Abstract

Printed sheets emerging from a printer or copier are received by pairs of wheels (30, 32) which are rotating at the paper speed. A detector (34) senses the leading and trailing edges of each sheet of paper and slows down speed control wheels (36, 38) such that the paper drops into a pile (16). An electromagnet vibrates the sides of the pile container (48) to produce good alignment and the paper then passes to jaws (64, 66) which rotate to a vertical position. From this position horizontal jaws (68, 70) take over and convey the paper to a gluing roller and covering station. <IMAGE>

Description

La présente invention concerne une machine de finition pour des feuilles imprimées délivrées individuellement en succession rapide par une machine de reproduction telle qu'une imprimante ou copieuse et pour leur confection en fascicule, livret ou brochure.The present invention relates to a finishing machine for printed sheets delivered individually in rapid succession by a reproduction machine such as a printer or copier and for making them into a booklet, booklet or brochure.

Les imprimantes modernes sont à même de produire des reproductions, page par page, à des cadences très rapides allant jusqu'à plus de cent pages par minute et davantage. Au lieu de reproduire toujours la même page dans un cycle de travail, comme c'est le cas avec les copieuses ou avec les imprimantes offset, ces machines produisent successivement des jeux complets de pages d'un ouvrage, qui doit souvent être confectionné en fascicule, livret ou brochure.Modern printers are able to produce reproductions, page by page, at very fast rates of up to more than a hundred pages per minute and more. Instead of always reproducing the same page in a work cycle, as is the case with copying machines or with offset printers, these machines successively produce complete sets of pages of a work, which often has to be made up in a booklet , booklet or brochure.

Pour la confection de piles de feuilles en fascicule, livret ou brochure, des machines de finition sont certes disponibles. Lorsqu'on souhaite présenter le fascicule, le livret ou la brochure dans une couverture, ces machines de finition comportent une station d'encollage et d'emboîtage dans laquelle une pile de feuilles est d'abord encollée sur une tranche par passage sur un rouleau tournant plongé partiellement dans une colle liquide, et la couverture est ensuite appliquée contre la tranche encollée de la pile et pliée autour de celle-ci. Compte tenu de l'irrégularité avec laquelle les feuilles se présentent dans une pile, et pour obtenir des bords proprement alignés du produit fini, on est ensuite amené à découper les bords de la pile de feuille et de sa couverture. Le produit fini ne présente donc plus les dimensions des feuilles telles qu'elles sortent de la machine de reproduction, par exemple en format DIN 4. Par ailleurs, les piles de feuilles sont chargées manuellement dans la machine de finition, ce qui suppose non seulement un assemblage préalable par piles des jeux de feuilles sortant de la machine de reproduction, mais aussi une intervention humaine pour le transport de chaque pile assemblée dans la machine de finition.Finishing machines are certainly available for making stacks of sheets in a booklet, booklet or brochure. When you want to present the booklet, the booklet or the brochure in a cover, these finishing machines include a gluing and nesting station in which a stack of sheets is first glued onto a wafer by passing over a rotating roller partially immersed in liquid glue, and the cover is then applied against the glued edge of the stack and folded around it. In view of the irregularity with which the sheets appear in a stack, and in order to obtain properly aligned edges of the finished product, it is then necessary to cut the edges of the sheet stack and of its cover. The finished product therefore no longer has the dimensions of the sheets as they come out of the reproduction machine, for example in DIN 4 format. Furthermore, the stacks of sheets are loaded manually in the finishing machine, which not only requires a prior assembly by piles of the sets of sheets leaving the reproduction machine, but also human intervention for the transport of each assembled pile in the finishing machine.

