Date Jul. 18, 1996It is desirable to accurately subject a process object region of a long edged strip material to notching and bending processes. A bending apparatus and a notching apparatus are used. The process object region of the long edged strip material which is passed through an outlet of a die member of the bending apparatus is subjected to a notching process conducted by the notching apparatus. Next, the process object region is subjected to a bending process performed by the bending apparatus. Finally, the process object region is cut off from a not-yet-processed region. An encoder measures a pulled-out amount of the edged strip material obtained when the edged strip material is pressed by a presser against a shaping face of the outlet of the stationary die so as to be bent. A servomotor is operated by a rotation number in which the measured value of the encoder is considered, so that the edged strip material is fed by a predetermined length.
