Abstract
An edge finishing for a mesh formed by interlacing adjacent wire pickets, each picket formed in a zig-zag manner, the edge finishing comprising two interlinked loops where a first loop is formed from a first picket of the adjacent pickets and a second loop is formed from a second picket of the adjacent pickets, wherein the first loop and the second loop are interlocked together, via first and second loop-ends, at an intersection of the first picket and the second picket.

An edge finishing for a mesh formed by interlacing adjacent wire pickets, each picket formed in a zig-zag manner,
- the edge finishing comprising two interlinked loops where a first loop is formed from a first picket of the adjacent pickets and a second loop is formed from a second picket of the adjacent pickets,
- wherein the first loop and the second loop are interlocked together, via first and second loop-ends, at an intersection of the first picket and the second picket, in a manner that substantially prevents lateral movement of the interlinked loops with respect to one another.
A method of forming an edge for a mesh comprising a plurality of adjacent interlaced zig zag pickets, the edge being formed at the terminal end of adjacent first and second pickets forming a diamond pattern, the method including the steps of:
- bending the zag side of a first picket back over top of the zig side of first picket;
- partially straightening the first picket tail with respect to zag side of the first picket;
- bending the partially straightened first picket tail further around zig side of the second picket until it lies below the zig side of the second picket;
- twisting first picket tail until it has the same orientation as the zig side of the first picket to form first loop;
- bending the zag side of second picket back under the zig side of the second picket;
- partially straightening the second picket tail with respect to the zag side of the second picket;
- bending the partially straightened second picket tail further around zig side of the second picket until it lies above the zig side;
- twisting the second picket tail through the first loop and over the first picket tail until it has the same orientation as the zig side of the second picket to form a second loop;
- twisting both picket tails simultaneously so that the second picket tail meets up with zag side of the second picket, and the first picket tail meets up with zag side of the first picket, to form first and second loop-ends, which interlock the first and second loops.
