La présente invention concerne un nouveau procédé pour la pose d'un film dossé et collé sur une plaque, par exemple en carton. The present invention relates to a new process for the installation of a film which is folded and glued onto a plate, for example made of cardboard.
Actuellement, il existe des caisses réalisées à partir d'une plaque, par exemple en carton comportant un ou plusieurs films-plastique associés, servant après passage dans un tunnel de rétraction, de protection et de calage pour un ou plusieurs objets contenus. Currently, there are cases made from a plate, for example of cardboard comprising one or more associated plastic films, serving after passage through a shrinking tunnel, protection and wedging for one or more contained objects.
Le film provenant d'une gaine coupée en deux, est dossé, c'est-à-dire replié sur lui-même de façon à former un feuillet inférieur posé sur la plaque de la boîte et maintenu sur celui-ci par collage, et un feuillet supérieur libre. The film coming from a sheath cut in half is wrapped, that is to say folded back on itself so as to form a lower sheet placed on the plate of the box and held on it by gluing, and a free top sheet.
Pendant les mécanisations pour le montage des caisses, dans le margeur notamment, le feuillet supérieur non maintenu, peut se décoller, se déchirer, ou se tordre. During the mechanizations for the assembly of the cases, in the feeder in particular, the unsupported upper sheet may come off, tear, or twist.
L'invention vise à résoudre ce problème. The invention aims to solve this problem.
Le problème est résolu par un procédé de pose d'un film plastique sur une plaque, par exemple mais non limitativement en carton dans le but de maintenir, ou caler, par rétraction du film, un objet à l'intérieur de la caisse conformée à partir de ladite plaque, le film étant plié en deux selon deux feuillets supérieur et inférieur, et ledit feuillet inférieur étant collé de façon permanente sur une des parties de la plaque, caractérisé en ce qu'on réalise un feuillet supérieur plus large que le feuillet inférieur de manière à coller le bord dépassant du feuillet supérieur, sur la plaque par un collage temporaire. The problem is solved by a method of laying a plastic film on a plate, for example but not limited to cardboard in order to maintain, or wedge, by shrinking the film, an object inside the box conformed to starting from said plate, the film being folded in two along two upper and lower sheets, and said lower sheet being permanently bonded to one of the parts of the plate, characterized in that an upper sheet is produced which is wider than the sheet lower so as to stick the protruding edge of the upper sheet, on the plate by temporary bonding.
De façon préférentielle mais non limitative qu'on applique au moins deux points de colle temporaire, au voisinage des deux extrémités du bord dépassant. Preferably but not limited to applying at least two points of temporary adhesive, in the vicinity of the two ends of the protruding edge.
L'invention consiste également en une plaque pour la réalisation d'une caisse dans laquelle un ou plusieurs objets sont maintenus par un film plastique plié en deux feuillets, chacun des objets étant placé entre l'un des feuillets collé sur la plaque et un autre feuillet recouvrant et calant l'objet après rétraction, caractérisé en ce que ladite plaque comporte au moins un film plastique plié en deux feuillets dont le feuillet supérieur est plus large que le feuillet inférieur, le bord dépassant du feuillet supérieur débordant d'une largeur suffisante pour lui permettre d'être collé sur la plaque, par un collage temporaire. The invention also consists of a plate for the production of a box in which one or more objects are held by a plastic film folded in two sheets, each of the objects being placed between one of the sheets glued to the plate and another sheet covering and wedging the object after retraction, characterized in that said plate comprises at least one plastic film folded in two sheets whose upper sheet is wider than the lower sheet, the edge projecting from the upper sheet projecting by a sufficient width to allow it to be glued to the plate, by temporary gluing.
De façon préférentielle mais non limitative le collage temporaire consiste en au moins deux points de colle non permanente au voisinage des deux extrémités du bord. Preferably but not limited to temporary bonding consists of at least two points of non-permanent adhesive in the vicinity of the two ends of the edge.

On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux figures annexées suivantes : figure 1 : schéma, montrant en vue de côté, le principe de pose d'un film dossé et collé sur un plaque, selon l'art antérieur, figure 2 : schéma, montrant en vue de côté le principe de pose d'un film sur une plaque, conformément à l'invention, figure 3 : schéma, montrant en vue de dessus une plaque sur laquelle est collé un film selon le principe de l'invention. The invention will be better understood with the aid of the description which follows, made with reference to the following appended figures: FIG. 1: diagram, showing in side view, the principle of laying a film taped and glued to a plate, according to the prior art, FIG. 2: diagram, showing in side view the principle of laying a film on a plate, in accordance with the invention, FIG. 3: diagram, showing in top view a plate on which a film according to the principle of the invention.
