Definitions

  • the present invention relates to an arrangement for treating a paper, board, tissue or other fibrous web in a machine for producing and/or finishing the same, the arrangement including an endlessly circulating belt with a high flexural rigidity which wraps around a rotatably mounted control roll with a wrap angle, at least one end of the control roll being mounted such that it can be displaced along an adjusting travel in order to set the belt tension.
  • Control rolls of this type have been known and are intended to influence the belt run with regard to limiting the lateral run-off of the belt parallel to the roll axis.
  • the present invention provides an arrangement for treating a paper, board, tissue or other fibrous web in a machine, the arrangement including an endlessly circulating belt which wraps around a rotatably mounted control roll having a wrap angle lying between 90° and 180° and the adjusting direction of the control roll lying approximately perpendicular to the bisector of the wrap angle.
  • the wrap angle corresponds to the difference between 180° and the angle between the belt running on and running off with regard to the control roll.
  • higher frictional forces can also be transferred to the belt, which sharply reduces the risk of the belt sliding on the control roll.
  • the linear adjustment of the mounting approximately perpendicular to the bisector minimizes the change in the belt length and thus, the increase in stress associated with the latter.
  • the angle between the adjusting direction and the bisector may lie between 60° and 120°, between 80° and 100° and between 85° and 95°.
  • the adjusting travel may be at most 60 mm long.
  • both bearings of the control roll may be adjusted or else only one bearing may be adjusted and the other remain fixed. In the event that both bearings are adjusted, the bearings should be adjusted in opposite directions.
  • the arrangement of the present invention may be suitable for belts of which the modulus of elasticity is greater than 100 kN/mm2, or greater than 190 kN/mm2. Furthermore, for the same reason the arrangement of the present invention may be suitable for belts which are wider than 2 m and/or have a thickness of more than 0.5 mm or more than 0.8 mm.
  • the belt in the arrangement of the present invention may be formed as a steel belt and may also be impermeable.
  • the belt of the arrangement of the present invention may be pressed by a pressure element against a supporting element running with it, and the fibrous web, on its own or together with one or more functional belts, may run between the supporting element and the belt.
  • the pressure element may be formed by a stationary pressure chamber filled with a pressurized fluid, the pressure chamber being open toward the belt and sealed off with respect to the belt.
  • the supporting element should be formed by a rotating supporting roll.
  • the control roll should be arranged before the supporting roll, the length of the belt from the control roll as far as the supporting roll being less than one third less than one quarter of the overall belt length.
  • control roll or the guide roll may have a roll cover, which may be a rubber cover, with high friction, preferably with a ⁇ of more than 0.2.
  • a roll cover which may be a rubber cover, with high friction, preferably with a ⁇ of more than 0.2.
  • improved adhesion is achieved if the roll cover has grooves. In this case, the grooves should run axially parallel or with a herringbone geometry.
  • FIG. 1 illustrates a schematic cross section through the arrangement of the present invention.
  • FIG. 1 there is shown a drying arrangement of a paper machine for drying fibrous web 1 .
  • supporting element 8 in the form of a cylindrical, rotating and heated supporting roll and impermeable, endlessly circulating belt 2 wrapping around the supporting roll.
  • two water-absorbing functional belts (not shown) are guided through the press nip formed by belt 2 and the supporting roll, running between fibrous web 1 and belt 2 .
  • pressure element 9 in the form of a pressure hood, having a pressure chamber filled with fluid.
  • This pressure chamber is sealed off with respect to belt 2 by seals, so that the fluid of the pressure chamber, open toward belt 2 , presses belt 2 toward the circumferential surface of the supporting roll.
  • Cooling of belt 2 is carried out by the fluid, so that intensified condensation occurs in the water-absorbing functional belts. In this way, the water evaporated from fibrous web 1 via the heating by the supporting roll can be led away simply via the functional belts.
  • belt 2 Before and after the pressure hood, belt 2 is pressed against the supporting roll by guide roll 10 in each case. This leads to the compression of the nip between belt 2 the and supporting roll and improves the guidance of belt 2 and the functional belts.
  • the seal with respect to belt 2 must be lubricated. It is carried out here via leakage of the fluid, water here, from the pressure chamber.
  • Thermally conductive belt 2 is formed by a steel belt, which has a width of several meters and a thickness of 0.8 mm.
  • the modulus of elasticity of belt 2 is more than 200 kN/mm2.
  • belt 2 is led around control roll 3 that is rotatably mounted on both sides and is arranged before the supporting roll.
  • Wrap angle 5 of belt 2 is around 140°, it being possible for both bearings of control roll 3 to be displaced over adjusting travel 7 . In this case, wrap angle 5 corresponds to the difference between 180° and angle 12 between the belt running on and running off with regard to control roll 3 .
  • the adjusting direction of the mountings of control roll 3 is approximately the same as perpendicular 6 to bisector 4 of wrap angle 5 .
