Abstract (en)
According to embodiments described herein, a guiding device for contactless guiding of a web (1) in a web coating process under vacuum conditions is provided. The guiding device (111) includes a curved surface (110) for facing the web (1) and a group of gas outlets (112) disposed in the curved surface (110) and adapted for giving off a gas flow to form a hover cushion between the curved surface (110) and the web (1). The guiding device further includes a gas distribution system for selectively providing the gas flow to a first subgroup of the gas outlets (240,242,244) and for preventing the gas from flowing to a second subgroup (114) of the gas outlets.
