26 peuvent être montés de façon avantageuse, sur les entretoises 53 reliant les deux montants 51 et 52 du bâti 5. Leurs mouvements peuvent être commandés par des vérins prenant àppui sur le même bâti et que n'a l'on i pas jugé utile de représenter sur le dessin puisqu'il s'agit de dispositions connues.Finally, the frame 5 is provided, in a known manner, with a compacting roller 24 mounted at the end of an articulated arm on the frame 5 and making it possible to control the formation of the coil 9, and of an ejector arm 26 which pushes the coil when, for example, it is wedged between the walls 56 and 57 and does not fall by itself on the inclined plane 21 when the mandrel is withdrawn at the end of the winding. The arm 25 of the compacting roller and the ejection arm 26 can be advantageously mounted on the spacers 53 connecting the two uprights 51 and 52 of the frame 5. Their movements can be controlled by jacks taking support on the same frame and which we did not consider useful to represent on the drawing since they are known arrangements.

Les différentes phases du procédé selon l'invention sont représentées schématiquement sur les figures 4,5 et 6.The different phases of the process according to the invention are shown diagrammatically in FIGS. 4,5 and 6.

Les figures 4 et 4a représentent la phase de démarrage. Dans cette phase, le volet 21 est rabattu et.la cuillère est relevée de telle sorte que le fond 11 soit dans le prolongement de la goulotte 4 et que son extrémité 13 entoure le mandrin 7 à une certaine distance d de celui-ci. De ce fait, la chute en forma de ruban 3 qui s'écoule dans la goulotte 4 peut venir s'accumuler dans l'extrémité 13 de la cuillère qui la retient. La goulotte 4 est constituée en tôle lisse de façon à éviter l'accrochage des chutes sur une quelconque aspérité. Elle part du niveau du plancher 1 devant la cisaille de rives 2 et descend selon une pente suffisante pour assurer le bon dégagement des rives au démarrage et pendant le bobinage. A cet effet, il peut être avantageux d'installer la goulotte 4 sur des plots élastiques 41 permettant sa vibration.Figures 4 and 4a show the start-up phase. In this phase, the flap 21 is folded et.la spoon is raised so that the bottom 11 is in the extension of the chute 4 and that its end 13 surrounds the mandrel 7 at a certain distance d thereof. As a result, the fall in the form of ribbon 3 which flows in the chute 4 can come to accumulate in the end 13 of the spoon which retains it. The chute 4 is made of smooth sheet metal so as to avoid catching the falls on any roughness. It starts from the level of the floor 1 in front of the edge shears 2 and descends along a slope sufficient to ensure the good clearance of the edges at start-up and during winding. To this end, it may be advantageous to install the chute 4 on elastic pads 41 allowing its vibration.

Par ailleurs, comme on l'a représenté schématiquement sur la figure 4a, la largeur de la goulotte 4 diminue et ses parois latérales se rapprochent du montant 52 la cuillère 11 étant elle-même placée dans le prolongement de la goulotte 4 c'est-à-dire décalée vers le montant 52 par rapport au centre de l'espace d'enroulement 6. Il se forme ainsi au-dessous du mandrin et du côté du montant 52 dans lequel s'engage l'extrémité en porte-à-faux du mandrin, un paquet de chutes qui s'enchevètrent dans l'extrémité 13 de la cuillère 11. Dans la position intermédiaire qui est représentée sur la figure 4a, l'organe d'accrochage des chutes ménagé sur le mandrin se trouve décalé vers le montant 51 par rapport au centre de l'espace 6. Comme on l'a représenté sur la figure 1, il est avantageux de donner à l'extrémité du mandrin une section triangulaire de façon à ménager trois parties évidées dans lesquelles seront placés trois ergots 71 constituant des organes d'accrochage. Dans la position de la figure 4a, les ergots 71 sont décalés vers le montant 51 et les chutes s'accumulent dans l'extrémité de la cuillère 13, du côté du montant 52.Furthermore, as shown diagrammatically in FIG. 4a, the width of the chute 4 decreases and its side walls approach the upright 52, the spoon 11 being itself placed in the extension of the chute 4 that is i.e. offset towards the upright 52 with respect to the center of the winding space 6. It thus forms below the mandrel and on the side of the upright 52 in which the cantilevered end engages of the mandrel, a packet of scraps which become entangled in the end 13 of the spoon 11. In the intermediate position which is shown in FIG. 4a, the device for hooking the scraps formed on the mandrel is shifted towards the amount 51 with respect to the center of the space 6. As shown in FIG. 1, it is advantageous to give the end of the mandrel a triangular section so as to provide three hollowed out parts in which three pins will be placed 71 constituting attachment members. In the position in FIG. 4a, the lugs 71 are offset towards the upright 51 and the drops accumulate in the end of the spoon 13, on the side of the upright 52.

