Abstract
PURPOSE:To extend the service life of rolling rolls, and to reduce the freqency of replacement of rolling rolls, by making the effective length of the rolling roll for the flat spring larger than the rolling breadth for the flat spring, and by making the axial position of the rolling roll variable. CONSTITUTION:The longitudinal effective length of rolling rolls 1, 2 is made larger than twice the maximum rolling length for a flat spring. These rolling rolls 1, 2 are driven to rotate, and the upper roll 1 is controlledly shifted vertically in order to give a desired taper to the flat spring. If one of the rolling rolls 1, 2 is abraded during the rolling work, the rolling work is temporarily interrupted, and the positions of the rolling rolls 1, 2 are longitudinally shifted by a driving mechanism 6; then, the rollig work is restarted using the unabraded other parts of the rolling rolls 1, 2. By the present method, the apparent service life of rolling center is made constant so that the generation of an eccentric loading and troubles due to it are prevented.
