Abstract

L'invention concerne un dispositif de production manuelle ou mécanisée d'un matériau d'emballage tubulaire à partir d'une bande de papier enroulée en un rouleau, qui forme un espace creux intérieur duquel peut être tirée la bande de papier en vue de former le matériau d'emballage, comprenant un logement destiné à envelopper au moins partiellement le rouleau sur sa circonférence et un élément de maintien axial destiné à maintenir un côté frontal du rouleau. L'élément de maintien axial possède une paroi dans laquelle est formée une ouverture de sortie servant à délivrer le matériau d'emballage dans une direction axiale de sortie. La paroi possède un contour intérieur de guidage qui se rétrécit à la manière d'un entonnoir, dans la direction axiale de sortie, du logement vers l'ouverture de sortie et la paroi est pourvue d'au moins un évidement axial avant au niveau d'une extrémité de l'élément de maintien axial, à l'avant dans la direction axiale de sortie, ledit évidement s'étendant sur au moins 10 mm dans la direction axiale de sortie à partir de l'extrémité avant de l'élément de maintien axial.
