A cutoff unit for cutting a variably swept continuous beam extending from a roll forming mill includes a pickup subassembly for tracking a shape of the continuous beam, and a cutoff subassembly that engages and supports sides of the continuous beam while a blade slices transversely through the continuous beam. A controller connected to the roll forming mill and to the cutoff unit controls the cutoff unit to allow pass through of the continuous beam, and is configured to actuate the pickup and then actuate the blade to cut the continuous beam into longitudinally symmetrical beam segments, each having a center section (swept or not) and with mirror-image equally-swept end sections. |
