Abstract

Abstract Translated from German Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von thermoplastischen Bahnen aus mindestens einer extrudierten, auf Verarbeitungstemperatür erwärmten Thermoplastbahn. Diese Thermoplastbahn wird unter Einwirkung von Flächendruck bis zu der Temperatur abgekühlt, bei der das Glätten der Oberfläche beendet ist. Die Kalibrier- und Glätteinrichtung bei der Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens besteht aus einer Doppelbandpresse, die in der Reaktionszone, in der der Flächendruck aufgebracht wird, eine Einrichtung zum Abführen der Wärme von der Thermoplastbahn besitzt. The invention relates to a process for the continuous production of thermoplastic webs from at least one extruded thermoplastic web heated to processing temperature. This thermoplastic web is cooled under the action of surface pressure up to the temperature at which the smoothing of the surface has ended. The calibration and smoothing device in the device for carrying out the method according to the invention consists of a double belt press which, in the reaction zone in which the surface pressure is applied, has a device for dissipating the heat from the thermoplastic web.
