ABSTRACT:
In an apparatus for manufacturing a taper leaf spring, by which after performing rolling on the edges of a sheet spring material in the direction of its breadth, rolling for tapering the sheet in the direction of its thickness is carried out, an edge roll assembly is employed for the sake of rolling in the breadth direction. In the edge roll assembly, constraining flanges for regulating the sheet thickness are provided on both ends of the main body of the edge roll so that expansion of both sides of a sheet spring material in the sheet thickness direction due to the effect of rolling in the sheet breadth direction is suppressed by the flanges and the thickness of a sheet spring material is kept uniform as a whole prior to performing rolling in the sheet thickness direction.
