Definitions

  • the invention relates to a calender with a roll stack, of the two end rolls and at least one intermediate roll has, the end rollers each one deflection compensation devices acting in the direction of the intermediate roller have (see - EP-0 661 405 A).
  • Such calenders are often designed as super calenders. They have a variety of rollers, in usually 10 or 12, arranged vertically one above the other are. The end rollers are in the top one and the lowest position. You will be accordingly also as top roller or as bottom roller designated.
  • Calenders of this type are used, for example, for calendering a paper web, i.e. the paper web is covered by the Column passed between adjacent rollers. By suitable means are placed on the rollers under pressure. The paper web is treated by this on the one hand, compresses and receives an improved one Surface quality, for example a higher one Shine or better smoothness.
  • pressing means for example Hydraulic cylinder, towards the former End roller pressed. Or the top roller and the bottom roller have opposing pressure medium. Which resulting deflections can by the deflection compensation be compensated so that all nips assume a straight course.
  • the paper producer now often also wants a matte satin can perform.
  • a suitable one for this Soft calenders are often used for cost or space reasons not available, so the super calender this Function must also perform.
  • one of the vertically movable supports stored rollers, usually one of the intermediate rollers, in the roll stack by a suitable mechanical Locking means fixed in position. All vertically movable rollers below it including the one designed as a deflection compensation roller Bottom roller are through the hydraulic cylinder pressed up against the locked roller. The Deflection of the rolls is in turn by the deflection compensation device the lower roller compensated.
  • the invention has for its object a satin operation with the help of such a calender to be able to perform without the roller-specific Contact pressures to be set.
  • This task is accomplished by a calender of the beginning mentioned type in that at least one end roller an additional one, in the direction of the intermediate roller has deflection compensation device acting away and that an additional, as a deflection compensation roller trained additional roller on the intermediate roller facing away from this end roller is.
  • This combines a conventional calender with an additional calender for matt satin operation suitable is.
  • a roller is used for this used, namely as the final roller of one Deflection compensating roller used for calenders. It is practically no additional space is required, if you go from a slight increase in height of the new calender. Also those that have to be applied Costs are limited because none additional seating is necessary.
  • the additional Effort does include the end roller in question with a second deflection compensation device provides and an additional deflection compensation roller built in. In other words, this can be said also describe that one as the deflection roll trained end roller by one position moves and a double-acting deflection roller built in. But since with the new calender the matte satin operation practically without commitment can perform on pressures by the or Rolls are determined, you can accept this effort.
  • the contact pressures can now be in wide ranges be adjusted.
  • One can use both with relatively low Push because the deflection compensation devices the final roller and the additional roller in any case can cooperate and ensure that the nip stays straight. If you drive with a pressure would like to compensate for the inherent deflection necessary pressures, then worked the counteracting deflection compensation devices end roller and additional roller together. If you want to work with a lower pressure, then use the deflection compensation device from the end roller, towards the intermediate roller or the intermediate roller works. This leads to a Relief of pressure from the nip to the additional roller there.
  • the additional roller and the associated end roller a common Have storage facilities on the machine frame.
  • the machine frame can, for example, the chair of the calender or the calender stand.
  • At least one of the rollers is on the Storage device can be moved relative to the other roller. This allows the nip between the open both rollers so that the additional roller actually is only operated when the satin satin operation is carried out.
  • the additional roller has a carrier which via a hydraulic cylinder is supported on the storage facility.
  • At least one of the rollers of the pair of rollers preferably has a separate roller and end roller Rotary drive on.
  • the satin operation can then without External drives are carried out.
  • the rotary drive on the storage facility arranged and with the stationary connected roller arranged on the bearing device is. You can then create a rigid connection between the Provide rotary drive and the roller because the positions of roller and rotary drive relative to each other do not change.
  • the bearing device is advantageously on the machine frame arranged movably. This is particularly so then advantageous if the additional roller in the area of Bottom roller is provided. You can if you do that Performs matt satin operation, the finishing roller of the separate the remaining intermediate rollers so that their wear remains low.
  • one roller a soft and the other roller has a hard surface. You can then use the additional roller to create a soft calender realize who is interested in the satin satin and has proven itself.
  • a calender 1 has a frame 2 in which a roll stack 3 is arranged.
  • the roll stack has one Top roller 4, a bottom roller 5 and several intermediate rollers 6 7 on. There are several guide rollers to guide the web intended.
  • the top roller 4 and the bottom roller 5 are collectively referred to as end rolls.
  • the top roller 4 and the bottom roller 5 are as deflection compensation rollers educated. They each point Deflection compensation devices 8, 9, which in Act on the intermediate rollers 6.
  • the intermediate rolls 6 and the lower roll 5 are relative movable to the frame 2.
  • the top roller 4 is on the frame detected.
  • the intermediate rolls are about this Bearing not shown attached to the frame 2.
  • the lower roller 5 is arranged in a bearing device 10, using a hydraulic cylinder 11 can be driven upwards. As soon as all nips between the intermediate rolls 6 and the lower roll 5 or the top roller 4 are closed, the Hydraulic cylinder 11 can also be used To increase pressure in the nips. A bend the rollers 4, 5, 6 is through the deflection compensation devices 8, 9 compensated.
  • the lower roller 5 additionally has a second deflection compensation device 14 on that towards the Additional roller 12 acts.
  • All deflection compensation devices 8, 9, 13, 14 can for example with hydrostatic sliding shoes be formed on a not shown Support is supported, the rollers 4, 5, 12 axially penetrated.
  • the additional roller 12 is on the bearing device 10 in slidable in the vertical direction. So it can be relative to be moved to the lower roller 5. In the in Fig. 1st position shown it leaves a nip 15th open towards the lower roller 5. The bearing device 10 is but moved so far towards the top roller 4 that all other nips are closed. The paper web 16 to be treated can then in normal operation be calendered.
  • Fig. 2 now shows another mode of operation in which all nips, in particular a nip 17 between the lower roller 5 and the next intermediate roller 6, are open. That is the nip 15 closed, i.e. the additional roller 12 is below Intermediate position of the paper web 16 on the lower roller 5.
  • the hydraulic cylinder 11 can be retracted here.
  • a separate Hydraulic cylinder provided for moving the Additional roller 12 is used on the storage device.
  • the deflection compensation device 13 and the deflection compensation device 9 put into operation.
  • the Deflection compensation device 9 prevents the lower roller 5 bends downwards when the Additional roller 12 no longer the necessary back pressure is applied.
  • Fig. 3 shows the possibility of the additional roller 12 as well to cooperate with the top roller 4.
  • the top roller has 2 deflection compensation devices 8, 14, the latter also from the intermediate rolls 6 works away, but this time upwards.
  • the deflection compensation device acts in the same way 13 of the additional roller 12 downwards, i.e. in the direction towards the intermediate rollers 6.
  • the bearing device 10 has a slide 18, which is arranged on the frame 2 vertically displaceable.
  • the hydraulic cylinder is used to drive the carriage 18 11, which is pressurized in FIG. 4 and in FIG. 5 is relieved.
  • a roller carrier 19 is on the carriage 18 arranged stationary.
  • the roller carrier 19 carries the lower roller 5. It also has a roller rotating drive 20 on, which is rigidly connected to the lower roller 5 is.
  • the hydraulic cylinder 21 can be smaller than the hydraulic cylinder 11, since it only has the additional roller 12 must shift with respect to the lower roller 5.
  • the hydraulic cylinder 11 but must be able to the lower roller 5 and raise all intermediate rollers 6.
