ABSTRACT:
This invention relates to a method of continuously extruding thermoplastic material with a solid, hollow or open cross-section, in which a liquid medium is continuously applied to the surface of the material being extruded before it leaves a nozzle which shapes the cross-section of the extruded material to the desired profile, and the surface of the material being extruded is also roughened, either before, simultaneously with or immediately after the application of the liquid medium, but before the material leaves the nozzle.
