I show how you can sometimes do a field realignment of a single misaligned roller without having specialized precision optics. However, it will require you to have a solid knowledge of the web handling topics of rollers and wrinkles.
Bonus Material - Answers to Quiz
Slide 5 - Can solve misalignment wrinkle by moving EITHER 2 OR 3 horizontally, because either can bring the two rollers into parallel. That means you have 4 bearing housings to choose from for correction.
Slide 6 - Top 3 rollers and 2 intermediate bottom rollers need only be precision leveled (a move much easier than square) because that will bring those spans into parallel. Square is probably not needed. The entry and exit rollers will need a full (level and square) alignment.
