1. High accurately processed machine parts ensure the excellent mechanical performances and accuracies of the whole machine and provide the guarantee to produce the high quality green tyres； 2. During whole building process PLC are used，with touch screen type HMI operation used to perform the functions to set process parameters, store sizes, display building process and fault diagnosis etc.，enabled the easy operation and quick and direct change of the size data； 3. The main shaft with frequency converter is used，to satisfy the rotation speed needed when assembling or stitching； 4. The finger turn-down, bladder turn-up and push devices are used to ensure fully the tyre building quality； 5. The turn-down and turn-up devices are supported forward and backward movable on the linear guide rails of the bed plate，ensured the equipment accuracy and thus improved the tyre quality......
