The invention relates to an arrangement and a method of a paper machine or the like for saving energy in the drying section. According to the invention, in the drying section of a paper machine or the like in connection with a pocket space (9) between two drying cylinders (1, 2) and one turn roll (3), there are the following delimiting said pocket space (9) : a first drying cylinder (1 ), a second drying cylinder (2), a turning suction roll (3) and a wire (5, 5a, 5b), which is arranged to travel from the first drying cylinder (1) to the turning suction roll (3) and from there on to the second drying cylinder (2). The arrangement further comprises a box-like runnability component (10) and a sealing element (19) arranged in the lower part of the runnability component (10), in the gap between the runnability component and the turning suction roll (3) in order to seal said gap and thereby to promote the operation of the turning suction roll (3).
