Abstract

See full text

A tampon is produced rolling up a strip of fiber fleece material to form a cylindrical blank having a cylindrical mantle with mantle sections uniformly distributed over the circumference of the cylindrical blank. Pressing forces are applied to the mantle sections so as to form a preformed blank having a core and longitudinal ribs extending in the longitudinal direction of the preformed blank and distributed adjacent to one another so as to surround the core. The fiber fleece material of the core is compressed more strongly than the fiber fleece material of the longitudinal ribs. The longitudinal ribs are subjected to radial pressure forces for finish-shaping the preformed blank to form the tampon. The core of the tampon has a circular cross-section comprising an annular outer area and a circular central area surrounded by the annular outer area. The fiber fleece material of the circular central area is compressed less than the fiber fleece material of the annular outer area.
