1. Verfahren zur Herstellung eines langgestreckten Gegenstandes
von vorher ausgewählter Querschnittsgestaltung aus einem thermoplastischen
Material durch Pressen dieees Materials durch einen Durchgang mit einem Abgabeendteil, der diese Querschnittsgestaltung
bestimmt, dadurch gekennzeichnet,daß eine Kraft gegen die
äußere Oberfläche dieses Materials während seines Weges bzw. Gleitens durch diesen Durchgang aufrechterhalten wird.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß ebenso eine Kraft nach außen gegen die innere Oberfläche dieses Materials
in diesem Durchgang aufrechterhalten wird.
3. Strangpressform zum Strangpressen eines Kunststoff materials,
wobei diese Form einen Dorn enthält, der von einer Buchse umgeben und in einem Abstand von dieser angeordnet ist, um einen ringförmigen
Strangpressdurchgang auszubilden, dadurch gekennzeichnet, daß diese Buchse eine innere Wand aufweist, die konisch bzw. spitz
zuläuft, damit sich dieser Durchgang in Richtung auf sein Auslaßende
verjüngt.
4· Form nach Anspruch 3, dadurch gekennzeichnet, daß die an diesen
Durchgang angrenzende Wand dieses Doms ebenfalls konisch bzw. spitz zuläuft.
