Understand how tension, edge alignment, surface pressure and speed changes interact to create a stable fabric roll.
Four indicators of a good roll
Controlled edges, limited wrinkles and trapped air, balanced roll hardness and no surface marking are the main quality indicators.
Why constant tension may not be enough
As roll diameter grows, the same torque can create a different surface tension. Material stretch and roll build must be considered.
