A first pair of fiber band guides is located adjacent to and upstream of the first pair of rollers relative to the direction of travel of the fiber band, a second pair of fiber band guides is located intermediate the second and third pairs of rollers and a pair of coaxially spaced apart annular ring slots are provided in the outer surface of one of the first pair of rollers with the first and second pairs of guides being aligned with the ring slots for maintaining the fiber bands in alignment with the ring slots.
