Definitions

  • the invention relates to a calender with a roll stack, which has two end rolls and at least one intermediate roll, the end rolls each having a deflection compensation device acting in the direction of the intermediate roll (cf. EP-0 661 405 A).
  • Such calenders are often designed as supercalenders. They have a plurality of rollers, usually 10 or 12, which are arranged vertically one above the other. The end rollers are arranged in the uppermost and the lowest position. Accordingly, they are also referred to as upper roller or as lower roller.
  • Such calenders serve, for example, for calendering a paper web, i. the paper web is passed through the gaps between adjacent rollers. By suitable means, the rollers are placed under pressure. The paper web is compacted by this treatment on the one hand and on the other hand receives an improved surface quality, such as a higher gloss or better smoothness.
  • pressing means such as hydraulic cylinders, in the direction of the former end roller. Or the upper roll and the lower roll have opposing pressure medium. The resulting deflections can be compensated by the deflection compensation devices, so that all nips take a straight course.
  • the paper producer now often wants to be able to perform a mat-sating.
  • a well-suited for this soft calender is often not available for cost or space reasons, so that the supercalender must also perform this function.
  • one of the rolls mounted in vertically displaceable supports is fastened in its position in the roll stack by a suitable mechanical locking means.
  • All under her vertically moving rollers including trained as deflection roll roller bottom roller are pressed by the hydraulic cylinder against the locked roller upwards.
  • the deflection of the rollers is in turn compensated by the deflection compensation device of the lower roller.
  • the invention has for its object to be able to perform a matte inking operation using such a calender, without being set to the roll-specific contact pressures.
  • This combines a conventional calender with an additional calender, which is suitable for the Mattsatinage ses.
  • a roller is used in common, namely the previously used as the end roll of a calender deflection roll. So there is virtually no additional space required, apart from a slight increase in the height of the new calender. Also, the additional costs to be kept within limits, because no additional stiffening is necessary.
  • the additional expense includes providing the respective end roller with a second deflection compensation device and installing an additional deflection compensation roller. In other words, this fact can also be described by shifting the end roller formed as a deflection adjusting roller by one position and installing a double-sided deflection adjusting roller. But since you can perform with the new calender the mattress sizing operation virtually no definition of pressures that are determined by the one or more rollers, you can take this effort.
  • the contact pressures can now be adjusted within wide ranges. You can drive both at relatively low pressures, because the deflection compensation devices of the end roller and the additional roller can cooperate in any case and ensure that the nip remains straight. If you want to go with a pressure that goes beyond the pressures necessary to compensate for the inherent deflection, then the counteracting deflection compensation devices of the end roll and additional roll worked together. If you want to work with a lower pressure, then you used from the end roll, the deflection compensation device, which acts in the direction of the intermediate roll or the intermediate rolls. This leads to a pressure relief of the nip to the additional roller.
  • the additional roller and the associated end roller have a common bearing device on the machine frame.
  • the machine frame can be, for example, the stiffening of the calender or the calender stand.
  • At least one of the rollers on the bearing device relative to the other roller is displaceable.
  • the nip between the two rollers can be opened, so that the additional roller is actually operated only when the matte transfer operation is performed.
  • the additional roller has a carrier which is supported via a hydraulic cylinder to the bearing device.
  • This training has two advantages. On the one hand, the end roller is fixedly arranged on the bearing device, so that in the roller control compared to a conventional calender practically no changes must be made. On the other hand, the additional roller is displaceable overall, so not only her coat. This simplifies the structure.
  • At least one of the rollers of the roller pair of additional roller and end roller has its own rotary drive. Mattsatinage ses can then be performed without third-party drives.
  • the rotary drive is arranged on the bearing device and connected to the stationary on the bearing means arranged roller. It is then possible to provide a rigid connection between the rotary drive and the roller, because the positions of roller and rotary drive do not change relative to one another.
  • the storage device is movably arranged on the machine frame. This is particularly advantageous when the additional roller is provided in the region of the lower roller. One can then, if one carries out the matte sating operation, separate the end roller from the other intermediate rollers, so that their wear remains low.
