Abstract
To improve the productivity of the cold rolling facility by providing the cold rolling facility with a strip wiper free of dust and foreign matters suitable for high-speed rolling. The wiping ability was greatly improved by floating and supporting the wiper roll by the static pressure bearing of air of two-pocket type, and by variably adjusting the load range of the floating force in response to the plate width. At high-speed rolling exceeding 700 m/min which was incapable with the conventional roll wiper or tube wiper, the productivity of the cold rolling facility and the surface quality of the strip were greatly improved by applying to the cold rolling facility the wiping device whose wiping ability is equal to or better than the tube wiper at low speeds, and its effect is very large.
