PURPOSE:To decrease the extent of slit distortion, by controlling an angle at which a slit strip comes into contact with a stripper, and giving it longitudinal bending deformation and reverse bending deformation both to be given to a slit edge just after biting. CONSTITUTION:In order to make a pass line of the broad metal belt 1 so far entered from the inlet side turn upward at a biting position, a slit strip receives longitudinal bending deformation for top compression. In succession, this strip is pushed up by a lower round blade 5', making it contact with the stripper 14 set up as tilted at a certain angle to horizontal line. And, it is advanced to the slitter outlet side as receiving bending deformation for underside compression such as offsetting forward bending deformation in the quite reverse direction to the bending deformation received at the biting position. Therefore, after slitting, there is no residual stress in the longitudinal bending deformation of a slit strip edge. So, a roller leveler leveling process is made unnecessary, thus quality is sharply improvable.
