Description

La présente invention concerne le domaine des machines à dérouler en continu des matières en bandes, en particulier des bobines de PVC ou d'étiquettes ou d'autres matières relativement peu flexibles, pour alimenter en continu, des machines d'impression, de façonnage ou autre, et a pour objet un dispositif de raccordement bout à bout pour une telle machine à dérouler en continu.The present invention relates to the field of continuously unroll strip material, in particular reels of PVC or labels or other relatively inflexible materials, for feed continuously, printing, shaping or other machines, and relates to an end-to-end connection device for such a continuous unrolling machine.

Le raccordement bout à bout entre bandes de matière finissante et nouvelle, en particulier en matière relativement peu flexible est généralement effectué par mise en oeuvre de deux bandes adhésives collées simultanément de part et d'autre du joint entre les bandes sur les extrémités aboutées. Ce raccordement doit pouvoir résister à la traction exercée sur la bande pendant le déroulement, ainsi que pendant les opérations ultérieures de façonnage ou autre.The end-to-end connection between strips of finishing material and new, especially in relatively inflexible material is generally carried out by using two glued adhesive tapes simultaneously on either side of the joint between the strips on the ends butted. This connection must be able to withstand the traction exerted on the tape during unwinding, as well as during subsequent operations shaping or other.

Pour réaliser un tel raccordement bout à bout, il a été proposé différents dispositifs de coupe et de raccordement, notamment par WO-A-98/02 372 et par GB-A-2 148 856, permettant une coupe des bandes de matière finissante et nouvelle, suivie d'un raccordement bout à bout avec application d'une bande adhésive de chaque côté du joint entre bandes. Le raccordement ainsi obtenu est généralement fiable.To make such an end-to-end connection, it has been proposed various cutting and connecting devices, in particular by WO-A-98/02 372 and by GB-A-2 148 856, allowing a cutting of the strips of finishing and new material, followed by an end-to-end connection with application of an adhesive strip on each side of the joint between strips. The connection thus obtained is generally reliable.

Cependant, ces dispositifs connus, qui sont équipés d'un moyen d'amenée des bandes adhésives devant le joint, présentent l'inconvénient de nécessiter un encombrement important de leur poste de coupe et de raccordement, afin de permettre la mise en place des bandes adhésives sur les applicateurs. En outre, les bandes adhésives utilisées étant généralement à fort pouvoir adhésif, elles ont tendance à se vriller et ainsi à empêcher un aboutement et un raccordement corrects pouvant avoir pour conséquence un bourrage de la machine au niveau du poste de coupe et de raccordement et/ou une interruption du déroulage en continu.However, these known devices, which are equipped with a means adhesive tape in front of the joint, have the disadvantage of require a large footprint of their cutting station and connection, to allow the installation of adhesive strips on the applicators. In addition, the adhesive tapes used are generally with strong adhesive power, they tend to twist and thus prevent a correct connection and connection which may result in a jamming of the machine at the cutting and connection station and / or an interruption of the continuous unwinding.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de raccordement bout à bout pour une machine à dérouler en continu permettant un raccordement bout à bout entre deux bandes, finissante et nouvelle, garantissant une jonction parfaite entre lesdites bandes et évitant tout risque d'incident lors du raccordement. The object of the present invention is to overcome these drawbacks by providing an end-to-end connection device for a unroll continuously allowing an end-to-end connection between two strips, finishing and new, guaranteeing a perfect junction between said strips and avoiding any risk of incident during connection.

