  • Patent number: 11530515
    Abstract: The invention relates to a paper making machine (1) comprising a forming section (2) in which a fibrous web (W) can be formed, a drying section (5) in which a formed fibrous web (W) can be dried; and a reel-up (11) on which a dried fibrous web (W) can be wound into a roll (12). The paper making machine (1) is arranged to carry a fibrous web (W) in the machine direction (MD) along a predetermined path (P) and the paper making machine (1) has at least one water jet cutting device (17, 18, 19) arranged to cut the fibrous web (W) that is moving in the machine direction (MD) such that the fibrous web (W) is divided into at least one waste part (23a, 23b, 30) and a remaining part (24, 29). The paper making machine (1) is arranged to direct the at least one waste part (23a, 23b, 30) away from the predetermined path (P) and to convey the remaining part (24, 29) further in the machine direction (MD) along the predetermined path (P).

  • Publication number: 20210310191
    Abstract: The invention relates to a drying section and comprises one or more through air drying cylinders 3, 5 and a permeable fabric 9 that runs in a loop and wraps part of the circumference of each through air drying cylinder. The loop of the fabric 9 is divided in a web-carrying part 10 and a conditioning part 11. The web-carrying part extends from a receiving point 12 to a transfer point 15 where a fibrous web is transferred to a further component. The conditioning part extends from the transfer point 15 to the receiving point 12. The conditioning part has a cleaning section 19 comprising a shower 20 to wash residue from the fabric. A dewatering section 21 is arranged to act on the fabric 9 after the cleaning section and comprises one or several suction dewatering devices 22. An applicator section 23 is arranged in the conditioning part 11 after the dewatering section. The applicator section comprises an applicator 24 for applying release agent on the fabric 9.
