Method and device for preventing uncontrolled spread of powder in a printing machine

   
   

A method for conveying sheets, which have been printed in a printing machine, through a sheet delivery system above a sheet deposit pile by a sheet conveying device and, at the same time, dusting the sheets with a powder, and preventing uncontrolled spread of excess powder, includes interrupting a powder-laden air flow extending in a direction towards the printing machine along an empty strand of the sheet conveying device in a housing of the sheet delivery system at least at one interruption location between a free end of the sheet delivery system and the printing machine, so that transport of entrained powder in a direction towards the printing machine is prevented; a prevention device for performing the method; a sheet delivery system including the prevention device; and a sheet-fed printing machine in combination with the sheet delivery system.
