Abstract: A cable slitter comprises a support frame and slitting wheel operatively mounted on support frame in position to slit a cable driven longitudinally along the slitting wheel. A rotatable drive wheel is operatively mounted on the support frame for rotation about a substantially horizontal drive axis, in spaced relation from the slitting wheel to together define a substantially longitudinal cable slitting path there between. A slit-adjustment means moves one of the slitting means and the rotatable drive wheel means transversely with respect to the other between a plurality of slitting positions. A drive motor selectively rotates the rotatable drive wheel, to thereby cause a cable in the substantially longitudinal cable slitting path to move forwardly along the substantially longitudinal cable slitting path and engage the slitting wheel, thus causing the cable to be slit.
