Definitions

  • the invention relates to a calender for treating, such as smoothing or satinizing, a web, in particular a paper web, with at least two rolls forming a nip between rolls and a winding device.
  • Calenders of this type are widely known, for example from the brochure "The New Super Calender Concepts" from Sulzer Papertec from 1994 (code 05/94 d).
  • the calendered web is formed into a roll in the winder, the axial length of which corresponds to the width of the web. With long rolls it is very difficult to produce an even winding. There are therefore numerous proposals for providing the winding device with additional devices which are intended to improve the winding result.
  • the invention has for its object to improve a calender of the type described in terms of its performance.
  • At least one slitter is arranged between the last nip and the winding device for dividing the web into at least two partial webs and that the winding device has at least two winding stations for each partial web.
  • the web is loaded much less because there is no winding up at the exit of the calender and no unwinding at the entrance to the slitter.
  • the web material can therefore be subjected to greater stress.
  • the winding stations each have a drive device with a control device which keeps the peripheral speed of the partial web rolls approximately equal to the web speed in the calender, but additionally effects individual corrections of the peripheral speed. This further improves the winding result.
  • a control device which acts in particular in zones for the calender functions, such as compressive stress in the nip, dwell time in the nip, temperature or humidity, is provided and additionally provides the desired properties of the web, such as smoothness or gloss depends on parameters of the finished web, the partial webs or the partial web rolls.
  • a calender forms a system with a large number of possible influences on the web to be treated. The same property can be achieved with different combinations of the calender functions, for example, if you replace a lower compressive stress in the nip with a higher temperature. It is therefore not difficult to introduce an additional dependency, which ensures greater uniformity in the winding.
  • Measuring devices for the partial web roll diameter and / or the tensile stresses of the partial webs, which serve as parameters, are preferably provided. Taking these parameters into account results in a particularly good winding quality.
  • part of the calender functions can be controlled zone by zone and that the control device controls the zones differently depending on parameters of the partial webs or the partial web rolls. Taking into account the individually controlled zones, the optimal winding quality can be achieved for each individual partial winding.
  • the inventive proposal is particularly important because the web, before entering the first Nip occurs, was already subjected to a winding process at the end of the paper machine and a winding process at the entrance of the calender. It is therefore ensured that this strain on the web occurs only once.
  • An automatic web feed device is advantageous. Such a device is known under the name "Flying Splice”. This allows an automatic roll change at the calender entrance.
  • Each winding station is advantageously provided with an automatic winding tube changer. Whenever a sub-roll has reached its maximum diameter, a new winding tube is automatically fed so that the new sub-roll can be built up without interrupting the calendar operation.
  • the calender illustrated in FIG. 1 has a roll stack 1 which consists of eight rolls, namely a heatable, deflection-controllable hard top roll 2, a soft roll 3, a heatable hard roll 4, a soft roll 5, a soft roll 6, one heatable hard roller 7, a soft roller 8 and a heatable, deflection-controllable hard lower roller 9.
  • a heatable, deflection-controllable hard top roll 2 a soft roll 3
  • a heatable hard roll 4 a soft roll 5
  • a soft roll 6 one heatable hard roller 7, a soft roller 8 and a heatable, deflection-controllable hard lower roller 9.
  • there are six working gaps 10 to 15, each by one hard roller and a soft roller are limited, and an alternating gap 16, which is limited by two soft rollers 5 and 6.
  • a paper web 17 is fed from an unwinding device 18, passes through the working gaps 10 to 12, the changing gap 16 and the working gaps 13 to 15 under the guidance of guide rollers 19, whereupon it is wound up in a winding device 20.
  • the paper web rests on one side with the hard rollers in the three lower working gaps 13 to 15, so that the desired surface structure, for example gloss or smoothness, is achieved on both sides.
  • the unwinding device 18 connected to a flying splice system is, as is generally known, only shown as a box.
  • At least one of the rollers 2 to 9 has its own drive 21. In many cases, however, it is expedient to provide all the rollers with such a drive, for example if an automatic drawing in of the paper web is desirable.
  • the paper web 17 When the paper web 17 has left the last nip 15, it runs through a slitter 32, which has rotating cutting knives 33 and 34, which sit on a common axis 35 and are driven by a motor 36. As a result, the paper web 17, which can have a width of, for example, 8 or 10 m, is divided into individual partial webs 17a, 17b, 17c ...
  • a winding device 37 follows, which has a number of winding stations 37a, 37b, 37c ... which corresponds to the number of partial webs 17a, 17b, 17c ...
  • a central roller 38 which has a drive device 39.
  • each winding station has a support roller 40a, 40b, 40c ..., each of which is provided with its own drive device 41.
  • Each partial web 17a ... is assigned a measuring device 44 for measuring the tensile stress of the partial web.
  • Each partial web roll 43a ... is assigned a measuring device 45 for measuring the roll diameter.
  • the measured values are processed in a second control device 46, which adjusts the drives 39 and 41 in such a way that the peripheral speed of the central roll 38 is approximately equal to the web speed in the calender, while for each partial web roll 43a ... necessary corrections are made by the drive device 41 of the support rolls . If the peripheral speed of the support roller 40a is greater than that of the central roller 38, the result is a harder winding, if it is lower, a softer winding.
  • control device 46 is connected to the control device 31 via a signal path 47.
  • additional data which are of interest for the winding process for example the thickness of the web or its moisture, can be fed to the control device 46 via further inputs 48.
  • the control device 23 is able to calender function based on the information supplied to influence that the paper web 17 leaving the last nip 15 largely corresponds to the optimal winding conditions and therefore no or hardly any interventions are to be carried out in the area of the winding device 37. In many cases it is therefore possible to dispense with individual regulation of the support rollers 40a ... and to provide continuous support rollers. Particularly when the paper web 17 in the calender is influenced differently in zones, it can be achieved that the partial webs 17a ... are kept so uniform that the same winding drive can be used for all of them.
  • winding devices can also be used in which the winding tube is supported and driven. It is also possible to use the calender inline.
