A process and apparatus for forming thermoplastic products having precise embossed surfaces including using a continuous press (40) having upper and lower belts (50, 52) with the embossing patterns thermoplastic material through the press (40) where heat and pressure are applied and thereafter cooling the material while maintaining pressure in a reaction zone (53). Pressure is maintained at about 250 psi, heating is at about 480 ~F and cooling is at about 35 ~F.
L'invention concerne un procédé et un dispositif destinés à former des produits thermoplastiques comprenant des surfaces gaufrées précises. Ce procédé consiste à utiliser une presse continue (40) comprenant des bandes supérieure et inférieure (50, 52) pourvues de modèles de gaufrage, à faire passer ces matières thermoplastiques à travers cette presse (40), à appliquer de la chaleur et une pression sur lesdites matières, à les faire refroidir ensuite tout en maintenant la pression dans une zone de réaction (53). Cette pression est maintenue à 250 psi environ, le chauffage s'effectue à 480 ·F environ et le refroidissement à 35 ·F environ.
