SURFACE TREATMENT PROCESS AND DEVICE FOR FLEXIBLE ELONGATED WEBS OF MATERIAL

摘要

A process is disclosed for reducing the abrasivity of a coated web of material. The web of material runs with its coated side over a deflecting roller (2) and is then treated with an abrasive surface, either along a contact path via guiding or deflecting rollers or along intermediate linear paths in contact with itself. By modifying the relative speeds of both surfaces, the web tension and the length of the contact surface, the abrasion effect may be appropriately adjusted. Rubbed-off particles lying on the surface of the web are sucked off.
