Traditional sizing methods may result in uneven coatings, affecting the quality of the final product. To overcome these challenges, film transfer sizing technology has emerged, which provides a more consistent and controllable coating effect by uniformly transferring the sizing film to the surface of the paper.

A hot air drying port is formed on one side of the second mounting plate, and a plurality of heating wires are mounted inside the hot air drying port. Through the rotation and extrusion of the sizing roller and the pressure sizing roller for preliminary uniform treatment, then the paper will be scraped by three consecutive scraping cylinders, and the excess sizing material caused by uneven sizing on the paper will be scraped off.
