Abstract

The present invention relates to a method for forming a steel radial tire for a vehicle and a device therefor. The rim cushion 27 and the nylon body wave (by the rim cushion 27 and the nylon body wave 24) are performed by the band drum 103. In addition to improving the attachment accuracy of 24), it is possible to improve productivity by matching the line balance.
