ABSTRACT:
A system and method for impregnating a continuous fiber strand with a heated polymer melt involves the introduction of a polymer melt into a cavity and the routing the fiber strand through the cavity so the fiber is exposed to the polymer melt introduced therein. The strand is scrubbed as it is moved though the cavity so that the polymer melt is pressed against and blended within the fiber strand. The scrubbing action is effected by a rotating scrubber assembly mounted for rotation relative to the cavity about an axis of rotation and includes a plurality of smooth-surfaced pins arranged in a spaced, substantially circular arrangement about the rotation axis and so that the longitudinal axes of the pins are generally parallel to one another. The direction of movement of the pins along the fiber strand corresponds generally with the direction of movement of the strand through the cavity.
