Description

Procédé de fabrication de sachets ayant un fond à soufflet. L'invention est une variante simplifiée du brevet FR-A-2.689.105 permettant de réduire la consommation de papier.Method of manufacturing bags having a bellows bottom. The invention is a simplified variant of patent FR-A-2,689,105 making it possible to reduce the consumption of paper.
Le brevet FR-A-2.689.105 concerne un sachet dont les parois sont formées d'un papier plissé suivant une direction perpendiculaire à sa base qui est munie d'un soufflet permettant de le faire tenir debout et qui permet de créer un premier volume de dosage d'une quantité de produit et notamment de frites; dans un deuxième temps, il est possible de déployer les plis qui ne sont fixés que sur les bords supérieurs du sachet pour augmenter le volume du sac et améliorer la stabilité.Patent FR-A-2,689,105 relates to a sachet whose walls are formed of pleated paper in a direction perpendicular to its base which is provided with a bellows making it possible to make it stand upright and which makes it possible to create a first volume dosing of a quantity of product and in particular of fries; in a second step, it is possible to deploy the folds which are only fixed on the upper edges of the bag to increase the volume of the bag and improve stability.
Ce produit, pour le conditionnement des frites, concurrence les sachets en carton, tels que ceux décrits dans les brevets US-A-2 821 337, US-A-2 146 308 et WO 94/02370, fabriqués à partir d'une bande de carton, voire de papier, en bobine dont on fait une gaine aplatie, les bords de la bande étant collés entre eux cuir contre chair; ensuite la gaine est découpée transversalement au sens de déroulement du papier en longueurs régulières dont une extrémité est rabattue sur elle-même et collée pour former un fond à soufflet du sachet.This product, for the packaging of fries, competes with cardboard bags, such as those described in patents US-A-2 821 337, US-A-2 146 308 and WO 94/02370, made from a strip of cardboard, or even of paper, in a reel of which a flattened sheath is made, the edges of the strip being glued together leather against flesh; then the sheath is cut transversely to the direction of unwinding of the paper in regular lengths, one end of which is folded back on itself and glued to form a bellows bottom of the bag.
L'objet de l'invention est de fabriquer en continu des sachets en carton ou en papier non plissé avec un soufflet de fond en applicant sur la bande de papier, côté chair, à intervalles réguliers au moins une bande d'enduction mince thermosoudable disposée transversalement et positionnée par rapport à une marque de repérage située côté cuir. Selon une autre caractéristique de l'invention une bande de matériau thermosoudable est déposée le long des bords longitudinaux de la bande de papier permettant de réaliser un ourlet sur l'un des bords décalé de l'ouverture des sachets .The object of the invention is to continuously manufacture sachets of cardboard or non-pleated paper with a bottom gusset by applying to the paper strip, flesh side, at regular intervals at least one thin heat-sealable coating strip arranged transversely and positioned in relation to a marking mark located on the leather side. According to another characteristic of the invention, a strip of heat-sealable material is deposited along the longitudinal edges of the paper strip making it possible to produce a hem on one of the edges offset from the opening. sachets.
Une autre caractéristique de l'invention réside dans le fait que la bande de papier enduite de matériau thermosoudable passe, avant pliage, soudure et séparation des sachets, dans un dispositif de séchage et/ou de refroidissement.Another characteristic of the invention lies in the fact that the strip of paper coated with heat-sealable material passes, before folding, sealing and separation of the sachets, through a drying and / or cooling device.
Sur les dessins :In the drawings:
La figure 1 représente une vue en perspective schématique du procédé selon une version préférée de l'invention de fabrication des sachets à soufflet.FIG. 1 represents a schematic perspective view of the method according to a preferred version of the invention for manufacturing bellows sachets.
La figure 2 représente un sachet à soufflet fabriqué suivant le procédé de l'invention.FIG. 2 represents a bellows bag manufactured according to the method of the invention.
