Abstract
Apparatus and method for the continuous manufacture of structural shapes are disclosed. Mineral fiber material in the form of continuous strands, webs, or mats, impregnated with a heat-hardenable resin, is passed through a dielectric heater. The material is shaped as it passes through metallic dies that are disposed within the dielectric heater. The electric field between the electrodes of the heater is reduced or shunted at the location of the dies. The heater is arranged so that the maximum electrical field occurs adjacent the entrance to the heater.
