Yarn-wound cartridges
A completely different constructed cartridge has a perforated cylindrical core around which is wound a continuous filament or yarn. With a plastic filament or metal wire, the core may be…

Similar to the edge filter in appearance, in that it has an array of disc-shaped components held on a central core, the stacked disc filter differs because the discs are…
Edge filters involve the use of cartridge elements where the element is composed of a stack of discs or washers of paper, felt, plastic or metal, clamped together in compression.…
The majority of the specific filter media discussed so far in this Section have been porous materials, usually continuous in original format, with an intrinsic porosity consequent upon their method…
A quite different use for metal in making filtration media comes in the structures that are built up from individual bars, rods or wires that may have been processed to…
Expanded metal is made from a metal sheet by a repetitive process that involves first cutting it to form a series of short slits, and then stretching the sheet to…
Perforated metal sheets are more rigid and can be made stronger than woven wire cloths and so they find particular applications in strainers, coarse filters and screens. Perforated metal strainers…
The crimping of the individual wires in a mesh goes a long way towards ensuring the stability of the mesh, and therefore the constancy of the apertures of the mesh,…
The weave of any mesh is usually one of six basic types, but there are also some minor variations. Square mesh (Figure 2.9) has each weft wire passing alternately over…
The weaving of wire is no different, in principle, from the weaving of any other yarn: warp wires are set up along the loom and weft wires across it. The…
