发明名称 VERFAHREN ZUR HERSTELLUNG EINES TAMPONS
摘要 A method for coating the tip of a compressed absorbent tampon with a thin film of water-soluble plastic. The uncoated surface of the prefabricated film, such as polyvinyl alcohol, which is to be applied to the tampon is solvent-activated by humidifying the film or by the application thereto of a plasticizing fluid. While the film surface is still activated the film is molded onto the tampon tip by means of a heated tip-conforming die. The result is a thin film of unstressed polyvinyl alcohol intimately bonded to the tampon tip over the entire film-tampon interface by the autogenous adhesive power of the plasticized film.
