1. An automatic plant for producing tyres, comprising:
a manufacturing unit comprising a plurality of work stations;
a plurality of devices for transferring the tyres from one work station to another work station and for moving the tyres within a same work station; and
a vulcanizing unit;
wherein each work station is designed to assemble one or more corresponding structural components of the tyres,
wherein at least one of the structural components is supplied from a machine for producing the at least one structural component, through a dynamic storage unit, and to at least one of the work stations, the dynamic storage unit having a first and a second winding reel, each winding reel having a lateral surface, a winding device for winding the at least one structural component on the first winding reel, and an unwinding device for unwinding the at least one structural component from the second winding reel, the winding device being capable of traversing at least a portion of said lateral surface of the first winding reel along an axis parallel to an axis of rotation of the first winding reel and the unwinding device being capable of traversing at least a portion of said lateral surface of the second winding reel along an axis parallel to an axis of rotation of the second winding reel,
wherein the winding device and the unwinding device operate independently of each other, and
wherein the vulcanizing unit comprises at least one vulcanizing mould for the tyres.
