ABSTRACT:
A method and apparatus for molding a door seal, such as for an automobile. The apparatus is provided with a first extrusion passage for extruding a molding material into a hollow portion of the door seal. A second extrusion passage is provided for extruding molding material into a bridge which spans across the hollow portion of the door seal. A molding material discharge member, such as a pipe, is movably inserted into the molding die and can be moved between open and closed positions relative to a molding material supply passage for permitting material to be intermittently extruded through the second passage, whereas material is substantially continuously extruded through the first passage, thereby permitting the bridge to be molded to the hollow portion at selected locations therealong.
