  • Patent number: 4726532
    Abstract: Method and apparatus for reeling a web, suitable in the reeling of paper web, wherein the web is introduced over the mantle of a reeling cylinder and passed onto a reeling shaft on which the web is reeled. The pressure level in a wedge-shaped inlet nip defined between the reeling cylinder mantle and the incoming run of the web is adjusted to eliminate or reduce the positive pressure which would otherwise exist in the nip by ejecting air from the nip by means of a blowing member situated in connection with the nip. Air jets are discharged from the blowing member in a direction opposite to the direction of movement of the surface of the reeling cylinder and/or opposite to the direction of movement of the incoming web run and by means of the air jets, air is ejected from the inlet nip to reduce the pressure therein.
