2640mm Width Cultural Paper Machine
The cultural paper machine is specifically designed to manufacture premium writing paper and newsprint with outstanding surface properties and printability. This paper making machine combines a heated hard roll with a controlled crown soft roll, delivering uniform nip pressure and precise temperature control across the entire sheet width. The hard roll maintains a surface temperature of up to 180°C with a variation of less than one degree Celsius, ensuring consistent gloss and smoothness.
The soft roll with a high‑quality polyurethane cover provides gentle pressing, preserving sheet bulk while eliminating two‑sidedness. The paper production equipment achieves excellent cross‑direction profiles, reducing waste and improving runnability in downstream converting. Advanced hydraulic loading with imported components allows fine adjustment of line pressure from 20 to 160 kN/m, adapting to different basis weights and furnish compositions. This paper industry machinery operates smoothly at 450‑500 m/min with a dynamic balance speed of 600 m/min, guaranteeing vibration‑free performance. The robust design and precise engineering make it an ideal choice for modern paper processing lines targeting high‑grade cultural paper markets.
