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.

A web anti-wrap device for a web printing press comprising:
- anti-wrap means 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;
- and
- guide means for guiding said anti-wrap means for movement between a first position in which said anti-wrap means fulfills the function to prevent the broken web from wrapping, a second position in which said anti-wrap means is moved away from said first position to create a working space between said anti-wrap means and said printing cylinders or between said anti-wrap means and said processing device,
- wherein said guide means comprises rail means extending between said first and second positions, said anti-wrap means being movable along said rail means.
A web anti-wrap device for a web printing press comprising:
- anti-wrap means 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;
- and
- guide means for guiding said anti-wrap means for movement between a first position in which said anti-wrap means fulfills the function to prevent the broken web from wrapping, and a second position in which anti-wrap means is moved away from said first position to create a working space between said anti-wrap means and said printing cylinders or between said anti-wrap means and said processing device,
- wherein said anti-wrap means is mounted on a table disposed between said printing cylinders and said processing device, said table including said guide means for guiding said anti-wrap means for movement relative to said table.
A web anti-wrap device for a web printing press comprising:
- anti-wrap means 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;
- and
- guide means for guiding said anti-wrap means for movement between a first position in which said anti-wrap means fulfills the function to prevent the broken web from wrapping, and a second position in which anti-wrap means is moved away from said first position to create a working space between said anti-wrap means and said printing cylinders or between said anti-wrap means and said processing device,
- wherein said guide means is arranged to guide said anti-wrap means for pivotal movement about the upper or lower end of said anti-wrap device from said first position to said second position to create said working space.
