Abstract:
A system for cleaning particles from a web substrate having first and second surfaces, the web substrate being conveyed along a conveyance path by conveyance rollers and having a free span of said web substrate between adjacent ones of said conveyance rollers, comprising:a) a first contact cleaning roller rollably disposed transversely against one of said first and second surfaces to be cleaned, said disposition being on said free span of said web, said web being wrapped on said contact cleaning roller at a radial angle of said roller between 0.degree. and about 180.degree.; andb) means for controllably oscillating said contact cleaning roller axially of itself while rolling along said surface to be cleaned, wherein said web is conveyed at a first linear velocity and said contact cleaning roller is oscillated at a second linear velocity, and wherein the ratio of said second velocity to said first velocity is less than 0.01, and wherein tension in said web is greater than 0.5 pound per linear inch of web width.
