    摘要: A method and apparatus for heating a paper web in a calender in which the paper web is heated before it is passed into a calendering nip of the calender. The paper web is heated by a source of radiation and the heat radiation coming from the source of radiation is condensed and guided by a reflector face or an equivalent optical device onto the paper web and/or onto a face of one of the rolls in the calendering nip substantially directly before the calendering nip.

    摘要: A method for calendering a paper web, including the steps of passing the paper web through a calendering nip having a profile formed from a pair of calendering rolls, wherein at least one of the pair of calendering rolls includes a soft exterior face at least in the region of the nip, regulating the profile of the calendering nip to compensate for flaws in the paper web passing through the calendering nip including varying the properties of the soft exterior face locally in a direction transverse to the direction of the passing paper web concurrently with the passing step.
