Definitions
- the present invention relates to a machine for the continuous manufacture of tubular bodies of boxes including cardboard-based or similar, this machine comprising at least one longitudinal forming mandrel whose section corresponds to the inner section of the tubular bodies of boxes to manufacture and around which is applied and folded at least one strip of material unwound in the longitudinal direction and previously glued at least partially to form a closed tubular section, this machine further comprising pressure means arranged to laminate said at least one strip of material against said forming mandrel, and pulling means arranged to continuously move said tubular section along said forming mandrel.
- Such a machine is particularly described in the publication FR 2 702 414 whose method of manufacture provides for folding the lateral flaps of each strip of material against the forming mandrel so as to be at least partially asymmetrical, so that the folding of a first flap of a strip of material is completed before the folding of the second component of this strip of material, this folding being completed before that of a first component of a next strip of material.
- This manufacturing process makes it possible to obtain tubular bodies of boxes of very good quality, avoiding the phenomena of folding between the strips of material and by ensuring a precise geometry of the longitudinal joints so as to guarantee the desired resistance of the wall of the tube. in the area or areas where these joints are.
- the guiding and the folding of the strips of material against the forming mandrel are provided by fixed guides for example in the form of sheet metal. Then the rolling of these strips of material around the forming mandrel to ensure their intimate assembly by gluing and the longitudinal displacement of the tubular section formed by said strips of material are provided by traction belts driven and pressurized against said mandrel by motorized rigid pressure rollers, these traction belts being distributed radially around said forming mandrel.
- the present invention aims to overcome these disadvantages by providing a machine for the manufacture of tubular bodies of simpler design, representing a lesser investment, for a small footprint, facilitating maintenance operations, allowing a quick change of format of boxes to to manufacture, allowing automated start-up, thus faster with less waste of raw materials, offering better rolling of the strips of material between them making it possible to considerably improve the quality and the mechanical strength of the obtained box bodies, reducing or even eliminating friction and linear voltages to limit the power of the traction means.
- Another object of the invention is to achieve box bodies offering optimum sealing for packaging boxes that require this property.
- the invention relates to a machine of the type indicated in the preamble, characterized in that said pressure means and said traction means are distinct and in that said pressure means comprise a plurality of pressure rollers, mounted free in rotation on their axis, said pressure rollers being deformable and distributed radially around said forming mandrel so as to match the perimeter of said mandrel.
- the pressure rollers are preferably distributed symmetrically around said forming mandrel, each cover a sector of said mandrel, and are offset longitudinally so as to cover the entire perimeter of said mandrel.
- each pressure roller comprises a lining made of elastic material and having a profile complementary to that of the sector of the forming mandrel against which the corresponding pressure roller is applied.
- the elastic lining of said pressure rollers may comprise internal recesses arranged to increase its elasticity.
- the elastic material of said liner may furthermore be chosen from the group comprising natural rubbers and synthetic rubbers based on polyurethane.
- each pressure roller is carried by a support that can be adjustable in radial position relative to said forming mandrel, and is coupled to a pressurizing member embedded on said support.
- the machine according to the invention may further comprise a longitudinal centering mandrel arranged upstream of said forming mandrel and having a polygonal section whose development is inferior to the inner development of the tubular bodies of boxes to be manufactured, said centering mandrel being arranged to guiding longitudinally and transversely said strips of material without sliding.
- It may also comprise a longitudinal mandrel arranged downstream of said centering mandrel and upstream of said forming mandrel and having a drop-shaped section of water whose developed corresponds to the inner development of the tubular bodies of boxes to manufacture.
- it preferably comprises a welding station adjacent to said temporary mandrel for welding the longitudinal edges of at least one strip of material forming the inner layer of said tubular bodies of boxes.
- It may finally comprise a series of pressure rollers aligned on a longitudinal sector of said forming mandrel corresponding to an area where the longitudinal edges of said at least one strip of material meet to close said tubular section by at least one longitudinal joint.
- the traction means may comprise at least one traction belt carried by driving rollers and disposed downstream of said pressure means, and preferably at least two traction belts arranged symmetrically with respect to said forming mandrel.