A cet effet, le dispositif de raccordement bout à bout pour une machine à dérouler en continu, comportant au moins un moyen de déroulage de deux bobines, un accumulateur de bande et un dispositif de raccordement et de coupe, est caractérisé en ce qu'il est essentiellement constitué par un poste de coupe et de raccordement bout à bout des bandes comportant deux ensembles opposés pivotants de préparation, de coupe et de raccordement des bandes finissante et nouvelle munis chacun d'un moyen de guidage et de maintien provisoire desdites bandes.To this end, the end-to-end connection device for a continuous unrolling machine, comprising at least one means of unwinding of two reels, a tape accumulator and a device for connection and cutting, is characterized in that it is essentially consisting of a cutting station and end-to-end connection of the strips comprising two opposite pivoting assemblies for preparation, cutting and for connecting the finishing and new bands, each provided with a means for guiding and temporarily holding said strips.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale d'une machine à dérouler pourvue d'un dispositif de raccordement bout à bout conforme à l'invention ;
  • la figure 2 est une vue partielle en élévation latérale et en coupe, à plus grande échelle, représentant le détail du dispositif de coupe et des moyens d'application de bandes adhésives du poste de coupe et de raccordement bout à bout, et
  • la figure 3 est une vue schématique en élévation latérale de l'un des ensembles pivotants de préparation, de coupe et de raccordement des bandes finissante et nouvelle.
    • The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a side elevational view of an unwinding machine provided with an end-to-end connection device according to the invention;
  • FIG. 2 is a partial view in side elevation and in section, on a larger scale, showing the detail of the cutting device and of the means of applying adhesive strips of the cutting station and of end-to-end connection, and
  • Figure 3 is a schematic side elevational view of one of the pivoting assemblies for preparing, cutting and connecting the finishing and new strips.

    • La figure 1 des dessins annexés représente une machine à dérouler en continu permettant un déroulage en continu avec raccordement bout à bout entre deux bandes finissante 1 et nouvelle 2 et comportant au moins un moyen 3 de déroulage de deux bobines, un accumulateur de bande 4 et un dispositif de raccordement et de coupe.Figure 1 of the accompanying drawings shows a machine continuous unwinding allowing continuous unwinding with connection end to end between two finishing strips 1 and new 2 and comprising at less means 3 for unwinding two reels, a tape accumulator 4 and a connection and cutting device.

    Conformément à l'invention, le dispositif de raccordement et de coupe est essentiellement constitué par un poste 5 de coupe et de raccordement bout à bout des bandes 1 et 2 comportant deux ensembles opposés pivotants 6 de préparation, de coupe et de raccordement des bandes finissante 1 et nouvelle 2 munis chacun d'un moyen 7 de guidage et de maintien provisoire desdites bandes.In accordance with the invention, the device for connecting and cutting is essentially constituted by a station 5 for cutting and end-to-end connection of strips 1 and 2 comprising two sets pivoting opposites 6 for preparing, cutting and connecting the strips graduating 1 and new 2 each provided with a means 7 for guiding and provisional maintenance of said bands.

    La machine à dérouler conforme à l'invention est essentiellement destinée au déroulage de bobines de matières relativement rigides telles que du PVC, ou formant support d'étiquettes, afin d'obtenir un raccordement bout à bout parfaitement fiable, c'est-à-dire garantissant la résistance à la séparation par arrachement de la bande au niveau de la jonction par l'intermédiaire de bandes adhésives.The unrolling machine according to the invention is essentially intended for unwinding relatively coils of material rigid such as PVC, or forming a label support, in order to obtain a perfectly reliable end-to-end connection, i.e. guaranteeing resistance to separation by tearing of the strip at the level of the joining via adhesive strips.

    A cet effet, il s'agit d'obtenir un aboutement parfait entre bandes finissante et nouvelle et une application optimale des bandes adhésives sur les extrémités correspondantes desdites bandes au niveau du joint, tout en évitant un vrillage, dénommé "curling", des bouts de bandes à raccorder, et desdites bandes adhésives avant le raccordement ou au cours du raccordement.To this end, it is a question of obtaining a perfect abutment between finishing and new tapes and optimal application of tapes adhesive on the corresponding ends of said strips at the level of the joint, while avoiding a twist, called "curling", ends of strips to to connect, and to said adhesive strips before connection or during of the connection.

    Cet objectif est atteint par la mise en oeuvre du poste 5 de coupe et de raccordement bout à bout des bandes 1 et 2.This objective is achieved by the implementation of the cutting station 5 and end-to-end connection of strips 1 and 2.

