At the heart of every web converting process lie precision rollers. Designed to carry the web, laminate or coat it, cool it, heat it, or treat it, these cylindrical objects must be engineered and constructed with an exact eye for detail in order to meet the unique demands of any given application and system.

Heat transfer rolls are common in many converting processes today. As engineered film and specialty substrates become more prevalent, the use of these engineered rolls has increased even more. Yet, the physics of heat transfer rolls are often misunderstood. This can result in incorrect roll specifications and improper use that can directly affect web quality.
