Building is the process of assembling all the components onto a tyre building drum. So it include first stage and the second stage .In the first stage operation, where inner liner, body plies and sidewalls are wrapped around the drum, the beads are placed and the assembly turned over the bead. In the second stage operation, the carcass of the tyre is inflated, then the belt package and tread are applied. The final product of the TBM (Tyre building machine) process is called a green tyre, where green refers to the uncured state. Some building machine has only one stage like VMI.
