Abstract

Afin de nettoyer deux cylindres, ou plus, à l'aide d'un même dispositif de nettoyage de cylindre, deux tampons nettoyeurs, ou plus, sont utilisés, et les tampons nettoyeurs respectifs sont actionnés indépendamment de sorte que le tissu de nettoyage soit utilisé efficacement et que le gaspillage soit réduit. Un tissu de nettoyage (5) est déroulé d'un moyen d'alimentation en tissu de nettoyage (6), traverse un premier tampon nettoyeur (3) qui nettoie un premier cylindre (1), traverse ensuite un second tampon nettoyeur (4) qui nettoie un second cylindre (2), et après cela, est enroulé par un moyen d'enroulement de tissu de nettoyage (7). Un moyen de commande (12) maintient l'état d'utilisation du tissu de nettoyage correspondant au premier tampon nettoyeur, et commande un moyen d'entraînement de premier tampon (9), un moyen d'entraînement de second tampon (10), et un moyen d'entraînement de tissu de nettoyage (11), de sorte qu'une partie du tissu de nettoyage qui a été utilisée pour le premier tampon nettoyeur ne soit pas utilisée pour le second tampon nettoyeur.
