The invention relates to a folding machine (100) configured to fold a page-type element (1000). The folding machine has a first folding station (2) and a second fence folding station (4). A transmission table (3) is arranged between the two fence folding stations (2, 4), the second folding station (2) is directed relative to the first fence folding station (2) at a 90-degree angle. According to the invention, the transmission table (3) and the second fence folding station (4) are configured to be a structure unit, rotary legs are installed at the area of the downstream of the structure units (3, 4). The rotary legs (13) are configured to perform driving motion to allow the structure units to rotate around the rotation point (D) of the rotary legs (13) so as to simply realize the access of the work area of the folding machine (100) about the regulation and the error elimination.
