Abstract:
1. A folding machine which overlays a first region and a second region of a successively conveyed web for an absorbent article with reference to a folding line parallel with a machine direction along a flow direction of a manufacturing process for the absorbent article, the first region formed between the folding line and one side edge of the web, the second region formed between the folding line and another side edge of the web, the folding machine comprising: a reference roll configured to come into contact with both the first region and the second region being flush with each other and to rotate with conveyance of the web; a web guide mechanism provided downstream of the reference roll in the machine direction, and configured to cause the first region and the second region to face each other with reference to the folding line so that an angle between the first region and the second region becomes smaller toward downstream; and a press mechanism provided downstream of the reference roll in the machine direction, and configured to press at least any one of the first region and the second region, wherein the press mechanism includes a variable roll configured to come into contact with at least one of the first region and the second region, and a position changer configured to change a position of the variable roll, the variable roll includes a central axis along a cross direction crossing the machine direction in a plan view of the web, the position changer is configured to move the central axis of the variable roll, the position changer includes: the press mechanism changes a pressing strength on the web to change at least any one of lengths of tracks in which the one side edge and the other side edge are respectively conveyed downstream of the reference roll in the machine direction.