- Said machine may further comprise at least one gluing nozzle arranged to add glue on at least some of the longitudinal edges of said strips of material.
- the machine 1 is partially illustrated in the accompanying figures to show only the parts concerned by the present invention, without chassis or fairing to facilitate understanding.
- This machine allows the manufacture of tubular bodies of boxes, in particular based on cardboard or the like, for example for the packaging of foodstuffs or the like, by unwinding in the longitudinal direction of one or more strips of material 2 wound in coils, said strips being glued, superimposed in plies and slightly offset laterally between them before being applied against a longitudinal forming mandrel 3 around which they are folded, pressed and rolled to form a tubular section 4 closed by one or more longitudinal joints 5 staggered .
- This tubular section 4 is then cut to form said tubular bodies of boxes to the desired dimensions.
- the longitudinal joint 5 is obtained by gluing the superposed longitudinal edges 6 of each strip of material 2, the longitudinal edges of each strip of material being preferably offset laterally so that the longitudinal joints of said strips of material overlap so as not to weaken the wall of the tubular bodies of boxes in this junction zone. If the tubular bodies of boxes are made from a single strip of material, then it is a strip of complex or composite material, that is to say formed of several layers of different materials or not. function of the physical properties that the tubular bodies of boxes must present.
- the machine 1 partially shown in the accompanying figures comprises a longitudinal forming mandrel 3 of circular section corresponding to the inner section of the tubular bodies of boxes to manufacture, which are therefore cylindrical.
- this machine 1 allows the manufacture of tubular bodies of boxes of all sections, such as polygonal, ovoid or other.
- the machine 1 according to the invention differs from known machines in that the "rolling" function of the material strips around the forming mandrel 3 and the “pulling" function of the tubular section formed by said strips of material are dissociated and made by traction means 10 and completely separate pressure means 20.
- the traction means 10 visible on the figures 1 and 3 are preferably arranged downstream of the pressure means 20, that is to say after the formation and closure of the tubular section 4 obtained by the folding and rolling of the material strips 2. They comprise one and preferably several traction belts 11 closed loop around at least two drive rollers 12, at least one is rotated by a suitable actuator such as a motor or servomotor. To ensure a uniformly distributed tensile force on the tubular section 4, four traction belts 11 distributed symmetrically about said forming mandrel 3 are used as in the example shown.
- the profile of the traction belts 11 and the drive rollers 12 is adapted and complementary to the sector of the forming mandrel 3 against which they are supported. In the example shown, this profile is cylindrical.
- the number of traction belts 11 can vary, as well as their layout, their design and their drive means.
- the pressure means 20 comprise a plurality of pressure rollers 21 mounted free to rotate about their axis, deformable and distributed radially and longitudinally around the forming mandrel 3 so as to perfectly fit the entire perimeter of the forming mandrel 3 to ensure a uniform and powerful rolling of the web of material strips 2 against the forming mandrel 3 promoting their cohesion and intimate assembly by gluing.
- Each pressure roller 21 comprises a shaft 22 carrying a lining 23 made of an elastic material, such as for example natural rubbers and synthetic rubbers based on polyurethane, having a given hardness by way of non-limiting example of about 60 Shore.
- the profile of this trim 23 is adapted and complementary to the sector of the forming mandrel 3 against which the pressure roller 21 is applied. In the example shown in Figures 5 and 6 this profile is cylindrical and its radius is less than or equal to that of the forming mandrel 3.
- the pressure rollers used may be pressing rollers 21 which are thus symmetrical, such as those illustrated in FIGS.
- FIGS. Figures 4F, 4G and 4H Their design and operation, however, remain the same.
- the pressure roller 21 When the pressure roller 21 is not pressurized against the forming mandrel 3, it defines a clearance J between its lining 23 which is not stressed and the tubular section 4 carried by the forming mandrel 3 (see FIG. Figure 5A ). When it is pressurized against the forming mandrel 3 by the means described hereinafter, its lining 23 is deformed to eliminate the clearance J and perfectly match the sector of the tubular section 4 against which it bears, the sector of the corresponding forming mandrel 3 behaving in counter-bearing part (see Figure 5B ).
