1. A dosing apparatus for a machine for producing unit dose articles using a cylindrical forming surface, including first and second dosing units each comprising:
a nozzle support body,
a plurality of nozzles having respective fluid delivery apertures, carried by said nozzle support body and connected to a fluid delivery system via at least one flexible tube, and
a movement control unit configured for moving the respective nozzle support body along a closed-loop path that forms a continuous loop having a lower delivery section configured to move in a machine direction of the machine and an upper return section that is spaced apart from the lower delivery section and configured to move in a direction parallel to and opposite the machine direction of the machine,
wherein the movement control units of the first and second dosing units are configured for moving the respective nozzle support bodies independently of each other along said closed-loop path.
