Bias tyre building machines form the green tyre on the building drum by applying cord ply, sidewall, tread, and other required components in sequence, then pressing them together as the tyre structure takes shape. Finger turn-up and bladder turn-up devices support the shaping stage around the bead area, while the air-cushion traction system helps feed the cord fabric sleeve with better positioning, lower deformation, and more even material density. Thanks to PLC control, functions such as operation, monitoring, alarms, and communication can be managed more easily throughout the building process.