- the pressure roller 21 has the advantage of providing a bearing surface limited to a generator, and therefore to a linear contact, thus making it possible to exert a greater and more uniform local pressure than in the case of a rolling surface. .
- the lining 23 may comprise internal recesses 23 'arranged to increase its elasticity.
- the pressure roller 21 is rotatably mounted on its axis and generates no friction or slippage on the tubular section 4. To reduce or eliminate the differential speeds in the end zones of the pressure roller 21, the size of these pressure rollers 21 is reduced and their number increased.
- the shank 22 of the pressure roller 21 is rotatably mounted on an axis 24 by ball bearings 25 or the like, which axis 24 is carried by a support 26.
- This support 26 comprises a plate 27 fixed to the frame (not shown) of the machine 1 of in order to be dismountable and adjustable in radial position relative to the forming mandrel 3, thus facilitating the maintenance and adjustment operations.
- This support 26 comprises a slider 28 guided in translation in the plate 27 and at the end of which is fixed said pin 24 carrying the pressing roller 21.
- This slider 28 is displaced in radial translation with respect to the forming mandrel 3 by means of a linear actuator, such as a cylinder (not shown), for applying the pressure roller 21 against the forming mandrel 3 with a defined and adjustable pressure.
- This slider 28 comprises at least two guide columns 29, located symmetrically with respect to a central rod 30 extending the linear actuator, the two columns 29 and the central rod 30 being arranged to slide in corresponding bores provided in the plate 27.
- any other equivalent means for guiding and / or pressurizing the pressure rollers 21 is conceivable.
- the machine 1 comprises a centering mandrel 40 ( Figures 2 and 4B ) longitudinal disposed upstream of the forming mandrel 3 against which are fed the strips of material 2 which are unwound from their coils, previously glued, superimposed in a sheet with a small lateral offset as explained above and moved longitudinally by the traction means 10 previously described.
- the strips of material 2 will automatically curve without a lateral guide ( Figure 4A ) since they are placed in longitudinal tension by the pulling means 10 from their unwinding zone to the forming mandrel 3 where they pass from an open state to a flat state in a closed state wound into a tubular section 4.
- the centering mandrel 40 has a polygonal section whose development is inferior to the inner development of the tubular bodies of boxes to manufacture, whose function is to guide longitudinally and transversely the web of strips of material 2 without sliding, thus, the offset side imposed between the strips of material 2 is preserved, which ensures the quality of the longitudinal junction zone of the tubular section 4 and the resistance mechanical tubular bodies of manufactured boxes.
- the shape of the centering mandrel 40 shown may be different, the main thing being to stabilize the web of strips of material 2 which begins to bend by at least one longitudinal angular zone transversely locking the strips of material 2 between them.
- a longitudinal mandrel 41 disposed downstream of the centering mandrel 40 and upstream of the forming mandrel 3 may be provided when it is necessary to weld a barrier film forming a membrane or inner layer provided in the tubular bodies of boxes to be manufactured for to respect sealing constraints.
- this temporary mandrel 41 has a section in the form of a drop of water whose developed corresponds to the internal development D of the tubular bodies of boxes to be manufactured ( Figures 2 and 4C ).
- Cylindrical pressing rollers are provided in abutment on the inclined and opposite sides of the temporary mandrel 41 to press the barrier film around said mandrel and pull it upwards to perform the welding operation by an adjacent welding station 42 chuck and using for example ultrasound or the like. If the barrier film is to be glued instead of welded, the temporary mandrel 41 is not useful. By cons, a gluing nozzle (not shown) is placed at this level to deposit glue on at least one of the longitudinal edges of said barrier film before folding with the other strips of material 2. In other cases , the tubular bodies of boxes may be devoid of barrier film.
- the sheet of material strips 2 is folded laterally by a flanging roller 43 offering a profile complementary to the provisional half mandrel 41 or centering mandrel 40 ( Figures 2 and 4D ).
