Definitions

  • the invention relates to a calender arrangement with a Shoe roll, which has a circumferential jacket, the with the help of a pressure shoe towards a counter roller is resilient.
  • the invention further relates to a method for satinizing a material web in one Breitnip, which is between a circumferential coat and a counter roll is formed, taking the jacket with the help of a pressure shoe attached to the inside of the coat bears against the counter roller.
  • Such a calender arrangement and such Methods are for example from DE 299 02 436 U1 or DE 299 02 451 U1 known.
  • the shoe roll forms together with the counter roll a nip through which a material web, in particular a paper or cardboard web, can be performed.
  • the mantle of the runner is relatively compliant, so that it is about one predetermined peripheral portion to the shape of the counter roll adapts. So that the length of the nip in the direction of movement increased.
  • Such a nip will also Called "Breitnip".
  • the enlargement of the nip has that Advantage that one with the same web speed Treatment time can be longer in the wide nip than in a conventional nip that is between two Rolling is formed. This is done with the same force the compressive stress in the wide nip is lower, so that the compression of the material web is correspondingly smaller is held.
  • the jacket has the required flexibility, it is usually made of a plastic. In some cases it is not desirable for the Jacket gets direct contact with the counter roller.
  • plastics are only thermally limited resilient. If you heat the counter roller, then you have to them to the required amount of heat in the wide nip to be able to feed in, have surface temperatures, which can be higher than 200 ° C. This is not a problem as long as a web of material passes through the nip is led. The web of material then separates them Counter roll from the jacket.
  • the invention has for its object a system to prevent the jacket on the counter roller.
  • This task is the beginning of a calender arrangement mentioned type in that the pressure shoe has a support surface, the width of which in one direction is changeable parallel to the axis of the counter roller.
  • the width of the pressure shoe is then adjusted so that the jacket only in the area of the material web against the Counter roll is pressed. However, this is the area the material web between the jacket and the counter roll, so that there is direct contact between the coat and the counter roller can be avoided. In the Areas outside the material web lack support of the jacket through the pressure shoe. Without these But the coat doesn't get as much support anymore approximated to the counter roller that the danger of a thermal overload exists. The coat will held at its axial ends anyway, so that the jacket is conical starting from the ends of the pressure shoe runs away from the counter roll.
  • the concept of "Counter roller” is to be understood generally here. In the in most cases, the backing roller is actually through formed a cylindrical body.
  • the "counter roller” can also be used as an abutment in other ways be designed for the jacket, for example as Ribbon or coat.
  • the counter roller is preferably heated. If introduces heat into the wide nip via the counter roller, then you can heat the material web, which is also positive on the treatment of the material web, in particular the surface properties of a paper or Cardboard web, affects.
  • the width of the support surface is preferably dependent changeable from the width of a material web, the one wide nip between the jacket and the counter roller passes. This provides a criterion based on which you can adjust the width of the support surface can.
  • the change in the width of the support surface is a relatively simple measure, so that one without major renovation work in different ways can satinize wide material webs.
  • the support surface preferably has one in the direction Limitation movable parallel to the axis of the counter roller on.
  • the support surface can with the limitation in mind stop being outside of the limit mechanical Support completely lacking. But you can also imagine the support surface through a pressurized standing pad of a hydraulic fluid formed becomes. In this case, the limit is limited this pressure pad. If the limit moved then the axial length of this pressure pad just bigger or smaller.
  • the limitation is preferably a cross bar formed between two sealing strips which extend parallel to the axis of the counter roll.
  • the two sealing strips are in the direction of movement the material web immovable in relation to the Jacket arranged. You define in the direction of movement the web of material the beginning and end of a zone, in which is pressurized. The setting in the width direction then occurs through the movement of the Sealing strip.
  • the cross bar can preferably be moved in a room, which is closed at the front.
  • the frontal closure then forms a limit for the Movement of the cross bar.
  • the front end connects doing the two sealing strips, which is a special one great mechanical stability allowed.
  • the space preferably has a pressure medium feed on. Accordingly, the room can be pressurized become. This pressure then builds up a counter pressure the pressure that exists in the support surface. Even if the pressure in the room is not as big, you can balance the forces on the cross bar at least partially. It is then easier to attach the cross bar to the desired position.
  • the cross bar be provided in the manner of a U with two legs that are sealingly guided on the sealing strips.
