The method of building and transferring a tread belt structure on a portable and collapsible building drum 10 mounted coaxially on a building machine 100 with a rotatable shaft 120 is disclosed. The method includes the steps of forming the annular tread belt 4 on the building drum 10 , transferring the building drum 10 with the tread belt 4 from the rotatable shaft 120 onto a pivoting transfer device 200 , pivoting the transfer device 200 about 90° rendering the tread belt 4 and axis of the building drum 10 perpendicular to a horizontal plane, collapsing the building drum 10 , separating the annular tread belt 4 from the building drum 10 , removing the tread belt 4 , expanding the tire building drum 10 , pivoting the building drum 10 into coaxial alignment with the rotatable shaft 120 , moving the building drum 10 onto the shaft 120 . The tread belt 4 has one or more elastomeric components applied while hot and the equipment provides means for weighing the tread belt 4.
