Roll crowning is intended to ensure proper web alignment and mainly to count-er the effects of deflection. In a simple nip system, roller deflection is one of the main reasons for nip variations across the width of the roll face. This is primarily evident in all end loaded rollers. The roll will deflect or bend away from the nip, which causes
