TYRE INSPECTION

PROGRESS IN A LARGE FACTORY Inspection of tyres in the Goodyear factory begins with the raw materials. The fabric must all pass over a glasstop table, brilliantly lighted from beneath, to reveal any imperfections. The compounds are checked by the laboratory men. The rubber is inspected by experts. 9 The inspectors are in evidence through every step of the production process, in the wash room, the driers, especially in the mill room, to see that specifications as to time and temperature of milling are rigidly adhered to, in the compound room to see that quantities and weights are exact. They are especially exacting in the calender room where inspection of gauge and lieat is continuous. An inspector must pass on every tyre before the tread goes on, and after it goes on. He is very much on the job in the pit to see that pressures are kept up and that there is no overcure or under-cure. He gets his last shot at the tyre in final inspection where every detail is finally passed on. If the tyres are designed for an automobile manufacturer as original equipment for new cars, the tub€i is inserted and partially inflated before it leaves the factory. Otherwise the tyres are machine wrapped with paper and the tubes are folded in cartons ready for the dealer’s store or the customer’s needs.—“ Goodyear News/’
