Description

Verfahren zur Herstellung von Spinndüsen. Es ist an sich bekannt, Spinndüsen zur Herstellung von Kunstfäden dadurch herzustellen, daß man Metalldrähte in eine gießbare Masse, etwa Glas, einbettet und dann die Drahtteile durch Herauslösen entfernt. So hat -der Erfinder selbst vorgeschlagen, zur Einbettung der Metalldrähte ein Formaldehyd-Kondensationsprodukt zu verwenden. Bei dem bisher bekannten einschlägigen Verfahren macht das Einspannen der Drähte große Mühe. Lm in dieser Beziehung eine Verbesserung zu erzielen, geht die Erfindung grundsätzlich einen vollständig abweichenden Weg zur Zusammenstellung des Düsenkörpers aus den Drähten und der sie umgebenden plastischen blasse. Es wird hierbei das an sich bekannte Verfahren benutzt, einen Draht von beliebiger Länge fortlaufend mit Preßmassen zu umgeben, wie es bereits seit langem zur Isolation von Kupferdrähten benutzt wird.Process for the manufacture of spinnerets. It is known per se Manufacture spinnerets for the production of synthetic threads by making metal wires embedded in a pourable mass, such as glass, and then the wire parts by detaching them removed. The inventor himself proposed embedding the metal wires to use a formaldehyde condensation product. In the previously known relevant This procedure makes clamping the wires very difficult. Lm one in this regard To achieve improvement, the invention is basically a completely different one Way of assembling the nozzle body from the wires and those surrounding them plastic pale. The method known per se is used here, one Continuously surrounding wire of any length with molding compound, as it was already done has long been used to insulate copper wires.

Nach der Erfindung soll ein fortlaufender Metalldraht zunächst mit der plastischen Masse, die in Phenol-Formaldehyd-Kondensationsprodukten, Kautschuk, Guttapercha o. dgl. bestehen kann, in der Weise umzogen, umpreßt oder umgössen werden, daß eine nachherige Berührung der Drähte ausgeschlossen ist. Man zerlegt dann den Draht in Stücke von geeigneter Länge, vereinigt diese zu Bündeln und führt die Härtung oder Vulkanisierung durch. Es entsteht ein zylindrischer oder kantiger Körper, der dann in bekannter Weise unterteilt werden kann, worauf man aus den so entstandenen Platten die Drahtteile herauslöst.According to the invention, a continuous metal wire should initially be included the plastic mass contained in phenol-formaldehyde condensation products, rubber, Gutta-percha or the like can consist of being moved, pressed or poured over, that subsequent contact with the wires is impossible. You then dismantle the Wire into pieces of suitable length, combine them into bundles and carry out the hardening or vulcanization. The result is a cylindrical or angular body, the can then be subdivided in a known manner, whereupon one can derive from the resulting Plates detaching the wire parts.

Der große Vorzug des neuen Verfahrens liegt in der einfachen, billigen .und zum großen Teil maschinellen Herstellung und in der Möglichkeit, aus den einzelnen, durch Zerschneiden des Drahtes gewonnenen Strängen Körper jedes gewünschten Durchmessers und jeder gewünschten Länge herzustellen, wobei die Drähte ohne Einspannen ganz gleichmäßig auf dem Querschnitt verteilt werden. Is bietet sich- tlie Möglichkeit, Drähte von jeder gewünschten Länge und beliebigem Querschnitt auf die einfachste Weise mit einer beliebig dicken Schicht einer beliebigen Knet- oder preßbaren ?nasse zu überziehen.The great advantage of the new process is that it is simple and cheap and, to a large extent, machine production and the possibility of individual, strands of any desired diameter obtained by cutting the wire and any desired length, leaving the wires intact without clamping evenly distributed over the cross-section. It is possible to Wires of any desired length and any cross-section to the simplest Way with any thick layer of any kneadable or pressable wet to cover.
