  • Patent number: 9347180
    Abstract: The invention relates to a device for dewatering a fibrous web with a press zone which is formed by a mating element with a curved surface and a permeable press belt which wraps at least partially around the curved surface and has a running side and a contact side contacting a second side of the fibrous web. A permeable carrier belt arranged between the mating element and the fibrous web guides the fibrous web through the press zone. The device is configured so a fluid can flow through the press belt, the fibrous web, and the permeable carrier belt at least in a part region of the press zone. The permeable press belt is configured to generate a pressing pressure in the press zone when a tensile stress of at least 20 kN/m is applied and the contact side is adapted to a quality of the fibrous web produced.

  • Patent number: 8440055
    Abstract: A pressing arrangement including at least one first fabric and second fabric both being permeable. A paper web is disposed between the first fabric and the second fabric. A pressure producing element is in contact with the first fabric. A support surface of a supporting structure is in contact with the second fabric. A differential pressure is provided between the first fabric and the support surface that acts on the first fabric, the paper web, and the second fabric, whereby the paper web is subjected to mechanical pressure and experiences a predetermined hydraulic pressure so as to cause water to be drained from the paper web. The pressing arrangement is structured and arranged to allow air to flow in a direction from the first fabric through the paper web and through the second fabric.

  • Patent number: 8303773
    Abstract: A method of producing a tissue paper web in a papermaking machine including the steps of forming the web on a skin, selecting a quality of the web, bypassing a dewatering apparatus, passing the skin and web through a nip and conveying the web to a drying cylinder from the skin. The web is formed in a forming section of the machine from a pulp suspension on the skin. In the selecting step a quality of the web is selected thereby defining a quality selection of absorbency or tear resistance. The bypassing step includes bypassing the dewatering apparatus with the web and selecting a type of the skin dependent upon the quality selection.

  • Patent number: 8070916
    Abstract: Method and device for producing a web of tissue. In the method, the web of tissue is led over at least one drying cylinder, doctored off the latter with a creping doctor and then wound up by way of a winding device. The web of tissue is supported at least largely over the entire distance between creping doctor and winding device on one side by a transfer device, so that there is only a short free web draw, while its other side is free. The device includes at least one drying cylinder, a creping doctor arranged on the drying cylinder and a winding device that winds up the web of tissue. Between the creping doctor and the winding device, a transfer device at least largely bridges the entire distance which supports the web of tissue on one side. There is a short free web draw, but its other side is left free.
