ABSTRACT:
A barrier-type metal wire fabric which is substantially free of transverse passages while providing desired travel path flexibility is disclosed along with methods and means for its manufacture. Shaped wire with at least two diametrically opposed planar surfaces is helically wound with a planar surface confronting the working surface of the winding mandrel. Left-hand wound and right-hand wound spirals are assembled with individual loop portions of each being nested within the loops of its next adjacent oppositely-wound spiral. A connector rod inserted within longitudinally overlapping internal loop portions of such spirals provides for pivotal relative movement between adjacent spirals and desired travel path flexibility while the dimensional relationships and assembly taught substantially eliminate non-rotational relative movement between metal wire elements of the fabric.
