1. Continuous plating machine including an anode means, a cathode means and a source of electrical current, for selectively plating a lengthwise portion of a plurality of discrete sheet-like workpieces comprising:

  • a. base frame means;

    b. conveyor means supported from the base frame means and comprising interacting endless tractor tread means having clamping shoes which capture the workpieces therebetween and transport them therealong, with the selected portion of the workpieces to be plated extending out from between the interacting tread means;

    c. backup guide means for selected portions of the interacting tread means to insure a strong clamping action on the workpieces throughout their travel;

    d. plating cell means cooperating with the conveyor means for distributing plating solution onto the exposed portion of the workpieces;

    e. said anode means being in operative relation with the cell means and connected to the current source;

    f. the workpieces being the said cathode means and electrically connected back through the conveyor means to the current source.