On se rapporte d'abord à la figure 1 montrant l'état de la technique. Reference is first made to FIG. 1 showing the state of the art.
Un film (a), plié en deux parties sensiblement égales comporte un feuillet inférieur (a2) dont le bord libre est maintenu sur une plaque (b) par une bande de colle (c) et dont la zone à proximité de la pliure est maintenue par deux points de colle (di, d2), et un feuillet supérieur (a,) qui reste libre. A film (a), folded into two substantially equal parts comprises a lower sheet (a2) whose free edge is held on a plate (b) by a strip of glue (c) and whose area near the fold is maintained by two dots of glue (di, d2), and an upper sheet (a,) which remains free.
On se rapporte à présent aux figures 2 et 3 de l'invention. We now refer to Figures 2 and 3 of the invention.
Le film plastique (1) est plié en deux feuillets de largeurs inégales (voir figure 2) un feuillet supérieur (la) plus large que le feuillet inférieur (1b) de manière à recouvrir celui-ci et à laisser dépasser un bord (1c) de largeur suffisante pour pouvoir être maintenu par un collage temporaire par exemple par des points de colle (6,7) non permanente (par exemple deux points), tandis que le feuillet inférieur est maintenu sur la plaque (10) par un collage permanent par exemple par une bande de colle (3) et deux points de colle (4,5). Ainsi le feuillet supérieur (1a), recouvrant l'objet est maintenu en position repliée pendant la mécanisation. The plastic film (1) is folded into two sheets of unequal widths (see FIG. 2) an upper sheet (la) wider than the lower sheet (1b) so as to cover the latter and allow an edge (1c) to protrude of sufficient width to be able to be maintained by temporary bonding, for example by dots of non-permanent glue (6,7) (for example two points), while the lower sheet is held on the plate (10) by permanent bonding by example by a strip of glue (3) and two points of glue (4,5). Thus the upper sheet (1a) covering the object is kept in the folded position during mechanization.
On comprendra que la figure 3 montre en vue de dessus un exemple de mise en oeuvre comportant un seul film dont le feuillet inférieur (1 b) est collé par une colle permanente sur un volet (8) d'une plaque (10) et dont le bord (1c) du feuillet supérieur (1a) est collé sur la face centrale (9) de la plaque (10) par un collage temporaire par exemple en deux points (6,7). It will be understood that FIG. 3 shows a top view of an exemplary implementation comprising a single film, the lower sheet (1 b) of which is glued with permanent adhesive on a flap (8) of a plate (10) and of which the edge (1c) of the upper sheet (1a) is bonded to the central face (9) of the plate (10) by temporary bonding, for example at two points (6,7).
Cette disposition n'est pas limitative, le bord (1c) pouvant par exemple être collé sur le même volet (8) que le feuillet inférieur (1b), et le collage temporaire pouvant être réalisé en plusieurs points ou en continu. This provision is not limiting, the edge (1c) can for example be glued to the same flap (8) as the lower sheet (1b), and temporary bonding can be carried out at several points or continuously.
En outre plusieurs films peuvent être posés sur une même plaque (10), selon le procédé de l'invention. In addition, several films can be placed on the same plate (10), according to the method of the invention.
La plaque peut être en carton ou tout autre matériau. The plate can be made of cardboard or any other material.
Dans le cas d'une plaque en carton le collage temporaire pourra être réalisé avec de la colle type colle blanche. In the case of a cardboard plate, temporary bonding can be carried out with white glue type glue.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
A titre d'exemple de réalisation non limitatif on peut employer une colle blanche référence LATYL, SONANDEL (marque déposée) à base de copolymère d'éthylène vinylacétate pour le collage temporaire, et une colle référence SAVAEX Y 45 (marque déposée), colle aqueuse à base d'homopolymère pour le collage permanent. By way of nonlimiting exemplary embodiment, a white adhesive reference LATYL, SONANDEL (registered trademark) based on ethylene vinyl acetate copolymer can be used for temporary bonding, and an adhesive reference SAVAEX Y 45 (registered trademark), aqueous adhesive. Homopolymer based for permanent bonding.
Parmi les avantages de l'invention, on peut citer une suppression des plis et des torsions, et/ou des arrachages lors des mécanisations, une meilleure qualité du calage et de la protection, et une amélioration du rendement. Among the advantages of the invention, mention may be made of the elimination of folds and twists, and / or tearing off during mechanization, better quality of wedging and protection, and an improvement in efficiency.
