Abstract

An apparatus and method is provided for packaging a fibrous, preferably compressible material; such as mineral fiber insulation shapes, in which the method and apparatus provides for delivering one or more such shapes (which are preferably rolls) through a staging area to a compression chamber in which they are compressed from a generally cylindrical shape or roll (or rolls) of a first diametral size, to a roll (or rolls) of a second, reduced diametral size, with the roll then being discharged from the compression chamber and being secured to substantially retain the cylindrical configuration of reduced diametral size, preferably by means of a sleeve or the like placed thereover. The operation occurs with a minimum of operator assistance, and may optionally be effected to occur automatically. The package formed may be of various roll lengths, and to this end, in the staging area prior to the compression chamber, the number of rolls that will be simultaneously compressed may be determined. Individual ones of the features are separately presented, such as the compression chamber, which employs a double stage compression, and a discharge arrangement that provides particular efficiency.

Description

Cette invention concerne l'ensachage de matières compressibles, en général fibreuses, et plus particulièrement l'ensachage de fibres minérales en rouleaux, destinées par exemple à l'isolation par fibres de verre. On devra entendre ci-dessous que, lorsqu'il est fait référence à des « rouleaux d'isolation en fibres de verre ou analogues •, une telle référence doit être considérée comme typique, non limitative, en ce sens que d'autres matières présentant des caractéristiques, en relation avec l'ensachage, semblables à celles des rouleaux d'isolation en fibres de verre pourront également être traitées avec la méthode et l'appareillage de la présente invention. Par exemple, on pourrait utiliser des poches d'isolation (de préférence sous la forme de poches à mailles larges permettant le passage de l'air durant la compression), dont les configurations pourraient être celles de coussins, ou autres, et qui, pour les fins de cette invention, sont à considérer comme suffisamment cylindriques et semblables à des rouleaux pour être traitées suivant cette invention. En outre, bien que cette invention soit utilisée de préférence pour comprimer les pièces en forme de rouleaux en cours d'emballage, la compression n'est pas une activité essentielle, en ce sens que, en fonction des dimensions de la pièce à emballer, il serait concevable de réaliser l'ensachage selon cette invention sans faire intervenir de compression.This invention relates to the bagging of compressible materials, generally fibrous, and more particularly the bagging of mineral fibers in rolls, intended for example for insulation by glass fibers. It should be understood below that, when reference is made to "glass fiber or similar insulation rolls", such a reference should be considered as typical, not limiting, in the sense that other materials having characteristics, in relation to bagging, similar to those of the glass fiber insulation rollers can also be treated with the method and apparatus of the present invention. For example, one could use insulation pockets (preferably in the form of large mesh pockets allowing the passage of air during compression), whose configurations could be those of cushions, or others, and which, for for the purposes of this invention, are to be considered sufficiently cylindrical and roller like to be treated according to this invention. In addition, although this invention is preferably used to compress the roll-shaped parts during packaging, compression is not an essential activity, in the sense that, depending on the dimensions of the part to be packaged, it would be conceivable to carry out bagging according to this invention without involving compression.

Diverses techniques ont été jusqu'ici utilisées pour l'ensachage des fibres de verre et matières analogues. Par exemple, l'utilisation d'un appareil d'ensachage pour fibres de verre en rouleaux est exposée dans le brevet US n° 3 717 973. Un autre appareil d'ensachage de fibres de verre est exposé dans le brevet US n° 3 964 232. Un autre procédé et appareillage est encore décrit dans le brevet US n° 3 458 966.Various techniques have hitherto been used for bagging glass fibers and the like. For example, the use of a bagging apparatus for glass fiber rolls is disclosed in US Patent No. 3,717,973. Another bagging apparatus for glass fibers is disclosed in US Patent No. 3 964 232. Another method and apparatus is further described in US Patent No. 3,458,966.

De même, une méthode pour transformer des matériaux compressibles en rouleau à configuration cylindrique présentant une dimension diamétrale réduite a été décrite dans le brevet français n° 1 274 007.Likewise, a method for transforming compressible materials into cylinders with a cylindrical configuration having a reduced diametral dimension has been described in French patent n ° 1 274 007.

Dans l'ensachage d'articles d'isolation réalisés à partir de rouleaux de fibres de verre, il devient de plus en plus important que l'article d'isolation, s'il est comprimé, présente un taux élevé de récupération d'épaisseur, parce que, si une telle récupération est faible, il faut un excès considérable d'épaisseur avant l'ensachage, si l'on veut obtenir l'épaisseur nominale après déballage. De même, dans certains types d'ensachage, par exemple si un rouleau de fibres de verre est disposé dans une gaine généralement imperméable à l'air, dans laquelle il est ensuite fait un vide destiné à appliquer étroitement la gaine tout autour du paquet, il est bien connu que la dimension du rouleau de fibres de verre peut être réduite, voire dans une telle mesure qu'il en est résulté fréquemment d'importantes ruptures intempestives de fibres et une compression fortement inégale, ce qui, à son tour, rend souvent le produit final au moins hautement inesthétique, si ce n'est inutilisablé.In the packaging of insulation articles made from rolls of glass fibers, it becomes increasingly important that the insulation article, if it is compressed, has a high rate of thickness recovery , because, if such recovery is low, a considerable excess of thickness is required before bagging, if the nominal thickness is to be obtained after unpacking. Likewise, in certain types of bagging, for example if a roll of glass fibers is placed in a generally airtight sheath, in which a vacuum is then created intended to apply the sheath tightly all around the package, it is well known that the size of the glass fiber roll can be reduced, or even to such an extent that this has frequently resulted in large untimely ruptures of fibers and highly uneven compression, which, in turn, makes often the end product at least highly unsightly, if not unused.

On connaît d'autres modes d'ensachage de nattes d'isolation en fibres de verre, tels qu'un emballage en couches alternées (ou emballage zig-zag), mais de tels emballages peuvent aussi entraîner des ruptures intempestives de fibres à l'emplacement des plis.Other methods of bagging glass fiber insulation mats are known, such as alternating layer packaging (or zig-zag packaging), but such packaging can also cause untimely breakage of fibers at the location of the folds.

Néanmoins, il est hautement désirable, en un certain sens, de réduire les dimensions des emballages de fibres de verre, afin de réduire les coûts de manutention, de diminuer les coûts de fret afférant au transport de grands emballages volumineux et d'obtenir une plus grande efficacité dans le stockage.Nevertheless, it is highly desirable, in a certain sense, to reduce the dimensions of the glass fiber packaging, in order to reduce the handling costs, to decrease the freight costs relating to the transport of large bulky packaging and to obtain more high efficiency in storage.

