ABSTRACT:
An apparatus for bending and forming sheet metal into U-shaped channel members is comprised of a support block for supporting a blank of sheet metal in a centered position, a pair of rollers that engage in rolling contact against opposite ends of the sheet metal, and an anvil around which the sheet metal blank is formed into the U-shaped channel member. The sheet metal blank is formed over opposite sides of the anvil by the rollers engaging in rolling contact against the opposite ends of the sheet metal blank. As the rollers roll over the opposite ends of the sheet metal blank, they bend and form the sheet metal ends into channel bends having acute interior angles. When the rollers are removed from the sheet metal ends, the resiliency of the sheet metal causes the channel bends to spring back from their acute angle configurations to right angle configurations. The rolling contact of the rollers over the opposite ends of the sheet metal produces the channel bends in the sheet metal without producing tooling marks in the surface of the sheet metal.
