  • Patent number: 6739599
    Abstract: The present invention provides elongated moldings in which the occurrence of unintended curves is prevented and which can be installed while accurately conforming to the shape of the installation area. The molding body (121) of the elongated molding (120) provided by the present invention is formed by joining, in at least some parts in its longitudinal direction, two or more plastic molded members having mutually different mold shrinkage rates; in at least some parts of the molding body consisting of said two or more plastic molded members, two or more curved areas (120a, 120b, and 120c) having mutually different curvatures are formed adjacently to each other in the longitudinal direction; and the configuration within the cross section of the two or more plastic molded members, which can be seen in the cross section of the molding body, varies between two adjacent curved areas among said two or more curved areas.

  • Patent number: 6196615
    Abstract: A windshield molding which is installable in the space between a windshield and a periphery of a window opening of a vehicle body panel. The windshield molding includes a pair of extruded side molding parts, a pair of extruded corner molding parts, and an extruded upper molding part integral with and extending between the side and corner molding parts. Each of the side molding parts associated with each side edge of the windshield is greater in thickness as compared with the upper end corner molding parts, where a water drain channel is formed. A windshield molding is also provided which drains rainwater smoothly through the rainwater groove provided at necessary sections and having a different depth in the longitudinal direction for better drainage which can be produced simply and continuously as a single molding without the addition of cutting or other processes.

  • Patent number: 6170219
    Abstract: A flange of a panel is inserted into an extrusion port of an extrusion molding die through an insertion slit, which opens laterally of the extrusion port, to thereby form a molding space that corresponds to a trim member between the extrusion port and the flange. A material for forming the trim member is extruded forwardly of the extrusion port through the molding space. The die and the flange are moved relative to each other while adjusting the insertion depth of the flange into the extrusion port so that the distance between a reference on the panel and the trim member is maintained at a desired distance. Thus, a trim member is extrusion molded on the edge of the flange of the panel and is mounted thereon simultaneously, thereby accurately mounting the trim member on the in a desired outer shape.

  • Patent number: 5662851
    Abstract: A molding method which provides a relatively simple structure, while also providing a pleasing appearance which is adaptable to a variety of ornamental and artistic applications. The molding is produced by extruding an ornamental core, and joining trimming portions to the sides of the ornamental core. Where the ornamental core and trimming are formed of materials which can be readily joined together, the trimming is melt bonded directly to the side surfaces of the ornamental core. Alternatively, a foil laminate can be provided, and the ornamental core is joined to an upper layer of the foil laminate, with the trimming joined to a lower layer of the foil laminate. If desired, the width of the ornamental coil can be changed during extrusion molding, such that the width varies along the longitudinal direction of the molding.