La machine de finition selon la présente invention obvie à tous ces inconvénients. Suivant l'invention, la machine de finition comporte en succession: une station de prise en charge des feuilles délivrées par la machine de reproduction; un dispositif de ralentissement contrôlé des feuilles reçues de la station de prise en charge; une station d'empilage à plat des feuilles ralenties; des moyens d'alignement des feuilles en pile; un dispositif de serrage de la pile de feuilles alignées; un dispositif de rotation de la pile serrée d'une position à plat en une position sur chant; et un dispositif d'encollage d'une tranche de la pile et/ou d'emboîtage de la pile dans une couverture. Par cette combinaison de moyens et dispositifs éventuellement connus en soi, on obtient une ligne de production continue et entièrement automatique depuis la machine de reproduction jusqu'à une station terminale qui peut être une station de collecte du produit fini. Si l'on tient compte de la vitesse avec laquelle les feuilles sortent de la machine de reproduction, par exemple 1 mètre par seconde ou davantage, ce résultat est tout à fait remarquable. En effet, à une telle vitesse d'avancement, les feuilles se comportent de manière pratiquement aléatoire à moins de leur imposer un guidage forcé. Aussi, pour empiler les feuilles ainsi éjectées, il faut d'abord les ralentir. Pour empiler les feuilles dans de bonnes conditions permettant un alignement correct dans la pile, l'invention prévoit un ralentissement contrôlé des feuilles. Par un ralentissement contrôlé des feuilles, on entend dans ce contexte une décélération pratiquement identique pour chaque feuille à partir d'une vitesse de départ jusqu'à une vitesse réduite déterminée, permettant aux feuilles de se superposer correctement dans une pile, de telle sorte qu'il suffit alors d'employer des moyens simples pour aligner les feuilles dans la pile. Puisque l'invention prévoit ensuite l'utilisation d'un dispositif de serrage de la pile de feuilles alignées, même lors de la rotation de la pile d'une position à plat en une position sur chant, l'alignement correct des feuilles dans la pile est conservé. Dans l'ensemble, ces mesures permettent d'abord d'établir et puis de conserver un alignement correct des feuilles dans la pile jusqu'à la station d'emboîtage, ce qui rend superflue toute opération de découpage pour ajuster les bords du produit fini.The finishing machine according to the present invention overcomes all these drawbacks. According to the invention, the finishing machine comprises in succession: a station for taking care of the sheets delivered by the reproduction machine; a device for controlled slowing down of the sheets received from the pick-up station; a flat stacking station for slowed sheets; means for aligning the stacked sheets; a device for clamping the stack of aligned sheets; a device for rotating the stack clamped from a flat position to an edge position; and a device for gluing a section of the stack and / or for nesting the stack in a cover. By this combination of means and devices possibly known per se, a continuous and fully automatic production line is obtained from the reproduction machine to a terminal station which may be a collection station for the finished product. If you take into account the speed with which the leaves come out of the reproduction machine, for example 1 meter per second or more, this result is quite remarkable. In fact, at such a forward speed, the sheets behave in a practically random manner unless they are forced to be guided. Also, to stack the leaves thus ejected, they must first be slowed down. To stack the sheets in good conditions allowing correct alignment in the stack, the invention provides a controlled slowing down of the sheets. By a controlled slowing down of the sheets is meant in this context a practically identical deceleration for each sheet from a starting speed to a determined reduced speed, allowing the sheets to be superimposed correctly in a stack, so that 'then it is enough to use simple means to align the sheets in the stack. Since the invention then provides for the use of a device for clamping the stack of aligned sheets, even when the stack is rotated from a flat position to an edge position, the correct alignment of the sheets in the stack is retained. On the whole, these measures allow first of all to establish and then to maintain a correct alignment of the sheets in the stack up to the casing station, which eliminates any cutting operation to adjust the edges of the finished product. .

Dans une forme de réalisation préférée, on prévoit un alignement des feuilles de la pile non seulement lors de la formation de celle-ci, mais aussi après sa rotation en une position sur chant. En effet, lors du transfert de la station d'empilage vers le dispositif de rotation de la pile, l'alignement des feuilles peut être légèrement perturbé. En outre, lorsque la pile de feuilles se trouve en position sur chant, la gravité peut être exploitée pour améliorer la précision d'alignement. Dans chaque cas, l'alignement s'effectue de préférence en deux sens, c'est-à-dire en direction frontale et dans une direction transversale par rapport à la direction d'avancement des feuilles.In a preferred embodiment, an alignment of the sheets of the stack is provided not only during the formation of the latter, but also after its rotation into a position on edge. In fact, when transferring from the stacking station to the stack rotation device, the alignment of the sheets may be slightly disturbed. In addition, when the stack of sheets is in edge position, gravity can be exploited to improve alignment accuracy. In each case, the alignment is preferably carried out in two directions, that is to say in the frontal direction and in a direction transverse with respect to the direction of advancement of the sheets.

