  • Patent number: 9895735
    Abstract: A method and a device are provided for joining the ends of strips with two or more surfaces arranged flat on top of each other, more particularly metal sheets that can be coiled, in order to draw these successively through a treatment or machining system. It is provided that the strip ends are joined by means of a plurality of eyelets arranged essentially transversally to the strip direction, wherein initially all holes are simultaneously punched in a first stroke and then all eyelets are pressed in a second stroke. The device has a clamping device and a machining unit, which has a working tool with a plurality of punching and pressing tools, wherein the working tool and a die are displaceable by the distance between two neighboring individual tools and wherein above the punching and pressing tools, a pressing device is provided.
