Abstract (en)
[origin: EP2353809A1] A method for producing webs perforated in a through manner, which comprises the passage of a web (13) between two counter-rotating rollers (11, 12) pressing against each other, of which a first roller (11) presents on its surface protuberances (14), which create the perforation, and a second roller (12) presents a contrast surface for said protuberances (14). The contrast surface of the second roller (12) presents contact areas (15A) for the protuberances (14) which are separated from each other by depressions (16), in which the material of the web expands.
