    摘要： A tampon for feminine hygiene, having an insertion end, a recovery end, a recovery tape, and a longitudinal axis. The tampon is made of compressed fibrous material and has an outer surface that is at least partially provided with spirally shaped, pressed longitudinal grooves. The grooves define spirally shaped longitudinal ribs. Also disclosed is a method for producing the tampon.

    摘要： An applicator for introducing a therapeutic substance into a body cavity of a subject in need of the therapeutic substance is provided. The applicator has the look and feel of a conventional tampon applicator but delivers a therapeutic substance. Generally, the applicator has a first outer member having a shape suitable for insertion into a body cavity of a mammal and has a dispensing end and a second end distal to the dispensing end. A second inner member is coaxially and slidably housed within the first member such that one end of the second inner member is within the first member. The applicator of the present invention also has at least one aperture located in a side wall of the outer member. The aperture is located on the side wall of the outer member between the dispensing end and the second end of the outer member.

    摘要： A process and apparatus for producing a stabilized product from a pledget, including the steps of providing a pledget and a transfer member, and pushing the compressed pledget into a stabilization mold with the transfer member as the transfer member advances to a loading position. The transfer member is retracted to a stabilizing position. The compressed pledget is stabilized while the compressed pledget is maintained in compression by the transfer member and the stabilization mold to form a stabilized tampon.

    摘要： This invention relates to machines for the manufacture of tampons, the machines having a first set of n pressing dies arranged around a common central axis for pivotal movement together from a separated position for receiving a tampon blank inwardly toward a common axis to a compression position compressing the blank into a shaped tampon and then back to the separated position. Each such first die has generally converging arcuately curved concave and convex surfaces which define therebetween an included angle equal to about 360/n with these curvatures generally mating respectively with the respectively adjacent convex and concave surfaces of other dies on either side to define a narrow arcuately curved gap or slot between the mutually mating surfaces of each adjacent pair of first dies. A cooperating second set of n dies is also arranged for pivotal movement around the common central axis, each second die being disposed for movement toward and from similar separated and compression positions within the arcuately curved gaps or slots between adjacent pairs of first dies after the latter are in their compression position and having opposed concave and convex surfaces mating with the curvatures of the mutually facing surfaces of each pair of first dies which define such gap. Each second die can share a common pivot axis with an adjacent first die.

    摘要： A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.
