ABSTRACT:
A method for continuous production of corrugated sheets of fiber-reinforced thermosetting resins, wherein a web of pre-impregnated material is corrugated by moving the web on elongated carrier elements arranged at intervals side by side. These elements are advanced along an essentially horizontal path in the corrugating zone and a subsequent heating and curing zone, and by causing the web to hang down to a desired extent between adjacent carrier elements. The carrier elements may be arranged transversely or longitudinally to the advancing direction of the web in order to obtain transverse or longitudinal corrugations. The upper surface of the web may be provided with a layer of surface protecting and decorating, crushed stone material before or after the corrugation operation.
