ABSTRACT:
An improved forming apparatus for a breaker layer to be used in a radial tire is described herein. The apparatus essentially comprises a drum device (D), a press contact device (A), first and second breaker material folding-wrapping devices (B) and (C), means for rotating said drum device (D), and means for moving said respective devices (A), (B) and (C) in the axial direction relative to said drum device (D) and for fixing them at predetermined positions. The drum device (D) includes a plurality of segments which have a width of their outer circumferential surfaces approximately equal to the width of the breaker layer to be formed, which can form a substantially cylindrical press contact surface with their outer circumferential surfaces, and which can expand and contract the diameter of said cylindrical contact surface. The press contact device (A) also includes a plurality of segments which can be displaced radially inwards and outwards, and which form a substantially cylindrical press contact surface with their inner circumferential surface concentrically with the cylindrical press contact surface of said drum device (D) when they are displaced inwards. The first and second breaker material folding-wrapping devices (B) and (C) are disposed symmetrically on the opposite sides of said drum device (D) and concentrically with said drum device (D). Each of the devices (B) and (C) is movable in an axial direction and includes a plurality of segments which can displace radially inwards and outwards and which are movable in the axial direction.
