A decurler is a device that corrects curl occurring in a web. When material is wound onto a core to forming a reel, the web is deformed to follow the radius of the reel. When the reel is unwound and the diameter of the reel reduces, the web retains some memory and does not lay flat but instead has a curve effect called curl. Curl is removed bending the web in the opposite direction using rollers of various diameters. As the reel gets smaller, the curl increases and do the amount of decurl affect must be increased. Care should be taken to avoid cracking of the web surface. The decurl adjustment is often automated.