La présente invention vise à fournir une nouvelle méthode et un nouvel appareillage pour comprimer les rouleaux (y compris les pièces de forme analogues à des rouleaux) d'isolation en fibres de verre, en partant de rouleaux d'isolation en fibres de verre de forme généralement cylindriques, présentant une première dimension diamétrale, puis en comprimant ces rouleaux, de façon rigoureusement uniforme, afin d'obtenir des rouleaux de dimension diamétrale réduite, toujours de configuration généralement cylindrique. Bien que de tels rouleaux présentent la dimension diamétrale réduite, certains moyens de conservation de la dimension, tels qu'une gaine ou une poche, ou une autre structure convenable de confinement, sont appliqués sur les rouleaux, afin de les maintenir à la dimension réduite. D'autres caractéristiques particulièrement originales de la présente invention sont également proposées, telles que les différents dispositifs et mécanismes de livraison, les différents composants d'une aire de relais, dans laquelle un ou plusieurs rouleaux peuvent être sélectionnés, mis à part, ou réunis en vue d'une compression et d'un emballage simultanés, ainsi qu'une technique et un dispositif de compression particulièrement originaux.The present invention aims to provide a new method and a new apparatus for compressing rolls (including shaped parts similar to rollers) of glass fiber insulation, starting from glass fiber insulation rolls generally cylindrical, having a first diametrical dimension, then compressing these rollers, in a strictly uniform manner, in order to obtain rolls of reduced diametral dimension, always of generally cylindrical configuration. Although such rollers have the reduced diametric dimension, some means of preserving the dimension, such as a sheath or pocket, or other suitable containment structure, are applied to the rollers, in order to keep them at the reduced dimension . Other particularly original characteristics of the present invention are also proposed, such as the various delivery devices and mechanisms, the various components of a relay area, in which one or more rollers can be selected, set apart, or combined. for simultaneous compression and packaging, as well as a particularly original compression technique and device.

A cet effet on utilise un appareillage pour comprimer et ensacher des rouleaux de matière compressible de forme généralement cylindrique ou d'articles analogues comprenant une enceinte de compression présentant une première paroi mobile selon une direction parallèlement à elle-même pour réduire les dimensions, un dispositif de déchargement des rouleaux comprimés et un dispositif pour conserver aux rouleaux l'état comprimé, les maintenir et faciliter l'application de dispositifs de conservation des dimensions réduites (voir US-A-3 964 232). Selon l'invention l'appareillage est caractérisé en ce qu'il comprend un dispositif de livraison pour approvisionner l'enceinte de compression avec des jeux de rouleaux dans leurs dimensions d'origine, l'enceinte de compression ayant au moins une deuxième paroi mobile permettant la compression des rouleaux dans une deuxième direction,For this purpose, an apparatus is used to compress and bag rolls of compressible material of generally cylindrical shape or of similar articles comprising a compression enclosure having a first wall movable in a direction parallel to itself to reduce the dimensions, a device for unloading the compressed rollers and a device for keeping the compressed state in the rolls, maintaining them and facilitating the application of conservation devices of reduced dimensions (see US-A-3,964,232). According to the invention the apparatus is characterized in that it comprises a delivery device for supplying the compression enclosure with sets of rollers in their original dimensions, the compression enclosure having at least a second movable wall allowing the rollers to be compressed in a second direction,

le déplacement des deux parois aboutissant pour chaque rouleau à une configuration généralement cylindrique de dimension diamétrale réduite par rapport à celle des rouleaux d'origine.the displacement of the two walls leading, for each roller, to a generally cylindrical configuration of reduced diametral dimension compared to that of the original rollers.

Un avantage particulier de la présente invention réside en ce que le rouleau d'isolation comprimé ainsi formé est de dimension nettement réduite, avec un minimum de ruptures de fibres et avec une élimination importante des ruptures localisées de fibres, avec un haut degré de récupération d'une épaisseur uniforme, avec une réduction sensible du fret et des coûts de magasinage pour le produit final, avec des coûts réduits de manutention durant l'ensachage, et avec des coûts réduits de matériaux d'emballage, du fait qu'on emballe un rouleau plus grand, pour une grande part non comprimé.A particular advantage of the present invention lies in the fact that the compressed insulation roll thus formed is of considerably reduced size, with a minimum of fiber breaks and with a significant elimination of localized fiber breaks, with a high degree of recovery. '' a uniform thickness, with a significant reduction in freight and storage costs for the final product, with reduced handling costs during bagging, and with reduced costs of packaging materials, due to the fact that a larger roller, largely uncompressed.

Nous reportant maintenant en détail aux figures, faisons d'abord référence à la figure 1, dans laquelle l'appareil d'ensachage de la présente invention est désigné de façon générale par le numéro 10, incluant la zone d'alimentation 11, deux zones de compression 12 et 13 et deux zones 14 et 15 consacrées à l'application de gaines, de dispositifs d'ensachage ou d'autres moyens de confinement convenable pour maintenir les rouleaux comprimés dans leur état comprimé, après quoi les rouleaux sont envoyés aux zones de transporteurs d'évacuation, 16 et 17 respectivement. La zone d'alimentation 11 comporte un monte-charge ou appareil de levage 18, un appareillage transporteur latéral 20 et un appareillage transporteur longitudinal 21.Referring now in detail to the figures, let us first refer to FIG. 1, in which the bagging apparatus of the present invention is generally designated by the number 10, including the feed zone 11, two zones 12 and 13 and two zones 14 and 15 dedicated to the application of sheaths, bagging devices or other suitable confinement means to keep the compressed rollers in their compressed state, after which the rollers are sent to the zones evacuation conveyors, 16 and 17 respectively. The feed zone 11 comprises a hoist or lifting device 18, a lateral conveyor apparatus 20 and a longitudinal conveyor apparatus 21.

Nous reportant particulièrement aux figures 2 et 3, nous trouvons le monte-charge ou appareil de levage 18, qui est montré présentant à son extrémité inférieure un plateau de levage 22, conçu pour recevoir un rouleau d'isolation en fibres de verre 23 ou un article analogue, par exemple en position de roulement sur un becquet antérieur 24 dudit plateau, pour être calé entre les surfaces inclinées 25 et 26 dudit plateau.Referring particularly to Figures 2 and 3, we find the freight elevator or lifting device 18, which is shown having at its lower end a lifting plate 22, designed to receive a roll of fiberglass insulation 23 or a similar article, for example in the rolling position on an anterior spoiler 24 of said plate, to be wedged between the inclined surfaces 25 and 26 of said plate.

