DEVICE OR TRANSFERRING A FIBER WEB ABSTRACT OF THE DISCLOSURE A device for transferring a paper web from the press section into the dry end of a paper making machine. The web contacts a rotatable press surface, e.g. on a press roll, and travels with the press surface through a press nip against a backing roll, and thereafter travels with the press surface to a web removal place. The web is transferred by a suction device across an adjustable gap to a porous transport belt which transports the web toward a first dryer group. The first dryer group has a number of drying cylinders and a web support belt that transfers the web from drying cylinder to drying cylinder. Either a suction device or another intermediate transfer roll transfers the web from the transport belt to the support belt of the dryer group. An adjustable speed control device operates the drive to the press surface, the drive to the transport belt and the drive to the first group of drying cylinders and their respective support belt so that there is a positive difference in speed between the web at the press nip and the speed of the web at the transport belt with the web moving faster at the transport belt and a positive difference in speed between the speed of the transport belt and the speed of the web support belt with the web moving faster on the support belt.
