Paper sizing is the process of applying sizing agents to paper fibers to control the paper’s interaction with liquids, particularly water and ink. This treatment fundamentally changes the paper’s surface characteristics, affecting how it performs in various applications. Raytron sizing machines can be customized to suit different machine layouts and space constraints. They consist of a rubber-coated pressure roller and a hard-faced roller, forming a pressure roller groove. The paper web passes through this groove, and the sizing agent is stored in a pool within the groove. As the paper passes through, it absorbs the sizing agent, achieving uniform sizing across the entire width of the paper.

 

Sizing machines typically occupy a key position in paper production lines: Post-drying stage: Paper enters the sizing machine with the appropriate moisture content; Post-sizing drying: An additional drying stage removes the moisture added during the sizing process; Quality control integration: Connected to an online quality measurement system. Paper mills using Razor sizing machines report significant improvements in paper quality, with uniform sizing across the entire paper web and enhanced smoothness, strength, and printability.
