Tire production method and apparatus

Abstract

Disclosed are present inventiona tire production method and apparatus. The tire production apparatus includes a main shaft and a turn-up rod assembly, a shim plate assembly, a lock block assembly and a middle drum assembly sleeved outside the main shaft. The tire production method includes: adjusting initial diameters of the shim plate assembly, the lock block assembly and the middle drum assembly, and adhering a sizing material; installing a tire rim outside the lock block assembly, increasing the diameter of the lock block assembly, and making the lock block assembly abut against and lock the tire rim; adjusting the diameter of the shim plate assembly and the middle drum assembly, so that outer surfaces of the shim plate assembly, the lock block assembly and the middle drum assembly are flush; turning over the turn-up rod assembly to adhere the sizing material to a side surface of the tire, and making the turn-up rod assembly move reversely and reset after the adhering is completed; decreasing the diameters of the shim plate assembly, the lock block assembly and the middle drum assembly and removing the tire from the main shaft. The present invention solves the problem in the related art that the replacement of tire size for a mechanical building drum is time-consuming and laborious.