Il suffit de partir de la technique de fabrication du sac suivant le brevet FR-A-2.689.105, de supprimer la phase de formation des plis et de plier directement la bande de papier 1 (fig.l) longitudinalement pour former un "W" 2. Ensuite il suffit de fixer le papier sur lui- même à intervalles réguliers suivant au moins une bande de fixation 3 située perpendiculairement au sens de dérou- lement de la bande de papier 1 et de faire une découpe 4 parallèlement à la bande de fixation 3 soit dans la bande de fixation 3 elle-même si elle est large, soit entre deux bandes de fixation placées côte à côte, pour former un sachet 5 (fig.2) dont les bords verticaux 6 des faces latérales 7 et 8 sont fixées entre elles chair contre chair et comportant un soufflet 9 à sa base.It is enough to start from the technique of manufacturing the bag according to patent FR-A-2,689,105, to eliminate the phase of formation of the folds and to directly fold the strip of paper 1 (fig.l) longitudinally to form a "W "2. Then it suffices to fix the paper on itself at regular intervals along at least one fixing strip 3 situated perpendicular to the direction of unwinding of the paper strip 1 and to make a cut 4 parallel to the strip of fastening 3 either in the fastening strip 3 itself if it is wide, or between two fastening strips placed side by side, to form a bag 5 (fig.2) whose vertical edges 6 of the side faces 7 and 8 are fixed together flesh against flesh and having a bellows 9 at its base.
Dans une version préférée de l'invention la fixation est une soudure réalisée à partir d'une fine couche de matériau thermosoudable 10 (fig.l) déposée sur la bande de papier 1 à l'endroit où l'on veut réaliser la soudure par un dispositif d'enduction 22. On déroule la bande de papier 1 et on applique, du côté chair 11 qui sera interne au sac 5 terminé, à intervalles réguliers au moins une bande d'enduction 12 mince, d'un matériau thermosouda- ble 10, perpendiculairement au sens 4 de déroulement du papier et on fait passer la bande de papier 1 enduite de matériau thermosoudable dans un dispositif 13 permettant soit un séchage, soit un refroidissement, suivant le type de matériau thermosoudable utilisé, de manière qu'il n'adhère pas aux parties de la machine avec lesquelles il sera en contact lors de la fabrication du sachet 5; cette bande d'enduction 12 est associée à une marque de repérage 14 située de préférence sur le côté cuir 15 de la bande de papier 1 qui est le côté destiné à l'impression et qui se retrouvera à l'extérieur du sachet 5. Cette marque de repérage 14 peut être déposée lors de l'impression de la bande de papier 1 ce qui permet aussi de faire des impressions centrées là où les bandes d'enduction 12 sont déposées en une position repérée par rapport à cette marque de repérage 14, et cette marque de repérage sert aussi à positionner l'endroit exact pour faire la soudure 3 et pour faire la coupe 4. A chacune des opérations il y a un dispositif de contrôle 16 régulier de la position de la marque de repérage 14 par rapport à la position de la bande d'enduction 12 de manière à vérifier si elle est dans la zone souhaitée de manière à déclencher, par exemple sans que cet exemple soit limitatif, une correction du positionnement de la bande d'enduction 12 dès que l'on constate une dérive.In a preferred version of the invention, the fixing is a weld produced from a thin layer of heat-sealable material 10 (fig.l) deposited on the paper strip 1 at the place where it is desired to weld a coating device 22. The strip of paper 1 is unwound and at least one thin coating strip 12 of heat-sealable material is applied at the flesh side 11 which will be internal to the finished bag 5 at regular intervals 10, perpendicular to the direction 4 of unwinding of the paper and the strip of paper 1 coated with heat-sealable material is passed through a device 13 allowing either drying or cooling, depending on the type of heat-sealable material used, so that it does not adhere to the parts of the machine with which it will be in contact during the manufacture of the bag 5; this coating strip 12 is associated with a marking mark 14 preferably located on the leather side 15 of the paper strip 1 which is the side intended for printing and which will be found outside of the bag 5. This registration mark 14 can be deposited during the printing of the paper strip 1 which also makes it possible to make prints centered where the coating strips 12 are deposited in a position marked with respect to this registration mark 14, and this marking mark also serves to position the exact place to make the weld 3 and to make the cut 4. At each of the operations there is a device 16 for regular control of the position of the marking mark 14 relative to the position of the coating strip 12 so as to check whether it is in the desired area so as to trigger, for example without this example being limiting, a correction of the positioning of the coating strip 12 as soon as that there is a drift.
