Felt tension control

1. Ensure that the stretchers are free.
— check their movement with conventional felts when paper goes off the machine.
2. Know maximum tension that can be applied without springing felt rolls.
3. Record the weights that are added or subtracted in the stretcher.
— an automatic stretcher system is preferred.
— if automatic system is provided, the meaning of the air cylinder pressure in kPa per cm of tension must be known.
— the tension settings should be recorded and reasons for any change noted.
4. With conventional felts, make sure that the steam is reduced to the felt dryers when there is no paper over the machine.
5. Check that felt-drying air is evenly distributed.
