Abstract

Bei einem Verfahren zum Herstellen von Endmuffen (2) an Kunststoffrohren (1) aus in warmem Zustand formbaren Kunststoffen, insbesondere Polyolefinen wie Polyethylen und Polypropylen, wird ein etwa die Muffenlänge aufweisender Bereich am Ende des Rohres (1) in einer Heizstation auf bzw. über seine Verformungstemperatur erwärmt, in diesem Zustand in einer Aufmuffstation auf einen über dem gewünschten Innendurchmesser liegenden Durchmesser aufgemufft, vor und/oder nach dem Ziehen des Aufmuffwerkzeuges in einer Kühlstation unter die Warmverformungstemperatur abgekühlt und in abgekühltem Zustand in einer Endformstation kurzfristig mittels eines Preßwerkzeuges auf ein Untermaß zusammengedrückt. Zur Erzielung einer hohen Maßgenauigkeit bei der Serien- und Einzelfertigung wird der Innendurchmesser der Muffe (2) wenigstens nach dem Ziehen des Aufmuffwerkzeuges, während der Verweildauer im Preßwerkzeug und nach dem Austritt aus dem Preßwerkzeug berührungslos mittels eines Lastertasters (19, 20) gemessen. Die Meßwerte werden in digitaler Form gespeichert, unter Verwendung eines Rechners mit vorgebbaren Sollwerten verglichen und für die Erzeugung von Steuersignalen zur Feinregelung der in der Heizstation zugeführten bzw. in der Kühlstation abgeleiteten Wärmemenge sowie zur Bestimmung der Verweildauer im Preßwerkzeug verwendet. Ein Meßgerät zur Durchführung des Verfahrens ist angegeben.
