Abstract

The arrangement is used for continuously cleaning surface-sensitive paper or film in web form. The arrangement may be installed at any point along the path of web travel. The cleaning effect is provided by a ribbon of fibrous nonwoven material which is guided over a suction roller together with the web to be cleaned. The ribbon of fibrous nonwoven material moves in the opposite direction to the web. A highly satisfactory cleaning effect is obtained by the high relative speed between the surface to be cleaned and the web of nonwoven material. The particles of dust and dirt removed from the web are drawn into the suction roller under the effect of the vacuum.
