摘要： During manufacture of a tyre for motor vehicles, one or more structural elements of elastomeric material, such as a tread band provided with a respective under-layer, are manufactured by laying a continuous elongated element on the carcass structure or other forming support, which elongated element is longitudinally divided into a first and second mutually-coupled portions that are obtained through extrusion of two different elastomeric materials coming from respective extruders leading to a common extrusion die. Laying of the coils takes place in such a manner that the first and second materials form a first layer and a second layer overlapping the first layer, respectively.
