Lath with Barrier Material

Welded wire lath comprising:

• a mesh formed from a plurality of longitudinal wires and a plurality of transverse wires, said longitudinal wires and said transverse wires being welded at their intersections to form a mesh having a plurality of cells, said mesh having at least two opposed ends, each end being defined by a row of cells sharing at least one common longitudinal wire;
• said transverse wires having indentations at spaced intervals, said indentations coinciding with parallel rows of said intersections and spaced ones of said longitudinal wires being welded to said indentations to form rows of indentations along said spaced longitudinal wires;
• a planar barrier layer of material having a plurality of apertures with webs therebetween, said support material and being interwoven with said mesh, said indentations extending through said apertures and said spaced longitudinal wires spanning portions of said webs to retain said material to said mesh;
• said material having two opposed ends each being defined by a row of end webs extending between a plurality of openings each bounded by a closed curve and being larger in diameter than said apertures;
• and,
• said end webs being folded over and around a common longitudinal wire that is welded to a row of said indentations, and being secured back onto themselves about said common longitudinal wire.

A method of manufacturing a welded wire lath, comprising the steps of:

• providing a mesh of longitudinal and transverse wires welded together at their intersections substantially in a plane;
• forming rows of spaced indentations in said transverse wires, said indentations having portions extending out of said plane;
• after said step of forming rows, providing a planar material having a plurality of apertures being spaced from one another in a pattern corresponding to the locations of said indentations and overlaying said planar material on said mesh such that said portions of said indentations protrude through said apertures;
• after said step of overlaying said planar material, welding a plurality of elongated wires along respective rows of said protruding portions of said indentations to thereby sandwich said planar material between said mesh and said elongated wires.

• providing a mesh of longitudinal and transverse wires welded together at their intersections substantially in a plane;
• forming rows spaced indentations in said transverse wires, said indentations having portions extending out of said plane;
• providing a plurality of sheets of planar material each of said sheets:
• having a plurality of apertures being spaced from one another in a pattern corresponding to the locations of said indentations;
• including interconnected webs of material between said apertures;
• having a row of end webs at least one side of said sheet, said end webs bounded by a closed curve and extending between a row of end openings, said end openings being larger than said apertures;
• having a plurality of holes, each of said holes having a diameter smaller than the diameter of said apertures and sufficiently small that opposed edges of said holes will be in simultaneous contact with its respective indentation to retain said planar support material against transverse displacement when said sheet of planar material is overlaid on said mesh;
• overlaying one of said sheets of planar material on said mesh such that said portions of said indentations protrude through said apertures;
• welding a plurality of elongated wires along respective rows of said protruding portions of said indentations to thereby sandwich said planar material between said mesh and said elongated wires;
• folding and securing each of said end webs over onto itself around a common one of said elongated wires;
• and,
• shearing said mesh into sheets of lath.

• a planar barrier layer of material having a plurality of apertures with webs therebetween, said material being interwoven with said mesh, said indentations extending through said apertures, and said longitudinal retaining wires spanning portions of said webs to retain said material to said mesh;
• and,
• said apertures being circular.
