WOVEN SCREEN TYPES: W-harp / long slot
W-HARPS are screens made from crimped, round cross-section longitudinal wires that run perpendicular to the screening plane and are interwoven with groups of three cross wires at certain intervals. The length of the slots is generally between 100 and 150 mm.
The consistent spacing of the cross wires ensures greater stability and better constancy of the mesh aperture than in the case of G-harps.
Screen tensioning: Longitudinally tensioned