    Selon une caractéristique de l'invention, les deux ensembles opposés pivotants 6 de préparation, de coupe et de raccordement des bandes finissante 1 et nouvelle 2 munis chacun d'un moyen 7 de guidage et de maintien provisoire desdites bandes sont complémentaires et consistent chacun en un châssis pivotant monté sur un arbre de support du bâti 8 de la machine et comportant, à leur extrémité opposée audit arbre de support, le moyen 7 de guidage et de maintien provisoire des bandes, un caisson 9, pouvant coulisser parallèlement audit moyen 7 de guidage et de maintien provisoire et au sens de défilement des bandes 1 et 2, étant guidé dans ledit châssis pivotant 6 et portant, d'une part, une partie 10 ou 10' d'un dispositif de coupe et, d'autre part, un moyen 11 de réception et d'application d'une bande adhésive.According to a characteristic of the invention, the two sets pivoting opposites 6 for preparing, cutting and connecting the strips graduating 1 and new 2 each provided with a means 7 for guiding and provisional retention of said bands are complementary and consist each in a pivoting frame mounted on a support shaft of the frame 8 of the machine and comprising, at their end opposite to said support shaft, the means 7 for temporarily guiding and holding the bands, a box 9, capable of sliding parallel to said means 7 for guiding and holding provisional and in the direction of travel of the bands 1 and 2, being guided in said pivoting frame 6 and carrying, on the one hand, a 10 or 10 'part of a device cutting and, on the other hand, a means 11 for receiving and applying a band-Aid.

    Chaque châssis pivotant constituant l'un des ensembles opposés pivotants 6 de préparation, de coupe et de raccordement des bandes finissante 1 et nouvelle 2 est avantageusement relié à un moyen de pivotement actionné par un vérin (non représentés) et est muni, d'une part, d'un actionneur 12 de déplacement du caisson 9 parallèlement au moyen 7 de guidage et de maintien provisoire, sous forme d'un vérin ou analogue et, d'autre part, de moyens 13 de guidage coulissant du caisson 9, tels que des rails ou barres (figure 3).Each pivoting frame constituting one of the opposite assemblies swivels 6 for preparing, cutting and connecting the strips graduating 1 and new 2 is advantageously connected to a means of pivoting actuated by a jack (not shown) and is provided, on the one hand, an actuator 12 for moving the box 9 parallel to the means 7 for guidance and provisional maintenance, in the form of a jack or the like and, on the other hand, means 13 for sliding guide of the box 9, such as rails or bars (Figure 3).

    Par ailleurs, chaque châssis pivotant 6 est pourvu d'un dispositif 14 de pinçage du début d'une nouvelle bande 2, ce dispositif 14 se présentant avantageusement sous forme d'une traverse mobile montée sur l'une des faces dudit châssis pivotant adjacentes à celle formant le moyen 7 de guidage et de maintien provisoire. Cette traverse mobile est guidée en déplacement par rapport à la face correspondante par l'intermédiaire de guides (non représentés) montés latéralement et perpendiculairement à cette dite face et est actionnée en déplacement de pinçage contre la face par l'intermédiaire d'un vérin non représenté, le retour en position d'écartement de ladite face étant assuré par des ressorts de rappel (non représentés) montés sur lesdits guides.Furthermore, each pivoting frame 6 is provided with a device 14 pinching the start of a new strip 2, this device 14 is advantageously having the form of a movable cross member mounted on one of the faces of said pivoting frame adjacent to that forming the means 7 guidance and provisional maintenance. This movable cross member is guided in displacement relative to the corresponding face by means of guides (not shown) mounted laterally and perpendicular to this said face and is actuated by pinching movement against the face by via a jack not shown, the return to the spacing position of said face being provided by return springs (not shown) mounted on said guides.

    Ainsi, la nouvelle bande 2 peut être parfaitement maintenue sur le châssis pivotant 6 en vue des opérations ultérieures de coupe et de raccordement bout à bout avec la bande finissante 1.Thus, the new band 2 can be perfectly maintained on the pivoting frame 6 for subsequent cutting and end to end connection with the finishing strip 1.

    Le dispositif de coupe est constitué par deux parties 10 et 10' consistant respectivement en un couteau 10 et en un contre-couteau 10' montés, l'un dans l'un des caissons 9 et l'autre dans l'autre caisson 9 de manière parfaitement symétrique (figure 2). Le couteau 10 et le contre-couteau 10' sont actionnés chacun dans une direction de rapprochement mutuel, par l'intermédiaire d'un vérin, non représenté, monté sur le caisson correspondant et sont chargés, en outre, chacun par un organe 15 de rappel en position de repos, par exemple sous forme d'une tige d'extraction chargée par un ressort de rappel.The cutting device consists of two parts 10 and 10 ' consisting respectively of a knife 10 and a counter knife 10 ' mounted, one in one of the boxes 9 and the other in the other box 9 of perfectly symmetrical (Figure 2). Knife 10 and counter knife 10 'are each actuated in a direction of approximation mutual, by means of a jack, not shown, mounted on the box corresponding and are charged, in addition, each by a reminder member 15 in the rest position, for example in the form of a loaded extraction rod by a return spring.

