Abstract
Abstract A roll-forming machine includes a plurality of roll-stands for moving material along a predetermined path and a plurality of die-stands for progressively transforming the material from an initial configuration to a desired configuration. The die-stands are mounted on and positioned by an elongate, rigid spine which permits conversion of the machine from one roll-forming configuration to another by replacing the spine and the diestands mounted thereon with a different spine-die-stand assembly. Each die-stand includes at least one roller supporting the material for movement along the path, a toroidal roller engaging the material along the line of a desired bend, at least one primary bend roller engaging the material beyond the toroidal roller and positioned to bend the material toward the toroidal roller, and a guide roller engaging the edge of the material to absorb forces caused by the formation of bends in the material. These rollers are selectively positionable as a group to change the roll-forming configuration of the roll-forming machine. Also, one of the primary bend rollers and the guide roller may be selectively positionable relative to the toroidal roller and the support rollers to further change the roll-forming configuration of the roll-forming machine.
