1. Folded honeycomb, formed from a plurality of cells arranged in rows, with the following features: the cells have lateral cell walls which adjoin one another in the form of a ring and are bounded toward two opening sides of the cell by covering-layer planes;a cell wall of one cell adjoining the cell wall of another cell in a honeycomb structure;the folded honeycomb has a plurality of polygonally, sinusoidally or arcuately shaped regions and strip-shaped regions;the polygonally, sinusoidally or arcuately shaped regions are folded through about 90° with respect to the strip-shaped regions;in whichthe cells are each bridged completely in the two covering-layer planes;the folded honeycomb is formed from a substantially uncut flat body;the plurality of polygonally, sinusoidally or arcuately shaped regions are formed by plastic deformation of the substantially uncut body; andsub-areas produced by the plastic deformation lie on the strip-shaped regions in the covering-layer planes.2. Folded honeycomb according to claim 1, in which at least a part of the cell walls are wholly or partly permanently connected to one another.3. Folded honeycomb according to claim 1, in which the sub-areas produced by the plastic deformation are wholly or partly permanently connected to surface areas lying on them and belonging to the strip-shaped regions.4. Folded honeycomb according to claim 2, in which that the sub-areas produced by the plastic deformation are wholly or partly permanently connected to the surface areas lying on them and belonging to the strip-shaped regions.5. Folded honeycomb according to claim 1, in which the body is a thermoplastic polymer, a fiber composite material or a plastically deformable paper or metal sheet.6. Folded honeycomb according to claim 1, in which the cells are all the same.7. Process for producing a folded honeycomb as defined in claim 1, with the following steps:a) a flat body composed of a plastically deformable material is provided;b) the flat body is polygonally, sinusoidally or arcuately plastically deformed in first strip-shaped regions, second strip-shaped regions located between the first strip-shaped regions being alternately formed wholly in the plane of the flat initial body or out of this plane; andc) the polygonally, sinusoidally or arcuately plastically formed regions are folded through about 90° with respect to the second strip-shaped regions to form cells having cell walls which adjoin one another in the form of a ring so that a cell wall of one cell adjoins the cell wall of another cell in a honeycomb structure.8. Process according to claim 7, in which at least a part of mutually contacting surface areas and/or edges are firmly connected to one another.9. Process according to claim 7, in which the deformable material is a thermoplastic polymer, a fiber composite material or a plastically deformable paper or metal sheet.10. Process according to claim 7, in which the polygonal, sinusoidal or arcuate plastic deformation is carried out by means of a non-cutting rotation process.11. Process according to claim 7, which the deformation is carried out by means of a rotation-thermoforming process.
