ABSTRACT:
In an apparatus for rolling metal ribbon stock into convoluted fin strip for use in heat exchangers, an uncoiler apparatus comprising a base, a pair of coil supports for supporting a pair of coils of sheet metal ribbon stock. The coil supports are mounted on a plate which is rotatable about a vertical axis so that when the plate is rotated, one coil support is moved into driving engagement with the motor and the other coil support is moved out of driving engagement with the motor. A control system interconnects the drive of the motor on the uncoiler apparatus with the drive of the remainder of the corrugated fin rolling machine for positively driving the uncoiler as a function of machine speed.
