Description

La présente invention concerne un dispositif de positionnement d'une plaque de découpe sur un cylindre à fixation magnétique.The present invention relates to a device for positioning a cutting plate on a cylinder to magnetic fixation.

La découpe des flans de carton fait principalement appel à deux techniques essentielles à savoir le procédé dit SK (« Single Knife ») dans lequel le flan de carton est admis entre deux cylindres associés, à savoir un cylindre de découpe et un cylindre contrepartie, et le procédé dit TK (« Twin knife ») dans lequel le flan de carton est admis entre deux cylindres de découpe dont les empreintes sont rigoureusement repérées l'une par rapport à l'autre.The cutting of cardboard blanks is mainly done call to two essential techniques namely the process said SK ("Single Knife") in which the carton blank is admitted between two associated cylinders, namely a cutting cylinder and a counterpart cylinder, and the TK process ("Twin knife") in which the blank of cardboard is admitted between two cutting cylinders whose footprints are rigorously pinpointed relative to each other to the other.

Ces différentes techniques sont utilisées conjointement soit avec des cylindres massifs monoblocs, soit avec des cylindres sur lesquels des segments sont rapportés. On sait que ces deux types de cylindres sont d'un coût relativement élevé et c'est pourquoi on a proposé de faire appel à des plaques qui sont recouvertes l'une et l'autre des empreintes nécessaires à la formation de la découpe ou du marquage de pli, et qui sont fixées sur un cylindre support par divers moyens de fixation.These different techniques are used together with solid monoblock cylinders, with cylinders on which segments are reported. We know that these two types of cylinder are relatively high cost and that's why we have proposed to use plates that are covered both of the fingerprints necessary for the formation of the cut or the marking of fold, and which are fixed on a support cylinder by various means of fixation.

Un premier moyen consiste, après repérage et positionnement, à souder la plaque sur le cylindre support par ses deux extrémités. Une telle technique présente cependant l'inconvénient de nécessiter des moyens mécaniques importants pour assurer la tension et une application parfaite de la plaque sur le cylindre support.A first means consists, after identification and positioning, to weld the plate on the cylinder support by its two ends. Such a technique However, it has the disadvantage of requiring important mechanical means to ensure the tension and a perfect application of the plate on the cylinder support.

Un second moyen, dit « fixation de type ARK » consiste à disposer, sur l'une des faces de la plaque, à chacune des extrémités longitudinales de celle-ci, un élément de maintien parallélépipédique, chaque élément de maintien venant s'encastrer dans une rainure longitudinale prévue en surface du cylindre. Dans un tel dispositif la tension est assurée par un système de coins qui tend à rapprocher l'un de l'autre les deux éléments parallélépipédiques. Un inconvénient de ce type de technique est qu'il nécessite pour être efficace une tension qui est constante sur la plaque et qui est également répartie sur le pourtour du cylindre.A second means, called "ARK type fixation" consists in arranging, on one of the faces of the plate, each of the longitudinal ends thereof, a parallelepiped holding element, each element of holding coming into a groove longitudinal projection on the surface of the cylinder. In such a device the voltage is ensured by a system of corners which tends to bring the two elements closer together cuboid. A disadvantage of this type of technique is that it requires to be effective a voltage that is constant on the plate and that is evenly distributed around the cylinder.

Un troisième moyen de fixation de la plaque sur le cylindre support consiste à faire appel à des moyens magnétiques qui sont essentiellement constitués de barreaux aimantés qui sont encastrés dans des rainures longitudinales prévues en périphérie du cylindre support, voir, par éxample, DE-U-29815866.A third means of fixing the plate on the cylinder support is to use means magnetic devices which consist essentially of magnetic bars that are embedded in grooves longitudinal projections on the periphery of the support cylinder, see, for example, DE-U-29815866.

