Abstract
An air cushion guide for sheet or web-formed material includes at least one guide member formed with nozzle openings through which air is blown between the guide member and the guided material for supporting the guide material on a supporting air cushion located above the guide member, at least one of two variables consisting of volumetric air flow emerging from the nozzles and flow speed between the guide member and the guided material being adjustable independently of one another so that a proportionality between the two variables is nullified or neutralized; and a method of adjusting a flotation height.
