<p>Device for building a tyre having a drive unit (1) driving a drum shaft (2). Around the drum shaft a building drum having a first (3) and a second (4) building drum half is arranged. A pressure medium coupling (6) rotatable about the drum shaft is provided with pressure medium connections (7). Each building drum half is provided with a number pressure medium connections (8, 9). The pressure medium connections of the first building drum half are connected to the pressure medium connections of the rotatable pressure medium coupling by- means of a first tube set (12), wherein in the drum shaft pressure medium ducts have been arranged which at one side are connected to the rotatable pressure medium coupling and at the other side are connected to the pressure medium connections of the second building drum half by means of a second tube set (14). Each tube set (12, 14) is connected to a building drum half mounting ring (15,16), which building drum half mounting ring is connectable to the pressure medium connections of the building drum half in question, so that the pressure medium connections of the' building drum half in question are connected to the tube set by means of the building drum half mounting ring in question.</p> |
