ABSTRACT:
Apparatus for the impregnation of a continuous length of multifilament or multifiber yarns with a molten thermoplastic polymeric resin includes a pair of convex/concave (mating) surfaces for spreading the multifilaments or multifibers apart during their immersion in a bath of the molten resin. The shape, configuration and location of the surfaces facilitates homogeneous impregnation, particularly with highly viscous metls, to produce a uniform and thorough encapsulation of the filaments or fibers.
