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 die-stands mounted thereon with a different spine/die-stand assembly.
The roll-stands each include at least a pair of lower rollers which are selectively positionable transversely with respect to the predetermined path to accommodate materials of various widths in the roll-forming machine. In certain embodiments of the invention each roll-stand further includes a pair of upper rollers which are floatingly supported to accommodate materials of various thicknesses in the roll-forming machine and which are selectively positionable transversely with respect to the predetermined path and in alignment with the lower rollers. In other embodiments idler rollers are mounted on the spine for cooperation with the lower rollers to drive material through the roll-forming machines. The roll-stands may be actuated either by means of a common drive system or by means of individual drive motors.
