Definitions

  • the invention relates to a roller or calender roller according to the preamble of claim 1, and to a method for producing a roller according to the preamble of claim 11.
  • calender rolls which have a covering as the uppermost layer, which consists of paper or textile material.
  • calender rolls whose covering consists of a plurality of discs of textile material or cotton fabric, which are threaded onto a metal core and are strongly pressed in the axial direction.
  • These rollers form a covering or a surface which has a certain elasticity and, moreover, is relatively cheap and, in the event of wear, can be turned off a bit in order to again achieve a uniformly smooth surface.
  • it has been tried to postpone a metal cylinder fitting exactly on the textile layer and in turn applied to a layer of plastic or rubber, for example.
  • the diameter of the metal tube has to be exactly the same as the diameter of the roll otherwise mechanical problems will occur.
  • the invention has for its object to provide an aforementioned roller and a method for producing a roller with which the problems of the prior art can be avoided and in particular inexpensive and technically manageable another layer structure can be applied to existing treatment facilities.
  • a roller has a hard base on which a covering of paper or textile material is applied, which has a certain thickness, in particular several centimeters.
  • the covering consists of a large number of individual thin layers of paper or textile material. These are compacted or compressed for a certain dimensional stability.
  • This covering made of paper or textile material is structured on its surface.
  • plastic is applied, in particular liquid plastic, which has the effect of an adhesive and additionally for a mechanical connection, in particular for load transmission, is used.
  • a stabilizing layer of fiber material is applied. This is also impregnated with plastic, which hardens and forms a stable fiber-reinforced layer together with the fiber material.
  • a kind of intermediate layer can be formed by plastic and fiber material, which in turn has sufficient strength.
  • structuring the surface of the covering below in turn, it is achieved that the plastic can penetrate into the paper or textile material in the depth and, so to speak, soak it at least one piece.
  • a particularly good adhesion is achieved in addition to the structuring itself and also a good mechanical connection, in particular for load transfer.
  • the surface can be opened so to speak by structuring, so that liquid plastic or adhesive can penetrate.
  • stabilization layer with fiber material on the one hand, a reasonably smooth surface of the roller can be achieved again so that the structuring is balanced again.
  • a known stable layer is achieved by the composite of fiber material and plastic or adhesive.
  • the roll is a calender roll, or such is used to produce a new roll with the described method.
  • a roll can form a rolling mill after completion as a calender roll with a metal counter roll, for example for smoothing paper surfaces.
  • a coating can then be applied to the stabilization layer described above, which advantageously consists of plastic or rubber. This may have a thickness of a few millimeters to a few centimeters and be adapted to the desired purpose of hardness and other properties.
  • the textile material is advantageous to cotton.
  • the textile material consists of a cotton fabric, as it is also used for jeans or the like. This allows a relatively cheap availability.
  • Other possibilities are shares of wool or synthetic fibers in the textile material, for example under the name Nomex.
  • a substructure of the roll is preferably metallic for sufficient strength. Particularly preferably, it is a solid or hollow metal core, which also forms the axis of rotation in the case of a roller.
  • Washers made of paper or textile material can be applied to a substructure or, in the case of a roller, threaded onto a roll core and thus form the coating. For this purpose, they are compacted and compressed, in the case of a roller advantageously by means of clamping means at the ends, which may be, for example, nuts to be screwed.
  • the structuring of the surface of the covering may, for example, have grooves which, depending on the thickness of the covering and other requirements, may have a variable depth. This depth can be between 3mm and 20mm, for example at just under 10mm. It is considered advantageous if a uniform and uniform structuring is provided, so for example only grooves. These can all be provided at the same distance from each other, wherein they are advantageously closely adjacent. By applying the grooves as directly as possible to each other, their number per surface unit becomes as large as possible and thus also their adhesion-improving effect. Likewise, this can be the mechanical connection with which the load transfer is improved. Thus, mechanical loads from the outer layer can be better transferred to the roll core.
  • a structuring of the surface is provided so that it runs only in the circumferential direction or has no or only a small longitudinal component mainly in the axial direction of the roller. This would otherwise cause a force and movement effect of the topmost pad with deflection in the longitudinal direction of the axis of the rotating rollers from a pressure along the nip line of a Kalanderwalzenwerks, which is to be avoided, of course.
