Abstract

Packing which comprises a ring with reduced height compared with its diameter, which consists of a band of graphite and of a perforated metallic sheet or mesh. The band and the sheet are rolled together and are compacted by means of pressure, the graphite being embedded in the perforations of the metallic sheet, giving rise to irregular circumferential deformations in the band and in the metallic sheet.
