Title
(EN) DEVICE AND METHOD FOR PERFORATING WEB-LIKE MATERIALS______
(FR) DISPOSITIF ET PROCEDE POUR PERFORER DES MATERIAUX SOUS FORME DE BANDE
Abstract
(EN)
The device for the perforation of a web-like material (N) comprises a first roller (7) provided with protuberances (13), cooperating with a second roller (9), said first and said second roller being arranged along parallel axes and rotating in opposite directions forming between them a perforation nip (8) through which the web-like material (N) passes. The second roller (9) is provided with a plurality of annular projections (15) arranged in such a way that the protuberances (13) arrange themselves between contiguous annular projections (15). In this way the web-like material is pinched in the perforation nip (8) between the first roller (7) and the annular projections (15) of the second roller.
(FR)
L'invention concerne un dispositif permettant de perforer un matériau sous forme de bande (N), qui comprend un premier rouleau (7) muni de protubérances (13), qui coopère avec un second rouleau (9). Ledit premier rouleau et ledit second rouleau sont disposés le long d'axes parallèles et tournent en sens inverse et forment entre eux, un espace de perforation (8) à travers lequel passe le matériau sous forme de bande (N). Le second rouleau (9) est muni d'une pluralité de projections annulaires (15) disposées de manière que les protubérances (13) se trouvent elles-mêmes entre des projections annulaires contiguës (15). Le matériau sous forme de bande est pincé dans l'espace de perforation (8), entre le premier rouleau (7) et les projections annulaires (15) du second rouleau.