Le plateau 22 est porté dans un cadre mobile de guidage 27, constitué d'une traverse horizontale 28 et de deux poteaux verticaux 30 et 31 qui, à leur tour, sont contreventés par des étrésillons adéquats, 32 et 33, afin d'assurer la rigidité au cours du mouvement. Aux extrémités inférieures des poteaux verticaux 30 et 31 du cadre, il est prévu des dispositifs pivotants 34 et 35 qui s'engagent avec possibilité de rotation dans le plateau 22, en vue de permettre le mouvement de pivotement du plateau 22 par rapport au portique 27. Le portique 27 est à son tour supporté avec possibilité de mouvement vertical par rapport à un cadre fixe 36. Le cadre fixe 36 comporte des supports verticaux 37 et 38 qui jouent aussi le rôle de guides pour le déplacement avec des galets de roulement adéquats ou dispositifs analogues 40 servant à faire progresser et à guider le cadre 27 dans son mouvement vertical, tandis que les rouleaux 40 parcourent les parois guides intérieures 38' et 38".The plate 22 is carried in a movable guide frame 27, consisting of a horizontal crosspiece 28 and two vertical posts 30 and 31 which, in turn, are braced by suitable struts, 32 and 33, in order to ensure the rigidity during movement. At the lower ends of the vertical posts 30 and 31 of the frame, pivoting devices 34 and 35 are provided which engage with the possibility of rotation in the plate 22, in order to allow the pivoting movement of the plate 22 relative to the gantry 27 . The portal frame 27 is in turn supported with the possibility of vertical movement with respect to a fixed frame 36. The fixed frame 36 includes vertical supports 37 and 38 which also act as guides for movement with suitable rollers or the like 40 serving to advance and guide the frame 27 in its vertical movement, while the rollers 40 pass through the interior guide walls 38 'and 38 ".

Le mouvement vers le haut du cadre 27 et du plateau 22 au cours du levage assuré par les pivots 34 et 35 est entraîné par des cylindres de commande adéquats 41, qui peuvent être d'un type convenable quelconque, mais qui sont de préférence des cylindriques pneumatiques, destinés à déplacer le cadre 27 entre la position ad hoc en trait plein, représentée à l'extrémité supérieure de la figure 2, en assurant l'effet de levage du plateau 27, depuis la position appropriée en trait plein, représentée sur la figure 3, jusqu'à la position appropriée en pointillé, représentée à l'extrémité supérieure de la figure 3.The upward movement of the frame 27 and the plate 22 during the lifting ensured by the pivots 34 and 35 is driven by suitable control cylinders 41, which can be of any suitable type, but which are preferably cylindrical tires, intended to move the frame 27 between the ad hoc position in solid lines, shown at the upper end of FIG. 2, ensuring the lifting effect of the plate 27, from the appropriate position in solid lines, shown in the Figure 3, to the appropriate dotted position, shown at the top end of Figure 3.

Au cours du déplacement vers le haut du plateau 22, les broches basculantes 42, qui font saillie à chaque extrémité du plateau, viennent au contact de butées 43, portées par le poteau de cadre fixe 38, et empêchent la poursuite du déplacement vers le haut de l'extrémité la plus à gauche du plateau 22, ainsi qu'il est montré sur la figure 3. En conséquence, la poursuite du mouvement, vers le haut du cadre mobile 27 provoque un léger pivotement en sens inverse de celui des aiguilles d'une montre, du plateau 28 autour de l'axe de rotation 35, ce qui facilite le déchargement d'un rouleau non comprimé 23 à partir de là, dans la direction de la flèche 44 représentée sur la figure 3. Il doit être entendu que ce travail des cylindres 41 peut être programmé en vue d'une opération automatique ou analogue, si on le souhaite, ou bien peut être déclenché par un opérateur en fonction des circonstances et des opérations.During the upward movement of the plate 22, the tilting pins 42, which project at each end of the plate, come into contact with stops 43, carried by the fixed frame post 38, and prevent the continuation of the upward movement from the leftmost end of the plate 22, as shown in FIG. 3. Consequently, the continuation of the movement, upwards of the movable frame 27 causes a slight pivoting in the opposite direction to that of the needles d 'a watch, of the plate 28 around the axis of rotation 35, which facilitates the unloading of an uncompressed roller 23 from there, in the direction of the arrow 44 shown in Figure 3. It should be understood that this work of the cylinders 41 can be programmed for an automatic or similar operation, if desired, or can be triggered by an operator depending on the circumstances and the operations.

Il doit être entendu aussi que, lorsqu'il est fait référence à un rouleau 23, à ce stade de l'explication, il est sous-entendu que le rouleau est jusqu'ici non comprimé et peut, par exemple présenter un diamètre de 1 mètre ou plus. Il sera également entendu que, lorsqu'il est fait ici référence à un rouleau, le rouleau peut en fait être un « jeu de rouleaux », comportant un ou davantage de tels rouleaux mis bout à bout (longitudinalement) et, dans un tel cas, ils auront été généralement faits à partir de la même natte qui a été découpée, un ou plusieurs des rouleaux ayant été simultanément enroulés, depuis la configuration plane de natte jusqu'à une configuration de rouleau. Comme mentionné plus haut, l'article (les articles) à ensacher peuvent être initialement de formes variées, soit en poches, soit de type analogue, et il peut y en avoir un, ou bien plusieurs disposés bout à bout. Quant à leur genre, de tels articles seront référés ici comme « jeux de pièces de forme», bien qu'il soit entendu que cette invention est spécialement utilisable pour le traitement des jeux de rouleaux.It should also be understood that, when reference is made to a roller 23, at this stage of the explanation, it is understood that the roller has hitherto been uncompressed and may, for example, have a diameter of 1 meter or more. It will also be understood that, when reference is made here to a roller, the roller may in fact be a "set of rollers", comprising one or more of such rollers placed end to end (longitudinally) and, in such a case , they will generally have been made from the same mat which has been cut, one or more of the rollers having been simultaneously wound, from the flat mat configuration to a roll configuration. As mentioned above, the article (s) to be bagged may initially be of various shapes, either in pockets or of similar type, and there may be one, or several arranged end to end. As for their kind, such articles will be referred to here as “sets of shaped parts”, although it is understood that this invention is especially usable for the treatment of sets of rollers.

Ainsi donc, lorsque le rouleau ou les rouleaux sont déchargés du plateau 22 sur la zone du transporteur latéral 20 de la zone d'alimentation 11, ils arrivent sur un train supérieur 45 dudit transporteur latéral, pour être envoyés suivant la direction de la flèche 46 de la figure 3, ou de la flèche 47 de la figure 1, la bande transporteuse 45 pouvant être entraînée par une source de puissance appropriée.Thus, when the roller or rollers are unloaded from the tray 22 on the area of the lateral conveyor 20 of the feed area 11, they arrive on an upper train 45 of said lateral conveyor, to be sent in the direction of the arrow 46 of Figure 3, or of arrow 47 of Figure 1, the conveyor belt 45 can be driven by an appropriate power source.