  • one roll has a soft surface and the other roll has a hard surface from the roll pair formed from the additional roll and the end roll. You can then realize a soft calender with the help of the additional roller, which has proven itself for the mat satin in and of itself.
  • a calender 1 has a frame 2, in which a roll stack 3 is arranged.
  • the roll stack has a top roll 4, a bottom roll 5 and a plurality of intermediate rolls 6 7.
  • For web guide several guide rollers are provided.
  • the upper roller 4 and the lower roller 5 are collectively referred to as end rollers.
  • the top roller 4 and the bottom roller 5 are formed as deflection compensating rollers. They each have deflection compensation devices 8, 9, which act in the direction of the intermediate rollers 6.
  • the intermediate rollers 6 and the lower roller 5 are movable relative to the frame 2.
  • the top roller 4 is detected on the frame.
  • the intermediate rolls are fastened to the frame 2 via bearings which are not shown in detail.
  • the lower roller 5 is arranged in a bearing device 10, which can be driven by means of a hydraulic cylinder 11 upwards. Once all the nips between the intermediate rolls 6 and the lower roll 5 and upper roll 4 are closed, the hydraulic cylinder 11 can also be used to increase the pressure in the nips.
  • a deflection of the rollers 4, 5, 6 is compensated by the deflection compensation devices 8, 9.
  • an additional roller 12 is also arranged, which is also designed as a deflection compensating roller and accordingly has a deflection compensating device 13.
  • This deflection compensating device 13 acts in the direction of the lower roller 5.
  • the lower roller 5 additionally has a second deflection compensating device 14, which acts in the direction of the additional roller 12.
  • All deflection compensating devices 8, 9, 13, 14 can be formed, for example, by hydrostatically acting sliding shoes, which are supported on a carrier, not shown, which passes through the rollers 4, 5, 12 axially.
  • the additional roller 12 is displaceable on the bearing device 10 in the vertical direction. It can therefore be moved relative to the lower roller 5. In the position shown in Fig. 1, it leaves a nip 15 to the lower roller 5 open. However, the bearing device 10 has been moved so far in the direction of the top roller 4 that all other nips are closed. The paper web 16 to be treated can then be calendered in normal operation.
  • the paper web 16 is guided only through the nip 15. It is satin finished there.
  • either the lower roller 5 or the additional roller 12 is provided with a soft surface.
  • the corresponding other roller then has a hard surface.
  • the deflection compensation device 13 and the deflection compensation device 9 are put into operation.
  • the deflection compensation device 9 prevents the lower roller 5 from bending downwards when the additional roller 12 no longer applies the necessary back pressure.
  • Fig. 3 shows the possibility of having the additional roller 12 also cooperate with the upper roller 4.
  • the upper roller 2 has deflection compensation devices 8, 14, the latter, although it also acts away from the intermediate rollers 6, but this time upwards.
  • the deflection compensation device 13 of the auxiliary roller 12 acts downward, i. in the direction of the intermediate rollers 6 back.
  • the bearing device 10 has a carriage 18, which is arranged vertically displaceable on the frame 2. To drive the carriage 18 is the hydraulic cylinder 11, which is set in Fig. 4 under pressure and relieved in Fig. 5.
  • roller carrier 19 On the carriage 18, a roller support 19 is first arranged stationary.
  • the roller carrier 19 carries the lower roller 5. It additionally has a roller turning drive 20, which is rigidly connected to the lower roller 5.
  • a further hydraulic cylinder 21 is additionally provided, which is relieved in Fig. 4 and set in Fig. 5 under pressure.
  • a carrier 22 is arranged, which passes through the additional roller 12 axially.
  • the elements of the deflection compensation device 13 are supported. With the help of the hydraulic cylinder 21, the nip 15 between the lower roller 5 and the additional roller 12 can be opened or closed.
  • the hydraulic cylinder 21 may be smaller than the hydraulic cylinder 11, since it only has to displace the auxiliary roller 12 with respect to the lower roller 5. However, the hydraulic cylinder 11 must be able to lift the lower roller 5 and all intermediate rollers 6.
