Description
<Desc/Clms Page number 1>
Procède et dispositif pour la.réalisation d'une liaison entre la partie supérieure et la partie inférieure d'une botte en matière synthétique thermoplastique.
On sait réaliser des boites en matière synthétique en feuille dans lesquelles la partie supérieure de la boite, par exemple le couvercle à bords plats, repose sur un bord pareille- ment plat de la partie inférieure de la boite, par exemple sur le corps de la boite. Les parties supérieures et inférieures de telles bottes sont composées soit ensemble d'une feuille unique et sont alors reliées par un pli afin de pouvoir 'être ouvertes ou fer- mées, ou elles sont composées de parties distinctes qui sont ras- semblées par des agrafes ou toute autre pièce de liaison. On uti- lise pour clore fermement les boites des agrafes, des rivets ou
<Desc/Clms Page number 2>
leurs équivalents ou l'on colle, scelle ou soude les boites.
Ces modes de fermetures sont cependant mal commodes en regard du. résultat obtenu. Dans l'utilisation ils sont de ce fait entre.aux,,,?; très peu pratiques, car il est fréquentent nécessaire pour l'eu- ,' verture, d'utiliser un outil à main ou en l'absence d'un tel outil, on aboutit à un arrachement non satisfaisant de la boite. En outre, les bottes ne peuvent plus être fermement closes par la suite.
Les agrafes utilisées dans les bottes en deux parties ou les au- très éléments de liaison constituent des charnières dont l'action n'est pas satisfaisante en regard de la dépense engagée en matière et en travail.
L'objet de l'invention est un procédé pour la confection ou la réalisation d'un lien avantageux entre les rebords plats superposés des parties supérieures et inférieures de boîtes en feuilles de matière plastique. L'invention a encore pour objet la création d'un dispositif pour la mise en oeuvre du procédé.
On réalise de façon relativement simple selon l'invention une liaison utilisable à.répétitions entre les rebords des par- ties supérieures et inférieures d'une boite, lorsque les deux parties à rebord plat reposent l'une sur l'autre, en chauffant le rebord plat des parties supérieure et inférieure du côté où l'ouverture et la fermeture doit s'effectuer jusqu'au ramollisse- ment de la matière thermoplastique et en enroulant le rebord chauf- fé de la partie supérieure avec le rebord chauffé de la partie inférieure et en effectuant l'enroulement à au moins 180 .
Si l'enroulement est destiné à servir à des fermetures et ouvertures répétées, les rebords ne doivent pasêtre enroulés sur plus de 360 et avantageusement aux environs de 270 .Si l'enroulement doit servir de charnière entre la partie supérieure et inférieure, on enroule le rebord dans ce but sur au moins'3600. L'enroulement est effectué de telle sorte que le diamètre extérieur atteigne quelques millimètres c'est-à-dire qu'il soit par exemple compris entre 3 et 8 mm.
<Desc/Clms Page number 3>
Du fait de l'exécution commune de l'enroulement, la feuille qui se trouve à l'extérieur au cours de l'enroulement pré- sente un diamètre quelque peu supérieur et de là est enroulée moins fort que le rebord de la feuille située à l'intérieur de l'enroulement. Les limites ou dimensions d'enroulement données ci-dessus concernent la feuille la plus fortement enroulée.
Du fait que l'on enroule simultanément les rebords des deux parties de la botte et que l'on respecte les limites d'en- roulement données ci-dessus, on obtient des fermetures à rouleaux et des charnières à rouleaux très commodément utilisables.
Il convient de remarquer particulièrement que les ferme- tures à rouleaux réalisées comme ci-dessus constituent une fer- meture relativement sûre à l'égard d'ouvertures involontaires mais qui ne présentent aucune difficulté à ouvrir. Il est aussi particulièrement avantageux que l'on puisse pratiquement fermer aussi souvent que l'on veut après avoir ouvert le fermoir et réciproquement.
Le dispositif de fermeture selon l'invention peut être adapté à toutes les bottes fermant à pression qui sont confection-.
. nées en feuilles de matière synthétique thermoplastique raide ou dure. Par exemple, on considère dans ce cas les feuilles en poly- éthylène de haute densité, en polypropylène, en polystyrol,en acétate de cellulose et chlorure de polyvinyle qui ne contiennent que peu ou pas de plastifiant et dénommés PVC-durs.
