Radial tire comprising a carcass ply with a notched lap weld
Abstract:
A radial tire (10) having at least one belt enforcement (13) and one carc reinforcement (14) with at least one ply (20) of rubberized fabric (24) having radial threads (25) essentially parallel to the radial direction (xx'), the radial ply having at least one overlapping splice (21) formed by the overlapping of two edges (22, 23) of the said fabric (24) and being limited circumferentially by two borders (28,29), characterized in that the said splice (21), in each of the said edges (22, 23), has at least one cut (26, 27) located underneath the belt reinforcement (13) and splitting several radial threads (25). The tire according to the invention, compared with classical radial tires of the prior art, presents an external sidewall appearance that is clearly improved.
