Abstract:
1. A method for positioning bead cores during a building of a radial tire carcass in a tire-building machine, the method comprising: positioning first and second bead cores on respective first and second core-centering devices, on a first side of a carcass drum; centering the first and second bead cores; grasping, with a second core-setting device, the second bead core; transporting the second core-setting device and the second bead core to a second side of the carcass drum; grasping, with a first core-setting device, the first bead core; and setting the first and second bead cores onto the tire carcass in respective first and second bead core positions by the first and second core-setting devices, wherein the tire building machine comprises first and second bellows supports with bellows, and wherein: wherein the centering of the first and second bead cores occurs through enlargement of diameters of the first and second core-centering devices, and wherein the second core-setting device and the second bead core are transported to the second side of the carcass drum to a waiting position axially beyond the second bead core position during a building of the tire carcass, and the method further comprising moving the first core-setting device together with the core-centering devices and the first bellows support adjacent the first side of the carcass drum away from the carcass drum to provide a free space to allow the positioning of the first and second bead cores and removing a preceding tire carcass.
