Method of producing a toroidal road vehicle tire carcass

A method of producing a toroidal road vehicle tire carcass comprising two parallel annular beads, and a toroidal reticulated structure connecting the two beads and comprising a number of elongated reinforcing elements located between and extending substantially radially in relation to the beads;

• said method comprising the steps of forming said elongated reinforcing elements from a single continuous cord wound in such a manner as to form a succession of substantially identical groups of elongated reinforcing elements, wherein each group is defined by a first and second U-shaped loop having respective open ends and respective closed ends arranged side by side in an alternating manner along an annular interconnection line lying substantially in a plane between the bead planes;
• and said single continuous cord being wound about a respective one of said beads during formation of the first and second loops, and having the open end engaging the closed end of the other loop.
