The tongue has an extension passing through a hollow extruded profile. The end of the tongue lies behind a softening (plastifying) zone. A trailing mandrel having the same profile as the tongue is arranged at the end of the tongue. At least 1 coating roller and at least 1 supporting roller are arranged in the region of the mandrel. Used to apply a covering foil e.g. to plastics door or window frames. Pressure may be applied during laminating without risk of deforming the plastics profile.

Description

Beschichtungs-Vorrichtung Die Erfindung betrifft eine Vorrichtung zum Beschichten einer im plastischen Zustand befindlichen Oberfläche eines aus Kunststoff bestehenden Profils mit einer Folie. Coating device The invention relates to a device for coating a surface in the plastic state made of plastic existing profile with a foil.

Profile dieser Art werden für die verschiedensten Zwecke, beispielsweise für bewegliche Wände, Tür- und Fensterrahmen, Balkonverkleidungen und dergleichen verwendet, deren Oberfläche aus technischen oder auch geschmacklichen Gründen dem jeweiligen Verwendungszweck angepaßt werden soll.Profiles of this type are used for a wide variety of purposes, for example for movable walls, door and window frames, balcony cladding and the like used whose surface for technical or taste reasons dem to be adapted to the respective purpose.

Während bei der Beschichtung massiver Profile die aus beliebigen Werkstoffen bestehenden Folien noch vor dem Erstarren bzw. Erkalten des aus dem Extruder austretenden Profils auf dieses aufgebracht werden und hierbei eine innige, mechanischen und thermischen Beanspruchungen standhaltende Verbindung erzielt wird, muß man sich bei der Beschichtung von Hohlprofilen damit begnügen, die Folien auf die bereits erstarrten Profile aufzukleben, da beim Aufbringen der Folie auf die noch plastischen Hohlprofile infolge des notwendigerweise aufzuwendenden Druckes die Gefahr einer Formveränderung des Hohlprofils besteht.Whereas when coating massive profiles, those made of any material existing foils before the solidification or cooling of the one emerging from the extruder Profile are applied to this and this is an intimate, mechanical and thermal stress-resistant connection is achieved, you have to When coating hollow profiles, content with the foils on the already Glue on solidified profiles, as when the film is applied to the still plastic ones Hollow profiles as a result of the necessary pressure to be used, the risk of a There is a change in shape of the hollow profile.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Beschichtungsvorrichtung zu schaffen, mittels der auf eine in plastischem Zustand befindliche Oberfläche eines Hohlprofils eine Folie unter Druck aufgebracht werden kann, ohne daß die Gefahr einer Formveränderung des Profils besteht.The invention is therefore based on the object of a coating device to create, by means of the on a surface in a plastic state of a hollow profile, a film can be applied under pressure without the risk there is a change in shape of the profile.

Diese Aufgabe wird bei einem bereits erstarrten Hohlprofil gemäß der Erfindung dadurch gelöst, daß die im Formkanal eines Extrudergehäuses angeordnete Zunge eine das extrudierte Hohlprofil durchsetzende Verlängerung aufweist, an deren hinter einer Erweichungszone liegendem Ende ein dasselbe Profil wie die Zunge aufweisender Schleppdorn angeordnet ist, in dessen Bereich mindestens eine Beschichtungswalze und mindestens eine Unterstützungswalze angeordnet ist. Diese Verlängerung weist zur Vermeidung von Gleitreibungswiderständen ein kleineres Profil als die Zunge des Formkanals auf und besteht vorteilhafterweise aus einem an seinen beiden Enden ein Gewinde aufweisenden Rundstab, der mit seinem einen Ende in ein Innengewinde der Formkanalzunge und mit seinem anderen Ende in ein Innengewinde des Schleppdorns eingeschraubt ist.This task is with an already solidified hollow profile according to Invention achieved in that the arranged in the molding channel of an extruder housing Tongue has an extension penetrating the extruded hollow profile, on the behind a softening zone same profile how the tongue-having drag mandrel is arranged, in its area at least a coating roller and at least one support roller is arranged. This extension has a smaller one to avoid sliding friction resistance Profile as the tongue of the molding channel and advantageously consists of one at its two ends a round rod having a thread, which with its one end into an internal thread of the molding channel tongue and at its other end into an internal thread of the drag mandrel is screwed in.

