Water is removed from a wet paper web 1 by passing it between felts 5, 6 through a nip N1 between press rolls 7, 8, the latter having a suction zone 9, and between felts 5, 11 through a nip N2 between press rolls 8, 10 and then separating the web from at least felt 5 to prevent rewetting. The web may be further pressed in an extended nip press zone N3 formed between press rolls 13, 14 and felts 15, 11. Water may be removed from felt 11 by suction box 16. In a modification, the felt which extends around press roll 10 is separate from that which extends about press roll 14. <IMAGE>
