Extend Roll Life

Pressure indicating sensor film is cited by Beyer as being especially helpful with calendar rolls, which are swim rolls that have mechanisms to allow the center of the rollers to exert a different level of pressure. “Similar to crown rolls, swim rolls need to be carefully monitored to ensure even and exacting pressure is being applied to achieve optimum nip conditions,” says Beyer. “We use the film to create just the right nip and improve the roll shape and crown to deliver better sheet uniformity.”
