Abstract (en)
[origin: EP1557490A1] In a papermaking process a paper web passes through a series of drums forming nip gaps. The final nip gap is formed by a hard drum and a soft drum. The soft drum (30) is interchangeable with a temperature-controlled assembly whose geometry interfaces with the hard drum. The temperature control assembly heats the hard drum and removes heat from the soft drum. Also claimed is a commensurate calender assembly in which the temperature regulation process is altered with a change in soft drum. The drum scraper is changed to match the characteristics of the respective soft drum. The temperature regulation process employs oil as the heating medium.
