Building Up an Automobile Tire in Rubber Plant, Akron, Ohio.
The material that has been used to make up this automobile tire has passed through many machines and has been worked on by many other skilled workmen before it has reached this workman. This man is carefully trimming one of the many layers that make up this large tire. Before this tire is finished, it must be placed in a steel mould of just the right size and tread design. This mould has a metal center part which will keep the inside of the tire hollow and in shape. While in that mould the tire will be heated very hot and at the same time be subjected to great pressure. After that process the tire will go to the inspection room. There it will be thoroughly examined. Those tire that are found to be perfect will be shipped away to be sold. If any are not quite prefect, they will be marked "seconds" and sold at a lower price than the perfect ones.
You may see this very tire pass you on the road, for it is being made for one of the large, swift buses that carry passengers from one city to another.
To realize the importance of tire manufacturing you have only to remember that all automobiles must be equipped with tires, and then think of the many purposes for which automobiles are used. Perhaps you will think first of the many automobiles used for pleasure. Next remember that there is hardly a great business in the world that does not make use of automobiles. All cars used for these, and many other purposes, must have tires; therefore, tire manufacturing has become a great industry of our country.
