Abstract
Dryer section of a paper machine having so-called normal drying groups with a single-wire draw, heated contact drying cylinders arranged in an upper row and leading cylinders or rolls arranged in a lower row. At least one drying module is arranged between and/or inside the normal drying groups and in which the opposite side of the web, in relation to the side of the web placed against the contact-drying cylinders, is placed against the heated cylinder face of a single large drying cylinder or cylinders in the drying module. The web is placed in direct contact against the heated cylinder face of the large drying cylinders. The drying module includes a separate loop of a drying wire which guides the web and presses its opposite side against the heated face of the large cylinders over a sector which is greater than about 180.degree.. The diameter of the large drying cylinder(s) is larger than the diameter of the contact drying cylinders in the normal drying groups.
