Definitions

  • the invention relates to a method for producing a profiled film, wherein the Film is provided with a corrugation, which runs obliquely to the edges of the film and has a substantially constant inclination angle, and wherein at least an edge region of the corrugated foil is formed. Further refers the invention relates to a method for producing an ordered packing, wherein at least one edge region of a foil provided with a corrugation is formed and a plurality of thus formed foils are arranged in parallel with each other. In addition, the invention relates to a corresponding device for producing a profiled foil with a first forming unit to the film with a corrugation to provided, and with a second forming unit for forming at least one Edge area of the film.
  • EP 1 044 787 B1 describes a process for producing such a package described with vertical course of the channels on the pack edge.
  • a planner Film strip is conveyed to a forming unit and pleated, with edges arise, which has a constant angle of inclination to the edges of the film strip have.
  • a further shaping unit are in peripheral zones of the Film strip by means of a pair of rollers, the edges by plastic deformation eliminated and simultaneously replaced by curved edges, the angle of inclination of the Center zone continuously increase to the edges of the film strip.
  • the packing sheet at one time across its entire width In a forming step, only a few channels can be transformed Packing be embossed. Otherwise, excessive deformations of the Packing sheet occur. There are therefore a large number of forming steps necessary to provide the entire plate with the channel structure.
  • Object of the present invention is therefore to show a method which it allowed, corrugated packing sheets with a modified edge region and such Packing sheets having packings produce almost as fast as usual packing sheets or usual packages without modifications. Furthermore, a device suitable for this purpose should be made available.
  • At least one Edge region of a corrugated foil by means of a stamp-shaped Forming tool formed, which alternately with the edge area in Contact and removed from the edge region, and a variety of such Formed films are arranged parallel to each other.
  • edge region of the film according to the invention may be favorable to first of all the edge region of the film according to the invention reshape and then adjust the film according to the size of the desired To divide packing element into individual sections. It has also been called proved advantageous, only the desired portions of the corrugated foil cut to length and then reshape the edge region according to the invention. For example, the deformation of the edge region immediately before stacking the cuts are made.
  • the separation of the section is preferably carried out simultaneously with the deformation of the Border area of another piece of film. While the stamp-shaped Forming tool acts on a specific edge region of the film is at the same time another part of the film cut off. Because of that Forming of the border area simultaneously with the necessary cutting anyway a portion of the film happens, that is for the production of the invention time not needed or only slightly larger than that for the production of a film time required without reshaped edge area.
  • An inventively suitable device for producing a profiled film has a first forming unit to provide the film with a corrugation, as well a second forming unit for forming at least one edge region of the film.
  • the second forming unit is a stamp-shaped forming tool formed, which alternately brought into contact with the edge region and of the edge area is removed.
  • border area becomes a strip-shaped, parallel to an edge of the film extending part of the film understood.
  • the size of the border area can vary, however, this preferably takes at most 10%, preferably at most 5% of the film one.
  • the area of the film between the two border areas or, if only one Edge area to be reshaped, the area between this edge area and the opposite edge of the film is referred to as the main area.
  • top and bottom refer to the following Flow direction of the liquid through the pack after their Proper installation in, for example, a mass transfer column.
  • upper edge region thus extends along the packing sheet edge over which the Liquid enters the flow channels formed by the sheets, and the lower Edge area accordingly along the edge of the sheet over which the liquid Leaves flow channels again.
  • the invention is particularly suitable for producing structured films of metal. For this reason, in the following the terms "foil” and “packing sheet” partly used synonymously. This formulation is not intended to limit the Invention on the structuring of metal foils represent.
  • the invention Method is also suitable to films made of other materials, for example Plastic, reshape.
  • a profiled film in particular a packing sheet for a ordered packing, provided with a corrugation, oblique to the edges of the film runs and a substantially constant angle of inclination to the edges has.
  • the corrugation continues into the edge regions of the film. It But it is also possible to provide only the main area of the film with the corrugation and not to structure the edge regions in this process step.
  • At least one edge region of the corrugated foil is by means of a formed stamp-shaped forming tool.
  • the forming tool is as a kind Executed stamp and gives the desired modification of the edge region of the film again.
  • the forming tool is pressed onto the foil, whereby the structure of the Film in the edge region is changed by the mechanical force. Subsequently, the forming tool is lifted off the film again and the Forming tool and the film are moved in the film plane relative to each other, so that another part of the film can be modified with the help of the forming tool can.
  • corrugated foils with modified edge region are arranged to produce an ordered package in parallel and usually linked together.
  • the individual foils or packing sheets then have a main area with formed by the applied corrugation Flow channels and one or two edge areas in which the structure of the Film that deviates from the main area.
  • the corrugation in the main area which is a substantially has constant angle of inclination, by means of a punch-shaped forming tool produced.
  • a stamp-shaped forming tool can do this also, analogously to the method mentioned in EP 1 044 787 B1, an or Several profiled rollers are used, over which as starting material used film are rolled while the profile located on the rollers on transfer the main area of the film.
  • the edge region is reshaped so that in the edge region of the Inclination angle of the corrugation to the edge of the edge bounding film edge greater than the constant angle of inclination of the corrugation before forming.
  • the angle of inclination of the corrugation in the edge region is more than 80 °, more preferably about 90 °.
  • the film before forming the edge region with a perforation and / or a fine profile provided to the efficiency of the film to increase the size of the pack produced.
  • the film or the packing sheet is structured in two steps. First, the entire width of the film or at least the main area the film applied a corrugation with obliquely extending to the edge of the film channels. In a second step, at least one of the two edge regions, the upper one and / or the lower edge region, by means of a stamp-shaped forming tool modified.
  • the invention uses the possibility of using a stamp-shaped Forming tool to reshape a larger portion of the film at once can.
  • Theoretically, with a single stamping process can take any length Edge areas are reshaped.
