Description

L'invention a trait à une machine à couper et à plier une bande de papier imprimé, utilisée notamment en aval d'une imprimante rotative.The invention relates to a machine for cutting and folding a strip of printed paper, used in particular downstream of a rotary printer.

On connaît déjà une telle machine, qu'illustrent les figures 1 à 3, avec des cahiers qu'elle produit :

  • la figure 1 est une élévation schématique partielle de la machine ;
  • la figure 2 montre en perspective un cahier tabloïd, c'est-à-dire un cahier obtenu directement à la sortie du cylindre plieur ; et
  • la figure 3 montre en perspective un cahier obtenu à la sortie du cylindre de deuxième pli.
We already know such a machine, illustrated in Figures 1 to 3, with notebooks it produces:
  • Figure 1 is a partial schematic elevation of the machine;
  • Figure 2 shows in perspective a tabloid notebook, that is to say a notebook obtained directly at the outlet of the folding cylinder; and
  • Figure 3 shows in perspective a notebook obtained at the exit of the second fold cylinder.

La machine comporte un triangle 1, un cylindre coupeur 2, un cylindre de transfert 3, un cylindre plieur 4, et un cylindre de deuxième pli 5.The machine comprises a triangle 1, a cutting cylinder 2, a transfer cylinder 3, a folding cylinder 4, and a second fold cylinder 5.

La bande imprimée passe d'abord dans le triangle 1 qui réalise à mi-distance de ses bords un pli longitudinal 6 (voir figures 2 et 3), généralement dit pli triangle, puis la bande pliée 7 passe entre le cylindre coupeur 2 et le cylindre de transfert 3 où se réalise une coupe transversale séparant un exemplaire 8 de la bande pliée 7, l'exemplaire 8 passe ensuite entre les cylindres de transfert 3 et plieur 4 où se réalise un pli transversal 9, généralement dit premier pli, à mi-distance des coupes 10 qui limitent l'exemplaire 8, qui devient à la fin de ce pliage un cahier tabloïd 11 tel que celui montré sur la figure 2, qui soit est décollé directement du cylindre plieur 4, soit - comme c'est le cas dans la configuration illustrée - passe entre le cylindre plieur 4 et le cylindre de deuxième pli 5 où se réalise un pli transversal 12, généralement dit deuxième pli, à mi-distance des coupes transversales 10 (qui sont alors adjacentes) et du premier pli 9, ce qui permet d'obtenir un cahier 13 tel que celui illustré sur la figure 3.The printed strip passes first through the triangle 1 which achieves a longitudinal fold 6 mid-distance from its edges (see FIGS. 2 and 3), generally called a triangle fold, then the folded strip 7 passes between the cutting cylinder 2 and the transfer cylinder 3 where a cross section is made separating a copy 8 from the folded strip 7, the copy 8 then passes between the transfer cylinders 3 and folder 4 where a transverse fold 9, generally called the first fold, is made at mid -distance from the cuts 10 which limit the copy 8, which becomes at the end of this folding a tabloid notebook 11 such as that shown in FIG. 2, which is either peeled off directly from the folding cylinder 4, or - as is the case in the illustrated configuration - pass between the folding cylinder 4 and the second fold cylinder 5 where a transverse fold 12 is produced, generally called the second fold, midway between the transverse cuts 10 (which are then adjacent) and the first fold 9, what i makes it possible to obtain a notebook 13 such as that illustrated in FIG. 3.

Le cylindre coupeur 2 a une circonférence égale à la longueur d'impression sur le papier (il a le même diamètre que le (ou les) cylindres d'impression de l'imprimante) et est muni le long d'une génératrice (c'est-à-dire d'une ligne de sa surface latérale parallèle à son axe de rotation) d'une scie 14 qui coopère successivement avec l'une des rainures 15A ou 15B du cylindre de transfert 3 pour couper la bande pliée 7.The cutting cylinder 2 has a circumference equal to the length of printing on the paper (it has the same diameter as the printing cylinder (s) of the printer) and is provided along a generator (it that is to say from a line of its lateral surface parallel to its axis of rotation) of a saw 14 which cooperates successively with one of the grooves 15A or 15B of the transfer cylinder 3 to cut the folded strip 7.

