Abstract

A metal strip 21 for forming a taper leaf spring has its width reduced by passing it through grooved rolls 22a, 22b which have flanges 4 on either side of the grooves to constrain the expansion of the thickness of the strip at its edges. The rolls can be controlled in dependence on the contour of a template 21a. <IMAGE>
