Abstract: An apparatus for bending sheet metal comprises a housing, a first shaft and a second shaft mounted in the housing, a motor, a first gear mounted on the first shaft, and a second gear mounted on the second shaft. The motor rotates both the first gear and the second gear. The first gear comprises a first plurality of components and the second gear comprises a second plurality of components. The first gear and the second gear are capable of engaging sheet metal passed between the gears while they are moving. The first and second plurality of components are capable of being configured to change a bend radius, a wavelength of waves formed in the sheet metal, and a distance between the first shaft and the second shaft can be adjusted to change an amplitude of waves formed in the sheet metal engaged by the first and second gears.
