Title (EN) SEAL DEVICE FOR A NEGATIVE PRESSURE CALIBRATING UNIT IN AN EXTRUSION LINE
(FR) DISPOSITIF D'ÉTANCHÉITÉ POUR UNE UNITÉ DE CALIBRAGE SOUS VIDE DANS UNE LIGNE D'EXTRUSION
(DE) DICHTUNGSVORRICHTUNG FÜR EINE UNTERDRUCK-KALIBRIEREINHEIT IN EINER EXTRUSIONSLINIE
Abstract:
(EN) The invention relates to a seal device for a negative pressure calibrating unit in an extrusion line for producing profiled plastic sections, in particular pipes. The inner face of a seal rests against the circumference of the extruded profiled section in a formfitting manner, and the seal is radially supported on the profiled section in order to apply a sealing force. The aim of the invention is to provide another similar device which is very easily constructed and can be produced inexpensively. This is achieved in that the seal is a porous and elastic foam body (13), the surfaces (17, 19) of which that are exposed to the atmosphere are coated with an air-tight coating (21).
(FR) La présente invention concerne un dispositif d'étanchéité pour une unité de calibrage sous vide dans une ligne d'extrusion servant à produire des profilés en matière plastique, notamment des tubes, une surface intérieure d'un élément d'étanchéité prenant appui par complémentarité de forme sur la périphérie du profilé extrudé et étant en appui radialement pour appliquer une force d'étanchéité sur le profilé. L'invention vise à mettre au point un autre dispositif de ce type, de conception très simple et pouvant être fabriqué de manière économique. A cet effet, l'élément d'étanchéité est un corps en mousse (13) poreux et élastique, dont les surfaces (17, 19) exposées à l'atmosphère sont pourvues d'un revêtement (21) étanche à l'air.
(DE) Die vorliegende Erfindung betrifft eine Dichtungsvorrichtung für eine Unterdruck-Kalibriereinheit in einer Extrusionslinie zur Herstellung von Kunststoffprofilen, insbesondere von Rohren, wobei eine Dichtung mit einer Innenfläche formschlüssig am Umfang des extrudierten Profils anliegt und zum Aufbringen einer Dichtkraft auf das Profil radial abgestützt ist. Aufgabe der Erfindung ist es eine weitere derartige Vorrichtung zur Verfügung zu stellen, die sehr einfach aufgebaut und kostengünstig herstellbar ist. Gelöst wird diese Aufgabe dadurch, dass die Dichtung ein poröser und elastischer Schaumkörper (13) ist, dessen der Atmosphäre ausgesetzten Flächen (17, 19) mit einer luftdichten Beschichtung (21) versehen sind.
