Doctoring affects machine runnability, paper and board quality, production costs, and production efficiency. Runnability can be improved by optimizing doctoring parameters and blade materials. Cleaner rolls result in better end-product quality. The blades can be selected to meet customers shutdown schedule which will lead to fewer blade changes resulting in lower blade costs. The reduction of unplanned shutdowns and costly downtime periods can be avoided by reliable and trouble-free doctoring.
