Tyre manufacturing process for improved footprint symmetry
The patent US12070974B2 outlines a novel process for manufacturing tyres specifically designed for motor-vehicle wheels. The process begins with the construction of a green tyre, which includes a carcass structure featuring a pair of beads and a tread band positioned radially external to the carcass. Notably, the outer profile of the green tyre is symmetric with respect to a mid-line plane. The subsequent step involves vulcanising and moulding the green tyre, during which the tyre undergoes deformation to create a specific angle between the tread band and the rotation axis of the final product. This process also includes an axial shift of the tread band relative to the mid-line plane, resulting in one end of the tread band moving away from the mid-line while the other end moves closer.
Further claims detail the characteristics of the tyre post-vulcanisation and moulding. Specifically, the beads of the tyre maintain symmetry relative to the mid-line plane, and the tread band exhibits symmetry in its radial half-section. Additionally, the tread band remains largely undeformed across each radial half-section after the vulcanisation and moulding process. This innovative approach aims to enhance the structural integrity and performance of the tyres while ensuring consistent symmetry and minimal deformation, which are critical factors in tyre manufacturing.
