Plant for building tyres of vehicle wheels and method for providing elongated elements to be used in a process for building tyres

A method for arranging elongated elements to be used in a process for building tyres for vehicle wheels, comprising:

• simultaneously winding a first elongated element and a second elongated element of a first type, respectively on a first winding support and on a second winding support by arranging the first elongated element in a first axial position on the first winding support and the second elongated element in a first axial position on the second winding support, wherein the first elongated element and the second elongated element of the first type are the same as each other;
• and
• simultaneously winding a third elongated element and a fourth elongated element of a second type respectively on said first winding support and on said second winding support by arranging the third elongated element on the first winding support in a second axial position different from the first axial position and the fourth elongated element on the second winding support in a second axial position different from the first axial position, wherein the elongated elements of the second type are the same as each other and are different from the elongated elements of the first type.
