Abstract

The appts. has a spiral guide rail, arranged in a heatable casing, for the haul-off of the rubber profile. The guide rail may have a U- or L-shaped cross-section. Enables non-straight profiles to be produced (e.g. rubber gaskets to be fitted round windscreen edges ("weather strips") which have no undesirable wrinkling at the inner surface of a curve. The guide rail may be fitted with a roller for easy conveyance of the extrudate. Vibrators may also be provided, for the same purpose. The device may feature >1 spiral guide rail, for simultaneous vulcanisation of several rubber profiles.

Description

Vorrichtung zum Vulkanisieren von einem aus einem Extruder ausgestoßenen GummiprofilstrangDevice for vulcanizing a rubber profile strand ejected from an extruder

Die Erfindung bezieht sich auf eine Vorrichtung zum Vulkanisieren eines aus einem Extruder ausgestoßenen Gummiprofilstranges. The invention relates to a device for vulcanizing a rubber profile strand ejected from an extruder.

Diese Profilstränge werden gewöhnlich in einem beheizten
Gehäuse gestreckt, also gerade gerichtet, vulkanisiert.These profile strands are usually in a heated
Housing stretched, i.e. straightened, vulcanized.

Hierdurch sind die Anwendungsgebiete dieser gestreckt vulkanisierten Gummiprofilstränge sehr begrenzt, da es, beispielsweise bei Dichtungen vielfach nötig ist, den Gummiprofilstrang um Ecken oder um runde Gegenstände, wie abgerundete Automobilfenster zu führen. Wenn hierzu gestreckt vulkanisierte Gummiprofilstränge verwendet werden, so ent-As a result, the areas of application of this stretch vulcanized Rubber profile strands are very limited, since it is often necessary, for example in the case of seals, to use the rubber profile strand around corners or around round objects such as rounded automobile windows. If this is stretched vulcanized rubber profile strands are used, so

stehen am inneren Rand der Profile Falten, welche die Verwendung dieser gerade gestreckten Profile für die genannten Zwecke ausschließen.stand on the inner edge of the profile folds, which the use of these straight stretched profiles for the said Exclude purposes.

Man hat daher schon versucht, rundgeformte Guinmiprofilstränge dadurch zu erhalten, daß diese von dem Extruder ausgestoßenen Stränge in eine rotierende, kreisförmige Pfanne hineingespritzt wurden.Attempts have therefore already been made to make round guinmi profile strands obtained by injecting these strands ejected from the extruder into a rotating, circular pan became.

Die Gummiprofilstränge rollten sich dann an dem inneren Rand der Pfanne spiralig auf und erhielten so eine runde Form.The rubber profile strands then curled on the inner edge the pan in a spiral, giving it a round shape.

Hierauf mußte, wenn die Pfanne gefüllt war, diese in einen beheizten Behälter eingebracht werden, wo die Vulkanisierung erfolgte.Then, when the pan was full, it had to be placed in a heated container where the vulcanization took place took place.

Nach diesem Vorgang mußten die Gummiprofilstränge gewaschen und dann in die Fertigmacherei gebracht werden.After this process, the rubber profile strands had to be washed and then taken to the finishing shop.

Diese Fertigungsmethode war sehr aufwendig, lohnintensiv und erforderte einen erheblichen Raumbedarf.This production method was very complex, labor intensive and required a considerable amount of space.

Aufgabe der Vorrichtung gemäß der Erfindung zum Vulkanisieren von einem aus einem Extruder ausgestoßenen Gummiprofilstrang ist es, einen Gummiprofilstrang zu erhalten, der abgerundet vulkanisiert wird und somit bei seiner Verwendung keine Falten aufweist und die in ihrer Anwendung wenig aufwendig ist.Object of the device according to the invention for vulcanizing from a strand of rubber profiles ejected from an extruder is to obtain a rubber profile that is vulcanized in a rounded shape and thus no wrinkles when it is used and which is not very expensive to use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Ableitung des Gummiprofiistranges eine in einem beheizbaren Gehäuse angeordnete spiralig geformte Führungsschiene vorgesehen ist.This object is achieved in that for Derivation of the rubber profile strand is provided in a spirally shaped guide rail arranged in a heatable housing is.

Um den Gummiprofilstrang sicher zu führen, besitzt die Führungsschiene U-förmigen oder L-förmigen Querschnitt.In order to safely guide the rubber profile strand, the Guide rail U-shaped or L-shaped cross-section.

Ferner ist es möglich, zum Transport des Gummiprofilstranges, in den Führungsschienen Röllchen vorzusehen, die gegebenenfalls angetrieben werden.It is also possible to transport the rubber profile strand, to provide rollers in the guide rails, which may be driven.

Auch können zur Förderung des Gummiprofilstranges Vibratoren z.B. mittels Ultra-Schall auf die Führungsschienen einwirken.Vibrators can also be used to promote the rubber profile strand e.g. act on the guide rails by means of ultra-sound.

Schließlich kann die Vorrichtung dadurch besonders wirtschaftlich geschaffen werden, daß in dem gleichen Gehäuse mehrere spiralig geformte Führungsschienen zur gleichzeitigen Vulkanisation mehrerer Gummiprofilstränge vorgesehen sind. Diese Führungsschienen können parallel oder auch gegenläufig angeordnet sein.Finally, the device can be created particularly economically that in the same housing several spirally shaped guide rails are provided for the simultaneous vulcanization of several rubber profile strands. These guide rails can be arranged in parallel or in opposite directions.

Durch die Erfindung gelingt es auf einfache Weise, Gummiprofilstränge zu erhalten, die nach der Vulkanisation rund geformt sind und vielerlei Einsatzmöglichkeiten gestatten.The invention makes it possible in a simple manner to produce rubber profile strands that are round after vulcanization and allow a wide range of uses.

Besondere Vorteile der Vorrichtung gemäß der Erfindung liegen vor allem darin, daß die Fertigung der Gummiprofilstränge vom Extruder aus bis am Verpacken kontinuierlich erfolgt und einen sehr geringen Raumbedarf beansprucht.Particular advantages of the device according to the invention are primarily that the production of the rubber profile strands takes place continuously from the extruder to the packaging and takes up very little space.

In der Zeichnung sind Ausführungsbeispiele einer Vorrichtung gemäß der Erfindung schematisch dargestellt.In the drawing, exemplary embodiments of a device according to the invention are shown schematically.