Les dispositifs de maintien de plaque de ce dernier type sont peu onéreux et faciles à mettre en oeuvre. Un inconvénient cependant de cette technique est que, une fois la plaque positionnée sur le cylindre, il n'est plus possible de procéder à une correction, si petite soit elle, de son positionnement. Or un positionnement précis, notamment lorsque la découpe est réalisée par la technique TK, est essentiel au bon fonctionnement du système. C'est pourquoi un tel type de fixation n'est pas utilisé lorsqu'un positionnement extrêmement précis de la plaque sur le cylindre se révèle nécessaire. The plate holding devices of the latter type are inexpensive and easy to implement. A disadvantage however of this technique is that, a Once the plate is positioned on the cylinder, it is no longer possible to make a correction, however small she, from her positioning. But a precise positioning, especially when the cut is made by the TK technique, is essential for the proper functioning of the system. That is why such a type of fixation is not used when extremely accurate positioning of the plate on the cylinder is needed.

En ce qui concerne le positionnement des empreintes de découpe dans le sens de l'axe longitudinal du cylindre, on sait que les machines de découpe sont pourvues de moyens permettant d'assurer un tel déplacement des cylindres support de façon à compenser tout décalage dans le sens longitudinal. De même les cylindres support de plaques sont pourvus de moyens permettant d'assurer une compensation angulaire d'un cylindre par rapport à l'autre, notamment en agissant sur des engrenages assurant leur entraínement.Regarding the positioning of fingerprints in the direction of the longitudinal axis of the cylinder, we know that the cutting machines are provided with means to ensure such displacement of the support cylinders so as to compensate any offset in the longitudinal direction. Similarly, plates support cylinders are provided with means to ensure an angular compensation of a cylinder with respect to the other, in particular by acting on gears ensuring their training.

La présente invention a pour but de proposer un moyen permettant d'assurer à la fois la correction de l'orientation d'une plaque de découpe dans le sens transversal au cylindre et la correction du positionnement angulaire relatif de deux cylindres associés.The present invention aims to propose a means of ensuring both the correction of the orientation of a cutting plate in the direction transverse to the cylinder and the correction of relative angular positioning of two cylinders associates.

La présente invention a ainsi pour objet un dispositif selon la revendication 1.The present invention thus relates to a device according to claim 1.

Dans un premier mode de mise en oeuvre de l'invention le dispositif de positionnement comportera un élément de centrage fixe par rapport au cylindre, de façon à assurer une orientation du grand axe de la plaque par rapport à l'axe transversal du cylindre.In a first mode of implementation of the invention the positioning device will include a centering element fixed relative to the cylinder, to ensure orientation of the major axis of the plate relative to the transverse axis of the cylinder.

La présente invention permet également, lorsque les deux éléments de centrage sont des éléments mobiles dont le déplacement s'effectue suivant l'axe transversal du cylindre, de déplacer la plaque parallèlement à elle-même, ce qui revient à la faire tourner autour du cylindre si bien que l'on assure ainsi un décalage angulaire de cette plaque par rapport à la plaque disposée sur le cylindre associé.The present invention also allows, when the two centering elements are moving elements of which the displacement takes place along the transverse axis of the cylinder, to move the plate parallel to itself, which amounts to turning it around the cylinder so that one ensures thus an offset angular of this plate with respect to the plate disposed on the associated cylinder.

Préférentiellement les éléments de centrage seront constitués de pions et les éléments complémentaires seront constitués d'orifices prévus dans la plaque. Les pions seront de préférence constitués d'éléments cylindriques de section droite circulaire. Dans le cas où l'un des pions est fixe par rapport au cylindre, l'orifice correspondant au pion mobile pourra avoir une forme allongée dans le sens longitudinal de l'axe du cylindre, son autre dimension correspondant rigoureusement au diamètre externe du pion.Preferably, the centering elements will be made up of pions and the complementary elements will consist of orifices provided in the plate. The pions will preferably consist of elements cylindrical of circular cross section. In the case where one of the pins is fixed relative to the cylinder, the orifice corresponding to the movable pin may have a elongate shape in the longitudinal direction of the axis of the cylinder, its other corresponding dimension rigorously to the outer diameter of the pin.

