Aus
der Druckschrift
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine Extrudervorrichtung bereitzustellen, die eine konstruktiv einfache Schneidgeometrie aufweist. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Neben- und Unteransprüchen.Of the The invention is in particular the object of an extruder device to provide, which has a structurally simple cutting geometry. It is according to the invention solved by the features of claim 1. Further embodiments result from the secondary and dependent claims.
Vorteile der ErfindungAdvantages of invention
Die Erfindung geht aus von einer Extrudervorrichtung mit zumindest zwei Extrudergehäuseteilabschnitten, die hintereinander angeordnet sind und mit einem Übergang.The The invention is based on an extruder device with at least two Extruder barrel sections, which are arranged one behind the other and with a transition.
Es wird vorgeschlagen, dass der Übergang einen Konturwechsel aufweist. Dadurch können Teilbereiche der Extrudervorrichtung vorteilhaft auf ihre Funktion ausgelegt werden. Der Übergang ist bevorzugt zwischen den beiden Extrudergehäuseteilabschnitten angeordnet.It It is suggested that the transition one Contour change has. As a result, portions of the extruder device be advantageously designed for their function. The transition is preferably arranged between the two extruder housing sections.
Des Weiteren wird vorgeschlagen, dass der Übergang gestuft oder konisch ausgeführt ist. Ist dieser Übergang an einem Extrudergehäuseteilabschnitt angeordnet, der einen Spalt zwischen dem Extrudergehäuse und einem darin angeordneten Förderelement bildet, kann ein schonender Übertrag zwischen zwei Extrudergehäuseteilabschnitten erreicht werden. Ferner kann ein Faserstrang, der entweder eine Kurzglasfaser, einen Roving bzw. einen Endlosfaserstrang und/oder einen anderen, dem Fachmann als sinnvoll erscheinenden Faserstrang darstellt, den Übergang beschädigungsfrei passieren.Of It is also suggested that the transition be stepped or conical accomplished is. Is this transition on an extruder housing section arranged, which has a gap between the extruder housing and a conveying element arranged therein forms a gentle carry between two extruder housing sections be achieved. Furthermore, a fiber strand, either a Short glass fiber, a roving or an endless fiber strand and / or represents another fiber strand that appears appropriate to a person skilled in the art, the transition without damage happen.
Vorteilhafterweise ist ein Führungsfreiraum vorgesehen, der einen Faserstrang beschädigungsfrei führt. Durch die Anordnung dieses Bereichs kann eine definierte und schonende Führung des Faserstrangs konstruktiv einfach erzielt werden.advantageously, is a guidance free space provided the one fiber strand damage leads. The arrangement of this area can be a defined and gentle guide the fiber strand can be achieved structurally simple.
Ferner ist es vorteilhaft, wenn eine Zerteilungseinheit vorgesehen ist, die einen Faserstrang in einer Austrag- und Förderstrecke zerteilt. Dadurch kann erreicht werden, dass die Faserstränge vor einem Verlassen der Extrudervorrichtung konstruktiv einfach unterteilt werden.Further it is advantageous if a dividing unit is provided, which divides a fiber strand in a discharge and conveying section. This can be achieved that the fiber strands before leaving the Extruder device structurally simple to be divided.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Zerteilungseinheit von einem Förderelement gebildet ist. Diese Ausgestaltung ist konstruktiv einfach und dadurch kann die Ausgestaltung einer speziell für einen Unterteilprozess geformten Geometrie, beispielsweise in der Form einer scharfen Schneidkante, die an einer Innenwand des Extrudergehäuses angeordnet ist, Kosten sparend vermieden werden.In Another embodiment of the invention proposes that the dividing unit is formed by a conveying element. These Design is structurally simple and thereby the design a specially for a base process molded geometry, for example in the form a sharp cutting edge, which is arranged on an inner wall of the extruder housing is to be avoided cost-saving.
Des Weiteren geht die Erfindung von einem Verfahren zum Betreiben einer Extrudervorrichtung aus.Of Furthermore, the invention of a method for operating a Extruder device off.
Es wird vorgeschlagen, dass der Übergang durch einen Konturwechsel gebildet wird. Dadurch können Teilbereiche der Extrudervorrichtung vorteilhaft auf ihre Funktion ausgelegt werden.It It is suggested that the transition through a contour change is formed. As a result, portions of the extruder device be advantageously designed for their function.
Des Weiteren kann es vorteilhaft sein, wenn ein Faserstrang bei einem Transport über den Übergang beschädigungsfrei geführt wird.Of Furthermore, it may be advantageous if a fiber strand at a Transport over the transition without damage guided becomes.