Dans une variante de la version préférée de l'inven¬ tion, on dépose aussi une bande de matériau thermosoudable 10 sur les bords 17 de la bande de papier 1 et on sèche ou on refroidit comme précédemment de manière ensuite à replier les bords 17, pour former de chaque côté un ourlet longitudinal 18, permettant de les rigidifier et les rendre éventuellement moins agressifs pour les consom¬ mateurs. Dans une autre variante de la version préférée de l'invention, le matériau thermosoudable est déposé au cours d'une opération indépendante de celle concernant la fabrication du sachet, en lui associant un repère préa¬ lablement imprimé et la bande de papier est réenroulée; cette opération ne peut se faire que si la couche de pro¬ duit déposée est suffisamment mince pour permettre le réenroulage de la bande sans que la bobine ne soit défor¬ mée. La fabrication de l'ourlet longitudinal 18 précédem- ment décrit peut être aussi réalisée avec de la colle froide qui peut être déposée au cours du repliage 19 de l'ourlet longitudinal 18; cela entraîne pratiquement l'utilisation sur une même machine de deux dispositifs d'encollages différents; la fixation des bords 6 (fig.2) du sachet par des colles froides ne permet la dépose de la colle qu'après pliage longitudinal dans le conformateur permettant de réaliser le pliage en forme de "W" 2 (fig.l) ce qui est techniquement difficile à réaliser. Une autre façon de procéder consiste à utiliser une bande de papier 1 entièrement enduite de produit ther¬ mosoudable sur le côté chair 11; on peut alors supprimer le poste de dépose de la bande d'enduction 12 ou ne pas l'utiliser, et synchroniser tout simplement le poste de soudure 20 avec le poste de coupe 21; cette opération d'enduction se fait avant l'impression du papier.In a variant of the preferred version of the invention, a strip of heat-sealable material 10 is also deposited on the edges 17 of the paper strip 1 and it is dried or cooled as above so as to then fold the edges 17, to form on each side a longitudinal hem 18, making it possible to stiffen them and possibly make them less aggressive for consumers. In another variant of the preferred version of the invention, the heat-sealable material is deposited during an operation independent of that concerning the manufacture of the sachet, by associating with it a previously printed mark and the paper strip is rewound; this operation can be done if the layer of ¬ Duit deposited is thin enough to allow the rewind the tape without coil from défor¬ nted. The manufacture of the longitudinal hem 18 previously ment described can also be performed with cold glue which can be deposited during the folding 19 of the longitudinal hem 18; this practically involves the use on the same machine of two different gluing devices; fixing the edges 6 (fig.2) of the sachet with cold glues allows the glue to be deposited only after longitudinal folding in the shaping device making it possible to fold in the shape of a "W" 2 (fig.l) which is technically difficult to achieve. Another way of proceeding consists in using a strip of paper 1 entirely coated with thermosetting product on the flesh side 11; it is then possible to remove the station for depositing the coating strip 12 or not to use it, and simply synchronize the welding station 20 with the cutting station 21; this coating operation is done before printing the paper.
On a choisi pour la description une bande de papier comme matériau de base; il est évident que ce matériau peut être remplacé par un film souple quelconque simple ou complexe résistant aux températures de soudure du maté¬ riau thermosoudable 10 associé. For the description, a strip of paper was chosen as the basic material; it is obvious that this material can be replaced by any simple or complex flexible film resistant to the welding temperatures of the associated heat-sealable material 10.
