摘要

Production of a device for producing a circular gas bed for supporting a glass body (1) comprises forming a support body having several parallel channels (2); twisting the body around an axis; and fixing. The channels emerge on a supporting surface of the support body. Preferred Features: The twisted axis runs parallel to the channels. The channels have a width of 0.1-100, preferably 1-20 microns and are arranged spirally around the twisted axis.
