GASKET MANUFACTURE |
摘要 |
An embossed sheet (S) coated at least partially with expanded graphite and suitable for use as a gasket (G) or as a component layer of a gasket, is manufactured by positioning a planar metallic sheet (10) between an upper embossing die (14) and a lower embossing die (18) with a layer of particles of expanded graphite (22) between one of said dies and a surface of the sheet (10). One of the dies (14) has a protuberance (16) to emboss a ridge (R) into the sheet (10) while the other die (18) has a recess (20) to receive the ridge (R). The method also comprises pressing the dies (14, 18) together to cause the particles to coalesce and form a coating (24) attached to the sheet (10) while simultaneously embossing said ridge (R) into the sheet (10). |
