摘要： A method of manufacturing an expanded graphite gasket comprises the steps of taking co-operating male and female mould members, the female mould member comprising a channel extending through a block from one face to a directly opposite face, the channel as seen in plan having a width and configuration corresponding to a desired gasket shape, presenting a substrate to one face of said block with said channel in register with said locations, filling the channel with a charge of expanded graphite particles, followed by pressing the charge with the male mould member onto the substrate to form a gasket thereon and thereafter removing the mould members.

摘要： A flat gasket incorporating a metallic reinforcement layer which is enclosed within the gasket in relation to one edge thereof is formed from relatively uncompacted, i.e. loose, expanded graphite particles by a method comprising the step of pressing such particles onto the opposed faces of said reinforcement substantially simultaneously to form compacted graphite foils in situ thereon while at the same time pressing some of said particles relative to said one edge to form a single unreinforced graphite foil portion extending from and integral with the other foils to enclose said one edge.
