Definitions

  • the invention relates to a calender for treatment a web according to the preamble of claims 1 and 2.
  • a calender of the generic type is already Kind known (DE-OS 21 19 963), in which between the last nip and the winder there is at least one slitter.
  • the between the unwinder and the winder arranged working units are with drives equipped, which together with the settlement and Rewinding will be regulated and a synchronous run guarantee.
  • the train is loaded much less because of a Winding process at the exit of the calender and an unwinding process at the entrance to the slitter rewinder.
  • the web material can therefore be subjected to greater stress become.
  • the invention is based, with one Calenders of the type described in the introduction the winding quality to improve the partial web roles.
  • a calender forms a system with a large number of possible influences on the web to be treated.
  • Measuring devices for the partial web roll diameters are preferred and / or the tensile stresses of the Partial webs that serve as parameters are provided. At Taking these parameters into account results in a special good winding quality.
  • the invention proposal is special important because the web before going in the first Nip occurs, already a winding process on End of the paper machine and an unwinding process on Was subjected to the entrance of the calender. It will therefore ensured that this strain on the web only once occurs.
  • An automatic web feed device is advantageous. Such a device is under the name “Flying Splice” known. This allows one automatic roll change at the calender entrance.
  • Each winding station is advantageous with an automatic Provide winding tube changer. Whenever a partial roll reaches its maximum diameter a new winding tube is automatically fed in, so that the new sub-roll without interrupting the calender operation can be built.
  • the calender illustrated in Fig. 1 has one Roll stack 1, which consists of eight rolls, namely a heatable, deflection-controllable hard Top roller 2, a soft roller 3, a heatable hard roller 4, a soft roller 5, a soft Roller 6, a heatable hard roller 7, a soft one Roller 8 and a heated, deflection controllable hard bottom roller 9. Result in this way six working columns 10 to 15, each by one hard roller and a soft roller are limited, and an interchangeable nip 16 formed by two soft rollers 5 and 6 is limited.
  • a paper web 17 is taken from an unwinder 18 fed, passes under the leadership of idlers 19 the working column 10 to 12, the alternating gap 16 and the working columns 13 to 15, whereupon they are in a Winding device 20 is wound.
  • the three Upper paper columns 10 to 12 is the paper web with one side, in the three lower working columns 13 to 15 with the other side on the hard rollers so that the desired surface structure on both sides, for example gloss or smoothness is achieved.
  • the unwinding device connected to a flying splice system 18 is, as is well known, only as Box shown.
  • At least one of the rollers 2 to 9 has its own Drive 21. In many cases, however, it is advisable to provide all rollers with such a drive, for example if there is an automatic feeding of the paper web is desirable.
  • the rotating cutting knife 33 and 34 has which sit on a common axis 35 and through one Motor 36 are driven. This will make the paper web 17, which is a width of, for example, 8 or 10 m can have, in individual partial webs 17a, 17b, 17c ... divided.
  • winder 37 which is a number of winding stations 37a, 37b, 37c ... which corresponds to the number of partial webs 17a, 17b, 17c ...
  • a central roller is common to all winding stations 38, which has a drive device 39.
  • each winding station has a support roller 40a, 40b, 40c ... each with its own drive device 41 are provided. If a winding tube 42 of up in the gap between the central roller 38 and support roller 40a lowered and through the rotating surface of the two rollers is rotated, it takes a partial web and forms a partial web roll 43a. The same applies to the partial web rollers 43b, 43c, ...
  • Each partial web 17a ... is a measuring device 44 for Measurement of the tensile stress assigned to the partial web.
  • everyone Part web roll 43a ... is a measuring device 45 for Measurement of the roll diameter assigned.
  • the measured values are processed in a second control device 46, which adjusts the drives 39 and 41 such that the peripheral speed of the central roller 38 approximately is equal to the web speed in the calender, while corrections required for each partial web roll 43a by the drive device 41 of the support rollers he follows. Is the peripheral speed of the support roller 40a larger than that of the central roller 38 a harder wrap, it is less, a softer one Wrap.
  • control device 46 with the control device 31 via a signal path 47 connected.
  • control device 46 48 additional data for the Winding process of interest are fed for example the thickness of the web or its moisture.
  • the control device 23 is able due to the supplied information the calender function in such a way to influence that the last nip 15th leaving paper web 17 largely the optimal Corresponds to winding conditions and therefore little or no To make interventions in the area of the winding device 37 are. In many cases, therefore, one can do not use individual regulation of the support rollers 40a ... and provide continuous support rollers. In particular with different zones of influence the paper web 17 in the calender can be reached that the partial webs 17a ... kept so even are that the same winding drive is used for all can be.
  • winding devices can also be used where the Winding sleeve is mounted and driven. It is also possible to use the calender in inline mode.
