It is an object of the present invention to precisely and efficiently
paste a tread ring and a raw tire base body with each other. A ring-like
base body 5 is aligned with a former 3. The ring-like base body 5
relatively approaches and separates from a former 3. The ring-like base
body 5 includes pasting means 6 which pastes a tread ring A to a raw tire
base body B. The pasting means 6 includes a grasping tool 11 having a
plurality of segments 13 which abut against an outer peripheral surface
of the tread ring A to grasp the tread ring A. The pasting means 6 also
includes a pushing-down pasting tool 12 having an annular rubber tube
body 15. The rubber tube body 15 is disposed on each side of the segment
13 and pushes down a shoulder side portion As of the tread ring A by
expansion to paste the shoulder side portion As to the raw tire base body
B.
