PROBLEM TO BE SOLVED: To provide a rolling oil header not to generate an unevenness in the oil concentration while cutting-off in width. SOLUTION: The rolling oil header is equipped with a subheader 12 on the back of a main header 10 having lots of spray nozzles 11, and connected with a return pipe 13 and a supply pipe 14. An injection nozzle 19 is deeply inserted into the inside of the supply pipe 14 and a rolling oil is sprayed to a main header 10. Therefor, a circulation flow is formed in the header inside and the unevenness in the oil concentration is prevented. A slide or rotary means for changing the spray width can be arranged at the edge part of the main header 10. COPYRIGHT: (C)2004,JPO
