Wound roll structure

paper on a roll must is subject to various stresses during unwinding, therefore the paper must be wound onto the roll according to precise controls to ensure quality and consistency

Roll structure is determined by many parameters, including process speed, tension, nip load, and torque differential (TNT). When wound-in-tension is not correct, the roll may develop crepe wrinkles or bursts causing breaks in the pressroom.
