Abstract

There is provided a method for post forming an assembled tampon assembly into a curved tampon assembly. Before employing this method, the tampon assembly is completely formed using existing manufacturing methods into a typical straight axial oriented tampon assembly. The tampon assembly is then heated to permit flexing and reorientation of the axis of one or more portions of the tampon assembly. Next, the heated tampon assembly is positioned in a mold cavity of a cold forming mold. The inner surface of one or more portions of the mold cavity has a desired arcuate shape or axial orientation in order to obtain a desired predetermined radius of curvature. Thereafter, the tampon assembly is held in the mold until the various components of the tampon assembly cool down. Finally, the cooled tampon assembly is removed from the mold and is ready to be packaged for distribution.
