Abstract

PURPOSE:To produce a uniform taper spring by braking work rolls and controlling the expansion of the width of the spring plate to a minimum. CONSTITUTION:A material 1 heated to a fixed temperature is carried on a work table 2 by a clamp 15 and placed on a guide plate 14 with the front edge located between a pair of work rolls 9 and 10. The material plate 1 is then subjected to first rolling between the work rolls 9 and 10 under the control of an automatic pressure regulator 12 and the taper guide plate 14 as a movable base 4 is retracted. A taper spring of a fixed dimension is finished by the repetition of the said procedure.
