Tampon, especially for feminine hygiene, and process and apparatus for producing it. |
摘要 |
<p>A digital tampon (20) for feminine hygiene, having a round dome (33) and a recovery tape (24), consists of a blank which is shaped by winding up a length of continuous random fibre web and which is pressed to produce a preform having a fibre core, longitudinal ribs and longitudinal grooves. The longitudinal ribs are subsequently lightly pressed to the final shape of the tampon (20; 28). The preform, before being pressed to the final shape of the tampon (20), is shaped as a result of the separate, but simultaneous radial pressing of directly adjacent sectors of its entire circumferential surface to form a longitudinal groove and a longitudinal rib respectively on each sector of the circumferential surface. The fibre material is pressed radially to a lesser extent in the region of the end (22) provided with the recovery tape (24). The invention also relates to an apparatus for producing the tampon. <IMAGE></p> |
