Roots blowers can be used in the printing industry:

In the printing industry, the suction and pressure of the Roots blower are used to separate the paper that has been accumulated for too long to avoid mutual

 adhesion, and can be automatically collected and transmitted at high speed. The suction transmitted by the blower can also be used to absorb the paper just

 processed from the printing press on the roller to delay its travel speed in the shipping accumulation. In the packaging machinery industry, the suction function

 of the blower is mainly used. In the engineering of packaging products, the vacuum adsorption technology of blowers is used to fix products, assist in transportation

 and other functions.
