Abstract
A method of and apparatus for the bending of metal-sheet section comprises a bending saddle engaging the section at two spaced-apart points and a bending anvil or support engaging the workpiece at two other points disposed outwardly of the first two points. The bending saddle is pressed toward the anvil so that the sheet bends substantially uniformly between the two bearing points of the saddle and the two support points of the anvil with substantially equal bending force components equidistant from the center between the support points. After each bending stroke of the saddle, the workpiece is advanced by an increment less than the length of the uniformly bent section between the two saddle bearing points.