L'enroulement des rebords des parties supérieure et infé-' rieure peut être'entrepris avec tout outil approprié à cet usage, comme par exemple avec un crochet de fil métallique approprié à cet usage,que l'on passe sur les rebords chauffés. L'usage d'une filière d'étirage formant un canal allongé qui est formé à partir d'une fente rectiligne qui se transforme progressivement en un alésage cylindrique est particulièrement avantageux.Un exemple sera décrit ci-après.

L'invention est expliqua dans ce qui luit en regard des dessins annexés. Les figures 1,2 et 3 représentent un dispo- sitif pour réaliser l'enroulement du procédé selon l'invention en vues de face, en plan et de cote. La Fig.4 représente une par- tie de ce dispositif à plus grande échelle, et les figures 5 à 7 quelques coupes effectuées dans la pièce représentée dans la Fig.4 et repérées par les signes V- V et VI- VI et VII - VII. Les
Figs.8 à 10 représentent un dispositif de réalisation d'enroulé- ment de fermeture'et de charnières à rouleaux selon l'invention en vues de face, en plan et latérale. Les Figs.ll et 12 montrent des coupes d'une boite avant et après exécution de l'enroulement de fermeture.
Les Figs.13, 14, 16 et 17 représentent des coupes , de deux bottes respectivement avant et après exécution de la fer- meture et des enroulements de charnières. Les Figs.15 et 18 sont des vues en plan des boites représentées dans les Figs.14 et 17.
Le dispositif représenté dans les Figs.1 à 7 sert au rabattement simultané des parties des rebords 6a et 6b des par- ties supérieure et inférieure de la boite représentée en coupe dans la Fig.ll, qui est prévu pour la réalisation d'une fermeture.
L'ouverture et la fermeture de la boite doivent s'effectuer au tour du pli creux 7. La Fig.12 représente la coupe de la botte après le rabattement de la fermeture. Afin d'effectuer le rabatte- ment, on utilise un dispositif ou une installation fonctionnant en continu. Cette installation contient une bande transporteuse sans fin @ mûe par un entraînement 1 et garnie de taquets d'en- traînement 3 . Les bottes à remborder sont amenées en position de fermeture sur la bande transporteuse 2 et déplacées au moyen des taquets d'entraînement 3.
Les parties supérieure et inférieure de la botte sont fermement maintenues l'une sur l'autre par des guides latéraux 4a et 4c et par un guide supérieur.4b, ce qui assure une trajectoire rectiligne de la botte au cours de son transport par les taquets d'entraînement 3. Les rebords 6a et
<Desc/Clms Page number 5>
6b àrabattre pénètrent ensuite dans un dispositif de chauffage
5a. Celui-ci consiste en un bloc métallique qui comporte une tente rectiligne 14 au-dessus et au-dessous de laquelle se trouvent deux canaux de chauffage 11.
Le bloc 5a est porté, par des sour- ces de chaleur insérées dans les canaux de chauffage 11, telles que par exemple des résistances de chauffage électrique, à une . ' température si élevée que les rebords de la botte 6a et 6b à rabattre atteignent du fait de leur passage dans la fente 14 une température si élevée qu'ils deviennent facilement déformables et peuvent prendre après refroidissement une forme nouvelle et la conserver. La.température dans le bloc 5a est d'autre part maintenue suffisamment basse pour que la vitesse de passage . prévue dans la fente 14 pour les rebords 6a et 6b n'aboutisse pas à les souder ensemble. Le chauffage est pratiquement réglé par un régulateur de température automatique.Après chauffage, les rebords 6a et 6b chauds atteignent la partie ou zone de formage.
Elle consiste en un bloc 5b qui comporte comme le bloc
5a une tente et deux alésages qui sont prévus pour recevoir un chauffage et le cas échéant comporte un autre alésage pour loger un régulateur de température.Le bloc 5b présente en outre un alésage cylindrique 12 qui est disposé tangentiellement à l'extré- mité de la tente 14 qui se trouve à l'intérieur de la forme
5b. L'alésage 12 est cependant de biais et se rapproche tout au long de l'ouverture de la fente de l'autre extrémité de la fen- te 14. Sa largeur diminue le long du bloc 5b dans la mesure ou l'alésage 12 se rapproche de l'ouverture de la fente.
