PURPOSE:To roll out continuously any of round or flat bar or shapes in proper conditions by guiding a stock, to be rolled by a three-high mill, by the guides at inlet and outlet sides and a repeater, and absorbing the extended part of stock by the notched part of an inner wall at the inlet side of repeater or by releasing an outer wall actuated by detecting the biting of stock. CONSTITUTION:A rolling stock delivered from the lower stage of a three-high rolls 1 is fed to the upper stage of rolls 1 through an inlet side guide 2, a repeater 3, an outlet side guide 4 and pinch rolls 9. The stock is bent in the guides because the speed of stock at the inlet side of rolls is lower than the speed at the outlet side, but the bend is detected by a phototube 11 at the time of biting the stock to absorb the bend by releasing the outer wall 7 of repeater 3. When the release is troubled, the irregular deformation of stock is absorbed by allowing the stock to jut out through the notched opening 8 of the inner wall of repeater 3. Thus, any of round or flat bar or shapes is formed by continuously rolling a stock in proper conditions by using the three-high rolls 1.