- This folding roller 43 is rotatably mounted on its axis to prevent any friction on the web.
- the machine 1 can advantageously be completed by a gluing nozzle 44 arranged facing the edges longitudinals 6 offset strips of material 2 to add glue on these areas that tend to air dry.
- this gluing nozzle 44 thus makes it possible to substantially reduce the quantity of glue between the strips of material 2, which are previously glued individually in a gluing station (not shown) before being superimposed on a sheet, and consequently reduce the residual moisture of the box bodies produced.
- the fact of adding glue just before folding down the longitudinal edges 6 of the strips of material 2 has the advantage of allowing quality and uniform gluing along the entire longitudinal joint 5.
- the pressure rollers 21 forming the pressing means 20 for shaping and rolling the web of material strips 2 around said mandrel are distributed symmetrically with respect to said mandrel, its lower part ( figure 4E ) against which the sheet arrives, at its upper part ( figure 4I against which the sheet closes to form the tubular section 4.
Description
La présente invention concerne une machine pour la fabrication en continu de corps tubulaires de boîtes notamment à base de carton ou similaire, cette machine comportant au moins un mandrin de formage longitudinal dont la section correspond à la section intérieure des corps tubulaires de boîtes à fabriquer et autour duquel est appliquée et rabattue au moins une bande de matière déroulée dans le sens longitudinal et préalablement encollée au moins partiellement pour former un profilé tubulaire fermé, cette machine comportant en outre des moyens de pression agencés pour laminer ladite au moins une bande de matière contre ledit mandrin de formage, et des moyens de traction agencés pour déplacer en continu ledit profilé tubulaire le long dudit mandrin de formage.The present invention relates to a machine for the continuous manufacture of tubular bodies of boxes including cardboard-based or similar, this machine comprising at least one longitudinal forming mandrel whose section corresponds to the inner section of the tubular bodies of boxes to manufacture and around which is applied and folded at least one strip of material unwound in the longitudinal direction and previously glued at least partially to form a closed tubular section, this machine further comprising pressure means arranged to laminate said at least one strip of material against said forming mandrel, and pulling means arranged to continuously move said tubular section along said forming mandrel.
Une telle machine est notamment décrite dans la publication
Dans ce type de machine, le guidage et le rabattage des bandes de matière contre le mandrin de formage sont assurés par des guides fixes par exemple sous la forme de tôle. Puis le laminage de ces bandes de matière autour du mandrin de formage pour assurer leur assemblage intime par collage ainsi que le déplacement longitudinal du profilé tubulaire formé par lesdites bandes de matière sont assurés par des courroies de traction entraînées et appliquées sous pression contre ledit mandrin par des rouleaux presseurs rigides motorisés, ces courroies de traction étant réparties radialement autour dudit mandrin de formage.In this type of machine, the guiding and the folding of the strips of material against the forming mandrel are provided by fixed guides for example in the form of sheet metal. Then the rolling of these strips of material around the forming mandrel to ensure their intimate assembly by gluing and the longitudinal displacement of the tubular section formed by said strips of material are provided by traction belts driven and pressurized against said mandrel by motorized rigid pressure rollers, these traction belts being distributed radially around said forming mandrel.
