Definitions

  • the present invention relates to a method for manufacturing a press jacket made of flexible material for one Press device for dewatering a material web in one Press nip, in particular for shoe presses for papermaking, with essentially extending in the circumferential direction Grooves in at least one surface of the press cover and reinforcement threads embedded in the sheath material, at least some of which are essentially circumferential of the press cover extends. Also concerns the invention a manufactured by this method Press jacket.
  • Press sleeves with circumferential grooves in the outside of the press sleeve are already known.
  • the circumferential grooves serve the Absorb water and improve drying properties of the press jacket in a dry press.
  • Through the Circumferential grooves will increase the risk of cracking Press jacket enlarged because the jacket material in the area of Grooves is weakened. To make matters worse, Spread and enlarge any cracks along the grooves can.
  • reinforcing threads in the jacket material is also known.
  • the reinforcing threads are used to To increase the tensile strength of the press jacket, since this in particular exposed to very high tensile forces in shoe presses is, which can lead to breakage of the press jacket.
  • Next reinforcing threads running in the circumferential direction also reinforcing threads running in the axial direction of the press jacket be provided.
  • the invention has for its object a method for Production of a press jacket of the type mentioned and a press jacket made by this method specify which is characterized by great durability and strength distinguished. In particular, the risk of crack formation be reduced.
  • This object is achieved in that the Distribution of the grooves over the surface of the press jacket depending on the distribution of the circumferential direction extending reinforcing threads is chosen such that the Grooves and the reinforcement threads also not in sections run radially one above the other and in the same direction.
  • the method according to the invention eliminates the risk of Cracking in the area of the circumferential grooves significantly reduced. It was found that the risk of cracking is greatest where circumferential grooves are essentially run in the same direction as that in the jacket material arranged reinforcement threads The reinforcement threads namely also represent a weakening of the jacket material since it is similar to the circumferential grooves as a notch act and increase the risk of cracking. This risk of cracking is particularly worrying because any cracks that develop quickly along the bottom of the groove spread the entire circumference of the press jacket around and thereby the risk of the press casing bursting is very great becomes.
  • the grooves on the one hand and the reinforcing threads on the other hand with each other different angles of inclination to the circumferential direction introduced into the press jacket Due to the different angles of inclination the circumferential grooves and the reinforcing threads it is guaranteed that not even in sections circumferential grooves and reinforcing threads radially in the press jacket on top of each other and in the same direction, so a double weakening of the press jacket material occurs.
  • circumferential grooves and reinforcing thread also introduced with the same inclination in the press jacket if care is taken to ensure that the circumferential grooves and the reinforcing threads are axially offset from one another. Due to different angles of inclination Risk of cracking is further reduced because the assignment between the circumferential grooves and the reinforcing threads in the direction the press jacket axis varies.
  • the grooves with a larger angle of inclination are preferred introduced into the press jacket as the reinforcing threads.
  • the grooves with an angle of inclination introduced which is at least three times the size of the Reinforcement thread angle of inclination. This configuration has been designed for both preventing cracking as well for the strength of the press jacket as particularly advantageous exposed.
  • the distances between the grooves on the one hand and the Spacing of the reinforcing threads on the other hand chosen so that they do not have a common, integer multiple.
  • the grooves are spaced apart introduced into the press jacket from each other, the at least is approximately 1.15 times the distance between the reinforcing threads from each other. This configuration has changed turned out to be particularly advantageous.
  • the circumferential grooves can be closed as annular grooves be introduced into the press jacket.
  • Another one Embodiment of the invention can the circumferential grooves but also in the form of a around the longitudinal axis of the press jacket running screw line introduced into the press jacket will.
  • the reinforcement threads can be closed as a ring Reinforcing threads and as around the longitudinal axis of the Press jacket extending screw line in the press jacket be introduced.
  • the reinforcement threads can be closed as a ring Reinforcing threads and as around the longitudinal axis of the Press jacket extending screw line in the press jacket be introduced.
  • the reinforcement threads can be closed as a ring Reinforcing threads and as around the longitudinal axis of the Press jacket extending screw line in the press jacket be introduced.
  • a single reinforcement thread helical be introduced.
  • two or more reinforcement threads helically in the Press jacket are introduced.
  • the reinforcing threads thereby in the form of a multiple screw line brought in.
  • Distribution of the reinforcing threads in the one above the other radial layers of the press shell selected so that reinforcement threads also not in sections in the press jacket run radially one above the other and in the same direction. This configuration in turn ensures that the press jacket has no multiply weakened sections, in which the risk of cracking is particularly high.
  • the reinforcing threads running in the circumferential direction also extending in the axial direction of the press jacket Reinforcing threads introduced into the press jacket material.
  • the axis threads preferably run radially inner layer of the press jacket than that Circumferential threads. Basically, the circumferential threads can also be introduced radially further inside.
  • circumferential grooves 1 are in a conventional press jacket a plurality of circumferential grooves 1 over the press jacket 2nd distributed.
  • the circumferential grooves 1 can be annular Endless grooves or as helical around the longitudinal axis the press jacket 2 arranged grooves formed be.
  • the reinforcing threads running in the circumferential direction are not radially below the circumferential grooves 1.
  • the circumferential direction 6 of the press jacket 2 is inclined in opposite directions. That is, the circumferential grooves 1 form an angle ⁇ R with the circumferential direction 6, which has an opposite sign to the angle ⁇ UF , which the reinforcing threads 4 enclose with the circumferential direction 6.
  • the amount of the angle ⁇ R is also greater than the amount of the angle ⁇ UF .
  • the circumferential grooves 1 thus run at a greater angle of inclination to the circumferential direction 6 than the reinforcing threads 4.
  • the opposite sign of the respective inclination angles ⁇ R and ⁇ UF ensures that the press jacket 2 has no cross-sectional planes in which the circumferential grooves 1 and the reinforcing threads 4 also run radially one above the other only in sections in the same orientation. A double weakening of the press jacket 2 is thereby avoided.
  • the circumferential grooves 1 and the reinforcing threads 4 run with the same inclination to the circumferential direction 6.
  • the amount of the inclination angles ⁇ R and ⁇ UF is different.
  • the angle of inclination ⁇ R of the circumferential grooves 1 is namely larger, in particular chosen at least three times as large as the angle of inclination ⁇ UF of the reinforcing threads 4. This also ensures that the press jacket 2 does not have any cross-sectional planes in which the circumferential grooves 1 and the reinforcing threads 4 also only run in sections in the same direction. In this variant, too, there are therefore no doubly weakened sections of the press jacket 2.
  • circumferential grooves 1 and the reinforcing threads 4 can also do so axially offset from one another over the circumference of the press casing 2 distributed that no cross-sectional planes of the press casing are present, in which circumferential grooves 1 and reinforcing threads 4 only in sections run in the same direction. Rather are in the cross-sectional levels either only circumferential grooves 1 or only reinforcing threads 4 available.
