摘要： A coating device where the pressurized coating space formed between the doctor element and the material web and/or the counter roll carrying it is defined by a regulating plate on the inlet side relative to the material web. A guide device is so arranged in the coating space that coating mixture will circulate around it on all sides in one direction of rotation. The guide device generally leaves only relatively narrow flow channels open in the coating chamber so that harmful turbulent flows are extensively avoided which through pulsating air inclusions might lead to defects in the applied coating.

摘要： Apparatus for applying a liquid coating onto a moving web has one or preferably two rotatable rollers. In the two roller embodiment both rollers lie on the same plane which is at or near the horizontal. The two roller embodiment positions the rollers adjacent each so as to form a press nip between them. The moving web makes contact with one of the rollers, or the single roller along an extended circumferential arc of the roller. Adjacent each roller is a supply apparatus for depositing a liquid on to a portion of the roller jacket not in contact with the web. Wiper rods are associated with each supply apparatus and are biased against the jacket of the roller to make the coating of liquid uniform. Surplus liquid is used to wash the rollers to remove web fibers and glue and pigment particulate to avoid contamination thereby of the supply apparatus and wiper rods. The surplus liquid and fibers and particulate are collected in sumps.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Apparatus for stabilizing the trailing end of a web that is to be spliced to the leading end of a new web includes a knife for severing the old web and for creating a tail that must be stabilized, a suction box over which the trailing end passes, which provides stability to the trailing end, a pressure roll movable to move the cut trailing end of the old web against the leading end of the new web and a leaf-spring-like extension extending downstream of the suction box to the connection point or splice point between the webs. The extension is deflectable with the pressure roll and the extension carries the vacuum of the suction box further downstream and also supports the trailing end of the cut old web. The extension is cantilevered to the downstream side of the suction box.

摘要： In a method for direct or indirect application of a liquid or pasty medium onto a traveling material web, notably of paper or cardboard, where during the application the cross profile (length profile) of the medium is modified under control and thereafter, in the direction of travel, the length profile (cross profile) of the previously applied medium is modified under control. Control of the cross profile and control of the length profile of the applied medium occur separately from one another in automatic control loops based on measurements of the applied profile. In addition is a pertaining apparatus with an applicator, an equalizer, a pertaining cross profile control loop, and a pertaining length profile control loop.

摘要： 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.
