Abstract

Eine Vorrichtung zum Herstellen eines Spinnvlieses durch pneumatisches Abziehen und Ablegen schmelzge­ sponnener Filamente besteht aus einer mit der Schmelz­ spinndüse gasdicht verbundenen Überdruckkammer mit Austrittsöffnungen für die Filamente. Die Überdruckkammer verjüngt sich schwach konisch zu einem Verstreckschacht. Der Öffnungswinkel der schwach konischen Überdruckkam­ mer liegt unter 7°. Die Fäden werden un Form eines linearen Fadenvorhanges in das Innere der Überdruckkammer gesponnen, welche ebenso breit ist wie der Vorhang. Eine Seite des konischen Teils und des Verstreckschachts ist bewegbar und kann beim Beginn des Schmelzspinnens von der anderen Wand weg bewegt werden, so daß das Anspin­ nen erleichtert wird.
