Abstract
A turn-up device, comprising a building machine main shaft, an outer sleeve device, a ply down finger assembly, a bladder device, a bead setting device, and a bead locking device. The outer sleeve device, the ply down finger assembly and the bladder device are all sleeved on the building machine main shaft. The outer sleeve device is located on the outer sides of the ply down finger assembly and the bladder device along the radial direction of the building machine main shaft. The bead setting device is located on the outer sleeve device. A tire building method using the turn-up device can improve the building quality of tire beads, improve the service life of capsule, and provide promising precision of carcass.