    Le moyen 11 de réception et d'application d'une bande adhésive se présente avantageusement sous forme d'une réglette guidée en coulissement dans le caisson 9, transversalement au sens de défilement des bandes 1 et 2 et pourvu d'une face externe munie de canaux d'aspiration 16 reliée à une chambre 19, qui est elle-même en communication avec une conduite d'aspiration 20 guidée de manière étanche dans l'une des extrémités de la réglette, du côté opposé à celui de l'extraction du caisson 9 et reliée à un moyen d'aspiration centrale non représenté. Ce dernier moyen peut être sous forme d'une pompe à vide reliée à la conduite 20 par l'intermédiaire d'un flexible.The means 11 for receiving and applying an adhesive strip is advantageously in the form of a guide strip in sliding in the box 9, transversely to the direction of travel of the bands 1 and 2 and provided with an external face provided with suction channels 16 connected to a chamber 19, which is itself in communication with a suction line 20 tightly guided in one of the ends of the strip, on the side opposite to that of the extraction of the casing 9 and connected to a central suction means not shown. This last way can be in the form of a vacuum pump connected to line 20 by through a hose.

    Près de son extrémité libre pénétrant dans la chambre 19 de la réglette formant le moyen 11, la conduite d'aspiration 20 est pourvue d'une bague d'arrêt empêchant toute extraction totale de ladite conduite 20 hors de la chambre 19. La réglette 20 peut donc être extraite, par un côté, du caisson 9 en vue de la mise en place sur sa face externe d'une bande adhésive 21, tout en évitant un démontage intempestif de ladite réglette. En outre, ce mode de réalisation permet le maintien immédiat de la bande adhésive 21 du fait de la dépression créée sur la face externe de la réglette, ce dans la position de la réglette hors du caisson 9.Near its free end entering chamber 19 of the strip forming the means 11, the suction line 20 is provided with a stop ring preventing any total extraction of said pipe 20 from chamber 19. The strip 20 can therefore be extracted from one side of the box 9 with a view to placing an adhesive strip 21 on its external face, while avoiding untimely disassembly of said strip. Furthermore, this embodiment allows immediate maintenance of the adhesive strip 21 due to the depression created on the external face of the strip, this in the position of the strip outside the box 9.

    Selon une autre caractéristique de l'invention, les moyens 11 formés par les réglettes sont déplaçables en direction des bandes 1 et 2, en position de service des châssis pivotants 6, chacun par l'intermédiaire d'un vérin 22 et sont rappelés en position de repos (représentée à la figure 2) par l'intermédiaire d'un organe 23 de rappel en position de repos, par exemple sous forme d'une tige d'extraction chargée par un ressort de rappel.According to another characteristic of the invention, the means 11 formed by the strips are movable towards the bands 1 and 2, in operating position of the pivoting frames 6, each via a cylinder 22 and are returned to the rest position (shown in Figure 2) by via a member 23 for resting in the rest position, for example in the form of an extraction rod loaded by a return spring.

    Chaque moyen 7 de guidage et de maintien provisoire des bandes 1 et 2 est constitué par une plaque rigide comportant au moins une ouverture 7' de passage des parties 10, 10' du dispositif de coupe ou des moyens 11 et de section légèrement supérieure à celle de cesdits dispositif et moyen. Les parties 10, 10' du dispositif de coupe et les moyens 11 de réception et d'application d'une bande adhésive 21 peuvent, lorsqu'ils sont déplacés devant les ouvertures 7' des moyens 7, coopérer respectivement pour la coupe des bandes 1 et 2 et pour le raccordement bout à bout de ces bandes.Each means 7 for guiding and temporarily holding the bands 1 and 2 consists of a rigid plate comprising at least one opening 7 'for passage of parts 10, 10' of the cutting device or means 11 and of section slightly greater than that of these said devices and average. The parts 10, 10 ′ of the cutting device and the means 11 for receiving and applying an adhesive strip 21 can, when they are moved in front of the openings 7 'of the means 7, cooperate respectively for cutting strips 1 and 2 and for the end-to-end connection of these bands.

