Definitions

  • the invention relates to a device according to the preamble of claim 1 and claim 8.
  • honeycomb panels with polygonal or round honeycomb cells have hitherto been produced in a relatively complicated manner by making the honeycomb cells from polygonal, e.g. cut hexagonal or round tubes, join them together, glue them together and then glue them to an upper and a lower cover plate. Such a process requires a relatively large amount of work and leads to expensive products.
  • the object of the invention is to manufacture honeycomb panels made of paper, plastic film, metal foil or the like. Light and thin material in a continuous operation from material rolls to the finished product in a simple and cost-effective manner and to achieve a uniform, honeycomb-like structure with the same weight results in a higher stability.
  • a smooth web of material that is unwound from a roll of material is first folded symmetrically in the transverse direction in a folding device, so that the fold lines are equidistant from one another. Subsequently, adhesive in strip form is applied continuously, interrupted or punctually on the top and bottom of the folded material web.
  • the strip-shaped adhesive application is applied in parallel lines in the longitudinal direction of the web and preferably on the top and the bottom at a distance which corresponds approximately to twice the cell diameter.
  • the web of material is then folded and pressed together so that the mutually facing sides of the folds are pressed together and over the glue points be glued together.
  • the material web in the pressed state is ground, milled or cut off on the top and bottom so that the top and lower edges of the folding surfaces are removed, so that the surfaces forming the folds are only connected to one another via the adhesive points, ie the connections of the fold lines are separated from one another.
  • the adhesive connections of three corners of the cells represent the connection points, which are each offset by a corner connection after gluing, so that approximately hexagonal cells are formed during stretching.
  • the material web can also be rolled up on rolls without stretching.
  • an upper and a lower cover sheet are applied to the honeycomb material web. Both cover sheets are each pulled off a roll and the underside of the upper and the upper side of the lower cover sheet is glued to the bottom and the top of the honeycomb material sheet by means of adhesive. The two cover sheets and the honeycomb material sheet are then pressed against one another and dried so that the adhesive is effective. Alternatively, the adhesive can also be applied to the two opposite end faces of the honeycomb material web, and the cover webs are then pressed on. After drying, the finished honeycomb sheet with top and bottom layers is cut into sheets of the desired length and stored. Alternatively, only an upper or a lower cover sheet can be applied for certain applications.
  • honeycomb panel according to the invention compared to conventional comparable honeycomb panels achieved that the total weight of the finished panel can be kept lower with the same strength, the production of such honeycomb panels is extremely simple compared to conventional panels, sheet material in the form of thin layers or foils made of paper, plastic, sheet metal, fabric, wood and the like can be used for the honeycomb material, provided that this material meets the requirements for deformability, by sanding the upper and lower fold edges, a higher roughness, better planarity and thus a better bondability in the forehead bond is achieved, and the production can be achieved in one continuous operation from a roll of material.
  • the folded web of material is pressed, as indicated by 6, and the upper edge and the lower edge of the folds are ground, as shown by 7.
  • the material web treated in this way is stretched, and the result is the honeycomb-shaped material web 8, which is connected to an upper cover sheet 9 and a lower cover sheet 10 on the top and the bottom.
  • the finished honeycomb panel 8, 9, 10, which is in the form of a web, is cut to the desired panel lengths.
  • the device for producing such a honeycomb panel is shown in FIG. 2.
  • the web 1 is guided from a roll of material 11 through a folding device 14 consisting of two folding tools 12, 13.
  • the folded material web 14 then passes through an upper glue application device 15 and a lower glue application device 16, which apply the strip-shaped glue application 3, 4 to the top and the bottom of the material web 14.
  • the glue application devices 15, 16 are glue application rollers which take glue from glue containers and apply it to the folded material web at the predetermined locations, which appear as the connection points between two abutting sides of two adjacent cells in the honeycomb pattern.
  • the material web glued at the strip locations 3, 4 passes through a folding mechanism 17 which folds the material web at the fold lines.
  • a pressing and drying section 18 at the entrance of which feed rollers 19, 20 are arranged on both sides of the material web, and at the end of which pressure rollers 21, 22 are provided.
  • the folded web of material is pressed together so that the individual folds come into contact with one another and are glued to one another at the locations provided for this purpose.
  • the counter pressure rollers 21, 22 effect the pressing process.
  • 23, 24 a grinding device is shown schematically, which grinds or removes the upper edge and the lower edge of the folds 5 of the material web 14 and to remove the connection of two adjacent surfaces of the fold for the honeycomb formation.
  • feed rollers 25, 26, fix the material web at the beginning of the stretching section 27.
  • glue applicators 30, 31 which apply glue to the top and bottom of the stretched web of material to secure the top and bottom cover webs.
  • 32 denotes a pressing and drying section, with 33, 34 a cross-cutting device is indicated, and with 35 the cut honeycomb panels are shown as a finished product.
  • the upper cover sheet 37 is drawn off from a cover sheet roll 36, the lower cover sheet 39 from a material roll 38.
