Flexibly-reconfigurable roll forming (FRRF) is a novel sheet metal forming technology by which sheet metal is shaped into a desired curvature using reconfigurable rollers and gaps. FRRF is conducive to producing multi-curvature surfaces by controlling the longitudinal strain distribution. However. it is difficult to predict the forming results since FRRF technology forms a secondary s... https://www.bekindtopets.com/save-big-Winslow-Baskets-2-sizes-best-find/
