Method of producing water drain shaft cover with inlaid damping strip

摘要

The elastomeric damping strip in at least one cover resting face of metal is laid into a depression of the metal face. The strip is made of a casting or spatula-filling elastomer mass (7) and protrudes over the resting faces, with its protruding part shaped by a tool (19). The tool is top-open and the elastomer mass is inserted in firm connection with the tool top side. The tool, alternatively, may be top-closed and the elastomer mass may be introduced via injection apertures (21), filling the tool cavity.
