Abstract
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.