Le cylindre de transfert 3 a un diamètre double de celui du cylindre 2 de telle sorte qu'un exemplaire 8 le recouvre sur un demi-pourtour. A proximité et en aval de chaque rainure 15A ou 15B, il comporte une rangée d'aiguilles 16A ou 16B, généralement dites pointures, qui sortent ou se rétractent par rapport à la surface du cylindre 3 pour respectivement maintenir sur le cylindre la bande 7 ou l'exemplaire 8 - en les traversant (ce qui laisse des traces 17, visibles sur les figures 2 et 3) - ou bien les relâcher, lorsque nécessaire.The transfer cylinder 3 has a diameter twice that of the cylinder 2 so that a copy 8 covers it over a half-circumference. Near and downstream of each groove 15A or 15B, it comprises a row of needles 16A or 16B, generally called sizes, which come out or retract with respect to the surface of the cylinder 3 to respectively maintain the strip 7 or copy 8 - by crossing them (which leaves traces 17, visible in Figures 2 and 3) - or release them, when necessary.

A mi-distance entre les pointures 16A et 16B, le cylindre de transfert 3 comporte une lame engageante 18A ou 18B qui engage la portion de l'exemplaire 8 qui la recouvre dans la mâchoire 19A ou 19B du cylindre plieur 4, ce qui forme le premier pli 9.Halfway between the sizes 16A and 16B, the transfer cylinder 3 comprises an engaging blade 18A or 18B which engages the portion of the specimen 8 which covers it in the jaw 19A or 19B of the folding cylinder 4, which forms the first fold 9.

Dans la configuration illustrée, le cylindre plieur 4 comporte également deux lames engageantes 20A et 20B similaires à celles du cylindre 3 qui engagent respectivement la portion du cahier tabloïd 11 qui les recouvre dans la mâchoire 21A ou 21B du cylindre de deuxième pli 5 pour former le deuxième pli 12 et le cahier 13 ainsi formé est extrait du cylindre 5 par le décolleur 22 qui le dirige sur le tapis 23 qui le fait poursuivre sa progression dans la machine.In the illustrated configuration, the folding cylinder 4 also comprises two engaging blades 20A and 20B similar to those of the cylinder 3 which respectively engage the portion of the tabloid notebook 11 which covers them in the jaw 21A or 21B of the second fold cylinder 5 to form the second fold 12 and the notebook 13 thus formed is extracted from the cylinder 5 by the stripper 22 which directs it onto the belt 23 which causes it to continue its progression in the machine.

Lorsqu'on désire passer de la configuration représentée à celle où l'on décolle directement le cahier tabloïd du cylindre 4, par le décolleur 24 qui le dirige sur le tapis 25, il faut réaliser un certain nombre d'opérations, et notamment débrayer le cylindre 5, changer la position du décolleur 24 pour le faire passer de la position hors service représentée à sa position de travail, agir sur le mécanisme de commande des mâchoires 19A et 19B pour les faire s'ouvrir à proximité du décolleur 24 et non du point où elles se trouvent lorsque les lames 20A et 20B se trouvent dans les mâchoires 21A et 21B, démonter les lames engageantes 20A et 20B, et monter dans les rainures 24A et 24B qui les logeaient une barre de remplissage.When you want to switch from the configuration shown to that where you directly take off the tabloid notebook from cylinder 4, by the stripper 24 which directs it on the mat 25, you have to perform a certain number of operations, and in particular disengage the cylinder 5, change the position of the stripper 24 to move it from the out-of-service position shown to its working position, act on the jaw control mechanism 19A and 19B to make them open near the stripper 24 and not at the point where they are when the blades 20A and 20B are in the jaws 21A and 21B, dismantle the engaging blades 20A and 20B, and mount in the grooves 24A and 24B which housed them a bar of filling.

L'invention vise à simplifier les opérations de passage d'une configuration à l'autre sur une machine de ce genre.The invention aims to simplify the operations of switching from one configuration to another on a machine of this kind.

