Abstract
Apparatus for cleaning magnetic tape and like webs, comprising a series of sharp scraping edges for cleaning said web, said edges forming the periphery of a series of air ports through which a vacuum is drawn laterally across the bottom of the web. Thus the apparatus can be utilized to perform a novel cleaning process wherein the cleaning edges are constantly washed with air. Air-distributing means is provided whereby there is no situs on the tape being cleaned on which loose debris can be immobilized in a zone of stagnant air during its entire passage through the apparatus.
