  • Method and apparatus for passing a printed web between the separated cylinders of a deactivated printing unit of a web fed rotary printing press
    Patent number: 5924619
    Abstract: A method and apparatus are provided for passing a printed web through the separated printing or blanket cylinders of a motionless downstream printing unit of a lithographic rotary printing press. First and second blast air devices are arranged on the first and second sides of the web, directing blast air into respective spaces formed between the running web and the cylinders, at a position located upstream of the cylinders. The blast air applies forces to both sides of the running web to thereby center the web on a path which is similar to the path taken by the web through the blanket cylinders during normal printing operation.
