ABSTRACT:
A method of forming finished piece-parts having a slight but variably adjusted three-dimensional bow from a continuous web. The method comprises the steps of advancing the web axially of its length by bowing the web in the same direction of desired bowing in the piece-part, laterally and/or axially of the web length, operable to impart set bows in the web slightly in excess of the desired finished piece-parts bowing, passing the bowed continuous web through a conventional stamping press, clamping and substantially flattening the bowed web between flat faces of cooperating die block and stripper plate components of the stamping press and stamping the clamped web between cooperating punch and die assemblies to deform the web to the desired configurations of the finished piece-parts.
