PCT No. PCT/FI93/00058 Sec. 371 Date Oct. 18, 1994 Sec. 102(e) Date Oct. 18, 1994 PCT Filed Feb. 19, 1993 PCT Pub. No. WO94/19536 PCT Pub. Date Sep. 1, 1994.The multi-cylinder dryer of a papermachine includes a first tier of cylinders, where the web supported by a first dryer wire travels on the cylinders of the first tier of cylinders, as well as a second tier of cylinders, where the web supported by a second dryer wire travels on the cylinders of the second tier of cylinders. The first dryer wire travels from a cylinder of the first tier of cylinders to a first guide roll and delivers the web lying on its side facing the cylinder of the first tier onto the second dryer wire and, after having wound onto a second wire guide roll, again takes up, on its surface facing the following cylinder of the first tier, the web from the second dryer wire traveling through the second tier of cylinders. A section extending between the dryer cylinder and the first wire guide roll is provided on the web-free side of the wire with a nozzle for blowing air in the traveling direction of the wire into a gap between the wire and the first wire guide roll for producing a plenum zone facilitating the release of the web.
