摘要： An improved apparatus and method compresses a cylindrical blank into a tampon which is dimensionally stable and which is provided with a domed insertion end. A cylindrical blank is radially compressed and then introduced into a cylindrical axial compression chamber. The blank is then subjected to an extreme axial overcompression. The closed insertion end of the compression chamber has a bore formed therethrough. The bore is generally coaxial and is adapted to accept a reciprocating ejection ram having a ram surface facing into the chamber. When the ram is seated in the first position, the ram surface and the insertion end wall of the compression chamber together form a smooth doming surface. The bore periphery is of a smaller diameter than the chamber and hence radially spaced from the side walls of the chamber, and the ram has sufficient clearance to move through the chamber and eject the tampon without interference from the walls of the chamber.

摘要翻译： 改进的装置和方法将圆柱形坯料压缩成尺寸稳定的棉塞，并且设置有圆顶插入端。 圆柱形坯料被径向压缩，然后引入圆柱形轴向压缩室。 然后坯料经受极端的轴向过压。 压缩室的封闭插入端具有通过其形成的孔。 孔通常是同轴的，并且适于接受具有面向腔室的冲头表面的往复式排出冲头。 当冲头位于第一位置时，压头室的压头表面和插入端壁一起形成平滑的圆顶表面。 孔周边具有比腔室更小的直径，并且因此与腔室的侧壁径向间隔开，并且冲头具有足够的间隙以移动通过腔室并且弹出卫生棉条而不受室的壁的干扰。
