摘要： A compression punch for a rotary press, with a shaft, a punch head disposed at one shaft end and a compression zone disposed at the other shaft end, wherein the punch head features an upper mirror surface, an outer cylinder surface and a curved transition zone between the mirror surface and the cylinder surface, wherein the mirror surface and the transition zone form a three-dimensional surface, whose course in at least one radial direction can be described by a mathematical function whose second derivative is continuous.
