Ajettavuuskomponentti ja menetelmä paperikoneen ajettavuuskomponentin käyttötehokkuuden parantamiseksi

The invention relates to a structural element (1), which is adaptable into a runnability component (2) of a drying section of a paper machine or the like, preferably as retrofitting. The structural element comprises an elongated frame part, a compressed air nozzle (4) arranged in connection with the elongated frame part, and attachment means for attaching the frame part to the runnability component. The runnability component comprises an elongated box- like frame structure, the volume of which is limited by a first and a second side, and upper and lower sides connecting them, and a sealing member ( 3 ) arranged on the first side of the frame structure, i.e. on the entry side of the runnability component. The structural element is arranged on the first side of the frame structure of the runnability component, beneath the sealing member. The invention also relates to a method for improving the efficiency of a runnability component of a paper machine or the like.
