Abrégé
(EN)
The present invention provides a tampon pledget having a shaped tip. The present invention further provides a method for forming a tampon pledget having a shaped tip. The method includes a cooling step after the formation of the shaped tip, which results in the minimization and/or prevention of deformation of the shaped pledget tip during the remainder of processing up until the end use by a consumer.
