<p>A tampon insertion device comprising an elongated tube of spirally wound laminated paper construction provided with a domed insertion end defined by a series of generally hemispherically cupped petals. The petals are formed in a generally triangular configuration through the removal of tube material by appropriate punch and die apparatus. The insertion end of the tube, preferably prior to the defining of the petals in the tube end, is provided with longitudinal scores oriented to locate a single score extending centrally along each of the formed petals. Additionally, multiple circumferential scores are provided about the insertion end of the tube whereby each formed petal will incorporate multiple transversely extending scores. In longitudinally and circumferentially scoring the insertion end, the tube, normally mounted on an inner stabilizing mandrel, is manipulated to introduce the insertion end through an annular die having inwardly directed circumferentially spaced scoring blades corresponding in number to the number of petals to be formed. The mandrel mounted tube next positions the longitudinally scored insertion end adjacent the outer periphery of a roller die with multiple projecting scoring blades for effecting formation of the circumferential scores, either the mandrel supported tube or the roller die being driven with the other freely rotating therewith. The petals are subsequently defined and, utilizing a hemispherically shaped concave female die, formed into the domed configuration.</p> |