Les moyens de commande pourront avantageusement être constitués par un levier monté pivotant autour d'un axe solidaire du cylindre dont une extrémité comportera un élément de repérage solidaire de l'autre côté de la plaque et qui sera apte à effectuer un déplacement angulaire sous l'action de moyens de commande disposés à l'autre extrémité du levier.The control means can advantageously be constituted by a lever pivoted about an axis integral with the cylinder, one end of which will have a solidarity marking element on the other side of the plate and who will be able to make a displacement angular under the action of control means arranged to the other end of the lever.

Les moyens de commande peuvent être constitués par une vis pourvue d'un bouton de commande comportant un vernier de réglage.The control means can be constituted by a screw provided with a control button comprising a vernier adjustment.

Les moyens de commande pourront également être constitués par un système comprenant une cale pentée montée mobile sensiblement dans un plan tangent au cylindre et inclinée par rapport à l'axe longitudinal de celui-ci, sur laquelle est disposé le pion de centrage mobile.The control means can also be constituted by a system comprising a sloped wedge mounted substantially in a plane tangent to the cylinder and inclined relative to the longitudinal axis of this one, on which is disposed the centering pin mobile.

    • La figure 1 représente, sous forme déroulée, la surface externe d'un cylindre de découpe 1 d'axe longitudinal xx' et d'une plaque de découpe 3 qui est maintenue à la surface de celui-ci par des aimants longitudinaux, non représentés sur le dessin, qui sont répartis sur la périphérie du cylindre.FIG. 1 represents, in unwound form, the outer surface of a cutting cylinder 1 axis longitudinal axis xx 'and a cutting plate 3 which is held on the surface of it by magnets longitudinal, not shown in the drawing, which are distributed on the periphery of the cylinder.

    On désignera ci-après dans le présent texte par axe longitudinal xx' l'axe de rotation du cylindre 1, et par axe transversal zz' l'axe perpendiculaire à l'axe longitudinal xx' lorsque la surface de ce cylindre est déployée. Par ailleurs on désignera par grand axe uu' de la plaque 3 l'axe de celle-ci pouvant être disposé suivant l'axe transversal zz' du cylindre, et par petit axe vv' l'axe de la plaque 3 perpendiculaire au grand axe uu'.Hereinafter will be referred to in this text by axis longitudinal axis xx 'the axis of rotation of the cylinder 1, and by transverse axis zz 'the axis perpendicular to the axis longitudinal axis xx 'when the surface of this cylinder is deployed. Moreover, we will designate by major axis uu 'of the plate 3 the axis of which can be arranged along the transverse axis zz 'of the cylinder, and by small axis vv 'the axis of the plate 3 perpendicular to the major axis uu.

    On constate ainsi sur la figure 1 qu'un mauvais positionnement de la plaque 3 sur le cylindre 1 conduit à un décalage angulaire entre le grand axe uu' de la plaque 3 et l'axe transversal zz' de la surface supérieure déployée du cylindre 1.We thus see in Figure 1 that a bad positioning of the plate 3 on the cylinder 1 leads to an angular offset between the major axis uu 'of the plate 3 and the transverse axis zz 'of the upper surface deployed from the cylinder 1.

    La présente invention se propose ainsi d'éviter le décalage angulaire et de faire en sorte que le grand axe uu' de la plaque 3 soit parallèle à l'axe transversal zz' du cylindre 1.The present invention thus proposes to avoid the angular shift and to make sure that the major axis uu 'of the plate 3 is parallel to the transverse axis zz' of the cylinder 1.

    Pour ce faire, ainsi que représenté sur la figure 2, on a disposé sur la surface externe du cylindre 1, à proximité de l'un des bords de celui-ci, un pion de centrage fixe 5. On a réalisé, à la partie supérieure de la plaque 3, dans un angle de celle-ci correspondant au pion 5, un orifice 7 parfaitement ajusté au pion 5, et l'on comprend dès lors que si l'on fait effectuer à la plaque 3 une rotation suivant la flèche F autour du pion 5, il sera dès lors possible d'amener les axes uu' et zz' parallèles, ainsi que représenté sur la figure 2.To do this, as shown in FIG. disposed on the outer surface of the cylinder 1, to near one of the edges of it, a pawn of fixed centering 5. It was realized, at the top of the plate 3, at an angle thereof corresponding to the pion 5, an orifice 7 perfectly fitted to the pin 5, and it is understandable then that if one makes perform at the plate 3 a rotation following the arrow F around the pawn 5, it will be possible to bring the axes uu 'and zz' parallel, as shown in Figure 2.

