The invention relates to a device for punching flat packaging elements or the like such as sheets (30) of paper, cardboard or corrugated board, comprising punching blades (14), which project from a punching die (10) while serving as a shaping or cutting element. According to the invention, the sheet (30) placed on a supporting punching plate (20) is assigned to the blade tips or cutting edges (16) of the punching blades (14), and a layer (26) made of a magnetic material is placed between the surface (22) of the supporting punching plate (20) and the sheet (30) to be punched. The layer (26) is made of an elastic magnetic material, optionally from a magnetized plastic. It can be provided in the form of a thin mat (26), which is made of magnetic material and which spans the contact surface (22) for the sheets (30) to be punched. |
