Definitions

  • the invention relates to a roller and the use of a roller for treating a paper or board web, with a fixed axis and a circumferential jacket, the at least one substantially axially extending in the roller, acting with a concave, hydrostatically lubricated contact surface against the jacket pressure shoe and a strip element arranged in front of it in the direction of rotation of the jacket which, with at least one support element, applies substantially radial forces against the jacket.
  • the invention relates to a method for treating a paper or board web with said roll.
  • rollers are in use which have a fixed axis. On this axis, at least one contact shoe is supported, which can be hydraulically pressed against a revolving pliable jacket. To avoid wear, the contact surface of the contact shoe, which acts against the jacket, hydrostatically lubricated. Hydrodynamic lubrication, as known from press rolls, is no longer sufficient at the higher pressures in the calender. In general, the jacket is therefore hydrostatically pressed against a counter-roller, which is usually heated. Between the jacket and the counter roll, a running paper or board web is subjected to pressure and temperature and thus satined.
  • the contact surface of the pressure shoe is often concave on the jacket and adapted to the contour of the counter roll.
  • Such a roll is marketed by the applicant under the name NipcoFlex roll.
  • a similarly constructed roll is used as a press roll for dewatering a paper or board web. Due to the low pressure forces a hydrostatic lubrication is not necessary.
  • the press roll also has a pliable jacket made of a material with an E-modulus of less than 1000 MPa. In general, a fabric (wire, felt) runs with the web through the nip to absorb the moisture. Exemplary here is the DE 196 15 654 A1 called, in which the jacket runs in a preferably convex portion of the Anpressschuhs on this.
  • Such a press roll for dewatering which has in the circumferential direction of the jacket in front of the concave-shaped pressure shoe, a jacket-supporting strip element.
  • the strip member serves to run the jacket at an angle in the nip, which ensures a hydrodynamic lubrication on the pressure shoe.
  • the DE 69524160T2 EP-A-0698684 discloses such a shell (reference numeral 11) with the main component epoxy, which, as clearly seen, but its convex Retains shape during the course of treatment.
  • the jacket of the counter-roller (reference numeral 31), however, is made of a softer material and can be concavely deformed. Accordingly, the epoxy jacket does not have to endure any higher pressures than the pliable jacket of the illustrated shoe roll.
  • the nip would not be longer than 25 mm for paper roll diameters (greater than or equal to 600 mm).
  • the hydrostatic lubricating film would most likely tear off.
  • the roller according to the invention in that the strip element is pressed against the jacket so that the jacket runs tangentially on the concave, hydrostatically lubricated contact surface acting against the jacket contact shoe and rests against the counter roll, so that the loads on the Sheath in the inlet area of the pressure shoe not more than 10% larger than in the contact shoe center and the sheath material has an average modulus of elasticity above 4000 MPa.
  • the convex and concave radii of curvature of the jacket are, in absolute terms, not less than 50% of the radius of curvature which the jacket has in the unloaded state.
  • the jacket is still deformed as before. But it holds the deformation in limits, in which the total burden of Mantels is as small as possible.
  • the mantle is deformed outwards (convexly) beyond only part of its circumference radially beyond the cylindrical shape which it occupies in the unloaded state. In another part, it is deformed radially inwards (concave).
  • the compressive and tensile loads are then distributed so evenly that the load overall remains relatively low. However, the burden can not be completely eliminated.
  • a maximum deformation of the jacket radially outward corresponds to a maximum deformation radially inwards.
  • the maximum deformation is the smallest radius of curvature that the jacket has. This smallest radius of curvature is the same in the convex shape as in the concave shape. This achieves a deformation equilibrium in which the load on the rotating jacket is relatively low.
  • the jacket is made up of at least three layers.
  • a jacket with a running layer for example made of epoxy or metal
  • a reinforced intermediate layer for example made of epoxy or metal
  • a functional layer for example, epoxy, epoxy, and a functional layer (Epoxy), which exerts pressure on the paper or board web, is particularly durable.
  • the jacket consists at least partly of metal.
  • a metal shell is composed in this case of a flexible sheet metal. Like the plastic sheath, it is sealed to end plates at the ends of the roller.
  • a metal shell has positive properties in the treatment of various types of paper and board because it can be cooled or heated. In addition, it may be longer lasting and must be reground less frequently.
  • the strip element also has a hydrostatic lubrication. As a result, the wear of the shell is reduced.
  • hydrostatic pressure pockets may be provided on the surfaces facing the jacket, which are supplied with lubricant radially from further inside the roller.
  • the roller comprises a second strip element arranged in the direction of rotation of the jacket behind the contact shoe.
  • the object of the invention is achieved in that the strip element is pressed against the jacket with such high pressure that the jacket, which has a jacket material with an modulus of elasticity above 4000 MPa, tangentially to the concave, hydrostatically lubricated contact surface of the acting against the jacket pressure shoe runs and abuts against the counter roll, so that the loads on the jacket in the inlet region of the pressure shoe maximum 10% greater than in the middle area of the contact shoe.
