  • means for guiding and injecting said wire or said sheath to the desired length in order to bring the free end to the level of the edge of the film,
  • a welding-cutting assembly making it possible to cut the desired length of wire or sheath determined by said guide means and to weld it to the film.

On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :

  • la figure 1 est un schéma en élévation latérale d'un dispositif conforme à l'invention pour la mise en oeuvre du procédé conforme à l'invention ;
  • la figure 2 est une vue de dessus du schéma de la figure 1.
The invention will be better understood using the description given below of an embodiment given by way of nonlimiting example, with reference to the appended drawings in which:
  • Figure 1 is a side elevational diagram of a device according to the invention for implementing the method according to the invention;
  • Figure 2 is a top view of the diagram in Figure 1.

On a représenté à la figure 1 un film (1) avec un surfilm (2) disposé sur celui-ci de manière séquentielle, comme représenté à la figure 2.FIG. 1 shows a film (1) with a surfilm (2) arranged thereon sequentially, as shown in FIG. 2.

Ce film défile en tension dans le cadre d'une machine de conformation d'un film en coussins de matière souple remplis de liquide, comme indiqué précédemment.This film scrolls in tension as part of a machine for shaping a film into cushions of flexible material filled with liquid, as indicated above.

Pour y rapporter un moyen de préhension et/ou de versage, selon l'invention, on prévoit :

  • un magasin (3) d'alimentation en fil ou gaine, muni d'un système d'entrainement (4) de type connu,
