Apparatus for arranging elongated elements to be used in a process for building tyres for vehicle wheels

An apparatus for arranging elongated elements to be used in a process for building tyres for vehicle wheels, the apparatus comprising:

• a first winding support configured to receive a winding of a first elongated element of a first type;
• a second winding support configured to receive a winding of a second elongated element of a second type different from the elongated element of the first type;
• and
• a coupling device comprising a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis, said coupling device further comprising an inner hub extending coaxially to the rotation axis, said first coupling body and said second coupling body are rotatably coupled with said inner hub,
• wherein the first winding support is mountable on and dismountable from the first coupling body and wherein the second winding support is mountable on and dismountable from the second coupling body,
• wherein the first coupling body and the second coupling body are configured to unwind the first elongated element from the first winding support at a first angular speed and to simultaneously unwind the second elongated element from the second winding support in a same unwinding direction and with a second angular speed, wherein the first angular speed is different from the second angular speed.
