Automated machine for unwinding and rewinding fabric reels, which comprises: - a support frame; - a group for storing said fabric reels, which comprises: - two or more abutment racks, which are guidedly connected to said support frame along a movement path and are each provided with: - a support beam extended along a main extension direction, - at least two support arms transverse to said support beam and each extended between a lower end mechanically connected to said support beam and an opposite upper end; - at least two concave abutment portions, each placed at the upper end of a corresponding said support arm and intended to receive a fabric reel in abutment; - first movement means mechanically connected at least to said support frame and arranged for moving said abutment racks along said movement path; - a group for unwinding said fabric reels, which is placed adjacent to said storage group and is provided with: - at least one conveyor belt, which is guidedly connected to said support frame, at least partially delimits a reception seat for a said fabric reel, is configured for being at least partially inserted between the at least two support arms of a selected said abutment rack and is actuatable in a first rotation sense in order to unwind a said fabric reel and in an opposite second rotation sense in order to rewind a said fabric reel; - second movement means mechanically connected to said support frame and to said at least one conveyor belt and arranged for moving said conveyor belt between an operating position, in which said conveyor belt intercepts the movement path of said abutment racks, and a non-operating position, in which said conveyor belt is spaced from the movement path of said abutment racks. - a support frame;
