PROBLEM TO BE SOLVED: To provide a rolling oil header to keep the oil concentration uniform while cutting-off in width. SOLUTION: The rolling oil header is equipped with two symmetrical ejectors 12 in the header main body 10 having lots of spray nozzles 11. These ejectors 12 are arranged outward or inward. The rolling oil is supplied from a rolling oil supply nozzle 18 and sprayed from an injection nozzle 16, and the surrounding oil is aspirated from a negative pressure part 13 and so a strong circulation flow occurs in the header body 10. Therefor, separation of the rolling oil component does not occur and the oil concentration can be uniform to make 'cutting-off in width' possible in a practical line. COPYRIGHT: (C)2004,JPO
