A process for finishing armoured resin products or thermoplastic resin products is characterized by applying on the surface of the resin product A at least one layer or sheet D of suitable heated thermoplastic material; applying to said layer D a pneumatic pressure to cause this to adhere integrally and evenly to the surface of the product; and cooling the whole so that, in contracting, said layer penetrates and secures itself firmly to the surface of the product. The process is particularly suitable for finishing protective helmets. <IMAGE> |
