Abstract

A method is disclosed by which an air pressure different from the atmospheric pressure is generated and distributed to a sheet of paper in a sheet feed printing machine, comprising the step of generating a work-pressure in means arranged to discharge the work-pressure to the sheet and thereby to effectuate or control the transport of the sheet in the printing machine. The method is characterized through a continuous adjustment of the work-pressure that is discharged from each singular discharge means or from each singular set of discharge means to a work- pressure which is adapted to the subject sheet and/ or the subject process in the printing machine, and which is operative for control or transport, in response to detecting at all times the work-pressure discharged from each singular discharge means or from each singular set of discharge means. In analogy herewith an assembly in a sheet feed printing machine is disclosed, the assembly comprising means that are movably arranged in the printing machine and arranged for discharging to a sheet of paper a pressure that is different from the atmospheric pressure, and by means of the discharged work-pressure effectuates or controls the transport of the sheet in the printing machine. The assembly is characterized in that the discharge means comprises means for continuous adjustment of the discharged work-pressure to a work-pressure which is adapted to the subject sheet and/or the subject process in the printing machine, and which is operative for control or transport, in response to detecting at all times the work-pressure being discharged from each singular discharge means, or from each singular set of discharge means.