Si le jeu de rouleaux ainsi livré comporte effectivement deux rouleaux, disposés bout à bout, mais sinon indépendants, mis à part un éventuel impact des fibres de verre de l'extrémité d'un rouleau sur les fibres du rouleau immédiatement voisin, il est possible que les rouleaux R1 et R2 viennent à se séparer, en telle sorte qu'un des rouleaux, par exemple R1' ira en avant de l'autre rouleau R2. Afin que, à la suite du déchargement depuis le plateau 22, de tels rouleaux puissent être réunis en vue de la manutention ultérieure dans une direction longitudinale, il est prévu une tringle d'alignement 48, portée par des supports verticaux convenables 51 et 52, réglables en hauteur. La fonction de la tringle d'alignement 48 consiste, dans le cas où l'un quelconque des rouleaux R1 et R2 est sorti de l'alignement, ainsi qu'il est montré sur la figure 1, en ce que le rouleau qui se déplace le plus en avant, R1' se collera, à son extrémité supérieure, contre l'extrémité inférieure 53 de la tringle, ainsi qu'il est montré sur la figure 3, jusqu'à ce que l'autre rouleau R2, se rapproche pareillement de la tringle 48. A ce moment, si le processus est contrôlé par un opérateur, le transporteur 20 peut être commandé pour entraîner les rouleaux vers la gauche, vers la zone du transporteur longitudinal 21. Si le processus est automatique, des cellules photo-électriques convenablement disposées peuvent être utilisées pour détecter l'alignement des rouleaux R1 et R2, en vue de la poursuite du transport des rouleaux le long du train supérieur 45 du transporteur 20.If the set of rollers thus delivered actually comprises two rollers, arranged end to end, but otherwise independent, apart from a possible impact of the glass fibers from the end of a roll on the fibers of the immediately neighboring roll, it is possible that the rollers R 1 and R 2 come to separate, so that one of the rollers, for example R 1 ' will go in front of the other roller R 2 . So that, after unloading from the tray 22, such rollers can be assembled for subsequent handling in a longitudinal direction, an alignment rod 48 is provided, carried by suitable vertical supports 51 and 52, adjustable in height. The function of the alignment rod 48 consists, in the event that any of the rollers R 1 and R 2 is out of alignment, as shown in FIG. 1, that the roller which moves the most forward, R 1 ' will stick, at its upper end, against the lower end 53 of the rod, as shown in Figure 3, until the other roller R 2 , similarly approaches the rod 48. At this time, if the process is controlled by an operator, the conveyor 20 can be controlled to drive the rollers to the left, towards the area of the longitudinal conveyor 21. If the process is automatic, suitably arranged photocells can be used to detect the alignment of the rollers R 1 and R 2 , with a view to continuing the transport of the rollers along the upper train 45 of the conveyor 20.

Le rouleau ou les rouleaux sont, immédiatement après, livrés à la zone du transporteur longitudinal 21 ou, comme il est montré sur la figure 3, ils tombent sur une glissière appropriée 54, puis sur le train supérieur 55 dudit transporteur, s'arrêtant contre une tringle d'arrêt réglable ad hoc 56. La tringle 56 peut être ajustable en hauteur au moyen d'un quelconque dispositif ad hoc, non représenté, en vue d'actionner une butée pour des dimensions de rouleaux de diamètres variés, et sera généralement pré-réglée pour une dimension diamétrale donnée de rouleau à traiter. °The roller or the rollers are, immediately after, delivered to the zone of the longitudinal conveyor 21 or, as shown in FIG. 3, they fall on an appropriate slide 54, then on the upper train 55 of said conveyor, stopping against an adjustable stop rod ad hoc 56. The rod 56 can be adjustable in height by means of any ad hoc device, not shown, in order to actuate a stop for dimensions of rolls of various diameters, and will generally be preset for a given diametral dimension of the roller to be treated. °

A ce moment, l'opérateur peut faire un choix, à sa convenance, selon le diamètre désiré et selon le nombre de rouleaux à inclure à l'intérieur d'un ensachage final.At this time, the operator can make a choice, at his convenience, according to the desired diameter and according to the number of rollers to be included inside a final bagging.

Se référant particulièrement à la figure 1, on notera que la zone du transporteur longitudinal 21 comporte une section généralement plus grande, 57, entraînée vers l'avant, et une section arrière 58, qui peut être entraînée au choix enReferring particularly to FIG. 1, it will be noted that the zone of the longitudinal conveyor 21 has a generally larger section, 57, driven forward, and a rear section 58, which can be driven as desired.

direction avant ou en direction inverse, ainsi qu'il est indiqué par la flèche à deux pointes 60 de la figure 1. Les deux sections de transporteur, 57 et 58, présentent entre elles une zone de séparation 61. Ainsi donc, si deux rouleaux, présentant les dimensions longitudinales générales des rouleaux représentés par la figure 1, atteignent la zone du transporteur 21, et si l'on désire ensacher seulement un rouleau de la dimension R1' l'opérateur peut amener la section de transporteur 58 à se déplacer suivant une direction inverse, soit verticalement vers le haut comme on le voit sur le plan de la page dans la figure 1, en sorte que le rouleau R2 sera maintenu sur la section de transporteur 58, conçue comme aire de relais, tandis que le rouleau R1 pourra être déplacé longitudinalement suivant la direction de la flèche 62, représentée sur la figure 1.forward direction or in reverse direction, as indicated by the two-pointed arrow 60 in FIG. 1. The two conveyor sections, 57 and 58, have between them a separation zone 61. Thus, if two rollers , having the general longitudinal dimensions of the rollers represented by FIG. 1, reach the zone of the conveyor 21, and if it is desired to bag only a roll of the dimension R 1 ′ the operator can cause the conveyor section 58 to move in a reverse direction, either vertically upwards as seen on the plane of the page in FIG. 1, so that the roller R 2 will be maintained on the conveyor section 58, designed as a relay area, while the roller R1 can be moved longitudinally in the direction of arrow 62, shown in FIG. 1.

