Abstract
In order to provide a particularly homogeneous pressure and temperature profile in a gas cushion for the levitating support of glass or glass ceramic, the invention provides a device (19) for transporting or supporting glass ceramic or glass, which comprises at least one diaphragm (1, 2) that has at least one continuous bearing surface (3) and at least one gas feed chamber (51-55) and at least one gas discharge chamber (71-75), the gas feed chamber (51-55) and the gas discharge chamber (71-75) having a gas-permeable connection to the bearing surface (3).

A method for transporting and supporting glass ceramic or glass (11), the method comprising:
- generating a gas cushion (13) on which the glass or the glass ceramic (11) rests, the gas cushion (13) being generated over a continuous bearing surface (3) of a diaphragm (1, 2);
- supplying levitation gas is supplied to the gas cushion (13) via at least one gas feed chamber (51-55) arranged in the diaphragm (1, 2) and connected to the bearing surface (3) by a gas-carrying connection;
- and
- at least partially discharging the levitation gas of the gas cushion (13) via at least one gas discharge chamber (71-75) arranged in the diaphragm (1, 2) and connected to the bearing surface (3) by a gas-carrying connection, wherein the gas feed chamber is at least partially closed at the bottom, the levitation gas being introduced into the gas feed chamber through a downwardly directed gas-permeable connection in the diaphragm.
