Abstract
An apparatus is taught for draining static electrical charges build-up on a traveling web of dielectric material. The apparatus includes discharge means comprised of a metal member having one end formed into at least one needle point projection. The discharge means is connected to ground potential and mounted in close proximity to the traveling web. Responsive to concentrated static electrical charges the discharge means causes ionization of the gasses surrounding the discharge means, thereby draining the static electrical charges to the ground potential through the discharge means. The apparatus further includes means for sensing and reading the magnitude of static electrical charges drawn from the web of dielectric material and for applying the sensed information as digital signals to a manufacturing controller. The manufacturing controller uses the information to control manufacturing parameters that minimize the generation of static electrical charges during the manufacture of the dielectric material.
