The invention concerns a re-closable bag package (1) intended in particular for food products, provided with elements (11, 12) of the hook and loop coupling type to close it in such a way as to be adapted to the varying quantity of product contained therein; more precisely, the elements (11, 12) are attached to opposite sides of the package such that when the top is rolled down for closure, they are in a suitable position to couple each other and therefore close the package. In addition, by providing the elements (11, 12) with an associated adhesive side it is possible to attach them individually to the package according to a method in which the elements are advanced in a support tape and detached from it with great simplicity and speed; the invention also includes a device for carrying out the method of attaching the elements to the package.

L'invention concerne un emballage (1) se présentant sous la forme d'un sac pouvant être refermé, conçu notamment pour des produits alimentaires et pourvu d'éléments (11, 12) d'accouplement du type crochet/boucle, permettant de fermer le sac de manière que celui-ci puisse s'adapter à la quantité variable de produit qu'il contient. Plus précisément, ces éléments (11, 12) sont fixés sur les côtés opposés de l'emballage de façon que lorsque la partie supérieure de l'emballage est roulée vers le bas pour fermer celui-ci, les éléments soient dans une position appropriée à leur accouplement et ferment ainsi l'emballage. En outre, en dotant ces éléments (11, 12) d'une côté adhésif, on peut les fixer individuellement sur l'emballage selon un procédé dans lequel ces éléments sont avancés sur un ruban support, puis détachés de celui-ci très simplement et rapidement. L'invention concerne également un dispositif destiné à assurer la fixation desdits éléments sur l'emballage.
