Description

La présente invention concerne le domaine des machines à enrouler des matières en bande pour la réalisation de bobines et a pour objet un dispositif de coupe et d'application du début de bande d'une nouvelle bobine sur un mandrin d'un enrouleur.The present invention relates to the field of machines for winding strip material for making reels and relates to a device for cutting and applying the start of strip from a new reel to a mandrel of a winder.

L'enroulement de bandes au moyen de machines à enrouler cause généralement le problème, d'une part, de la coupe de la bande et, d'autre part, de l'application correcte de l'extrémité de la bande sur le mandrin après la coupe.The winding of strips by means of winding machines generally causes the problem, on the one hand, of the cutting of the strip and, on the other hand, of the correct application of the end of the strip on the mandrel after the cup.

A cet effet, il peut être proposé de réaliser la coupe pendant le défilement de la bande suivant un principe appelé coupe à la volée, dans lequel un couteau est projeté dans le parcours de la bande et l'extrémité coupée de la bande est projetée sur un mandrin préalablement encollé ou muni d'une ou de plusieurs bandes adhésives de réception de ladite extrémité, qui est serrée en outre sur ledit mandrin par la bande au cours de son enroulement.For this purpose, it may be proposed to make the cut during the running of the strip according to a principle called cutting on the fly, in which a knife is projected in the path of the strip and the cut end of the strip is projected onto a mandrel previously glued or provided with one or more adhesive strips for receiving said end, which is further clamped on said mandrel by the strip during its winding.

Une telle coupe pendant le défilement de la bande permet un rendement important, pratiquement sans ralentissement de la vitesse de défilement de la bande lors de la coupe.Such a cut during the running of the strip allows a high yield, practically without slowing down the running speed of the strip during cutting.

Cependant, dans le cas de l'enroulement de bandes en des matières relativement friables, une coupe à la volée compromet la bonne tenue de l'extrémité coupée qui peut éventuellement être endommagée sur une longueur relativement importante, voire avoir tendance à provoquer une cassure de la bande à une certaine distance de l'endroit de la coupe, ce qui peut entraîner un mauvais enroulement, voire un défaut d'enroulement, la bande n'étant même plus appliquée sur le nouveau mandrin ou présentant un rabat.However, in the case of the winding of strips of relatively friable materials, a cut on the fly compromises the good behavior of the cut end which can possibly be damaged over a relatively large length, or even have a tendency to cause breakage. the strip at a certain distance from the place of the cut, which can cause a bad winding, or even a winding defect, the strip being no longer even applied to the new mandrel or having a flap.

Il a également été proposé de réaliser la coupe, après un arrêt de l'enroulement de la bobine pleine, manuellement, la bande à enrouler étant stockée dans un accumulateur. Dans un tel cas, la coupe est réalisée manuellement par deux opérateurs, dont l'un tient l'extrémité de la bande coupée pendant que l'autre encolle le nouveau mandrin, puis applique ladite extrémité sur ledit nouveau mandrin, dont le démarrage est commandé par l'un des deux opérateurs. Un tel mode de réalisation nécessite cependant une intervention des opérateurs dans une machine en marche, ce qui entraîne forcément un risque d'accident. D'autre part, du fait que l'intervention est effectuée manuellement, il est nécessaire de prévoir un accumulateur de taille importante, notamment dans le cas d'enroulement à des vitesses élevées, pour pallier tout risque de dépassement du temps de coupe et de raccordement imparti. En outre, le raccordement du début de bande sur le nouveau mandrin est forcément réalisé de manière aléatoire, du fait que cette opération s'effectue relativement précipitamment.It has also been proposed to make the cut, after stopping the winding of the full reel, manually, the strip to be wound up being stored in an accumulator. In such a case, the cut is carried out manually by two operators, one of whom holds the end of the cut strip while the other glues the new mandrel, then applies said end to said new mandrel, the start of which is controlled by one of the two operators. However, such an embodiment requires intervention by the operators in a machine in operation, which necessarily entails a risk of accident. On the other hand, since the intervention is carried out manually, it is necessary to provide a large accumulator, in particular in the case of winding at high speeds, to offset any risk of exceeding the cutting time and connection outsourced. In addition, the connection of the strip start on the new mandrel is necessarily carried out randomly, because this operation is carried out relatively precipitously.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif de coupe et d'application du début de bande d'une nouvelle bobine sur un mandrin d'un enrouleur, essentiellement constitué par un moyen de coupe coopérant avec un moyen de serrage de la bande et par un moyen d'application d'une bande adhésive ou analogue sur l'extrémité coupée de la bande et de pression et d'application de cette dernière et de la bande adhésive sur le mandrin de la nouvelle bobine, caractérisé en ce que le moyen de coupe se présente sous forme d'un caisson de logement et de guidage d'un couteau déplaçable dans une fente, ledit caisson étant monté sur un châssis de guidage de la bande, disposé avec possibilité de basculement, sous l'action d'un vérin, dans le châssis de l'enrouleur, ledit caisson étant déplaçable transversalement à la direction de défilement de la bande, sa face portant la fente étant tournée vers ladite bande.It relates, in fact, to a device for cutting and applying the start of the strip from a new reel to a mandrel of a reel, essentially constituted by a cutting means cooperating with a means for tightening the strip and by means of applying an adhesive strip or the like to the cut end of the strip and pressing and applying the latter and the adhesive strip to the mandrel of the new spool, characterized in that the means cutting is in the form of a housing and guiding a knife movable in a slot, said box being mounted on a frame for guiding the strip, arranged with the possibility of tilting, under the action of a jack, in the frame of the reel, said box being movable transversely to the direction of travel of the strip, its face carrying the slot being turned towards said strip.

