Idle roller ( 20 ) is moveable in a slot ( 50 ) and in direction which is never coplanar with the plane (Y) that contains the axes of the rollers ( 18 & 20 ). The angle θ between the direction of movement of the idle roller ( 20 ) and the plane (Y) containing the axes of the rollers when the nip is formed can vary between about 30 and 90 degrees.
Winding Better Rolls - Paper, Film & Foil Converter
This does two things. First, it orients web tension perpendicular to winding nip force, making the winding nip load independent of tension. Second, if the winding nip roller deflects or skews, a 180-deg nip wrap ensures it will be perpendicular to the entry span, reducing the likelihood of tracking or wrinkling.
How to Make Great Flakes with a 32" Flaking Mill - CPM
The roll feeder then evenly distributes the seeds across rolls in the flaker, which encourages uniform wear. In addition, the large diameter of the 32″ roll offers a steep nip angle, which allows material to pass through the rolls with ease. No matter the model of flaker, roll maintenance plays a major role in consistent flake thickness.
