Abstract

A calender for satining paper through roll gap formed between a heated hard roll and a soft roller having an elastic covering. Overheating of an edge region of the covering, i.e., the portion not covered by the paper to be satined, may be prevented by utilizing continuous insulation belts. The insulation belt may reduce the transmission of heat from the surface of the hard roll to the elastic covering, at least in the roller gap.
