Partnership doesn’t end with placing an order or delivering a product.
After the arrival inspection, the customer has received a new or serviced roll that meets the agreed requirements. When a roll arriving from Finbow is sent to the customer’s storage, the storage must be dry and have an even temperature, and it must be free from shaking and vibration.
Installation and supervision, installation tools
Lifting and installing a spreaded roll requires high precision and caution. The Finbow experts provide customers with instructions and guidance in order to ensure correct operation. We also supply purpose-made lifting aids for spreader roll handling.
Running time monitoring, troubleshooting, consultation, training
The Finbow services include troubleshooting, consulting, and user and operation training for maintenance crew and operators so that the machinery can be operated at full speed.
The patented Finbow solutions enable more running metres for the roll and extend the maintenance intervals by as much as several years. Transportation and handling are part of the training as well.
Removal and supervision tools
The roll is transferred with caution ready to transport.
Disassembly and assessment
The roll is dismantled and the agreed maintenance is conducted. In addition to metal rolls, Finbow can service rubber rolls as well. The customer receives an illustrated report of the evaluation and measurements done during dismantling. After this, decisions concerning the work content are made together with customer, based on facts.
Decision on service content and verification the roll’s suitability to the process
Once the roll has been opened and measured, the service content is agreed upon with the customer. Before starting the actual work, the operating conditions of the roll are checked, such as the running speed range and temperatures and humidity conditions.
At the same time we check that the design speed of the roll matches the actual speed range of the paper machine. This quality assurance is conducted on new, maintained and upgraded rolls.
Designing, upgrading and maintenance of the roll
We consider for example the following factors when designing a new roll or roll maintenance/upgrade:
• special conditions of the paper machine and roll position
• paper quality produced
• actual running speed range and temperature
• the first and second critical vibration frequency and their multiples.
The maintenance cost of the roll per one operating hour must be as low as possible. This is why the performance of the new roll being manufactured or maintained is tested as close to running conditions as possible.
Quality assurance and pre-delivery control before shipping
Vibration tests are conducted on the roll at all speeds. At the same time the vibration of the roll is measured in order to determine its vibration characteristics. Quality of the roll and its adherence to the running values agreed on with the customer can be ensured. This extends the operating life of the roll.