Elle propose à cet effet que la machine soit munie d'un cylindre plieur qui comporte au moins une lame engageante mobile entre deux positions fixes dans chacune desquelles reste la lame engageante lorsque tourne en service le cylindre plieur, une position sortie où elle fait saillie par rapport à la surface latérale du cylindre et est adaptée à coopérer avec une mâchoire du cylindre de deuxième pli, et une position rétractée où elle se trouve à l'intérieur du cylindre plieur, cette lame engageante étant destinée à être mise en position sortie lorsqu'on veut réaliser ledit deuxième pli tandis que sinon elle est mise en position rétractée.To this end, it proposes that the machine be provided with a folding cylinder which comprises at least one engaging blade movable between two fixed positions in each of which remains the engaging blade when the folding cylinder remains in service, an extended position where it projects by relative to the lateral surface of the cylinder and is adapted to cooperate with a jaw of the cylinder of the second fold, and a retracted position where it is located inside the folding cylinder, this engaging blade being intended to be put in the extended position when we want to make said second fold while otherwise it is put in the retracted position.

L'invention permet donc d'éviter à la fois l'opération de montage ou de démontage des lames engageantes et l'opération de montage ou de démontage des barres de remplissage.The invention therefore makes it possible to avoid both the assembly or disassembly operation of the engaging blades and the assembly or disassembly operation of the filling bars.

Elle simplifie donc considérablement la tâche de l'opérateur chargé du passage d'une configuration à l'autre, et réduit notablement le temps nécessaire à cette manoeuvre.It therefore considerably simplifies the task of the operator responsible for switching from one configuration to another, and significantly reduces the time required for this maneuver.

Selon une caractéristique préférée de l'invention, le cylindre plieur comporte deux butées limitant la course de la lame engageante correspondant respectivement à la position sortie et à la position rétractée.According to a preferred characteristic of the invention, the folding cylinder has two stops limiting the travel of the engaging blade corresponding respectively to the extended position and to the retracted position.

Il suffit donc à l'opérateur de passer d'une butée à l'autre, sans avoir à vérifier s'il a fait correctement rentrer ou sortir la lame.The operator therefore only has to pass from one stop to the other, without having to check whether he has correctly retract or remove the blade.

Selon une autre caractéristique préférée de l'invention, la lame est liée à un mécanisme comportant un élément élastique et admettant entre lesdites butées une configuration où est comprimé au maximum ledit élément élastique et de part et d'autre de laquelle l'élément élastique sollicite le mécanisme d'une façon stable vers l'une desdites butées.According to another preferred characteristic of the invention, the blade is linked to a mechanism comprising an elastic element and admitting between said stops a configuration in which said elastic element is compressed as much as possible and on either side of which the elastic element biases the mechanism stably towards one of said stops.

Il suffit donc de franchir le point de compression maximale pour que la lame aille automatiquement se placer dans la position opposée à celle dont on est parti. Si l'élément élastique est suffisamment puissant, il peut assurer le maintien en position de la lame, sinon on peut compléter l'immobilisation de la lame par serrage.It is therefore sufficient to cross the point of maximum compression for the blade to automatically go to place in the opposite position to that from which we started. If the elastic element is sufficiently powerful, it can maintain the blade in position, otherwise the immobilization of the blade can be completed by tightening.

Dans les versions de l'invention sans mécanisme à élément élastique, on utilisera de préférence le maintien par serrage, qui est particulièrement sûr.In versions of the invention without mechanism with elastic element, use will preferably be made of clamping, which is particularly safe.

Dans le cas le plus courant où le cylindre plieur comporte plusieurs lames engageantes, et notamment deux lames diamétralement opposées comme dans l'exemple qui précède, il est particulièrement avantageux de prévoir un dispositif d'accouplement entre les lames pour les faire passer simultanément de la position sortie à la position rétractée et vice-versa.In the most common case where the folding cylinder comprises several engaging blades, and in particular two diametrically opposite blades as in the preceding example, it is particularly advantageous to provide a coupling device between the blades to pass them simultaneously from the extended position to retracted position and vice versa.

On augmente encore ainsi le gain de temps procuré par l'invention, puisqu'on fait changer toutes les lames de position en une seule manoeuvre.This further increases the time saving provided by the invention, since all the position blades are changed in a single operation.

