Abstract
A catamenial tampon is assembled from a cylindrical pledget of compressible absorbent material, such as rayon or cotton, and a rectangular blank of foraminous sheet material. The central portion of the blank is placed adjacent one end face of the pledget, and the pledget is then pushed axially through a tubular die with its one end face leading so that the annular portion of the blank around the central portion is draped around the entire peripheral surface of the pledget and the converted blank forms a cup with an annular rim extending beyond the other end face of the pledget. The rim is then folded over the other end face of the pledget, and the resulting assembly is provided with a removal cord subsequent to simultaneous reduction of the diameters of the cup and pledget to complete the making of a tampon which is ready for use or for insertion into the tube of an applicator.