    Pour effectuer une telle rotation on dispose sur le cylindre 1 un second pion de centrage 9 et l'on prévoit, dans la plaque 3, un orifice correspondant 11 parfaitement ajusté aux dimensions de celui-ci, de façon que, lorsque les pions 5 et 9 sont disposés dans les orifices 7 et 11, la plaque 3 soit parfaitement bloquée en position par rapport au cylindre 1. Le second pion 9 est disposé sur des moyens 13 permettant de le déplacer suivant la direction de l'axe transversal zz' du cylindre 1.To make such a rotation one has on the cylinder 1 a second centering pin 9 and is provided, in the plate 3, a corresponding orifice 11 perfectly adjusted to the dimensions of it, so that when the pieces 5 and 9 are arranged in the holes 7 and 11, the plate 3 is perfectly blocked in position relative to the cylinder 1. The second pawn 9 is disposed on means 13 for moving it in the direction of the transverse axis zz 'of the cylinder 1.

    Dans ces conditions, pour mettre en oeuvre l'invention on procédera ainsi que décrit ci-après.In these conditions, to implement the invention will proceed as described below.

    Dans un premier temps on positionnera le pion mobile 9 de façon qu'il soit à priori disposé sur un axe longitudinal du cylindre 1, c'est-à-dire un axe parallèle à son axe central et longitudinal xx', passant par le centre du pion 5, et l'on disposera la plaque 3 sur le cylindre 1, de façon qu'elle soit tenue par les deux pions 5 et 9. Ainsi que représenté sur la figure 3, la partie supérieure de la plaque 3 comportera un repère C et sa partie inférieure comportera un second repère D, les repères C et D se trouvant sur une ligne rigoureusement parallèle au grand axe uu' de la plaque 3. Une fois la plaque 3 déployée et tenue par toute sa surface sur le cylindre 1 par les moyens d'aimantation, on pourra alors mesurer le décalage a, existant suivant la direction de l'axe longitudinal xx' du cylindre, entre les points C et D. On démontera alors la plaque 3 du cylindre 1 et l'on déplacera le pion 9 suivant l'axe transversal zz' du cylindre 1 d'une valeur appropriée b, aisément déterminable par le calcul, et permettant de ramener à une valeur nulle le décalage a. Il suffira ensuite de repositionner la plaque 3 sur le cylindre 1 de façon qu'elle soit parfaitement centrée par les pions 5 et 9 pour que, une fois déployée sur le cylindre 1, elle se trouve en position correcte sur celui-ci, c'est-à-dire pour que la distance a soit nulle et donc que son axe uu' soit parallèle à l'axe transversal zz' du cylindre 1.In a first step, the mobile pin 9 will be positioned so that it is a priori disposed on a longitudinal axis of the cylinder 1, that is to say an axis parallel to its central and longitudinal axis xx ', passing through the center 5, and the plate 3 will be disposed on the cylinder 1, so that it is held by the two pins 5 and 9. As shown in FIG. 3, the upper part of the plate 3 will comprise a marker C and its lower part will have a second mark D, the marks C and D being on a line strictly parallel to the major axis uu 'of the plate 3. Once the plate 3 deployed and held by its entire surface on the cylinder 1 by the magnetization means, we can then measure the offset a , existing in the direction of the longitudinal axis xx 'of the cylinder, between the points C and D. Then disassemble the plate 3 of the cylinder 1 and move the pin 9 along the transverse axis zz 'of the cylinder 1 of an appropriate value b , easily determinable by calculation, and making it possible to reduce the offset a to zero. It will then suffice to reposition the plate 3 on the cylinder 1 so that it is perfectly centered by the pins 5 and 9 so that, once deployed on the cylinder 1, it is in the correct position thereon, c ' that is to say that the distance a is zero and therefore that its axis uu 'is parallel to the transverse axis zz' of the cylinder 1.