Les caractéristiques, particularités et avantages de l'invention apparaîtront au cours de la description donnée ci-après à titre d'exemple illustratif et non limitatif, en référence aux figures 4 à 10 des dessins annexés :

  • la figure 4 est une vue schématique en élévation latérale d'un cylindre plieur conforme à l'invention, les lames engageantes étant en position rétractée ;
  • la figure 5 est une vue similaire à la figure 4, les lames engageantes étant en position sortie ;
  • la figure 6 est une vue partielle en demi-coupe, indiquée en VI-VI sur la figure 4 ;

  • la figure 8 est une vue partielle en coupe, indiquée en VIII-VIII sur la figure 7 ; et
  • les figures 9 et 10 illustrent un mécanisme permettant de faire basculer automatiquement les lames de la position rétractée à la position sortie et vice-versa.
The characteristics, features and advantages of the invention will become apparent during the description given below by way of illustrative and nonlimiting example, with reference to FIGS. 4 to 10 of the appended drawings:
  • Figure 4 is a schematic side elevational view of a folding cylinder according to the invention, the engaging blades being in the retracted position;

  • Figure 8 is a partial sectional view, indicated in VIII-VIII in Figure 7; and
  • Figures 9 and 10 illustrate a mechanism for automatically tilting the blades from the retracted position to the extended position and vice versa.

Le cylindre plieur 30 est destiné à remplacer le cylindre 4 montré sur la figure 1. Il comporte une portion centrale 31, illustrée monobloc pour simplifier les dessins, une plaque cylindrique 32 qui recouvre latéralement la portion centrale, et des flasques 33A et 33B faisant corps avec la partie centrale aux extrémités respectives du cylindre 30.The folding cylinder 30 is intended to replace the cylinder 4 shown in FIG. 1. It comprises a central portion 31, illustrated in one piece to simplify the drawings, a cylindrical plate 32 which laterally covers the central portion, and flanges 33A and 33B forming a body with the central part at the respective ends of the cylinder 30.

Il est muni de deux mâchoires de premier pli 34A et 34B diamétralement opposées, similaires aux mâchoires 19A et 19B du cylindre 4 de la figure 1, qui comportent chacune une mâchoire fixe 35A ou 35B et une lame mobile 36A ou 36B ; ainsi que de deux lames engageantes diamétralement opposées 37A et 37B à environ un huitième de tour en aval des mâchoires respectives 34A et 34B.It is provided with two jaws of first fold 34A and 34B diametrically opposite, similar to the jaws 19A and 19B of the cylinder 4 of FIG. 1, which each comprise a fixed jaw 35A or 35B and a movable blade 36A or 36B; as well as two diametrically opposite engaging blades 37A and 37B about an eighth of a turn downstream of the respective jaws 34A and 34B.

Conformément à l'invention, ces lames engageantes sont mobiles entre deux positions fixes, la position sortie représentée sur la figure 5 où elles font saillie par rapport à la surface latérale du cylindre - et plus précisément par rapport à la plaque 32 - et où elles sont respectivement adaptées à coopérer avec une mâchoire telle que la mâchoire 21A ou la mâchoire 21B du cylindre de deuxième pli 5 ; et la position rétractée montrée sur la figure 4 où elles se trouvent à l'intérieur du cylindre 30.According to the invention, these engaging blades are movable between two fixed positions, the extended position shown in FIG. 5 where they protrude relative to the lateral surface of the cylinder - and more precisely relative to the plate 32 - and where they are respectively adapted to cooperate with a jaw such as the jaw 21A or the jaw 21B of the second fold cylinder 5; and the retracted position shown in FIG. 4 where they are inside the cylinder 30.

Lorsque les lames 37A et 37B sont en position sortie (figure 5), le cylindre 30 s'utilise comme le cylindre 4 dans la configuration montrée sur la figure 1 ; et lorsque les lames sont rétractées (figure 4), il s'utilise comme le cylindre 4 lorsqu'on y a démonté les lames 20A et 20B et remplacé celles-ci par des barres de remplissage.When the blades 37A and 37B are in the extended position (FIG. 5), the cylinder 30 is used like the cylinder 4 in the configuration shown in FIG. 1; and when the blades are retracted (FIG. 4), it is used like the cylinder 4 when the blades 20A and 20B have been disassembled there and replaced these by filling bars.

