Abstract

DISPOSITIF D’ETIRAGE D’UN FILM ETIRABLE ET BANDEROLEUSE Le dispositif de banderolage comporte un support (4) d’un film plastique (3) et un dispositif d’étirage (A) du film plastique (3). Le dispositif d’étirage (A) comporte un premier étireur (1) alimenté par le film plastique (3) et configuré pour appliquer une première contrainte sur le film plastique (3) de manière à causer un premier allongement relatif du film plastique (3) à une première valeur d’allongement relatif. Le dispositif d’étirage (A) comporte encore un deuxième étireur (2) alimenté par le film plastique (3) provenant du premier étireur (1) et configuré pour appliquer une deuxième contrainte sur le film plastique (3) de manière à causer un deuxième allongement du film plastique (3) à une deuxième valeur d’allongement relatif. La deuxième valeur d’allongement relatif est inférieure à la première valeur d’allongement relatif. Figure pour l’abrégé : figure 2STRETCHING AND STRETCHING FILM DEVICE The wrapping device comprises a support (4) of a plastic film (3) and a stretching device (A) of the plastic film (3). The stretching device (A) comprises a first stretcher (1) fed by the plastic film (3) and configured to apply a first stress on the plastic film (3) so as to cause a first relative elongation of the plastic film (3). ) to a first relative elongation value. The stretching device (A) further comprises a second stretcher (2) supplied with the plastic film (3) coming from the first stretcher (1) and configured to apply a second stress on the plastic film (3) so as to cause a second elongation of the plastic film (3) to a second relative elongation value. The second relative elongation value is less than the first relative elongation value. Figure for the abstract: figure 2
