Claims

1. THE METHOD OF FORMING A ROD WHICH COMPRISES CONTINUOUSLY AND PROGRESSIVELY COMBINING A PLURALITY OF LONGITUDINALLY EXTENDING FIBERS AND AN ADHESIVE MATERIAL CAPABLE OF BEING HARDENED INTO AN ELONGATED ROD-LIKE MASS AND ENCLOSING THE ROD-LIKE MASS WITHIN AN ELONGATED EMBRACING MOLDING MATERIAL HAVING A SMOOTH CONTINUOUS MOLDING SURFACE CONTACTING THE ROD-LIKE MASS CAPABLE OF BEING DISINTEGRATED BY HEAT SO THAT WHEN THE ADHESIVE DOES HARDEN THERE WILL BE A SMOOTH CONTINUOUS SURFACE FREE OF RIDGES, TREATING THE ROD-LIKE MASS TO HARDEN THE ADHESIVE, AND HEATING THE ENCLOSED ROD-LIKE MASS TO DISINTEGRATE THE MOLDING MATERIAL.
