Abstract (en)
[origin: WO9950019A1] Methods of making a wedgewire pressure screen (10) and pressure screens made thereby. Spacers (14) are integrally formed on wedgewires (12) with the wedgewires grouped side by side in a flat arrangement. The wedgewires (12) are then flexibly secured to each other by a flexible bonding means such as a thin weld bead (20). The spacers (14) are used instead of discrete shims and abut against neighboring wedgewires (12) to thereby improve the dimensional accuracy of the slots (48) formed between adjacent wedgewires (12). The flexible panel is formed into a cylindrical shape via bending. End and support rings (84) are secured to the cylinder to form a cylinder screen basket.
