Working reinforcement (2) of an aircraft tire, made by the zigzag winding of a strip (5) having width W, with a periodic curve (7), corresponding to the mid-line of the strip, forming, with the circumferential direction (XX′), a non-zero angle A. The circumferential distance (c) between the extrema (S51, S52, S53) of the respective mid-lines of two consecutive strip portions (51, 52, 53) is equal to the ratio W/sin A. For any set of three consecutive strip portions (51, 52, 53), made up of a first, a second and a third portion, the respective mid-lines of the first and third strip portions (51, 53) intersect at an intersection point (I), axially aligned with the extremum (S52) of the mid-line of the second strip portion (52) and axially on the inside of said extremum (S52) at an axial distance (a) at least equal to the width W.
