Abstract: The present invention provides a method of assembling frameless metal buildings by means of securing together a selected number of roll formed corrugated sheets by the use of cyclically bent corner members roll formed to identically match the roll formed sheets and holding the secured together sheets and bent corner members by mechanical fastening means to provide Total Load Connectivity. The formed frameless buildings have mechanical fasteners connecting adjoining similar corrugated panels to form joints with an engineered joint design that will transfer, without internal load redistribution, loads Fx, Fy, Fz, Mx, My and Mz across the formed joints in the subassemblies and any final on-site assembly so that any desired shaped building may be formed, limited only by the strength of the assembled components and the fastening elements.

Abstract: The present invention provides apparatus, systems, and methods in which a sheet material roll forming system has n sets of rollers configured to simultaneously bend the sheet material in number of different directions and adjustment mechanisms operatively coupled with the sets of rollers and capable of disengaging rollers in a selected roller set from the sheet material, then rotating and/or translating the rollers in the selected roller set and reengaging the rollers with the sheet material passing through the rollers as a function of sensing a plurality of markings on the sheet material and the rollers.

Abstract: Families of products produced by, machines for producing, processes for producing, and a process for designing tooling to bend longitudinally cyclically variable cross-section members from sheet material are provided. The products are for specific applications, and are produced in machines by processes in which a plurality of sets of rollers with mating non-axisymmetric surfaces are specifically designed and mounted in an accurately spaced serial array for bending sheet material passing therethrough a predetermined amount, concurrently in the longitudinal and transverse directions, depending on the shape of the product to be formed and the ductility, strength and stiffness of the sheet material.
