摘要
A taper spring is manufactured by rolling a blank (B) in a single-spindle planetary rolling mill (10) having a vertically adjustable upper roll (11) and a planetary lower roll (12), while applying predetermined longitudinal tension to the blank (B) by a drawing chuck (18). A pair of feed rolls (16) provide feeding and braking forces and are preceded by a pair of edge rolls (20) defining the width of the material. The upper roll is controlled by a microcomputer to generate a desired taper profile to the blank.
