Abstract
A novel method of producing molding members for automobiles, formed at least partly of a synthetic resin material is disclosed. According to the method of the invention, synthetic resin material is extrusion molded into a continuous body with a substantially constant cross-section throughout the entire length thereof. A controlled amount of the material is removed from a predetermined location of the continuous body, corresponding to a water flow blocking projection, synchronously with the extrusion molding of the material, such that the cross-section of the continuous body varies in the longitudinal direction of the body. The continuous body subjected to the controlled removal of the material is then cut into the predetermined length of the molding member.