  • the cross bar then forms one with the two legs Drawer between the sealing strips or outside the sealing strips can be moved to the axial Change the length of the support surface.
  • the sealing strips preferably have a pressure arrangement on.
  • the sealing strips are so with a certain Force pressed against the coat from the inside, so that at least in the axial direction a seal between the Sealing strips and the surrounding jacket can be achieved can, which allows the required in the support surface Building pressure.
  • the pressure arrangement can be coupled to the cross bar so that the sealing strips pressed against the jacket only in one area be limited by the cross bar. Outside the jacket can then move away from the counter roll, because he is no longer from the sealing strips is sufficiently supported.
  • the pressure shoe is on at least one axial end with an extension element renewable. So it is only possible to extend the pressure shoe in discrete steps or shorten it. Attaching an extension element on the pressure shoe is a relatively simple one Measure so that you no longer have the disadvantage of one Accept continuous extension or shortening can.
  • extension element from a non-active position in which there is a distance has to the jacket, shifted to an active position in which it lies against the inside of the coat. You get there an extension or a shortening of the Pressure shoe simply by having an extension element emotional. The movement or relocation of one Extension element is relatively easy too realize. There are no major renovations required. In particular, it can be provided that Relocation of the extension element a drive available is so that you can control the relocation from the outside can.
  • the inactive position is preferably inside of the jacket arranged.
  • the active position is anyway arranged inside the jacket.
  • the relocation movement then finds completely inside the mantle instead, so that you can carry through the coat or does not have to realize its end faces.
  • the extension element is between the inactive and the active position on a ramp movable. So you arrange one inside the coat Carrier ramped at predetermined sections is trained. If you have an extension element moves along this ramp, then it approaches further on the coat or it moves away from him. With the help of the ramp, the individual positions can be the extension elements set relatively easily. Because of the slope of the ramp, it is too possible with relatively low forces that lead to movement of the extension element exercised along the ramp can be correspondingly large forces towards to generate on the backing roll when the extension element is in its active position. These powers are only required as holding forces during operation.
  • the ramp preferably runs in the axial direction. In There is usually sufficient space in the axial direction to disposal. You can then drive in the axial direction let act on the extension elements.
  • an axially arranged further outside Extension element a longer foot than an extension element arranged axially further inside having. So you can all extension elements Arrange on the ramp. An axially outward lying extension element is then over the corresponding longer foot in the same radial position moves like an axially inner extension element.
  • the ramp is inclined relative to a direction that on a press level through the wide nip between the Jacket and the counter roller is vertical.
  • the press level is basically spanned by the axis of the Counter roller and the central axis of the jacket of the shoe roller.
  • the extension elements moved and moved parallel to a radial direction this way up or down the ramp. This Design is advantageous if in the axial direction not enough space is available.
  • Each extension element preferably has one Lubrication on.
  • the lubrication can be hydrodynamic his.
  • the extension elements and the pressure shoe so designed that the lubricating oil adhering to the jacket during movement of the jacket relative to the pressure shoe a lubricating film between the pressure shoe or the extension element or elements and can form the coat.
  • the extension elements then basically have the same cross-sectional shape like the pressure shoe. If you have a hydrostatic Provides lubrication, then both the pressure shoe as well as the individual extension elements each with a pressure connection for the lubricant be provided. Each extension element can then one have their own pressure bag over which the lubricant can be fed.
  • the pressure shoe and each extension element a rounding on its axial outside on. This will damage the jacket of avoid inside at the point where the support ceases through the pressure shoe. You avoid one sharp edge, so that the life of the jacket is extended becomes.
  • each extension element on its axial inside there is a matching rounding Forming has. You get, so to speak a "seamless" surface of the pressure shoe.
  • the task is in a method of the aforementioned Art solved in that depending on the width of the material web, the axial limitation of a Support surface of the pressure shoe changed.
  • the width of a pressure pocket changed, which forms the support surface.
  • This hydraulic fluid has a larger one or a smaller axial length act on the jacket the axial treatment length also changes.
  • the change in the width of the pressure bag, more precisely said its axial length is relatively easy to carry out.
  • a calender arrangement 1 according to FIGS. 1 and 2 has a shoe roller 2 with a counter roller 3 Breitnip 4 forms, through which a material web 5, in present example is a paper or cardboard web can be to get there with increased pressure and increased Temperature to be applied.
