Abstract:
The present application provides a tire production method and apparatus. The tire production apparatus comprises a main shaft, and a turn-rod assembly, a deck plate assembly, a locking block assembly and a middle drum assembly that are sleeved outside the main shaft. The tire production method comprises: adjusting the initial diameter sizes of the deck plate assembly, the locking block assembly, and the middle drum assembly, and pasting same; mounting a tire rim outside the locking block assembly, and increasing the diameter of the locking block assembly, such that the locking block assembly abuts against the tire rim tightly; adjusting the diameters of the deck plate assembly and the middle drum assembly, such that outer surfaces of the deck plate assembly, the locking block assembly, and the middle drum assembly flush with each other; the turn-rod assembly performing a turn-up action to apply a rubber compound to the side surface of a tire, and after applying the rubber compound, the turn-rod assembly performing a reverse action to return; reducing the diameters of the deck plate assembly, the locking block assembly, and the middle drum assembly, and removing the tire from the main shaft.