Par contre, si l'on désire ensacher ensemble un, deux ou davantage de rouleaux Ri, R2, etc..., en un seul emballage, lorsque ces rouleaux atteindront la zone du transporteur 21, les sections 57 et 58 seront entraînées toutes deux suivant la direction de la flèche 62, en sorte que tous les rouleaux de ce genre pourront être livrés simultanément à une zone de compression 12 ou 13.On the other hand, if it is desired to bag one, two or more rolls R i , R 2 , etc., in a single package, when these rolls reach the zone of the conveyor 21, the sections 57 and 58 will be driven both in the direction of arrow 62, so that all such rollers can be delivered simultaneously to a compression zone 12 or 13.

Il ressort de ce qui précède qu'on peut adopter différents arrangements et combinaisons en ce qui concerne l'ensachage suivant les dimensions de rouleaux. Dans certains cas, plusieurs rouleaux pourront être assemblés en un seul ensachage ; dans d'autres cas, un rouleau seulement pourra être disposé dans un ensachage donné, mais la présente invention permet diverses options et offre une certaine souplesse.It appears from the above that different arrangements and combinations can be adopted with regard to bagging according to the dimensions of the rolls. In some cases, several rolls can be assembled in a single bagging; in other cases, only one roll can be placed in a given bagging, but the present invention allows various options and offers a certain flexibility.

Suivant l'emplacement d'une zone de séparation de rouleaux RB, ainsi qu'il est montré sur la figure 1, la zone de séparation 61 entre les transporteurs 57 et 58 pour la zone du transporteur 21 peut être déplacée longitudinalenent (soit vers le haut, soit vers le bas, ainsi qu'il est montré sur la figure 1), en agissant sur une poignée de manivelle 63, de sorte que la totalité de la zone du transporteur 21 puisse être déplacée suivant une direction, soit vers l'avant, soit vers l'arrière, en saisissant la manivelle 63 et en la déplaçant dans le sens des aiguilles d'une montre ou en sens inverse, afin de placer la zone de séparation 61 en diverses positions longitudinalement. Pour entraîner de la sorte la zone du transporteur 21, la manivelle 63 fera tourner un engrenage à pignons 64 porté par une structure cadre fixe 65, - l'engrenage à pignons 64 venant en prise avec les dents d'une crémaillère 66 qui est portée par une structure cadre mobile 67 de la zone du transporteur 21 et de ce fait entraîne la zone du transporteur 21 en direction longitudinale, de la façon mentionnée plus haut. Ce faisant, des roulettes de guidage appropriées 68 ou des dispositifs analogues peuvent être prévus afin d'assurer un mouvement régulier.Depending on the location of a roll separation zone R B , as shown in FIG. 1, the separation zone 61 between the conveyors 57 and 58 for the conveyor zone 21 can be moved longitudinally (either towards the top, either down, as shown in Figure 1), by acting on a crank handle 63, so that the entire area of the conveyor 21 can be moved in one direction, either towards the 'forward or backward, by grasping the crank 63 and moving it clockwise or counterclockwise, in order to place the separation zone 61 in various positions longitudinally. To thereby drive the zone of the conveyor 21, the crank 63 will rotate a pinion gear 64 carried by a fixed frame structure 65, the pinion gear 64 engaging the teeth of a rack 66 which is carried by a movable frame structure 67 of the area of the conveyor 21 and therefore drives the area of the conveyor 21 in the longitudinal direction, as mentioned above. In doing so, suitable guide rollers 68 or the like can be provided to ensure smooth movement.

Référons-nous maintenant à la figure 4, dans laquelle le rouleau ou les rouleaux (ce qui inclut le jeu de rouleaux) ont maintenant été envoyés, au moyen du transporteur 57, à un emplacement d'éjection, entre les deux zones de compression 12 et 13, ainsi qu'il est montré par le jeu de rouleaux en pointillé de la figure 4. A ce moment, le mouvement longitudinal du transporteur 57 est arrêté, soit par l'opérateur si le processus s'effectue manuellement, soit de préférence par rencontre d'un déclencheur d'arrêt convenable, tel qu'un commutateur d'extrémité ou une cellule photo-électrique P.C. La sélection est ensuite autorisée, permettant au rouleau R d'être éjecté vers l'une des zones de compression 12 ou 13. Dans le modèle représenté sur la figure 4, la zone (ou l'appareillage) 12 est celle qui est prévue pour recevoir le jeu de rouleaux R.Let us now refer to FIG. 4, in which the roller or the rollers (which includes the set of rollers) have now been sent, by means of the conveyor 57, to an ejection location, between the two compression zones 12 and 13, as shown by the set of dotted rollers in FIG. 4. At this time, the longitudinal movement of the conveyor 57 is stopped, either by the operator if the process is carried out manually, or preferably upon encountering a suitable stop trigger, such as an end switch or a photocell PC The selection is then authorized, allowing the roller R to be ejected towards one of the compression zones 12 or 13. In the model shown in FIG. 4, the zone (or the apparatus) 12 is that which is intended to receive the set of rollers R.

Tandis qu'on fait cette sélection en vue d'utiliser l'enceinte de compression 12, un cylindre 70 sera alors mis en marche, ramenant son piston 71 vers l'intérieur, et entraînant le déchargement latéral du jeu de rouleaux R en faisant pivoter un levier de poussée ou d'éjection 72 autour d'un pivot 73, de façon telle que sa tige d'éjection 74 vienne au contact de la surface cylindrique du jeu de rouleaux R lorsque l'organe d'éjection 72 est déplacé suivant la direction de la flèche 75 de la figure 4, depuis la position en trait plein de l'organe' d'éjection 72 jusqu'à la position en pointillé 74 du même organe, grâce à quoi le jeu de rouleaux R sera amené à quitter le transporteur 57, à passer sur la paroi interne 77 d'une porte frontale ouverte 78 de l'enceinte de compression 80, - la porte ouverte 78 jouant le rôle d'un plan incliné d'entrée pour le jeu de rouleaux R -, le jeu de rouleaux R passant à ses extrémités entre un couple de glissières d'entrée d'enceinte 81, de forme chanfreinée. A ce moment, la porte 78 peut être fermée, au moyen d'une cellule photo-électrique appropriée ou par intervention d'un opérateur sur un système de fermeture de porte assisté, tel qu'un cylindre à commande pneumatique 82 ou un dispositif analogue, fixé, avec possibilité de rotation comme en 83, sùr une paroi extérieure de l'enceinte 80, destiné à provoquer une rétraction du piston de commande 84, afin de fermer la porte 78, - le jeu de rouleaux R étant comprimé à l'intérieur de la cavité 85 de l'enceinte, ainsi qu'il est montré sur la figure 6. Il sera évident que, si la zone de compression 13 devait être utilisée, un levier d'éjection 72' entraînerait le jeu de rouleaux R en direction opposée -, les composants homologues relatifs à l'éjecteur 72' fonctionnant en situation miroir par rapport à ceux qui actionnent l'éjecteur 72.While this selection is made in order to use the compression enclosure 12, a cylinder 70 will then be started, bringing its piston 71 inward, and causing the lateral unloading of the set of rollers R by pivoting a push or eject lever 72 around a pivot 73, so that its ejection rod 74 comes into contact with the cylindrical surface of the set of rollers R when the ejection member 72 is moved according to the direction of arrow 75 in FIG. 4, from the solid line position of the ejection member 72 to the dotted position 74 of the same member, whereby the set of rollers R will be caused to leave the conveyor 57, to pass over the internal wall 77 of an open front door 78 of the compression enclosure 80, - the open door 78 playing the role of an inclined entry plane for the set of rollers R -, the set of rollers R passing at its ends between a pair of enclosure entry slides 81, of chamfered shape born. At this time, the door 78 can be closed, by means of a suitable photocell or by intervention of an operator on an assisted door closing system, such as a pneumatically controlled cylinder 82 or a similar device. , fixed, with the possibility of rotation as in 83, on an outer wall of the enclosure 80, intended to cause retraction of the control piston 84, in order to close the door 78, - the set of rollers R being compressed with the inside the cavity 85 of the enclosure, as shown in FIG. 6. It will be evident that, if the compression zone 13 were to be used, an ejection lever 72 ′ would cause the set of rollers R in opposite direction -, the homologous components relating to the ejector 72 'operating in a mirror situation with respect to those which actuate the ejector 72.

