In a method of manufacturing moldings and an apparatus therefore, a ridge piece 20 protrudes from a molding main body 10 of a molding 1 in a lip manner is removed gradually from a leading end side to a root side by a lip removing piece 33 moving together with a second die 32 which changes the extrusion contour of the molding main body 10, then the ridge piece 20 is removed by the movement of the second die 32 without decreasing the thickness of the ridge piece 20 thinning. Accordingly, the ridge piece 20 can be removed effectively by the simple operation and apparatus without requiring the operation such as the after-treatment, which can result in the improvements of the productivity of the molding 1, the appearance of the molding 1, and the reliability.
