ABSTRACT:
The roll-forming machine includes a series of roll-forming stands for shaping a flat workpiece into a desired configuration, a device for monitoring the positioning of the workpiece at the entry side of the roll-forming machine, and a control unit for sending signals to each roll-forming stand to effect transverse movement of the forming members according to a predetermined roll-forming pattern. The roll-forming stand may have either driven contoured rolls or nondriven forming rollers.
