Crowning Benefits - Paper, Film & Foil Converter

The roll will deflect or bend away from the nip, which causes pinching at the ends as seen in Figure 2. Roller deflection means there is bending due to its dimensions, material, and the load being applied to the roll in its particular application. Therefore, roll crowning is one common method of reducing nip variation caused by roller deflection.
