Abstract
A process for elimination of paper defects during continuous paper production which reduces time lost due to defect correction has the following steps: a) recognition and localization of the paper defect by means of sensors (5) directed at the running paper web (4); b) detection or calculation of the speed of the paper web (4) between the sensor (5) and a station (6) for defect correction positioned downstream from the sensor (5); c) on the basis of the speed of the paper web, calculation of the arrival time of the web segment with the paper defect at the station (6) for defect correction; d) before arrival of the web segment with the paper defect at the station (6) for defect correction, reduction of the web segment speed to a lower value than normal speed or to zero, e) automatic removal of the paper defect in station (6) for defect correction and f) restoring the web section to normal speed.
