ABSTRACT:
A method and tool are provided for forming a patterned gasket bead on a surface. The tool includes a first portion which has a first recess that defines a first recess surface, and a mateable second portion having a second recess defining a second recess surface. The tool also includes a gasket material flow path that has a chamber section, and that is formed by the first and second recess surfaces of the first and second portions mated together. The tool further includes a gasket patterning member that is mounted within the chamber section of the gasket material flow path. The patterning member as mounted within the chamber section defines, with the first and second recess surfaces, a patterned extrusion opening through a discharge end of the first and second portions for extruding a patterned flow of gasket material.