  • Figure 1 is a side elevational view of the device according to the invention mounted on a reel;

Le dispositif de coupe et d'application du début de bande d'une nouvelle bobine sur un mandrin 1 d'un enrouleur 2 est essentiellement constitué par un moyen de coupe 3 coopérant avec un moyen 4 de serrage de la bande et par un moyen 5 d'application d'une bande adhésive ou analogue 6 sur l'extrémité coupée de la bande et de pression et d'application de cette dernière et de la bande adhésive sur le mandrin 1 de la nouvelle bobine.The device for cutting and applying the start of the strip of a new reel to a mandrel 1 of a reel 2 is essentially constituted by a cutting means 3 cooperating with a means 4 for tightening the strip and by a means 5 applying an adhesive strip or the like 6 to the cut end of the strip and pressing and applying the latter and the adhesive strip to the mandrel 1 of the new coil.

Le moyen de coupe 3 (figures 2 à 4) se présente sous forme d'un caisson 7 de logement et de guidage d'un couteau 8 déplaçable dans une fente 8', ledit caisson étant monté sur un châssis 9 de guidage de la bande, disposé avec possibilité de basculement, sous l'action d'un vérin 10, dans le châssis 11 de l'enrouleur 2, ledit caisson 7 étant déplaçable transversalement à la direction de défilement de la bande, sa face portant la fente 8' étant tournée vers ladite bande.The cutting means 3 (Figures 2 to 4) is in the form of a box 7 housing and guiding a knife 8 movable in a slot 8 ', said box being mounted on a frame 9 for guiding the strip , arranged with the possibility of tilting, under the action of a jack 10, in the chassis 11 of the reel 2, said box 7 being movable transversely to the direction of movement of the strip, its face carrying the slot 8 'being turned towards said strip.

Le caisson 7 est monté par ses extrémités dans le châssis 9 au moyen de coulisseaux de guidage d'extrémité 12, coopérant par des roulettes de guidage 13 avec des rails de guidage dudit châssis 9 et est actionné en déplacement, transversalement à la direction de défilement de la bande, au moyen de vérins 14 s'appuyant sur la face dudit caisson 7 opposée à celle de guidage du couteau 8, lesdits vérins 14 étant montés sur une barre de support 15 du châssis 9.The box 7 is mounted at its ends in the chassis 9 by means of end guide slides 12, cooperating by guide rollers 13 with guide rails of said chassis 9 and is actuated in displacement, transverse to the direction of travel. of the strip, by means of jacks 14 resting on the face of said box 7 opposite that of the knife 8 guide, said jacks 14 being mounted on a support bar 15 of the chassis 9.