Un dispositif d'accouplement est prévu entre les lames 37A et 37B pour les faire passer simultanément de la position sortie à la position rétractée et vice-versa; Il comporte, pour chaque lame engageante, un arbre 38A ou 38B articulé sur le cylindre suivant un axe 39A ou 39B parallèle à l'axe de rotation 40 du cylindre, arbre sur lequel est montée la lame qui est donc mobile entre les positions sortie et rétractée par rotation de l'arbre pour chaque arbre, un levier 41A ou 41B portant à une première extrémité un galet 42A ou 42B respectivement articulé autour d'un axe 50A ou 50B, et solidarisé à l'arbre à une deuxième extrémité ; un collier 43 articulé sur le cylindre suivant le même axe de rotation 40, et comportant pour chaque levier une chape 44A ou 44B orientée radialement dans laquelle est engagé à coulissement le galet du levier.A coupling device is provided between the blades 37A and 37B for passing them simultaneously from the extended position to the retracted position and vice versa; It comprises, for each engaging blade, a shaft 38A or 38B articulated on the cylinder along an axis 39A or 39B parallel to the axis of rotation 40 of the cylinder, shaft on which the blade is mounted which is therefore movable between the extended positions and retracted by rotation of the shaft for each shaft, a lever 41A or 41B carrying at a first end a roller 42A or 42B respectively articulated around an axis 50A or 50B, and secured to the shaft at a second end; a collar 43 articulated on the cylinder along the same axis of rotation 40, and comprising for each lever a yoke 44A or 44B oriented radially in which is engaged in sliding the roller of the lever.

Les leviers 41A et 41B sont solidarisés à leur arbre respectif par serrage, grâce à la vis 45A ou 45B, et les arbres 38A et 38B sont disposés respectivement dans une gorge 46A ou 46B du cylindre, adaptée à loger la lame dans la position rétractée, et ils sont articulés à chaque extrémité sur les flasques 33A et 33B (voir figures 6 à 8 pour l'arbre 38A).The levers 41A and 41B are secured to their respective shaft by tightening, by means of the screw 45A or 45B, and the shafts 38A and 38B are disposed respectively in a groove 46A or 46B of the cylinder, adapted to accommodate the blade in the retracted position, and they are articulated at each end on the flanges 33A and 33B (see FIGS. 6 to 8 for the shaft 38A).

Le collier 43 tourne librement autour de la fusée 47 du cylindre, tandis que latéralement il est maintenu entre le flasque 33A et deux pattes 48A et 48B vissées sur celui-ci.The collar 43 rotates freely around the rocket 47 of the cylinder, while laterally it is held between the flange 33A and two lugs 48A and 48B screwed onto it.

Le glissement du galet 42A ou 42B dans la chape 44A ou 44B rend possible la rotation simultanée du collier 43 et des arbres 38A et 38B, en absorbant la variation de distance qui se produit au cours de la rotation entre l'extrémité du levier 41A ou 41B et l'axe 40 autour duquel tourne le collier.The sliding of the roller 42A or 42B in the yoke 44A or 44B makes possible the simultaneous rotation of the collar 43 and shafts 38A and 38B, by absorbing the variation in distance which occurs during the rotation between the end of the lever 41A or 41B and the axis 40 around which the collar rotates.

Deux butées 49A et 49B qui correspondent respectivement à la position rétractée et à la position sortie sont prévues sur le cylindre pour faciliter la tâche de l'opérateur, qui doit simplement aller d'une butée à l'autre lorsqu'il doit faire passer les lames d'une position à l'autre.Two stops 49A and 49B which correspond respectively to the retracted position and to the extended position are provided on the cylinder to facilitate the task of the operator, who simply has to go from one stop to the other when he has to pass the blades from one position to another.

La butée 49B, qui correspond à la position sortie, est réglable, ce qui offre l'avantage de permettre d'effectuer si nécessaire un ajustement de la position lame sortie.The stop 49B, which corresponds to the extended position, is adjustable, which has the advantage of allowing adjustment of the extended blade position if necessary.

