ABSTRACT:
A rolling mill machine is for longitudinal bending of plate to selectively provide one of at least two cross-sectional profiles. The machine includes a plurality of shaping stations extending transversely of the plate with at least one drive station for advancing the plate through the plurality of shaping stations. Each of the shaping stations has a first forming element on one side of the plate and a second forming element on the other side of the plate. The first forming element has at least a first set of non-driven forming rolls and a second set of non-driven forming rolls. The second forming element has a plurality of non-driven forming rolls. The first forming element is selectively moveable to position at least one of the first and the second sets thereof for bending of the plate. The rolls of at least one of the first set and the second set are disposed for forming the plate on one side and the rolls of the second forming element are disposed for forming on the other side. The first set of rolls of the first forming element is for cooperating with the rolls of the second forming element to bend the plate to form a first of the cross-sectional profiles while the second set of rolls of the first forming element is for cooperating with the rolls of the second forming element to bend the plate to form a second of the cross-sectional profiles.
