Definitions

  • the new folding honeycomb differs from the folded honeycomb cut from the block in that it is transverse to there are bridging sections running along the honeycomb walls, form the connection surfaces for cover layers. If the Folded honeycomb is therefore used as a sandwich core layer, can be a high drum peel strength of the top layer against the sandwich core layer.
  • FIG. 1 shows a flat sheet of thin sheet metal, Plastic, fabric, fiber composite material (with carbon, Aramid or glass fibers) or fiber-reinforced paper (Nomex® paper), which after folding a sandwich core layer forms according to the invention.
  • the Folded lines drawn in dashed lines in the web which in the Folded during processing. are in detail continuous, horizontal fold lines 1, 2, 3, 4 and broken, vertical fold lines 5 and others Fold lines 7, 8 indicated.
  • To prepare the Processing can still strips of adhesive or solder 19 aligned to fold lines 5 on both sides of the web be attached. You can also go through the folds Prepare embossing lines.
  • the web walls 22 can also be used Dislocations 25, 26 are folded. This hugs you Areas of the web walls 22 to the edge areas of the web walls 14, 17 so that there is a flat connection between them vertical wall walls.
  • the hexagonal folded honeycombs described below become flat or flat bodies as before manufactured, for example thin sheet metal, Plastic film, fabric, sheet-like bevel composite (with carbon, aramid or glass fibers) or fiber-reinforced Paper (Nomex® paper), but it also becomes normal paper or cardboard considered.
  • the flat material is with incisions and then serves as Starting material for folding.
  • the strip-shaped areas 20 can be divided into two directions perpendicular to each other are folded, namely square waves can be generated, the strip-shaped areas 20 the wave crests that strip-shaped areas 21 the troughs and the strip-shaped areas 22 which form wave flanks.
  • the Curl in the direction perpendicular to it is by bending or partially folded around fold lines 5 through 8, what is called “wrinkling” here. It will Trapezoidal waves are generated which are called “half honeycomb waves Wave crests and wave sinks "are referred to.
  • FIG 23 shows an embodiment of a Cut with U-shaped cuts 9. This will flap formed by the fold line 7 and 5 in two Tab portions 14, 15 and 17, 18 are divided.
  • the other features correspond to the embodiment according to FIG 20.
  • the tab portion 14 is bent down and the Flap section 15 placed horizontally during the Tab portion 17 is bent upwards and the Tab portion 18 is also placed horizontally.
  • the Tab sections 14 and 17 After folding in two different directions, like with 21 and 22, the Tab sections 14 and 17 to respective crossbars, which enforce the respective cells 23 and 24, and Tab portions 15 and 18 become pads, which span the respective cells 23, 24, as shown in Fig. 24 is given.
  • the flap sections 15 and 18 offer additional pads for a possible Sandwich top layer.
  • the next step is the folding along the continuous fold lines 1, 2, 3 and 4, where Square waves arise in their wave crests or Wave valleys to lie the pads 13 and 16 respectively come.
  • the material is shortened again.
  • Fig. 31 shows a blank of material that is can be deep drawn or deformed in a similar way. This happens all light metal into consideration, but can also Fabric and fiber structures from a layer plane permanently deform, possibly also with the participation of Warmth and moisture (paper, cardboard).
  • the intended Deformation is caused by fold lines 1, 2, 3, 4 and 5, 6, 7, 8 indicated.
  • fold lines 1, 2, 3, 4 run slit-like cuts 9, between which there are stripe-shaped regions 20, 21, 22 extend.
  • the slots 9 face each other opposite, and this also applies to the strip-shaped Areas 21 too, but the slit-like incisions 9 of the area 20 with respect to the slot-like incisions 9 of area 21 offset from one another.
  • Between slot-like incisions 9 are bridging sections 13 and 16 provided so that the web shown one forms a coherent, flat body.
