ABSTRACT:
An apparatus for producing a disposable worn article (P), comprises: a folding section (40) comprising a contact member (1) that contacts a web (W) for folding the web (W) in two so that opposite side edges (W1, W2) of the web (W) are in a predetermined positional relationship with respect to each other; a correcting section (1, 2) for correcting the positional relationship between the web (W) being carried to the folding section (40) and the contact member (1); a detecting section (41, 42) for detecting a reference portion of the web (W) to be used as a reference in the folding operation so as to output positional information regarding a position of the detected reference portion; and a controller (3) for controlling the correction of the positional relationship by the correcting section (1, 2) based on the positional information.
