Description
Verfahren zum Herstellen von verstärkten offenen Profilen aus Kunststoff Die Erfindung bezieht sich auf die Herstellung von, vorzugsweise durch Glasfasern, verstärkten, offenen Profilen aus Kunststoff durch Aufwickeln von Fasersträngen auf einen Dorn, Imprägnieren der Fasern mit dem Kunststoff und Zertrennen der gewickelten Rohre längs zweier oder mehrerer Trennlinien zu offenen Profilen.Process for the production of reinforced open profiles from plastic The invention relates to the production of, preferably by glass fibers, Reinforced, open profiles made of plastic by winding up fiber strands onto a mandrel, impregnating the fibers with the plastic and severing the wound ones Pipes along two or more dividing lines to open profiles.
Es ist bereits bekannt, Formkörper durch Aufwickeln von Glasfaserbändern auf einen Dorn oder eine Form herzustellen und diese gewickelten Erzeugnisse mit Kunststoff zu imprägnieren und sie dann nach einer unter Umständen vorher noch erfolgenden Verformung längs zweier oder mehrerer Trennlinien zu offenen Profilen zu verarbeiten. Hierbei erfolgte bei den bekannten Einrichtungen das Trennen der Profile durch scharfe Messer oder ähnliche Schneideinrichtungen, die jedoch, durch die Härte der Glasfasern bedingt, einem schnellen Verschleiß unterliegen. Hierdurch war entweder ein ständiges Auswechseln der Messer oder Schneideinrichtung erforderlich, oder diese Schneideinrichtungen mußten aus einem solchen kostspieligen Werkstoff angefertigt werden, daß hierdurch das Herstellungsverfahren der Profile erheblich verteuert wurde. Auch trat es immer wieder ein, daß einzelne Glasfasern nicht vollständig zerschnitten wurden und so eine Nachbearbeitung erforderlich war oder ein Verletzen und Einreißen der gesamten Profile eintrat. It is already known to produce molded bodies by winding up glass fiber tapes on a mandrel or a mold and these wound products with To impregnate plastic and then after a possibly previously done Process deformation along two or more dividing lines into open profiles. In the known devices, the profiles were separated by sharp ones Knives or similar cutting devices, however, due to the hardness of the glass fibers conditionally, subject to rapid wear. This made either a permanent Replacement of the knife or cutting device required, or these cutting devices had to be made of such a costly material that as a result the manufacturing process of the profiles has become considerably more expensive. It also always kicked again that individual glass fibers were not completely cut and so on reworking was required or injuring and tearing the whole Profile entered.
Diese Nachteile der bekannten Verfahren werden gemäß der Erfindung dadurch vermieden, daß vor dem Aufwickeln der Faserstränge auf den Dorn auf diesen im Bereich der beabsichtigten Trenalinien Reißdrähte verlegt werden, die gemäß einer bevorzugten Ausführungsform der Erfindung durch Hindurchleiten von Strom erhitzt werden können. Hierdurch ist ein schnelles und einwandfreies Durchtrennen der einzelnen Profilsegmente möglich, ohne daß Verletzungen der Profilkanten befürchtet werden müssen. Durch die entsprechende Wahl des Drahtwerkstoffes können die einzelnen Drähte auf eine der jeweiligen Kunststoffart angepaßte Höhe erhitzt werden, so daß also ein Durchschweißen der Profilwandung eintritt. These disadvantages of the known methods are addressed according to the invention thereby avoided that before winding the fiber strands onto the mandrel on this tear wires are laid in the area of the intended trenal lines, which according to a preferred embodiment of the invention heated by passing current can be. This enables the individual to be severed quickly and properly Profile segments possible without fear of damaging the profile edges have to. The individual wires be heated to a height adapted to the respective type of plastic, so that welding through of the profile wall occurs.
In der Zeichnung ist eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens schematisch dargestellt. Mit a ist in der Zeichnung der Wickeldorn bezeichnet, der zwei Längskerbenb, b' aufweist, in die die Reißdrähte c, c' eingelegt sind. In the drawing is a device for carrying out the invention Procedure shown schematically. In the drawing, the winding mandrel is denoted by a, which has two longitudinal notches b, b 'into which the tear wires c, c' are inserted.
Um diesen Wickeldorn mit den eingelegten Drähten c, c' wird nunmehr der Wickelkörper d gewickelt.This winding mandrel with the inserted wires c, c 'is now the bobbin d wound.
Nach dem Imprägnieren und gegebenenfalls Aushärten des Wickelkörpers wird er durch Abziehen der Drähte c, c' in Richtung der beiden Pfeile f in zwei offene Profile zertrennt.After the winding body has been impregnated and, if necessary, hardened it is made by pulling off the wires c, c 'in the direction of the two arrows f in two cut open profiles.
Die Erfindung ist nicht auf das vorstehend beschriebehe und in der Zeichnung dargestellte Ausführungsbeispiel beschränkt. So können beispielsweise beliebige andere Profilformen hergestellt werden oder die Trennlinie zwischen den Profilen keilförmig ausgebildet sein oder auch eine durchgebogene Form aufweisen. The invention is not limited to the above and in the Embodiment shown in the drawing is limited. For example any other profile shapes can be produced or the dividing line between the Profiles be wedge-shaped or have a curved shape.
