ABSTRACT:
The present invention is directed to a method and apparatus for drying a web of paper utilizing impulse drying techniques. In the method of the invention for drying a paper web, the paper web is transported through a pair of rolls wherein at least one of the rolls has been heated to an elevated temperature. The heated roll is provided with a surface having a low K value of less than about 3000 w.sqroot.s/m.sup.2 c and having a low porosity. The surface material of the roll is preferably prepared from a material selected from the group consisting of ceramics, polymers, glass, inorganic plastics, composite materials and cermets. The heated roll may be constructed entirely from the material having a low K value or the roll may be formed from metal, such as steel or aluminum, or other suitable material which is provided with a surface layer of a material having a low K value.
