Gegenstand der Patentanmeldung V 9771 VII a/29 a ist eine Spinndüse zur Herstellung von Fäden mit Lufteinschlüssen aus der Schmelze synthetischer linearer Hochpolymerer, wie Polyamiden, Polyestern u. dgl., bei welcher die Düsenöffnungen aus mehreren in Kreis- oder Ellipsenform in geringem Abstand voneinander angeordneten Kreisbögen oder Segmenten bzw. entsprechenden Teilen einer Ellipse bestehen. Die Bezeichnungen Kreis und Ellipse werden dabei nicht im streng mathematischen Sinn verstanden, es fallen darunter auch Anordnungen gerader Schlitze, die etwa die Figur eines Kreises oder einer Ellipse bilden.The subject of patent application V 9771 VII a / 29 a is a spinneret for the production of threads with Air pockets from the melt of synthetic linear high polymers such as polyamides, polyesters and the like, in which the nozzle openings from several in a circular or elliptical shape at a small distance mutually arranged arcs or segments or corresponding parts of an ellipse exist. The terms circle and ellipse are not used in a strictly mathematical sense understood, it also includes arrangements of straight slots, roughly the shape of a circle or form an ellipse.
Die in der Patentanmeldung V 9771 VII a/29 a dargestellten Düsenöffnungen lassen nur Formen erkennen, die einen runden oder unrunden, jedoch keinen gelappten Querschnitt mit Lufteinschlüssen ergeben. Derartige profilierte Formgebilde mit Lufteinschlüssen werden ersponnen; wenn bei Düsenöffnungen, die nach Patentanmeldung V 9771 VIIa/ 29 a aus mehreren, in Form eines Kreises oder einer ähnlichen Figur in geringem Abstand voneinander angeordneten Schlitzen bestehen, erfindungsgemäß der Flächeninhalt des metallischen Kerns, welcher das Innere der Schlitzanordnung bildet, größer ist als das Quadrat der eineinhalbfachen Schlitzbreite und die Schlitze aus der Richtung einer Tangente der mehr oder weniger kreisförmigen Schlitzanordnung unter gleichzeitiger Schlitzverlängerung etwas nach außen gedreht sind, derart, daß das innere Ende jedes Schlitzes jeweils mit geringem Abstand der Längsseite des benachbarten Schlitzes gegenüberliegt und daß das äußere Ende jedes Schlitzes um mindestens das Zweifache der Schlitzbreite über das ihm gegenüberliegende Ende des benachbarten Schlitzes herausragt. Auch in geringem Abstand voneinander angeordnete Schlitze, die ein Vier- oder Vieleck oder annähernd derartige Formen ergeben, sind verwendbar. Die Schlitze können sowohl gebogene als auch gerade Gestalt aufweisen.The nozzle openings shown in patent application V 9771 VII a / 29 a only show shapes which have a round or out-of-round, but not lobed cross-section with air pockets result. Profiled shapes of this type with air pockets are spun; if at nozzle openings, according to patent application V 9771 VIIa / 29 a of several, in the form of a circle or consist of a similar figure at a small distance from each other arranged slots, according to the invention the surface area of the metallic core which forms the interior of the slot arrangement, is greater than the square of one and a half times the slot width and the slots out of direction a tangent of the more or less circular slot arrangement with simultaneous slot extension are rotated slightly outward, so that the inner end of each slot each with a slight Distance of the longitudinal side of the adjacent slot is opposite and that the outer end of each slot by at least twice the slot width across the opposite end of the adjacent slot protrudes. Even slots arranged a short distance from one another, which result in a square or polygon or approximately such shapes can be used. the Slots can have both curved and straight shapes.
Einige der vielen möglichen Schlitzanordnungen nach der Erfindung sind in den F i g. 1 bis 3 der
Zeichnung in stark vergrößertem Maßstab dargestellt. Dort ist mit 1 der metallische Kern, mit 2 das
innere und mit 3 das äußere Ende der Schlitze bezeichnet. Die verschiedensten Abarten derartiger
Schlitzanordnungen sind möglich, indem beispielsweise die Länge der Schlitze ungleichmäßig ist, gerade
und gebogene Schlitze miteinander kombiniert werden oder mehrere Schlitzanordnungen, die ein hohles
Formgebilde ergeben würden, gleicher oder unterSpinndüse zur Herstellung von Fäden, Fasern,
Bändchen u. dgl. mit Lufteinschlüssen aus der
Schmelze synthetischer linearer HochpolymererSome of the many possible slot arrangements of the invention are shown in FIGS. 1 to 3 of the drawing shown on a greatly enlarged scale. There, 1 denotes the metallic core, 2 denotes the inner and 3 denotes the outer end of the slots. The most diverse variations of such slot arrangements are possible, for example by the length of the slots is uneven, straight and curved slots are combined with each other or several slot arrangements that would result in a hollow shape, the same or below a spinning nozzle for the production of threads, fibers,
Ribbons and the like with air pockets from the
Melt synthetic linear high polymers

Je nach der gewählten Gestalt der Schlitzanordnung werden Formgebilde mit Lufteinschlüssen und mehr oder weniger ausgeprägtem Profil erhalten, die die vorteilhaften Eigenschaften der Hohlgebilde mit denen der profilierten Formgebilde in sich vereinigen und sowohl für textile als auch für technische Zwecke hervorragende Bedeutung erlangen können.Depending on the selected shape of the slot arrangement, shapes with air inclusions and obtained more or less pronounced profile, which has the advantageous properties of the hollow structure unite those of the profiled shapes and for both textile and technical purposes can attain outstanding importance.
