Cascaded Fin Winding Machine Control and Method Abstract Apparatus and a method for controlling the operation of a fin winding machine. Various motor drives are utilized to regulate the speed of rotation of a heat exchange tube upon which fin is wrapped, to regulate the speed of rotation of forming wheels for bending the fin to the appropriate configuration and to regulate the speed of rotation of slitter wheels for perforating the fin prior to bending. Sensing means are provided for determining the length of the fin strip within various segments along a fin route such that the motor speeds are all adjusted to maintain the desired amount of fin strip. Tension means are provided for maintaining constant tension of the fin strip regardless of the length of the fin strip in the appropriate segment. The various sensing means are cascaded such that a change in speed of one motor may affect a change in speed of another motor.
