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.

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 said deviations being patched using the re-reeler, guided by the defect map and preset patching rules wherein, 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.
A system in connection with a paper machine re-reeler, and off-line coating machine, in which the paper machine forming the web includes means for creating a defect map showing deviations and displaying it to the operator, and the system includes a computer application for maintaining patching rules and for guiding patching using the re-reeler according to the patching rules, and the coating machine has means for displaying the selected deviations to the operator, wherein the system includes means for monitoring the virtual location of a deviation through the coating machine and, if a possible web break occurs, for localizing the deviation relative to the web break, and means for providing feedback on the basis of this monitoring to the patching rules of the re-reeler, in order to optimize them.