  • Grooves thus extend substantially or advantageously exclusively in the circumferential direction as self-contained circular grooves. It is also possible to provide a groove in the manner of a screw thread. Thus, the aforementioned properties are also achieved, although not quite so good.
  • holes or recesses are also possible in addition to the aforementioned elongate grooves. These should be distributed equally. Furthermore, it is advantageous and manufacturing technology favorable to form them in about the same size. They can be applied by drills or mandrels on rotating rollers, as well as possibly by laser beams.
  • plastic or adhesive may be provided resin, for example, synthetic resin such as epoxy resin.
  • resin for example, synthetic resin such as epoxy resin.
  • a plastic may advantageously be a thermoset.
  • a fibrous material may preferably be selected from the following group: glass fiber, carbon fiber, aramid fiber or boron fiber.
  • the application of the fiber material to a roller as a treatment device can take place in that the roller is rotated and the fiber material is wound up.
  • the fiber material is as compact as possible, and is applied close together and evenly.
  • another layer of fiber material can be applied.
  • the fiber material of desired thickness can be applied in a single pass. It is considered advantageous if the fiber material is already applied impregnated with liquid plastic or adhesive.
  • another coating can either be applied directly or first the surface can be smoothed, for example, ground off.
  • the topmost coating is a polymer material, for example rubber or a plastic.
  • a calender roll 11 is shown. This consists of a plurality of discs 13 from the aforementioned paper or textile material. The discs 13 are threaded onto a core 15 which simultaneously has shaft ends. By two retaining washers 17 at the left and right ends of the paper discs 13 are pressed together.
  • the surface 19 or the disks 13 are treated with a cutting tool 21 in accordance with a customary turning operation.
  • grooves 23 are cut.
  • the grooves 23 are exactly parallel, directly adjacent to each other and with the same distance from each other exactly in the circumferential direction on the roller 11th
  • the individual disks 13 are not shredded at their outer edges, but cut relatively smoothly. This means that they are workable like a solid solid material. Nevertheless, due to the processing by the thus formed surface or total area of the adjoining outer edges of the discs 13 is created from the outside so to speak open or accessible to liquid structure. This will be explained in more detail below.
  • a structuring is shown, as holes or blind holes 26 can be introduced into the surface 19. This can be done for example by drilling as well as laser beams or the like. Furthermore, as shown, the holes may be made as pure cylindrical blind bores. Likewise, they can run narrower downwards.
  • Fig. 3 are shown in a split view, the various steps to starting from a provided with grooves 23 treatment device, for example, the calender roll 11 according to Fig. 1 to apply the further layer structure. It is based on a structure of the surface according to Fig. 1 in which the retaining washers 17 are already provided with the grooves 23.
  • resin 30 is applied by means of a nozzle 32.
  • another application device can also be provided.
  • the order is made as shown in the second step right next to it, that at least the grooves 23 are covered with the synthetic resin 30 reasonably well, advantageously not completely filled.
  • Fig. 3 In the third step in Fig. 3 are made of individual fibers 35 existing rovings 34 wound. These can be applied in a kind of endless form. It can be provided, as can be seen by the state according to the fourth step, that the fibers 35 are first filled approximately with the grooves 23 between the tips 24. Subsequently, according to the fifth step, fiber material 35, advantageously again in the form of rovings 34, is applied together with further synthetic resin, but this time distributed over the entire surface. While here in the first step by the fiber material 35, the grooves 23 have been compensated or filled compared to the intermediate points 24, now a total overlapping layer of fiber material 35 is applied. This serves to strengthen the Furthermore, a more stable and coherent substructure can be created for a subsequent layer structure.
  • the entire roller 11 is covered with a layer of fibrous material 35 impregnated with synthetic resin 30.
  • this application of the layer or the production of the layer should be such that either by winding or subsequent processing, the surface is already reasonably even and even.
  • a further coating 37 of polymer material can be applied to the finished cured layer of fiber-reinforced synthetic resin material, for example of rubber or plastic, depending on the intended use.
  • this again corresponds to the already known method.
  • this functional layer 37 made of polymer material due to the stable intermediate layer of fiber material 35, the roller behaves neutrally or, as it were, its properties are not influenced or embossed by the underlying structure of paper discs 13. Above all, loads can be transmitted better from the surface to the underlying roller 11 due to the improved mechanical connection.
