Felt seams “cocked”

1. If one side is leading, then tighten leading side.
— this makes the distance around greater so it takes slightly more time to get around than before.
The leading side then lags a little, until finally the other side catches up.
2. If inside edges are cocked, have press rolls reground.
3. Replace damaged felt rolls, or put patches of sacking or felt on rolls to make distance around greater in a restricted locality.
4. Check press and rolls for alignment.
— use concave felt rolls and avoid crumbing on felt.
5. Use concave rolls to straighten a felt line that leads too much at the center.
