1. A roll forming machine, the roll forming machine comprising:
a first frame;
a first turret assembly having a first turret rotational axis, the first turret assembly rotatable about the first turret rotational axis with respect to the first frame;
a first set of two or more pairs of forming rollers mounted to the first turret assembly, the two or more pairs of forming rollers of the first set sequentially arranged extending along the first turret rotational axis, the two or more pairs of forming rollers of the first set spaced longitudinally from one another along the first turret rotational axis, the forming rollers of the first set laterally spaced outwardly from the first turret rotational axis in a first lateral direction, the forming rollers of each pair in the first set arranged to complementarily cooperate with one another to perform a respective rolling forming operation, the two or more pairs of forming rollers of the first set arranged along the first turret rotational axis to successively perform respective roll forming operations;
at least a second set of two or more pairs of forming rollers mounted to the first turret assembly, the two or more pairs of forming rollers of the second set sequentially arranged extending along the first turret rotational axis, the two or more pairs of forming rollers of the second set spaced longitudinally from one another along the first turret rotational axis, the forming rollers of the second set laterally spaced outwardly from the first turret rotational axis in a second lateral direction, the second lateral direction different from the first lateral direction, the forming rollers of each pair in the second set arranged to complementarily cooperate with one another to perform a respective rolling forming operation, the two or more pairs of forming rollers of the second set arranged along the first turret rotational axis to successively perform respective roll forming operations;
a drive motor; and
a transmission that drivingly couples the drive motor selectively to the forming rollers of the first or at least the second set of one or more pairs of forming rollers, the transmission accessible from an exterior of the first turret assembly without dismantling of the first turret assembly,
wherein the forming rollers of the first set of two or more pairs of forming rollers and the forming rollers of at least the second set of two or more pairs of forming rollers are mounted to rotate in unison with the first turret assembly about the first turret rotational axis.
