Abstract
A charge-removing device intended to eliminate electrostatic charge from a thin dielectric strip, and in particular a rolled dielectric film. The device comprises at least two electrically conductive rolls (4,5) forming electrodes which are subjected to a potential difference by a low frequency high tension source. These rolls are parallel and come into transverse contact at the same time with respective faces of a thin strip dielectric (1) passing therebetween. The invention is applicable, in particular, to electrostatic type printers.
