A ROLLING MILL MACHINE FOR LONGITUDINAL BENDING OF PLATE A rolling mill machine is for longitudinal bending of plate to provide a cross-sectional profile. The machine includes elements for advancing the plate in a longitudinal direction through a plurality of longitudinally spaced shaping stations. Each of the shaping stations extends in a generally transverse direction relatives to the longitudinal direction and includes an upper row of forming rolls and a lower row of forming rolls which are disposed in spaced relationship along the transverse direction for respectively bending the plate advancing therebetween to form the profile. Some of the shaping stations include centrally located forming rolls being longitudinally displaced forwardly of the other of forming rolls in the upper and lower rows for initially bending the plate by these centrally located forming rolls. Additionally, the forming rolls respectively combine with corresponding other forming rolls to form generally converging longitudinal rows of the forming rolls. The machine may include each of the forming rolls being mounted for rotation about a shaft which extends perpendicular to the longitudinal rows of each of the forming rolls. |
