The invention relates to a folding system for cardboard which produces a three-dimensional shape which can be rolled out from a single flat piece of cardboard. The structure of the folding system differs for each model. The object of the structure is primarily decorative. The surprise lies in opening up the structure, which unfolds into a flat sheet. When completely rolled out, the cardboard surface serves to carry messages for advertising slogans, short stories or pictures; front and rear side. The 3D form allows the structure to be used as a packaging. The models I, II, III and IV described represent variants on the principle described above. In all models, the system is cut to the size of the outer shape, i.e. 4-6-8 or 10 faces. The result is an apparent difference in structure. However, the system is the same in each case. The models are described from the rolled-out flat sheet. The cardboard structure represents an application for the graphics design industry. The design of the model may be implemented in this form by means of a punching and printing unit. The weight of the cardboard varies from 170-300 g/m2.
