Today, as the requirements on the quality of printing become higher and higher, and the requirements on the surface finish of the paper become higher, the high-speed paper slitting used at present destroys the surface finish of the paper when the paper is overlapped.

As shown in figure 1, a high-speed belt transmission shaft 4 transmits a high-speed conveying belt 1, paper 2 on the high-speed belt runs on the high-speed conveying belt 1 in a single-sheet high-speed mode, and a high-speed paper pressing wheel 3 presses the paper 2 on the high-speed belt to run. The high-speed belt transmission shaft 4 and the low-speed belt transmission shaft 6 have a height difference so that the sheets overlap. When the paper 2 on the high-speed belt runs onto the speed-reducing paper pressing wheel 9 on the low-speed belt, the paper is quickly reduced and falls on the low-speed conveyer belt 7, then the paper runs at the speed of the low-speed conveyer belt 7, and the paper 2 on the high-speed belt is sucked down through the paper board 5 by air suction so that the paper 2 on the second high-speed belt passes through, and the paper is overlapped and runs together by the action.
