Abstract: Doctor blades are stored and used in a paper/board mill in which the quantity of the doctor blades used is monitored, and information is transmitted by data transfer means (20) to a data management system (23, 24) of the manufacturer/supplier of the doctor blades to manage the doctor blade situation. In the method, the information about the doctor blades is received by data collection means (22) connected to the data management system. The information is processed in the data management system (23, 24). When needed, a doctor blade/doctor blades is/are delivered to the paper/board mill to keep the quantity of doctor blades as desired. The system has data transfer means (20) for transmitting the quantity of the doctor blades to a data management system (23, 24) of a supplier/manufacturer. A means may be provided for giving the alarm to deliver, when needed, new doctor blades to the paper/board mill.
