Elias Retulainen (Inventor)

    Research output: PatentPatent application


    The invention relates to a method and an apparatus for manufacturing paper, and to a press in a paper machine. A fibre web (3) is supplied to a web processing unit (4a) that comprises two endless bands (5, 6) which are impermeable to air and which are arranged to turn around turning rolls (9a, 9b; 10a, 10b) and to run part of the way parallel to each other. The first band (5) is heated and the second band (6) is cooled, and the fibre web (3) is led on a felt or a wire (7, 8) between the bands (5, 6) so that the fibre web (3) touches the heated band (5). A press section is formed between the bands (5, 6), which press section is so long that the fibre web (3) is subjected in the web processing unit (4a) to pressing and at least partly to drying.
