Latest Patents

One of Naito's most recent patents is a groundbreaking process for producing self-sealing pneumatic tires and the corresponding apparatus. This innovation introduces a method for manufacturing tires equipped with a uniform sealant layer, eliminating the need for organic solvents and costly apparatus. The process involves several sequential operations, including:

1. Injecting a viscous sealant material onto the internal surface of a pneumatic tire after vulcanization molding.

2. Utilizing centrifugal force during rotation around the tire axis to diffuse the sealant material into a sheet form, thereby creating a sealant layer.

3. Injecting a cover material made of uncured rubber or resin onto the inside surface of the sealant layer.

4. Similar to the sealant layer, this cover material is also diffused into a sheet form using centrifugal force.

5. Finally, the cover sheet layer is hardened through exposure to electron beams, infrared rays, ultraviolet rays, or ultrasonic waves.

This innovative method has the potential to enhance the durability and reliability of automotive tires, revolutionizing the industry.
