Abstract

A method for guiding web patching, using a re-reeler, in connection with a paper machine and an off-line coating machine, in which method a defect map of the web is created on the paper machine, to show deviations some of which are shown on the coating machine, using selected criteria, to the operator, the deviations being patched using the re-reeler, guided by the defect map and preset patching rules. On the coating machine, the virtual location of the selected deviations is monitored through the coating machine and if a possible web break occurs, a deviation is localized relative to the web break, and on the basis of this monitoring, feedback is provided to the patching rules of the re-reeler, in order to optimize them.