Le couteau 8 est monté sur un chariot 16 guidé, par l'intermédiaire de roulettes 17, dans un rail 18 ménagé dans le caisson 7 de part et d'autre de la fente 8', ledit chariot 16 étant actionné en déplacement longitudinal dans le caisson 7 au moyen d'un vérin sans tige 19. Un tel mode de montage du chariot 16 permet un guidage parfait de ce dernier, sans risque de déviation du couteau 8, le chariot 16 étant relié directement au piston du vérin sans tige 19. En effet, un tel vérin assure une précision parfaite du déplacement du chariot 16 et donc du couteau 8 avec une installation de puissance relativement faible.The knife 8 is mounted on a carriage 16 guided, by means of rollers 17, in a rail 18 formed in the box 7 on either side of the slot 8 ', said carriage 16 being actuated in longitudinal displacement in the box 7 by means of a rodless cylinder 19. Such a method of mounting the carriage 16 allows perfect guidance of the latter, without risk of deflection of the knife 8, the carriage 16 being connected directly to the piston of the rodless cylinder 19. Indeed, such a jack ensures perfect precision of the movement of the carriage 16 and therefore of the knife 8 with a relatively low power installation.

En outre, le caisson 7 est pourvu de deux caches d'extrémité 8'', montés de manière réglable en position, au-dessus de la fente 8' et destinés à recouvrir le couteau 8 dans ses positions extrêmes.In addition, the box 7 is provided with two end caps 8 '', mounted in an adjustable position, above the slot 8 'and intended to cover the knife 8 in its extreme positions.

Le moyen 4 de serrage de la bande coopérant avec le moyen de coupe 3 est constitué sous forme d'une plaque de contre-partie transversale 20 pourvue d'une fente 21 destinée à coopérer avec l'extrémité du couteau 8 du moyen de coupe 3, ladite plaque 20 étant montée à l'extrémité de bras 22, pivotant autour de l'axe des disques 23 de support des arbres porte-bobine 24 de l'enrouleur et actionnés en pivotement au moyen de vérins synchronisés 25.The means 4 for tightening the strip cooperating with the cutting means 3 is constituted in the form of a transverse counterpart plate 20 provided with a slot 21 intended to cooperate with the end of the knife 8 of the cutting means 3 , said plate 20 being mounted at the end of the arm 22, pivoting about the axis of the discs 23 for supporting the reel-carrying shafts 24 of the reel and actuated in pivoting by means of synchronized jacks 25.

Le châssis 9, pouvant être basculé sous l'action du vérin 10 et muni de rouleaux 9' de renvoi de la bande, est monté pivotant autour de l'axe 9'' de l'un de ces rouleaux de renvoi 9' entre une position escamotée de préparation du moyen 5 d'application de la bande adhésive ou analogue 6, présentant le moyen de coupe 3 dans une position horizontale, le couteau 8 tourné vers le haut, et une position de coupe et d'application de l'extrémité de bande coupée sensiblement à la verticale, dans un plan tangent à la génératrice décrite par les axes des arbres porte-bobine 24 montés sur les disques 23 de l'enrouleur 2 (figure 2).The frame 9, which can be tilted under the action of the jack 10 and provided with rollers 9 'for returning the strip, is pivotally mounted around the axis 9' 'of one of these return rollers 9' between a retracted position for preparing the means 5 for applying the adhesive tape or the like 6, having the cutting means 3 in a horizontal position, the knife 8 facing upwards, and a position for cutting and applying the end of strip cut substantially vertically, in a plane tangent to the generator described by the axes of the reel-holder shafts 24 mounted on the discs 23 of the reel 2 (FIG. 2).

Selon une caractéristique de l'invention, l'enrouleur comporte avantageusement un nombre de moyens de serrage 4 égal à celui des arbres porte-bobine 24. Le montage des bras pivotants 22 sur l'axe des disques 23 permet, lors de l'opération de coupe de la bande, d'amener la plaque de contre-partie transversale 20 du moyen 4 de serrage de la bande dans une position parfaitement tangentielle au plan de défilement de ladite bande, en face du moyen de coupe 3.According to a characteristic of the invention, the reel advantageously comprises a number of clamping means 4 equal to that of the spool-holder shafts 24. The mounting of the pivoting arms 22 on the axis of the discs 23 allows, during the operation for cutting the strip, for bringing the transverse counterpart plate 20 of the strip tightening means 4 into a position which is perfectly tangential to the running plane of said strip, opposite the cutting means 3.

