wire mesh 10 comprising a plurality ofinterwoven metal wires 20, as shown inFIG. 1 . Themetal wires 20 are interwoven in a diamond shapedpattern 12. The plurality ofmetal wires 20 includes a cord-shaped cross-section 22 with at least twosharp edges 24 and acircular edge 28, as shown inFIG. 2 . The cord-shaped cross-section has a vertical and horizontal direction, shown as the y-direction and the x-direction inFIG. 2 . The longitudinal direction of themetal wire 20 extends in the z-direction, while thesharp edges 24 extend in the x-direction. Thesharp edges 24 act as a pest deterrent for thewire mesh 10. In one embodiment of the invention, thesharp edges 24 are folded up towards the y-direction to give a near-round metal wire 30, as shown inFIG. 3 . The cord-shaped section 34 of the near-round metal wire 30 is much thinner and lighter than conventional cyclone woven wire for above ground fencing. - The
wire mesh 10 focuses on prevention and protection of the structures where burrowing is unwanted. Thewire mesh 10 is installed by burying thewire mesh 10 just underneath the surface soil and planting grass or other plants over the top. Plants readily root through the diamondshaped pattern 12. Additionally, thewire mesh 10 helps to stabilize the ground surface against erosion. Thewire mesh 10 is not harmful to the animals but is effective in creating a permanent anti-burrowing barrier that is invisible. Themetal wires 20 woven withsharp edges 24 to provide for additional deterrent for excluding pests in any environment. Thewire mesh 10 is significantly lighter than traditional fence and significantly cheaper to produce. - The diamond
shaped pattern 12 may have various dimensions, as appropriate to exclude pests, as shown inFIG. 1 . In one embodiment of the invention, the diamond shape diameter D may be 12-75 mm across. In one embodiment of the invention, the diameter D is 20 mm across. In another embodiment of the invention, the diameter D is 40 mm across. The diameter D of the diamondshaped pattern 12 may be increased or decreased for thewire mesh 10 according to the size of the pest anticipated to burrow in each particular location. For example, if the pest is a rat, the diameter of the diamond shaped pattern would be smaller, such as 20 mm. Alternatively, for larger pests, the diameter of the diamondshaped pattern 12 would be larger, such as 60 mm for nutria and the like. Alternatively, thewire mesh 10 may include alternative dimensions such as a plain weave pattern, twill square weave pattern, double crimp pattern, or intercrimp pattern. - In one embodiment of the invention, the
metal wires 20 are formed by shaving acylindrical metal wire 40 with diameter H, as shown inFIG. 4 . Alternatively, themetal wire 40 may be any suitable metal wire shape, such as rod-shaped, elliptical, etc. As shown inFIG. 5 , themetal wire 40 is shaved in the longitudinal direction with aserrated blade 50 and a lubricant to produce the cord-shaped cross section 22 with thesharp edges 24. The lubricant may be oil. Theserrated blade 50 includesserrated edges 52, as shown inFIG. 6 . The pattern of the serrated edges may be any pattern to sufficiently shave themetal wire 40 and produce thesharp edges 24. The finished shavedmetal wire 20 includes a diameter I that is less than 50% of the beginning diameter H to give the cord-shapedcross section 22 with twosharp edges 24, as shown inFIG. 7 . In one embodiment of the invention, the cross-sectional area is 15% of the original and the weight per length of the wire is 15% of the original weight. The diameter is, for example, H=0.115″ to start and diameter I=0.025″ at finish. The diameter I of the shavedmetal wire 20 may be increased in order to increase tensile strength. Alternatively, the diameter I of theshave metal wire 20 may be decreased to increase the flexibility of thewire mesh 10. - In one embodiment of the invention, the
metal wire 20 is made from stainless steel, as to prevent rusting and corrosion of mesh. However, themetal wire 20 can also be made from bronze, carbon steel, copper, aluminum, metal alloys, and other suitable metals that can be shaved into suitable metal fibers to suit a variety of pest deterring applications. If thewire mesh 10 is made from stainless steel wires, thewire mesh 10 requires no additional coating to protect thewire mesh 10 from rusting or eroding. Typically, wires used for fences require zinc coatings, which are applied by galvanizing after weaving or galvanizing before weaving. Galvanized after weaving (“GAW”) is a process in which wire rod is drawn to the finished gauge, then woven into chain link fabric. The fabric is then pulled through a pot of molten zinc. This process applies 1.2 ounces of zinc coating per square foot of fabric and conforms to ASTM standards. If the wire mesh is made from carbon steel, then galvanizing the metal wire is preferred. Alternatively, nonferrous metals may be preferable in certain environmental conditions. Alternatively, thewire mesh 10 may be coated with a non-corrosive material. - The metal wires can have an average cross sectional dimension similar to round wire between about 6-16 gauge. Gauge is the diameter of round wire, where the higher the gauge number the smaller the wire diameter, each diameter represents a given cross-sectional area. A gauge of 6 corresponds to 0.192 inches diameter (29,000 mils) and 12 gauge corresponds to 0.106 inches diameter (8,800 mils). The preferred embodiment of this invention uses cord-shaped cross section wire of between 2,000-4,000 mils.
