Abstract

A method for producing a composite sealing element, in particular for forming a seal at a retractable pane of a vehicle window, wherein the composite sealing element is produced from at least one extruded element portion and at least one element part formed by injection molding in a mold cavity of a mold, with the element part being molded onto an end face, bounding the mold cavity, of the extruded portion. A change in the dimensions of the composite sealing element as a result of the length of the extruded element portion differing from the nominal value is counteracted by changing the arrangement of the end face of the extruded element portion with respect to the mold cavity.
