System and method with azimuth control, for sorting tire bead cores

A method for producing a bead wire intended for the reinforcement of a tire, such as a pneumatic tire, said method comprising:

• a step (a) of procurement of a core during which a core is procured which forms a ring having a main axis, said core being in f act held closed on itself at a core junction which occupies, in azimuth about said main axis, a first angular sector,
• a braiding step (d) during which at least one braid wire is helically wound about the core, over at least one turn about the main axis,
• a step (e) of production of a braid junction, during which a first end section of the braid wire and a second end section of the braid wire are joined together by crimping a braid sleeve about the first end section of the braid wire or by welding the first end section of the braid wire and the second end section of the braid wire together in order to keep said braid wire closed on itself about said main axis, said braid junction occupying, in azimuth about the main axis, a second angular sector,
• a detection step (b) during which a registration element, with respect to which the position of the first angular sector is known, is sought and detected on the core,
• a positioning step (c) during which said registration element is taken into consideration to adapt the azimuthal orientation of said core, with reference to said registration element, upon the implementation of the braiding step (d), so that, at the end of the steps (d) of braiding and then (e) of production of the braid junction, the second angular sector occupied by the braid junction does not overlap the first angular sector occupied by the core junction.
