The mechanism secures a screw (1d) of a tension roller (15) during transport or to prevent it from coming loose. The mechanism has a sleeve (6d) having an elastic material that is fixed onto the shank (2) of a screw (1d). When fitted, the sleeve is elastically deformed and is supported against a central bore (19) of the spacer element (17), ensuring that the entire assembly consisting of the tension roller (15), centering disc (18), spacer and screw is held together. |
