Abstract
An automatic decurling apparatus is provided for webs of paper material in which two small diameter decurling bars are adjusted into both sides of the web run between two closely spaced rollers around which the web passes in an S-wrap. The decurling bars can be independently adjusted into the web in varying degrees to compensate for predominant curl in one direction of the web. Additional decurling can be obtained by chilling the rollers, incorporating high-intensity dryers in the web path or by moisturizing one or both sides of the web prior to its passing the decurling bars.
