The world of wire mesh unfolds as a dynamic and versatile landscape, offering a spectrum of options to cater to the diverse needs of various industries. From the stalwart stainless steel wire mesh to the lightweight and cost-effective aluminum counterparts, each type brings unique attributes and applications to the forefront. The intricacies of sintered wire mesh, with its molecular-level bonding and laminated layers, add a layer of sophistication that enhances durability and adaptability.
To facilitate the centuries-old weaving process, wire mesh suppliers must employ specialized weaving looms designed to work with metallic wires. These looms consist of seven components: a warp beam, warp wires, heddle frames, weft wires, a rapier band, a reed, and a front take-up mechanism.
The warp beam is a cylindrical beam that is used to wind the warp wire after the volume and length of the wires are calculated based on the specifications of the mesh.
Warp wires are the wires that run vertically and are threaded through the entire loom.
The heddle frames are holsters that are used to organize and separate the warp wires. Looms set up to produce a square mesh may have two sets of heddle frames, whereas more complex filter cloth weaves may have more.
Weft wires are the wires the run horizontally and are typically fed by a separate spool of wire.
The rapier band system is responsible for threading the weft wire through the sets of warp wires between heddle frame movements.
The reed is one of the most essential elements of a weaving loom as it is used to position the warp wires they will be woven in and drive the weft wires into their exact potion.
The front take-up mechanism rolls the woven mesh once it is fully woven.
To initiate the weaving process, a loom operator will attach and arrange the individual wires on the warp according to their position in the weave. To prevent entanglement, these wires are housed in a wire housing unit known as a creel.
Once attached, the warp beam is wound, allowing the proper length of wire to be wrapped around the beam.
Each wire wound on the warp beam is threaded through its own heddle in a specific heddle frame then carefully threaded through the reed openings based on their order in the weave. At this point, the warp beam, heddle frame assembly are transferred to the weaving hall, and the remainder of the loom is assembled.
NOTE: A great deal of attention to detail must be applied when threading the wire through the heddle frames and reed, as this process control how accurate the mesh specifications are.
Once the loom is fully assembled and the wires are properly threaded, the weaving process can begin.
When first initializing the weaving loom, the warp beam unwinds slightly to feed a small increment of wires. At the same time, the front take-up mechanism winds the same increment of wires to maintain the required tension to produce high-quality mesh.
Once these movements are made in conjunction, the heddle frames shift to separate the wires. In a two-heddle frame system, the first heddle frame lifts one half of the wires, and the second heddle frame drives the other half of wires down.
While the two sets of wires are separated, a weft wire, typically fed from a wire spool that is separated from the creel and placed next to the loom, is shot between the wires by the rapier band. The rapier band then moves back to its resting position.
It's at this point that the reed propels the weft wire to its final position, creating the precise cross-sections that wire mesh is known for. Once the weft wire is positioned, the reed returns to its resting position.
This marks the completion of the first interval.
To continue the weaving process, the warp beam and front take-up mechanism make the same slight, rotating movement to begin another interval. At the same time, the heddle frames will switch potion, wedging the previous weft wire as the two sets of wires are separated in the opposite direction.
These joint movements repeatedly continue until the desired length and mesh specification is woven.
