<p>A method of manufacturing high-gloss paper wherein paper is coated on both sides thereof and the coating dried and the paper thereafter passed into a compact calender having two or more roll pairs, each including a heated hard roll and a non-heated soft roll, wherein the roll surface of the hard roll in each pair is maintained at a temperature of 150-210 °C, the line pressure at 200-470 kN/m and the machine speed at 900-1,800 m/min. Apparatus for carrying out the method includes a coating station, a compact calender arranged in line therewith, and means for maintaining the temperature of the paper beneath the lignin softening point during passage of the paper through the calender.</p> |
