Abstract:
A method for conveying printed sheets, which comprises:conveying printed sheets through a delivery housing of a printing machine with a chain conveyor having gripper systems, a conveyor transport-run operatively running along a first conveyor path in a sheet transport direction and a conveyor return-run running along a second conveyor path in a reverse direction, and simultaneously dusting the printed sheets with a powder by using a dusting device and preventing uncontrolled spread of excess powder borne by an air flow induced by the conveyor return-run; limiting the air flow by using side walls of the delivery housing and an upper limiting device disposed above the conveyor return-run and a lower limiting device disposed below the conveyor return-run between the conveyor transport-run and the conveyor return-run; defining an interruption location with the upper and lower limiting devices at the second conveyor path; and interrupting the air flow at the interruption location.
