KB43: The odd roll principle.Category: Straightening Process | Updated: 6/4/2007 3:11:02 PM | Owner: The Professor | Read: 1981 (Last: 6/17/2013 7:42:11 PM)
ResolutionMost coil stock straighteners are equipped with an odd number of rolls, with the extra roll generally in the lower bank. This is because material is generally uncoiled from the top of the coil, placing the coil curvature with the “belly up” so that the straightening rolls want to be always pushing upward. An advantage of this arrangement is that a slight upward curvature can be induced into the straightened material through careful adjustment. Such a curvature helps slide the material more readily through the die.
