Abstract
(DE)
Verfahren zur Herstellung eines, vorzugsweise strangförmigen, Extrudates (40) mit den Schritten: Einführen einer erhärtbaren Matrix (44) und Fasern (45) bzw. eines Rohextrudates (41) in eine Pultrusionseinheit (6), Verformen des Rohextrudates (41) in der Pultrusionseinheit (6) indem eine Außenseite (51) des Rohextrudates (41) während des Bewegens des Rohextrudates (41) durch einen Pultrusionskanal (9) der Pultrusionseinheit (6) an wenigstens einer formgebenden Wandung (46) der Pultrusionseinheit (6) aufliegt, Austreten des verformten Rohextrudates (41) aus der Pultrusionseinheit (6), Einführen des aus der Pultrusionseinheit (6) ausgetretenen Rohextrudates (41) in eine Extrusionseinheit (7), Verformen des Rohextrudates (41) in der Extrusionseinheit (7) und Austreten des zu dem Extrudat (40) umgeformten Rohextrudates (41) aus einer Öffnung (60) der Extrusionseinheit (7), wobei in einem Schnitt durch das Rohextrudat (41) senkrecht zu der Bewegungsrichtung (54) des Rohextrudates (41) in dem Pultrusionskanal (9) ein erster Teil der Außenseite (51) des Rohextrudates (41) während des Bewegens durch die Pultrusionseinheit (6) an wenigstens einer formgebenden Wandung (46) der Pultrusionseinheit (6) aufliegt und ein zweiter Teil der Außenseite (51) des Rohextrudates (41) keinen Kontakt zu der wenigstens einen formgebenden Wandung (46) aufweist.
(EN)
The invention relates to a method for producing a preferably strand-type extrudate (40), comprising the following steps: introducing a curable matrix (44) and fibres (45) or a raw extrudate (41) into a pultrusion unit (6); shaping the raw extrudate (41) in the pultrusion unit (6) in which an outer side (51) of the raw extrudate (41) is in contact with at least one shaping wall (46) of the pultrusion unit (6) during the moving of the raw extrudate (41) through a pultrusion channel (9) of the pultrusion unit (6); removing the shaped raw extrudate (41) from the pultrusion unit (6); introducing the raw extrudate (41) removed from the pultrusion unit (6) into an extrusion unit (7); shaping the raw extrudate (41) in the extrusion unit (7); and removing the raw extrudate (41) shaped to form the extrudate (40) from an opening (60) of the extrusion unit (7); wherein, in a cross-sectional view through the raw extrudate (41) perpendicular to the movement direction (54) of the raw extrudate (41) in the pultrusion channel (9), a first part of the outer side (51) of the raw extrudate (41) is in contact with at least one shaping wall (46) of the pultrusion unit (6) during the moving through the pultrusion unit (6), and a second part of the outer side (51) of the raw extrudate (41) is not in contact with the at least one shaping wall (46).

La présente invention concerne un procédé de fabrication d’un extrudat (40), de préférence sous forme de corde, dont les étapes consistent : à introduire une matrice durcissable (44) et des fibres (45) ou un extrudat brut (41) dans une unité d’extrusion par tirage (6), à déformer l’extrudat brut (41) dans l’unité d’extrusion par tirage (6) en disposant une face extérieure (51) de l’extrudat brut (41) contre au moins une paroi formatrice (46) de l’unité d’extrusion par tirage (6) durant le déplacement de l’extrudat brut (41) à travers un canal (9) d’extrusion par tirage de l’unité d’extrusion par tirage (6), à extraire l’extrudat brut (41) déformé de l’unité d’extrusion par tirage (6), à introduire l’extrudat brut (41) extrait de l’unité d’extrusion par tirage (6) dans une unité d’extrusion (7), à déformer l’extrudat brut (41) dans l’unité d’extrusion (7) et à extraire l’extrudat brut (41) déformé en l’extrudat (40) hors d’une ouverture (60) de l’unité d’extrusion (7), une première partie de la face extérieure (51) de l’extrudat brut (41) est disposée contre au moins une paroi formatrice (46) de l’unité d’extrusion par tirage (6) durant le déplacement à travers l’unité d’extrusion par tirage (6) et une deuxième partie de la face extérieure (51) de l’extrudat brut (41) ne présentant aucun contact avec la ou les parois formatrices (46) dans une coupe à travers l’extrudat brut (41) perpendiculairement à la direction de déplacement (54) de l’extrudat brut (41) dans le canal (9) d’extrusion par tirage.
