Abstract: A turret for a tire building system having two drums with drum shafts mounted on the turret and adjusted so that the axes of the drum will be offset and parallel providing a compact turret assembly with a minimum shaft length and weight. The offset drum shafts provide for positioning of the drums in operating positions of different heights relative to the floor surface so that manual operations can be carried out at the lower drum position where there is easy access by an operator. Safety provisions are incorporated to disengage the motor and stop rotation of the turret if the motor does not stop and thereby protect the operator and the turret mechanism.
