Abstract

PURPOSE:To perform marking on defect detected parts accurately at all times by providing an opening part to the cylindrical part of a marking roll, disposing a reflecting mirror to right thereunder, and directing laser beam thereto. CONSTITUTION:A steel strip 1 under transfer is detected with a steel strip defective part detector 2, and the result of the detection is conducted to a tracking device 3. When a defective part detecting position arrives at a marking roll 5, a signal is introduced to a laser oscillation control device 6 from the device 3. Thence, an instruction is given from this device 6 to a laser beam irradiating device 7, and a laser beam is directed to the reflecting mirror 11 disposed right under the opening part 10 opened in the cylindrical part 9 of the roll 5. This laser beam is irradiated to the defect detecting part of the steel strip 1 through the mirror 11 and the part 10, whereby the marking is applied.
