Paper Making Machine Scraper

In the vast and sophisticated papermaking machine, there is a seemingly simple yet crucial component—the scraper/ doctor blade. The scraper is a thin, flexible steel sheet. Its core functions can be summarized as follows:

 

Functions of the Paper Making Machine Scraper

 

1. Ensure a smooth and flat paper surface: It promptly removes fine fibers, sizing agents, or impurities that may adhere to the drying cylinder surface.

2. Control paper thickness and uniformity: The paper making machine scraper ensures the uniformity of heat and pressure applied to the paper during the drying process, thus helping to maintain a consistent thickness (grammage) of the finished paper.

3. Improve the physical properties of the paper: By slightly compacting the paper fibers, it enhances the paper’s density and surface strength, making it less prone to linting or dusting during subsequent printing or processing.

 

In conclusion, the scraper plays a vital role in the papermaking machine. If you want to know more, please feel free to contact us. Email address: leizhanchina@gmail.com.
