Tyre for vehicle wheels

Abstract

A tyre for vehicle wheels includes a carcass structure with at least one carcass ply formed by strip-like elements consecutively adjacent one after the other along a circumferential extension and having overlap zones along respective longitudinal edges superimposed on each other. Each overlap zone has, along a longitudinal extension thereof, terminal sections that are laterally opposite with respect to an intermediate section. The intermediate section of each overlap zone has an intermediate overlap width greater than a terminal overlap width of the terminal sections.

1 . A tyre for vehicle wheels, comprising:
 a carcass structure comprising at least one carcass ply formed by strip-like elements consecutively adjacent one after the other along a circumferential extension, the strip-like elements having overlap zones along respective longitudinal edges superimposed on each other, wherein:   each overlap zone has, along a longitudinal extension thereof, terminal sections that are laterally opposite with respect to an intermediate section, and   the intermediate section of each overlap zone has an intermediate overlap width greater than a terminal overlap width of the terminal sections.   
     
     
         2 . The tyre as claimed in  claim 1 , wherein each overlap zone has an overlap width progressively decreasing away from the intermediate section. 
     
     
         3 . The tyre as claimed in  claim 2 , wherein in each overlap zone, the difference between a maximum overlap width detectable in the intermediate section and a minimum overlap width detectable along the terminal sections is less than 0.5 mm. 
     
     
         4 . The tyre as claimed in  claim 3 , further comprising a belt structure at a circumferentially outside position to the carcass structure. 
     
     
         5 . The tyre as claimed in  claim 4 , wherein each of said strip-like elements has a longitudinal axis parallel to a geometric rotation axis of the tyre. 
     
     
         6 . The tyre as claimed in  claim 5 , wherein each of said strip-like elements forms a non-zero angle between a longitudinal axis thereof and a radial plane of the tyre. 
     
     
         7 . The tyre as claimed in  claim 6 ,
 wherein the carcass structure comprises at least a first carcass ply and a second carcass ply, and   wherein strip-like elements belonging to the first carcass ply have longitudinal extensions crossed with longitudinal extensions of strip-like elements belonging to the second carcass ply.   
     
     
         8 . The tyre as claimed in  claim 4 , wherein the intermediate section of each overlap zone has an axial size substantially equal to an axial size of the belt structure.
