Abstract

L'invention concerne l'alimentation d'un appareil élargisseur au moyen d'une nappe de pellicule. La pellicule est introduite dans l'appareil entre des courroies transporteuses disposées de chaque côté et est ainsi engagée dans des pinces de rives de l'appareil élargisseur. Dans le cas d'un défaut de fonctionnement de l'appareil, la pellicule peut être déviée vers un poste de décharge en attendant que la réparation ait été effectuée. L'invention s'applique à la fabrication de pellicules thermoplastiques orientées et durcies à chaud.