Conformément à une autre caractéristique de l'invention et comme le montre la figure 2, le châssis 9 est pourvu, en outre, d'un moyen 26 de blocage de la bande pendant l'opération de coupe et d'application sur le mandrin de la nouvelle bobine, ce moyen 26 coopérant avec un rouleau de renvoi 9'.In accordance with another characteristic of the invention and as shown in FIG. 2, the chassis 9 is further provided with means 26 for blocking the strip during the cutting and application operation on the mandrel. the new coil, this means 26 cooperating with a deflection roller 9 '.

Le moyen de blocage 26 est constitué, de préférence, par une barre transversale 27 montée de manière déplaçable dans un plan passant par l'axe du rouleau 9' correspondant, par l'intermédiaire d'au moins un vérin d'actionnement 28, et par une traverse 29 du châssis 9 supportant lesdits vérin 28 et barre transversale 27. Ainsi, par actionnement du ou des vérins 28, la barre transversale 27 est appliquée à force contre le rouleau 9' correspondant et réalise un blocage de la bande en défilement.The locking means 26 preferably consists of a transverse bar 27 mounted so as to be displaceable in a plane passing through the axis of the corresponding roller 9 ′, by means of at least one actuating cylinder 28, and by a cross member 29 of the frame 9 supporting said cylinders 28 and transverse bar 27. Thus, by actuation of the cylinder or cylinders 28, the transverse bar 27 is applied by force against the roller 9 'corresponding and performs a blocking of the strip in movement.

Selon une autre caractéristique de l'invention, non représentée aux dessins annexés, le caisson 7 de logement et de guidage du couteau 8 du moyen de coupe 3 est pourvu de moyens de centrage et de détection de fin de course coopérant avec des moyens de forme correspondante prévus sur les extrémités des bras 22 de support de la plaque de contre-partie 20 formant le moyen de serrage 4. Les moyens de centrage et de détection peuvent avantageusement être constitués sous forme de perçages tronconiques débouchant à leur base de section restreinte sur un contact de fin de course et les moyens de forme correspondante, prévus sur les extrémités des bras 22 de support de la plaque de contre-partie 20, présentent alors une forme de pige conique, dont l'extrémité coopère en fin de course de centrage avec le contact de fin de course des moyens prévus sur le caisson 7.According to another characteristic of the invention, not shown in the accompanying drawings, the box 7 for housing and guiding the knife 8 of the cutting means 3 is provided with centering and end-of-stroke detection means cooperating with form means corresponding provided on the ends of the arms 22 for supporting the counterpart plate 20 forming the clamping means 4. The centering and detection means may advantageously be constituted in the form of frustoconical holes opening at their base of restricted section on a limit switch and the correspondingly shaped means, provided on the ends of the arms 22 for supporting the counterpart plate 20, then have a conical rod shape, the end of which cooperates at the end of the centering stroke with the limit switch contact of the means provided on the box 7.

Ce contact de fin de course est destiné, d'une part, à détecter la coopération entre le moyen de coupe 3 et le moyen de serrage 4 et, d'autre part, l'application effective de l'un contre l'autre afin d'autoriser la coupe de la bande par le couteau 8 monté sur le chariot 16 et actionné par le vérin sans tige 19.This limit switch is intended, on the one hand, to detect the cooperation between the cutting means 3 and the clamping means 4 and, on the other hand, the effective application of one against the other so authorize the cutting of the strip by the knife 8 mounted on the carriage 16 and actuated by the rodless cylinder 19.

Le moyen 5 d'application d'une bande adhésive ou analogue 6 sur l'extrémité coupée de la bande et de pression et d'application de cette dernière et de la bande adhésive sur le mandrin 1 de la nouvelle bobine est avantageusement constitué par un cylindre à dépression 31 (figures 2 et 5) présentant une bande perforée 32 de maintien par dépression de la bande adhésive 6 ou analogue, ledit cylindre à dépression 31 étant monté de manière pivotante dans le châssis basculant 9 au moyen de bras 33 actionnés par au moins un vérin 34.The means 5 for applying an adhesive strip or the like 6 on the cut end of the strip and for pressing and applying the latter and the adhesive strip to the mandrel 1 of the new reel is advantageously constituted by a vacuum cylinder 31 (FIGS. 2 and 5) having a perforated strip 32 for holding the adhesive strip 6 or the like by vacuum, said vacuum cylinder 31 being pivotally mounted in the tilting frame 9 by means of arms 33 actuated by minus one cylinder 34.

