Definitions

  • the invention relates to a roll shell for a smoothing or press roll Treatment of a material web, especially for dewatering a paper, Cardboard, tissue or other fibrous web in a press nip Machine for the production of the fibrous web whose ends with a roller axis are connected and with a layer of elastomeric material in which for Reinforcement embedded threads running lengthways and crossways to the web running direction are.
  • Such roll shells have been known for a long time and are particularly used in Shoe press rollers used. There they are subject to the concave pressing surface to form an extended press nip of a permanent deformation. With increasing machine speed results in considerable Wear and tear sensitivity requirements.
  • the object of the invention is therefore the stability and wear resistance of the Roller shell without significantly impairing its suitability and with to improve reasonable effort
  • the object was achieved in that at least sections of at least one layer of additional reinforcing threads in the Layer is embedded, the reinforcing threads at an angle between 20 ° and run 70 ° to the web running direction.
  • the threads running lengthways and crossways to the web running direction should be advantageous form at least one separate layer each. Manufacturing advantages arise if at least one layer each of longitudinal and transverse to Threads running from a fabric is formed. to Influencing the torsional stiffness can also be advantageous if at least two layers of approximately longitudinal and transverse to the web running direction Threads are viewed radially from each other.
  • the load and the type of reinforcement can the layers of the additional reinforcing threads outside the in and across Path running threads and / or between in and across Threads running web direction. They are preferred additional reinforcement threads between two layers of in and / or across Threads running web embedded, the threads and Reinforcing threads preferably have similar strength.
  • the additional reinforcement threads only in one or more, preferably axially limited sections of the Roll shell are present. Because of the particularly high stress the ends of the roller shell and the center thereof can be used.
  • the reinforcing threads or the corresponding fabric are advantageously used during the casting of the roll shell from an elastomeric material.
  • roller jacket can also have blind bores for water absorption.
  • the roller shell is essentially of a layer 1, as can be seen in FIG. 1 made of elastomeric material, for example polyurethane, in which a layer of threads 2 running in the direction of web travel 5 and threads 3 running transversely thereto is embedded. These threads 2, 3 provide the required roll jacket Dimensional stability without the deformability in the area of the press nip affect.
  • the outside of the roller shell has, for example, approximately Web running direction 5 extending grooves 6 for receiving the squeezed water.
  • the roller shell is driven by the opposite cylindrical one Press roll of the press nip. Because the roller jacket at the ends over Side shields are rotatably mounted on the roller axis, must also in the general metallic side shields accelerated over the roller jacket or be slowed down. This torque causes in the roll shell Shear stresses whose direction of action is ⁇ 45 ° to web running direction 5.
  • layer 1 also contains two perpendicular to each other and each 45 ° to the web running direction 5, additional reinforcement threads 4 according to FIG. 2.
  • These reinforcement threads 4 are constructed exactly like the other threads 2, 3.
  • the reinforcing threads 4 are producible and have high torsional rigidity over the other threads 2, 3, that is arranged outside of them.
  • the better torsional stiffness has a positive effect on wear and especially for wear.
  • Figure 3 shows a roll shell in which the mutually perpendicular Reinforcement threads 4 are formed by a fabric tape, which together with the threads 2 oriented in the direction of web travel 5 spirally in the roll shell runs.
  • the edges of the band 7 overlap such that the in Web running direction 5 running threads 2 are covered on both sides by the tape 7.
  • the band 7 has a width between 5 and 50 mm, the reinforcing threads 4 run inclined to the winding direction and preferably the same angular amount form to the winding direction.