On verra donc que le jeu de rouleaux R est comprimé, depuis sa configuration généralement cylindrique, d'une première dimension diamétrale, comme représenté sur la figure 4, jusqu'à une configuration ovale aplatie, - ainsi qu'il est montré sur la figure 6, - qui remplit complètement la cavité 85 -, une telle compression s'exerçant entre la porte frontale 78 et la paroi arrière 86 de l'enceinte de compression.It will therefore be seen that the set of rollers R is compressed, from its generally cylindrical configuration, with a first diametrical dimension, as shown in FIG. 4, to a flattened oval configuration, - as shown in the figure 6, - which completely fills the cavity 85 -, such compression being exerted between the front door 78 and the rear wall 86 of the compression enclosure.

On notera que l'extrémité inférieure de la porte 78, ainsi qu'on le voit sur la figure 4, présente une courbe concave, comme représenté en 87, - la courbe figurant exactement le quart d'un cylindre théorique, de telle sorte que, lorsque la porte 78 est fermée en la faisant pivoter autour de l'axe 88, de la manière mentionnée plus haut, la surface incurvée 87 de la porte viendra s'ajuster à la surface incurvée de façon correspondante 90 à l'extrémité inférieure de la paroi arrière 86 de l'enceinte de compression, en sorte qu'entre les deux surfaces incurvées 87 et 90, il apparaisse une surface semi-cylindrique exactement complète.It will be noted that the lower end of the door 78, as seen in FIG. 4, has a concave curve, as shown in 87, - the curve representing exactly a quarter of a cylinder theoretical, so that when the door 78 is closed by pivoting it about the axis 88, as mentioned above, the curved surface 87 of the door will adjust to the corresponding curved surface 90 at the lower end of the rear wall 86 of the compression enclosure, so that between the two curved surfaces 87 and 90, there appears an exactly complete semi-cylindrical surface.

A ce moment, un vérin de compression 91 peut être actionné lorsque l'opérateur agit sur un couple de cylindres de commande 92 afin d'entraîner vers le bas, de façon exactement verticale, le vérin de compression 91, dans la direction des flèches 93 représentées sur les figures 4 et 5. Il sera entendu que les cylindres 92, bien qu'étant de préférence actionnés par un opérateur, peuvent également être entraînés automatiquement sous l'effet de cellules photo-elec- triques convenables, une fois que le jeu de rouleaux R est en place dans l'enceinte 85. Le vérin de compression 91 se déplace de ce fait, depuis une position telle que représentée en traits pleins à l'extrémité supérieure de la figure 5, jusqu'à la position en pointillé représentée de façon correspondante et, ce faisant, comprime le jeu de rouleaux R dans l'enceinte 85, jusqu'à une configuration cylindrique compacte, telle que représentée sur la figure 7.At this time, a compression cylinder 91 can be actuated when the operator acts on a pair of control cylinders 92 in order to drive downward, exactly vertically, the compression cylinder 91, in the direction of the arrows 93 represented in FIGS. 4 and 5. It will be understood that the cylinders 92, although preferably being actuated by an operator, can also be driven automatically under the effect of suitable photocells, once the play rollers R is in place in the enclosure 85. The compression cylinder 91 therefore moves from a position as shown in solid lines at the upper end of FIG. 5, to the dotted position shown in a corresponding manner and, in so doing, compresses the set of rollers R in the enclosure 85, to a compact cylindrical configuration, as shown in FIG. 7.

Il est évident que la surface inférieure 94 du vérin 91 est configurée de façon à adopter une géométrie généralement semi-cylindrique, exactement de la dimension finale désirée pour le jeu de rouleaux R dans son état comprimé. A cette fin, la surface 94 est relayée par des segments de surface 95 des éléments tampons 96, portés par le vérin 91. Nous référant particulièrement à la figure 8, on voit que les surfaces tampons 95 sont également incurvées en arcs afin de compléter la configuration semi-cylindrique . affectée par l'ensemble du vérin. Cependant, on notera qu'en pratique le matériau de structure du tampon 96 doit avoir généralement un faible coefficient de frottement, comme une matière thermoplastique, afin de balayer en glissant les parois verticales 77 ou 86 pendant le mouvement vertical descendant du vérin 91. En conséquence, pour faciliter la fabrication, les surfaces 95 des tampons 96 peuvent être coupées planes, d'autant plus qu'elles occupent un segment de la surface cylindrique présentant une très légère corde, en fait, l'usure aidant, elles pourront se rapprocher d'un segment en arc de cylindre. En tout cas, il est évident que, par compression du jeu de rouleaux R dans la cavité 85, ainsi qu'il est montré sur la figure 6, le matériau à base de fibres de verre sera comprimé contre les surfaces intérieures 95 des tampons 96 et les pressera, vers l'extérieur, contre les surfaces de parois 77 ou 86 de la cavité 85, et ainsi maintiendra les tampons 96 en contact à glissement serré avec les parois 77 ou 86.It is obvious that the lower surface 94 of the jack 91 is configured so as to adopt a generally semi-cylindrical geometry, exactly of the final dimension desired for the set of rollers R in its compressed state. To this end, the surface 94 is relayed by surface segments 95 of the buffer elements 96, carried by the jack 91. Referring particularly to FIG. 8, we see that the buffer surfaces 95 are also curved in arcs in order to complete the semi-cylindrical configuration. affected by the entire cylinder. However, it will be noted that in practice the material of structure of the pad 96 must generally have a low coefficient of friction, like a thermoplastic material, in order to sweep by sliding the vertical walls 77 or 86 during the vertical downward movement of the jack 91. In Consequently, to facilitate manufacture, the surfaces 95 of the pads 96 can be cut planar, all the more since they occupy a segment of the cylindrical surface having a very slight cord, in fact, wear helping, they will be able to approach of a segment in the arc of a cylinder. In any case, it is obvious that, by compression of the set of rollers R in the cavity 85, as shown in FIG. 6, the material based on glass fibers will be compressed against the interior surfaces 95 of the pads 96 and will press them, outwards, against the surfaces of walls 77 or 86 of the cavity 85, and thus will keep the pads 96 in close sliding contact with the walls 77 or 86.

