ABSTRACT:
In a web anti-wrap device for a web printing press, anti-wrap means is disposed between printing cylinders and a processing device which is positioned downstream of the printing cylinders in the printing press, to prevent a broken web from wrapping around the printing cylinders. Guide means is provided for guiding the anti-wrap means for movement between a first position in which the anti-wrap means fulfills the function to prevent the broken web from wrapping, and a second position in which the anti-wrap means is moved away from the first position to create a working space between the anti-wrap means and the printing cylinders or between the anti-wrap means and the processing device.
