  • Patent number: 4642108
    Abstract: A tampon for feminine hygiene consists of a cylindrically-compressed length of a strip of cottonwool or rayon staple or a combination thereof which is wrapped with an overlap in a fluff-free or fuzz free covering material, said strip being cut into the required lengths together with the covering material perpendicularly to the overlap line, and a recovery thread attached to the length of a strip of cottonwool or rayon staple or a combination thereof. The problem which the invention solves is to prevent fibers from breaking loose from the exposed cut edges. According to the invention, the exposed cut edges are folded onto the surface of the length of a strip of cottonwool or rayon staple or a combination thereof after it has been separated and compression is carried out in such a way that the exposed cut edges are situated inside the tampon.
