A composite foot is described for supporting and moving pneumatically a machine. The foot comprises a nozzle (12) for ejecting pressurized air, fixed to the machine base (10) to which a substantially disc-shaped element (30) is associated, being connected to the nozzle (12) in a substantially swingable manner, between said disc-shaped element (30) and the machine base (10) there being provided air sealing means (38) in order that air is ejected by said nozzle (12) only toward the plane on which the machine is placed, thus generating in practice a pressurized air cushion which keeps the machine itself upraised with respect to the plane, thus allowing a quick and precise shifting thereof. |
