摘要： The invention relates to a press for a machine for producing a fibrous material web, including at least one press nip formed between a press roller and a counter press roller of the press for guiding through the fibrous material web in a dehydrating manner, and two band shaped covers, which are each guided by multiple guide rollers in continuous circulation, so as to run together through the press nip, so that the fibrous material web is guided through sandwiched between said covers, and then separated again at a separation point, in order to continue guiding the fibrous material web on the one cover and separate it from the other cover. One guide roller of the guide rollers arranged at the separation point is a suctioned guide roller of the one cover, to hold the fibrous material web on the one cover at the separation position.

摘要： A machine for dewatering and drying a paper, cardboard or other fibrous web, to which machine a fibrous stock suspension is fed which is formed at least partially from waste paper. The machine includes at least two press nips which are formed in each case by two press rolls, wherein a fibrous web runs through first press nip with a water absorbing dewatering belt on both sides. The fibrous web then runs through a second press nip with at least one other dewatering belt and a smooth impermeable transfer belt on both sides. A transfer belt transfers the fibrous web after second press nip to a belt in a downstream machine unit, e.g. dryer group. The dryer group allows the fibrous web to be guided in a serpentine manner alternatively over heated dryer cylinders and vacuum equipped guide rolls.
