Abstract

A manufacturing assembly and method produce a wire mesh including a plurality of longitudinal members and a monolithic transverse member secured to the plurality of longitudinal members. The monolithic transverse member includes a plurality of transverse portions that define a first cross-sectional shape, and further includes a plurality of longitudinal portions that define a second cross-sectional shape different than the first cross-sectional shape.

Claims (22)

1. A lath comprising:

a plurality of longitudinal members arranged such that each of the plurality of longitudinal members is elongate along a longitudinal direction, each of the plurality of longitudinal members spaced apart from adjacent ones of the plurality of longitudinal members along a transverse direction that is perpendicular to the longitudinal direction, the plurality of longitudinal members including an outermost pair of longitudinal members; and

a monolithic transverse member including a plurality of transverse portions that are each elongate along the transverse direction, and further including a plurality of longitudinal portions each coupling a pair of adjacent ones of the plurality of transverse portions, the plurality of transverse portions defining a first cross-sectional shape within a plane perpendicular to the transverse direction, the plurality of longitudinal portions defining a second cross-sectional shape within a plane perpendicular to the longitudinal direction, and the first cross-sectional shape being different than the second cross-sectional shape,

wherein the monolithic transverse member is secured to the plurality of longitudinal members such that the plurality of longitudinal portions are positioned outside an area defined between the outermost pair of longitudinal members.

2. The lath of claim 1 wherein the plurality of longitudinal portions are each elongate along the longitudinal direction.

3. The lath of claim 1 wherein the monolithic transverse member is furred.

4. The lath of claim 1 wherein the monolithic transverse member is a first monolithic transverse member, the plurality of transverse portions is a first plurality of transverse portions, and the plurality of longitudinal portions is a second plurality of longitudinal portions, the lath further comprising:

a second monolithic transverse member secured to the plurality of longitudinal members, the second monolithic transverse member including a second plurality of transverse portions that are elongate along the transverse direction, and further including a second plurality of longitudinal portions each coupling a pair of adjacent ones of the second plurality of transverse portions, the second plurality of transverse portions defining a third cross-sectional shape within a plane perpendicular to the transverse direction, the second plurality of longitudinal portions defining a fourth cross-sectional shape within a plane perpendicular to the longitudinal direction, and the third cross-sectional shape being different than the fourth cross-sectional shape.

5. The lath of claim 4 wherein the second monolithic transverse member is secured to the plurality of longitudinal members such that the second plurality of longitudinal portions are positioned outside an area defined between the outermost pair of longitudinal members.

6. The lath of claim 4 wherein the second monolithic transverse member is secured to the plurality of longitudinal members such that the second plurality of longitudinal portions are positioned inside an area defined between the outermost pair of longitudinal members.

7. The lath of claim 4 wherein the first monolithic transverse member and the second monolithic transverse member are secured to the plurality of longitudinal members such that the first plurality of transverse portions and the second plurality of transverse portions alternate along the longitudinal direction.

8. The lath of claim 4 wherein the first cross-sectional shape is the same as the third cross-sectional shape.

9. The lath of claim 4 wherein the first cross-sectional shape and the third cross-sectional shape are defined within the same plane.

10. The lath of claim 4 wherein the second cross-sectional shape is the same as the fourth cross-sectional shape.

11. The lath of claim 4 wherein the first monolithic transverse member is furred, the second monolithic transverse member is furred, or both the first and second monolithic transverse members are furred.

12. The lath of claim 4 wherein the first monolithic transverse member establishes a first stroke length measured along one of the first plurality of transverse portions from one of the first plurality of longitudinal portions to another of the first plurality of longitudinal portions, the second monolithic transverse member establishes a second stroke length measured along one of the second plurality of transverse portions from one of the second plurality of longitudinal portions to another of the second plurality of longitudinal portions, and the first stroke length is equal to the second stroke length.

13. The lath of claim 4 , further comprising:

a third monolithic transverse member secured to the plurality of longitudinal members, the third monolithic transverse member including a third plurality of transverse portions that are elongate along the transverse direction, and further including a third plurality of longitudinal portions each coupling a pair of adjacent ones of the third plurality of transverse portions, the third plurality of transverse portions defining a fifth cross-sectional shape within a plane perpendicular to the transverse direction, the third plurality of longitudinal portions defining a sixth cross-sectional shape within a plane perpendicular to the longitudinal direction, and the fifth cross-sectional shape being different than the sixth cross-sectional shape.

14. The lath of claim 13 wherein the first monolithic transverse member, the second monolithic transverse member, and the third monolithic transverse member are secured to the plurality of longitudinal members such that:

each of the first plurality of transverse portions is adjacent one of the second plurality of transverse portions and is adjacent one of the third plurality of transverse portions;

each of the second plurality of transverse portions is adjacent one of the first plurality of transverse portions and is adjacent one of the third plurality of transverse portions; and

each of the third plurality of transverse portions is adjacent one of the first plurality of transverse portions and is adjacent one of the second plurality of transverse portions.