Le document
L'inconvénient de ce type de conception réside dans les nombreuses manipulations nécessaires à la mise en route de la machine pour enfiler les bandes de matière entre les guides fixes puis entre les courroies de traction, positionner correctement les bandes de matière entre elles et autour du mandrin de formage, régler la position desdits guides fixes ainsi que la pression desdits rouleaux presseurs et la tension desdites courroies de traction. Toutes ces manipulations sont délicates à réaliser, monopolisent plusieurs opérateurs simultanément et génèrent des chutes de matière première non négligeables jusqu'à l'obtention du réglage optimal. De plus, l'utilisation de guides fixes induit une forte tension linéaire due aux frottements entre les bandes de matière en déplacement continu et les guides statiques, qu'il faut compenser par des moyens de traction performants. D'autre part, l'utilisation de courroies de traction combinées à des rouleaux presseurs présente l'inconvénient d'offrir une surface de roulement relativement étendue qui nuit à la pression locale exercée sur les bandes de matière et ne permet pas d'obtenir une pression uniforme en tout point du périmètre dudit tube, ni de s'adapter aux variations d'épaisseur des bandes de matière majoritairement réalisées à base de carton. A ces inconvénients s'ajoutent le coût d'une telle machine, son encombrement, la complexité des interventions pour changer le format des corps tubulaires de boîtes à fabriquer et pour assurer la maintenance d'une telle machine et le remplacement des pièces d'usure.The disadvantage of this type of design lies in the many manipulations required to start the machine to thread the strips of material between the fixed guides and between the traction belts, correctly position the strips of material between them and around the forming mandrel, adjust the position of said fixed guides as well as the pressure of said pressure rollers and the tension of said traction belts. All these manipulations are tricky to perform, monopolize several operators simultaneously and generate falls of raw material not insignificant until the optimal setting. In addition, the use of fixed guides induces a high linear tension due to the friction between the strips of continuously moving material and the static guides, which must be compensated by efficient traction means. On the other hand, the use of traction belts combined with pressure rollers has the disadvantage of providing a relatively wide running surface which affects the local pressure exerted on the material strips and does not make it possible to obtain uniform pressure at any point of the perimeter of said tube, nor to adapt to the variations in thickness of the strips of material mainly made from cardboard. To these drawbacks are added the cost of such a machine, its size, the complexity of interventions to change the format of the tubular bodies of boxes to be manufactured and to ensure the maintenance of such a machine and the replacement of wear parts. .
La présente invention vise à pallier ces inconvénients en proposant une machine pour la fabrication de corps tubulaires de boîtes de conception plus simple, représentant un investissement moindre, pour un encombrement réduit, facilitant les opérations de maintenance, permettant un changement rapide de format de boîtes à fabriquer, autorisant une mise en route automatisée, donc plus rapide avec moins de déchets de matières premières, offrant un meilleur laminage des bandes de matière entre elles permettant d'améliorer considérablement la qualité et la résistance mécanique des corps de boîtes obtenus, réduisant voire supprimant les frottements et les tensions linéaires permettant de limiter la puissance des moyens de traction. Un autre but de l'invention consiste à réaliser des corps de boîtes offrant une étanchéité optimale pour les boîtes de conditionnement qui nécessitent cette propriété.The present invention aims to overcome these disadvantages by providing a machine for the manufacture of tubular bodies of simpler design, representing a lesser investment, for a small footprint, facilitating maintenance operations, allowing a quick change of format of boxes to to manufacture, allowing automated start-up, thus faster with less waste of raw materials, offering better rolling of the strips of material between them making it possible to considerably improve the quality and the mechanical strength of the obtained box bodies, reducing or even eliminating friction and linear voltages to limit the power of the traction means. Another object of the invention is to achieve box bodies offering optimum sealing for packaging boxes that require this property.
Dans ce but, l'invention concerne une machine du genre indiqué en préambule, caractérisée en ce que lesdits moyens de pression et lesdits moyens de traction sont distincts et en ce que lesdits moyens de pression comportent une pluralité de galets presseurs, montés libres en rotation sur leur axe, lesdits galets presseurs étant déformables et répartis radialement autour dudit mandrin de formage de manière à épouser le périmètre dudit mandrin.For this purpose, the invention relates to a machine of the type indicated in the preamble, characterized in that said pressure means and said traction means are distinct and in that said pressure means comprise a plurality of pressure rollers, mounted free in rotation on their axis, said pressure rollers being deformable and distributed radially around said forming mandrel so as to match the perimeter of said mandrel.

Dans une forme de réalisation préférée, chaque galet presseur est porté par un support qui peut être réglable en position radiale par rapport audit mandrin de formage, et est couplé à un organe de mise sous pression embarqué sur ledit support.In a preferred embodiment, each pressure roller is carried by a support that can be adjustable in radial position relative to said forming mandrel, and is coupled to a pressurizing member embedded on said support.
