  • Publication number: 20070184955
    Abstract: Disclosed is a heated cylinder (1) for heating a paper web, cardboard web, tissue web, or another fiber web in a machine used for producing and/or refining the fiber web. Said heated cylinder (1) comprises a cylinder sleeve which is impinged upon at least in part from the inside by a hot fluid and is provided with at least one inner and an outer sleeve layer (5, 6). The inventive heated cylinder (1) is characterized in that the two sleeve layers (5, 6) are separated from each other by a hollow space into which the fluid can be introduced.

  • Patent number: 6303001
    Abstract: Process for homogenizing the property cross direction profile of a continuous web made of paper or cardboard and a paper machine that is suitable for carrying out the above-mentioned process. The process is characterized in that the shrinkage cross direction profile of the material web is homogenized during its manufacturing process by controlling the local composition of the stock suspension sectionally across the width by changing the proportions of components that have different shrinkage behaviors. The paper machine includes an approach flow system having at least two regions that produce different stock suspensions with fiber mixtures that have different shrinkage behaviors. The stock suspension supplies from the approach flow system to the headbox have at least two branches for the at least two different stock suspensions. Near the headbox, a plurality of sectional mixing points are provided, which combine the stock suspensions that have different shrinkage behaviors.

  • Patent number: 6189233
    Abstract: Dryer section of a machine for at least one of producing and processing a web of material. The dryer section includes at least one heatable drying cylinder having a circumference, at least a part the circumference adapted to be surrounded by the material web, at least one support band arranged to surround the at least a part of the circumference, and a sealing band arranged to surround the at least a part of the circumference. An overpressure cap is arranged to receive one of a liquid and gaseous medium and is adapted to apply a pressurized one of the liquid and gaseous medium on the at least one drying cylinder. A temperature of the medium is lower than a temperature on an outside of the part of the circumference. At least one second support band is arranged around the at least one drying cylinder and is positioned between the at least one support band and the sealing band, wherein the at least one second support band has a coarser structure than the at least one support band.

  • Patent number: 6098309
    Abstract: Apparatus and process for manufacturing or treating a material web that includes at least one heatable cylinder and a combustion unit. The combustion unit is adapted to heat the at least one heatable cylinder with at least one of combustion gases and infrared radiation and the material web is adapted to be guided one of alone and with a transport belt over the at least one heatable cylinder. The apparatus also includes at least one blower box positioned to direct a hot gas onto the material web. The hot gas is at least one of the combustion gas and heated by the combustion gases. The process includes heating the at least one heatable cylinder with at least one of combustion gases and infrared radiation of the combustion unit, guiding the material web, one of alone and with a transport belt, over the at least one heated cylinder, and directing a hot gas from the blower box onto the material web, the hot gas being at least one of the combustion gas and heated by the combustion gases.