    Contrairement aux dispositifs complexes de l'état antérieur de la technique le maintien de la plaque 3 sur le cylindre 1 est assuré, sans qu'il soit nécessaire d'exercer une force de traction quelconque sur la plaque.Unlike the complex devices of the state prior art the maintenance of the plate 3 on the cylinder 1 is insured, without it being necessary to exert any tensile force on the plate.

    On a représenté sur la figure 4 un dispositif permettant de réaliser, de façon contrôlée, le déplacement requis du pion 9 suivant la direction de l'axe transversal zz' du cylindre 1. Ce dispositif est constitué d'un levier 15, qui est disposé dans une cavité 17 creusée dans le cylindre 1, et qui est monté à rotation autour d'un axe 19. L'extrémité interne du levier 15 s'articule autour du second pion de centrage 9 destiné à coopérer avec un pion de centrage 5 fixe solidaire du cylindre 1, pour assurer le positionnement de la plaque 3. L'extrémité externe opposée du levier 15 est percée d'un trou fileté dans lequel prend place une vis 21 dont l'extrémité vient en appui contre l'un des côtés bordant la cavité 17 sous l'action d'un ressort 25 qui prend appui, par chacune de ses extrémités, dans des cavités respectives 20 et 29 prévues dans le cylindre 1 et dans le levier 15. L'autre extrémité de la vis 21 est pourvue d'une tête de commande 23. On comprend que, par la rotation de la vis 21, on assure la rotation du levier 15 autour de l'axe 19 et, en conséquence, le déplacement du pion de centrage 9 suivant la direction transversale zz' du cylindre 1. On fera en sorte que la distance existant entre le centre du pion de centrage 9 et le centre de l'axe de rotation 19 soit importante en regard du déplacement souhaité du pion de centrage 9 suivant l'axe zz' du cylindre 1.FIG. 4 shows a device to achieve, in a controlled manner, the required movement of the pawn 9 following the direction of the transverse axis zz 'of the cylinder 1. This device is consisting of a lever 15, which is arranged in a cavity 17 dug into the cylinder 1, and who climbed into rotation about an axis 19. The inner end of lever 15 is articulated around the second centering pin 9 intended to cooperate with a fixed centering pin 5 integral with the cylinder 1, to ensure the positioning of the plate 3. The opposite external end of the lever 15 is pierced with a threaded hole in which takes place a screw 21 whose end bears against one of the sides bordering the cavity 17 under the action of a spring 25 which is supported, at each end, in respective cavities 20 and 29 provided in the cylinder 1 and in the lever 15. The other end of the screw 21 is provided with a control head 23. It is understood that the rotation of the screw 21, it ensures the rotation of the lever 15 around the axis 19 and, therefore, the displacement of the centering pin 9 in the transverse direction zz 'cylinder 1. We will make sure that the distance existing between the center of the centering pin 9 and the center of the axis of rotation 19 is important to of the desired displacement of the centering pin 9 next the axis zz 'of the cylinder 1.

    De façon à obtenir une bonne précision de réglage on peut pourvoir une portion de la tête 23 de la vis 21 d'un vernier 24.In order to obtain a good precision of adjustment one can provide a portion of the head 23 of the screw 21 of a vernier 24.

    De façon intéressante ce vernier 24 peut comporter des graduations qui correspondent à la valeur b du déplacement suivant la direction de l'axe zz' que l'on souhaite appliquer au pion 9. On peut également, ce qui simplifie le rôle du régleur, graduer le vernier 24 avec une graduation correspondant directement à la valeur a constituant le décalage dans le sens longitudinal xx' du cylindre 1, des deux repères C et D. Ainsi l'utilisateur, pour réaliser sa correction, n'aura qu'à effectuer la mesure de la valeur a et à reporter celle-ci sur le vernier 24 du bouton de commande de la vis 21.Interestingly, this vernier 24 may comprise graduations which correspond to the value b of the displacement in the direction of the axis zz 'that it is desired to apply to the pin 9. It may also, which simplifies the role of the adjuster, graduate the vernier 24 with a graduation corresponding directly to the value a constituting the offset in the longitudinal direction xx 'of the cylinder 1, of the two marks C and D. Thus, the user, in order to carry out his correction, will only have to perform the measuring the value a and postpone it on the vernier 24 of the screw control knob 21.

