ABSTRACT:
Method and apparatus for folding first and second end flaps of a sanitary pad, such as a disposable diaper, against the pad. The pad is advanced in one direction with the first flap disposed at the front end of the pad and the second flap disposed at the rear end of the pad. The first flap is allowed to drop into a conveyor gap and the conveyor wipes this flap over a folding element beyond the gap, thus to fold the first flap back against the pad. The pad is then turned end-for-end, desirably by conveying it around a vertical curve, thus to invert the pad and to dispose the second flap at the end of the pad which is now its front end with respect to said one direction. The second flap is now folded back against the pad desirably by advancing it again in said first direction and wiping it against a folding bar over which it is draped in the course of its inversion.
