摘要

The cylinder head gasket is made up of a series of layers (1a.1 - 1a.5). Each of these is embossed to produce raised areas with a recess underneath, which are positioned so that the sheets only fit together when in the correct order and it then has the minimum thickness. An Independent claim is included for a method for making the gasket.
