  • Method and apparatus for treating the surface of flexible tape-like material webs
    Patent number: 5658618
    Abstract: A method for reducing the abrasiveness of a coated product web is described, in which the product web is guided with its coated side over a deflection roller (2) and thereafter, in the course of a contact zone over guide rollers and deflection rollers or linear zones in between, is treated with itself, ie. once again with an abrasive surface. The abrasive action can be controlled in a specific manner through the relative speeds of the two surfaces, the tape tension and the length of the contact surface. Abraded particles present on the layer surface are subsequently removed by extraction.
