摘要： Higher-gloss paper grades, in particular paper grades with a Hunter gloss % above 40, are produced in an arrangement having pairs of calendering units (1, 3) disposed in the machine direction one after the other and apart from one another, which pairs are each formed of separate and different calendering units (1, 3) and in each of which the nip load in the latter calendering unit (3) is higher than the nip load in the preceding calendering unit (1). Advantageously, the calendering unit (1) placed first in the machine direction is an on-line long-nip calendering unit (1) and the calendering unit (3) placed after that in the machine direction is an on-line or off-line supercalender.

摘要： The present invention relates to a method for calendering a moving web (1) of paper or board. The web (1) is passed to a calender (2) and calendered therein. At least one quality of the calendered web (1) is measured at a first measurement point (3) adapted at a location downstream from the calender (2). Additionally, at least one quality of the web (1) entering the calender (2) is measured at a second measurement point (4) adapted at a location between the calender (2) and the preceding section of the line. A control variable (6) affecting the calendering effect on the calender (2) is controlled by a feedback control scheme based on the measurement result obtained from said first measurement point (3) and a control variable (9) affecting the processability of the web (1) to be calendered is controlled by a feedback control scheme based on the measurement result obtained from said second measurement point (4).

摘要： The invention relates to a method and apparatus for measuring the tension of a moving web. In the invention, a measuring beam (2)is curved so that a web moving over or under the measuring beam (2) forms an air cushion (3) of the air it transports between the measuring beam (2) and the web (1). The web (1) causes a force effect transmitted by the air cushion on the measuring beam (2). The tension of the web (1) is measured by measuring the force caused by the web (1) and transmitted by the measuring beam (2).