Lorsque des chutes se sont ainsi accumulées jusqu'à former un paquet enchevêtré, on commande au moyen du vérin 15 un léger soulèvement de la cuillère 11 dont l'extrémité 13 applique le paquet enchevêtré contre la partie du mandrin 7 ayant une section triangulaire.When scraps have thus accumulated to form an entangled pack, a slight lifting of the spoon 11 is controlled by means of the jack 15, the end 13 of which applies the entangled pack against the part of the mandrel 7 having a triangular section.

On commande alors au moyen du vérin 83 l'avancement du mandrin jusqu'à la position d'enroulement, l'extrémité du mandrin venant avants geusement se conter dans une contrepointe 58 placée sur la paroi extérieure du montant 52. Dans cette position, les ergots 71 sont arrivés à proximité de la paroi 57 et, au cours de leur déplacement, se sont accrochés dans le paquet de rubans enchevêtrés appliqué contre mandrin.The advancement of the mandrel to the winding position is then controlled by means of the actuator 83, the end of the mandrel coming advantageously to be counted in a tailstock 58 placed on the external wall of the upright 52. In this position, the lugs 71 arrived near the wall 57 and, during their movement, became caught in the bundle of entangled ribbons applied against the mandrel.

La cuillère 11 étant maintenue dans cette position d'application contre le mandrin, on abaisse le rouleau compacteur 24 et en même temps on commande la rotation du mandrin autour de son axe. Le ruban étant bien engagé sur les organes d'accrochage, une bobine commence à se former. On peut alors au moyen du vérin 15, abaisser la cuillère 11 dans la position représentée sur la figure 6 de façon à permettre l'enroulement de la bobine entre les deux parois 56 et 57 et le rouleau compacteur 24.The spoon 11 being held in this position of application against the mandrel, the compacting roller 24 is lowered and at the same time the rotation of the mandrel is controlled around its axis. The tape is well engaged on the fastening members, a coil begins to form. It is then possible, by means of the jack 15, to lower the spoon 11 to the position shown in FIG. 6 so as to allow the coil to be wound between the two walls 56 and 57 and the compacting roller 24.

Dès que la cuillère 11 est abaissée, le vérin 23 peut commander le relèvement de la table 21 qui vient se placer sous le mandrin 7. Lorsqu'on a fini d'enrouler la chute ou bien lorsque la bobine a atteint sa dimension maximale, le mandrin est arrêté et est reculé dans sa position d'éjection comme on l'a représenté sur la figure 6a ; la bobine 9 qui vient d'être enroulée tombe alors sur la table 21, le bras 26 favorisant éventuellement cette éjection.As soon as the spoon 11 is lowered, the jack 23 can command the raising of the table 21 which is placed under the mandrel 7. When the reel has been wound up or when the spool has reached its maximum dimension, the mandrel is stopped and is moved back to its ejection position as shown in FIG. 6a; the coil 9 which has just been wound then falls on the table 21, the arm 26 possibly promoting this ejection.

Il apparaît bien que toutes les opérations ont été effectuées sans aucune intervention manuelle. Pour augmenter la sécurité de l'installation, il est avantageux d'éloigner l'opérateur de la machine en le plaçant par exemple sur le plancher 1 d'où il pourra surveiller et commander à distance les opérations en observant la machine par exemple à travers un orifice 15 ménagé dans le plancher 1 ou bien, de préférence, sur un écran de télévision relié à une ou plusieurs caméras 16 placées judicieusement de façon à observer les organes essentiels de la machine pendant toutes les phases du procédé.It appears that all the operations were carried out without any manual intervention. To increase the safety of the installation, it is advantageous to move the operator away from the machine by placing it for example on the floor 1 from where he can remotely monitor and control the operations by observing the machine for example through an orifice 15 formed in the floor 1 or, preferably, on a television screen connected to one or more cameras 16 placed judiciously so as to observe the essential organs of the machine during all the phases of the process.

Grâce aux dispositions qui viennent d'être décrites, le bobinage s'effectue ainsi automatiquement dans les meilleures conditions de sécurité.Thanks to the arrangements which have just been described, the winding is thus carried out automatically under the best safety conditions.

Il est bien évident que les dispositions qui viennent d'être décrites pourraient faire l'objet de variantes et que l'invention ne se limite pas uniquement au mode de réalisation que l'on a représenté à titre d'exemple.It is obvious that the arrangements which have just been described could be subject to variants and that the invention is not limited solely to the embodiment which has been shown by way of example.
