发明名称 METHOD AND APPARATUS TO FORM A SPHERICAL END OF AN ELONGATED CYLINDRICAL TUBE.
摘要 A method for shaping a plurality of tampon applicators includes the steps of heating a forming element forming surface; applying a portion of a first tampon applicator to the forming surface; shaping the portion of the first tampon applicator; cooling the forming surface; and removing the portion of the first tampon applicator from the forming surface. The forming element has a high thermal conductivity and a low thermal mass. The step of heating the forming element forming surface includes heating it to a temperature greater than the softening point of the heat-deformable material of the applicator portion. The step of cooling the forming element forming surface includes cooling it to a temperature less than the softening point of the heat-deformable material. The time required to heat and form the portion of the tampon applicator is less than about 90 seconds. These steps are repeated for subsequent tampon applicators. An apparatus useful in a tampon applicator includes a mold body and means to provide at least a portion of the tampon applicator to the mold. The tampon applicator is at least partially formed of a heat-deformable material. The mold body has a forming element, a forming element fluid cavity, means to apply heat to the forming element, and means to provide cooling fluid through the forming element fluid cavity.
