NORWALK IE TUBES PHE HIGH QUALITY. "All bridges have been burned behind us by featuring the scissors test for ascertaining the quality of rubber used in a tube," declares the general manager man-ager of t he local Norwalk service station sta-tion operated by Guarantee Tire & Rubber Rub-ber company, -151 South Main street. "In introducing nnd making the scissors scis-sors test. the manufacturers of Norwalk Nor-walk tires have committed themselves to a quality product, and any deviation from the standard of quality now represented repre-sented would prove a catastrophe to their reputation. "The scissors test reveals tlie quality of ruhnor in a tube - with precision. It is made by taking a piece of tube one-quart one-quart er inch by three inches long and i stretching it to nine inches, three times ; its original length. If, when slightly ! snipped on the edge, it tears apart, the rubber is inferior. If, when snipped, it does not tear apart, it is positive proof of quality. "I r. 1 ')av id Spence. directing chemist at the Norwalk factory, i.s the only man in the world who i'i In possession or Die formula for producing the rubber used in Norwalk tubes. Ills method of refining and strengthening the rubber used in t hese tubes is a deep eeret . Norwalk factory has been built around I this method. No more dramatic or final j proof of quality for any type of mer-l mer-l ehandise than the scissors test of Norwalk Nor-walk is lu use today." r t
