Apparatus for transferring and setting bead part assemblies for tires

A process for building pneumatic radial tires comprising (a) a step of switching a first building drum at a first building position and a second building drum at a second building position in a turret manner by turning a body of a building machine, (b) a step for forming a belt cover layer at said second building position by winding at least one fiber cord continuously and spirally on a reinforcing belt that has been previously wound on the building drum, (c) a step for completing a belt-tread assembly at the first building position by winding a cap tread on a belt cover layer that has been previously been wound on the building drum at the second building position concurrent with the operation for winding the fiber cord that is being carried out at the second building position, removing the tire belt-tread assembly from the building drum, and newly winding a reinforcing belt on the building drum from which the belt-tread assembly has been removed, and (d) repeating said steps (a), (b) and (c).
