Title
(EN) AN EXTRUSION AND/OR PULTRUSION DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ D'EXTRUSION ET/OU DE PULTRUSION
Abstract
(EN)
An extrusion- or pultrusion device (1) for forming a profile product (2) in a production direction (Y), said device comprising:a rotating die (3) having two opposite first and second side walls (5, 6) and an outer circumferential surface (4) there between, wherein the rotating die (3) comprises a first side portion (23) in connection to the first side wall and a second side portion (25) in connection to the second side wall (6) and a mid-portion (22) extending between the first and second side portions (23, 25), wherein the first and/or second side portions (23, 25) comprises an recess (29) extending in a radial direction (R) with an extension being less than a radial extension of at least a part of the mid-portion (22).
(FR)
L'invention concerne un dispositif d'extrusion ou de pultrusion (1) pour former un produit de profil (2) dans une direction de production (Y), ledit dispositif comprenant : une matrice rotative (3) ayant deux première et deuxième parois latérales opposées (5, 6) et une surface circonférentielle externe (4) entre celles-ci. La matrice rotative (3) comprend une première portion latérale (23) en liaison avec la première paroi latérale et une deuxième portion latérale (25) en liaison avec la deuxième paroi latérale (6) et une portion médiane (22) qui s'étend entre les première et deuxième portions latérales (23, 25). La première et/ou la deuxième portion latérale (23, 25) comprennent un évidement (29) qui s'étend dans une direction radiale (R) avec une extension qui est inférieure à une extension radiale d'au moins une partie de la portion médiane (22).
