Title (EN) MULTI-COMPONENT EXTRUSION SPRAY HEAD, MULTI-COMPONENT EXTRUSION SYSTEM AND METHOD FOR PRODUCING A COMPOSITE TUBE
(FR) TÊTE D'EXTRUSION À PLUSIEURS COMPOSANTS, INSTALLATION D'EXTRUSION À PLUSIEURS COMPOSANTS ET PROCÉDÉ POUR LA FABRICATION D'UN TUYAU FLEXIBLE COMPOSITE
(DE) MEHRKOMPONENTEN-EXTRUSIONSSPRITZKOPF, MEHRKOMPONENTEN-EXTRUSIONSANLAGE UND VERFAHREN ZUM HERSTELLEN EINES VERBUNDSCHLAUCHS
Abstract:
(EN) The invention relates to a multi-component extrusion spray head (13) for producing a composite tube (I), comprising an extrusion nozzle (29), a main spray head (18), which is configured for supplying the extrusion nozzle (29) with a first melt flow (16) and a second melt flow (17), wherein the first melt flow (16) and the second melt flow (17) are guided separately from one another in the extrusion nozzle (29) in a conveying direction (F) oriented away from the main spray head (18) in the direction of a nozzle outlet (38) of the extrusion nozzle (29), as well as comprising a melt flow distributer device (34), arranged in the extrusion nozzle (29) and outside the main spray head (18), which is configured for distributing the first melt flow (16) in a peripheral direction (U16) thereof, and which is configured for supplying the second melt flow (17) to the distributed first melt flow (16) in such a way that at least one section (62, 63) of the second melt flow (17) is arranged within the first melt flow (16) in the peripheral direction (U16).
(FR) L'invention concerne une tête d'extrusion (13) à plusieurs composants pour la fabrication d'un tuyau flexible composite (1), comportant une buse d'extrusion (29), une tête d'extrusion de base (18) qui est conçue pour amener à la buse d'extrusion (29) un premier flux de matière fondue (16) et un second flux de matière fondue (17), le premier flux de matière fondue (16) et le second flux de matière fondue (17) étant envoyés séparément l'un de l'autre dans la buse d'extrusion (29), dans une direction d'avance (F) qui est orientée, en partant de la tête d'extrusion de base (18), dans la direction d'une sortie (38) de la buse d'extrusion (29), et un dispositif (34) répartiteur de flux de matière fondue, disposé dans la buse d'extrusion (29) et à l'extérieur de la tête d'extrusion de base (18), dispositif qui est conçu pour répartir le premier flux de matière fondue (16) dans une direction périphérique (U16), et qui est conçu pour envoyer le second flux de matière fondue (17) au premier flux de matière fondue (16) réparti, de telle sorte qu'au moins un segment (62, 63) du second flux de matière fondue (17) soit disposé dans la direction périphérique (U16) à l'intérieur du premier flux de matière fondue (16).
(DE) Ein Mehrkomponenten-Extrusionspritzkopf (13) zum Herstellen eines Verbundschlauchs (l), mit einer Extrusionsdüse (29), einem Grundspritzkopf (18), der dazu eingerichtet ist, der Extrusionsdüse (29) einen ersten Schmelzestrom (16) und einen zweiten Schmelzestrom (17) zuzuführen, wobei der erste Schmelzestrom (16) und der zweite Schmelzestrom (17) in einer Förderrichtung (F), die von dem Grundspritzkopf (18) weg in Richtung eines Düsenaustritts (38) der Extrusionsdüse (29) orientiert ist, getrennt voneinander in der Extrusionsdüse (29) geführt sind, und einer in der Extrusionsdüse (29) und außerhalb des Grundspritzkopfs (18) angeordneten Schmelzestromverteileinrichtung (34), die dazu eingerichtet ist, den ersten Schmelzestrom (16) in einer Umfangsrichtung (U16) desselben aufzuteilen und die dazu eingerichtet ist, den zweiten Schmelzestrom (17) dem aufgeteilten ersten Schmelzestrom (16) derart zuzuführen, dass zumindest ein Abschnitt (62, 63) des zweiten Schmelzestroms (17) in der Umfangsrichtung (U16) innerhalb des ersten Schmelzestroms (16) angeordnet ist.
