ABSTRACT:
A packing ring of a composite structure including a packing of expanded graphite and an annular mass of superposed sheets of expanded graphite is produced by a method including the steps of spirally winding a ribbon of expanded graphite into a roll, compression molding the roll into the packing, and incorporating the annular mass into the packing by compression molding within a molding die so that at least one packed part has a higher density than the packing in at least one of the inner and outer peripheral parts of the packing. A seal device has an empty space through which passes a shaft and containing at least one such packing in the empty space to seal between the inner wall of the empty space and the outer peripheral surface of the shaft.