    La présente invention est particulièrement intéressante en ce qu'elle permet d'allier la simplicité du mode de fixation au caractère répétitif du réglage, si bien qu'il est possible de noter sur chacune des plaques 3 la valeur du décalage à régler sur le vernier 24 pour, sans opération préalable, assurer un positionnement correct de celle-ci. Il est ainsi possible à l'utilisateur de passer de façon particulièrement rapide d'une plaque 3 à une autre en fonction de ses besoins.The present invention is particularly interesting in that it allows to combine simplicity from the fixation mode to the repetitive nature of the setting, although it is possible to note on each of the plates 3 the value of the offset to be set on the vernier 24 for, without prior operation, ensure positioning correct of it. It is thus possible to the user to move particularly fast from one plate 3 to another according to its needs.

    Afin de faciliter la mise en place de la plaque 3, il est possible de donner à l'orifice destiné à recevoir le pion mobile 9 une forme allongée dans le sens longitudinal de l'axe du cylindre xx'. Dans ce mode de mise en oeuvre la largeur de la lumière 11', ainsi que représenté sur la figure 4a, sera égale au diamètre du pion de centrage 9.In order to facilitate the placement of the plate 3, it is possible to give to the orifice intended to receive the mobile pin 9 has an elongated shape in the direction longitudinal axis of the cylinder axis xx '. In this mode implementing the width of the light 11 ', as well as represented in FIG. 4a, will be equal to the diameter of centering pin 9.

    Ainsi que représenté sur la figure 4b, on pourrait bien entendu, dans le mode de mise en oeuvre de la figure 4, assurer une immobilisation du réglage effectué en réalisant, à l'extrémité du levier 15 portant la vis de réglage 21 une fente 22 conférant à cette extrémité une souplesse, et en rapprochant les deux lèvres 22' ainsi constituées, au moyen d'une vis de bridage 30 vissée dans le cylindre 1.As shown in Figure 4b, one could of course, in the embodiment of the figure 4, ensure immobilization of the adjustment made in realizing, at the end of the lever 15 carrying the screw of setting 21 a slot 22 conferring at this end a flexibility, and bringing the two lips 22 'together constituted by means of a clamping screw 30 screwed into the cylinder 1.

    On pourrait suivant l'invention, faire appel à tout autre moyen permettant d'assurer un déplacement contrôlé du pion de centrage 9 dans la direction transversale zz' du cylindre 1.We could according to the invention, call upon all other means to ensure controlled movement of the centering pin 9 in the transverse direction zz ' of the cylinder 1.

    On pourrait ainsi, comme représenté sur les figures 5 et 6, disposer le pion mobile de centrage 9' de façon excentrée sur un axe 26 de plus grand diamètre E, ce dernier étant monté à rotation dans un logement 27 prévu dans le cylindre 1. Bien entendu le diamètre E de l'axe 26 sera important par rapport au diamètre d du pion de centrage 9', de façon que le déplacement du centre O du pion 9' dans le sens longitudinal soit négligeable par rapport au déplacement requis de ce même centre O suivant l'axe transversal zz' du cylindre 1. Une fois mis dans la position requise le pion de centrage 9' sera immobilisé, par un blocage en rotation de l'axe 26 par tout moyen approprié.It would thus be possible, as shown in FIGS. 5 and 6, to arrange the mobile centering pin 9 'eccentrically on an axis 26 of larger diameter E, the latter being rotatably mounted in a housing 27 provided in the cylinder 1. Of course, the diameter E of the axis 26 will be large relative to the diameter d of the centering pin 9 ', so that the displacement of the center O of the pin 9' in the longitudinal direction is negligible compared to the required displacement of the same center O along the transverse axis zz 'of the cylinder 1. Once put in the required position, the centering pin 9' will be immobilized, by locking in rotation of the axis 26 by any appropriate means.

