    摘要： Cleaning equipment for cleaning a moving surface particularly in a paper machine includes a washing head with a chamber in it opening onto the surface to be cleaned and nozzle elements arranged inside the chamber. The cleaning equipment also includes vacuum means and removal means. The vacuum means are arranged in the washing head. In addition, the washing head is arranged to be movable relative to the removal means that are fitted in a fixed manner.

    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).
