摘要： 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.

摘要： Disclosed is a process and a device for producing paper webs that are coated on both sides, in particular LWC papers, within a papermaking machine. First, one side of the paper web (1) is coated in a first coating station (8) and then dried. After that, the other side of the paper web (1) is coated in a second coating station (25) and then dried. Each coating station (8, 25) comprises an applicator roller (10), a mating roller (11) and, mounted at the applicator roller, an applicator mechanism (13) for indirect coating of the paper web. A flat roll doctor is used to meter the coating slip on the applicator roller (10). The coated paper web (1) is glazed using on-line glazing rollers (60).