Suivant un aspect important de l'invention, on prévoit un dispositif de ralentissement de feuilles reçues individuellement et à cadences rapides en vue de leur empilage, en particulier, mais non exclusivement, dans une machine de finition du type décrit ci-dessus. Ce dispositif comporte au moins une paire de rouleaux entre lesquels chaque feuille est engagée dès sa réception; l'un des rouleaux est entraîné par un moteur à vitesse contrôlée, en particulier un moteur pas à pas commandé de façon telle que la vitesse de rotation des rouleaux correspond à la vitesse d'avancement des feuilles au moment de leur engagement entre les rouleaux, et est réduite à une fraction de cette vitesse au moment de la libération de la feuille par les rouleaux. De préférence, le moteur pas à pas tourne à vitesse réduite en régime d'attente d'une feuille et est accéléré dès la détection de l'arrivée d'une feuille. Dans ce cas, un détecteur de feuilles étant agencé en amont des rouleaux et à distance de ceux-ci, l'accélération du moteur pas à pas est déclenchée lors de la détection du bord avant d'une feuille par le détecteur, et la phase de ralentissement de la feuille est déclenchée lors de la détection du passage de son bord arrière sur le détecteur. Grâce à cette configuration, le moteur pas à pas n'est pas sollicité lorsqu'il est en régime d'attente, et la commande du moteur pas à pas est largement facilitée par le fait que la décélération de la feuille est toujours déclenchée par le passage de son bord arrière sur le détecteur, la commande étant donc indépendante de la longueur de la feuille.According to an important aspect of the invention, a device is provided for slowing down sheets received individually and at rapid rates with a view to stacking them, in particular, but not exclusively, in a finishing machine of the type described above. This device comprises at least one pair of rollers between which each sheet is engaged upon receipt; one of the rollers is driven by a speed-controlled motor, in particular a stepping motor controlled so that the speed of rotation of the rollers corresponds to the speed of advancement of the sheets at the time of their engagement between the rollers, and is reduced to a fraction of this speed when the sheet is released from the rollers. Preferably, the stepping motor rotates at reduced speed while waiting for a sheet and is accelerated as soon as the arrival of a sheet is detected. In this case, a sheet detector being arranged upstream of the rollers and at a distance therefrom, the acceleration of the stepping motor is triggered when the front edge of a sheet is detected by the detector, and the phase sheet slowing is triggered upon detection of the passage of its rear edge on the detector. Thanks to this configuration, the stepping motor is not stressed when it is in standby mode, and the control of the stepping motor is greatly facilitated by the fact that the deceleration of the sheet is always triggered by the passage of its rear edge over the detector, the control therefore being independent of the length of the sheet.

Pour améliorer la précision d'alignement de la couverture par rapport aux feuilles de la pile, l'invention propose encore de prévoir un dosage précis de la quantité de colle utilisée pour chaque fascicule, livret ou brochure. Plus précisément, l'invention prévoit que la station d'emboîtage comporte un rouleau tournant d'encollage plongé partiellement dans une colle liquide et un racleur commandé sélectivement entre une position de retrait et une position d'engagement de la surface du rouleau pour accumuler une masse de colle qui est présentée à la tranche d'une pile de feuilles lorsqu'elle passe sur chant par dessus le rouleau tournant. Le dosage de la masse de colle est déterminé par la commande du racleur en fonction du mouvement de la pile et de son épaisseur.To improve the accuracy of alignment of the cover relative to the sheets of the stack, the invention also proposes to provide a precise dosage of the quantity of glue used for each booklet or booklet. More specifically, the invention provides that the casing station includes a rotating gluing roller partially immersed in a liquid adhesive and a scraper selectively controlled between a withdrawal position and an engagement position of the surface of the roller to accumulate a mass of glue which is presented to the edge of a pile of sheets when it passes over the edge of the rotating roller. The dosage of the adhesive mass is determined by the control of the scraper according to the movement of the pile and its thickness.

