摘要
This invention relates to a method for freely suspending a moving web of material in a gaseous medium, which comprises impinging a stream of the gaseous medium over the entire width of one surface of the web in order to produce a first stationary stable pressure zone, forming at least one stationary stable suction zone adjacent said first stationary stable pressure zone, deflecting the gaseous medium passing beyond the edges of the web in order to produce a second stationary stable pressure zone on the opposite side of the web, and regulating said pressure and suction zones in order to maintain the web in a freely suspended state. The invention also includes an apparatus for performing the method.
