Abstract: A window molding for automobiles has an elongate leg fitted into a gap between a perimeter of a front window glass and a window frame. The molding holds the perimeter of the front window glass between an inner support and an outer support. A head is disposed at one end of the leg, the head having a lateral portion thereof extending over the outer support. A guide connects the lateral portion of the head and the outer support, the guide defining a distance between the lateral portion of the head and the outer support and being deformed according to a respective position along the perimeter of the front window glass. A guide groove is defined at least in part by the guide and opened toward the front window glass at least at side edges of the front window glass. A veil lip is disposed on the lateral portion of the head and forms an obtuse angle therewith at least at the side edges of the front window glass so that the veil lip extends toward the front window glass and defines another part of the guide groove.

Abstract: A method is provided for forming an elongate body having thickness change, such as a car window molding. In the method, a vertical member is extruded into a fixed wall thickness and a fixed outline. A horizontal member is extruded into the same outline as that of the vertical member but has a smaller wall thickness than that of the vertical member. An apparatus is provided to perform the method. The apparatus has a slide core axially reciprocating in a bore of a die so as to change a shape of a forming space.

Abstract: Molding a hollow shaped body which has a skin made of a synthetic resin and a hollow portion therein by a mold block provided with a mold cavity in the shape of the hollow shaped body, a tub into which an excess amount of the synthetic resin can flow and a small flow path communicating between the mold cavity and the tub. The process includes forming the skin of the hollow shaped body by injecting a molten synthetic resin into the mold cavity to fill up the cavity. Thereafter, a gas is introduced into the injected synthetic resin to thereby form the hollow portion. The gas injection forces a part of the synthetic resin out of the mold cavity and into the tub through the small flow path.