La machine selon l'invention peut comporter en outre un mandrin de centrage longitudinal disposé en amont dudit mandrin de formage et présentant une section polygonale dont le développé est inférieur au développé intérieur des corps tubulaires de boîtes à fabriquer, ledit mandrin de centrage étant agencé pour guider longitudinalement et transversalement lesdites bandes de matière sans glissement.The machine according to the invention may further comprise a longitudinal centering mandrel arranged upstream of said forming mandrel and having a polygonal section whose development is inferior to the inner development of the tubular bodies of boxes to be manufactured, said centering mandrel being arranged to guiding longitudinally and transversely said strips of material without sliding.
Elle peut également comporter un mandrin provisoire longitudinal disposé en aval dudit mandrin de centrage et en amont dudit mandrin de formage et présentant une section en forme de goutte d'eau dont le développé correspond au développé intérieur des corps tubulaires de boîtes à fabriquer.It may also comprise a longitudinal mandrel arranged downstream of said centering mandrel and upstream of said forming mandrel and having a drop-shaped section of water whose developed corresponds to the inner development of the tubular bodies of boxes to manufacture.

La machine 1 selon l'invention est illustrée partiellement dans les figures annexées pour ne montrer que les parties concernées par la présente invention, sans châssis ni carénage pour faciliter la compréhension. Cette machine permet la fabrication de corps tubulaires de boîtes, notamment à base de carton ou similaire, par exemple pour le conditionnement de produits alimentaires ou similaires, par déroulement dans le sens longitudinal d'une ou de plusieurs bandes de matière 2 enroulées en bobines, lesdites bandes étant encollées, superposées en nappe et légèrement décalées latéralement entre elles avant d'être appliquées contre un mandrin de formage 3 longitudinal autour duquel elles sont rabattues, pressées et laminées pour former un profilé tubulaire 4 fermé par un ou plusieurs joints longitudinaux 5 décalés. Ce profilé tubulaire 4 est ensuite tronçonné pour former lesdits corps tubulaires de boîtes aux dimensions voulues. Le joint longitudinal 5 est obtenu par collage des bords longitudinaux 6 superposés de chaque bande de matière 2, les bords longitudinaux de chaque bande de matière étant de préférence décalés latéralement pour que les joints longitudinaux desdites bandes de matière se chevauchent afin de ne pas fragiliser la paroi des corps tubulaires de boîtes dans cette zone de jonction. Si les corps tubulaires de boîtes sont réalisés à partir d'une seule bande de matière, alors il s'agit d'une bande de matière complexe ou composite, c'est-à-dire formée de plusieurs couches de matières différentes ou non en fonction des propriétés physiques que les corps tubulaires de boîtes doivent présenter.The
La machine 1 représentée partiellement dans les figures annexées comporte un mandrin de formage 3 longitudinal de section circulaire correspondant à la section intérieure des corps tubulaires de boîtes à fabriquer, qui sont par conséquent cylindriques. Bien entendu, cette machine 1 permet la fabrication de corps tubulaires de boîtes de toutes sections, telles que polygonales, ovoïdes ou autres.The
La machine 1 selon l'invention se distingue des machines connues par le fait que la fonction « laminage » des bandes de matière autour du mandrin de formage 3 et la fonction « traction » du profilé tubulaire formé lesdites bandes de matière sont dissociées et réalisées par des moyens de traction 10 et des moyens de pression 20 totalement distincts.The
Les moyens de traction 10 visibles sur les
Les moyens de pression 20 comportent une pluralité de galets presseurs 21 montés libres en rotation autour de leur axe, déformables et répartis radialement et longitudinalement autour du mandrin de formage 3 de manière à épouser parfaitement l'ensemble du périmètre de ce mandrin de formage 3 pour assurer un laminage uniforme et puissant de la nappe de bandes de matière 2 contre le mandrin de formage 3 favorisant leur cohésion et assemblage intime par collage.The pressure means 20 comprise a plurality of
