发明名称 PERFEZIONAMENTO NEI PROCEDIMENTI PER LA FABBRICAZIONE DI TAMPONE CATAMENIALI
摘要 A method is provided for manufacturing a dimensionally stable compressed article such as an absorbent catamenial tampon comprising compressed cellulosic fibers. The method comprises the steps of first radially compressing a cylindrical blank to form a radially compressed blank having a length in excess of the desired finished length; then axially compressing the blank in a heated chamber to a length less than the desired finished length; then allowing the blank to expand to the desired finished length; and then maintaining the blank at this length while still in the heated chamber until the blank obtains the desired stability.
