Abstract
A computer controlled roll-forming apparatus is adapted to provide a repeating pattern of different longitudinal shapes to a continuous beam “on the fly” during the roll-forming process. A sweep station on the apparatus includes a primary bending roller tangentially engaging the continuous beam along the line level and an armature for biasing the continuous beam against the primary bending roller for a distance partially around a downstream side of the primary bending roller to form a sweep. Further, actuators adjustably move the armature at least partially around the downstream side of the primary bending roller between at least first and second positions for imparting multiple different longitudinal shapes into the continuous beam. In one form, the apparatus also includes a coordinated cut-off, so that when separated into bumper beam segments, the ends of the individual beam segments have a greater sweep than their center sections.
