ABSTRACT:
A support (1, 100) for disk-shaped articles (11), comprises an annular nozzle (8) in a circular surface (9, 10) of the support (1, 100) facing the article (11). The nozzle is fed with compressed gas for the formation of a gas cushion between the support (1) and the disk-shaped article (11). At least one projection (85, 90, 108) in the surface (9, 10) of the support (1, 100) facing the article (11) serves as a rest for the articles. The projection (85, 90, 108) is arranged within the nozzle (8) provided in the surface (9, 10) of the support (1, 100) facing the article (11), at a radial distance outward from the axis (14) of the support (1, 100) but at a distance radially inward from the nozzle (8). The support thus provides a rest for the article (11). The nozzle (8) is so shaped as to direct the gas radially outwardly in all directions from the disk-shaped article (11), thereby to draw the article against the support (1, 100) by the Bernoulli principle.
