METHOD OF MAKING A GASKET

摘要

A gasket of the kind comprising particles of compressed expanded graphite bonded to an apertured reinforcement plate is made by pressing the graphite particles onto the face of the plate without lateral support of those particles at the periphery of the plate, as by pressing between two compressor belts. In thus dispensing with vertical moulding elements, the method enables a more uniform density of graphite to be obtained over the surface of the plate, and yet leaves the graphite coating at the periphery acceptably uniform with the remainder. The method is specially applicable to the manufacture of gaskets for the cylinder head of an internal combustion engine.
