<p>A folding machine 100 includes a conveyance roll configured to come into contact with both a first region T1 and the second region T2 being flush with each other; a web guide mechanism 300 configured to cause the first region T1 and the second region T2 to face each other with reference to the folding line so that an angle between the first region T1 and the second region T2 becomes smaller toward downstream; a press mechanism 400 configured to press at least any one of the first region T1 and the second region T2. The press mechanism 400 changes a pressing strength on the web 61, 62 to change at least either a track length (first track length L1) in which one side edge 10A provided on a downstream of a conveyance roll 203 is conveyed or a track length (second track length L2) in which other side edge 20A is conveyed.</p> |
