of an intermediate rotary die assembly that performs into interconnect two or more compound extrusion manifolds it has also been contemplated that a tubular net material may be formed by arranging a series of rotary die assemblies in a circular formation as shown in fig1 or other essentially close ended peripheral profiles again with the inclusion of one or more intermediate rotary die assemblies two or more tubular compound extrusion manifolds may be interconnected in another embodiment of the present invention the rotary die assemblies may comprise primary die assemblies and secondary die assemblies fig1 illustrates secondary dies 10 and 12 operating independent of primary dies 14 and 16 the secondary die assemblies may follow a similar or dissimilar path than that of the primary die assemblies further the secondary dies may travel at a similar or dissimilar rates compared to that of the primary dies the independent secondary dies can be manipulated to acquire a desired characteristic in the resultant net material for example the secondary dies may operate to follow and reinforce selected extruded filaments dispensed from a specific primary die assembly the rate at which the secondary dies travel may also affect how tightly the primary die filaments are interconnected resulting is more or less extensible net material subsequent to formation the net material may optionally be subjected to various chemical and or mechanical post treatments the net material is then collected and packaged in a continuous form such as.