    On pourrait également bien entendu suivant l'invention inverser de façon cinématique les pions de centrage prévus sur le cylindre 1 et les orifices prévus dans la plaque. Ainsi, comme représenté sur les figures schématiques 7 et 8, la plaque 3 est pourvue d'un tenon 9" qui vient prendre place dans un orifice 12 prévu sur la surface supérieure de l'axe 26. De même le pion fixe 5 sera disposé sur la plaque 3 et l'orifice correspondant sera creusé dans le cylindre 1.One could also of course following the invention kinematically invert the pions of centered on the cylinder 1 and the holes provided in the plate. Thus, as shown in the figures schematic 7 and 8, the plate 3 is provided with a tenon 9 "which comes to take place in a hole 12 provided on the upper surface of the axis 26. Similarly the fixed pin 5 will be placed on the plate 3 and the corresponding orifice will be dug in the cylinder 1.

    On pourrait également suivant l'invention, afin de déplacer le téton mobile 9 suivant l'axe transversal zz' du cylindre 1, remplacer le levier par un système de coulisseau, ainsi que représenté sur la figure 9. Sur cette figure la surface externe du cylindre 1 est creusée d'une rainure 40 dont l'axe aa' est incliné d'un angle α par rapport à la direction transversale zz' du cylindre 1. Cette rainure 40 reçoit un coulisseau 42 qui est mobile en translation à l'intérieur de celle-ci sous l'action d'une vis 44 qui est vissée dans le coulisseau 42 et qui est immobilisée en translation par rapport au cylindre 1 et mobile en rotation par rapport à celui-ci. On comprend dans ces conditions que tout mouvement de rotation communiqué à la vis 44 par un organe de commande 46 disposé en extrémité de celle-ci a pour effet de déplacer le pion 9 suivant l'axe aa', par exemple d'une longueur l, et qu'à ce déplacement correspond un déplacement suivant l'axe transversal zz' égal à lcosα. Dans un tel mode de mise en oeuvre on utilisera un orifice de réception du pion 9 de forme allongée ainsi que représenté sur la figure 4a.One could also according to the invention, in order to move the movable pin 9 along the transverse axis zz 'of the cylinder 1, replace the lever by a slider system, as shown in Figure 9. In this figure the outer surface of the cylinder 1 is hollowed out with a groove 40 whose axis aa 'is inclined at an angle α with respect to the transverse direction zz' of the cylinder 1. This groove 40 receives a slide 42 which is movable in translation inside. of the latter under the action of a screw 44 which is screwed into the slide 42 and which is immobilized in translation relative to the cylinder 1 and rotatable relative thereto. It is understood in these conditions that any rotational movement communicated to the screw 44 by a control member 46 disposed at the end thereof has the effect of moving the pin 9 along the axis aa ', for example a length l , and that displacement corresponds to a displacement along the transverse axis zz 'equal to lcosα. In such an embodiment, use will be made of an orifice for receiving the elongate pin 9 as shown in FIG. 4a.

    Dans un mode de mise en oeuvre particulièrement intéressant de l'invention, des moyens d'aide à la mise en place et au retrait de la plaque 3 sont prévus. Ainsi que représenté sur les figures 10 et 11, ces moyens sont essentiellement constitués d'une plaque plane de positionnement 50 constituée d'un matériau non magnétique, qui est en mesure d'être disposée à l'aide de moyens (non représentés sur le dessin) de façon que sa face inférieure soit sensiblement tangentielle à la surface externe du cylindre 1. Préférentiellement, ainsi que représenté sur la figure 10, les angles supérieurs de la plaque de positionnement 50 sont pourvus d'échancrures 52 destinées à dégager les pions 5, 9 qui assurent le maintien de la plaque 3. Une telle disposition permet à l'utilisateur de positionner facilement l'orifice 7 de la plaque 3 sur le pion fixe 5 solidaire du cylindre 1 puisque, dans ces conditions, l'effet d'aimantation provoqué par les éléments magnétiques noyés dans le cylindre 1 ne s'exerce sur la plaque que par la surface réduite de celle-ci se trouvant dégagée par l'échancrure 52. Grâce à la plaque de positionnement 50 l'utilisateur pourra ainsi faire pivoter facilement la plaque 3 pour mettre en place le second orifice libre dans le pion mobile 9.In an embodiment particularly interesting of the invention, means of assisting the in place and the removal of the plate 3 are provided. So as shown in Figures 10 and 11, these means are essentially consisting of a flat plate of positioning 50 made of non-material magnetic, which is able to be arranged with the help of means (not shown in the drawing) so that its bottom face is substantially tangential to the outer surface of the cylinder 1. Preferably, thus as shown in Figure 10, the upper angles of the positioning plate 50 are provided with notches 52 to release the pins 5, 9 which ensure the maintaining the plate 3. Such a provision allows the user to easily position the orifice 7 of the plate 3 on the fixed pin 5 secured to the cylinder 1 since, under these conditions, the magnetization effect caused by the magnetic elements embedded in the cylinder 1 is exerted on the plate only by the surface reduced of it being released by the notch 52. With the positioning plate 50 the user can easily rotate the plate 3 to set up the second free hole in the pawn mobile 9.

