Dryer felts

Life:
1. Use a weave appropriate to the machine and the grade mix.
2. Prevent oil and grease from ruining the edges.
3. Check the dryer felt run for mechanical troubles, for example, dragging felt rolls or misaligned rolls.
4. Avoid burning the dryer felt by leaving steam on felt dryers at full pressure during a break.
Open and straight:
1. An open felt is a clean felt.
— keep dryers clean.
2. Observe the felt run and check the stretcher occasionally for squareness.
3. Do not over tighten the felt.
— keep seam straight by adjusting one end of the stretcher if necessary.
— if adjustment is constant for more than one felt or is excessive, check alignment of felt rolls.
— on older machines, check alignment of dryers.
4. Ensure that inside of hood is kept free of paper dust.
5. Avoid over-drying sized papers at high temperatures.
Running ashore:
1. Maintain guides in good condition.
— have spare guides available to immediately replace any that are suspect.
2. Ensure that dryers and felt rolls are accurately aligned.
3. Check that felt rolls are not deflecting (look at seam).
