Abstract: A process for applying a belt structure during the manufacture of a large heavy duty tire such as for an earthmover machine including forming a belt band 5 obtained by adhering together two rubberized fabric strips 8, 9 so as to be laterally offset with respect to each other. Each strip has reinforcing cords 8a, 9a disposed according to symmetrically cross-biased orientations. A belt band made of at least two adhered together strips is wrapped on the carcass 2 of a tire being manufactured with one or more complete turns around the radial outer circumferential surface of the carcass. The end edges 5a, 5b of the belt band 5 are cut perpendicularly to the longitudinal axis thereof and are disposed to overlap each other with the amount of overlap ranging between 20 and 80 mm.