Das aus dem Extruder austretende Hohlprofil durchläuft vorteilhafterweise eine Kalibriereinrichtung und anschließend an diese eine Zone, in der die zu beschichtende Oberfläche des Hohlprofils mittels einer oder mehrerer Heißluftdüsen erweicht wird. Hinter der Erweichungszone wird das Hohlprofil über den Schleppdorn gezogen, wobei auf die Oberfläche des vorteilhafterweiserri#einer oder mehrerer Walzen unterstützten Hohlprofils mittels einer Beschichtungswalze eine von einer Vorratswalze abgezogene Folie aufgebracht wird.The hollow profile emerging from the extruder advantageously passes through a calibration device and then a zone in which the Surface of the hollow profile is softened by means of one or more hot air nozzles. Behind the softening zone, the hollow profile is pulled over the drag mandrel, with supported on the surface of the advantageously one or more rollers Hollow profile drawn off from a supply roller by means of a coating roller Foil is applied.

Soll das Hohlprofil beidseitig mit einer Folie beschichtet werden, so ist auf der der Beschichtungswalze gegenüberliegenden Oberfläche des Hohlprofils anstelle einer Unterstützungswalze oder auch zusätzlich zu einer oder mehreren Unterstützungswalzen eine weitere Beschichtungswalze angeordnet, der in gleicher Weise eine gegebenenfalls unterschiedliche Folie zugeleitet wird.If the hollow profile is to be coated on both sides with a film, so is on the surface of the hollow profile opposite the coating roller instead of a support roller or in addition to one or a plurality of support rollers, a further coating roller is arranged, the an optionally different film is fed in the same way.

Werden, vorteilhafterweise gegenüber zwei solchen Beschichtungswalzen in Längsrichtung des abgezogenen Hohlprofils versetzt, zwei weitere Beschichtungswalzen senkrecht zu den beiden vorgenannten Beschichtungswalzen angeordnet, so kann das Hohlprofil rundum mit einer Folie kaschiert werden.Will be advantageous over two such coating rolls offset in the longitudinal direction of the withdrawn hollow profile, two further coating rollers arranged perpendicular to the two aforementioned coating rollers, so that can Hollow profile are covered all around with a film.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung in schematischer Weise dargestellt.In the drawing is an embodiment of the invention Device shown in a schematic manner.

Das Hohlprofil 1 wird mittels in der Zeichnung nicht dargestellter Reibwalzen aus der Vorrichtung abgezogen, die ein Extrudergehäuse 2 aufweist, in deren Formkanal eine Zunge 3 angeordnet ist. In geringem Abstand von dem Extruder ist eine Kalibriereinrichtung 4 und im Abstand von dieser ein Heißluftgebläse 5 angeordnet, mittels dessen über eine Mehrzahl von Düsen Heißluft auf die zu beschichtende Oberfläche des Hohlprofils geblasen wird, so daß dieses mindestens an seiner zu beschichtenden Oberfläche erweicht. Hierauf wird das Hohlprofil über einen mit der Zunge 3 fluchtenden, dasselbe Profil aufweisenden Dorn 6 gezogen, der mittels eines das Hohlprofil durchsetzenden Rundstabes 11 mit der Zunge 3 verbunden ist und somit stets im gleichen Abstand von dieser gehalten wird. Im Bereich des Schleppdorns 6 liegt das Hohlprofil auf zwei Unterstützungswalzen 7 und 7' auf, die über den Schleppdorn 6 ein Widerlager für die Beschichtungswalze 8 bilden, der die Folie 9 über-eine Spannwalze 10 zugeführt wird.The hollow profile 1 is not shown in the drawing by means of Friction rollers withdrawn from the device, which has an extruder housing 2, in the molding channel of which a tongue 3 is arranged. At a short distance from the extruder is a calibration device 4 and a hot air blower 5 at a distance from it arranged, by means of which hot air to the to be coated via a plurality of nozzles Surface of the hollow profile is blown, so that this at least at its to coating surface softens. Then the hollow profile is over a with the tongue 3 aligned, drawn the same profile having mandrel 6, which means a round rod 11 penetrating the hollow profile is connected to the tongue 3 and is therefore always kept at the same distance from it. In the area of the tow mandrel 6 is the hollow profile on two support rollers 7 and 7 ', which over the Drag mandrel 6 form an abutment for the coating roller 8, which holds the film 9 is fed via a tension roller 10.
