摘要

Continuous process for the manufacture of corrugated sheets based on reinforced plastic material particularly polyester-glass fiber characterized in that the support is unwrapped from a coil being sent directly between two pressing cylinders on which is distributed the resin suitable for hot hardening transported there from a tank by means of compressed air in sufficient quantity to completely fill all the interstices and to form the compact sheet that is requested by the cylinders of the continuous machine that is completely enclosed in a suitably conditioned chamber whose cylinders print the sheet with transverse corrugations in the sense of its advance while the polymerization is carried out at an adjustable temperature thereafter the hardened and corrugated sheet of the chamber leaves and is subjected to the cutting of the edges by circular saws and winding in a coil.
