Tire manufacturing equipment is designed for tire profiling and manufacturing. Strip builders, strip wrappers, roll lathes, roll grinders, profile inspection systems, and complete roll shops are included in this product area. Specialized tire manufacturing equipment is used to monitor and control the thickness and profiles of tires during manufacturing. Profiling systems often use optical techniques to rapidly gage the condition of the product on a production line. Processing parameters can be adjusted to ensure that thickness and profile specifications are met. Tire profiling systems are sometimes used by rebuilders or retreaders that recondition or retread used tires.
