    Abstract: A group with single-wire draw in a dryer section of a paper machine having heated smooth-faced drying cylinders against whose smooth face a paper web to be dried is brought into direct contact, and reversing cylinders. The group with single-wire draw also includes a drying wire which is guided in a loop by guide rolls as well as by the drying cylinders and reversing cylinders so that the drying cylinders are placed outside the wire loop and the reversing cylinders are situated in gaps between the drying cylinders inside the loop of the drying wire. In the group with single-wire draw, the drying cylinders include large cylinders and small cylinders, the diameter of the large cylinders is substantially larger than the diameter of the small cylinders. The small cylinders are placed in gaps between the large cylinders so that their centers of rotation are on a level substantially different than the level of the centers of rotation of the large cylinders.
