  • Patent number: 4791800
    Abstract: A roll forming process is described wherein longitudinal areas of curvature are formed in strip material between longitudinal areas of narrower width, the areas of curvature being bowed downwardly from the center toward the longitudinal flat areas. As the strip material is fed progressively through roll forming stations, the longitudinal areas of curvature are formed into areas of lesser curvature and finally flattened to provide strip material having relative flat areas separated by substantially rectangular ribs. The process is one in which areas of curvature are provided to initially gather strip material for use in forming the sides of one or more ribs with little or no thinning of the strip material.
