ABSTRACT:
A method of forming end pieces on plastic molding strips which have at least one longitudinally external hollow chamber within. The end pieces are formed by injection molding on the ends of the molding strip in a mold which receives the end regions of the molding strip. The end of the strip is seated against a capping element located in the molding cavity. The capping element serves both as a stopper which fixes the axial position of the strip within the molding cavity and as a capping element which seals the opening into the hollow chamber of the strip.