    Les plaques formant les moyens 7 sont avantageusement pourvues, de part et d'autre des ouvertures 7' et sur toute la largeur de guidage des bandes 1 et 2 de rainures d'aspiration (non représentées) reliées à deux chambres d'aspiration, non représentées chaque chambre étant elle-même reliée individuellement à un moyen d'aspiration centrale. La prévision de telles rainures d'aspiration permet un placage efficace des bandes 1 et 2 contre les moyens 7 et un maintien des parties coupées desdites bandes après la coupe. Il suffira alors, après suppression de la dépression dans la chambre concernée, à savoir celle relative à l'extrémité de la nouvelle bande et celle relative à la partie de la bande finissante provenant de la bobine, de retirer les extrémités de bandes finissante 1 et nouvelle 2 concernées d'entre les moyens 7 pour ne plus disposer que des deux extrémités de bandes aboutées à raccorder.The plates forming the means 7 are advantageously provided on either side with openings 7 'and over the entire width of guiding the connected strips 1 and 2 of suction grooves (not shown) with two suction chambers, not shown, each chamber being itself individually connected to a central suction means. The provision of such suction grooves allows effective plating of bands 1 and 2 against the means 7 and maintaining cut parts said bands after cutting. It will then suffice, after removing the depression in the chamber concerned, namely that relating to the end of the new strip and that relating to the part of the ending strip from the spool, remove the ends of the finishing strip 1 and new 2 concerned of the means 7 to have more than two ends of butted strips to be connected.

    Un déplacement consécutif des caissons 9 amenant les moyens 11 avec les bandes adhésives 21 devant les ouvertures 7' permettra alors le déclenchement de l'opération de raccordement proprement dite qui est effectué par actionnement des vérins 22 correspondants. Il s'ensuit que les bandes adhésives 21 sont serrées, de part et d'autre du joint, sur les extrémités des bandes 1 et 2. A la fin de l'actionnement des vérins 22, les moyens 11 sont automatiquement ramenés dans leur position de départ et la nouvelle bande 2 peut être entraínée vers une machine en aval.A consecutive displacement of the boxes 9 bringing the means 11 with the adhesive strips 21 in front of the openings 7 ′ will then allow the initiation of the actual connection operation which is performed by actuating the corresponding cylinders 22. It follows that the adhesive strips 21 are tightened, on either side of the joint, on the ends of the bands 1 and 2. At the end of the actuation of the jacks 22, the means 11 are automatically returned to their starting position and the new strip 2 can be driven to a machine downstream.

    Ainsi, il est possible, par déplacement simultané des caissons 9 d'amener successivement le couteau 10 et le contre-couteau 10' du dispositif de coupe, puis les moyens 11 de réception et d'application d'une bande adhésive 21 devant les ouvertures 7' des moyens 7 de guidage et de maintien provisoire des bandes 1 et 2 et ensuite, après application intime desdits éléments contre les bandes 1 et 2 dans le sens de pincement de celles-ci, de réaliser la coupe simultanée desdites bandes 1 et 2 et après cette coupe d'effectuer le raccordement bout à bout.Thus, it is possible, by simultaneous displacement of the boxes 9 successively bring the knife 10 and the counter knife 10 'from the device cutting, then the means 11 for receiving and applying a strip adhesive 21 in front of the openings 7 'of the means 7 for guiding and provisional maintenance of bands 1 and 2 and then, after intimate application of said elements against strips 1 and 2 in the pinching direction of these, to carry out the simultaneous cutting of said strips 1 and 2 and after this cut to make the butt connection.

    Les parties de bandes non utilisées, à savoir le bout de la nouvelle bande 2 serrée dans le dispositif de pinçage 14, ainsi que le bout de bande finissante 1 de la bobine finissante peuvent être retirées respectivement manuellement par traction sur ce bout de bande après suppression de la dépression correspondante dans le moyen 7 et après ouverture du dispositif de pinçage 14 et par un actionnement de la bobine finissante dans le sens d'un enroulement de cette dernière.The unused strip parts, i.e. the end of the new strip 2 tightened in the clamping device 14, as well as the end of finishing tape 1 of the finishing reel can be removed respectively manually by pulling on this end of the strip after suppression of the corresponding depression in means 7 and after opening of the clamping device 14 and by actuation of the coil ending in the direction of a winding of the latter.

