<p>In a device (10) for producing a hole (62) in a sheet-shaped material (60) with a hole tool (20) and a die plate (30), the hole tool (20) is arranged at a first element (40) rotating about a first axis (A1) and the die plate (30) is arranged at a second element (50) rotating about a second axis (A2). The die plate (30) is manufactured of a hard, wear resistant, reversibly deformable material. Arranged between the second element (50) and the die plate (30) is an elastic layer (32) which has a lesser hardness than the die plate (30).</p> |
