Title
(EN) A METHOD OF MANUFACTURING FIBROUS CORES
(FR) PROCÉDÉ DE FABRICATION DE CŒURS FIBREUX
Abstract
(EN) The present disclosure is directed to a method for manufacturing a fibrous core comprises: providing a strip comprising at least one liner, and at least one fluted layer, wherein the strip has a leading edge, a trailing edge, a first strip face, a second strip face, and a strip axis substantially parallel to at least one of the leading edge and the trailing edge; feeding the strip to a mandrel having a central longitudinal axis extending in a longitudinal direction; winding the strip onto the mandrel such that the leading edge of the strip overlaps the trailing edge of the strip to form a fibrous core comprising an inner surface, an outer surface, and a longitudinal core axis; and adhering the leading edge to the trailing edge of the strip to from an overlap portion having an overlap width.
(FR) La présente invention concerne un procédé de fabrication d'un cœur fibreux, comprenant les étapes suivantes : une étape consistant à mettre à disposition une bande comprenant au moins un chemisage, et au moins une couche cannelée, la bande comportant un bord d'attaque, un bord de fuite, une première face de bande, une seconde face de bande, et un axe de bande sensiblement parallèle au bord d'attaque et/ou au bord de fuite ; une étape consistant à envoyer la bande vers un mandrin ayant un axe longitudinal central s'étendant dans une direction longitudinale ; une étape consistant à enrouler la bande sur le mandrin de façon à ce que le bord d'attaque de la bande recouvre le bord de fuite de la bande afin de former un noyau fibreux comprenant une surface interne, une surface externe, et un axe de cœur longitudinal ; et une étape consistant à coller le bord d'attaque avec le bord de fuite de la bande afin de former une partie de recouvrement présentant une certaine largeur de recouvrement.
