KB40: How many rolls?

Resolution

Understanding certain basic principles of straightening is necessary to getting the best results. In simple theory, three staggered rolls should be sufficient to straighten any material so long as the degree of coil set remained constant. Since it does not remain constant, increasing in severity as the coil depletes, it would be necessary to continually adjust these rolls to obtain results. That is why a wide range of multiple roll machines are made, to take out the severest set without overstraightening milder set, and without requiring adjustment through the coil. The tip then is that the more rolls that are employed, the wider the range of coil set that can be effectively accommodated. As it happens, the thinner the material, the wider the range of set, so that thin materials usually require more straightening rolls.
