ABSTRACT:
The apparatus has a pair of electrodes that create an electrostatic field therebetween which orients at least part of the reinforcing particles in a liquid polymeric layer so that the long dimensions of the part of the particles are disposed substantially perpendicular to the opposed flat surfaces of the layer of material, the electrodes each have a portion disposed upstream of a heating tunnel and another portion disposed in the tunnel so that the oriented particles are held in the oriented condition thereof as the heating tunnel dries the polymeric material.
