A sheet-speed reduction mechanism for a fan wheel including: fan wheels 31 that hold, between fan blades 31a thereof, a signature W transported from a printing press thereto, and that rotates with the held signature W; a stopper portion 32a that restricts the front end of the signature W held between the fan blades 31a, and that then discharges the signature W from the inside of the fan wheels 31; and speed-reduction guides 33 that presses a surface of the signature W advancing between the fan blades 31a before the front end of the signature W comes into contact with the stopper portion 32a, so as to reduce the advancing speed of the signature W. |
