Abstract:
1. A system for threading a running paper web from a preceding section to a following section of a paper-making or paper-finishing machine using a threading tail, comprising: at least one sensing element for sensing an actual path of the threading tail within a sensing area and providing output data corresponding thereto, said at least one sensing element being contactless with the threading tail, said at least one sensing element being configured for sensing a deviation of said actual path of the threading tail from an ideal path of the threading tail within said sensing area; at least one of a data collecting system and an analysis system connected to at least one said sensing element for receiving said output data; and at least one influencing element connected to at least one of said data collecting system and said analysis system, for influencing said actual path of the threading tail by influencing a draw of the threading tail dependent on said deviation from said ideal path.
