Abstract: Apparatus and associated methodology contemplating a portable sheet metal folding apparatus that folds a sheet metal panel profile into a different predetermined shape, the profile having straight elements joined together by arcs. The apparatus has consecutive roller die sets configured to perform a series of folds on a first element of the profile toward a second element of the profile. Each roller die set has opposing roller dies operably contacting only the first and second elements, not contacting any arc.
