Abstract
A method of retaining a sheet on at least one of a transfer cylinder and a guide surface of a sheet-guiding device in a sheet-processing machine by pneumatically activatable nozzles for producing an air cushion beneath the respective sheet, which comprises producing an air cushion by an air-pressure distribution resulting in air flows beneath the respective sheet, the air-pressure distribution being based virtually only on radially decelerated air flow, and being capable of retaining the respective sheet in position; and a retaining device for performing the method.