Entre les butées 49A et 49B, le dispositif d'accouplement admet une configuration où les axes d'articulation 39A, 50A et 40 ou 39B, 50B et 40, qui sont parallèles, sont coplanaires, c'est-à-dire une configuration où le galet 42A ou 42B est rapproché au maximum du collier 43.Between the stops 49A and 49B, the coupling device has a configuration where the articulation axes 39A, 50A and 40 or 39B, 50B and 40, which are parallel, are coplanar, that is to say a configuration where the roller 42A or 42B is brought as close as possible to the collar 43.

Un évidement cylindrique est prévu au fond de chaque chape, et un ressort 51A ou 51B y est disposé, qui tend à éloigner chaque galet du collier.A cylindrical recess is provided at the bottom of each yoke, and a spring 51A or 51B is disposed there, which tends to distance each roller from the collar.

Chaque ressort est comprimé au maximum dans la configuration où le galet est rapproché au maximum du collier, et de part et d'autre de cette configuration il sollicite de façon stable le collier, soit vers la butée 49A, soit vers la butée 49B.Each spring is compressed as much as possible in the configuration where the roller is brought as close as possible to the collar, and on either side of this configuration it biases the collar in a stable manner, either towards the stop 49A or towards the stop 49B.

Ainsi, pour passer de la position sortie à la position rétractée ou vice-versa, il faut d'abord comprimer les ressorts jusqu'au point de compression maximal (qui est commun aux deux ressorts), et une fois qu'on l'a franchi, les ressorts vont amener automatiquement le collier jusqu'à la butée opposée à celle dont il est parti.Thus, to move from the extended position to the retracted position or vice versa, it is first necessary to compress the springs to the point of maximum compression (which is common to both springs), and once it has been crossed, the springs will automatically bring the collar to the stop opposite to that from which it started.

On notera qu'il aurait suffi d'un seul ressort disposé au fond soit de la chape 44A, soit de la chape 44B, pour obtenir ce fonctionnement, mais qu'il est intéressant de prévoir un ressort au fond de chaque chape pour augmenter la force avec laquelle est appliqué le collier sur les butées 49A ou 49B.It will be noted that it would have been sufficient for a single spring disposed at the bottom of either the yoke 44A or the yoke 44B, to obtain this operation, but it is advantageous to provide a spring at the bottom of each yoke to increase the force with which the collar is applied to the stops 49A or 49B.

Si les ressorts sont suffisamment puissants, il pourront assurer le maintien des lames en position sortie ou rétractée, sinon il faut prévoir des moyens complémentaires, comme c'est ici le cas : le palier formé dans le flasque 33B pour monter l'arbre 38A est fendu et comporte une vis 52 pour le serrer et immobiliser l'arbre en rotation (voir figures 7 et 8).If the springs are sufficiently powerful, they will be able to maintain the blades in the extended or retracted position, otherwise it is necessary to provide additional means, as is the case here: the bearing formed in the flange 33B for mounting the shaft 38A is split and has a screw 52 to tighten it and immobilize the rotating shaft (see Figures 7 and 8).

Pour commander le passage des lames d'une position fixe à l'autre, on peut agir sur le collier 43, sur l'un des leviers 41A ou 41B, ou bien comme c'est ici le cas, sur l'un des arbres 38A ou 38B qui sont plus accessibles.To control the passage of the blades from a fixed position to the other, one can act on the collar 43, on one of the levers 41A or 41B, or else as it is the case here, on one of the shafts 38A or 38B which are more accessible.

Dans le mode de réalisation montré sur les figures 7 et 8, le bout de l'arbre 38A opposé à celui montré sur les figures 4 et 5, comporte un bossage 53 prismatique et plus précisément hexagonal, destiné à être commandé par une clé.In the embodiment shown in Figures 7 and 8, the end of the shaft 38A opposite to that shown in Figures 4 and 5, has a prismatic boss 53 and more precisely hexagonal, intended to be controlled by a key.

