Patent ID: 8070107

Claim:
A method for making a net structure comprising: (a) selecting a plurality of positioning points on a boundary; (b) providing a plurality of rightwards inclined wires and a plurality of leftwards inclined wires, with a first end of each of the rightwards inclined wires and a first end of a respective one of the leftwards inclined wires fixed to a respective one of the positioning points; (c) intertwining and extending a second end of each of the rightwards inclined wires and a second end of a respective one of the leftwards inclined wires, with the second end of each of the rightwards inclined wires and the second end of a respective one of the leftwards inclined wires being intertwined a plurality of turns to form a twine portion having a beginning fixed to a respective one of the positioning points and an end distant to the boundary, with each of the beginning and the end being an intersection, wherein the twine portion has an even number of turns; (d) extending each of the rightwards inclined wires from the end of the twine portion in a first direction, and extending each of the leftwards inclined wires from the end of the twine portion in a second direction, with each of the rightwards inclined wires intersecting an adjacent one of the leftwards inclined wires at another intersection; (e) extending and intertwining each of the rightwards inclined wires and a respective one of the leftwards inclined wires from one of the intersections away from the boundary, with each of the rightwards inclined wires and a respective one of the leftwards inclined wires being intertwined a plurality of turns to form a twine portion having a beginning adjacent to the boundary and an end distant to the boundary, wherein the twine portion has an even number of turns; and (f) repeating steps (d) and (e) until a net structure with a desired size and hexagonal mesh is obtained.