Dans l'exemple décrit, la machine de finition suivant l'invention est accollée à une imprimante 10 d'un type connu, capable de fournir plus de cent pages imprimées à la minute.In the example described, the finishing machine according to the invention is attached to a printer 10 of a known type, capable of supplying more than one hundred printed pages per minute.

Les feuilles imprimées sortent de cette machine à une vitesse supérieure à 1 mètre par seconde. La première station de la machine de finition est une station 12 de prise en charge des feuilles délivrées par l'imprimante 10. Cette station 12 est suivie par un dispositif 14 de ralentissement des feuilles reçues de la station 12. Après ralentissement contrôlé des feuilles par le dispositif 14, les feuilles sont empilées dans une station 16 d'empilage à plat. Chaque pile de feuilles passe alors par une table de transfert 18 vers un dispositif de rotation 20 qui délivre chaque pile de feuilles en position sur chant, après rotation d'un angle de 90° autour d'un axe horizontal, à une station d'emboîtage 22, orientée perpendiculairement à l'alignement de l'imprimante 10 et des unités 12 à 20 de la machine de finition. Cette station d'emboîtage sera décrite plus en détail dans la suite de l'exposé.The printed sheets come out of this machine at a speed greater than 1 meter per second. The first station of the finishing machine is a station 12 for handling the sheets delivered by the printer 10. This station 12 is followed by a device 14 for slowing down the sheets received from the station 12. After controlled slowing of the sheets by device 14, the sheets are stacked in a flat stacking station 16. Each stack of sheets then passes through a transfer table 18 to a rotation device 20 which delivers each stack of sheets in edge position, after rotation of an angle of 90 ° around a horizontal axis, at a station of casing 22, oriented perpendicular to the alignment of the printer 10 and the units 12 to 20 of the finishing machine. This casing station will be described in more detail in the following description.

Comme il ressort plus clairement de la figure 2, la station 12 de prise en charge des feuilles délivrées par l'imprimante 10 comporte plusieurs paires de rouleaux de transport 30, 32 qui tournent à une vitesse correspondant essentiellement à la vitesse d'avancement des feuilles reçues de l'imprimante 10. A la sortie de cette station 12, un détecteur 34 détecte le passage de chaque feuille. Plus particulièrement, ce détecteur 34 délivre un premier signal lors de la détection du bord avant d'une feuille et un second signal lors de la détection du bord arrière d'une feuille. Les feuilles passent ensuite dans le dispositif 14 de ralentissement contrôlé. Ce dispositif est essentiellement constitué de deux paires de rouleaux 36, 38 dont l'un, 38, est commandé en rotation par un moteur pas à pas 40 à travers une courroie dentée 42. Comme il ressort du diagramme de la figure 2a, le moteur pas à pas 40 entraîne les rouleaux 38 normalement à une vitesse basse v1, en régime d'attente d'une feuille. Lorsqu'au moment t1 le détecteur 34 détermine le passage du bord avant d'une feuille, le moteur 40 est accéléré pour entraîner les rouleaux 38 à une vitesse v2 largement supérieure, correspondant essentiellement à la vitesse d'avancement des feuilles. Dans le diagramme de la figure 2a, cette vitesse v2 est atteinte au moment t2. Le bord avant de la feuille s'engage entre les rouleaux 36, 38, et la feuille est avancée à la vitesse v2 jusqu'au moment t3 où le passage du bord arrière de la feuille est déterminé par le détecteur 34. Cet évènement déclenche un ralentissement contrôlé du moteur à pas 40 jusqu'à ce que les rouleaux 38 tournent à la vitesse réduite v1. Cette vitesse v1 est suffisamment basse pour que les feuilles, lorsqu'elles sont libérées par les rouleaux 36, 38 au moment t4, tombent correctement et en chute libre dans la station 16 d'empilage.As can be seen more clearly from FIG. 2, the station 12 for handling the sheets delivered by the printer 10 comprises several pairs of transport rollers 30, 32 which rotate at a speed corresponding essentially to the speed of advancement of the sheets received from the printer 10. At the exit from this station 12, a detector 34 detects the passage of each sheet. More particularly, this detector 34 delivers a first signal when the front edge of a sheet is detected and a second signal when the rear edge of a sheet is detected. The sheets then pass through the controlled slowdown device 14. This device essentially consists of two pairs of rollers 36, 38 one of which, 38, is controlled in rotation by a stepping motor 40 through a toothed belt 42. As can be seen from the diagram in FIG. 2a, the motor step by step 40 drives the rollers 38 normally at a low speed v1, while waiting for a sheet. When at time t1 the detector 34 determines the passage of the front edge of a sheet, the motor 40 is accelerated to drive the rollers 38 at a speed v2 much higher, essentially corresponding to the leaf advance speed. In the diagram of FIG. 2a, this speed v2 is reached at time t2. The front edge of the sheet engages between the rollers 36, 38, and the sheet is advanced at speed v2 until time t3 when the passage of the rear edge of the sheet is determined by the detector 34. This event triggers a controlled slowdown of the step motor 40 until the rollers 38 rotate at the reduced speed v1. This speed v1 is low enough that the sheets, when released by the rollers 36, 38 at time t4, fall correctly and fall freely in the stacking station 16.