Les dimensions du bossage 53 et de la tête de la vis 52 sont avantageusement identiques, on peut en effet utiliser ainsi la même clé pour desserrer le palier, faire tourner l'arbre 38A, et resserrer le palier.The dimensions of the boss 53 and of the head of the screw 52 are advantageously identical, it is indeed possible to use the same key to loosen the bearing, rotate the shaft 38A, and tighten the bearing.

Dans une variante montrée sur les figures 9 et 10, il n'y a pas d'immobilisation par serrage (les ressorts sont suffisamment puissants), le moyen de prise sur l'arbre n'est plus un bossage prismatique, mais une came 54 à deux rampes inclinées opposées 55A et 55B solidarisée au bout de l'arbre 38A, et l'élément de commande comporte : un levier 56 en forme de V articulé à sa pointe sur un arbre 57 solidaire du bâti de la machine tandis que chaque extrémité opposée à la pointe porte un galet 58A ou 58B ; deux butées 59A et 59B entre lesquelles est mobile le levier 56, correspondant respectivement à la position sortie (figure 10) et à la position rétractée (figure 9) des lames, l'un des galets agissant au cours d'une rotation lente du cylindre sur l'une des rampes de la came pour faire tourner l'arbre jusqu'à la position voulue, s'il n'y est pas, c'est-à-dire au moins jusqu'à passer le point de compression maximale ; et des moyens de commande du levier 56.In a variant shown in FIGS. 9 and 10, there is no immobilization by clamping (the springs are sufficiently powerful), the gripping means on the shaft is no longer a prismatic boss, but a cam 54 with two opposite inclined ramps 55A and 55B secured to the end of the shaft 38A, and the control element comprises: a lever 56 in the form of a V articulated at its tip on a shaft 57 secured to the frame of the machine while each end opposite the point carries a roller 58A or 58B; two stops 59A and 59B between which the lever 56 is movable, corresponding respectively to the extended position (Figure 10) and in the retracted position (Figure 9) of the blades, one of the rollers acting during a slow rotation of the cylinder on one of the ramps of the cam to rotate the shaft to the desired position, if not there, that is to say at least until passing the point of maximum compression; and lever control means 56.

Dans la position montrée sur la figure 9 (lame rétractée), la rampe 55A, qui était dans la position de la figure 10, est venue porter sur le galet 58A, ce qui a fait basculer la rampe à la position représentée, c'est-à-dire que le collier 43 a basculé de la butée 49B à la butée 49A.In the position shown in Figure 9 (blade retracted), the ramp 55A, which was in the position of Figure 10, came to bear on the roller 58A, which caused the ramp to tilt to the position shown, this is that is, the collar 43 has tilted from the stop 49B to the stop 49A.

A l'inverse, dans la position montrée sur la figure 10, c'est la rampe 55B qui est venue porter sur le galet 58B, faisant passer le collier 43 de la butée 49A à la butée 49B.Conversely, in the position shown in Figure 10, it is the ramp 55B which came to bear on the roller 58B, passing the collar 43 from the stop 49A to the stop 49B.

Dans la réalisation illustrée, les moyens de commande du levier en V comportent un vérin 60, tandis que dans une variante non illustrée, ils comportent une tige. On notera que les moyens de commande montrés sur les figures 9 et 10 offrent l'avantage de permettre une commande à distance et un passage automatique de l'une à l'autre des positions de la lame.In the illustrated embodiment, the control means of the V-shaped lever comprise a jack 60, while in a variant not illustrated, they comprise a rod. Note that the control means shown in Figures 9 and 10 offer the advantage of allowing remote control and automatic passage from one to the other of the blade positions.

Dans des variantes non représentées, qui sont susceptibles d'être intéressantes en fonction de la machine à laquelle est destiné le cylindre plieur, celui-ci ne comporte qu'une seule lame engageante, ou bien davantage que deux lames.In variants not shown, which are likely to be interesting depending on the machine for which the folding cylinder is intended, the latter comprises only one engaging blade, or more than two blades.

Bien entendu, l'invention ne se limite pas aux modes de réalisations décrits et représentés sur les figures, mais englobe au contraire toutes les variantes que l'homme du métier pourra déterminer.Of course, the invention is not limited to the embodiments described and shown in the figures, but on the contrary encompasses all the variants that a person skilled in the art can determine.
