Abstract

The invention relates to a method in threading of a paper web (PR) in connection with the reeling up process, wherein via a nip contact (NK) formed between a reeling cylinder (1) and a reeling core (2) entering the drive, a paper web (PR) guided over the reeling cylinder (1) is passed in full width to the opening of a pulper (P) below the nip contact (NK) before cutting the paper web (PR) and guiding the same to the reeling core (2). On the outer surface (1a) of the reeling cylinder (1), especially on a sector in which the outer surface of the reeling cylinder (1) and the paper web (PR) are in contact with each other, a pressure effect deviating from the pressure of the environment is exerted, said pressure effect being produced from a combination of a negative pressure and a positive pressure in such a manner that in the travel direction of the paper web (PR) the negative pressure effect is exerted on the paper web (PR) at least primarily before the point of location of the nip contact (NKL) of the final reeling, and the positive pressure effect is exerted on the paper web (PR) at least primarily after the area of location of the nip contact (NKL) of the final reeling.
