Claim:
A device for applying a paper web onto a paper reel comprising: a web application roller mobile between a guiding position of the paper web and an application position of the paper web onto the paper reel; an actuator for moving the web application roller between the guiding position and the application position; and a locking mechanism for locking the web application roller in the application position, the locking mechanism including a second lever linked to a frame around a second axis and a third lever linked to the web application roller around a third axis, the second lever and third levers being linked to each other at a common fourth axis, the locking mechanism defining a dead center, the dead center being a configuration of the second and third levers in which the second axis, third axis and fourth axis are in a common dead center plane, and when the web application roller is between the application position and a position corresponding to the dead center, the second and third levers create a force directed to the application position in reaction to a force applied from the paper reel to the web application roller.