A leurs extrémités supérieures, les tampons 96 sont montés au moyen de plusieurs vis à tête coiffante ou dispositifs analogues 97, logées dans les fentes verticales 98 dans les tampons 96 et solidarisées par filetages avec le vérin 91. Les fentes verticales 98 autorisent un certain jeu d'ajustement vertical, vers le haut ou vers le bas, suivant la direction de la flèche à deux pointes 100, représentée sur la figure 8. Un tel ajustement peut être effectué au moyen de plusieurs vis de réglage manuel 101, engagées par leurs filetages dans des blocs de montage 102 qui, à leur tour, sont portés par le vérin 91, - les extrémités inférieures des vis,· ainsi qu'il est montré sur la figure 8, étant, à leur tour, solidarisées de façon captive avec leurs extrémités supérieures des tampons 96, ainsi qu'il est représenté en 103. Ainsi, les tampons 96 peuvent être ajustés, généralement vers le bas, afin de compenser l'usure contre leur surface 95. Eventuellement, les tampons 96 seront remplacés lorsque l'usure deviendra trop importante et, afin de s'adapter à l'usure, les tampons portent une incision, ainsi qu'il est montré en 99.At their upper ends, the pads 96 are mounted by means of several styling head screws or similar devices 97, housed in the vertical slots 98 in the pads 96 and secured by threads with the jack 91. The vertical slots 98 allow a certain amount of play vertical adjustment, up or down, in the direction of the arrow with two points 100, shown in Figure 8. Such adjustment can be made by means of several manual adjustment screws 101, engaged by their threads in mounting blocks 102 which, in turn, are carried by the jack 91, - the lower ends of the screws, · as shown in Figure 8, being, in turn, secured captively with their upper ends of the pads 96, as shown in 103. Thus, the pads 96 can be adjusted, generally downward, in order to compensate for wear against their surface 95. Eventually, the pads 96 will be replaced during that the wear will become too great and, in order to adapt to the wear, the pads have an incision, as shown in 99.

A ce moment, le jeu de rouleau a été comprimé jusqu'à une géométrie de façon générale cylindrique, de dimension diamétrale réduite.At this time, the roller set was compressed to a generally cylindrical geometry, of reduced diametrical dimension.

Référence est maintenant faite à la figure 5, dans laquelle un cylindre pneumatique ou un dispositif analogue 105 sera généralement actionné par un opérateur, en vue d'amener un vérin de déchargement 106 à décharger d'une enceinte de compression le jeu de rouleaux comprimés R. Une telle invention peut aussi bien être automatique ou commandée par un opérateur, suivant option. Cependant, il sera en général souhaité de disposer déjà d'un organe en place pour maintenir le jeu de rouleaux comprimés à sa dimension diamétrale réduite. A cet effet, on notera qu'un compartiment avancé de décharge 107 est prévu à l'extrémité de gauche de l'enceinte de compression présentée sur la figure 5, compartiment convenablement dimensionné pour recevoir le jeu de rouleaux comprimés. Le compartiment de décharge 107 est généralement une structure tubulaire cylindrique, portée par la paroi 108 de l'enceinte de compression et il est approprié à recevoir sur lui une gaine 110, réalisée en matière thermoplastique, en papier ou autre, de préférence avec une partie 111 de la gaine faisant saillie au-delà de l'extrémité 112 du compartiment de décharge. Quand la gaine 110 est en" place, un signal peut être lancé, soit manuellement, soit au moyen d'une cellule photo-électrique appropriée (non représentée), ou d'autre façon analogue, pour signaler à l'opérateur de l'équipement qu'il est temps d'actionner le cylindre 105. Alors, le cylindre 105 enverra le vérin de déchargement 106 vers la gauche, ainsi qu'il est montré sur la figure 5, suivant la direction de la flèche 113, et le vérin de déchargement 106, guidé dans son mouvement vers la gauche par des galets appropriés 114, portés par, - et roulant contre -, la surface intérieure de la cavité 85 de l'enceinte de compression maintenant sous pression, déchargera le jeu de rouleaux comprimés R dans le compartiment de décharge 107. Il sera évident que, en fonction de la dimension longitudinale du rouleau ou des rouleaux composant le jeu de rouleaux dans la cavité 85, et en fonction de la longueur du jeu de rouleaux qui vient d'être précédemment déchargé de l'enceinte de compression, à volonté, la longueur de course pour le piston du vérin de déchargement pourra être convenablement réglée par l'opérateur ou par un signal préprogrammé avant la commande du cylindre 105.Reference is now made to FIG. 5, in which a pneumatic cylinder or a similar device 105 will generally be actuated by an operator, with a view to causing an unloading cylinder 106 to unload from a compression enclosure the set of compressed rollers R Such an invention may as well be automatic or controlled by an operator, depending on option. However, it will generally be desirable to already have a member in place to maintain the set of compressed rollers at its reduced diametrical dimension. For this purpose, it will be noted that an advanced discharge compartment 107 is provided at the left end of the compression enclosure presented in FIG. 5, compartment suitably sized to receive the set of compressed rollers. The discharge compartment 107 is generally a cylindrical tubular structure, carried by the wall 108 of the compression enclosure and it is suitable for receiving on it a sheath 110, made of thermoplastic material, paper or the like, preferably with a part 111 of the sheath projecting beyond the end 112 of the discharge compartment. When the sheath 110 is in place, a signal can be launched, either manually, or by means of an appropriate photocell (not shown), or in other similar manner, to signal the operator of the equipment it is time to activate the cylinder 105. Then the cylinder 105 will send the unloading cylinder 106 to the left, as shown in FIG. 5, in the direction of the arrow 113, and the cylinder unloading 106, guided in its movement to the left by suitable rollers 114, carried by - and rolling against -, the internal surface of the cavity 85 of the compression chamber now under pressure, will unload the set of compressed rollers R in the discharge compartment 107. It will be obvious that, depending on the dimension longitudinal of the roller or rollers making up the set of rollers in the cavity 85, and as a function of the length of the set of rollers which has just been previously discharged from the compression enclosure, as desired, the length of stroke for the piston of the unloading cylinder may be suitably adjusted by the operator or by a preprogrammed signal before ordering the cylinder 105.

