Abstract

Appareil de nettoyage et de conditionnement pour éponge à carrelage (10) utilisé pour le lavage à l’eau (12) d’une éponge (14) utilisée lors de la réalisation de joints pour des carreaux en céramiques. L’appareil (10) comprend un cadre (16) à placer dans l’eau (12). Ce cadre (16) se compose d’une première paroi (18) et d’une seconde paroi (20) espacée de la première (18). Un premier rouleau (22) possède un axe de rotation (24) s’étendant au travers des parois (18, 20) et un second rouleau (26) possède un axe de rotation (28) qui s’étend également au travers des parois (18, 20). Les rouleaux (22, 26) fonctionnent conjointement pour définir entre eux un chemin (P) pour le passage de l’éponge (14) à laver et à conditionner. Le dispositif est fait de telle manière que, lorsque les rouleaux (22, 26) tournent en sens inverse l’un par rapport à l’autre, l’éponge (14) est pressée et transportée dans le passage (P), où elle est lavée, puis conditionnée dans l’eau (12).