    Les moyens d'aspiration pour le maintien des bandes adhésives 21 ainsi que des bandes 1 et 2 contre les faces internes des moyens 7 sont de type connus et ne nécessitent pas une description plus détaillée. De préférence, les rainures d'aspiration peuvent être disposées par groupes symétriques par rapport à l'axe longitudinal des bandes 1 et 2 et être reliées à des chambres à pression négative commandées par paires. De manière connue, chaque chambre à pression négative peut être raccordée à un moyen central d'aspiration par l'intermédiaire de vannes à commande manuelle. Une telle disposition est également connue de l'homme du métier et ne nécessite pas non plus une description plus détaillée.Suction means for holding the adhesive tapes 21 as well as strips 1 and 2 against the internal faces of the means 7 are of known types and do not require a more detailed description. Of preferably the suction grooves can be arranged in groups symmetrical with respect to the longitudinal axis of bands 1 and 2 and be connected to negative pressure chambers controlled in pairs. So known, each negative pressure chamber can be connected to a central suction means via control valves manual. Such an arrangement is also known to those skilled in the art nor does it require a more detailed description.

    Les deux ensembles opposés pivotants 6 de préparation, de coupe et de raccordement des bandes finissante 1 et nouvelle 2, munis chacun d'un moyen 7 de guidage et de maintien provisoire desdites bandes, sont préférentiellement disposés dans un bâti 8 fermé et muni d'une partie frontale fermée par des portes coulissantes ou battantes, non représentées en détail, la partie supérieure de la machine, au-dessus des ensembles 6 étant munie de couvercles rabattables 23.The two opposite pivoting assemblies 6 for preparation, cutting and connecting the finishing strips 1 and new 2, fitted each of a means 7 for guiding and temporarily holding said strips, are preferably arranged in a closed frame 8 and provided with a part front closed by sliding or hinged doors, not shown in detail, the upper part of the machine, above the sets 6 being fitted with hinged covers 23.

    Les portes frontales permettent un accès, notamment aux bobines à dérouler et à l'accumulateur de bandes 4, alors que les couvercles rabattables 23 permettent, après ouverture, un pivotement des ensembles 6 dans une position de préparation pour une nouvelle bande 2, comme représentée à la figure 1 des dessins annexés.Front doors provide access, particularly to reels to unwind and to the tape accumulator 4, while the covers folding 23 allow, after opening, pivoting of the assemblies 6 in a prepared position for a new strip 2, like shown in Figure 1 of the accompanying drawings.

    Le mode de réalisation préférentiel représenté à la figure 1 prévoit une constitution dans laquelle la machine à dérouler se présente comme une machine relativement basse dans laquelle les bobines sont disposées dans un même niveau horizontal et la coupe et le raccordement s'effectuent dans une position verticale des bandes. Toutefois, il peut parfaitement être envisagé que la coupe des bandes s'effectue dans une position horizontale et que les bobines soient disposées verticalement l'une au-dessus de l'autre avec interposition du dispositif de coupe et de raccordement.The preferred embodiment shown in Figure 1 provides a constitution in which the unrolling machine is presented like a relatively low machine in which the coils are arranged in the same horizontal level and the cut and the connection take place in a vertical position of the bands. However, it can perfectly be considered that the cutting of the strips is carried out in a horizontal position and the coils are arranged vertically one above the other with interposition of the cutting device and connection.

    Grâce à l'invention, il est possible de réaliser une machine à dérouler permettant un déroulage de deux bobines et leur raccordement bout à bout, tout en évitant les défauts de fonctionnement générés par la courbure des bandes et par les bandes d'adhésifs aboutissant généralement à la production d'un effet "curling".Thanks to the invention, it is possible to make a unwind allowing two coils to be unwound and connected end to end, while avoiding malfunctions generated by the curvature of the strips and by the strips of adhesives generally leading to the production of a "curling" effect.

    En outre, le raccordement obtenu est particulièrement fiable.In addition, the connection obtained is particularly reliable.

    Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without leaving for as much of the scope of protection of the invention.
