Abstract
A process for producing a smooth and glossy surface on a paper web and a calender arrangement for carrying out the process are disclosed. The calender arrangement comprises two sets of rolls through which the paper web is conducted in succession. Each set of rolls comprises a highly heated hard roll and a soft roll. A cooling device arranged upstream of at least one of the nips formed between the roll sets restricts the amount of heat transfer to the inner layers of the paper web and the attendant, undesirable partial plasticization of the inner layers of the web.
