Abstract
A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter.
