This invention provides a degassing mechanism for folding pages in commercial printing presses. The degassing blade of this mechanism is mounted on a rotating wheel in a serrated shape. The degassing blade is a ring-shaped cutter with serrated edges, which leaves a series of air holes on the paper as it passes through. The rotating wheel is located in front of the paper feed roller in the conveying direction, placing it diagonally above the roller. This allows the degassing blade to apply positive pressure to the paper as the roller moves forward, preventing slippage and ensuring paper quality. The degassing ring groove ensures the depth to which the degassing blade cuts the paper, guaranteeing that each tooth leaves an air hole at the fold line. This achieves ideal degassing during folding, preventing air pockets at the fold line and significantly improving the flatness of the folded paper, thus enhancing the overall quality of the final paper processing.
