Paper Width 3050 mm Writing Paper Production Line
The writing paper production line is the core of any modern fine paper mill, combining high-speed operation with exceptional sheet quality and printability. This paper manufacturing line 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 production line’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 production line is the integration of vacuum cylinders in the drying section, which enhance heat transfer and significantly reduce steam consumption. The writing paper production line 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 production line minimizes downtime and maximizes output for mills producing offset, copy, and newsprint papers.