Le calibre de l'alésage 12 correspond à la dimension ou grandeur désirée pour l'enroulement. Du fait de la disposition de biais d'un côté et tangentielle de l'autre de l'alésage 12 par rapport à la fente 14, l'enroulement des rebords 6a et 6b pré- chauffés se produit lors de l'avance de la boite dans le dispositif de formage 5b spontanément au calibre de l'alésage 12. Selon la mesure dans laquelle le biais de l'alésage 12 a rétréci progressive-

ment la fente 14, on obtient un enroulement plus ou moins pronon- ce 9 des rebords 6a et 6b.
Les rebords 6a et 6b sont laissés à refroidir après le roulage. Une zone ou appareil de refroidissement 5c est commode- ment prévue derrière l'appareil de formage 5b. Il peut être muni d'un alésage 13 dans lequel peut passer un élément réfrigérant,
Les Figs.8 à 10 représentent un dispositif grâce auquel on peut réaliser aussi bien une fermeture à rebord roulé qu'une charnière roulée simultanément à la partie supérieure et inférieure d'une botte en deux parties. Deux exemples de telle botte en deux parties sont représentés dans les Fige-13 et 16.
Dans ces botte les rebords 6a et 6b sont transformés en fermeture roulée 9 et les rebords 6c et 6d sont transformés en charnière à rouleaux
10 (fig.14, 15, 17 et 18). Ce dispositif de rembordage double ou des deux côtés présente à la différence du dispositif à simple' bordage au lieu d'un rail de guidage latéral 4a un deuxième dispo- sitif de formage 5 comprenant une partie chauffante 5a, une par- tie de formage 5b et une partie réfrigérante 5c.

Method and device for la.réalisation of a connection between the upper part and the lower part of a boot made of thermoplastic synthetic material.
It is known to produce boxes of synthetic material in sheet form in which the upper part of the box, for example the cover with flat edges, rests on a similarly flat edge of the lower part of the box, for example on the body of the box. box. The upper and lower parts of such boots are either made together of a single sheet and are then joined by a fold so that they can be opened or closed, or they are made up of separate parts which are joined together by staples. or any other connecting piece. To firmly close the boxes, staples, rivets or

their equivalents where the boxes are glued, sealed or welded.
These closure methods are however inconvenient with regard to. obtained result. In use they are therefore between.aux ,,,?; very impractical, because it is often necessary for the eu-, 'verture, to use a hand tool or in the absence of such a tool, this results in unsatisfactory tearing of the box. In addition, the boots can no longer be firmly closed afterwards.
The staples used in the two-part boots or the au- very connecting elements constitute hinges whose action is not satisfactory with regard to the expenditure incurred in terms of material and labor.
The object of the invention is a process for making or making an advantageous connection between the superimposed flat edges of the upper and lower parts of boxes made of plastic sheets. Another subject of the invention is the creation of a device for implementing the method.
A relatively simple way according to the invention is produced a connection which can be used repeatedly between the edges of the upper and lower parts of a box, when the two flat-rimmed parts rest on each other, by heating the container. flat rim of the upper and lower parts on the side where opening and closing is to take place until the thermoplastic material has softened and wrapping the heated rim of the upper part with the heated rim of the lower part and performing the winding at least 180.
If the winding is intended to be used for repeated closings and openings, the edges should not be rolled over more than 360 and preferably around 270. If the winding is to serve as a hinge between the upper and lower part, the edges should be wound up. ledge for this purpose on at least'3600. The winding is carried out so that the outside diameter reaches a few millimeters, that is to say that it is for example between 3 and 8 mm.
<Desc / Clms Page number 3>
By virtue of the common execution of the winding, the sheet which lies on the outside during the winding has a somewhat larger diameter and hence is wound less tightly than the edge of the sheet situated at the end. inside the winding. The wrap limits or dimensions given above are for the most heavily rolled sheet.
Due to the simultaneous winding of the edges of the two parts of the boot and the observance of the wrap limits given above, very conveniently usable roller closures and roller hinges are obtained.
It should be particularly noted that the roller closures made as above constitute a relatively secure closure against unintentional openings but which present no difficulty in opening. It is also particularly advantageous that one can practically close as often as one wishes after having opened the clasp and vice versa.
The closure device according to the invention can be adapted to all pressure-closing boots which are made up.