- In one embodiment of the invention, the
metal wire 20 includes aflat edge 26 and thecircular edge 28, as shown inFIG. 8A . Alternatively, themetal wire 20 may be re-drawn to fold thesharp edges 22 in anupward angle 80 to form anangled metal wire 82, as shown inFIG. 8B . Wire drawing is a manufacturing process used to reduce or change the cross section of a wire by using a series of draw plates or dies. Various lubricants, such as oils, are employed to facilitate the redrawing of the metal wires. The wire-drawing machines include a means for holding the dies accurately in position and for drawing the wire steadily through the holes. The usual design consists of a table having a bracket standing up to hold the die, and a vertical drum which rotates and by coiling the wire around its surface pulls it through the die, the coil of wire being stored upon another drum or swift which lies behind the die and reels off the wire as fast as required. The wire drum or block is provided with means for rapidly coupling or uncoupling it to its vertical shaft, so that the motion of the wire may be stopped or started instantly. The block is also tapered, so that the coil of wire may be easily slipped off upwards when finished. Before the wire can be attached to the block, a sufficient length of it must be pulled through the die; this is effected by a pair of gripping pincers on the end of a chain which is wound around a revolving drum, so drawing the pincers along, and with them the wire, until enough is through the die to be coiled two or three times on the block, where the end is secured by a small screw clamp or vice ready for the drawing operation. The wire has to be pointed or made smaller in diameter at the end before it can be passed through the die; the pointing is done by hammering, filing, rolling or swaging in dies, which effect a reduction in diameter. When the wire is on the block the latter is set in motion and the wire is drawn steadily through the die. The block rotates evenly and runs true to pull the wire in an even manner to prevent snatching, which will break the wire or weaken the wire. - As shown in
FIG. 8B , theangled metal wire 82 includes theupward angle 80 extending from the longitudinal plane of theflat edge 86. Redrawing themetal wire 20 to form anangled metal wire 82 requirescircular draw plates 88 to form theupward angle 80 of the sharp edges 22. Theangled metal wire 82 may be used to form thewire mesh 10, or may be used in subsequent redrawing steps. - As shown in
FIG. 8C , in another embodiment of the invention, theangled metal wire 82 may be redrawn further to fold thesharp edges 22 in anupward angle 90 to further increase the circular angle of thecircular edge 28 and form angledmetal wire 92.Upward angle 90 extends from the longitudinal plane of theflat edge 96. Redrawing theangled metal wire 82 to formangled metal wire 92 requirescircular draw plate 98 to give the appropriateupward angle 90 of the sharp edges 22. Theangled metal wire 92 may be used to form thewire mesh 10. As shown inFIG. 8D , in another embodiment of the invention, themetal wire 92 may be further redrawn to foldsharp edges 22 in anupward angle 100 and form angledmetal wire 102.Upward angle 100 extends form the longitudinal plane of the edge 106. Redrawing theangled metal wire 102 requires circular draw plate 108 to give the appropriateupward angle 100 of the sharp edges 22. In another embodiment of the invention, as shown inFIG. 8E , theangled metal wire 102 may be further redrawn to foldsharp edges 22 at anangle 32 to form a near-round metal wire 30.Upward angle 30 extends form the longitudinal plane of theedge 36. Redrawing theangled metal wire 102 requirescircular draw plate 38 to give the appropriateupward angle 32 of the sharp edges 22. By redrawing theangled metal wire 102 to the near-round metal wire 30, the tensile strength of the near-round metal wire 30 is significantly increased. Additionally, the near-round metal wire decreases the chances of young children being injured by themetal wire 10 when digging near burrowing sites. The near-round metal wire 30 is not as sharp on one side of thewire mesh 10, but is still effective as a digging deterrent to pests. The near-round metal wire 30 is also effective at preventing pet animals, such as dogs, from digging under fences or into gardens and flower beds, while being safe for pet animals. Finally, the near-round metal wire 30 enables the production of thewire mesh 10 on high speed weaving machinery. - Redrawing
metal wire 20 to the near-round metal wire 30 in a single step frommetal wire 20 may break the wire or snap thesharp edges 24 from themetal wire 20. Thus, redrawing in several steps to the near-round metal wire 30 ensures proper structural integrity of thesharp edges 24 on the near-round wire 30. - The
wire mesh 10 is made by a weaving machine. The weaving machine continually feeds one or two strands of the metal wires into a weaving blade and trough mechanism that bends and weaves the metal wires together. The weaving blade and trough interweave the metal wires by helically winding them to provide a continuous wire mesh, without knots or ties, except possibly at the edges of the finished fabric. After being woven together, the formed continuous links of the wire mesh are cut off at the edges, leaving sharp wire end portions. The wire mesh is finished by knuckling or barbing the, depending on the intended use of the wire mesh. If a knuckled edge is desired, an assembly on the weaving machine bends the metal wire end portions of the wire mesh over one another, forming a knuckle at the edge of the wire mesh. Similarly, if a barbed edge is desired, an assembly on the weaving machine twists the metal wire end portions creating a sharp barb at the edge of thewire mesh 10. Alternatively, the ends of thewire mesh 10 may be integrated into a single metal wire that runs along the border of the wire mesh. The ends of thewire mesh 10 may be woven into the border metal wire. - The
wire mesh 10 may be made in lengths of 12″ to 144″. In one embodiment of the invention, the wire mesh is formed by weaving a series of spirals together. Wire meshes less than 72″ may have both ends knuckled. Wire meshes 72″ and higher, is generally twisted or barbed at one end and knuckled on the other. For longer wire meshes, the wire mesh can be obtained with both ends twisted or barbed.
