The installation for manufacturing a bead wire intended to reinforce a pneumatic tire, said installation comprising a receiving table which is adapted to receive a braided torus which comprises a braid wire which extends longitudinally from a first end section to a second end section, a cutting tool, a crimping tool adapted to crimp a sleeve around said first and second end sections, and a configuration unit which is adapted automatically to switch the installation from a cutting configuration in which the receiving table cooperates with the cutting tool so as to position the braided torus and the first and second end sections so that said first and second end sections are sectioned by the cutting tool to a crimping configuration in which the receiving table cooperates with the crimping tool.

The method includes procuring an annular coreof main axis Z. The core is closed on itself by a core joinwhich occupies, in azimuth about said main axis Z, a first angular sector S. Then, a braiding is performed by helically winding, about the core, a braid wirethat is held closed by a braid join, of sleeve 9 type, which occupies a second angular sector S. A method during which a registration element, with respect to which the position of the first angular sector Sis known, is sought and detected on the core, and the azimuthal orientation of the coreis adapted during the braiding, with reference to said registration element, so that the second angular sector Soccupied by the braid joindoes not overlap the first angular sector Soccupied by the core join

A crimping station comprising a crimping tool designed to crimp a sleeve around a first end portion of a thread and around a second end portion of a thread, said crimping station comprising a sleeve preparation subassembly which has a feed device that supplies a metal strip and conveys said strip as far as a shaping device designed to plastically deform said strip in order to give said strip a concave curved cross section, so as to obtain a preformed strip, and then as far as a cutting device which is designed to sever a portion of length of said preformed strip in order to obtain a sleeve preform that a loading tool places within the crimping tool.
