Abstract

In a process for manufacturing metal sheet gaskets coated with elastomer, as are often used as cylinder head gaskets or as compressor gaskets in refrigerant circuits, it is proposed that the elastomeric coating be applied to the individual metal sheet in a spray coating process in order to be able to carry out the coating with elastomer in a more cost-efficient manner.
