Tire Curing Press 6

Pneumatic tire in the early, using the rubber-coated canvas as carcass. Because canvas vertical lines and horizontal lines cross each other when walking due to the deformation of the tire, causing friction line so that lines can easily be the breaking point, then the tires just 200-300km. In 1903, j · F • Parmesan invented synthetic textile, this Twill textile of invention led to the development of cross-ply tires, tire life took a big step forward. Because inclined forks carcass not friction due to tire of walking, cord is not easy to be ground breaking, so substantially longer service life. In 1930, Michelin made the first tubeless tire 1946 invented the world famous radial tires. Therefore, the tire is has gone through a long process of development, in the night, I do not know how many people worked hard labor and high intelligence
