PROBLEM TO BE SOLVED: To easily and precisely form profiling turned along a bead-core to a carcass ply without damaging its joining strength, joining work efficiency, etc. SOLUTION: In a method for forming a profiling part K turned along the bead-core 5 in the winding part 6b of the carcass ply 6A, the carcass ply 6A is wound onto the winding surface 11S of a cylindrical former 11 in which at least two profiling channels 12 continuing in the peripheral direction to both end parts are formed on the winding surface 11S. After that, a profiled roller with a shape matching the profiling channel is pushed into the profiling channel and rotated so that the profiling part K is formed in the carcass ply 6A.
