Abstract

La présente invention concerne un procédé d'obtention d'un profil de lame d'essuie-glace (100) dans lequel on obtient un profil (1) d'au moins une lame d'essuie-glace (2) par extrusion à travers une buse d'extrusion, la lame d'essuie-glace (2) comportant une lèvre d'essuyage (4) destinée à racler une surface vitrée et un talon (3) dans lequel est ménagé au moins un canal longitudinal (6) dans lequel un fluide de lavage est destiné à circuler, caractérisé en ce qu'en sortie de la buse d'extrusion : - le profil (1) d'au moins une lame d'essuie-glace (2) présente un canal longitudinal (6) ouvert par une fente longitudinale (10) ménagée du côté opposé à celui de la lèvre d'essuyage (4), et - ledit profil (1) d'au moins une lame d'essuie-glace (2) obtenu est posé sur une surface de pose (11) avant que le matériau élastomère ait durci, en étant orienté sur la surface de pose (11) de manière que les parois (10a, 10b) en vis-à-vis de la fente longitudinale (10) soient placées l'une au-dessus de l'autre, la paroi supérieure (10a) tombant sur la paroi inférieure (10b) par gravité de façon à refermer le canal longitudinal (6) par durcissement du matériau élastomère.The present invention relates to a method for obtaining a wiper blade profile (100) in which a profile (1) of at least one wiper blade (2) is obtained by extrusion through an extrusion nozzle, the wiper blade (2) comprising a wiping lip (4) intended to scrape a glazed surface and a heel (3) in which at least one longitudinal channel (6) is provided in which a washing fluid is intended to circulate, characterized in that at the outlet of the extrusion nozzle: - the profile (1) of at least one wiper blade (2) has a longitudinal channel (6 ) opened by a longitudinal slot (10) formed on the side opposite that of the wiper lip (4), and - said profile (1) of at least one wiper blade (2) obtained is placed on a laying surface (11) before the elastomeric material has hardened, being oriented on the laying surface (11) so that the walls (10a, 10b) facing the longitudinal slot (10) are placed one above the other, the upper wall (10a) falling on the lower wall (10b) by gravity so as to close the longitudinal channel (6) by hardening of the elastomeric material.