. made of sheets of stiff or hard thermoplastic synthetic material. For example, we consider in this case the sheets of high density polyethylene, polypropylene, polystyrene, cellulose acetate and polyvinyl chloride which contain little or no plasticizer and called PVC-hard.
Winding of the edges of the upper and lower portions can be undertaken with any tool suitable for this purpose, such as, for example, a hook of wire suitable for this purpose, which is passed over the heated edges. The use of a drawing die forming an elongated channel which is formed from a rectilinear slot which gradually transforms into a cylindrical bore is particularly advantageous. An example will be described below.
<Desc / Clms Page number 4>
The invention is explained in what appears with reference to the accompanying drawings. FIGS. 1, 2 and 3 represent a device for carrying out the winding of the method according to the invention in front, plan and side views. Fig. 4 represents a part of this device on a larger scale, and figures 5 to 7 a few cross-sections made in the part shown in Fig. 4 and identified by the signs V- V and VI- VI and VII - VII. The
Figs. 8 to 10 show a device for producing a closing winding and roller hinges according to the invention in front, plan and side views. Figs. 11 and 12 show sections of a box before and after execution of the closing winding.
Figs. 13, 14, 16 and 17 show cross sections, of two bundles respectively before and after execution of the closing and of the hinge windings. Figs. 15 and 18 are plan views of the boxes shown in Figs. 14 and 17.
The device shown in Figs. 1 to 7 serves for the simultaneous folding of the parts of the flanges 6a and 6b of the upper and lower parts of the box shown in section in Fig. 11, which is intended for the realization of a closure. .
The opening and closing of the box must be made around the box pleat 7. Fig.12 shows the cut of the boot after the closing of the closure. In order to effect the folding back, a continuously operating device or installation is used. This installation contains an endless conveyor belt @ moved by a drive 1 and fitted with drive cleats 3. The bundles to be rolled up are brought into the closed position on the conveyor belt 2 and moved by means of the drive lugs 3.
The upper and lower parts of the boot are held firmly to each other by side guides 4a and 4c and an upper guide 4b, which ensures a straight path of the boot during its transport by the cleats drive 3. The flanges 6a and

5a. This consists of a metal block which has a rectilinear tent 14 above and below which there are two heating channels 11.
The block 5a is carried, by heat sources inserted in the heating channels 11, such as for example electric heating resistors, to one. 'temperature so high that the edges of the boot 6a and 6b to be folded up reach, as a result of their passage through the slot 14, a temperature so high that they become easily deformable and can take on a new shape after cooling and keep it. The temperature in the block 5a is also kept low enough for the speed of passage. provided in the slot 14 for the flanges 6a and 6b does not result in welding them together. The heating is practically regulated by an automatic temperature regulator. After heating, the hot edges 6a and 6b reach the forming part or zone.
It consists of a block 5b which has like the block
5a a tent and two bores which are provided to receive a heater and optionally has a further bore to house a temperature regulator. The block 5b further has a cylindrical bore 12 which is disposed tangentially at the end of the tent 14 which is inside the form

The size of the bore 12 corresponds to the dimension or size desired for the winding. Due to the oblique arrangement on one side and tangential to the other of the bore 12 with respect to the slot 14, the winding of the preheated flanges 6a and 6b occurs during the advance of the box. in the forming device 5b spontaneously to the caliber of the bore 12. Depending on the extent to which the bias of the bore 12 has gradually narrowed-
<Desc / Clms Page number 6>
In the slot 14, a more or less pronounced winding 9 of the flanges 6a and 6b is obtained.
The flanges 6a and 6b are left to cool after rolling. A cooling zone or apparatus 5c is conveniently provided behind the forming apparatus 5b. It can be provided with a bore 13 in which a cooling element can pass,
Figs. 8 to 10 show a device by which it is possible to achieve both a rolled-edge closure and a rolled hinge simultaneously at the upper and lower part of a two-part boot. Two examples of such a two-part boot are shown in Figs-13 and 16.
In these boots the edges 6a and 6b are transformed into a rolled closure 9 and the edges 6c and 6d are transformed into a roller hinge
10 (fig. 14, 15, 17 and 18). This double or two-sided edging device has, unlike the single-edging device instead of a lateral guide rail 4a, a second forming device 5 comprising a heating part 5a, a forming part 5b. and a cooling part 5c.
