Abstract
A transporting apparatus includes a transporting plane and a transporting platform which can be displaced in different directions in a largely friction-free manner on an air cushion above the transporting plane, the air cushion being generated by air nozzles which are distributed in the transporting plane and are adapted to be optionally opened and closed individually in each case by a valve. Compressed air flows out of the air nozzles in the upward direction from beneath through the transporting plane, and the valves of the air nozzles and the transporting platform are designed such that they interact with one another depending on the position of the transporting platform. The valves of the air nozzles are designed as solenoid valves equipped with a magnet coil, and the transporting platform has ferromagnetic regions that interact with the magnet coils of the solenoid valves in dependence on the position of the transporting platform.
