Abstract

933,543. Making box girders. J. ROSANES. July 15, 1960 [May 31, 1960], No. 24644/60. Classes 83 (2) and 83 (4). A method of forming a hollow, box-type tapering beam from sheet metal comprises the steps of providing an elongated blank of sheet metal of the required thickness, marking thereon the positions of the longitudinal edges of the tapering beam to be produced, cutting if necessary along the outer edge markings, bending along the remaining markings until the outer longitudinal edges of the blank abut or are closely adjacent each other and finally connecting the outer edges by welding to form one longitudinal edge of the beam. The blank shown at Fig. 2 would have the bends made in the following order, first along line DM, second along line BF, and finally along line AE. Due to the inherent springiness of the metal, the edges abut when the folded blank is drawn off the bending tool.
