- Reeling
- Optimize secondary arm mechanics to wind a uniform roll with minimum bulk loss. Also reduce reel breaks and improve yield in converting.
- Rewinding
- Compute roll unweighting curve to wind a uniform roll while conserving bulk and stretch. Also set draws and speeds.
- Conformal Lips
- Contoured profiles of the suction lips, such as Uhle box, dewatering and pick-up slots reduce the contact psi against the felt, thus reducing felt and lip wear.
- Negative Crown Roll
- A felt roll crowned negatively straightens the bow, resulting in uniformity of drainage, suction, nip mechanics and felt wear across the deckle.
- Crowning
- Develop crown curve for rolls in contact to produce a uniform line load. Special cases considered are: multiple roll stack, skewed rolls, rubber covered rolls and zero-crown rolls.
