<p>A method and a device for the repetitive punching from plane material of articles with a good measure precision, whereby the plane material by lateral transfer is worked in one or a number of steps in one or a number of punching stations by punching is described. The method and the device are especially characterised in that relatively narrow tabs (17-20, 33, 34) are formed, preliminarily keeping the resulting articles together.</p> |
