A method and apparatus for slitting ribbon stock for use in making fins for a heat exchanger. A pair of slitter wheels are mounted to co-act on separate shafts. One of the shafts is driven by a motor and the other shaft is driven therefrom. Notched pulleys mounted on each shaft and a double sided belt connects the pulleys to maintain the slitter teeth and respective wheels in registration during rotation. A phase shifting device is further provided to allow for initial alignment of the slitter teeth relative to the pulleys.
