Fundamentals and Practical Experiments of Heat Transfer in Calenders, 2003 Spring Technical Conference Proceedings
During supercalendering or soft calendering, an extreme pressure is applied on the paper under a certain temperature gradient. Heat applied to the paper softens the fibers, enhancing the mechanical effect. To find the best balance
between thermal and mechanical energy, it is worth understanding how heat is transferred from the rolls to the paper web. This requires fundamental work on heat transfer and practical trials to validate theory. The purpose of this work is to furnish certain results validating theory and to observe the effects of certain calender parameters (temperature of the heated rolls, dwell time, pressure and number of nips) and of certain paper properties (coated, uncoated and moisture) on heat.
