Abstract

L'invention concerne un garnissage (3) pour une colonne d'échange de matière (1). Le garnissage est pourvu d'un premier disque (4), comportant une pluralité de premières tôles (10) de garnissage, et d'un deuxième disque (5), comportant une pluralité de deuxièmes tôles (18) de garnissage, le premier disque (4) de garnissage et le deuxième disque (5) de garnissage étant agencés l'un sur l'autre. Une face frontale (14) respective des premières tôles (10) de garnissage comporte une pluralité de premiers éléments de déformation (19), qui présentent un état non déformé avant que le premier disque (4) de garnissage et le deuxième disque (5) de garnissage ne soient agencés l'un sur l'autre, et un état déformé après que le premier disque (4) de garnissage et le deuxième disque (5) de garnissage aient été agencés l'un sur l'autre, pour la formation d'une pluralité de points de contact (23) entre les premières tôles (10) de garnissage et les deuxièmes tôles (18) de garnissage. Les premières tôles (10) de garnissage comportent chacune une partie (11), les premiers éléments de déformation (19) étant formés d'un seul tenant sur la partie (11) respective de tôle, et les premiers éléments de déformation (19) faisant saillie de la partie (11) de tôle.
