Abstract

L'invention concerne une courroie de presse pour onduleuse qui comprend un textile tissé sans fin (20) servant de couche centrale ou de base, ledit textile tissé étant imprégné du matériau élastomérique (21) dans lequel il est encapsulé. Le côté papier du matériau élastomérique est muni d'un revêtement ou d'une fine couche (22) d'un matériau (en polymère fluoré p. ex.) résistant à la contamination. Ce revêtement ou ce matériau élastomérique peut inclure un matériau antistatique.
