Abstract:
A method for manufacturing a belt structure of a vehicle tire, comprising the steps of:preparing, in a substantially-continuous manner, a belt assembly incorporating reinforcing cords substantially parallel to one another and inclined at a first predetermined angle with respect to a longitudinal axis of the belt assembly; cutting, in a substantially-continuous manner, the belt assembly along a first cutting direction substantially parallel to the longitudinal axis to obtain first and second substantially-continuous belt strips extending along two conveying directions substantially parallel to one another; supplying, in a substantially-continuous manner, the first and second belt strips to at least one assembly drum; and superposing on the at least one assembly drum portions of the first and second belt strips, each having predetermined length, to obtain a belt structure comprising radially-superposed portions of the first and second belt strips, wherein in each portion of the first belt strip the reinforcing cords are substantially parallel to one another, wherein in each portion of the second belt strip the reinforcing cords are substantially parallel to one another, and wherein in the radially-superposed portions of the first and second belt strips the reinforcing cords in the first belt strip are inclined in an opposite direction with respect to the reinforcing cords in the second belt strip.
