Production and Quality Improvements using Automatic Fabric Tension Controllers and Tension Monitoring

摘要

The precise and automatic control of the tension of machine clothing brings a very high return on investment,since clothing has a huge influence on:machine runnability and output paper quality the consumption of steam and chemicals.However,tension control gets very low priority in paper mills,even though its impact on the drive,guiding dewatering and formation,etc are well understood.Because the tension of the fabrics is influenced by ever changing production conditions,there is a need for monitoring and automatic control in wire,press and drying sections.