Selon une caractéristique de l'invention, le cylindre à dépression 31 est pourvu d'au moins un moyen d'indexage 35 consistant en une roulette 36 montée sur un levier pivotant 37 actionné par un vérin 38, prévu sur un bras 33, et coopérant avec des évidements 39 de forme correspondante prévus sur l'extrémité correspondante du cylindre à dépression 31 (figure 2).According to a characteristic of the invention, the vacuum cylinder 31 is provided with at least one indexing means 35 consisting of a roller 36 mounted on a pivoting lever 37 actuated by a jack 38, provided on an arm 33, and cooperating with recesses 39 of corresponding shape provided on the corresponding end of the vacuum cylinder 31 (Figure 2).

Les évidements 39 sont avantageusement au nombre de deux et sont disposés à une distance angulaire correspondant à la distance linéaire entre l'axe médian de la bande perforée 32 du cylindre à dépression 31, en position de coupe et d'application de la bande, et la fente 8' du caisson 7 du moyen de coupe 3. Ainsi, la bande adhésive ou analogue 6 peut être appliquée sur la bande perforée 32 du cylindre à dépression 31 dans une position d'indexage dudit cylindre 31 correspondant à la position d'application de l'extrémité de la bande coupée et de la bande adhésive sur le mandrin 1, puis ledit cylindre 31 est amené dans la seconde position d'indexage, dans laquelle il est maintenu par l'intermédiaire du vérin 38 amenant la roulette 36 par pivotement du levier 37 dans l'évidement 39 correspondant. Cette deuxième position d'indexage correspond à une position d'attente, dans laquelle la bande est coupée par le couteau 8 du moyen de coupe 3.The recesses 39 are advantageously two in number and are arranged at an angular distance corresponding to the linear distance between the median axis of the perforated strip 32 of the vacuum cylinder 31, in the cutting and applying position of the strip, and the slot 8 'of the box 7 of the cutting means 3. Thus, the adhesive strip or the like 6 can be applied to the perforated strip 32 of the vacuum cylinder 31 in an indexing position of said cylinder 31 corresponding to the application position from the end of the cut strip and the adhesive strip on the mandrel 1, then said cylinder 31 is brought into the second indexing position, in which it is held by means of the jack 38 bringing the caster 36 by pivoting lever 37 in the corresponding recess 39. This second indexing position corresponds to a waiting position, in which the strip is cut by the knife 8 of the cutting means 3.

Selon une autre caractéristique de l'invention et comme le montrent les figures 2 et 5 des dessins annexés, le caisson 7 du moyen de coupe 3 est avantageusement pourvu d'une plaque intermédiaire de guidage 40 montée de manière pivotante sur le caisson 7 et s'étendant en direction du cylindre à dépression 31 en recouvrant partiellement ce dernier en position de préparation du moyen 5 d'application de la bande adhésive ou analogue 6, ainsi qu'en position de coupe de la bande, cette plaque 40 se déplaçant, sous l'effet de la poussée du cylindre à dépression 31 en direction du mandrin 1 pendant la phase d'application de l'extrémité de la bande coupée et de la bande adhésive ou analogue 6 sur ledit mandrin 1 et étant rappelée en position par un ressort 41.According to another characteristic of the invention and as shown in Figures 2 and 5 of the accompanying drawings, the box 7 of the cutting means 3 is advantageously provided with an intermediate guide plate 40 pivotally mounted on the box 7 and s extending towards the vacuum cylinder 31 by partially covering the latter in the position for preparing the means 5 for applying the adhesive tape or the like 6, as well as in the tape cutting position, this plate 40 moving, under the effect of the vacuum cylinder thrust 31 in the direction of the mandrel 1 during the application phase of the end of the cut strip and of the adhesive strip or the like 6 on said mandrel 1 and being returned to position by a spring 41.

