Abstract

A digital printing machine includes a printing bar for inkjet printing. The printing bar is mounted to be movable into a working position and into a retracted position. An adjustable roll and a spring-mounted roll form a first assembly and are disposed opposite one another. A rail forms a second assembly and is located between the adjustable roll and the spring-mounted roll when the printing bar is in the working position and is not located between the adjustable roll and the spring-mounted roll when the printing bar is in the retracted position. One of the two assemblies is disposed on the printing bar and the other of the two assemblies is separate from the printing bar.
