<p>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.</p> |
