Abstract
An inverted dryer group having a single-wire draw in a multi-cylinder dryer in a paper machine, including steam-heated drying cylinders arranged in a lower row and against which the drying wire of the cylinder group presses a web to be dried into direct contact. Reversing cylinders or rolls of the dryer group are arranged above gaps between the drying cylinders inside a loop of the drying wire. A support wire is placed in contact with the reversing cylinders or rolls over a turning sector of about 60.degree. to about 120.degree.. The support wire is guided by guide rolls arranged in gaps between the reversing cylinders as well as by other necessary rolls. The web is pressed against the drying wire on the turning sector by tension of the support wire.
