| 摘要 | A method for the three-dimensional shaping of flat material made from in particular, natural fibers, such as for example, paper or cardboard, using a deep-drawing piston and a die, through which or into which the material is drawn. The diameter of the deep-drawing piston plus the material thickness of the deep-drawn material corresponds at least approximately to the diameter of the die. | ||||||
