Abstract

A method of making a breaker for a pneumatic tyre provides for obtaining at least one rubberized closed annular band (1) by helical wrapping of a cord thread (2). Then the band (1) is alternatively bent over inwardly and outwardly an even number of times at an angle to its edges corresponding to the inclination angle of the cord thread (2) in the finished breaker (3), in such a way that the bend lines (4, 5) form the edges of the breaker (3). The invention may be used for making breakers of pneumatic tyres for different types of wheeled vehicles. <IMAGE>
