Abstract: The method comprises steps during which, by making the cylindrical form rotate in a first circumferential direction, the ply is deposited until the front edge and performs a complete rotation. A point of penetration is marked on the ply on a cutting line, and a cutting blade that is driven in translation is made to penetrate between two wires placed on the cutting line at the point of penetration. The cylindrical form is made to rotate in an opposite second circumferential direction while displacing the cutting blade in a first transverse direction until the cutting blade is disposed at a predetermined and non-zero distance from a first selvedge. Without retracting the cutting blade from the wire gap, the cylindrical form is made to rotate in the first circumferential direction while displacing the cutting blade in an opposite second transverse direction until the cutting blade emerges at a second selvedge.
