Abstract: Method for manufacturing a green tire using a building drum and a transfer device. In the method tire components are arranged on a building drum. In one step of the method the transfer device is placed around the building drum. The method further comprises a step during which a last manufacturing process for a green tire is carried out on the building drum, and a removal step during which a removal device removes the green tire from the building drum, wherein the removal device is provided with projecting elements that can be placed up to a distance from and around the outer circumference of the green tire and which projecting elements can be placed such so as to engage the outer side of the green tire. The removal step further comprises during the step in which the transfer device is placed around the building drum, placing the projecting elements up to a distance from and around the outer circumference of the building drum.
