    摘要: The invention relates to an apparatus for extruding a polymer profile directly onto the surface of a glass plate and particularly along a peripheral edge thereof. The extruded polymer profile is provided with a sealing and centering lip located on and projecting over the circumferential peripheral surface of the glass plate. The extrusion die has at least one supply channel for the polymer to be extruded. One supply channel or portion thereof leads the polymer material substantially to the portion of the die orifice directed toward the center of the plate. The other supply channel essentially supplies the portion of the orifice directed toward the outside. The supply channel may be provided with a shutoff device which regulates the volume flow. The regulation of the shutoff device takes place as a function of the radius of curvature (R) of the path covered by the extrusion die.
