Abstract (en)

The invention relates to a box-like elongated runnability component (10) and a method for a drying section of a paper machine or the like. The runnability component comprises an entry side surface (10a) and an exit side surface (10b), which are connected to each other at least by a lower surface, whereby the entry side surface, exit side surface and lower surface delimit the inner volume of the runnability component. Further, it has a first end and a second end (10', 10"), between which it extends in its length direction, as well as a first blowing element (11), which is arranged in connection with the entry side surface to blow air upwards, and a first sealing element (20), which is arranged in connection with the entry side surface, beneath the first blowing element, whereby the first sealing element divides the surface of the entry side into a first region and a second region. Furthermore, the lower surface of the runnability component is provided with a first suction element, which is formed by at least one suction gap or by at least one row of suction holes (31, 31', 31"), extending from the first end of the runnability component towards the second end thereof, wherein the runnability component comprises means for adjusting the size of the suction holes or the width of the suction gap.
