  • Patent number: 10822189
    Abstract: The invention relates to a method of threading a fibrous web (W) onto a circular cylindrical object (3, 19) in a reel-up (2) for a paper-making machine (1). The reel-up (2) comprises an endless flexible belt (6) mounted for rotation along a predetermined path of travel. The endless flexible belt (6) is positioned adjacent the circular cylindrical object (3, 19) during winding and the fibrous web (W) residing on the outside surface (8) to engage the circular cylindrical object (3, 19) during winding such that the endless flexible belt (6) is deflected from the predetermined path of travel. When a fibrous web (W) is to be threaded onto the circular cylindrical object (3, 19), the circular cylindrical object (3, 19) is placed at a distance from the endless flexible belt (6) such that the endless flexible belt (6) is no longer deflected from the its path of travel.

  • Patent number: 9555993
    Abstract: A winding apparatus for winding a web material onto an empty core and into a roll, having a winding drum for guiding the web material supported on a first side, and cutting device for cross-cutting the web material prior to winding of it onto an empty core. The winding apparatus has air nozzles for ejecting compressed air onto the first side of the web material near a free end of the web material. By ejecting a gas, which preferably could be compressed air, onto the free end of the web, the free end is blown towards the empty core which is rotated. When the free end of the web material comes into contact with the rotating empty core, due to the ejected gas/air, the web will easily be “caught” by the rotating empty core, even without tape or adhesive, and a smooth new roll of web material wound.

  • Patent number: 9511968
    Abstract: The invention relates to a reel-up (1) for receiving and winding into a roll (2) a paper web (W) that arrives from a drying cylinder in a paper making machine and for starting a new roll (2) from a tail (19) formed by cutting the paper web (W). The reel-up (1) comprises a rotatably mounted reel spool (3) onto which a paper web (W) can be wound to create a paper roll (2) of increasing diameter; and an endless flexible belt (4) mounted for rotation along a predetermined path of travel such that the flexible belt (4) forms a loop. The flexible belt (4) is positioned adjacent to the reel spool (3) to engage the paper web (W) against the reel spool (3) during winding such that the flexible belt (4) is deflected from the predetermined path of travel by an amount relative to the amount of paper material wound on the reel spool (3).

  • Publication number: 20130075520
    Abstract: A fiber web is reeled by a reeling drum of a reel-up onto a parent roll. When the parent roll has reached the desired diameter size, reeling is changed from the parent roll onto a new parent roll. The web is cut by jet cutting means and the beginning part of the cut web is directed onto a reeling shaft of a new parent roll. The jet cutting path has a main cutting path and at least one edge area cutting path. The length of the main cutting path is at least 60% of the whole cutting path length from one edge of the web (W) to the other edge of the web (W). A turn-up device for a reel-up has one cutting module (15) and at least one nozzle (11) for jet cutting, which is attached movably and turnably to the module (15) by a cutting arm (12).
