Abstract

On procède à l'enroulement d'une bande en matière diélectrique au moyen d'un rouleau d'enroulement entraîné sur lequel s'enroule la bande et d'un rouleau presseur exerçant une pression de contact sur la bande enroulée au point même de son arrivée sur le rouleau d'enroulement. On dispose un fil conducteur nu 12 de diamètre compris entre 0,1 et 0,3 mm en travers et parallèlement à la bande 15 à une distance de 6 à 80 mm de celle-ci sur le rouleau d'enroulement 19 dans un arc 21-22 de 0 à 90 degrés au-delà du contact 21 de la bande avec lui, et l'on applique à ce fil 12 une tension de 3000 à 10000 V sous une fréquence de 40 à 70 Hz. Application à la manutention de bandes de matière diélectrique en feuille.
