PURPOSE:To simplify a looper apparatus by arranging rollers at the both edges of a frame and clockwise turning the frame and adjusting the loop amount by controlling only the turning angle of the frame, in a looper apparatus for strip steel of the continuous hot press equipment. CONSTITUTION:A looper apparatus 2 for strip steel which is installed between a rolling mill group 3 and a bar-member jointing machine 1 consists of two pairs of pinch rollers 10 and 11, speed detectors 4 and 5, frame 12 which crosses with a pass line and is rotatable, looping rollers 7 and 8 arranged at the both edges of the frame 12, driving apparatus for revolving the frame 12, controller 6 for controlling the revolution, etc. Therefore, a loop is formed through the pushing-down operation of one looping roll 8 for the bar member 10 by the revolution of the frame 12 and the pushing-up operation of the other looping roll 7 for the bar member 10. The speed of the bar member 10 on the outlet side of the jointing machine and the speed on the inlet side of the rolling mill group are detected by the detectors 4 and 5, and the driving apparatus of the frame 12 is controlled according to the difference between the above-described detected values, and the loop amount can be adjusted.
