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