Abstract
In a system for applying material to a substrate, a first material is applied to the substrate and the substrate coated with the first material is drawn between a pair of rollers to form a material layer. The roller which contacts the first material is grounded and an electrostatic charging device sprays electrostatically charged particles of a second material onto the roller such that the particles are evenly dispersed on the surface of the roller. The particles of the second material on the roller tend to prevent the first material from adhering to the roller and are preferably incorporated into the second material.
