Definitions

  • the subject of the invention is a device for clamping and sealing the edges of blanket of the press roll from the closed type extended nip presses, used for dewatering of product web in paper industry.
  • Extended nip presses are equipped with conventional press roll or controlled crown roll and pressing unit with stationary, profiling shoe. Web of paper is most often led on press felt, which is protected from the shoe's side by a movable blanket, moving on its surface with the same speed as felt and produced web. A liquid, preferably oil, is pumped between the working surface of the shoe and blanket, to create a lubricating film, protecting blanket as well as shoe from too early wear. Blanket is oil-proof and non-permeable for liquids.
  • Blanket edge clamping module and protecting the extended nip press roll from oil leaks is a crucial element of this device.
  • the module design should provide an effective clamping of blanket edges and required tightness of the connection as well as the facility to assemble and disassemble it.
  • the preliminary setting of the blanket edges has been realized through stretching on pins in a known way and the clamping is supported through a band, preferably metal, and corrugated, situated between blanket edges and the internal surface of the external sleeve.
  • the device has the sealing ring 1 situated on the rotating sleeve 2 between the internal shield 6 and external shield 7. External sleeve 8, equipped with pins 9, is fastened to the external shield 7. On the internal surface of the sleeve 8 the corrugated ring 10 is located.
  • the solution allows to effectively fasten the blanket edges and seal the roll from oil leaks, as well as to facilitate the disassembling of the roll unit because the unloading of the shields results in separating of the sealing ring from the blanket surface automatically.
