Description

Vorrichtung zum gleichmäßigen Strecken frisch gesponnener Kunstseidenfäden Bei der Herstellung von Kunstseide wird der frisch erzeugte Spinnfaden vielfach einer Knickung oder Streckung unterworfen, um ihm bestimmte Eigenschaften zu erteilen. So ist beispielsweise vorgeschlagen worden, den Spinnfaden über mehrere Glasstäbe unter mehr oder weniger starker Ablenkung aus der Laufrichtung zu ziehen oder zur Vergleichmäßigung der durch solche Knickung erzeugtenSpannung eine federnd aufgehängteFadenführung anzuwenden.Device for evenly stretching freshly spun rayon threads In the manufacture of rayon, the freshly produced spinning thread is used many times over subjected to buckling or stretching in order to give it certain properties. It has been proposed, for example, that the spun thread over several glass rods to pull out of the running direction with more or less strong distraction or towards A resiliently suspended thread guide is used to even out the tension generated by such a kink apply.

Die Erfindung bezweckt, die gleichmäßige Streckung des Fadens auf eine neuartiger Weise, nämlich durch labile Gewichtsbelastung, zu erreichen, wobei eine nennenswerte Knickung nicht erforderlich ist. Eine Druckvorrichtung, die mit ihrem Eigengewicht auf den Faden wirkt, wird dem Spinnfaden an-oder aufgelegt, wobei das wirksame Gewicht so leicht schwenkbar angeordnet ist, daß es bei Spannungsschwankungen sich hebt oder senkt. Auf diese Weise wird nun, ohne daß eine merkliche Knickung im Fadenlauf auftritt, eine gelinde Druck- und dadurch eine Streckwirkung ausgeübt, die den Fadenzug vergleichmäßigt. Man ist so in der Lage, durch passende Bemessung dieser Belastung vollkommen gleichmäßige Erzeugnisse mit bestimmten physikalischen Eigenschaften, wie Elastizität, Reißfertigkeit u. dgl., zu erzielen.The aim of the invention is to ensure that the thread is stretched evenly to achieve a novel way, namely by unstable weight loading, whereby a significant buckling is not required. A printing device that works with their own weight acts on the thread, the spun thread is attached or laid on, whereby the effective weight is so easily pivoted that it is in the event of voltage fluctuations rises or falls. In this way it is now without any noticeable kinking occurs in the grain, a gentle pressure and thus a stretching effect is exerted, which even out the string. One is able to do so through appropriate dimensioning this load perfectly uniform products with certain physical Properties such as elasticity, tear resistance and the like. To achieve.

Es ist besonders vorteilhaft, die Einwirkung nahe der Spinndüse erfolgen zu lassen, also in einem Zustand, in dem der Faden noch eine geringe Festigkeit besitzt. Ist man genötigt, ein Spinnverfahren anzuwenden, bei dem der Faden Knicke durchlaufen muß, so schließen diese die Verwendung einer labilen Gewichtseinwirkung nicht aus, die dann in der Knickstelle angreift. Endlich kann man die Gewichtswirkung der Vorrichtung steigern durch Zusatzgewichte. Die Vorrichtungen werden entweder neben den bisher gebräuchlichen Fadenführern verwendet oder sie werden mit diesen vereinigt.It is particularly advantageous for the action to take place near the spinneret to leave, i.e. in a state in which the thread still has a low strength owns. Is it necessary to use a spinning process in which the thread kinks? must go through, these preclude the use of an unstable weight action not off, which then attacks the kink. Finally you can see the weight effect increase the device through additional weights. The devices will either in addition to the previously common thread guides or they are used with these united.

Die beiliegenden Zeichnungen zeigen beispielsweise in Abb. i, 2, 3 schematisch die Anordnung der Vorrichtung beim Spinnen, in Abb. q., 5, 6, 7 Ausführungsarten der Vorrichtung. Abb. i zeigt ein schräges Spinnen, wobei das um a leicht bewegliche Gewicht b auf den Faden einwirkt, der von der Düse c über einen Fadenführer d zu dem Aufnahmeteil e gelangt; die Gewichtsbelastung findet hier innerhalb des Spinnbades statt. Abb.2 zeigt eine Anordnung mit doppelter Gewichtsbelastung, und zwar einmal in der Nähe der Düse innerhalb des Spinnbades mit der um a1 leicht beweglichen Vorrichtung b1, sodann außerhalb des Spinnbades mit dem um a2 leicht beweglichen Gewicht b2. Abb. 3 zeigt ein schrägsenkrechtes Spinnen mit dem um a3 leicht beweglichen Gewicht b8.The accompanying drawings show, for example, in Figs. I, 2, 3 schematically the arrangement of the device during spinning, in Fig. q., 5, 6, 7 embodiments the device. Fig. I shows an oblique spinning, the one that is easily movable around a Weight b acts on the thread coming from the nozzle c via a thread guide d to the receiving part e arrives; the weight load takes place here within the spinning bath instead of. Figure 2 shows an arrangement with double weight loading, namely once in the vicinity of the nozzle inside the spinning bath with the device which can be easily moved by a1 b1, then outside the spinning bath with the weight b2, which is easily movable by a2. Fig. 3 shows an inclined perpendicular spinning with the weight easily movable by a3 b8.

Dabei kann die Vorrichtung nach Bedarf verschiedenartig ausgebildet sein; z. B. wie in den Abb. q. bis 7 dargestellt, wobei, wie in Abb. 7 angedeutet ist, die Gewichtsbelastung durch Gewichte f verändert werden kann; jeweils stellt in den Abb. q. bis 7 a den Schenkel dar, in dem die Schwenkung stattfindet, b den beweglichen Schenkel. Die Vorrichtungen in Abb. 5 und 7 sind beispielsweise als Fadenführer g, h und i ausgebildet.The device can be designed in various ways as required; z. B. as in fig. Q. to 7, wherein, as indicated in Fig. 7, the weight load can be changed by weights f; each represents in Fig. q. to 7 a represents the leg in which the pivoting takes place, b the movable leg. The devices in Fig. 5 and 7 are designed as thread guides g, h and i, for example.
