Abstract
The disclosure relates to a method for producing a circumferential packaging for a paper roll. The paper roll has a wound paper web and two opposing end faces and a circumferential surface that connected the end faces to each other. The method includes the following steps: applying a protective material in liquid form to an end section of the paper web by at least one application unit, the protective material being applied to one of two sides of the end section of the paper web, winding up the end section of the paper web, so that the end section forms at least one outer layer of the paper roll, and curing the protective material, resulting in a protective layer that covers the circumferential surface.

A method for producing a circumferential packaging for a paper roll, the circumferential packaging and paper roll is formed from a single paper web, the paper roll having two opposing end faces and a circumferential surface that connects the end faces to each other, the method comprising the steps:
- applying a protective material in liquid form to an end section of the paper web by at least one application unit, the protective material being applied to one or two sides of the end section of the single paper web,
- winding up the end section of the single paper web so that the end section with the protective material forms at least one outer layer of the paper roll, and
- curing the protective material after the winding up thereby creating a single protective layer that covers the circumferential surface of the single paper roll.
A method for producing an end side packaging for a paper roll, the paper roll having a wound paper web and two opposing end faces and a circumferential surface that connects the end faces to each other, the method comprising the following steps:
- providing an end cover that comprises a base body with an opening and a tab for covering the opening, the base body and the tab being designed as a single piece,
- arranging the end cover on a shaft in such a way that the end cover rests on an end side of the paper roll and the shaft extends through the opening,
- removing the paper roll from the shaft, and
- covering the opening with the tab.
