Felt tension

1. While wetting out a new felt, some shrinkage occurs.
— slacken back to allow for this when running the felt.
2. It is advisable to have felt stretchers graduated so that running length of felt is known at all times.
3. Maintain trade line with a slight lead at the center.
4. When running the felt, tighten the stretcher to keep pace with stretch of felt.
5. Periodically check the automatic stretchers or check felt tension and adjust manual systems for proper felt tension.