Lors de cette phase d'application, le cylindre à dépression 31 est déplacé contre le mandrin 1 par l'intermédiaire du ou des vérins 34 agissant sur les bras 33 de support, de manière à réaliser un pivotement de l'ensemble autour de son axe d'articulation.During this application phase, the vacuum cylinder 31 is moved against the mandrel 1 by means of the jack or jacks 34 acting on the support arms 33, so as to pivot the assembly around its axis. of articulation.

Une rotation de l'arbre porte-bobine 24 de support du mandrin 1 en sens inverse au sens d'enroulement aura pour effet de déplacer le cylindre 31 en rotation, de manière à l'amener dans une position correspondant à sa première position d'indexage, c'est-à-dire celle où la bande adhésive 6 est en regard du mandrin 1, et à réaliser une rotation supplémentaire dans ce sens, en vue d'une application totale de la bande adhésive sur le mandrin 1 par repassage.A rotation of the spool-holder shaft 24 supporting the mandrel 1 in the opposite direction to the winding direction will have the effect of moving the cylinder 31 in rotation, so as to bring it into a position corresponding to its first position of indexing, that is to say that where the adhesive strip 6 is facing the mandrel 1, and to perform an additional rotation in this direction, for a total application of the adhesive strip on the mandrel 1 by ironing.

Le dispositif conforme à l'invention fonctionne de la manière suivante :The device according to the invention operates as follows:

A la fin de l'enroulement d'une bobine pleine, les disques 23 de l'enrouleur 2 sont mis en rotation afin d'amener un nouveau mandrin 1 en position d'enroulement, comme représenté aux figures 1 et 2 des dessins annexés.At the end of the winding of a full reel, the discs 23 of the winder 2 are rotated in order to bring a new mandrel 1 into the winding position, as shown in Figures 1 and 2 of the accompanying drawings.

Pendant l'enroulement de la bobine précédente, un opérateur aura amené le cylindre à dépression 31, dans la position de préparation du châssis 9, c'est-à-dire en position pivotée de manière à présenter la fente 8' du couteau 8 tournée vers le haut, dans la première position d'indexage représentée à la figure 5 des dessins annexés, dans laquelle la bande perforée 32 est également tournée vers le haut et s'étend en prolongement de la plaque intermédiaire de guidage 40. Dans cette position, l'opérateur applique une bande adhésive 6 au-dessus des perforations de la bande 32 et déclenche l'aspiration à l'intérieur du cylindre 31, de sorte que ladite bande 6 est maintenue, puis il tourne ledit cylindre 31 jusqu'à amener celui-ci dans sa deuxième position d'indexage, dans laquelle la roulette 36 coopère avec le deuxième évidement 39.During the winding of the previous coil, an operator will have brought the vacuum cylinder 31, in the preparation position of the frame 9, that is to say in the pivoted position so as to present the slot 8 'of the knife 8 turned upwards, in the first indexing position shown in FIG. 5 of the accompanying drawings, in which the perforated strip 32 is also turned upwards and extends in extension of the intermediate guide plate 40. In this position, the operator applies an adhesive strip 6 above the perforations of the strip 32 and triggers the suction inside of the cylinder 31, so that the said strip 6 is held, then it turns the said cylinder 31 until it brings the latter into its second indexing position, in which the roller 36 cooperates with the second recess 39.

Le moyen 4 de serrage de la bande est pivoté, par l'intermédiaire des vérins 25, dans sa position de service, au-dessus du nouveau mandrin 1 et le châssis 9 de support du caisson 7 du moyen de coupe 3 est alors pivoté, sous l'action du vérin 10, en direction de la position de coupe et d'application de la bande sur le mandrin 1.The means 4 for tightening the strip is pivoted, via the jacks 25, in its operating position, above the new mandrel 1 and the chassis 9 for supporting the box 7 of the cutting means 3 is then pivoted, under the action of the jack 10, in the direction of the cutting position and application of the strip on the mandrel 1.

