CLAIMS

What is claimed is:

1. A process for producing a stabilized product from a pledget, comprising the steps of:
providing a pledget;
providing a transfer member, said transfer member having an expandable portion;
providing a mold, said mold having an interior surface defining an interior cavity;
pushing said pledget into said mold with said transfer member such that said expandable portion is within said interior cavity,
expanding said expandable portion of said transfer member to form a seal with said interior surface of said mold; and
stabilizing said pledget to form a stabilized product preferably while said expandable portion of said transfer member remains expanded.

2. The process according to Claim 1, wherein said expandable portion is a gasket fitted circumferentially around said transfer member.

3. The process according to any of the preceding claims, wherein said transfer member comprises an axial channel extending longitudinally therein and configured to transfer a gas therethrough to said expandable portion.

4. The process according to Claim 3, wherein said axial channel is connected to at least one radial channel extending radially from said axial channel to said expandable portion and configured to transfer a gas from said axial channel in an outward radial direction to said expandable portion.

5. The process according to Claim 3, wherein the step of expanding said expandable portion comprises delivering said gas into said axial channel, thereby creating an outward radial deformation of the expandable member and forming said seal with said interior surface.

6. The process according to any of Claims 1-4, wherein the step of expanding said expandable portion comprises mechanically dilating said expandable portion in an outward radial direction.

7. The process according to any of the preceding claims, wherein the step of stabilizing includes applying a gas to said pledget in said mold, and preferably wherein said seal substantially retains said gas from leaking between said transfer member and said mold during the step of stabilizing.

8. The process according to any of the preceding claims, wherein step of stabilizing includes applying microwave heat to said compressed pledget in said stabilization mold.

9. The process according to any of the preceding claims, further including the step of returning the expandable portion to an unexpanded state.

10. The process according to any of the preceding claims, wherein said stabilized product is a tampon.
