Abstract: An extrusion molding process including a first tape adhering process, in which a first tape is guided to a surface of a first seal lip of an outer belt molding, which is in a heated state in a die, by a tape guide passage formed in the die of an extrusion molding machine and the first tape is adhered to the first seal lip, and a second tape adhering process, in which a second tape is guided to a surface of a second seal lip of the outer belt molding, which is in a heated state immediately after coming out from the die, by a tape guiding jig arranged adjacent to a downstream side end surface of the die of the extrusion molding machine and the second tape is adhered to the second seal lip, are performed.

Abstract: Stable burning of waste combustible gases is assured even in a strong wind by using an improved ground flare stack. The stack, which is a cylinder containing burner nozzles therein, is provided with a fence surrounding the lower part of the stack, a roof extending outwardly from the stack above the fence, a louver at the opening between the fence and the roof for directing the air stream to the roof, and a circumferential baffle installed at the circumference of the bottom part of the stack. A preferable shape of the baffle is a truncated cone. Preferably, the stack has a fluidic diode, at the inside top thereof.
