Description

Verfahren zum Herstellen von Stangen, Leisten und ähnlichen langgestreckten, beliebig langen Gegenständen aus härtbarem Kunstharz nach dem Strangpreßverfahren Beim Herstellen von Stangen, Leisten und anderen langen Gegenständen aus härtbarem Kunstharz nach dem Strangpreßverfahren wird durch den Stempeldruclç die eine Stirnseite jedes Preßlingsabschnittes geglättet.Process for the production of bars, strips and similar elongated, Objects of any length made of curable synthetic resin after the extrusion process When making bars, strips and other long objects from hardenable materials Synthetic resin after the extrusion process is one end face through the stamp pressure smoothed each compact section.

Diese glatte Stirnfläche des Preßlingsabschnittes muß sich mit dem nächstgebildeten Preßlingsabschuitt vereinigen zur Bildung g des Formkörpers.This smooth face of the pressed part must be with the next formed Preßlingsabschuitt combine to form g of the molded body.

Hierbei können sich Übelstände ergeben, die darauf zurückzuführen sind, daß die Verbindutig der einzelnen Preßlingsabschnitte an diese glatten Sti.rnfläclien ungleichartig erfolgt, so daß der Formling an diesen Stellen geringere Festigkeitseigenschaften hat und also insgesamt ein Formling mit nicht gleichmäßigen Festigkeitseigenschaften über seine ganze Länge entsteht. This can lead to evils that can be traced back to it are that the connection of the individual pressed parts to these smooth pin surfaces takes place unevenly, so that the molding has lower strength properties at these points and therefore overall a molding with non-uniform strength properties arises over its entire length.

Es ist schon aus anderen Gründen vorgeschlagen worden, bei dem Strangpreßverfahren, ausgehend von härtbaren Kun.stharzen, den Übergang von dem Raum, in dem der Stempel wirkt, zum Formraum z. B. kegelig zu gestalten, wobei die Verbin,dung der einzelnen Preßlingsabschnitte ebenfalls nicht an der glatten Stirnfläche ein.tntt. It has already been proposed for other reasons, in the extrusion process, starting from curable synthetic resins, the transition from the space in which the stamp acts to the mold space z. B. to be conical, with the connec tion of the individual Sections of the pressed part also do not penetrate the smooth face.

Gemäß der Erfindung werden diese glatten, durch den Stempeldruck erzeugten Stirnflächen vor dem endgültigen Vereinigen der Preßlingsabschnitte zerrissen. According to the invention, these are smooth, due to the stamp pressure generated end faces torn before the final unification of the compact sections.

Dies geschieht z. B. dadurch, daß ein die Stirnfläche zerteilender Dorn oder Keil angebracht wird, durch den die glatten Stirnflächen zerstört werden. This happens e.g. B. in that a dividing the end face Thorn or wedge is attached, by which the smooth end faces are destroyed.

Die gemäß der Erfindung hergestellten langgestreckten Körper haben an den Verbindungsstellen nicht mehr eine geringere Festigkeit, sondern der Formling hat in allen Teilen gleichmäßige Festigkeitseigenschaften. The elongated bodies made according to the invention have at the connection points no longer a lower strength, but the molding has uniform strength properties in all parts.

PATENTANSPRUCH: Verfahren zum Herstellen von Stangen, Leisten und ähnlichen langgestreckten, beliebig langen Gegenständen aus härtbarem Kunstharz nach dem Strangpreßverfahren, dadurch gekennzeichnet, daß die durch den Stempeldruck zunächst erzeugten glatten Stirnflächen der Preßlingsabschnitte im weiteren Verlauf des Preßverfahrens zerrissen werden, z. B. durch im Formkanal angebrachte Dorne oder Keile, so daß das Vereinigen der einzelnen Preßlingsabschnitte nicht an die glatten, durch den Stempeldruck erzeugten Stirnflächen erfolgt. PATENT CLAIM: Process for the production of bars, strips and similar elongated objects of any length made of curable synthetic resin according to the extrusion process, characterized in that the die pressure initially produced smooth end faces of the pressed part sections in the further course of the pressing process are torn, e.g. B. by attached mandrels in the mold channel or wedges, so that the unification of the individual compact sections does not affect the smooth end faces generated by the stamp pressure.
