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).
A runnability component for a drying section of a paper machine, the machine having a pocket space between two drying cylinders and one turn roll, the pocket space being formed by a first drying cylinder, a second drying cylinder located after the first drying cylinder in the longitudinal direction of the machine, a turn roll located between, and offset from, the first and second drying cylinders, and a wire supporting a web and travelling from the first drying cylinder to the turn roll and from the turn roll to the second drying cylinder, a first web run being formed between the first drying cylinder and the turn roll and a second web run being formed between the turn roll and the second drying cylinder, with the web running on an outer surface of the wire relative to the pocket space and on the periphery of the turn roll, the runnability component comprising:
