Tread Roller is a tool used in the tire retreading process to help apply tread rubber to a tire, remove trapped air, and ensure proper adhesion. This tool can be either manual or powered, and it plays a crucial role in the quality and durability of the retreaded tire. The process of using a tread roller is often referred to as “stitching.” Here’s a more detailed look at its functions and significance:

  1. Application of Tread Rubber: The tread roller helps to evenly apply the new tread rubber onto the tire carcass. This ensures that the tread is uniformly distributed and correctly positioned.
  2. Removing Trapped Air: As the tread rubber is applied, air pockets can get trapped between the rubber and the tire carcass. The tread roller is used to roll over the surface, expelling any trapped air. This is crucial for preventing air pockets that could compromise the tire’s performance and safety.
  3. Ensuring Adhesion: Proper adhesion between the new tread rubber and the tire carcass is essential for the retreaded tire’s durability and reliability. The pressure applied by the tread roller helps bond the tread rubber to the carcass, ensuring a strong and secure attachment.
  4. Stitching: The term “stitching” refers to the action of using the tread roller to smooth out and secure the tread rubber. It involves rolling the tool over the rubber surface to ensure it adheres properly and uniformly, eliminating any wrinkles or imperfections.

Overall, the use of a tread roller is a critical step in the retreading process, impacting the quality, performance, and safety of the retreaded tire.
