Claims (7)

1. Способ автоматизированного устранения дефектов бумаги при производстве бумаги в бумагоделательной машине со следующими стадиями: а) распознают, локализуют и измеряют дефект бумаги с помощью направленного на движущееся бумажное полотно (4) детектора (5); b) измеряют или вычисляют скорость бумажного полотна (4) между детектором (5) и расположенным пространственно за детектором (5) участком (6) для устранения дефектов; с) вычисляют на основе скорости бумажного полотна (4) момент прихода имеющего дефект бумаги отрезка полотна на участок (6) для устранения дефектов; d) автоматически устраняют дефект бумаги на участке (6) для устранения дефектов, отличающийся тем, что детектор (5) и участок (6) для устранения дефектов расположены вдоль непрерывно проходящего бумажного полотна, и что устранение дефектов бумаги проводят при непрерывном производстве бумаги при полной скорости бумажного полотна.1. A method for automatically eliminating paper defects in paper production in a paper machine with the following stages: a) a paper defect is detected, localized and measured using a detector (5) directed to a moving paper web (4); b) measure or calculate the speed of the paper web (4) between the detector (5) and the area (6) located spatially behind the detector (5) to eliminate defects; c) calculate, on the basis of the speed of the paper web (4), the moment of arrival of the defective paper segment of the web to the area (6) to eliminate the defects; d) automatically eliminate the paper defect in the area (6) for eliminating defects, characterized in that the detector (5) and the area (6) for eliminating defects are located along the continuously passing paper web, and that the elimination of paper defects is carried out during continuous paper production at full paper web speed. 2. Способ по п.1, отличающийся тем, что для предварительного и грубого измерения дефектов бумаги устанавливают перед детектором (5) дополнительный детектор. 2. The method according to claim 1, characterized in that for preliminary and rough measurement of paper defects, an additional detector is installed in front of the detector (5). 3. Способ по п.1 или 2, отличающийся тем, что момент прихода предварительно детектированного имеющего дефект бумаги отрезка полотна к детектору (5) вычисляют на основании скорости бумажного полотна (4) на пути к детектору (5). 3. The method according to claim 1 or 2, characterized in that the moment of arrival of the pre-detected paper-defect piece of web to the detector (5) is calculated based on the speed of the paper web (4) on the way to the detector (5). 4. Способ по любому из пп.1-3, отличающийся тем, что устранение дефекта бумаги осуществляют посредством покрытия поверхности дефектного места быстро отвердевающей текучей средой. 4. The method according to any one of claims 1 to 3, characterized in that the elimination of the paper defect is carried out by coating the surface of the defective place with a rapidly hardening fluid. 5. Способ по п.4, отличающийся тем, что текучую среду напыляют на дефектное место с одной стороны или с двух сторон. 5. The method according to claim 4, characterized in that the fluid is sprayed onto the defective place on one side or on both sides. 6. Способ по п.4, отличающийся тем, что текучую среду наносят на дефектное место с помощью валиков. 6. The method according to claim 4, characterized in that the fluid is applied to the defective place using rollers. 7. Способ по пп. 4, 5 или 6, отличающийся тем, что в качестве текучей среды используют УФ-лак. 7. The method according to PP. 4, 5 or 6, characterized in that UV-varnish is used as the fluid.
