Ensuring your machine has the correct end tension will ensure a long mesh and machine life. Incorrect tension will cause premature mesh failure and possible screen cracks.
End tensioned meshes are usually found on the screen box bottom decks. With end tension meshes, tension bars (or banana bars) are used.
Tension bars are shaped like a banana. 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 bar. By adjusting the end tensioners, the tension bar is straightened to provide the correct tension to the mesh.
CAUSES / TIPS ON MESH FAILURES
Mesh broken in multiple areas or along the clamp (shiny worn steel surfaces will be found on the underside of the mesh) loose tension bar.
