PCT No. PCT/GB93/01480 Sec. 371 Date Dec. 7, 1994 Sec. 102(e) Date Dec. 7, 1994 PCT Filed Jul. 14, 1993 PCT Pub. No. WO94/03742 PCT Pub. Date Feb. 17, 1994An embossed sheet coated at least partially with expanded graphite and suitable for use as a gasket or as a component layer of a gasket is manufactured by positioning a planar metallic sheet between an upper embossing die and a lower embossing die with a layer of particles of expanded graphite between one of said dies and a surface of the sheet. One of the dies has a protuberance to emboss a ridge into the sheet while the other die has a recess to receive the ridge. The method also comprises pressing the dies together to cause the particles to coalesce and form a coating attached to the sheet while simultaneously embossing said ridge into the sheet. |
