PROBLEM TO BE SOLVED: To provide a continuous press processing method and its device capable of feeding a workpiece at high speed and with high precision (trace amount). SOLUTION: In the continuous press processing method, slitting is performed to make an opening on a workpiece by means of a metallic die set on a press and then, while tension is imparted to the exit side of the die to the extent that the workpiece with slitting performed is free from the slack, primary rolling is carried out to correct the step-wise state of the workpiece. Then, if the opening of the slit is less than the desired size, the tension is increased to keep correcting the opening, with the warpage of the workpiece corrected simultaneously, and with the thickness of the workpiece formed to a desired level. If the opening of the slit has the desired size the tension for the workpiece is maintained as it is, with the warpage of the workpiece corrected, and with a secondary rolling performed for the purpose of forming the desired thickness of the workpiece.
