<p>Methods and apparatus for making reinforced concrete products wherein arrays of reinforcing rods are distributed and imbedded automatically during the introduction of concrete into a form. A novel reinforcing wire cutting-ejection mechanism is provided to throw off cut wire into concrete deposited in the form at any spacing and pattern desired. Novel hollow reinforced concrete poles having high tensile strengths are produced automatically in one embodiment.</p> |
