    • The invention there is relates a web cleaning apparatus (10) comprising: a pair of operatively rotating cleaning rollers (14) operatively disposed on opposite sides of the web (12) ; a housing (20) surrounding a major part of the surface of each roller (14) ; a vacuum chamber (22) substantially co-extensive with each roller (14) ; a longitudinal slot extending parallel to each roller (14) and substantially co-extensive therewith, the slot having an inlet (24) proximate the roller surface and an outlet (26) in communication with the vacuum chamber (22) and operatively providing an air flow path from adjacent the roller (14) into the vacuum chamber (22), wherein the air flow speed at each inlet (24) is not less than the surface speed of the rollers (14), and a method of using such apparatus (10). Another apparatus of the invention includes a housing (20) surrounding the roller (14) and spaced therefrom with a gap (21) of about 0.5mm to about 5mm. Further embodiments of the invention provide a shutter (206) for controlling the air flow around the roller (14) in a cleaning step. Further embodiments of the invention provide a valve (122A) controlled bypass line (120A) whereby a given portion of a web cleaning apparatus (10) can communicate with the atmosphere such that it is not under vacuum.
