    Abstract: A pneumatic tyre which is provided radially outside a carcass (6) with a belt (9) made of cords (10) embedded in topping rubber, wherein each of the belt cords is composed of three steel monofilaments (12) including at least one waved steel monofilament (12A) and at least one unwaved steel monofilament (12B), the three steel monofilaments (12) being compactly twisted together so as to make alternate contacting portions and noncontacting portions (P) between the at least one waved steel monofilament and the at least one unwaved steel monofilaments, and the gap (T) therebetween at each noncontacting portion (P) is not more than 0.6 times the diameter (d) of the waved steel monofilament (12A).

    Abstract: A helical cord having an elliptical shape and the like is manufactured so that a length-to-width ratio or a dimension of a shaped form of the cord to be shaped in a longitudinal direction can be changed. A cord (C) is sequentially passed through through holes (21H, 22H) of stationary and movable shaping bodies (21, 22) opposing each other of a shaping device (20). At that time, the movable shaping body (22) is moved along the stationary shaping body (21) by a moving device so that the through holes (21H, 22H) become eccentric with respect to each other, and the cord (C) passing between the eccentric through holes (21H, 22H) is bent and deformed so as to be shaped. Also, a first and a second displacement mechanism that displace the movable shaping body (22) in X- and Y-directions are provided in the moving device, the movable shaping body (22) is thereby reciprocatingly displaced in the both directions in synchronization by displacement amounts which were set, respectively, the movable shaping body (22) is continuously moved in response to the displacements in the both directions, and thus the passing cord (C) is shaped.
