Abstract

Selon l'invention, un espacement est formé entre un rouleau de soutien (10) et un rouleau de chargement (20). Le rouleau de chargement (20) est constitué d'une structure de support fixe (21) et d'un manteau souple (22) conçu pour défiler autour de la structure de support en y appliquant son revers (22a) au moyen d'au moins un élément de soutien (23) qui presse ledit manteau souple (22) contre le rouleau de soutien (10). Le rouleau de chargement (20) comprend en outre au moins une rangée sensiblement axiale de points d'alimentation discrets (25, 26) d'un milieu sous pression, grâce à laquelle un flux du milieu sous pression à coefficient de pression et/ou d'écoulement contrôlé peut être alimenté par les points d'alimentation (25, 26) de ladite rangée, contre le revers (22a) du manteau souple (22). Selon le procédé de l'invention, le milieu sous pression alimenté par les points d'alimentation (26) sert au façonnage sens travers (CD) de la bande continue de papier ou de carton passant par l'espacement (N).
