ABSTRACT:
Relatively narrow width, relatively fragile ribbon is payed off of a traverse wound, relatively much larger width core and is guided over a bar, which has a concave, smoothly curved surface, so as to minimize back and forth, side to side wandering of the ribbon as the ribbon is being payed off the core. The curved surface of the bar includes a number of roller bearings that are mounted side by side on the bar and that serve to minimize friction as the ribbon is guided and passed over the curved surface of the bar.
