Our rimpacks will ensure that you provide extra strength and life to your disc, and they can be manufactured in various diameters to fit any requirement.

The most popular and simplest of all weaves, the stainless plain weave is formed of weft wire warped alternatively above and below creating a wire mesh. The plain is the simplest and the most economical, uses of which include filtration, sifting and for safety equipment. With apertures from 30mm to 0.043mm, the diameter is almost the same for both the warp and the weave. What about the Twill weave?

For heavier requirement, the twill weave is highly recommended. The shute wire is passed above and under two warp wires ensuring that the weave is sturdier as this produces a stronger and more durable wire mesh. The warp and weft have the same diameters thus creating a close diagonal pattern. This type of pattern is commonly utilized for filtration.

Ensuring your machine has the correct end tension will ensure long mesh and machine life. Incorrect tension will cause premature mesh failure and possible screen cracks. End tensioned meshes is mostly found on the screen box bottom decks. With end tension mesh, tension bars are utilized.

Tensioned bars are shaped like a banana, and the curve of the bar must fit into the clamping plate of the mesh. The apex of the curve must face towards the centre of the clamping plate. The bar ends are pitched backwards. The mesh is tensioned using the tensioners either side of the tension bars. By adjusting the end tensioners, the tension bar is straightened to give the correct tension to the mesh.
