    Abstract: A drying section for a paper making machine. The drying section includes a plurality of single-tier dryer groups, optionally followed by one or more double-tier groups. To control curl in the final paper product, a moistening device extending over the width of the drying section is provided near the end of the single-tier dryer groups. The moistening device can be divided into various zones to control the profile of the paper. Alternatively, or in addition to the moistening device, a contact-less dryer such as a infrared dryer can be provided after the dryer section, upstream of a calendar section of the paper making machine. The moistening device can be provided to moisten the bottom or, optionally, the top side of the paper web. Where a double-tier dryer group is provided, to control curl the upper drying cylinders and the lower cylinders can be provided with different steam pressures to control curl. Alternatively, each of the cylinders can be individually controlled.

    Abstract: A wire part of a machine for the production of continuous fibrous material webs, especially a papermaking machine, includes two continuous wire belts which together form a twin-wire zone. At least one supporting element having a supporting surface is disposed in the region of the twin-wire zone. At least a part of the supporting surface provides a supporting region which supports a first wire belt on its inner surface and a second wire belt on its outer surface. At least one formation box is provided and is disposed in the supporting region. The formation box is designed in such a way that, in the region of the inner surface of the second wire belt in the formation box, pressure values can be adjusted from a reduced pressure to an excess pressure acting on the inner surface of the second wire belt. The formation box extends in the direction of movement of the wire part over at least a part of the supporting region.

    Abstract: A winding machine for winding a traveling web of paper or the like. A carrying drum extends across the web. A first pair of primary levers supports the pins at the end of a cylinder on which the web is to be wound. The primary levers have one end with a fork for receiving a respective journal pin of the cylinder and another end that is mounted in the region of but eccentric to the axis of the carrying drum. The primary levers swing the cylinder over approximately 90.degree. around the carrying drum to a second position. A second pair of secondary swing levers pick up the cylinder at the second position and move it to a third position along a substantially horizontal second pathway. A first drive connected with one primary lever introduces a moment of rotation to the axis of the cylinder moving along the primary path. A sensor detects the radial position of the cylinder and a setting device adjusts the radial position of the first drive in order to align it with the cylinder. There may be a secondary drive for imparting rotation to the cylinder over the secondary path.

    Abstract: A hollow cylinder exhibits an internal body, which forms a sickle-shaped space by means of a partial cylindrical surface arranged eccentrically to the hollow cylinder, with a smaller radius than its internal radius. In this space there is created a vacuum on rotation of the hollow cylinder. By This means air is sucked out of the area through the boreholes of the hollow cylinder, where a web of material wraps the hollow cylinder. This leads to a firmer adherence of the web on material to the hollow cylinder.

    Abstract: There is provided a coiling machine for coiling a continuous paper web having two large rolls that form a coil bed for uptake of a paper coil. The space bounded by the large rolls and the coil is formed as a pressure-tight chamber that has a compressed air connection. Particularly for the present invention, one of the two large rolls has a jacket that is essentially more intensely deformable than the jacket of the other roll and, thus, one large roll is softer than the other large roll. The upper vertex of the softer large roll is located lower than the upper vertex of the harder large roll. The web guidance is configured for one embodiment of the coiling machine such that the web is introduced from below, and between the two large rolls, to wind around the softer large roll. For another embodiment of the coiling machine, the web is introduced through a pressing gap between one of the large rolls and the coil.

    Abstract: In a process for the coating of a running web of paper or cardboard, provisions are that in a press gap formed between two rolls a coating substance applied in a very small quantity on the surface of the one roll is first pressed on the web leaving a very thin coat on the web which, however, covers all spots including the "mounds" of microroughness. Next, the second coat can be applied and dosed on the still moist first coat with the usual means. In the process, the first coat is preferably dosed on the shell of the first roll, by means of the peripheral grooves of a rotary doctor. The same may be performed also as regards the second coating on the web.

    Abstract: A dry end of a paper making machine has a plurality of dryer groups each in turn comprised of a plurality of heatable dryer cylinders which alternate with reversal rolls. A respective support belt meanders past each dryer cylinder and the succeeding reversal roll in each dryer group. The web to be dried is supported on the side of each support belt to contact the heatable dryer cylinders. The reversal roll that precedes the first dryer cylinder in each succeeding group serves as a web removal roll which is wrapped by the second support belt of the succeeding dryer group. The first support belt of the preceding dryer group has the web on the side of the first belt which is toward the removal roll. The first support belt contacts the second support belt on the removal roll over a smaller part of the circumference of the removal roll than the second support belt. The removal roll transfers the web from the first support belt to the second support belt at the removal roll. There is an unsupported length of the first support belt from the last reversal roll of the first dryer group to the removal roll in the second dryer group that is of a length that the time of travel of a point on the first support belt between those two rolls is at least 0.05 seconds and preferably between 0.06 and 0.12 seconds. That zone is free of suction devices. The first support belt and possibly the second or preferably porous dryer wires. A boundary air layer deflection device opposite the removal roll deflects the boundary layer of air through the first support belt to help deflect the web off the first support belt onto the second support belt at the removal roll.
