Abstract
Multi-cylinder dryer that includes several cylinder groups R1, R2. In the cylinder groups R1, R2, single wire draft or double wire draft is used in the first-mentioned group R1, whereas double wire draft is used in the last- mentioned group R2. The wires are arranged to control the paper web W which is to be dried via drying cylinders and the wire are controlled by guide rolls. Pulling of the paper web W occurs between the RV groups from one drying group R1 to another R2 between the last cylinder 12 of the preceding group R1 and the first cylinder 31 of the next group R2 in a tangential plane outside the cylinders 12, 31 in such a way that the paper web W coming from the preceding group R1 is run on wire 35 of the next drying group R2. During pulling the paper web W is held fixed on the leaving wire 13/receiving wire 35 by means of a suction box 20/blowing box 50. At the end of suction box 20/blowing box 50 a truncated roll 25 is attached with small diameter, which is supported and mounted by using the mentioned suction box 20/blowing box 50 as support body so that the suction/blowing zone begins as close as possible to the surface of receiving cylinders 31/leaving cylinders 12. <IMAGE>
