Shifted Layers at Winding
Is your wound roll straight? Does the side look like a phonograph record or a neatly stacked deck of cards? Or do you use words like shifted, feathered, telescoped, dished, or offset to describe the side of your roll?
Let's talk about the top cause of lateral position error in wound rolls.
On the road to straight rolls, we divide the causes of lateral errors into four categories.
1) the web shifts prior to entering the winding roll
2) the web shifts after entering the winding roll
3) the web shifts in storage or handling
4) the web shifts upon unwinding
Write in with any area you'd like to know more about.
