摘要:
A winding machine and process for winding a material web onto a reel. The material web is guided around a carrying drum, in which a nip is formed between the carrying drum and the reel. One of the reel and the carrying drum may be cyclically inclined in relation to a travel direction of the material web by a drive device or press device in order to achieve an axial changing of the material web in a winding roll.
摘要:
Apparatus and process for dewatering a material web. The apparatus includes at least one pressure chamber formed by at least four substantially parallel rolls, a device arranged to introduce a pressurized gas into the at least one pressure chamber, and the at least four substantially parallel rolls being displaceable relative to one another to change an effective area of the at least one pressure chamber. The material web is guided through the at least one pressure chamber. The process includes pressurizing at least one pressure chamber with a gas medium, guiding the material web through the pressure chamber, driving water out of the material web using gas pressure within the at least one pressure chamber, and changing an effective area of the pressure chamber so as to adjust a dewatering capacity.
摘要:
This invention relates to a system and a method for optimization of the process performance of a web-processing machine, in particular a machine for the production or further processing of paper, paperboard or tissue, including the following steps: storage of specific data of a component on a data storage unit fitted to the component; and/or measurement of relevant properties of the component by way of a sensor unit fitted to the component; sending of the specific data and/or the measured relevant properties to an open-loop control unit and/or a closed-loop control unit; and optimization of the process performance by way of the open-loop control unit and/or the closed-loop control unit using specific data and/or the measured properties of the component.
摘要:
Process and apparatus for winding a material web onto a reel spool to produce a wound reel. The process is performed in the apparatus and includes producing the material web, online smoothing of the produced material web, guiding the smoothed material web over a reel drum and through a nip formed between the reel drum and one of the reel spool and the wound reel, maintaining contact between the reel drum and the one of the reel spool and the wound reel, and reeling the smoothed material web while transversely moving at least one of the reel drum and the one of the reel spool and the wound reel relative to a web travel direction. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The apparatus includes a web production facility, an online smoothing device, a reel drum, and a reel spool. A nip is formed between the reel drum and one of the reel spool and the wound reel, and the reel drum and the one of the reel spool and the wound roll are arranged to maintain contact during a winding procedure. At least one device is arranged to move at least one of the reel drum and the one of the reel spool and the wound reel transversely to a web run direction.
摘要:
Device and process for removing a fibrous material web from a drying section of a machine for producing and/or refining the fibrous material web and into a catch device. The drying section includes heated drying cylinders, guidance rolls, and at least one drying wire arranged such that the fibrous material web is guided through the drying section over the heated drying cylinders and the guidance rolls at least predominately by the at least one drying wire. The device includes at least one controllable separating device arranged to at least reduce an adhesion force between the fibrous material web and the at least one drying wire.
摘要:
Process and apparatus for dewatering a fibrous material web. The process includes guiding the fibrous material web through a dewatering zone, and directing a plurality of gas pressure pulses of a pressurized displacement gas one after the other onto a surface of the fibrous material web within the dewatering zone. The apparatus includes a device for forming a plurality of gas pressure pulses which are arranged one after the other within the dewatering zone. The plurality of gas pressure pulses are directed onto a surface of the fibrous material web.
摘要:
Machine for producing a web includes a former for sheet formation of the web, a press section for dewatering the web, a drying section for drying the web, and at least one edge strip forming device positioned in an area of at least one of the press section and the drying section, which is arranged to separate at least one edge strip from the web.
摘要:
A sealing device and process for laterally sealing at least one overpressure zone or underpressure zone adjacent to an actuating surface in a paper-making machine. The sealing device has at least one sealing element arranged movably at least locally in an intake area of a support. The sealing element is loaded with a sealing or opposing force in order to place it against the actuating surface. A stopping element is fixed at a distance from the actuating surface which limits the seating motion of the sealing element.
