The present invention generally relates to the process of making extruded knit materials in a continuous manner, and more specifically, to an in-line process utilizing a compound extrusion manifold comprising three or more rotary die assemblies for continuously extruding three or more polymeric filaments into a functional knit material suitable for bale wrap, cargo wrap, netted bags, drainage nets, and the like. The in-line process incorporates three or more rotary die assemblies, wherein each rotary die assembly comprises at least one extrusion orifice that is positioned within each of the individual dies so as upon rotation of each of the dies the continuously extruded filaments become intermingled and interlocked.
