Abstract:
A profiling calender includes an intermediate roll, a lower roll, and a pair of intermediate lugs. The intermediate and lower rolls are separated by a distance defining a height of a second profiling nip. The intermediate lugs are situated at ends of the intermediate and lower rolls and include two quarter-circle bearing surfaces that meet at the second profiling nip. Each end of the intermediate roll or each end of the lower roll is equipped with a collar fastened to the roll and positioned between the roll and a quarter-circle bearing surface of a corresponding intermediate lug. The collar enables a radius of the roll to be increased by a height equal to the separation distance in order to improve an appearance of edges of a profiled element produced by the calender.