  • a simple measure can be taken to ensure that a jacket with a jacket material whose modulus of elasticity is above 4000 MPa can come into contact with a counter-roller at a significantly higher pressure than can be achieved without the adjustment of the strip element let alone be done with a jacket whose shell material has an E-modulus below 1000 MPa.
  • the loads in the input and in the center of the contact shoe are of course considered in the circumferential direction.
  • the strip element is subjected to pressure via a plurality of axially distributed support elements.
  • this offers the possibility of a uniform and relatively large force application, for example via pressure cylinders, on the strip element.
  • pressure cylinders for example, to press an epoxy coat to the outside, large forces are required compared to coats of presses or wide-nip calenders.
  • the object of the invention is achieved in that the roller, which has a jacket material with an E-modulus above 4000 MPa, is used in a calender for calendering.
  • a calender In contrast to a press, a calender is designed to be able to exert a high pressure on the web, in particular for high-quality papers, and thus to smooth the web accordingly. When Satinage but also the gloss of the web is increased. Both contribute to the later printability.
  • the surface roughness of the shell of the roll is below a Ra value of 0.3 ⁇ m. In this way, not only the web page, which rests against the smooth and heated counter roll, smoothed, but there are sufficiently good smoothness results also on the web side, which rests on the roll side.
  • a roller 1 is disclosed, which is installed in a calender 21.
  • the shell 5 of the roller forms outside a contact surface with the outer periphery of a heated counter-roller 2.
  • a paper web is subjected to pressure and temperature during operation and smoothed in this way.
  • the jacket 5 is fastened at its ends in a manner not shown, the expert but known manner to one end washer lubricant seal. It can be made of a composite of several layers of plastic Arm michsgeweben or alternatively consist of metal in at least one layer. Both types of material can also be combined. In any case, the average modulus of elasticity of the sheath material should be greater than 4000 MPa.
  • a pressure shoe 6 with a concave curved contact surface 7 exerts a force on the jacket 5 in the direction of counter-roller 2.
  • a pressure is built up on a piston 12.
  • the cylinder 8 is supplied with pressure medium, which is also lubricant at the same time.
  • pressure medium which is also lubricant at the same time.
  • the contact shoe may well be connected to a plurality of pistons 12. The lubricant generates when passing from the pressure pocket 9 on the entire pressure surface 7, a sliding pad to the jacket 5. A material wear both from the pressure surface 7 and the jacket 5 is largely avoided.
  • a strip element 13 is arranged in the roller. Here, the direction of rotation 22 of the shell 5 is observed. Also, this strip element is pressed as the pressure shoe via a support member 15 which is formed for example from a piston-cylinder unit, radially against the mantle. Likewise, a hydrostatic lubrication 20 may also be provided here. A second, possibly identical strip element 14 may be arranged behind the contact shoe.
  • the pressure surface 7 of the pressure shoe has an inlet region 16 and a central region 17.
  • FIG. 2 shows the difference of the pressure curve above the pressure surface 7 on the jacket 5 in a comparison with and without strip element.
  • Curve A shows the compressive stress (p) over the pressure surface (length b) when the strip member 13 and the second strip member 14 exert no pressure on the jacket. It can be seen especially in the inlet area a particularly high voltage peak. The sheath material would be damaged in a relatively short time.
  • Curve B shows the voltage curve when using the strip element with an optimally adjusted contact force. The use of the strip element causes the jacket to be brought tangentially to the concave contact surface, so that it does not have to "tip over" the edge of the inlet region 16 and abuts the counter-roller 2. The voltage curve remains almost straight after its rise and at the same level until it drops again at the end of the contact surface (b). The jacket 5 is thus claimed much less, although it is from the pressure level ago, about 15 N / mm 2 .
  • the contact force is then optimally adjusted when the jacket 5 is brought tangentially to the concave pressure surface 7 of the Anpressschuhs 6 and additionally the convex and concave radii of curvature 18 of the jacket 5 in operation absolutely considered not less than 50% of the radius of curvature 19, the coat in the unloaded condition.
  • the radius of curvature 19 of the unloaded roller is substantially equal over the entire circumference and defines a circle.
  • the kugradungsradium 18 is due to the pressure of the contact shoe and the strip elements anywhere on the circumference of the shell differently.
  • the smallest radius of curvature 18, namely between the strip element 13 and the pressure shoe 6, is 435 mm.
  • the jacket 5 is subjected to particularly little stress when a maximum deformation of the jacket 5 radially outward of a maximum deformation radially corresponds to the inside.
  • the surface roughness of the shell 5 of the roll 1 should be below a Ra value of 0.3 ⁇ m.
