Paper Machine Doctoring

Dewatering and doctoring are not only related to energy consumption, but also play a big role in paper machine runnability, efficiency and profitability, as well as paper profiles. Therefore, a well-designed and operated paper machine dewatering and doctoring system is the key to a well-performing and energy-efficient press section. 

Optimized doctoring lead to increased dryness after the press section. Savings in dryer section steam usage are notable.
