    摘要： A unitary, prefabricated railway car roof and its method of manufacture. Two elongated flat webs of galvanized sheet metal disposed in edge to edge abutting relation, and having a combined width slightly greater than the width of the finished roof, are preferably unwound from rolls and are intermittently moved through a welding station which bonds the two webs together into a single wide sheet. Downstream of the welding station the sheet is fed through dies of a hydraulic stamping press which form transverse corrugations at approximately two foot intervals in the combined sheet to provide stiffening panels extending substantially the full width of the roof, and at the same time to form a gable with the longitudinal weld line being the crest of the gable and defining the longitudinal centerline of the roof. In the finished roof, the stiffening panels cooperate with conventional end and side walls of a railway car to support the roof structure, and the peripheral edge portions of the roof are either welded or riveted to the upper end and side plates of the car.
