ABSTRACT:
Apparatus for cleaning particulate matter from a moving web, such apparatus being held in effective cleaning contact therewith. The apparatus includes a member, which is at least partially formed of magnetically attractable material, for engaging the surface of a moving web to be cleaned. Such member is held in cleaning contact with such web by a magnet which is located adjacent to the surface of the web opposite to the surface to be cleaned, and which induces a magnetic field which attracts the member to the web.
