Abstract: The tire production device includes a main shaft and a turn-up rod assembly, a shim plate assembly, a lock block assembly and a middle drum assembly. The tire production method includes: adjusting initial diameters of the shim plate assembly, the lock block assembly and 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 it abut against and lock the tire rim; adjusting the diameter of the shim plate assembly and the middle drum assembly, so that outer surfaces are flush; turning over the turn-up rod assembly to adhere the sizing material to a tire side surface, and making the turn-up rod assembly move reversely and reset; 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.

Abstract: The present invention provides a middle drum assembly of a building drum, and a replacement method for a middle drum block of the middle drum assembly and a building drum.

Abstract: Disclosed are an adjusting method and an adjusting apparatus for an axial dimension of a middle drum assembly, and a building drum. The adjusting apparatus for the axial dimension of the middle drum assembly includes a first middle drum block, a second middle drum block, and an intermediate middle drum block located between the first middle drum block and the second middle drum block.

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.
