A method for winding preforms for the manufacture of tampons feeds a material tape. Strips in the form of tapes are separated from this material tape and pushed into a continuously rotating winding drum by at least one drive roller in such a way that the strip is positioned between a winding fork and a guide bar such that when the winding fork moves around the guide bar, the latter pushes a section of the strip into a fork gap of the winding fork and thus enables entrainment. Also, a corresponding device carries out the method.

Reduced-leakage tampon

Tampons including an elongate body and a removal string extending from a removal end of the elongate body. The tampons may include an absorbent material and a spiral flow path that directs menses across the elongate body. The spiral flow path includes at least one complete turn around the longitudinal axis of the elongate body.
