  • a leader for example, a belt-like resin film for connecting the cores 5, 5A, 5B and the glass film 2 (2A to 2C) is attached to the start and end portions of the belt-like glass film 2. Also good.

Abstract

L'invention concerne un procédé de production de rouleau de verre comprenant une étape d'alimentation en film de verre consistant à distribuer un premier film de verre 2A en forme de bande dans une direction prédéterminée, une étape de formation de film consistant à former à chaud un film 3 électroconducteur transparent sur une surface 2a du premier film de verre 2A pour former un deuxième film de verre 2B, une étape d'alimentation en film protecteur consistant à superposer, sur l'autre surface 2b du deuxième film de verre 2B, un film protecteur 4 en forme de bande présentant une surface adhésive, pour former un troisième film de verre 2C et une étape d'enroulement consistant à enrouler le troisième film de verre 2C en un rouleau.