Comme il ressort de la figure 3, les rouleaux 36 sont profilés pour légèrement déformer la feuille F et de ce fait en augmenter la rigidité lors de son passage dans le dispositif de ralentissement vers la station d'empilage. Cette action est généralement appelée "tuilage".As shown in Figure 3, the rollers 36 are shaped to slightly deform the sheet F and thereby increase the rigidity during its passage through the slowing device to the stacking station. This action is generally called "tiling".

Dans la station d'empilage 16 représentée plus en détail dans la figure 4, les feuilles F sont empilées sur un plateau 44 pourvu d'une butée fixe arrière 46 et associé à une butée frontale de taquage 48, actionnée par un électro-aimant 50 pour aligner les feuilles F contre la butée 46 par un mouvement de battement en direction de cette butée. Simultanément, les feuilles F sont alignées par une butée de taquage latéral 52, également actionnée par un électro-aimant (non représenté). Comme il ressort également de la figure 4, la butée 48 de taquage frontal est escamotable pour permettre l'avancement de la pile de feuilles F lorsqu'elle est complète. L'escamotage de la butée 48 de taquage frontal est commandé à travers un mécanisme à bielle par un moto-réducteur 54.In the stacking station 16 shown in more detail in FIG. 4, the sheets F are stacked on a tray 44 provided with a fixed rear stop 46 and associated with a front jogging stop 48, actuated by an electromagnet 50 to align the sheets F against the stop 46 by a flapping movement towards this stop. Simultaneously, the sheets F are aligned by a lateral jogging stop 52, also actuated by an electromagnet (not shown). As also appears from FIG. 4, the front jogging stopper 48 is retractable to allow the stack of sheets F to advance when it is complete. The retraction of the front jogging stopper 48 is controlled through a connecting rod mechanism by a geared motor 54.

La table de transfert 18 est pourvue de deux fentes longitudinales parallèles permettant le passage de taquets d'entraînement 56 fixés à une courroie sans fin 58. La courroie sans fin 58 est traînée autour de deux rouleaux de renvoi 60 et 62 disposés en dessous de la table de transfert 18. Pour avancer une pile complétée dans la station d'empilage 16, l'un des rouleaux 60, 62 est entraîné en rotation pour amener l'un des taquets 56 contre le bord arrière de la pile de feuilles F et la pousser en direction du dispositif de rotation 20 vers une butée frontale 65. La pile de feuilles F glisse donc sur la table de transfert 18 jusqu'à la butée frontale 65.The transfer table 18 is provided with two parallel longitudinal slots allowing the passage of driving cleats 56 fixed to an endless belt 58. The endless belt 58 is dragged around two idler rollers 60 and 62 arranged below the transfer table 18. To advance a completed stack into the stacking station 16, one of the rollers 60, 62 is rotated to bring one of the tabs 56 against the rear edge of the stack of sheets F and push it in the direction of the rotation device 20 towards a front stop 65. The stack of sheets F therefore slides on the transfer table 18 as far as the front stop 65.

