Abstract

PURPOSE: To bend side ends of breaker material accurately and thus to mold a breaker layer in faulted structure efficiently by arranging a dual bladder on both sides of a drum flange operating radially.
CONSTITUTION: After winding and junctioning breaker plies 94a, 95b on an expanded drum flange 40, outer pladders 48, 48' arranged on both sides of the flange 40 are inflanted to bend a ply 98b along both sides 95, 95' of the flange 40. Next, the air is fed to inner pladders 49, 49' arranged in the interior of pladders 48, 48' to exhaust said pladders 48, 48', a breaker layer 94b is turned up to pressure welding with the pladders 48, 48' hanging over the flange 40, and then the pladders 48, 48', 49, 49' are exhausted. After a tread 96 is wound on the breaker layer 94b, the air is fed to an annular pladder 81 to contract a plurality of segments 75, thereby holding the breaker and the tread.
