  • 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: 10364113
    Abstract: The invention relates to an apparatus for winding a paper web. It comprises a rotatably mounted reel spool (3) onto which paper can be wound and an endless flexible belt (5) which is permeable to air and supported by support rolls (12). The flexible belt is positioned adjacent the reel spool (3) to engage the web against the reel spool during winding such that the endless flexible belt is deflected from the path of travel. The flexible belt has a web-contacting side (6). An actuator (9) is arranged to position the reel spool (3) and the flexible belt relative to each other to vary the amount of deflection. The apparatus further comprises a cleaning device (11) with at least one nozzle for blowing air against the web-contacting side of the flexible belt at a point where the flexible belt is not in contact with the paper. The invention also relates to a method of removing dust particles.

  • Patent number: 9828201
    Abstract: The invention relates to a reel-up (1) for receiving and winding into a roll (5) a paper web (W) that arrives from a drying cylinder (2) in a paper making machine. The reel-up (1) comprises a rotatably mounted reel spool (4) onto which a paper web (W) can be wound to create a paper roll (5) of increasing diameter and an endless flexible belt (6) mounted for rotation along a predetermined path of travel such that the flexible belt (6) forms a loop. The flexible belt (6) is positioned adjacent to the reel spool (4) to engage the paper web (W) against the reel spool (4) during winding such that the flexible belt (6) is deflected from the predetermined path of travel when the paper roll (5) starts to build up on the reel spool (4). The flexible belt (6) is air permeable and at least one blow box (7, 8, 9) is arranged inside the loop of the flexible belt (6) such that an underpressure can be generated that draws the paper web (W) against the flexible belt (6).

  • Patent number: 9464309
    Abstract: According to a first aspect, hydrolysis of a protein-containing raw material and separation of amino acids/peptides is carried out, wherein the hydrolysis is effected by using the endogenous enzymes of the protein-containing raw material. The hydrolysate is passed through a membrane filter, wherein peptide/amino acids follow a permeate stream, while the active enzymes continuously break down any protein residues that are deposited on the membrane surface. The enzymes are passed together with retentate back to the hydrolysis. Furthermore, an amino acid and peptide product and an oil product are described and the use thereof is disclosed.