Le dispositif de rotation 20 comporte une paire de mâchoires 64, 66 susceptibles d'engager et de serrer entre elles une pile de feuilles F reçue de la station d'empilage 16. Les mâchoires 64, 66 sont montées dans une unité tournante dont l'axe de rotation A est horizontal et perpendiculaire à la direction d'avancement à la pile de feuilles. Comme schématiquement indiqué à la figure 2, le dispositif de rotation 20 tourne chaque pile de feuilles F d'un angle de 90° pour la mettre dans une position sur chant. Dans cette position, la pile de feuilles F est transférée à la station d'emboîtage 22 où la pile de feuilles F est prise en charge par une deuxième paire de mâchoires 68, 70. Après engagement des mâchoires 68, 70, les mâchoires 64, 66 peuvent être desserrées pour permettre l'avancement de la pile de feuilles F dans une direction perpendiculaire à la direction d'avancement sur les unités 12 à 20 de la machine. A cet effet, les mâchoires 68, 70 sont montées sur un chariot mobile de la station d'emboîtage. Ces éléments étant connus en soi, ils ne seront ni décrits ni représentés plus en détail.The rotation device 20 comprises a pair of jaws 64, 66 capable of engaging and clamping between them a stack of sheets F received from the stacking station 16. The jaws 64, 66 are mounted in a rotating unit, the axis of rotation A is horizontal and perpendicular to the direction of travel of the stack of sheets. As shown schematically in Figure 2, the rotation device 20 rotates each stack of sheets F by an angle of 90 ° to put it in a position on edge. In this position, the stack of sheets F is transferred to the casing station 22 where the stack of sheets F is supported by a second pair of jaws 68, 70. After engagement of the jaws 68, 70, the jaws 64, 66 can be loosened to allow advancement of the stack of sheets F in a direction perpendicular to the direction of advancement on the units 12 to 20 of the machine. To this end, the jaws 68, 70 are mounted on a mobile carriage of the casing station. These elements being known per se, they will neither be described nor shown in more detail.

La pile de feuilles F est ensuite avancée sur une table vibrante 72 où les mâchoires 68, 70 sont temporairement relâchées. La table vibrante 72 est associée à une butée frontale 74 solidaire de la mâchoire 70 qui est fixe sur le chariot de transfert, cette butée 74 permettant de corriger l'alignement frontal des feuilles. Puisque les feuilles de la pile reposent sur chant sur la table vibrante 72, leur alignement est assisté par gravité.The stack of sheets F is then advanced on a vibrating table 72 where the jaws 68, 70 are temporarily released. The vibrating table 72 is associated with a front stop 74 secured to the jaw 70 which is fixed on the transfer carriage, this stop 74 making it possible to correct the front alignment of the sheets. Since the sheets of the stack rest on edge on the vibrating table 72, their alignment is assisted by gravity.

