ABSTRACT:
A process for producing a reinforcing member in a form of a solid wire or rod that contains a highly oriented resin as principal component and in which a degree of orientation decreases from center to periphery of said solid wire or rod, said process using a die having a molding port comprising at least one concentric molten resin extruding nozzle having a side wall with an inner and outer surface and a projecting rod member disposed along a central axis of said nozzle, and said process comprising extruding a molten highly oriented resin through said nozzle as a lubricant is applied to the inner surface of the side wall of said nozzle. A process for producing a reinforcing member in a form of a hollow pipe having a solid wall with an inner and outer surface that contains a highly oriented resin as principal component and in which a degree of orientation of said resin decreases from the inner surface of the solid wall of the pipe to the outer surface. A process for producing a reinforcing member in a form of a hollow pipe having a solid wall with an inner and outer surface that contains a highly oriented resin as a principal component and which has a highest degree of orientation in a center between the inner and outer surface of the solid wall of the pipe.
