ABSTRACT:
A process for continuous fabrication of thermoplastic webs from at least one extruded thermoplastic web heated to processing temperature. This thermoplastic web is cooled under the application of area pressure down to a temperature at which smoothing of the surface is terminated. A calibrating and smoothing mechanism in the device for performing the process according to the invention consists of a double-band press which includes an apparatus for conducting heat away from the thermoplastic web in the reaction zone in which the area pressure is applied.
