Abstract
An automobile windshield molding is produced by a molding machine having dies. A method of producing the molding includes the step of extruding molding material through a hollow portion formed by the dies. The shape of the hollow portion is changed by moving the dies according to the cross-sectional shape of the molding, thereby widening part of the hollow portion of the dies to increase the thickness of the molding material. One of the dies is projected into the widened part of the hollow portion to form a water drain channel on a large thickness portion of the molding.