Après nouvel alignement des feuilles F de la pile sur la table vibrante 72, la pile est avancée, toujours en position sur chant, vers une station d'encollage 76, en passant sur une unité de fraisage 78 qui travaille la tranche inférieure de la pile de feuilles F pour faciliter la prise de la colle. De manière bien connue, la station d'encollage 76 comporte un rouleau tournant 80 partiellement plongé dans un bain de colle liquide 82 contenu dans un bac 84. Un racleur mobile 86 est associé à la surface périphérique du rouleau 80, de manière également connue en soi. Toutefois, suivant une particularité de l'invention, les mouvements du racleur 86 sont commandés de façon très précise en vue d'un dosage correct de la quantité de colle à appliquer sur la tranche de la pile de feuilles F lorsqu'elle passe sur le rouleau tournant 80. Puisque la colle intervient dans le volume du dos d'un livret ou fascicule avec couverture, sa quantité a une influence non négligeable sur l'alignement de la couverture par rapport aux feuilles de la pile, après emboîtement de celle-ci dans la couverture.After new alignment of the sheets F of the stack on the vibrating table 72, the stack is advanced, still in edge position, towards a gluing station 76, passing over a milling unit 78 which works the lower edge of the stack sheets F to facilitate the setting of the adhesive. As is well known, the gluing station 76 comprises a rotating roller 80 partially immersed in a bath of liquid glue 82 contained in a tank 84. A mobile scraper 86 is associated with the peripheral surface of the roller 80, also in known manner. oneself. However, according to a feature of the invention, the movements of the scraper 86 are controlled very precisely for a correct dosage of the amount of adhesive to be applied to the edge of the stack of sheets F when it passes over the turning roller 80. Since the glue intervenes in the volume of the back of a booklet or booklet with cover, its quantity has a significant influence on the alignment of the cover with respect to the sheets of the stack, after nesting of the latter in the cover.

Lorsque le bord du racleur 86 est reculé de la périphérie du rouleau tournant 80, la colle forme une couche mince, mais d'épaisseur constante à la périphérie du rouleau. Par contre, lorsque le bord du racleur 86 est en prise avec la périphérie du rouleau 80, la colle s'accumule en 88 devant le racleur et est empêchée de former une couche à la périphérie du rouleau. Lorsque le racleur 86 est à nouveau retiré, la colle 88 forme de nouveau une couche à la périphérie du rouleau 80. La quantité de colle appliquée sur la tranche de la pile de feuilles F lorsqu'elle passe par dessus le rouleau 80, est donc déterminée par la durée de retrait du racleur 86. La durée de retrait du racleur 86 est notamment commandée en fonction de l'épaisseur de la pile de feuilles. Quant à la commande du moment auquel le racleur 86 est engagé, celle-ci est déterminée par le mouvement même de la pile lorsque celle-ci est amenée par le chariot mobile de la station, toujours serrée entre les mâchoires 68, 70.When the edge of the scraper 86 is moved back from the periphery of the rotating roller 80, the adhesive forms a thin layer, but of constant thickness at the periphery of the roller. On the other hand, when the edge of the scraper 86 is engaged with the periphery of the roller 80, the adhesive accumulates at 88 in front of the scraper and is prevented from forming a layer at the periphery of the roller. When the scraper 86 is again removed, the glue 88 again forms a layer at the periphery of the roll 80. The quantity of glue applied to the edge of the stack of sheets F when it passes over the roll 80, is therefore determined by the duration of removal of the scraper 86. The duration of removal of the scraper 86 is in particular controlled as a function of the thickness of the stack of sheets. As for the control of the moment at which the scraper 86 is engaged, this is determined by the very movement of the stack when the latter is brought by the mobile carriage of the station, always clamped between the jaws 68, 70.

Le résultat de ce dosage de colle est illustré à la figure 6. On voit que la colle, représentée par une hachure sur la tranche de la pile, n'est pas abondante. Elle laisse libre une extrémité de la tranche, compte tenu du fait qu'après l'application de la couverture, la colle aura été étalée pour couvrir cette zone.The result of this dosage of glue is illustrated in FIG. 6. It can be seen that the glue, represented by a hatching on the edge of the stack, is not abundant. It leaves one end of the wafer free, taking into account that after the application of the cover, the glue will have been spread to cover this area.

Après emboîtement de la pile encollée dans une couverture et pressage du dos du fascicule ou livret par une autre paire de mâchoires, la confection du produit est terminée. Puisque l'alignement correct des feuilles est conservé même jusque dans la station d'emboîtage, aucune opération de découpe n'est nécessaire.After fitting the glued stack into a cover and pressing the back of the booklet or booklet with another pair of jaws, the product is finished. Since the correct alignment of the sheets is preserved even up to the casing station, no cutting operation is necessary.

L'opération d'emboîtage même étant bien connue en soi, elle ne sera pas décrite en détail.The nesting operation itself being well known per se, it will not be described in detail.
