Abstract

An apparatus includes a press with dies configured to deform a strip of material by drawing material primarily from a width direction, a slitter set to cut the deformed strip to a uniform desired width dimension, and a roll-former with rolls configured to shape linear portions of the deformed and now uniform-width strip into a continuous beam. The apparatus further includes a welder for welding abutting edges of the sheet together to form a permanent tube, a sweep station for imparting a longitudinal shape to the continuous beam, and a cut-off for cutting the continuous beam into segments useful as vehicle bumper beams. A controller controls timing of various components. The beam segments are optimized in specific regions for local strength and minimized weight, and features can be incorporated into the beam segments such as coplanar mounting surfaces.