Simultanément, le caisson 7 est déplacé dans sa position définitive de service, dans laquelle ses moyens de centrage et de détection de fin de course coopèrent avec les moyens de forme correspondante prévus sur les extrémités des bras 22 de support de la plaque de contrepartie 20 formant le moyen de serrage 4 et l'enroulement de la bobine pleine est arrêté, de sorte que la bande est prête à être coupée par le couteau 8. Le contact ainsi détecté par les moyens correspondants du caisson 7 autorise, préalablement à la coupe, le déclenchement de la coupe sous tension de la bande et en empêchant tout défilement de celle-ci, la bande s'enroulant, pendant la coupe, de manière connue, sur un accumulateur 30 monté en amont de l'enrouleur 2. Un tel accumulateur 30 est connu en soi et son fonctionnement n'est pas décrit en détail.Simultaneously, the box 7 is moved to its final service position, in which its centering and end-of-travel detection means cooperate with the correspondingly shaped means provided on the ends of the arms 22 for supporting the counterpart plate 20 forming the clamping means 4 and the winding of the full reel is stopped, so that the strip is ready to be cut by the knife 8. The contact thus detected by the corresponding means of the box 7 authorizes, before cutting, the initiation of the cut under tension of the strip and preventing any run of the latter, the strip being wound, during cutting, in known manner, on an accumulator 30 mounted upstream of the reel 2. Such an accumulator 30 is known per se and its operation is not described in detail.

Le couteau est alors déplacé transversalement à la bande de matière à couper par actionnement de son vérin 19 entraînant son chariot de support 16, en étant guidé, d'une part, dans la fente 8 du caisson 7 et, d'autre part, dans la fente 21 de la plaque de contre-partie transversale 20 du moyen de serrage 4.The knife is then moved transversely to the strip of material to be cut by actuation of its jack 19 driving its support carriage 16, being guided, on the one hand, in the slot 8 of the box 7 and, on the other hand, in the slot 21 of the transverse counterpart plate 20 of the clamping means 4.

Ensuite, le cylindre à dépression 31 est pivoté, par actionnement de son ou de ses vérins 34, contre le nouveau mandrin 1, afin de serrer la bande coupée contre ce dernier, puis l'arbre porte-bobine 24 est mis en rotation lente en sens inverse au sens d'enroulement en vue d'amener le cylindre à dépression 31 avec le début de bande et la bande adhésive 6 en face du nouveau mandrin 1 et de les appliquer sur ce dernier par poursuite de ce mouvement de rotation en vue d'une application totale de la bande 6 sur le mandrin 1, cette application étant affermie par un mouvement consécutif en va et vient de rotation, de manière à réaliser un repassage de l'extrémité ainsi réalisée sur le nouveau mandrin 1. L'enroulement de la nouvelle bobine peut alors débuter, le moyen de blocage 26 étant débloqué, le cylindre à dépression 31 pivotant dans sa position de départ, le caisson 7 étant également ramené dans sa position de départ, avant basculement, également en position de départ, du châssis 9 et le moyen de serrage 4 basculant dans sa position de départ par actionnement des bras 22 au moyen des vérins 25.Then, the vacuum cylinder 31 is pivoted, by actuation of its or its jacks 34, against the new mandrel 1, in order to clamp the cut strip against the latter, then the spool-holder shaft 24 is slowly rotated in the opposite direction to the winding direction in order to bring the vacuum cylinder 31 with the start of strip and the adhesive strip 6 in front of the new mandrel 1 and to apply them on the latter by continuing this rotational movement for a total application of the strip 6 on the mandrel 1, this application being strengthened by a consecutive movement back and forth in rotation, so as to iron the end thus produced on the new mandrel 1. The winding of the new coil can then begin, the locking means 26 being released, the vacuum cylinder 31 pivoting in its starting position, the box 7 also being returned to its starting position, before tilting, also in the starting position, of the chassis 9 and the clamping means 4 tilting in its starting position by actuation t of arms 22 by means of jacks 25.

Grâce à l'invention il est possible de réaliser un enrouleur dans lequel la coupe de la bande et l'application de son début sur un mandrin d'une nouvelle bobine sont effectuées de manière parfaite, c'est-à-dire sans détérioration de la bande au niveau de la coupe et sans risque de formation de plis du début de bande lors de l'enroulement. Un tel enrouleur est particulièrement adapté à l'enroulement de matières cassantes.Thanks to the invention it is possible to produce a reel in which the cutting of the strip and the application of its beginning on a mandrel of a new reel are carried out in a perfect manner, that is to say without deterioration of the strip at the level of the cut and without the risk of the folds forming from the start of the strip during winding. Such a reel is particularly suitable for winding brittle materials.

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 embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
