    摘要: Die Erfindung betrifft einen für die Frauenhygiene bestimmten Tampon (T) aus einem durch Aufwickeln eines bandförmigen Vliesabschnittes hergestellten zylindrischen Rohling, der durch Beaufschlagen von Preßkraft zu einem Vorformling mit einem Kern mit höherer Verdichtung des Fasermaterials und den Kern Umgebenden Längsrippen mit niedrigerer Verdichtung umgeformt und durch Aufbringen radialer Druckkräfte auf die Längsrippen zum fertigen Tampon (T) endverformt ist. Weiterhin betrifft die Erfindung ein Verfahren und eine Vorrichtung zur Herstellung eines derartigen Tampons (T). Um bei Aufrechterhaltung der Knickfestigkeit die Saugleistung zu erhöhen, ist der Kern durch einen im Querschnitt ringförmigen Bereich (Kr) höchster Verdichtung und einen innerhalb dieses ringförmigen Bereiches (Kr) liegenden zentralen Bereich (Kz) mit mittlerer Verdichtung gebildet.

    摘要: The invention relates to a process and an apparatus for the contiunuous production of absorbent bodies (30) from a web of fibre material (40) which is folded longitudinally several times in a folding station (A) and which is surrounded in a guide tube (86) with a sheathing band (82), the longitudinal edges of which are connected to one another by means of a closing device. The web of fibre material (30) is thereafter fed to a press station (C) which consists of pairs of press and smoothing rollers arranged in close succession and offset at 90° relative to one another. By means of these press rollers, the web of fibre material (130) is rolled down in steps to or below the final cross-section of the absorbent body (30), to form a fleece rod (240). Subsequently, the absorbent bodies (30) are pinched by means of pinching rollers (334, 338) in a severing station (D) and are thereby preformed at the front end and thereafter fed to a forming device, by means of which the front ends of the absorbent bodies (30) are equipped with a round dome and the rear ends of the absorbent bodies (30) with a depression as an insertion aid, when the absorbent body (30) is to be used as a tampon for feminine hygiene. The process and the apparatus allow the high-speed mass production of absorbent bodies which, whilst using less material, make it possible to achieve a higher stability or buckling resistance of the absorbent bodies.

    摘要: The invention is generally accomplished by providing a generally rectangular blank (10) of absorbent material. Adjacent one strip of the rectangular sheet is placed a generally continuous line of adhesive (12). The rectangular blank is then wound and compressed to form a tampon. As the tampon is compressed the adhesive (12) fuses one end of the wound tampon. The blank is provided with a string (14) prior to winding that is also adhesively connected to the tampon. As the tampon expands in the vagina it will open at the insertion end but not expand significantly at the withdrawal end. Therefore this tampon is easier to withdraw but expands readily at the insertion end to prevent leakage. The tampon also resists telescoping during withdrawal.
