Definitions

  • the invention relates to a method for calendering a web according to the preamble of claim 1 and a calender for this purpose.
  • Out DE 198 20 089 C2 is a method for calendering a web with a multi-roll calender known in which a plurality of intermediate rolls are arranged between an upper and lower bendable roll.
  • This roll package is concatenated and forms nips, which passes through the web. Due to the inherent weight of the rolls and their associated overhanging loads, such as guide rolls, roll necks and bearing housings, the compressive stress increases vertically and obliquely in the nips from top to bottom. This fixed to a roller set line load increase results in the natural line load characteristic.
  • it is provided to selectively bend the intermediate rolls and to adapt the bendable end rolls to this bend.
  • the targeted bending of the intermediate rolls by introducing deformation forces leads to a discharge or load of the rollers, so that the line load difference between the upper nip and the lower nip can be adjusted freely.
  • the bending deformation due to shear deformation as well as the possible raw reevaluation of the intermediate rolls is included in the calculation of the values for the deformation forces.
  • the bending lines of the intermediate rolls are adapted to one another.
  • the Rohrovalmaschine the intermediate rolls which occurs especially with larger roll diameters and the hollow rollers used as soft rolls, complicates the setting of a uniform load in the nip.
  • the most uniform possible pressure curve in the nip over the width of the material web, in particular a paper web is required in order to avoid differences in thickness and quality transversely to the running direction of the material web.
  • a calender for the treatment of a paper web which has at least one end loadable stack of rolls comprising a respective upper and lower end roll and a plurality of intermediate rolls.
  • the arrangement of the rolls takes place in a roll stack level and the rolls comprise hard and soft rolls to form soft nips.
  • each soft roll forming an intermediate roll has a larger diameter than a soft end roll.
  • the larger diameter of the soft intermediate rolls increases the service life of the double-rolled intermediate rolls which define an upper and lower nip.
  • a disadvantage is the greater Rohrovalmaschine of intermediate rolls with a larger diameter, which requires additional measures to ensure a uniform load in the nip.
  • the object of the invention is therefore to provide a method for calendering a web and a calender for this purpose, which make the load in the nip uniform.
  • a method for calendering a web, in particular a paper or board web, and a calender which balance the Rohrovalleiter the at least one intermediate roll by a targeted bias of the roll shell in the directions where the at least one intermediate roll limits a nip.
  • the bias voltage is chosen such that bias voltages are set differently in the region of a central zone than in the area of the two-sided edge zones of the respective limited nips.
  • the biasing causes the roll shell of the intermediate roll (s) receives internal moments of force which are effective in the direction of each limited nip, ie directed radially outward, and to correct a nip error caused by a Rohrovalmaschine under load.
  • the Rohrovalmaschine is compensated for this during operation of the calender by a correction force profile.
  • the biases can be applied so that a circumferential profile correction is adjustable with respect to the width of the peripheral portion. Narrow ranges are preferred which only slightly exceed the respective nip length.
  • the biases can be chosen substantially equal in an intermediate roll with oppositely-limited nips.
  • the adjustment of the bias voltages can then take place via a common pressure medium source with common supply lines, whereby a cost-effective design of the intermediate roll (s) is possible.
  • different biases in the direction of the limited nips of an intermediate roll allow the adjustment of a selectable bending of the intermediate roll for a variable characteristic.
  • the bias in the middle zones relative to the edge zones can be used to compensate edge profile errors of the adjacent rollers.
  • the edge zones of the prestressed intermediate roller can be additionally loaded or relieved.
  • variable web widths can be set.
  • the biases can be controlled such that the nip edges are pulled away by a different loading of the center zones and the edge zones with a selectable pretension.
  • a variable nip width can be set hereby.
  • FIGS. 1 and 2a show a calender for the treatment of a web, in particular a paper or board web.
  • the calender 1 comprises at least one roll stack 2 which can be loaded from one end or both ends and has an upper end roll 3 and a lower end roll 4 and at least one intermediate roll 5.
  • the end rolls 3, 4 are preferably designed as bending set rolls. Depending on the quality of the calendering to be achieved, the number of intermediate rolls can be selected.
  • three intermediate rollers 5, 6, 7 are provided, which are arranged together with the end rollers 3, 4 in a roller stack level, which extends vertically. Alternatively, the roller stack level may be inclined. Between each two of the rollers 3 to 7 nips 8, 9, 10, 11 are formed, which pass through the paper or board web 12 in a direction of passage D.
  • the rolls 3 to 7 are preferably formed as hard and soft rolls.
  • the upper end roll 3, the lower end roll 4 and the middle intermediate roll 5 are preferably soft rolls, ie rolls, which are provided with an elastic cover in a roll stack 2 with a total of five rolls.
  • the nips 8, 9, 10, 11 are then all soft nips.
  • the roll stack 2 is used for one-sided treatment of a web. For two-sided treatment, a second suitably designed roll stack can be provided.
  • At least one intermediate roll in this case the intermediate roll 5, which is preferably designed as a soft roll, is a roll which can be prestressed in the directions of the nips 9, 10 delimited by this intermediate roll on a circumferential section by application of forces in the direction of the respectively defined nip.
