Description
<Desc/Clms Page number 1>
Vorrichtung zum kontinuierlichen Nassbehandeln laufender Fadenscharen. Es ist bereits vorgeschlagen worden, laufende Fadenscharen aus frisch gesponnener Kunstseide in der Weise zu behandeln, dass man die Fäden unter Zuhilfenahme von Barken nach dem sogenannten Filmnaehbeharnd- lungsprinzip also in auf- und absteigendem Laufe durch Wasch- und Nachbehandlungsbäder hindurchfährt, sodann trocknet und schliesslich auf einen Kettbaum aufwickelt. Die L mlenkwalzen für die Fadenschar sind dabei so angeordnet, dass die untern Walzen tief in die Badflüssigkeit eintauchen und die obern ausserhalb der Badflüssigkeit liegen.
Dies führt indessen zu dem Übelstand, dass mitunter einige der eng benachbarten Fäden der Fadenschar zusammenlaufen, ein Übelstand, der natürlich unter allen Umständen vermieden werden muss.
Überraschenderweise hat sich ergeben, dass das Zusammenlaufen von Fäden sofort dann aufhört, wenn auch die obern Walzen entweder ganz oder mindestens bis etwas über die Mitte in die Badflüssigkeit eintauchen, also so weit, dass die Fäden bereits auf der Walze liegen, wenn sie beim Weiterdrehen der Walze schliesslich aus dem Bad heraustreten. Indessen ist eine Einschränkung insofern zu machen, als die letzte obere Walze rieht ganz ins Bad eintauchen darf, aber bis über die Hälfte in das Bad eintauchen muss. Wird diese Bedingung des über die Hälfte Eintauchens nicht erfüllt, so müssen die Fäden, bevor sie zur Auflage auf die obere Walze kommen, noch ein kleines Stück nach dem Austreten aus dem Bad in freier Luftstrecke laufen.
Dabei entsteht die Gefahr, dass die ziemlich nahe nebeneinanderlaufen- den Fäden häufig zusammenlaufen und nur sehr schlecht wieder voneinander getrennt werden können. Dieser Übelstand wird durch das Eintauchen der Walze bis über die Hälfte vermieden.
Es hat sich ferner gezeigt, dass ein Zusammenlaufen von Fäden auf den Überleit- walzen zusätzlich noch dadurch mit Erfolg

bekämpft werden kann, da.ss die Luftstrecke kurz gehalten wird.

Device for the continuous wet treatment of moving sheets of thread. It has already been proposed to treat running strands of freshly spun rayon in such a way that the threads are passed through washing and post-treatment baths in an ascending and descending manner with the help of barges, then dried and finally on a warp beam. The guide rollers for the thread sheet are arranged in such a way that the lower rollers are deeply immersed in the bath liquid and the upper ones are outside the bath liquid.
However, this leads to the inconvenience that sometimes some of the closely spaced threads of the group of threads converge, an inconvenience which of course must be avoided under all circumstances.
Surprisingly, it turned out that threads stop running together immediately when the upper rollers are immersed in the bath liquid either completely or at least slightly above the middle, i.e. so far that the threads are already on the roller when they continue to rotate the roller finally step out of the bath. However, a restriction must be made insofar as the last upper roller may be completely immersed in the bath, but must be more than halfway immersed in the bath. If this condition of more than half of the immersion is not met, the threads must run in the open air for a short distance before they come to rest on the upper roller.
The danger arises that the threads running fairly close to one another often converge and can only be separated from one another with great difficulty. This inconvenience is avoided by submerging the roller by more than half.
It has also been shown that threads converge on the transfer rollers with success as a result

can be combated, that the air gap is kept short.
