Latest Patents

Mangun's latest patents include a "Method and apparatus for grooving tire tread." This innovative method utilizes a computerized numerical controller to regulate the positional relationships between the tire and a hot cutting knife. The controller, through multiple servo motors, allows the tire to rotate in a vertical plane while enabling lateral and rotational movement of the cutter knife in two planes. During the cutting operation, the controller also manages the temperature of the cutting knife based on the contour of the cut and the cutting rate. This method achieves simultaneous five-axis control of the tire grooving operation while concurrently regulating the knife temperature.

Another significant patent is the "Tire bead core-apex assembly." In this invention, an apex is cohered to the bead wire bundle or core to create a unitary bead assembly. The core is supported on a rigid continuous planar surface, while the apex strip is supported on the uninflated inflatable cylindrical surface of a turn-up bladder arrangement. The inflation of the bladder arrangement rolls the apex outward to surround the bead core, achieving the appropriate radial orientation and shape. This innovative approach eliminates the need for conventional roller stitching due to the strong coherence between the apex and core.
