Method and apparatus for the continuous production of thermoplastic sheets
Abstract
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.
