Plant for building tyres for vehicle wheels

A plant for building tyres for vehicle wheels comprising:

• a) a first winding station configured to simultaneously wind 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 in respective first axial positions;
• b) an unwinding station configured to simultaneously unwind an elongated element of the first type and an elongated element of the second type from said first winding support or from said second winding support;
• and
• c) a building line comprising at least one forming drum operatively associated with the unwinding station to simultaneously receive an elongated element of the first type and an elongated element of the second type from said first winding support or from said second winding support,
• d1) wherein said first winding station is also configured to simultaneously wind a third elongated element and a fourth elongated element of a second type different from the elongated elements of the first type, respectively on said first winding support and said second winding support in respective second axial positions different from said first axial positions;
• or
• d2) wherein the building plant also comprises a second winding station configured to simultaneously wind a third elongated element and a fourth elongated element of a second type different from the elongated elements of the first type, respectively, on said first winding support and said second winding support in respective second axial positions different from said first axial positions,
• e) wherein the plant is configured to arrange the first winding support and the second winding support in respective first winding positions when simultaneously winding the first elongated element and the second elongated element of the first type,
• f) wherein the plant is configured to arrange the first winding support and the second winding support in respective second winding positions when simultaneously winding the third elongated element and the fourth elongated element of the second type, and
• g) wherein the plant is configured to move the first winding support and the second winding support from the respective first winding positions to the respective second winding positions.