Les
Lorsque le galet presseur 21 n'est pas mis sous pression contre le mandrin de formage 3, il définit un jeu J entre sa garniture 23 qui n'est pas contrainte et le profilé tubulaire 4 porté par le mandrin de formage 3 (voir
De plus, le galet presseur 21 est monté libre en rotation sur son axe et ne génère aucun frottement ni glissement sur le profilé tubulaire 4. Pour réduire voire supprimer les vitesses différentielles dans les zones d'extrémité du galet presseur 21, la dimension de ces galets presseurs 21 est réduite et leur nombre augmenté.In addition, the
Le fût 22 du galet presseur 21 est monté libre en rotation sur un axe 24 par des paliers 25 à billes ou similaires, lequel axe 24 est porté par un support 26. Ce support 26 comporte une platine 27 fixée sur le châssis (non représenté) de la machine 1 de manière à être démontable et réglable en position radiale par rapport au mandrin de formage 3, facilitant ainsi les opérations de maintenance et de réglage. Ce support 26 comporte un coulisseau 28 guidé en translation dans la platine 27 et à l'extrémité duquel est fixé ledit axe 24 portant le galet presseur 21. Ce coulisseau 28 est déplacé en translation radiale par rapport au mandrin de formage 3 au moyen d'un actionneur linéaire, tel un vérin (non représenté), permettant d'appliquer le galet presseur 21 contre le mandrin de formage 3 avec une pression définie et réglable. Ce coulisseau 28 comporte au moins deux colonnes de guidage 29, situées symétriquement par rapport à une tige centrale 30 prolongeant l'actionneur linéaire, les deux colonnes 29 et la tige centrale 30 étant agencées pour coulisser dans des alésages correspondants prévus dans la platine 27. Bien entendu, tout autre moyen équivalent de guidage et/ou de mise sous pression des galets presseurs 21 est envisageable.The
Dans l'exemple illustré, notamment aux
Un mandrin provisoire 41 longitudinal disposé en aval du mandrin de centrage 40 et en amont du mandrin de formage 3 peut être prévu lorsqu'il est nécessaire de souder un film barrière formant une membrane ou couche intérieure prévue dans les corps tubulaires de boîtes à fabriquer pour respecter des contraintes d'étanchéité. Pour faciliter cette opération et garantir une soudure de qualité optimale, ce mandrin provisoire 41 présente une section en forme de goutte d'eau dont le développé correspond au développé intérieur D des corps tubulaires de boîtes à fabriquer (
En sortie du mandrin provisoire 41 s'il existe ou dans la continuité du mandrin de centrage 40, et en amont du mandrin de formage 3, la nappe de bandes de matière 2 est rabattue latéralement par un galet de rabattage 43 offrant un profil complémentaire au demi-mandrin provisoire 41 ou au mandrin de centrage 40 (
Dans l'exemple représenté, les galets presseurs 21, 21' sont au nombre de huit :

La série de galets presseurs 21 favorise la qualité du scellage des bords longitudinaux entre eux.

The series ofpressure rollers 21 promotes the quality of the sealing of the longitudinal edges between them.
Il ressort clairement de cette description que l'invention permet d'atteindre les buts fixés. Notamment, cette nouvelle conception permet de séquencer la fermeture des galets presseurs à la mise en route de la machine et ainsi d'automatiser le démarrage générant des gains importants. De même, les changements de format de corps tubulaires de boîtes à fabriquer sont plus rapides ainsi que les opérations de maintenance. De plus, les corps de boîtes ainsi fabriqués sont de meilleure qualité aussi bien au niveau résistance mécanique qu'au niveau des propriétés barrières.It is clear from this description that the invention achieves the goals. In particular, this new design makes it possible to sequence the closing of the pinch rollers at the start of the machine and thus to automate the start generating significant gains. Likewise, changes in the format of tubular bodies of boxes to be manufactured are faster as well as the maintenance operations. In addition, the box bodies thus manufactured are of better quality both in terms of mechanical strength and barrier properties.
