Definitions

  • the invention relates to a calender with a stack of rolls, comprising at least three, supported by a common stator rollers, which form between them nips for the treatment of a material web and the axes lie in a plane inclined to the horizontal stacking plane, the position of at least the top and bottom Roller is variably adjustable along the roll stack.
  • a calender is known for example from DE 199 04 180 C1.
  • the inclination of the roll stack has, inter alia, the advantage over a vertical arrangement of the roll stack that even with unfavorable loading of the press nips always a minimum load of the roll bearing is guaranteed.
  • a roller separation and the replacement of a roller by a roller of other diameters are feasible.
  • the object of the invention is to minimize the production cost with the greatest possible compactness. In addition, a good operation-accessibility, a short roll change time and easy maintenance are sought.
  • this object is achieved in that the pins of the uppermost and the lowermost roller each mounted in a pivotally mounted on the stand lever and at least the levers of each roll side, preferably both sides of the roll, i. all levers are the same.
  • the angle between the stack level and the horizontal should be between 15 and 35 °, in particular between 20 and 30 °.
  • the journal bearing of the lever is formed by two half-shells, whose parting line is inclined to the horizontal and preferably extends through the roller center.
  • the angle between the parting line and the horizontal should be between 15 and 35 °, and the dividing line between the half-shells should preferably be approximately parallel to the stacking plane.
  • the levers force transmitter To initiate pressing forces in the roll stack should act on the levers force transmitter, which are designed to simplify the construction of the same.
  • a simple, very stable and relatively lightweight stand construction results when the side walls of the stator running perpendicular to the roller axis are formed by two parallel plates. This in turn allows the levers between the two parallel plates of the stator pivotally to store, which allows a safe demarcation of the pivoting range in a very compact design.
  • the levers can also be used for fastening additional elements of the calender, in particular a scraper for the respective roller.
  • At least the top and bottom rollers should be designed to be deflection-controlled.
  • the construction is particularly simple if the roll stack comprises only three rolls. This is already sufficient in most applications.
  • Figure 1 a schematic side view of a calender
  • FIG. 2 a partial view of a fleece 5.
  • the calender according to FIG. 1 has a stand 1, which carries a stack of rolls comprising three rolls 2a, 2b, 2c, whose stacking plane 3 extending through the roll axes runs at an angle of 25 ° to the flat line 4.
  • the material web 10 can be guided for treatment only by one or both nips.
  • the calender shown here is particularly suitable for smoothing a material web 10 in the form of a paper or board web.
  • the stack consists of an upper end roll 2a and a lower end roll 2c and a middle roll 2b.
  • the upper 2a and lower end rolls 2c are formed at their ends, i. each supported on the roll neck by a Flebel 5, which is pivotable about a pivot axis of the stator 1.
  • All Flebel 5 are the same design and are each loaded by a force transmitter 8 in the form of a piston-cylinder unit. All these force transmitters 8 are the same. As a result, reduced by the same design of Flebel 5 and the force transmitter 8 the effort considerably.
  • the bearing housing of the center roller 2b is firmly supported on the stator 1.
  • the storage of the roll neck is formed at the levers 5 of two half-shells 6.
  • the, extending through the roller center dividing line 7 between the half-shells 6 to the horizontal 4 is inclined.
  • the angle between the dividing line 7 and the horizontal 4 is between 15 and 35 ° or even corresponds to the inclination of the stack level 3 to the horizontal. 4
  • Half shell 6 can be easily installed and removed.

Abstract

L'invention concerne une calandre comprenant un empilement de rouleaux, qui comprend au moins trois rouleaux (2) portés par un support (1) commun, lesquels forment entre eux des emprises pour le traitement d'une bande de matériau (10) et dont les axes se trouvent dans un plan d'empilement (3) incliné par rapport à l'horizontale (4), la position d'au moins le rouleau supérieur (2a) et le rouleau inférieur (2c) pouvant être réglée le long de l'empilement de rouleaux. Les coûts de fabrications peuvent être réduits en logeant les tenons du rouleau supérieur (2a) et du rouleau inférieur (2c) chacun dans un levier (5) fixé de façon pivotante sur ls support (1) et le logement de tenons des leviers (5) étant formé par deux demi-coquilles (6), dont la ligne de séparation (7) est inclinée par rapport à l'horizontale (4).
