An overlaying section (100) has an overlaying drum (110) that holds and conveys a paper sheet (1) after receiving it from a delivery drum (101) and rotates at a peripheral velocity not higher than that of the delivery drum (101). The overlaying section (100) further has upper and lower in-feed rollers (181, 183, ...) that receive the paper sheet (1) from the overlaying drum (110) and convey the received paper sheet (1) to a laminating section (40).
