  • Publication number: 20130175312
    Abstract: An apparatus for manufacturing absorbent articles includes: a detecting section detecting an edge position of a continuous sheet in the width direction when the detecting section is stopped at a stop position, a meandering correcting section correcting meandering of the continuous sheet, a motor moving the detecting section in the width direction, and a controller controlling the motor based on a movement signal related to movement of the detecting section. The controller has a value corresponding to a distance from a reference position to each stop position, moves the detecting section to each stop position based on the corresponding value and the movement signal. The controller detects that the detecting section reaches the reference position based on a current of the motor. The reference position is a limit position for physical movement in the width direction of the detecting section, and is at or outside the outermost stop position.
