Writing Paper Machine for Fine Paper Mills
The writing paper machine is the core of any modern fine paper mill, combining high-speed operation with exceptional sheet quality. This writing paper machine utilizes a fourdrinier section with a top wire former that allows improved formation and retention, resulting in optimal fiber distribution and bonding strength. The writing paper machine’s press section employs a vacuum suction transfer roll followed by three hydraulically loaded nips, achieving high dryness without crushing the sheet.
A key advantage of this writing paper machine is the integration of vacuum cylinders in the drying section, which enhance heat transfer and significantly reduce steam consumption. The writing paper machine also includes a film transfer sizing machine with an air diverter, applying a precise amount of starch to both sides for improved surface strength and printability. A two-roll soft calender at the dry end ensures superior smoothness and gloss for high-quality printing applications. With a user-friendly design featuring hydraulic loading, electric tensioning devices, and a rope-less tail threading system, this writing paper machine minimizes downtime and maximizes output for mills producing offset, copy, and newsprint papers.
