Abstract

L'invention concerne un procédé et une installation pour recouvrir la face cylindrique externe et les deux flancs en couronne d'un produit en forme générale de tore avec un film en matière plastique thermorétractable. Le procédé est caractérisé par le fait que, dans une première phase à température ambiante, on recouvre avec le film uniquement la face cylindrique externe du produit; dans une deuxième phase, on fait subir au film au moins un cycle d'un traitement thermique discontinu combiné à un traitement mécanique. L'installation comprend un poste pour la mise en oeuvre de la première phase du procédé et un autre poste pour la mise en oeuvre de la deuxième phase du procédé. Applicable à l'emballage de produits en forme de tore.The invention relates to a method and an installation for covering the outer cylindrical face and the two crowned sides of a product in the general shape of a torus with a heat-shrinkable plastic film. The process is characterized by the fact that, in a first phase at ambient temperature, only the external cylindrical face of the product is covered with the film; in a second phase, the film is subjected to at least one cycle of a discontinuous heat treatment combined with a mechanical treatment. The installation comprises a station for the implementation of the first phase of the method and another station for the implementation of the second phase of the method. Applicable to the packaging of torus-shaped products.