    Ainsi que représenté sur la figure 11 la plaque de positionnement 50 pourra être constituée de deux éléments, à savoir un élément support épais 50a rigide et un élément 50b plus mince et de plus faible épaisseur que le pion 5.As shown in FIG. positioning 50 may consist of two elements, namely a rigid support member 50a rigid and a 50b element thinner and thinner than the pawn 5.

    On utilisera bien entendu une telle plaque pour la mise en place de chacun des cylindres associés par exemple un cylindre de découpe et son cylindre contrepartie. We will of course use such a plate for setting up each of the associated cylinders by example a cutting cylinder and its cylinder counterparty.

    Une telle plaque facilite également le retrait de la plaque 3.Such a plate also facilitates the removal of the plate 3.

    Pour faciliter la prise, nécessaire au retrait de la plaque 3 du cylindre 1, l'un des angles inférieurs de celle-ci sera préférentiellement taillé de façon à présenter un biseau 54. Pour la saisir l'utilisateur pourra ainsi glisser une spatule métallique 56 dans l'angle formé par le biseau 54 et la surface supérieure du cylindre 1 de façon à pouvoir décoller la plaque 3 de la surface de ce dernier.To facilitate the taking, necessary to the withdrawal of the plate 3 of cylinder 1, one of the lower angles of this one will be preferentially cut so as to present a bevel 54. To grab the user can slide a metal spatula 56 into the angle formed by the bevel 54 and the upper surface of the cylinder 1 so as to be able to take off the plate 3 of the surface of the latter.

    Ainsi que mentionné précédemment la présente invention permet également d'assurer la correction de positionnement angulaire relatif de deux plaques disposées sur deux cylindres associés tels qu'un cylindre de découpe et son cylindre contrepartie. Pour ce faire l'un des deux cylindres au moins utilisera deux pions mobiles 9 réglables suivant l'axe transversal zz' du cylindre. Cette disposition permet en effet si on le souhaite de déplacer les deux pions parallèlement à cet axe transversal zz', c'est-à-dire de faire tourner la plaque par rapport au cylindre tout en la maintenant parallèlement à elle-même.As mentioned earlier this invention also makes it possible to ensure the correction of relative angular positioning of two plates disposed on two associated cylinders such as a cylinder cutting and its counterpart cylinder. To do this at least one of the two cylinders will use two pieces movable 9 adjustable along the transverse axis zz 'of the cylinder. This provision indeed makes it possible wish to move the two pawns parallel to this transverse axis zz ', that is to say to rotate the plate relative to the cylinder while maintaining it parallel to itself.

    La présente invention permet également avec le même dispositif de corriger à la fois le positionnement angulaire relatif de deux cylindres associés et d'effectuer la correction d'orientation de la plaque en conférant à chacun des deux tétons mobiles 9 déplacés dans le sens transversal zz' du cylindre des déplacements différents.The present invention also allows with the same device to correct both the positioning relative angularity of two associated cylinders and to perform the orientation correction of the plate in conferring on each of the two movable nipples 9 displaced in the transverse direction zz 'of the displacement cylinder different.
