Paper feed of print machine

When the paper printed with high-speed press is decelerated before it is piled up, the vacuum is used to hold paper in deceleration roller.

In the paper feed system of a high-speed printing machine, when the printed paper undergoes deceleration before stacking, a vacuum-based holding mechanism is employed. This system utilizes vacuum suction to securely grip the paper on the deceleration roller, preventing slippage or misalignment during the speed reduction process. The precise control of vacuum pressure ensures smooth paper transfer while maintaining production efficiency and print quality.
