Method for applying powder to a printed sheet and printing press for carrying out the method |
摘要 |
A method for applying powder to a printed sheet includes ejecting air flows from a nozzle bar. The air flows are set in such a way that the air flows which are ejected per meter length of the nozzle bar produce a resultant force acting on the printed sheet of from 0.5 newtons to 16 newtons. A printing press for carrying out the method is also provided. |

1. A method for applying powder to a printed sheet, the method comprising the following steps:
ejecting air flows from a nozzle bar; setting the ejection of the air flows per meter length of the nozzle bar to produce a resultant force acting on the printed sheet of from 3.5 newtons to 10 newtons; transporting the printed sheet past the nozzle bar with a transport device including:
a first chain conveyor having a first pair of endless chains carrying front gripper bars, anda second chain conveyor having a second pair of endless chains carrying rear gripper bars; and holding a front edge of the printed sheet with one of the front gripper bars and simultaneously holding a rear edge of the printed sheet with one of the rear gripper bars during transport.
