2640mm Fourdrinier Paper Manufacturing Machine
The paper manufacturing machine is optimized for producing writing paper and newsprint with exceptional formation and surface properties. Its air‑cushion headbox provides stable total pressure and level control, ensuring uniform cross‑direction basis weight with a variation of only ±2 percent. The forming section uses a single long wire with a top wire former to enhance sheet symmetry and retention. The press section incorporates a vacuum suction transfer roll followed by a four‑roll three‑nip compound press and a gloss press, achieving press exit dryness of 44 percent with line pressures up to 250 kN/m.
