    Why? What is supposedly happening? The sulfur is not covering the rubber very well.

    The idea is not to cover the rubber with sulfur but to blend it into the rubber changing the matrix of the compound the rubber will be rolled folded and rolled again and again the same way you would cut dry ingredients into dough.
    Never try to tell me it can't be done

    I doubt that Mr. Dunlop does it that way.
    I knew that sulphur had to be added to rubber to make it useful but I imagined some complex chemical operation, I never imagined that was just a matter throwing some powdered sulphur and mixing. Simples.