De préférence, le vérin 106 présentera un plateau 116 dimensionné pour s'adapter, en situation de glissement serré, le long de la paroi cylindrique de l'intérieur de l'enceinte de compression 85, lorsque le vérin 106 progresse dans son déplacement et le plateau de glissement 106 sera aussi de préférence réalisé à partir d'une matière thermoplastique ou d'un autre matériau pouvant facilement glisser par rapport au matériau de structure de l'enceinte de compression.Preferably, the jack 106 will have a plate 116 sized to adapt, in a tight sliding situation, along the cylindrical wall of the interior of the compression enclosure 85, when the jack 106 progresses in its movement and the sliding plate 106 will also preferably be made from a thermoplastic or other material that can easily slide relative to the structural material of the compression enclosure.

De la façon la plus souhaitable, la longueur de course choisie ou pré-programmée par le vérin 106 sera de nature à pousser un premier jeu de rouleaux R au sein du compartiment de décharge 107 d'une quantité suffisante pour que la partie la plus en avant du premier jeu de rouleaux avance juste avant l'extrémité 112 du compartiment de décharge, afin d'empêcher la gaine d'être prématurément expulsée du compartiment de décharge et pour que, lorsque le vérin 106 poussera un second jeu de rouleaux R au sein du compartiment de décharge 107, ledit second jeu de rouleaux R, en avançant, contraigne le premier jeu de rouleaux comprimés R, se déplaçant vers la gauche, à entraîner avec lui l'emballage tubulaire 110, glissant vers la gauche sur la face extérieure du compartiment de décharge 107, de façon telle que l'ensemble du paquet ensaché soit envoyé sur les rouleaux transporteurs 120 d'une des zones de transporteurs 16 ou 17.Most preferably, the stroke length chosen or pre-programmed by the jack 106 will be such as to push a first set of rollers R within the discharge compartment 107 by an amount sufficient for the most before the first set of rollers advances just before the end 112 of the discharge compartment, in order to prevent the sheath from being prematurely expelled from the discharge compartment and so that, when the jack 106 pushes a second set of rollers R within of the discharge compartment 107, said second set of rollers R, moving forward, forces the first set of compressed rollers R, moving to the left, to carry with it the tubular packaging 110, sliding to the left on the outside of the discharge compartment 107, so that the entire bagged package is sent to the transport rollers 120 from one of the transport zones 16 or 17.

De ce qui précède, il ressortira que les différentes autres dispositions caractéristiques et modifications de l'appareillage apparaîtront, toutes conformes à l'esprit et à l'objet de l'invention, telle qu'elle est décrite et revendiquée. Par exemple, il sera évident que certains autres organes de confinement pourront être utilisés, au lieu de la gaine 110, pour maintenir les rouleaux déchargés à leur dimension finale, mais que certains organes seront toujours nécessaires pour emballer les rouleaux comprimés. Par exemple, dans l'esprit de la présente invention, il est concevable que des bandes d'un certain type puissent être employées, mais qu'on utilisera de préférence une gaine 110. Il est également évident que la gaine 110 pourrait comporter si on le désire une poche présentant un fond, d'un bord à l'autre de l'extrémité laissée ouverte, comme il est montré sur la figure 5. De façon analogue, il sera évident que la dimension de l'emballage final pourra varier, en fonction des limitations à la sortie tenant à l'enceinte de compression et à son compartiment de décharge. Alors que la présente invention est particulièrement destinée à fournir des ensachages pour un ou plusieurs rouleaux, elle n'est limitée à aucun diamètre particulier, ledit diamètre étant déterminé par le choix du diamètre du compartiment de décharge, par la dimension en section droite de l'enceinte de compression, etc... De même, il sera entendu que l'appareillage. peut être utilisé pour l'ensachage de pièces de forme qui seront ou non des rouleaux, mais qui ne présenteront pas une dimension transversale plus grande que le diamètre de la cavité cylindrique délimitée quand le vérin 91 est dans la position de la figure 7, et qui ne présenteront pas une dimension transversale plus grande que l'ouverture du compartiment de décharge 107, auquel cas il n'y aura en fait aucune fonction de compression effectuée par le vérin 91, ni par la fermeture de la porte 78. De même, bien que la présente invention soit principalement destinée à l'ensachage de nattes de fibres de verre mises en rouleaux, il est concevable que d'autres produits similaires puissent être utilisés, avec les même types ou avec des types similaires d'équipement, tout cela restant dans l'esprit et dans le contexte de l'invention, tels qu'ils sont définis dans les revendications exposées en Annexe.From the above, it will appear that the various other characteristic provisions and modifications of the apparatus will appear, all in accordance with the spirit and the object of the invention, as described and claimed. For example, it will be obvious that certain other containment members may be used, instead of the sheath 110, to keep the unloaded rollers at their final dimension, but that certain members will always be necessary for packaging the compressed rolls. For example, in the spirit of the present invention, it is conceivable that strips of a certain type could be used, but that a sheath 110 will preferably be used. It is also obvious that the sheath 110 could comprise if one a pocket with a bottom, from one edge to the other of the end left open, as shown in FIG. 5, desires. Similarly, it will be obvious that the size of the final packaging may vary, according to the limitations on the output relating to the compression enclosure and its discharge compartment. While the present invention is particularly intended to provide bags for one or more rollers, it is not limited to any particular diameter, said diameter being determined by the choice of the diameter of the discharge compartment, by the dimension in cross section of the 'compression enclosure, etc ... Similarly, it will be understood that the apparatus. can be used for bagging shaped parts which may or may not be rollers, but which will not have a transverse dimension greater than the diameter of the cylindrical cavity delimited when the jack 91 is in the position of FIG. 7, and which will not have a larger transverse dimension than the opening of the discharge compartment 107, in which case there will in fact be no compression function performed by the jack 91, nor by the closing of the door 78. Similarly, although the present invention is primarily intended for the bagging of glass fiber mats put in rolls, it is conceivable that other similar products can be used, with the same types or with similar types of equipment, all of this remaining in the spirit and in the context of the invention, as defined in the claims set out in the Annex.
