Description

Vorrichtung zum Herstellen eines Rinnenprofils, insbesondere Regenrinnenprofils, aus thermoplastischem Werkstoff Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen eines Rinnenprofils, insbesondere Regenrinnenprofils, aus thermoplastischem Werkstoff durch Extrudieren eines Rohres und Aufschlitzen des noch warmen Rohres durch der Extruderdüse nachgeschaltete Schlitz- und Ziehwerkzeuge.Device for producing a gutter profile, in particular a gutter profile, made of thermoplastic material The invention relates to a device for producing a gutter profile, in particular a gutter profile, made of thermoplastic Material by extruding a pipe and slitting the still warm pipe slitting and drawing tools connected downstream of the extruder nozzle.

Wegen der Korrosionsanfälligkeit von Zink stellt man Regenrinnen und Regenfallrohre gern aus säurebeständigem, thermoplastischem Kunststoff, beispielsweise aus Polyvinylchlorid und dessen Mischpolymerisaten, her. Because zinc is susceptible to corrosion, rain gutters are installed and downpipes made of acid-resistant, thermoplastic material, for example made of polyvinyl chloride and its copolymers.

Das Regenrinnenprofil wird dabei aus flachen Kunststoffolien durch Warmverformung gewonnen, beispielsweise in der Weise, daß das Material bandförmig extrudiert und anschließend im noch warmen Zustand mittels eines Ziehwerkzeugs in die gewünschte Form gebracht wird. Die Regenfallrohre können unmittelbar extrudiert, gegebenenfalls danach noch durch ein Ziehwerkzeug kalibriert werden. The gutter profile is made of flat plastic sheeting Hot deformation obtained, for example in such a way that the material is band-shaped extruded and then while still warm using a drawing tool in the desired shape is brought. The downpipes can be extruded directly, if necessary, then calibrated using a drawing tool.

Bei Anwendung dieser bekannten Herstellungsweise sind für die Herstellung von Regelfallrohren einerseits und von Regenrinnen andererseits verschieden geformte Extruderdüsen notwendig. When using this known production method are for the production differently shaped by regular downpipes on the one hand and by rain gutters on the other Extruder nozzles necessary.

Es ist auch bekannt, daß Folien, Filme und offene Profile in der Weise erzeugt werden können, daß eine Extruderdüse, aus der das Material rohrförmig austritt, mit einem Messer zum Aufschlitzen dieses Rohres versehen ist und dieser Vorrichtung ein Verformungswerkzeug nachgeschaltet ist. It is also known that foils, films and open profiles in the Way can be produced that an extruder nozzle, from which the material is tubular emerges, is provided with a knife for slitting this pipe and this Device is followed by a deformation tool.

Der Erfindung liegt die Aufgabe zugrunde, den Aufwand an Vorrichtungen für den besonderen Fall zu vermindern, daß unter Benutzung einer und derselben Extrudermaschine wahlweise Regenrinnen und Regenfallrohre erzeugt werden sollen; weiterhin soll der für eine Umstellung der Maschine notwendige Arbeits- und Zeitaufwand verringert werden. The invention is based on the problem of the expenditure on devices for the special case that using one and the same extruder machine optionally rain gutters and downpipes are to be created; continue to Reduced the amount of work and time required to move the machine will.

Diese Aufgabe wird bei der eingangs genannten Vorrichtung erfindungsgemäß dadurch gelöst, daß die Schlitz- und Ziehwerkzeuge zu einer wahlweise vor die Strangpresse zu setzenden selbständigen Ein- heit zusammengefaßt sind. Dadurch wird es möglich, mittels einer Extrudermaschine, deren Düse auf die Herstellung von Regenabfallrohren eingestellt ist, ohne Austausch der Düse oder Verstellung der Maschine durch einfaches Vorsetzen des Schlitz- und Ziehwerkzeugs Regenrinnen herzustellen. Die Kühltechnik wird den Erfordernissen in bekannter Weise angepaßt. This object is achieved according to the invention in the device mentioned at the beginning solved in that the slotting and drawing tools to an optional before the extrusion press to be set independent are summarized. This makes it possible by means of an extruder machine, the nozzle of which is used for the production of rain waste pipes is set, without changing the nozzle or adjusting the machine by simply Positioning the slitting and pulling tool to produce gutters. The cooling technology is adapted to the requirements in a known manner.
