Abstract
PURPOSE: To assemble an unvulcanized tire accuretely by a carcass layer being a expanded in a closed cylindrical surface, a cylindrical carcass layer is assembled on a cylindrical rigid body surface provided in the interior of the carcass layer and is formed into a toroidal shape.
CONSTITUTION: The carcass layer a is assembled on a ply former A, bead cores b are placed, and then the lower part of the bead cores are gripped by bead locks, F1, F2 and the carcass layer (a) is expanded. In this case, since a closed cylindrical surface can be formed by case formers B1, B2 placed on the outside of the ply former A, the carcass ply between the bead cores b is expanded to a roughly cylindrical shape while restricting it in the radial direction and promoting the expansion to the side. A cylindrical rigid body surface is formed by shoulder formers C1, C2 on the inside of the cylindrically expanded carcass ply, followed by folding and bonding works for the carcass ply and bonding works for tire side walls and shoulder members.
