Looped Wire Screens
Wedge Wire is made from round wire which is first looped at regularly pitched intervals and then pressed into a deep wedge shaped section. The loops themselves are pressed so as to produce at each side accurately sized spacing shoulders which butt together when the wires are assembled. The width of the slot apertures in the finished panel is determined by the difference between the width of the top face of the wedge profile and the width over the spacing shoulders. The individual Wedge Wires are built into panels by feeding cross rods of suitable diameter through the loops of the wires. The whole is then clamped together and made secure. The finished sieve is therefore a grille made up of cross rods supporting profiled wires with loops.
