Support for disk-shaped articles using the Bernoulli principle

A support (1, 100) for disk-shaped articles (11), comprising an annular nozzle (8) in a circular surface (9, 10) of the support (1, 100) facing the article (11), means for feeding said nozzle with compressed gas for the formation of a gas cushion between the support (1) and the disk-shaped article (11), and at least one projection (85, 90, 108) in the surface (9, 10) of the support (1, 100) facing the article (11) as a rest for the article, wherein 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), the projection (85, 90, 108) being provided at a radial distance outward from the axis (14) of the support (1, 100) but at a distance radially inward from the nozzle (8) and providing a rest for the article (11), the nozzle (8) being so shaped as to direct said 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, the projection (85, 90, 108) being elastically resilient in a direction perpendicular to the surface (9, 10) of the support (1, 100) facing the article (11).
