Abstract
A method for feeding sheets in a feeding direction along a guide face of a sheet guiding device in a sheet processing machine includes forming an air cushion between the guide face and a respective sheet by providing an air pressure distribution resulting in air flows beneath the respective sheet. The air pressure distribution is based virtually only on the effect of viscosity of the flowing air and is then capable of carrying the sheet; a device for performing the method; and a sheet processing machine such as a printing machine including the device.
