Definitions

  • the invention relates to stiffeners for a papermaking, paperboard or tissue making machine for mounting machine components, such as e.g. Rollers, suckers, cylinders, scraper plates or the like.
  • machines such as machines for making paper, board or tissue products are typically on-site, e.g. built in the paper mill.
  • foundations are cast with the appropriate mounting options for the machines.
  • the foundation parts or the machine frame are then built on this foundation.
  • the framing parts for the press section or dryer section for example, as well as most other components of a papermaking machine, such as scraper bars or drying cylinders, usually consist of a welded steel construction which is coated with a stainless steel protective layer or other protective protective layer for anti-rust purposes.
  • the individual parts of the machine are fixed to the parts of the frame, such as rollers, suction cups, cylinders, etc., all the machine parts necessary for the machine to function.
  • the document EP0020886A1 discloses a substructure for a web-fed rotary printing press.
  • the substructure consisting of a Very twinungs-, paper drive, paper feeding and paper changing support frame, on the head side, a printing unit is mounted, the frame of the base is made of reinforced concrete.
  • this concrete frame an externally prefabricated metal frame with several, at least partially exposed to the outside support elements such as metal plates or the like is formed, on which support elements the Textilhalterungs-, Pandaantriebs-, Piezu Switzerland- and paper changing facilities, optionally also other units

It is a sheet metal used, which remains on the finished machine part and determines its outer shape. During the introduction of the concrete in the shape determined by the metal skin and in particular during the compaction of the concrete, the metal skin is on its outside over the entire surface by means of a flowable or free-flowing medium, preferably sand, supported. The metal skin not only forms an outer protection for the concrete but also serves as a structural part for absorbing tensile forces in the operating state. To produce the machine parts, the shape formed by the metal skin is suspended in a molding box with all-round spacing and supported by means of a flowable or free-flowing mass. The molding box is placed on a vibrating table.

  • the still moist fibrous web 12 in a drying section 18 with in a row next to each other transferred drying cylinders 19 and dried under Neander run around the heated drying cylinder 19.
  • the fibrous web 12 now an already dry fibrous web, passed through a calender 20 to a winding device 21 and wound there to form a winding roll 22. All components or assemblies of the machine such as rollers, suction cups, cylinder scrapers, and the like are attached to the Funging parts.
  • a framing part 3 according to the prior art is shown.
  • the stiffening part 3 is designed as a welded construction, which has a cavity inside.

After alignment, the remaining space between the stiffening part 3 and the foundation 6 can be poured out with a filling foundation layer 7.
  • connecting flanges 2 or threaded inserts 9 are cast in the support body.
  • To obtain a level bearing surface 10 of the concrete is ground in the appropriate places.
  • the support body 1 can take over the function of the stiffening this is made of ultra high-strength concrete. This achieves a compressive strength of up to 800N / mm 2 and requires no steel reinforcement in the conventional sense, but contains for strain relief steel or polypropylene fibers. This makes it very easy to produce the various forms of the framing parts, without first having to pour a reinforcing grid with the appropriate shape.
