  • Patent number: 8690149
    Abstract: A receiving, holding and/or handling device for two-dimensional objects, with at least two controllable suction grippers. The suction grippers are arranged and connected to free ends of movable cantilever arms, which are elastically deformable at least in some sections. The cantilever arm are mounted and supported on a bridge. The cantilever arms each include at least one lower pull and one upper pull which meet at the free end of the cantilever arm and are connected there. An actuating device is assigned to the upper pull. The actuating device generates a pulling force with at least one horizontal direction component which is approximately parallel to the longitudinal extension direction of the cantilever arm. A method is also disclosed.
