ABSTRACT:
The weather strip is intended for application to the edge of an opening or a closure element for the body of a motor vehicle, this edge having successive, substantially straight portions connected by corner portions with small radii of curvature. The strip includes an anchoring section to which a tubular sealing section also of elastomeric material is connected, this being co-extruded with the anchoring section. The tubular sealing section has first and second longitudinal portions intended for connection to corresponding substantially straight portions and to corresponding corner portions of the said edge, respectively. The wall of the tubular sealing section, in the second longitudinal portions, has a thickness which is greater than the thickness of the first longitudinal portions; the increase in thickness is achieved during extrusion of the weather strip.
The invention also relates to an extrusion head for making such a weather strip.
