Abstract
A roll forming machine capable of forming the corrugated metal web of a sinusoidal structural member is provided. The preferred embodiment includes a material feeding means (12), a material guiding means (20), and at least two forming cylinders (14, 16). The material feeding means receives a sheet of material (18), and is in material communication with the material guiding means (20). The material guiding means receives the sheet of material, guiding the sheet of material (18) into the forming cylinders (14, 16) and preventing significant movement or buckling of the sheet of material. The forming cylinders are a set of at least two substantially aligned and parallel cylinders, having a separation between sufficient to receive the sheet of material. The forming cylinders (14, 16) can alternately orbit one around the other, one forming cylinder axis being held substantially stationary while the other forming cylinder orbits the stationary cylinder, bending the sheet of material and forming the desired web geometry.
